Dear Mark, Jim Garrison, Don Williams (Tukwila Parks and Recreation), and I met at the Rabanco site to resolve the SEPA mitigation condition regarding screening of the project from Foster Golf Course. The following replacement of screening trees was agreed to by Rabanco and the City of Tukwila: 1. The earthen bench on the north of the building, between the two retaining walls, will be landscaped with 8 evergreen trees in three clusters. Four trees will be a minimum 6 ft. high and four will have a minimum 8 ft. height. All trees will be balled and burlapped and well branched. Trees similar to Douglas Firs are favored. 2. The earthen slope on the south of the building will be landscaped with evergreen trees approximately 15 feet on center, planted in a triangular pattern. Tree spacing will be revised based on species and size at planting. Tree characteristics will be as described in 1; except that a highly sun tolerant species will be used. 3. An automatic irrigation system will be installed to serve all planted areas. 4. The bottom base of the westerly building elevation will be planted a dark earthen color (e.g., chocolate brown) to visually break up the wall. This color band will extend from the metal siding "cut -out" on the north, to the mirror cut out on the south. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • (206) 431 -3670 • Fax (206) 431-3665 s..• ECF;RVMP- 082 -90 tanco Mitigation) June 9, 1994 1 Page 2 Based on the above provisions, the City of Tukwila waives the need to satisfy Mitigation Document condition 25(b) (landscape planting along the westerly project site and adjacent to the south, west and north building faces).

Both Chuck and Marty were concerned that there was no space for the trees and that addition of trees would block sunlight from the green. They also felt that unless the trees were very tall, that as a screen they would not be effective. It was suggested that some trees maybe placed between the railroad tracks as a possible alternative. Please contact Marty or Chuck for any additional comments. It was generally agreed that no trees were needed. They did, however, suggest that trees be planted to shield the rendering works. RECE VE JUN 1 01994 COMMUNiry DEVELOPMENT MEMORANDUM TO: Vernon Umetsu, Associate Planner Jack Pace, Senior Planner FROM: Gary Schulz, Urban Environmentalist DATE: June 2, 1994 RE: Rabanco - Black River Waste Reduction Center In reply to your 5/23/94 memo, I have reviewed Watershed Dynamic's water quality baseline report. The . report appears to be adequate but I asked them to review their scope of work and monitoring schedule. Based on a site visit yesterday, the stormwater facility has erosion problems that may become serious and affect the water quality that discharges into the Tukwila wetland and Duwamish River. As we discussed, the', "wetlands buffer planting plan" submitted to us is not a detailed or complete plan. The "plan" does not appear to have been prepared by a professional biologist or landscape architect. Watershed Dynamics did create a conceptual enhancement plan; however., because the site plan has changed their original plan should be revised. Coordination with Rabanco is needed to prepare an appropriate wetland enhancement plan, and to monitor the post- construction stormwater discharge. Let me know if you have questions or need help communicating with Rabanco. cc: Rick Beeler, DCD Director MEMORANDUM To: Gary Schulz From: Vernon Umetsu Date: 5/23/94 RE: Rabanco Water Quality Monitoring and Wetland Buffer Planting. Rabanco has submitted the results of the first water quality monitoring and a proposed wetland buffer area planting for our review and comment. This was required as part of the joint mitigation agreement. Please note that the construction was revised after the EIS, to avoid any work in the buffer area which lies in Tukwila city limits. Never - the -less, enhancement is required. Please get back to me by Wednesday with your comments.

The.acquaint.you with the'issue, the City of Renton has • requested that I re -visit the screening tree proposal made under the DEIS with the City of Tukwila. As you may recall, the DEIS suggested a potential visual screen'planting area near the Foster Golf Course. The City of Tukwila rejected that proposal in a commentietter to the City of Renton: dated June 17, 1991. It was again rejected by 4- Tukwila in oral testimony during the 'public hearing process. In response to that comment as included in the FEIS, the City of Renton clarified the planting proposal at the golf course and concluded:: if the -City of Tukwila will not consider allowing vegetative screening on•the east side of the•golf course, then other effective mitigation suggested in the DEIS, such as planting on thewest side -of the site, could be- required instead: This screening will'be subject to the final mitigation document. (Emphasis added), Language within the Mitigation.Document clearly,anticipated that the. safe. loading and Movement of rail cars and' equipment; would 'be the primary determining factor,in • plantings'on.the west side of the building and /or:rail lines.

(Emphasis added). In that,the mitigation document is the,applicable document onn this point, and:that the plantings would be subject to railroad approval, the Mitigation Document anticipated that the railroad might reject the plantings.

As you know, I am limited on the amount of wetland consulting I can provide to a non -City private project. My role is more technical and review oriented. I have reservations about spending time on a project that was permitted in the City of Renton. As I reviewed both mitigation documents it is clear that the City of Renton was the responsible party for selecting a wetland consultant and reviewing all mitigation and monitoring plans. In addition, all of the mitigations were to be approved and installed prior to Renton issuing the occupancy permits. My original direction from Rick Beeler was to not get involved with the developer ( Rabanco) unless City of Renton staff were also participating. Therefore, I have reservations about coordinating with the developer on this project. I feel I should review any related enhancement plans after their submittal to the City of Renton. Also, the only inspections I should be involved with are when the enhancement /mitigation plans are being constructed on the site. In summary, it appears the mitigation documents were not implemented as written and this puts Tukwila in an awkward position. Aside from the project already being permitted, a significant amount of area was graded and developed that may have been used for mitigation per the documents. I don't believe coordination with the project's developer, prior to submittal of a completed plan, is an appropriate role for me to assume. Let me know if we need to schedule a meeting to resolve the issues. cc: Rick Beeler, DCD Director MEMORANDUM To: Rick Beeler and Gary Schulz From: Vernon Umetsu Date: 2/10/94 RE: Coordination of Rabanco Wetland Enhancement and Water Quality Monitoring I'm drafting this memo to be sure that we're all starting out with the same understanding.

Three of these were sedimentation ponds. Through examination of air photos these were determined to be man-made conditions and not regulated under the U.S. Army Corps of Engineers Nationwide permit, the King County Sensitive Areas Ordinance, City of Renton ordinances, or the DOE Model Ordinance. Two other wetlands, a natural hillside /roadway drainage swale (less than 1000 sq. ft.) and a small depressional area (1500 sq. ft.) are located on a bench adjacent to Beacon -Coal Mine Road. These two areas were exempt from wetland regulations due to their small size. As these two wetlands were thought to be located outside of the construction zone, they were not included in the report. The remaining wetland occurs at the north end of the site in a natural drainage swale. This wetland was thought to be in King County and, therefore, regulated under the King County Sensitive Areas Ordinance. Because this wetland covers less than one acre in size, is not forested, and has no threatened or endangered plants or animals, it was classified by the County as a Class 3 wetland. This wetland was the subject of a wetland report prepared by Parametrix in December, 1990. Following completion of this report, more definitive maps of City of Tukwila boundaries indicated this wetland to be in their jurisdiction. Based on our understanding of the project at the time the wetlands report and EIS were prepared, no activity was to occur in any regulated wetland and we continue to support this conclucion.

Regulations and ouidelines implementing our permit program under Seotion 404 of the clean Water Act renuired thet, effective July 25, 1975, you must obtain a Section 404 permit prior to the discherTe of any dredged or fill material into these waters of the United States including wetlands. The term "wetlands" means those areas that are inundated or saturated by surface or ground water et a frecuency and duration sufficient to support, and that under normal circumstances Ho support a prevalence of vegetation typically adapted for life in saturated soil conditions. The Corps of Enoineers has the respon- sibility for determining whether e specific wetland area is within Section 404 jurisdiction. As indicated on the enclosed sketch, the area north of the berm is wetlands. The term "adjacent" means borderinn, contiguous, or neighbor- ing. Wetlands separated from other waters of the United States by manmade dikes or harriers, natural river berms, beach dunes, and the Like are "adjacent wetlands."

The suggested modified mitigating measures would allow a more realistic comparison of impacts and mitigating actions, and make any final conclusions much more valid. DEIS COMMENT: The additional view analyses requested have been provided. DEIS COMMENT: (Page 3-44). It is not explained why plantings at Foster Golf Course would result in a more effective vegetative screen for the project in a much shorter time than on site plantings as is normally required. A review of the site plan shows many opportunities for not only on site plantings, but plantings of large stature evergreen trees adjacent to the structures where they would be most effective in breaking up the large wall masses. SEPA guidelines usually require mitigation to be done on the project site, as should be the case here. Tukwila's Parks and Recreation Director is, at this time, not amenable to plantings on the Golf Course property. As you might imagine, sunlight is essential for grass growth especially on tee and greens areas, and any additional plantings on the course would provide more shaded areas and unacceptably inhibit Section 3.8 of the DEIS addresses transportation issues. Although the project's peak hour traffic volumes generated will not make a measurable difference in the service level at Interurban/Grady Way �r at West Valley Highway /S. 156th Street, they will further degrade traffic flow. The existing level of service is F, and the improvements will cost over 511,000,000. A Black River proportionate share of those costs based on traffic volume increase, as we use with other developments, would be unfair due to the high cost of this improvement. The trip fee approach has been used with other developments generating traffic in the interchange, and we feel that the Black River development should be treated similarly. That is, a mitigation fee of 51,000 per peak hour trip would be assessed for use in funding the planned capacity improvements. The Black River development $1,000 /trip would be for: Interurban/Grady southbound lefts increase 5 eastbound throughs increase 29 westbound lefts increase 8 Total 42 W. Valley Hwy /South 156th. St. eastbound lefts southbound rights Total 34 7 41 ro 4- T(.IPS © &I,0007T2( P #83,000 1ltti ? /ON This is computed based on the DEIS a.m. peak hour data, which provides volume projection but proposes . no mitigation for its affect on the Interurban/I -405 interchange. A final concern of mine is wetlands. A wetland is shown in Figure 1 -3, but it does not seem to correspond to what I found on a visit to the site. It is also evident that some wetland filling has taken place over a period of some years. I would like to know how the filling was done, who performed the filling, was the City of Renton aware of this filling, and were proper permits obtained? Earl Clymer, Mayor AITYA µr � RENTON Planning /Building /Public Works Department Lynn Guttmann, Administrator November 8, 1991 SUBJECT: Rabanco /Black River CDL Recycling and Transfer Station ECF;RVMP -082 -90 Dear Interested Party: This is to inform you that, under SEPA, RCW 43.21C.075 and WAC 197 -11 -660, the City of Renton has issued a mitigation document for the Rabanco /Black River CDL Recycling and Transfer Station Environmental Impact Statement. Copies of the document are available at the public information counter (SEPA Information Center) in the Development Services Division, Third Floor, Renton Municipal Building located at 200 Mill Avenue South, Renton, Washington 98055. Reading copies are available in the Renton Municipal Library at the above address. DESCRIPTION OF PROPOSAL: The applicant seeks environmental review and a routine vegetation management permit for a recycling and transfer operation employing manual and mechanical processes to remove recyclable material from construction, demolition, and landclearing debris. Any interested party may appeal these conditions in writing by 5:00 p.m., December 2, 1991. See City • Code Section 4 -8 -11, WAC 197 - 11-680 for further details and RCW 43.21C.075. Any appeal as to the adequacy of the EIS must be filed with the Hearing Examiner within twenty (20) days of the date the decision was made to issue the mitigation document. All appeals must be received by December 2, 1991, 5:00 p.m. You should be prepared to make specific factual objections to either the mitigation document and /or the EIS. If you have any questions about the procedures for either appeal, please contact Mark Pywell at 235 -2550. er Donald K Erickson, AICP Zoning Administrator mildc@r 200 Mill Avenue South - Renton, Washington 98055 RECOMMENDATIONS: 32) The applicant shall, in order to ensure that the routes used by the trucks . accessing the project site are not adversely impacted, provide a proposed truck routes map to the satisfaction of the Development Services Division and the Transportation Systems Division prior to the issuance of building permits. This map shall indicate the routes trucks will use from the roads included in the proposed Truck Routes Ordinance to the project site. The . applicant shall encourage all truck drivers to adhere to the prescribed routes which have been designed and constructed to handle trucks. Copies of this map shall be mailed, on a semi - annual schedule, to the hauling firms and handed to the truck drivers to reinforce the use of designated truck routes. 33) The applicant shall, in order to mitigate potential adverse impacts to the road surface and bridges, sign an agreement with the City of Renton, prior to the issuance of building permits, which allows the City to recover costs associated with unusual wear and tear to road surfaces including bridge deck surfaces. The methodology of the agreement shall be as follows: S = (A) X (0.2) [(C' - C) / D] X (Truck Ratio) Where: S = The proportion of the total cost attributable to a given project or development (i.e. The Black River Recycle and Transfer Center). A = Cost of the overlay (One inch of overlay plus prelevel and preparation work).. C' = Measured change in pavement condition rating (PCR) during the survey period. PCR at beginning of monitoring period - PCR at the end of the monitoring period. = Normal change in PCR for the same time period. Determined by monitoring PCR conditions one year prior to opening (Would likely range between 5 and 15 points per year). D = Typical overlay life in years. Truck Ratio = Projected Generated Traffic (PGT) divided by Average Daily Truck Traffic (ADT) times the number of days the project is operational, plus Project Generated Traffic. The cost of the analysis described above shall be borne by the applicant. 34) The applicant shall, in order to mitigate impacts to the streets within the City of Tukwila, sign an agreement with the City of Tukwila, prior to the issuance of occupancy permits by the City of Renton, to provide a one -time fee of $1,000.00 per peak -hour trip expected to be generated by the project through the intersection of Interurban Avenue /Grady Way and West Valley Highway /South 156th Street provided that the applicant has reviewed and verified the basis for the fair share calculations. 35) The applicant shall, in order to reduce the potential for accidents occurring at the entrance to the project site, install a signal device or other traffic control devices deemed appropriate by the Transportation Systems Division. Any required traffic safety device or signal shall be installed prior to the issuance of occupancy permits unless a deferral is obtained from the City of Renton Board of Public Works. A & &.

WHEREAS the subject property is designated for Light Industrial (L -1) land uses on the City of Renton Zoning Map and the City of Renton has determined that the proposed land use is a permitted land use within this zone; and 5. WHEREAS the proposed CDL Station with associated facilities and site preparation formed the basis for the City's final environmental review, and the preliminary site plan and elevations are attached hereto as Exhibits A and B and by this reference incorporated herein (these site plans and the proposed development depicted therein referred to together hereinafter as "the Project"); the preliminary site plan and elevations may be amended in the future with the approval of Renton in order to reduce or mitigate the impacts of the proposed development; and • 1 6. WHEREAS the City of Renton, in a close working relationship with the City of Tukwila, has prepared a Final Environmental Impact Statement ( "FEIS ") which was issued in August 1991 and an Environmental Mitigation Document which was issued by the City's Environmental Review Committee ( "the ERC ") in November 1991 (together, "ERC Document "), which ERC Document included the comments received from the City of Tukwila as well as comments received from the public and also contained mitigation conditions applicable to the Project; and 7. WHEREAS the City of Tukwila appealed the ERC Document, on December 2, 1991 to the City of Renton Hearing Examiner ("Hearing Examiner"); and 8. WHEREAS Renton has consulted with the representatives of the Parties involved in the appeals noted above regarding how best to clarify the mitigation measures identified within the ERC documents; and 9. WHEREAS the City of Renton, City of Tukwila, and Rabanco have agreed: 1) to review noise complaints and to determine the parameters of the noise analysis required by the City of Renton; 2) work with the U.S. Army Corps of Engineers to identify additional potential wetland areas; 3) clarify and refine the wetland monitoring program; 4) review the hours of operation; and monitor the noise mitigation program; and . 10. WHEREAS the Parties involved each believes that it would prevail in its position and assertions regarding the above - described appeals and the City of Renton believes it would prevail in defense of the FEIS and ERC Document, and each of the Parties believes it would prevail in any subsequent litigation regarding this matter, but at the same time has given due consideration to the clarification of the issues and the new information outlined above, the unavoidable delays and hazards of these appeals and the expenses connected thereto, and has recognized desirability of terminating this appeal on the subject property without further expense and litigation; and 11. WHEREAS the Parties wish to ensure that the proposed project complies with the Code - requirements and standards established at the time that the Project was approved by the City of Renton; and • • 12. WHEREAS Tukwila is extremely concerned that the noise generated from the proposed Project could exceed the limits established by ordinance but, nevertheless, in order to settle these disputes, Tukwila has agreed to drop their appeal of the ERC Document and the FEIS based on the terms and conditions hereof, and Tukwila agrees not to oppose other governmental approvals, that are consistent with this agreement and the ERC Document, required for the construction of the Project such as the shoreline permits, special fill and grade permits and building permits for the Project, as further set forth in this Agreement. NOW THEREFORE, IN CONSIDERATION of mutual promises and agreements contained herein the legal sufficiency of which is hereby acknowledge by the Parties on behalf of themselves, their officers, directors , and Tukwila and Renton hereby agree as follows with the intent that each is legally bound: II. ENVIRONMENTAL MITIGATION CONDITIONS A. Mitigation Conditions Controlling. 1. The Mitigation Conditions contained herein are for the purpose of clarifying and adding to the conditions in the Mitigation Document and are considered Final. In the case of a conflict between the Mitigation Measures contained within the Mitigation Document and the Mitigation Conditions contained herein, such as the hours of operation, the Mitigation Conditions shall prevail. Renton agrees that the environmental mitigation conditions listed in Section II of this Agreement will clarify and in the case of conflicts will supersede the ERC Document and taken together the documents will constitute the environmental mitigation measures for the Project. Renton and Tukwila agree that the these mitigation measures will fully mitigate all environmental impacts from the Project as it is currently proposed, and that no further mitigation is necessary or appropriate with regard to the subject matter of this Agreement notwithstanding future mitigation as set forth in Section II.A.2.a below. The City Departments agree to recommend imposition of these Mitigation Measures and Conditions or to impose them. Renton also agrees to impose no further mitigation conditions with respect to the subject matters addressed in the Mitigation Measures and Mitigation Conditions, on all approvals required for the construction and operation of the Project, except as provided in Section II.A.2 below. 2. Relationship of Mitigation Conditions to Required Permits and Approvals. a. Other Permits and Approvals Required. The Parties recognize that in addition to the environmental approval embodied by the ERC Document and the Mitigation Conditions, Rabanco is required to obtain other permits and approvals, such as a shoreline permit and construction permits. In that regard, this Agreement acknowledges that more specific mitigation may be required by these permits in that they may cause a modification to the site plan as described in the ERC Documents. The Parties agree that Tukwila shall be informed by Renton and have a fifteen days to review and comment on these applications prior to the issuance of the permits by the City of Renton. b. Additional Conditions to Be Consistent With Mitigation Conditions. The Parties desire to have as much certainty as possible regarding the conditions for the Project and hereby state their intent that the conditions of the permits and approvals for the Project will not conflict with, materially enlarge or modify the Mitigation Conditions herein. To that end, Renton agrees that it will only impose additional conditions to the Mitigation Conditions on the Project which do not conflict with, enlarge or modify the Mitigation Conditions unless such conflict, enlargement or modification is explicitly mandated by a Renton ordinance in existence on the date of this Agreement other than the Environmental Review Ordinance, or as otherwise provided for in this Agreement. The Parties also recognize that while they wish to bind themselves as much as possible, this Agreement cannot legally bind a future Renton City Council and that it cannot bind quasi - judicial decisionmakers regarding permits and approvals for the Revised Project. 3. Project to Substantially Comply with Mitigation Conditions and the ERC Documents. Rabanco agrees that its application for shoreline permit and other approvals required for development pursuant to this Agreement will be for a project that is revised to substantially conform to all of the Mitigation Conditions of this Agreement and the ERC Document; provided that substantially conform means that Rabanco may make "minor adjustments" to the Project, "minor adjustment" defined herein as any change that is less than a "major adjustment" as defined below ( "Minor Adjustment "), which Minor Adjustment shall also be within the terms and spirit and intent of this Agreement, without written consent of the parties. 4. Modification to Project Require Agreement. If Rabanco desires to make a major adjustment to. the Project, which "major adjustment" is defined herein to be a substantial change in the Project, or an increase in the total square footage of the building or site area as described in the ERC Document, Rabanco must first obtain written permission from Renton Planning staff. Such "major adjustment" to the Project may require additional environmental review which Renton agrees to perform in accordance with the SEPA guidelines and the Renton Environmental Review Ordinance. Prior to the issuance of permits for any amendment to the Project which Renton considers to be a "major adjustment ", Tukwila shall be informed by Renton and have a fifteen day review and comment period. Any comments received from Tukwila within this period shall be considered by the City of Renton in any conditions attached to the permits. B. Conditions Regarding Tukwila Permits, Potential Wetland Area, Wetlands Monitoring, Hours of Operation, and Noise Monitoring. 1. Tukwila Permits. The proposed development does not require any development or other permits from the City of Tukwila. In the event that any modifications to the proposed development make a change that would require any permits from Tukwila, Rabanco agrees to submit the necessary documents and make the necessary applications. Tukwila agrees to process that application in an expeditious manner in order to not unduly delay the proposed development. As a courtesy to Tukwila, Rabanco shall submit, concurrent with the s,bmittal to Renton, copies of the same fill /grade and drainage plans to Tukwila with an opportunity for a courtesy review of the same plans. Renton agrees to take under advisement any reasonable comments provided by Tukwila regarding the quantity and quality of the storm flows into the approvals issued by Renton. 2. Identification of Potential Wetland Area. In order to provide further opportunity for analysis of the existence of wetlands, the area of the Rabanco plans which are labeled "settling pond" shall on an interim basis be considered a study area. This area is reflected as "Study Area on the map attached as Exhibit . The study area shall include, on an interim basis, a one hundred foot (100') wide setback area. The Parties hereto agree to abide by the conclusion of the U.S. Army Corps of Engineers ("Corps ") in its determination of whether the study area includes wetlands. In the event that wetland areas are found within the study area resulting in the need for a setback area, the setback area may be used to accommodate any replacement wetland area as will as all required buffers. Any replacement area required which might otherwise exceed the one hundred foot setback shall not be required and shall be substituted with enhancement of the buffer area instead at the discretion of the City of Renton. Upon the final conclusion of the Corps and the establishment of the final setback and buffer area, the development plans shall be revised and only that portion of the study area affected by the conclusion of the wetland analysis shall be restricted in any way. The final wetland and buffer area shall be established in a manner consistent with the policies and regulations of Renton. 3. Wetland Monitoring Program. In the event that wetland areas are concluded by the Corps to exist in the study area, this wetland shall be included in the wetland monitoring program as identified in the Mitigation Document to be established by the City of Renton in conjunction with the appropriate state and federal agencies. The monitoring program may include the following elements: a. Pre - development soil sampling at the biofiltration swale site, water /soil sampling and a plant /animal baseline inventory at the wetlands. • • b. Semi - annual sampling /monitoring of the biofiltration swale and wetlands areas for changes to pre - development conditions for the first five years of operations. The monitoring shall be conducted by a consultant approved by the City of Renton with all costs being born by Rabanco, as identified in the Mitigation Document. c. Any adverse impacts which are identified as a result of the monitoring shall be immediately mitigated by Rabanco once a mitigation plan is agreed upon by Renton. Additional monitoring shall also be instituted to establish the effectiveness of mitigating actions and the absence of secondary adverse impacts. 4. Noise Mitigation Program. Rabanco, Tukwila, and Renton shall establish a committee to resolve noise issues regarding the proposed project (hereafter referred to as the Committee "). The Committee shall be composed of three members, one member from Rabanco, one member from Tukwila City staff, and one member from Renton City staff, the members shall be selected by their respective City with Rabanco selecting its own member. The Committee shall meet within five months of the start of operation with the noise consultant, selected by the City of Renton. The purpose of the Committee shall be: 1) to discuss any noise complaints that have been received 2) discuss the parameters of the proposed noise study with the consultant, including frequency of the testing and location of the noise monitoring stations, * (see note below) and 3) to review the abatement measures, if any, proposed by the noise consultant. The budget for the noise study shall be the $25,000.00 established as part of Mitigation Measure #19 in the Mitigation Document. The Committee shall be reconvened within six months of the issuance of the occupancy permit for any cumulative material expansion which shall be considered, any expansion to the Project equal to twenty -five percent (25 %) or more of the gross floor area of the process building described in the EIS Document. The purpose of the Committee at this time will be to review any noise nuisance complaints received since the expansion of the Project and to advise Renton as to any future actions the Committee may feel are necessary. Funding for such improvements may be paid from any unspent funds in the surety device identified and called for in Item 19 of the Mitigation Document. In the event that there is a dispute over the recommendations which cannot be resolved by the Committee, the City of Tukwila's Community Development Director and the City of Renton's Administrator of Planning /Building /Public Works ( "the Directors ") will apply their best efforts to resolve disputes and other matters between the Committee members arising out of or related to • noise nuisance and /or the proposed noise study. Each of the Directors shall consult with their responsible staff members and officials regarding existing requirements and /or other policies and procedures before attempting to resolve the dispute. If the Directors are unable to resolve a matter within fifteen (15) days of the time such matter Is properly referred to them, the Directors shall request the Mayor of Tukwila and the Mayor of Renton to resolve the dispute, subject to applicable statutory permit requirements, policies, or procedures. The management of Rabanco may also request that one of the Directors refer an issue to the Mayors for resolution. The Mayors may call upon the Committee or the Directors for assistance. The final decision shall be established in a manner consistent with the policies and regulations of Renton. All parties (City of Tukwila, Rabanco, City of Renton) agree that these procedural steps shall be the sole mechanisms to resolve this dispute. Note: Noise measurements taken as part of this study in Tukwila will be compared to the maximum levels allowed in Tukwila as of the date the Final EIS was issued. 5. Hours of Operation. The hours of operation shall be 8:00 a.m. to 8:00 p.m. Monday through Friday and 8:00- a:rn. to 6:00 p.m. on Saturdays and the facility shall be closed on Sunday's and major National Holidays (e.g. New Years, Christmas, July 4th, Thanksgiving). Rabanco agrees to abide by the night noise level standards from 8 a.m. to 10 a.m. and from 4 p.m. to 6 p.m. on Saturdays. In the event that the maximum allowable noise levels as established by Renton or Tukwila noise regulations as applied in the respective jurisdictions, as of the date of the Final EIS, are routinely exceeded by Rabanco's operation, Renton shall have the discretion to shorten the hours of operation in the event that Rabanco is unable to mitigate the noise impacts and bring the noise levels within the standards of the Renton and Tukwila regulations, as of the date of the Final EIS, within thirty (30) days of implementing a noise mitigation program. 111.

Re: Rabanco Construction Demolition Land Clearing Debris Transfer Facility, Renton, WA Dear Vernon: I have reviewed the noise section of the Black River Waste Reduction Center draft EIS and find it deficient in the following areas: On page 3 -20, Table 3.5 -1 is misleading. Neither King County, the State of Washington or the two jurisdictions noted on this draft EIS use level equivalent (Leq) as measurement metric. The table implies a much higher sound level than is allowed. The table should be consistent with the Washington Administrative Code 173 -60 or with either the Renton or Tukwila ordinances. The table would then indicate the proper sound levels for the emitting area to the receiving areas. The equivalent sound level (Leq) is useful for planning purposes and therefore should be retained. On page 3 -22, the same concern regarding the use of Leq applies. On page 3 -24, it indicates that the facility would operate from 6:00 a.m. to 8:00 p.m., Monday through Friday, and 8:00 a.m. to 8:00 p.m. on Saturday. The 6:00 a.m. start time would violate the night time standards which are 10 decibels below the allowable day time levels. On page 3 -27;, the use of metrics (Leq, L2,5, L8.33, and L25) is unclear. L2.5, L8.33 and L25 are used for measuring the maxima in a given one hour period. Additionally, as previously noted, this is not the ordinance adopted by Renton and Tukwila. Therefore, the lower Renton and Tukwila noise criteria on the bottom of page 3 -27 are incorrect. The 3 x 4 matrix should indicate the levels noted in WAC 173 -60 or in the adopted Renton or Tukwila noise ordinances. As a final comment on page 3 -27, a draft EIS should have the measurements of the various sound levels at certain sites. If this is impossible a similar site with similar terrain should be selected and the sound level attenuation measured with distance rather than merely assuming only atmospheric and distance attenuation. This should be done at the requisite property lines and not necessarily at any residence or building as indicated on page, 3 -27.

It should be noted that there is a federal law that prohibits the use of strobe lights in place of back -up warning horns. This issue has come up at other facilities in King County and at no time has the federal government allowed the use of strobe lights as a back -up safety device in place of the back -up warning horn. King County is currently in the process of attempting to quiet the North Transfer Station by erecting concrete highway barriers in some cases as high as 15 feet to mitigate the noise in the neighborhood. Depending on terrain, this should also be considered as a mitigating measure. If you have any questions, please call me at 296 -4794.

Renton, WA 98055 RE: Appeal of Environmental Impact Statement and Mitigation Document for (Rabanco) Black River Waste Reduction Center (RVMP- 082 -90). Dear Mr. Kaufman, The City of Tukwila herewith appeals the Renton Environmental Impact Statement and Mitigation Document prepared for the Black River Waste Reduction Center (RVMP- 082 -90).. It is requested that SEPA not be completed until several violations are resolved, a project which satisfies minimum applicable State, Renton, and Tukwila development standards is proposed, and a supplemental EIS is prepared based on the modified site conditions and proposed action. This request is supported by the following findings and conclusions. FINDINGS The SEPA issues being appealed herein are: permits required, hours of operation, noise, storm water runoff, and wetlands. Each of these issues are discussed below. 1. Permits Required A. Renton Rezone Required The proposed use is not permitted in Renton's L -1 zone as discussed below. A rezone is therefore a required Renton action and should be included in the list of required permits. The project site is Zoned L -1: LIGHT INDUSTRY DISTRICT. "Purpose and Intent: The purpose of the Light Industry Zone (L -1) is to provide areas for low intensity, non - nuisance generating in terms of odor, air and water pollution, noise, vibration and glare industrial activities. RMC 4- 712(A) 1 • • The Renton Planning Division has interpreted that the proposed project is an outright permitted use in the L -1 zone based on its similarity to activities involving the: "Manufacturing, processing, assembling and packaging of articles, products or merchandise from previously prepared natural or synthetic materials." (RMC 4- 712(B)(1)(a)(4)) This is erroneous since the use is significantly more disruptive due in part to projected high volumes of heavy truck traffic, noise and vibration than the activities normally associated with this category. This is demonstrated by the environmental impact statement which is being herewith appealed. The projected bulk construction debris handling and storage, and high levels of heavy truck traffic, is clearly associated with those uses envisioned to be located in the H -1: HEAVY INDUSTRIAL DISTRICT. Heavy industrial uses envisioned for this zone are generally described in the Purpose and Intent of the zone: "Purpose and Intent: The purpose of the Heavy Industrial Zone (H -1) is to provide areas for industrial activities involving fabrication, processing, bulk handling and storage, construction and heavy transportation. In addition, other compatible uses which directly serve the needs of such industrial uses may be allowed." (Emphasis added) - RMC 4- 713(A) The Boeing Plant and old Paccar plant are examples of the activities exhibited by the overwhelming acreage of uses located in the H -1 zone. They clearly have very similar heavy truck traffic, noise and bulk handling characteristics to the proposed construction debris handling center, than uses located in Renton's L -1 zoned lands. At the very least, the proposed construction debris handling center's high volumes of heavy truck traffic would make it an L -1 conditional use as a truck terminal and associated warehouse facility (RMC 4- 712(B)(3)(d). The proposed use in fact meets the definition of Permitted Service use No. 19: "Recycling collection stations or centers, provided that they are located outside any required landscaping area." (RMC 4- 713(B)(1)(b)(19)). The mitigation document entitles the proposal as a "Recycling and transfer station ". On that basis and the above, the proposal can only be sited in the M -1 zone, not the subject L -1 zone. 2 • • B. City of Tukwila Development Permits Required. The northern most portion of the site (see Fig. 1) is in the City of Tukwila based on Tukwila's legal description (Attachment A) and as confirmed by the King County Assessor's Office. The project site plan (DEIS Fig. 1 -3) and zoning map (DEIS Fig. 3.6- 3) should be revised to reflect this Tukwila boundary and that site's M -2 (Heavy Industrial) zoning. Any improvements in this area will require Tukwila review. Potential review would include, but not be limited to a land altering (grading) permit and consistency with the City's grading and storm water standards, sensitive areas ordinance, and zoning (see Violations). C. Violations to be Corrected Prior to Completing Environmental Review. Substantial filling has occurred on the site from an unknown earlier date to very recently. This activity has occurred on the northern third of the site where unconsolidated soil, flat topography replacing the surveyed topographic depressions of 7/16/90, and a smaller than documented wetland (DEIS Fig. 1 -3) was noted on November 14th (Umetsu, 11/22/91). Renton, Tukwila, and King County have jurisdiction over this portion of the site. No fill permit has been issued by Tukwila, King County has no record of any active fill permit since 1989 (Tiffany, 11/22/91), and Renton is only now reviewing a fill permit which is not to be issued until completion of this environmental review. Filling in Tukwila's portion of this site, including possible wetland filling, is a violation of several Tukwila regulations including, but not limited to the Land Alteration and Sensitive Areas ordinances. Of particular note is the required replacement of filled wetland with new wetland area at a rate of 1:1.5, additional buffers, no increase of storm flow above predevelopment rates per King County storm water standards as adopted by Tukwila, and biofiltration prior to inflow to the wetland. The proposed action is not consistent with these regulations. Tukwila is in the process of preparing a citation for violating various development regulations. The wetland filling may also violate U.S. Army Corps of Engineers (Corps) regulations which require a nation -wide permit. Tukwila will be contacting the Corps for enforcement assistance once the scope of violation is established, and a determination of adjacency with the Duwamish River. Tukwila's wetland replacement requirements may significantly alter the site's initial characteristics and significant changes 3 • • to the site plan are needed to satisfy minimum development standards. Therefore, it is premature to complete the SEPA process prior to a resolution of all violations. Only then will an environmental baseline for impact analysis be established and a revised proposal which satisfies the immediate minimum development standards may then be submitted and evaluated. D. Amend the King County Comprehensive Solid Waste Plan and implementing ordinance No. 10111 (9/23/91) relating to disposal of construction demolition and land clearing debris. Both the plan and ordinance envision transfer stations for collecting and transporting clean construction demolition debris. The DEIS acknowledges the likelihood of "incidental" hazardous substances being mixed in with clean debris (DEIS Pg. 1 -10). The proposal to monitor and control with staff who would be trained to note and turn away discrete loads of hazardous waste does not address the mixed load impacts on surface water runoff quality and airborne particulate as discussed in Tukwila DEIS comments. Controlling hazardous mixed loads with applicant staff does not provide the appropriate level of trained, independent public enforcement or fiscal sanctions needed to adequately control such dumping. A hazardous waste management plan should at the very least be approved by the King County Public Health Department, which has extensive experience in this area; reflect input from Seattle inspectors who monitor Rabanco's south Seattle waste collection center; and be subject to SEPA review. Lack of the needed controls to minimize mixed hazardous wastes or data justifying the proposed level of control, requires amending the policy decisions reflected in plan and ordinance. 2. Hours of Operation The proposed hours of operation are 7 a.m. to 8 p.m. seven days a week. These hours will generate significant, cumulative nuisance impacts due to the unmitigated noise, dust, and vibration of this industrial activity in the early morning and evening. Cumulative nuisance impacts will be accentuated on weekends when park user . and resident populations will be high. This is not consistent with the L -1 district's Purpose and Intent "...to provide areas for low intensity, non - nuisance generating in terms of odor, air and water pollution, noise, vibration and glare industrial activities." (RMC 4- 712(A)). No existing solid waste transfer station operates more than 8 a.m. to 5:00 p.m. Standard Time, with a one -half hour later closing during Daylight Savings Time (Attachment B). The 4 • • proposed operations hours are thus excessively beyond the existing norm. More reasonable operating hours would be the same week day hours as other transfer stations and a one hour later opening time on weekends to recognize nearby residential areas. 3. Need to Revise Noise Impact Analysis The method of evaluating project noise generation with State, Renton and Tukwila noise regulations is fatally flawed. Impacts were evaluated based on the distance of the generator from sound level measurement stations (DEIS Pg. 3 -20) instead of from the generator to the closest point of the receiving property as described in WAC 173.60.040(1) and TMC 8.22.030. Only State and Tukwila regulations are being cited since Renton's noise ordinance standards are the same (DEIS Pg. 3 -19). Evaluating noise impacts based on the distance between generator and closest boundary of receiving property results in much shorter distances, less sound reduction, and significant violations of. State and local noise ordinances. Sample locations have been evaluated in table below with locations illustrated in the following figures. The table demonstrates that "Maximum permissible sound levels" (WAC 173.60.040 and TMC 8.22.040) are violated by the proposed use over in almost all categories at Foster Golf Course, and adjacent industrial properties by between 4 and 18 dBA. Maximum permissible sound levels at Ft. Dent Park are only projected to be violated by the top pick operation. The extent of non - compliance with adopted noise regulations is illustrated by noting that in 12 of 20 noise categories, the proposed use exceeds the maximum permissible noise levels. The median level of non - compliance is 8 dBA. It should be noted that impulsive sounds are generated by workers dropping scrap metal into a metal container outside the transfer building, backup alarms on vehicles, and full containers being stacked outside the transfer building. Such sounds are noted in the DEIS to: "...reach 80 -90 dBA at a distance of 100 feet. These near instantaneous levels are not of sufficient duration or frequency to significantly affect compliance with standards..." (DEIS Pg. 3 -24) Safety beepers and several classes of impulsive noise generation are exempt from the above noise standards. However, the State specifically gave local governments the authority to regulate them through their nuisance ordinances (WAC 173 -60 -060). 5 SOUND GENERATORS Waste reduction center @ 100 ft. from main truck doors1.

Dent (Regional) Park (see Table 1). Truck beeper impacts were not included in the analysis. The impacts on other residential, commercial and industrial receiving bodies should also be evaluated in this light. All noise impacts should be fully mitigated to satisfy the "Maximum permissible noise levels" standard since uses in the L -1 zone are to be: "...non- nuisance generating in terms of odor, air, water pollution, noise vibration and glare industrial activities." (RMC 4- 31- 11(A)). 4. Need to Monitor and Remove Pollutants in Storm Water Runoff Prior to Entering the Wetland and Duwamish River. Pollutants including, but not limited to, hazardous particulates blown from truck dumpsters, on tires, and from rail road containers; and typical auto - oriented pollutants, will likely settle on paved surfaces outside the tipping building and be washed down through the biofiltration system, into the wetland, and thence to the Duwamish River. This impact must be recognized and the effectiveness of the proposed mitigation monitored. At a minimum, this should include: a. pre - development soil sampling at the biofiltration swale site, water /soil sampling and a plant /animal baseline inventory at the wetland, b. semi- annual sampling /monitoring of the biofiltration and wetland areas for changes to the baseline for the first two years of operation, c. annual sampling /monitoring after two years for the life of the project if no impacts are noted within the first two year sampling period. Any adverse impacts should be immediately mitigated and semi- annual monitoring instituted thereafter for a two year period. 5. Need to Clearly Delineate Wetland Boundaries and Regulations. The wetland delineated in the EIS is not consistent with data submitted to Tukwila from the wetland consultants (Parametrix), wetland boundary flags found in two field visits by the Tukwila staff biologist, and air photos. Accurate delineation of the wetland prior to any illegal filling is needed to determine the 6 • • extent of restoration (see Violations) and extent of allowed development. At the very least, biofiltration swales must be moved out of existing wetland areas, and Tukwila storm water standards must be satisfied. This could result in significant changes to the site plan since all site drainage would run through this wetland (see Storm Water). CONCLUSIONS Based on the above findings the following is concluded: A. A reasonable environmental baseline of existing conditions has not been provided in the EIS due to illegal filling of the site and wetlands and unknown restoration measures to be required in resolving the violations; B. A reasonable presentation of the existing regulatory structure has not been presented since the proposed use is more reasonably located in the H -1 zone and Tukwila's regulatory requirements have not been addressed. C. The proposed action has not been adequately described since i. significant site design elements such as biofiltration and detention facilities must be relocated which could affect the location of truck circulation and container stacking areas and; ii. the proposed action violates maximum noise standards which may cause significant building redesign and site planning. D. Additional noise and storm water impact analysis is needed since the existing analysis fails to address probable environmental impacts. E. The cumulative impact of the above analyses, the methodological flaws in the analyses, and failure to evaluate probable impacts to noise and storm water quality, and long -term violations by the applicant make re- evaluation of the project in a supplemental EIS the only reasonable course. RECOMMENDATION The City of Tukwila recommends the following actions: 1. The existing EIS and Mitigating document be determined as inadequate based on the above Findings and Conclusions, 7 • • 2. Further SEPA review be suspended until violations are resolved so that an accurate "existing" site conditions can be established, 3. All significant project modifications be incorporated in any future SEPA review to provide an accurate presentation of the proposed action, and 4. Future impact analyses more clearly address regulations. This is especially the case for noise and hazardous materials in storm runoff.

This concern was reviewed in the EIS that was prepared for the Rabanco /Black River project. After completing the review of the project and the EIS, we do not feel that this project is likely to have an adverse impact on water quality. The CDL material will be dumped, sorted and placed in containers within an enclosed building. In accordance with City of Renton Codes and standards, the floor drains of this building will be tightlined into the sanitary sewer system. The containers that the CDL material is placed in, after being sorted and compacted, will be removed from the building and placed on railroad cars. The doors, located at one end of the containers, have seals which are water tight and the containers, which have open tops, will be covered with a tarp when they are removed from the building. It would be unlikely that a significant quantity of fluids would leak from these containers. The EIS found that the proposed stormwater system would be able to remove the minor amounts of CDL leachate from the stormwater that the proposed operation could generate. The EIS stated that leachates generated by the types of demolition debris wastes to be handled in this facility are generally not as toxic as those generated by municipal waste streams. It also noted that the proposed stormwater management facilities are designed to be very effective in removing the typical urban pollutants expected at this site. It has been shown in many surface water quality studies (most notably the National Urban Runoff Program 1983) that individual stormwater management facilities will significantly reduce pollutant Toads in urban runoff. These studies found that the most common facility characteristics that significantly reduce pollution are the following: iarge ratio of pond volume and surface- area -to- drainage -area size, wetpond design, multi - celled of baffled structures, multiple in -line structures and long residence times. Although the stormwater management facilities final design has not been completed, draft design for this project incorporates all of these pollution- reducing characteristics. The draft EIS stated that the design demonstrated that the first flush of stormwater runoff from impervious areas would first enter oil /water separators (either coalescing plat or baffle- type), then flow into a three - celled water quality wetpond. From there stormwater would flow into a detention pond (the wetpond and detention pond may be combined), then into a constructed wetland bio- filtration swale. From the swale the water would flow into the wetland. It should be noted that the final stormwater management system would need to be designed in accordance with the King County Surfacater-De • - •::111 .r is has been adopted both by the City of Renton and King County.

Donald K Erickson, AICP Zoning Administrator mitdcltr 200 Mill Avenue South - Renton, Washington 98055 MITIGATION DOCUMENT RABANCO /BLACK RIVER CDL RECYCLING AND TRANSFER STATION The Environmental Review Committee for the City of Renton issued a Final Environmental Impact Statement for the Black River CDL Recycling and Transfer Station on August 21, 1991. The EIS for this project has identified a number of possible mitigation measures for adverse environmental impacts that were considered to be significant or potentially significant (as defined by quantitative measures whenever such measures were found to exist). These measures, and others which the responsible official may determine are warranted to protect the environment, are the subject of this mitigation document. A number of chapters of WAC 197 -11 speak directly to the imposition of mitigation measures. The relevant chapters are cited below. WAC 197 -11 -060 Content of Environmental Review states that agencies shall "carefully consider the range of probable impacts, including short-term and long -term effects." Impacts shall include "those that are likely to arise or exist over the lifetime of a proposal" or, in some cases, even longer. WAC 197 -11 -330 Threshold Determination Process requires the responsible official to take into account the following when determining whether a proposal has significant adverse impacts: "The same proposal may have significant adverse impact in one location but not in another location;" "the absolute quantitative effects of a proposal are also important and may result in a significant adverse impact regardless of the nature of the existing environment," and "Several marginal impacts when considered together may result in a significant adverse impact." In reaching such a decision, SEPA states that the responsible official shall not balance whether the beneficial aspects of a proposal outweigh its adverse impacts, but rather shall consider whether a proposal has any probable significant adverse environmental impacts under the rules stated above. WAC 197 - 11-448 Relationship of EIS to other considerations. (1) SEPA contemplates .that the general welfare, social, economic, and other requirements and essential considerations-of state policy will be taken into account in weighing and balancing alternatives and in making final decisions.... The EIS provides a basis upon which the responsible agency and officials can make the balancing judgement mandated by SEPA, because it provides information on the environmental costs and impacts. WAC 197 -11 -768 defines mitigation as: 1) avoiding the impact altogether by not taking a certain action or parts of an action; 2) minimizing impacts by limiting the degree or magnitude of the action and its implementation, by using appropriate technology, or by taking affirmative steps to avoid or reduce impacts; 3) rectifying the impact by repairing, rehabilitating, or restoring the affected environment; 4) reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action; and 5) compensating for the impact by replacing enhancing, or providing substitute resources or environments, and /or monitoring the impact and taking appropriate corrective measures. WAC 197 - 11-660 further states that decisionmakers may impose mitigation measures designed to mitigate the environmental impacts subject to the following limitations: A) mitigation measures, or denials, shall be based on policies, plans, rules or regulations formally designated by the agency; B) mitigation measures shall be related to specific adverse environmental impacts clearly identified in an environmental document on the proposal and shall be stated in writing by the decisionmaker; C) mitigation measures shall be reasonable and capable of being accomplished; D) responsibility for implementing mitigation measures may be imposed upon an applicant only to the extent attributable to the identified averse impacts of its proposal. Voluntary additional mitigation measures may occur; E) before requiring mitigation measures, agencies shall consider whether 1 local, state or federal requirements and enforcement would mitigate an identified significant impact; and F) to deny a proposal under SEPA, an agency must find that: 1) the proposal would be likely to result in significant adverse environmental impacts identified in a final or supplemental environmental impact statement prepared under this chapter; and 2) reasonable mitigation measures are insufficient to mitigate the identified impact. In imposing mitigating measures, the Environmental Review Committee considered environmental impacts that are expected from the project itself. In addition, several other independent projects are undergoing or have recently undergone environmental review in the same geographical area. These include the Metro Wastewater Treatment Plant Expansion, the Rabanco Recycling Facility, and Phase VI of the Black River Corporate Park. The cumulative impacts of these other projects have been considered in the formulation of this mitigation document, and will be or have been considered in the mitigation documents of these other projects during their environmental review. SEPA states that: "After its decision each agency shall make available to the public a document that states the decisions. The document shall state the mitigation measures, if any, that will be implemented as part of the decisions, including any monitoring of environmental impacts." (WAC 197- 11- 660(1)(b)). This document is intended to meet this requirement. As well as analyzing the environmental impacts, the City of Renton, under its land use provisions, must assess its many objectives and goals and decide how this project furthers or conflicts with them. Some City goals may be internally conflicting. When this occurs, the City believes that the SEPA process mandates a close environmental analysis to determine priorities. If the priorities are established and the project is able to mitigate its impacts sufficiently, then the City believes it should proceed. This document presents mitigation measures necessary for the ultimate construction of the Black River CDL Recycling and Transfer Station. THE PROPOSAL The Rabanco Regional Landfill Company (RRLC) proposes constructing and operating a recycling and transfer station for construction and demolition debris, and incidental, mixed Toads of Iandclearing debris. Discrete loads of Iandclearing debris (including mud and dirt) and yard waste will be hauled to other specialized facilities, such as Cedar Hills composting facility. The proposed recycling and transfer facility would be constructed on a 13.5 acre site in the City of Renton. At full operation, up to approximately 90,000 cubic yards per month of construction, demolition, and Iandclearing (CDL) waste would be processed. After recyclables are extracted, the remaining waste would be transferred to the Roosevelt Regional Landfill in Klickitat County, Washington. The proposed facility could be initially scaled down for processing smaller volumes (approximately 40,000 cubic yards per month) of CDL debris. Gradually, the facility could be expanded to process the larger volumes of waste. Analysis in the EIS is based on handling the larger waste volume. Reducing the amount of CDL debris processed at the proposed facility would not reduce the size of any of the proposed structures. One of the primary objectives of the proposal is to provide a specialized recycling facility for CDL waste. The proposed facility would provide the means for processing CDL waste in an economically sound manner. In processing CDL waste, the Rabanco Regional Landfill Company would be allowed to recapture concrete, wood, metal, and other materials currently valuable on the recycling market. The material to be recycled will be shipped to the recycling market in trucks. These truck trips have been included in the 808 truck trips per day that the project is anticipated to generate. PURPOSE AND NEED In 1990, King County's solid waste system handled approximately 148,000 tons of CDL waste. The closure of the Newcastle Landfill in January 1990 and the Mt. Olivet Landfill in August 1990 were followed by an emergency public rule (Put -7 -1), issued by the King County Board of Supervisors, 2 revising the waste acceptance policy for CDL waste at County solid waste facilities. With this new policy, there are three disposal options for non - recycled CDL waste generated in King County: (1) the Hidden Valley Landfill in Pierce County, (2) the Morrison Sand and Gravel disposal facility in Kitsap County, (3) and the King County Transfer Station (from where waste is transferred to a permanent disposal site). The Hidden Valley Landfill is scheduled to close by November 31, 1991, and the Morrison Sand and Gravel facility has little remaining capacity. One of the objectives in the King County Comprehensive Solid Waste Management Plan (CSWMP) is to reduce to the maximum extent possible the amount of solid waste requiring disposal: The CSWMP recommends that the County select and contract with a vendor to plan and permit one or more new facilities for disposal and potential recycling of landclearing and demolition waste. More recently, this waste stream has been termed construction, demolition, and landclearing debris (CDL). On December 10, 1990, the Environmental Review Committee issued a Determination of Significance for the Black River CDL Recycling and Transfer Station project. A Draft EIS (issued June 17, 1991) and Final EIS (issued August 21, 1991) were prepared for this project. The content of the EIS was determined by the Lead Agency (in this case, the City of Renton) based, in part, on key sections of the SEPA rules (197 -11 -402, 408, 430, and 440) together with results of the EIS scoping process. The Draft Black River CDL Recycling and Transfer Station EIS included an analysis of the proposed action and a no action alternative. The Final EIS responded to the comments received by the City of Renton on the Draft EIS. This document has been prepared as a summary of the mitigation measures contained in the Draft and Final EIS and also provides the time periods in which the mitigation measures must be completed. ELEMENTS OF THE ENVIRONMENT A. EARTH SOILS In general the upper soil horizon (from 0 to 10 feet) consists of medium -dense fill composed of sandy gravel. This overlays a 20 to 30 -foot layer of fill consisting of a soft medium -stiff, sandy, clayey silt. The soft clayey silt appears to be a result of deposits from former settling ponds. In the northern part of the site, below the sandy, clayey silt, is a native material consisting mostly of hard silty sandstone. In the southern part of the site, the sandy clayey silt is generally underlain by a medium -dense silty sand. Upper soil layers would be affected as excavation and paving occur. Most of the proposed structures would be located atop soft clay and silt. These soils have a high moisture content and would tend to settle over time as water slowly drains from them. The rate of soil settlement would increase as pressure is exerted from the structure's concrete floor slabs and foundations, container storage slabs, driveways, and paved working areas. Estimates of settlements are about 1 to 2 feet. Impacts to soils caused by erosion should be insignificant because the site slopes are relatively mild. Along steeper slopes, erosion impacts could be minimized by following standard mitigation practices. TOPOGRAPHY The majority of the site is flat to gently sloping. On the eastern and southeastern edge of the site, the slope drops quickly from a flat -lying area (adjacent to 68th Avenue South) to an area of lower elevation. This drop forms an approximately 22.5 degree bank along much of the eastern boundary. The highest elevation is approximately 75 feet (at the top of bank) while the lowest elevation of the site is approximately 26 feet. The site is currently undeveloped. Most development of the proposed Transfer Station would occur on relatively level surface and would not significantly affect topography. Most grading and excavation would occur on the low -lying elevations of the site during preparation of the construction of the main building and container storage area. 3 RECOMMENDATION: 1) The applicant shall, in order to minimize erosion, have a certified geotech engineer prepare an erosion control plan, prior to the issuance of any site preparation /building permits; such a plan should include, but not be limited to, the installation of such items as: a) water - diversion berms, b) swales, c) permanent benches, d) a sturdy vegetative cover, e) the use of erosion control matting on slopes until a vegetation cover is established; and f) the installation of temporary plastic covering along all exposed slopes. This plan shall be prepared to the satisfaction of the Department of Planning /Building /Public Works. The temporary erosion control measures shall be maintained throughout the construction phase of the project and until the permanent erosion control measures are fully established and landscaped to the satisfaction of the Department of Building /Planning /Public Works. The permanent erosion control measures shall be maintained for the life of this project. 2) The applicant shall, in order to ensure that the soils are drained properly and that the drainage meets City of Renton water quality standards, develop plans for a drainage system to consolidate underlying soft soils in advance of construction. These plans shall be developed to the satisfaction of the Storm Water Utility Section and implemented prior to the construction of the permanent buildings on the project site. POLICY NEXUS King County Surface Water Design Manual; City of Renton Comprehensive Plan I.G., I.M.2., VI.A., VIII.C.; Mining, Excavation, & Grading Ordinance (4 -10); Environmental Review Ordinance (4-6); WAC 197 -11 -768. SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS Based on the soils analysis prepared by Rittenhouse -Zeman and Associates it appears that soil settlement would be the primary impact associated with the proposal. Recommended mitigation measures would allow the proposal to avoid significant adverse impacts. B. AIR Air quality impacts can result from traffic and from on -site emissions both during the construction phase and the operation of the proposed development. The Puget Sound Air Pollution Control Agency is responsible for controlling stationary sources of air pollution in the central Puget Sound region, while WSDOE is responsible for monitoring carbon monoxide (CO) levels. None of the monitoring sites for either of these agencies are close enough to the study area to be considered representative of the CO concentrations in the project area. Given the current density of land use development and the existing roadway network, existing violations of the CO standards are considered unlikely in the immediate vicinity of the project area. The applicant will be asked, to ensure that the proposed project does not have a significant impact on the.air quality, to provide a dust control system within the building and to use electric - powered vehicles whenever feasible. 4 RECOMMENDATIONS: 3) The applicant shall, in order to limit impacts to air quality from operations occurring within the building, install a dust control system that meets current State and Federal standards for recycling centers. Design plans for this system shall be; a) submitted to the satisfaction of the Development Services Division, b) prepared with the building permit application, and c) installed prior to the issuance of occupancy permits. The dust control system shall be maintained for the life of the project. 4) The applicant shall, in order to limit impacts to air quality and to reduce potential noise impacts from operations outside of the building, use electric - powered yard equipment (e.g. yard goat) where feasible. Prior to the issuance of building permits, the applicant shall present to the City of Renton a list of the yard equipment indicating which ones shall be battery powered and the means of propulsion for the remainder. 5) The applicant shall, in order to limit impacts to air quality from the operation of the wood chipper, limit the wood to be processed through the wood chipper to non - painted and untreated woods. 6) The applicant shall, in order to limit the potential adverse impacts to air quality, water quality, and soil, provide a material handling plan for materials that may be hazardous (e.g. asbestos, pesticides, oils) to the satisfaction of the Development Services Division prior to the issuance of occupancy permits. POLICY NEXUS Environmental Review Ordinance (4 -6); City of Renton, Comprehensive Plan I.B., VI.A.1.; WAC 197 -11 -768. SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS No significant unavoidable adverse impacts would be expected. C. WATER SURFACE WATER AND RUNOFF /ABSORPTION The EIS stated that expected pollutants from the site under existing conditions are sediment and some urban pollutants. The concentrations of sediment in runoff from the site are probably quite high, because most of the site is gravel or exposed, unstable soil. Only a small portion of the site is vegetated. The EIS reports that the proposed site layout would increase the impervious area from 0.6 to 10.6 acres. Because the existing fill areas, sedimentation ponds, and railroad grade are not highly permeable, the difference in absorption rates between pre- and post - development surfaces and the corresponding increases in runoff rates are not large. The pre - development 2- and 10 -year runoff rates of 4.4 and 8.4 cfs, respectively, would increase to 6.6 and 10.5 cfs, respectively, after development of the proposed project. SURFACE WATER QUALITY The EIS notes that the overall existing drainage pattern toward the 30 -inch pipe on the north end of the site would remain the same. Most of the site would be covered by impervious surfaces, which would stabilize disturbed soils and gravel and reduce the concentration of sediment in runoff from the site. The applicant will need to develop a storm water system that is in compliance with the King County Surface Water Design Manual, as adopted by the City of Renton. 5 FLOODING Although no surface waters occur on the project site, there is a wetlands area located at the discharge pipe under the railroad. This wetland is hydrologically connected to the Green River during high flows in the river. Panel numbers 326D and 328D of the Flood Insurance Rate Map (FEMA 1989) for the site indicate that the portion of the site on which construction will occur lies in Zone "C ". Zone C is an area of minimal flooding and is not considered to be in the 100 -year floodplain. However, the wetland area does lie below the 100 -year flood elevation of the river and would be subject to flooding during the occurrence of the 100 -year flood on the Green River. No activity is proposed on the site at elevations presently below the 100 -year flood elevation. Construction plans must indicate the delineation of the 100 -year flood elevation. GROUNDWATER A major portion of the site would be covered by Impervious surface (pavement or buildings). The EIS states that any precipitation that would contact wastes would be collected and treated as runoff instead of being recharged directly into the groundwater. A stormwater management facility would be designed to include multi - celled ponds and other in -line treatment structures to retard discharge runoff and reduce pollutants. Because the CDL materials would be processed within an enclosed building and stored in closed containers, precipitation is not expected, under normal circumstances, to directly contact wastes. Some contact by rainfall is unavoidable. However, the EIS states that leachates generated by the types of demolition debris waste to be handled in this facility are generally not as toxic as those generated by municipal and hazardous waste streams. The storm water from the site will also be treated in a biofiltration system prior to its release off -site. RECOMMENDATIONS: 7) The applicant shall mail a notice to all CDL debris trucking firms that discrete loads of hazardous materials (e.g. hazardous waste, pesticides, asbestos) will not be accepted at the Black River facility. Appropriate signage shall also be located at the entrance to the project site. The notice to be mailed shall also contain a list of acceptable materials. A copy of this notice shall be submitted to the Development Services Division prior to the issuance of occupancy permits. The applicant shall, in order to protect the water quality at the project site, refuse entry to any trucks carrying discrete loads of hazardous materials or discrete Toads of asbestos. Trucks that are refused entry shall be directed to other appropriate transfer sites. The applicant shall have a minimum of one employee specially trained to identify hazardous materials and asbestos debris on -duty at all times that the facility is in operation. The applicant shall, as a portion of the project site (where the wetland is located) is located within the 100 -year flood plain, as identified on the FEMA maps, provide an agreement to the satisfaction of the City Attomey, and submitted prior to the issuance of occupancy permits, to hold the City harmless from any claims which may result due to damage occurring to the subject property as the result of flooding of the subject property. POLICY NEXUS Renton Storm and Surface Water Drainage Ordinance (4 -22); King County Surface Water Design Manual; Environmental Review Ordinance (4-6); Comprehensive Plan I.A., I.C., I.G., I.H., I.I.; Green River Valley Plan I.C.4. 6 SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS - NONE If the draft stormwater management system plan is incorporated into the design of the proposed facility, no unavoidable adverse impacts to surface water resources would occur. The configuration of the stormwater management system may be modified during the development of the project's final design and construction plan. A revised stormwater management system that meets the standards of the King County Surface Water Design Manual would mitigate anticipated adverse impacts. No significant unavoidable adverse impacts to groundwater resources beneath the site would be expected. D. PLANTS AND ANIMALS WETLANDS AND VEGETATION Site plans, aerial photos, soil survey maps and reports were reviewed in the preparation of the EIS to identify potential wetlands on the property. King County soil maps (Snyder et al. 1973), Hydric Soils of the United States (U.S.D.A. 1987; SCS 1987), and a Soil Conservation Service report (1989) provided information on wetland soils. The property was visited and vegetation, soil, and hydrology were examined for wetland characteristics using the Federal Manual for Identifying and Delineating Jurisdictional Wetlands. The EIS identified a small, natural wetland along the northern edge of the property. Separated from the wetlands by a dike is an old sedimentation basin once used in connection with the gravel pit operation located across the road (68th Ave. S /Monster Road). The wetland and the old sedimentation basin are connected by a culvert. Another culvert beneath the railroad tracks connects the wetlands to the Duwamish River. Both the existing sedimentation basin and the wetlands are characterized by a willow - dominated shrub community with a reed canarygrass and cattail - dominated emergent community. WILDLIFE AND HABITAT The EIS notes that the project site is highly disturbed and is surrounded by a mix of industrial and residential uses. The site has a history of being used for top soil and gravel mining, multiple sedimentation ponds for gravel washing and stormwater control, and storage of fill material and heavy equipment. Although the EIS did not discover the presence of soil contamination, the use of this site for the storage of heavy equipment in the past does indicate that the potential for soil contamination does exist. Should contaminated soils be discovered during the construction phase of the project the applicant will need to provide a remediation plan. The contamination shall be mitigated prior to continuing the construction of the project. Habitat quality ranges from nonexistent on the compacted fill area to moderate on the adjacent forested hillside. Wildlife using the site can be expected to include a high proportion of urban- adapted native and non - native species such as American Crow, house sparrow, rock dove, house mouse, raccoon, and "opossum. There are no known threatened, endangered, or sensitive animals on the site, and the EIS indicates that none are likely to occur because the site is highly disturbed and has poor habitat quality. A nesting colony of great blue herons is located approximately 0.6 miles east of the project site and about 300 meters north of Oakesdale Avenue. This site is protected from noise generated at the project site by the intervening hillside. FISHERIES The EIS identified the Duwamish River as the only watercourse that could be affected by the proposed development. The river flows north to Elliot Bay through a highly urbanized basin, flanked by high density residential and industrial development. The King County 7 Reconnaissance Report #26, June 1987, noted that "the discharge of oils and other toxicants from thousands of acres of industrial land and the dumping of domestic garbage (common though illegal) have produced serious water quality problems ". The Duwamish River provides passage to upstream spawning areas for returning coho, Chinook, and chum salmon. The location of the proposed recycling facility is upland, more than 400 feet east of the Duwamish River, and is separated by a raised railroad bed. The applicant will be required to provide a water quality management system to ensure that this facility does not negatively impact the Duwamish River. RECOMMENDATIONS: 10) The applicant shall, in order to ensure that the surface water quality is not negatively impacted by this project, install a stormwater water management system (retention /detention system), prior to initiating any grading, filling, or construction, so that runoff from the impermeable surface would flow into the wetland area at the north end of the site at approximately the same rate as before the installation of the transfer station. This system shall be installed prior to the issuance of any occupancy permits and maintained for the life of the project. 11) The applicant shall, in order to ensure that future operations do not negatively impact the existing wetland, provide a twenty -five foot (25') landscaped buffer around the existing wetland. Landscaping plans for this buffer shall be submitted to the satisfaction of the Development Services Division prior to the issuance of Building Permit applications and be fully installed prior to the issuance of any occupancy permits. 12) The applicant shall, in order to mitigate the Toss of vegetation and wildlife habitat that has occurred on this site, establish a wildlife habitat area on the project site equal to two percent (2 %) of the project site. Plans for the wildlife habitat area shall be submitted to the satisfaction of the Development Services Division with the Building Permit application and fully planted prior to the issuance of occupancy permits. 13) The applicant shall, in order to improve the quality of the existing wetland and to minimize the potential adverse impacts to water quality, provide vegetation enhancement within the existing wetland to the satisfaction of the Development Services Division. Plans for the wetlands enhancement shall be submitted prior to the issuance of Building Permits and all work shall be completed prior to the issuance of occupancy permits. 14) The applicant shall, in order to ensure the survival of the wetland enhancement vegetation, buffer zone plantings and wildlife habitat area, develop a comprehensive . plan for monitoring and assuring successful preservation of the wetland, protection of water quality, and restoration of wildlife habitat to the satisfaction of the Development Services Division. This plan shall include visits by a qualified wetlands ecologist, hired by the applicant and approved by the City, at 6 months, 1 year, 2 years and 3 years following project installation to verify success of preservation and revegatation efforts. Copies of the reports from the wetlands ecologist shall be submitted to the Development Planning Section and the owner of this facility. If any of the plantings within the buffer area or wetlands are found to be in need of replacement during these inspections, the report shall include the modifications of designs and /or re- planting of the dead or dying plant materials and the time period in which these efforts will occur. This report shall be submitted to the satisfaction of the Development Services Division. The comprehensive monitoring plan shall be submitted to the satisfaction of the Development Services Division prior to the issuance of building permits. All cost associated with the monitoring program and any re- planting of the wetlands and buffer areas shall be borne by the facility owner, lessees, assignees or successors in interest. 8 POLICY NEXUS Environmental Review Ordinance (4-6); Comprehensive Plan I.A., I.C., I.D., I.E.., I.J.; Green River Valley Plan I.C.B. SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS - NONE The proposal would avoid significant adverse impacts to wetlands, vegetation and fisheries with the provision of the mitigation measures identified above. The loss of the existing low quality wildlife habitat on site will be off-set by the provision of a high quality wildlife habitat equal to 2% of the project site area. E. NOISE IMPACTS OF OPERATIONS ACTIVITIES The noise generated at the proposed Black River facilities can be expected to be similar to the types of noise generated at the existing facility at Third and Lander Streets in Seattle. Sound level measurements, by TRC Environmental Consultants, found the dozer, front -end loader, and trucks to be the primary noise sources at the site. Trucks generated noise when backing up the ramp and when retying their engines while dumping at the existing facility. The clanging of doors occasionally also generated an impulsive noise from the trucks. At the proposed Black River facility these activities would occur within an enclosed building. The noise generated by the front -end loader and the dozer would occur when they were sorting and compacting the CDL debris. This activity would occur within the enclosed building. The applicant has also proposed to install a wood grinder in this facility. Similar grinders at other facilities were found by TRC to generate a noise level of 74 dBA at 100 feet. The grinder would be installed in the building and enclosed on three sides by an acoustical block wall which should reduce the noise levels outside of the building to the Code - required standards (65 dBA at the property line). A final source of noise generated at this site would be the arrival of and departure of trains three times per week. The peak noise level of the train is predicted by TRC to be 84 dBA when measured at 100 feet from the source. The train would only add 0.1 dBA to the daily average equivalent sound level. This increase in ambient sound levels would be negligible. NOISE IMPACTS ON SURROUNDING AREAS Noise impacts associated with the proposed facility would be reduced by several factors: distance, atmospheric attenuation, and intervening terrain. The EIS found that noise levels at the sensitive receptors (e.g. heron rockery, apartments, single- family residential areas, recreation areas) would fall within acceptable ranges. TRUCK NOISE IMPACTS The EIS used the existing CDL debris facility at Third and Lander to determine the potential noise impacts of trucks at the proposed Black River facility. To evaluate potential changes in traffic noise due to trucks serving the waste recycling facility, an FHWA (U.S. Federal Highway Administration) traffic noise model was employed within the EIS. As noted above the model found that noise generated by the trucks would fall within acceptable ranges at the sensitive receptors. However, the EIS stated that the noise increase along Oakesdale Ave. would be significant but that the noise level at the heron rockery would not be adversely impacted due to the distance from the roadway to the heron rockery. 9 RECOMMENDATIONS: 15) The applicant shall, in order to reduce the noise impacts on surrounding areas, limit operations to between 7 am and 8 pm Monday through Friday and 8 am to 6 pm on Saturday. The facilities shall be closed on Sunday and National Holidays. The applicant shall discourage truckers from letting their truck engines idle outside of the project site before the gates are opened. The applicant shall locate a sign at the entrance gate with the hours of operation and requiring all trucks arriving early to shut off their engines. The applicant shall provide an agreement, acceptable in form to the City Attorney, limiting the hours of operation to the satisfaction of the Development Services Division prior to the issuance of occupancy permits. 16) The applicant shall, in order to reduce noise levels at the project boundaries, incorporate the following design features into the proposed facility: a) limitation of most transfer operations (e.g. dumping and sorting of debris, filling of containers) to inside of the processing building, Only the necessary movement of containers shall occur outside of the building, b) enclosure of the tipping floor, sorting area, and all material container loading areas within the building, and c) location of the wood chipper within the main building in an area enclosed on three sides by an acoustical block wall that extends up to a minimum of two feet over the height of any motor or a minimum of six feet, the open side of this area shall be oriented away from the residential area to the north and west. The opening of the enclosure around the wood chipper shall be directed away from all doors or openings leading to the exterior of the building. 17) The applicant shall, in order to reduce noise impacts from vehicles, provide an agreement to minimize noise from back -up beepers in a manner that complies with state and federal regulations. The applicant shall provide this agreement to the satisfaction of the Development Services Division and in a form acceptable to the City Attorney prior to the issuance of occupancy permits. 18) The applicant shall, in order to educate their staff and users of the facility on the potential noise impacts and the affects on surrounding properties, develop an annual training program (e.g. shutting equipment down instead of letting it idle for long periods of time, on -site noise sources) for their own on -site personnel and hand outs for truck drivers. This training program must be approved by the Development Services Division prior to the issuance of occupancy permits. 19) The applicant shall, in order to ensure that the noise reduction techniques applied to the project are effective, deposit $25,000.00 in an escrow account to cover the cost of noise monitoring to be conducted within six months of the start of the operation of the facility. This account will only be used by the City of Renton to complete the noise monitoring study. Any unused funds will be returned to the applicant within one year of the issuance of occupancy permits. The applicant shall also provide the City with a surety device for $75,000.00 which the City of Renton may use to provide additional noise attenuation methods off -site identified by the required noise study. The applicant shall install additional noise attenuation within six months of the completion of the noise monitoring study. If the surety device is not used by the City of Renton it shall be released by the City within 2 years from the date of the completion of the noise study. 20) The applicant shall, in order to reduce noise impacts to nearby residential areas, restrict outdoor construction activities to weekdays between the hours of 7 a.m. and 8 p.m. and 8 a.m. to 6 p.m. on Saturdays with no construction to occur on Sundays or holidays. 10 21) The applicant shall, in order to reduce noise impacts, ensure that all construction equipment has sound control devices no less effective than those provided on original equipment (e.g. equipment mufflers and noise shrouds are intact and operational). 22) The applicant shall, in order to control noise, provide a noise education program for operators of construction equipment and haul trucks. The program shall discourage wide open throttles, compression release brakes, and provide incentives for operators using noise suppression methods (Le. shutting off equipment when not in use). 23) The applicant shall, in order to reduce noise and vibration impacts on nearby wildlife habitat (e.g. wetland area at north end of project site, Green and Duwamish Rivers) and on area residents, ensure that auger cast -in -place piling construction is used in lieu of conventional pile driving where soil conditions allow for cast -in -place pilings. In areas where the applicant can demonstrate to the City's satisfaction that cast -in -place pilings are not feasible, the applicant shall use the construction method which will produce the least amount of noise and vibration. POLICY NEXUS Comprehensive Plan I.B., VI.A.; Green River Valley Plan I.B., I.C.3; Environmental Review Ordinance (4-6). SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS There will be a significant increase in traffic noise on Oakesdale Parkway between the recycling facilities and South Grady Way. The EIS notes that due to the distance between the roadway and the heron rookery the noise generated by the truck traffic will be lower than the existing background noise level within the rookery. F. LAND AND SHORELINES ZONING The proposal is an allowed use in the L -1 zoning district (Light Industrial), and the site design complies with the L -1 district's relevant development standards. The L -1 District allows for the manufacturing, processing, assembling of articles, products or merchandise. The City of Renton has determined that the correct terminology for the recycling and transfer station product servicing since it is not a manufacturing use. The proposed use primarily processes products or merchandise from previously prepared natural or synthetic materials. The zoning on the land surrounding the project site is for Tight and /or heavy industry, allowing uses similar to and compatible with the proposal. Fort Dent Park and the Foster Golf Links are located across the river from the subject property. The proposed recycling and transfer facility includes a variety of design features (e.g. landscaping, color scheme, building design) intended to ensure that the proposed facility is compatible with these recreational land uses. LAND -USE PLANS AND POLICIES The applicant will need to improve water and sewer service to the project site. In order to accomplish this task the applicant has proposed to attach a water and a sewer line to the Monster Road Bridge. Any constructions that occurs within 200 feet of a shore line is regulated by the Shoreline Master Program. 11 RECOMMENDATION: No special mitigation measures required beyond the Code- required standards. SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS - NONE Significant adverse impacts can be avoided with the mitigation discussed above. G. AESTHETICS The proposed facility lies on the northeast edge of the Duwamish River valley floor. Immediately northeast the valley wall rises to a height of several hundred feet above the valley floor. The opposite valley wall also rises several hundred feet above the valley floor, and lies about 0.33 miles southwest of the site. On the southwest side, the site is bordered by the Burlington Northern and Union Pacific tracks. These tracks run the length of the valley on a 5- to 20- foot -high berm. As shown on the photos included in the EIS, the project would be at least partially visible from Fort Dent Park, Foster Golf Links, the residential areas on the hillsides and the adjacent roadway. There is also the concern that dirt, dust, and debris could blow out of the uncovered trucks on the way to or leaving this development. Requiring the trucks to cover their loads will reduce the potential for this impact to occur. The applicant will also need to develop agreements with the local governments in the area to provide funding for the additional cleaning of the streets used to access the proposed facility. RECOMMENDATIONS: 24) The applicant shall, in order to reduce the apparent visual mass of the building, paint the facility shades of earthen tones (e.g. green and /or brown as identified in the EIS) including both its walls and roof. Building color shall be varied in color and tone to reduce its apparent mass. Medium, low- reflective tone values should be used. The applicant shall submit color samples and a color scheme to the satisfaction of the Development Planning Section prior to the issuance of building permits. 25) The applicant shall, in order to improve the aesthetic appearance of the project site, submit a detailed landscape plan to the Development Planning Section prior to the issuance of building permits and be .approved prior to the issuance of occupancy permits. This plan shall include but not be limited to the following: a) An irrigated landscape strip along 68th Street South (Monster Road) a minimum of fifteen (15) feet in width. A combination of deciduous and evergreen trees and shrubs shall be used within this area. b) Landscaping along the westerly border of the project site and in islands adjacent to the southern, western, and northern face of the building, except where it would interfere with the safe loading and movement of the railroad cars or the movement of equipment on site. Planting areas shall be a minimum of ten (10) feet in width and contain a mix of evergreen trees (minimum of 8 feet in height) and shrubs (minimum of five gallons in size). c) All garbage and /or refuse dumpster areas shall be visually screened by an opaque fence, landscaping or some combination thereof. 12 d) Landscaping shall include a mix of deciduous and evergreen trees and shrubs in order to provide screening of the site all year. Deciduous trees shall be a minimum of 2" in diameter, evergreen trees shall be a minimum of eight feet in height, and shrubs shall be a minimum of five gallons in size. e) To ensure maintenance of the proposed landscaping a surety device equal to ten percent (10 %) of the value of the landscaping and valid for three years from the date the landscaping is installed shall be provided to the City of Renton prior to the issuance of occupancy permits. If the applicant receives written permission from the City of Renton to delay the installation of the landscape materials, the surety device may also be delayed until the landscape has been completed. 26) The applicant shall, in order to reduce the potential for litter or dust blowing from the site, ensure that all paved surfaces are washed down or cleaned at least daily, up to four times daily if conditions warrant it, that all landscaped areas are cleaned daily to remove litter /debris, and that all storage containers are properly covered by a tarp or other suitable secure device. The applicant shall deposit $50,000 into an escrow account that the City of Renton may draw against for on -site trash removal. The applicant shall prepare an agreement to the satisfaction of the City Attorney allowing the City of Renton to inspect the facility and if the applicant does not provide the remedial action recommended by the City within 30 days to reimburse the City for all expenses incurred for the required clean -up. The escrow account and the agreement shall be provided to the City of Renton prior to the issuance of occupancy permits. 27) The applicant shall, in order to reduce the amount of litter or other light CDL debris that may blow out of trucks, require that all trucks hauling any CDL debris onto, or off of the project site are properly covered. Trucks that do not have covers would be refused access to the facilities. 28) The applicant shall, in order to reduce the potential for debris blowing out of trucks, develop a program that includes but is not necessarily limited to training programs for haulers to convince haulers to properly cover their Toads with tarps, fines for trucks with improperly covered Toads or other methods that prevent litter blow -out. The applicant will also keep a list of the flagrant abusers and if the fines prove ineffective (over 12 violations in a 12 month period), ban the hauler from use of the Black River facility for 12 months. The fines collected shall be used to reimburse the City of Renton for clean up required along City roads. 29) The applicant shall, prior to the issuance of building permits, develop agreements with the City of Renton, City of Tukwila and King County to cover the cost of extraordinary services required to remove litter, CDL debris and dirt from roadsides due to this project. The cost of these agreements will be passed on to the individual truck drivers arriving with uncovered or improperly covered loads in the way of an extra fee or fine. Note: In the case of a dispute between the applicant and another jurisdiction on the wording or dollar value of this agreement, the City of Renton as lead agency would be the final arbitrator. 30) The applicant shall, in order to reduce the visual aspect of the project as seen from the west, develop measures to reduce the amount of activity on the western border of the site, nearest Foster Golf Links. Prior to the issuance of building permits the applicant shall redesign the building to orient the loading bays so that they open to the south. The applicant may orient a maximum of one loading bay towards the west if the applicant can demonstrate to the satisfaction of the Development Services Division that it would be infeasible to orient the bay in any other direction. 13 31) The applicant shall, in order to reduce the potential impacts from light and glare to surrounding land uses, ensure that all on -site lighting is located and shielded to contain all visible glare on -site. The type, intensity, height, and location of lighting standards to be installed on the project site shall be indicated on the landscape plans. These plans shall be submitted to the satisfaction of the Development Services Division prior to the issuance of site preparation /building permits. NOTE TO APPLICANT The applicant must, prior to the erection of any signs on the project site, submit sign permit applications for all proposed signs under the City's Sign Ordinance. POLICY NEXUS Landscaping Ordinance (4- 31 -34); Environmental Review Ordinance (4-6); Comprehensive Plan l.A., I.E., III.C., III.D., VI.A, VI.B.; Green River Valley Plan I.B., I.C.3. SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS - NONE Significant adverse impacts can be avoided with the mitigations measures discussed above. However, until the vegetative screen, recommended above, has developed, views from the golf course will be impacted by the proposed structure. Significant adverse visual impacts could develop if CDL debris were allowed to build -up along the roads leading to the facility or on the subject property. Compliance with the mitigation measures listed above should limit the potential adverse visual impacts. H. TRANSPORTATION STREET NETWORK The EIS states that the majority of truck trips generated by the facility would originate from south and east King County because of an existing recycling facility that serves the demands generated in Seattle to the north. However, there appears to be no guarantee that over the life of the proposed facility that routes might not change, that the possible closure of existing facilities or shifts in the anticipated markets would not alter the proposed routes. Most trucks will exit Interstate 405, Interstate 5, and Highway 167, and follow the existing street network to the site. TRAFFIC VOLUMES AND OPERATION The EIS indicates that based upon the forecasted maximum volumes of waste and the most likely average load size, this facility is expected to accommodate up to 808 trips per day involving a full range of container -type trucks. This translates into approximately 404 trips in and 404 trips out. The 10 to 20 employees on -site are expected to generate an average of up to 60 vehicle trips per day. HEAVY TRUCK TRAFFIC /ROAD SURFACES As the majority of trips generated by the proposed project will be trucks, the City is concerned with the potential cumulative impacts to road surfaces and bridges that this and nearby projects could generate. Some of the routes that could potentially be used by trucks accessing the project site are located outside of the City of Renton in the City of Tukwila and the King County area. The applicant will need to enter into agreements with the adjacent jurisdictions as well as the City of Renton to mitigate potential adverse impact to existing and new roadways used as routes to and from the proposed facility. The EIS also noted that the line of sight distance at the entrance /exit of the project site could be a potential problem. Signalization of this intersection would reduce the potential for accidents occurring in this area. 14 RECOMMENDATIONS: 32) The applicant shall, in order to ensure that the routes used by the trucks accessing the project site are not adversely impacted, provide a proposed truck routes map to the satisfaction of the Development Services Division and the Transportation Systems Division prior to the issuance of building permits. This map shall indicate the routes trucks will use from the roads included in the proposed Truck Routes Ordinance to the project site. The applicant shall encourage all truck drivers to adhere to the prescribed routes which have been designed and constructed to handle trucks. Copies of this map shall be mailed, on a semi - annual schedule, to the hauling firms and handed to the truck drivers to reinforce the use of designated truck routes. 33) The applicant shall, in order to mitigate potential adverse impacts to the road surface and bridges, sign an agreement with the City of Renton, prior to the issuance of building permits, which allows the City to recover costs associated with unusual wear and tear to road surfaces including bridge deck surfaces. The methodology of the agreement shall be as follows: S = (A) X (0.2) [(C' - C) / DJ X (Truck Ratio) Where: S = The proportion of the total cost attributable to a given project or development (i.e. The Black River Recycle and Transfer Center). A = Cost of the overlay (One inch of overlay plus prelevel and preparation work). C' = Measured change in pavement condition rating (PCR) during the survey period. PCR at beginning of monitoring period - PCR at the end of the monitoring period. C = Normal change in PCR for the same time period. Determined by monitoring PCR conditions one year prior to opening (Would likely range between 5 and 15 points per year). D = Typical overlay life in years. Truck Ratio = Projected Generated Traffic (PGT) divided by Average Daily Truck Traffic .(ADT) times the number of days the project is operational, plus Project Generated Traffic. The cost of the analysis described above shall be borne by the applicant. 34) The applicant shall, in order to mitigate impacts to the streets within the City of Tukwila, sign an agreement with the City of Tukwila, prior to the issuance of occupancy permits by the -City of Renton, to provide a one -time fee of $1,000.00 per peak -hour trip expected to be generated by the project through the intersection of Interurban Avenue /Grady Way and West Valley Highway /South. 156th Street provided that the applicant has reviewed and verified the basis for the fair share calculations. 35) The applicant shall, in order to reduce the potential for accidents occurring at the entrance to the project site, install a signal device or other traffic control devices deemed appropriate by the Transportation Systems Division. Any required traffic safety device or signal shall be installed prior to the issuance of occupancy permits unless a deferral is obtained from the City of Renton Board of Public Works. 15 36) The applicant shall, in order to reduce the number of potential vehicle trips generated by this facility, utilize a program, approved by the Development Services Division, to ensure that Toads of recyclable concrete, asphalt, and compostable land clearing waste are diverted to facilities designed to handle these materials. The applicant, shall provide an easement to allow access to the site to allow periodic monitoring of the recycling and transfer activities by City staff. This document is to be submitted in a form acceptable to the City Attorney and shall be duly recorded with King County prior to the issuance of building permits. Trucks carrying discrete Toads of these materials shall be denied entrance into the recycling building. Acceptance of discrete Toads of these materials at the Black River facilities shall constitute grounds for closure of the facility until further environmental review of the expanded operation. 37) The applicant shall, in order to reduce the adverse impact potential of additional truck trips generated by the removal of CDL waste from the project site by trucks in the event that rail service is temporarily suspended (30 days or less), provide a Backup Transfer Option Plan to the satisfaction of the Transportation Systems Division prior to the issuance of occupancy permits. This plan shall discuss the backup system of transferring waste materials from the project site to the landfill in the advent that rail service is temporarily discontinued. The plan also needs to discuss methods to ensure that the number of vehicle trips per day do not exceed the levels reviewed in the EIS. 38) The applicant shall, in order to mitigate the impacts to the Monster Road Bridge, the existing structure south of the development, sign an agreement to pay a proportional share of the cost of replacing a three lane bridge. The proportional share shall be determined by dividing the equivalent axle Toads generated by Rabanco by the equivalent axle Toads generated by all trucks and heavy vehicles crossing the bridge. The agreement shall be submitted to the satisfaction of the Transportation Systems Division and in a form acceptable to the City Attorney. The signed agreement shall be submitted to the City prior to the issuance of building permits. Payment of the proportional share shall be made by January 1, 1993 or within one year after granting of an occupancy permit, whichever occurs first. The equivalent axle loads shall be determined by a combination of actual weight, where available, and by classification counts. The cost of the bridge replacement shall be as estimated by the Transportation System Division. Notes to Applicant The project is limited to a maximum of 808 truck trips per day and 90,000 cubic yards of CDL debris per month as identified in the EIS. If, at any future time, the applicant or future owners /lessees desire to expand beyond this level of development, the additional information would be included in an addendum to the EIS, or in other separate environmental documentation depending on the significance of environmental issues raised by the new information and the extent to which the range of possible impacts is addressed in this EIS. The applicant is encouraged to enter into agreements for the maintenance and repair of roads used by haulers to access the proposed recycling and transfer station with the City of Tukwila and King County prior to the issuance of occupancy permits. POLICY NEXUS Environmental Review Ordinance (4-6); Six -year Street Plan; Street and Arterial Plan; Comprehensive Plan I.B., VI.A., VII; Green River Valley Plan I.C.S. 16 SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS With the mitigation measures described above, potentially significant adverse impacts to traffic volume and safety, road surfaces, Monster Road bridge, and rail traffic could be avoided. The increase of _noise along Oakesdale Ave. by approximately 7 dBA is a significant adverse impact. This increase in noise is not expected to have an adverse impact on adjacent commercial buildings, area residents, or the heron rookery due to the distance between the road and the rockery and existing ambient background noise levels in the area. I. PUBLIC SERVICES AND UTILITIES PARKS AND RECREATION Two heavily -used recreational facilities, the Foster Golf Links and Fort Dent Park, are located west and south of the project site, respectively. The City of Renton proposed Master Trails Plan and proposed Comprehensive Park and Recreation Master Plan indicate that bicycling and pedestrian hiking trails shall be constructed in this area. The applicant will also need to provide on -site recreation opportunities for employees (e.g. showers, a half - basketball court) and is encouraged to make a voluntary contribution to the Parks Department to off-set potential impacts to area wide recreational facilities prior to the issuance of occupancy permits. FIRE PROTECTION The City of Renton Fire Prevention Bureau has noted that the project is in a location that exceeds the 4- minute maximum response time for Aid service and a 5- minute maximum response time for Fire assistance. The proposed facility is located in a response area of over 7- minutes. According to the Grading Schedule for Municipal Fire Protection issued by the Insurance Office, fire stations should be located within 1 1/2 miles of the proposed development. The closest existing fire station is located 2.8 miles from the proposed development. Staff are therefore recommending that the applicant contribute towards the cost of constructing a new fire station in this area. SANITARY SEWER SERVICES The EIS indicates that the project will not have a significant adverse impact of sanitary sewer service. The applicant will need to extend existing sewer lines to the project site in compliance with City Codes and standards. WATER SERVICE The EIS indicates that the project will not have a significant adverse impact on water service. The applicant will, however, need to extend water lines to the project site in compliance with City Codes and standards. RECOMMENDATIONS: 39) The applicant shall, in order to mitigate on -site recreational impacts, provide revised drawings prior to the issuance of building permits showing shower . facilities and recreational facilities (e.g. a half - basketball court) on the project site. The applicant is encouraged to make a voluntary contribution to the City of Renton, Community Services Department funds to off -set the project impacts to area recreational facilities. 41) The applicant shall review the proposed Master Trails Plan with the Community Services Department and the applicant is encouraged to incorporate the trail plans into the site design. 17 42) The applicant shall, in order to reduce the emergency vehicle response time, execute an agreement with the City of Renton Fire Department to provide a fair - share of the cost to construct a fire station in the Green River Valley area. This agreement shall be provided to the satisfaction of the City Fire Department and the City Attorney prior to the issuance of building permits.

SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS No significant adverse impacts to recreational facilities or City utility services are expected. J. HISTORIC AND CULTURAL RESOURCES The EIS reviewed the potential for adverse impacts to cultural and historic resources by the development of the proposed project. The Cultural Resources Assessment, dated April 2, 1991, was prepared by Larson Anthropological /Archaeological Services. As part of this assessment the Muckleshoot Tribe was contacted by phone and by letter. Although the proposed site is in an area that has been the scene of an ethnohistoric Indian population followed by a number of historic activities, no archaeological sites or culturally significant historic structures were identified after a careful check of records and field inspections. RECOMMENDATION: 43) The applicant shall, in order to prevent adverse impacts to historic and /or cultural resources, if cultural resources are identified during subsurface excavations associated with project construction, halt all construction in an area large enough to maintain integrity of the resources and hire a professional archaeologist to monitor all operations and shall notify the State Office of Archaeology and Historic Preservation and the Development Services Division. Construction activities shall not resume until written approval from the City of Renton and the State Office of Archaeology and Historic Preservation is received by the applicant. POLICY NEXUS Comprehensive Plan I.F., IX.E.; Environmental Review Ordinance (4-6). SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS Unidentified buried cultural resources could be adversely affected by the construction activities. However, measures will be taken to document and preserve any such artifacts unearthed. K. HAZARDOUS MATERIALS The applicant does not propose to handle the storage or transfer of discrete loads of hazardous materials as part of the proposed development. However, there is a potential for hazardous materials to be included in Toads of CDL debris. 18 RECOMMENDATIONS: 44) The applicant shall prepare and provide the City of Renton with a restrictive covenant on the property stating that the proposed development will not be used as a transfer station for hazardous waste materials. This agreement shall be submitted to the satisfaction of the Development Services Division and the City Attorney prior to the issuance of occupancy permits. 45) The applicant shall, in order to ensure that hazardous materials (e.g. asbestos, hazardous waste, pesticides) have a minimum of one employee, on the dumping floor at all times, specially trained to identify and supervise the handling Note to the Applicant All hazardous materials shall be stored in containers approved for their storage and shall be shipped from the project site on carriers approved for shipping hazardous materials. POLICY NEXUS Environmental Review Ordinance (4-6); Comprehensive Plan I.B., I.M., VI.A.; Green River Valley Plan I.B.

REVIEW AND LICENSING A number of mitigation measures have been established for this project to ensure that it does not adversely impact the environment or area residential development. In order to ensure that this measures are effective, a monitoring program has been proposed. This monitoring program will allow the City to evaluate the effectiveness the mitigation measures and identify any additional measures that could be required. The City will also be issuing a license for this business. If the applicant does not comply with any of the proposed mitigation measures or operates this facility in a manner that is not acceptable to the City of Renton, than the license could be revoked. 46) The applicant shall provide a covenant and easements requiring it, future purchasers, assignees, successors in interest or lessees, to allow the City of Renton to annually review the proposed development's performance in landscape maintenance, noise mitigation, litter control, street cleaning, air quality, wet lands, control of waste stream, hauling limitations and traffic mitigation. The cost of this program shall be borne by the applicant and the annual fee for the services provided by the City of Renton shall be set at 150% of the City's total expenditure in these areas during the previous year plus the cost of the annual performance monitoring. The total expenditure would include, but not be limited to, Code inspections, monitoring programs and physical activities (e.g. street sweeping). These covenants and easements shall be approved by the City Attorney and the Development Services Division prior to issuance of any site preparation /building permits. The monitoring program will be initiated one year from the date of the issuance of occupancy permits and shall remain in effect for the life of the project . unless both the City and the applicant mutually agree that a particular element is no longer required. This monitoring program shall include all other monitoring requirements discussed in this mitigation document. The covenant and easement shall be submitted in a form acceptable to the City Attorney. 19 47) The applicant shall obtain from the City of Renton an annual license to operate the proposed facility. This license shall be renewed annually upon completion of the annual monitoring program if, in the City's opinion, the operator of the facility has complied with all of the mitigation measures and requirements. Denial of the annual license shall be cause for requiring the facility to be closed until remedial actions have been completed to the satisfaction of the Development Services Division. The cost of the annual license shall be borne by the applicant, future owners, lessees, assignees, or successors in interest. - POLICY NEXUS Environmental Review Ordinance (4-6); WAC 197 -11 -768; Comprehensive Plan I.B., LC, I.D., I.E., I.G., III.C., VI.; Green River Valley Plan I.B., I.C.

WASHINGTON 98188 MEMORANDUM PHONE 8 (2061433-1800 Gary L. VanDnsen, Mayor To: John McFarland, City Administrator Office of the Mayor From: Vernon Umetsu, Associate Planner ;Or Department of Community Development Date: October 24, 1991 RE: Rabanco -- Planning Division Comments on Lynn Guttmann Letter to John McFarland of October 16, 1991. The following constitute Planning Division comments on the Lynn Guttmann letter to John McFarland date 1/16/91. 1. Zoning Interpretation Appeal An administrative interpretation was made by Renton in a letter to Rabanco on March 13, 1990 (Guttmann, 10 /16 /91:p.1,par.2). An appeal of that decision had to be filed by March 27, 1990 per the Renton Municipal Code. This interpretation letter was transmitted to Tukwila as an appendix to the original environmental checklist on approximately August 17, 1990 -- our first knowledge of the administrative interpretation. Therefore, we are precluded from filing an appeal of that interpretation through the administrative appeal process. 2. DCD Environmental Considerations A. Description of Alternatives: Tukwila staff appreciate the additional elevations and cross - sections to be sent and look forward to reviewing them. B. Air - Issues acceptably resolved. C. Water Issues acceptably resolved for Planning although Public Works should be consulted. • • There is still a question on the appropriate level of detention. Renton maintains that detention per the King County Surface Water Control Manual of 1990 is the 2 and 10 year event for 24 hours plus 30 percent per Sec. 1.2.3 -3 (John Hobson, Renton Public Works Engineering, 10/23/91). Ross Heller of our staff maintains that the King County Manual requires detention for the 10 and 25 year event for 24 hours. This seems to be essentially a local Renton issue with no Tukwila impacts. D. Plants and Animals On -Site Wetland Status: Renton has ducked the issue of whether this is an "associated or adjacent wetland ". Their understanding that a Duwamish River connection via a 30 inch pipe can be automatically disregarded is incorrect. The basis for these designations is whether the wetland is affected by the Duwamish River waters regardless of the mechanism. The hydraulic link could be a pipe, a ditch, a canal or some other mechanism. Proximity and distance between wetland and river are also important factors in this determination. The Corps of Engineers and DOE should be consulted for a determination of status especially due to the salt water influence at this stretch of river. Unauthorized Wetland Filling: As stated previously, information from a site visit by Tukwila staff strongly suggests that the wetland mapped in the EIS has been significantly filled and previous aerial photos show a much larger, forested wetland in the northern site. DOE's lack of response does not mean that no unauthorized fill has occurred since they do not have adequate baseline data, staff, or direct jurisdiction. The more appropriate agency would be King County B.A.L.D. since they have local jurisdiction on this portion of the site, a reasonably comprehensive wetland inventory, and more available staff than DOE to help ensure adequate review. The Corps of Engineers may also have jurisdiction based on their determination of wetland status as . discussed above. E. Noise Chipper Acoustical Buffer Wall: The 12 foot acoustical wall, or a minimum six feet higher and longer than the wood chipper along any face directly in line with a north or south opening, will limit the spilling of sound over and around the barrier to the outside with impacts to the Tukwila golf course and King County regional park. A two foot buffer would not be sufficient to significantly limit this spillover impact. A more specific quantification of each wall alternative to mitigate spillage of chipper noise could be established through a noise study. • • An alternative to any north -south acoustic wall could be the installation of acoustical doors on all openings and a commitment to keep doors shut when not actually accommodating vehicle or person passage. Provision should be made for personal access without opening vehicle doors. Truck Beeper: A review of Washington safety regulations with the State Dept. of Labor and Industrial Relations indicates that disabling back -up beepers on a temporary basis is prohibited. WAC 296 -24- 073 -6(A) prohibits the interference with the operation of any safety device without a variance (Rhiemer, L.I.R., 10/23/91). Thus, much higher levels of back -up beeper impacts than initially estimated can be expected. Extending building walls and roof so that all backing will be done in a semi - enclosed space could help reduce this impact on the regional golf course and park. Assuming a 50 ft. turning radius, 65 ft. truck length, and no maneuvering in parking spaces, this would mean a semi - enclosed space approximately 120 feet deep. Western Acoustical Doors: Any reasonable acoustical door will have a significant mitigating affect on noise impacts when they are closed. A commitment to have these doors closed when not actually in use would be sufficient to resolve Tukwila's concern's on this issue. F. Aesthetics Building Design: Tukwila staff look forward to reviewing the proposed final building design with Renton staff. The balance of large stature landscaping and building design would be appropriately finalized at that time. Landscaping: The additional five feet would provide enough space to stagger large evergreen trees in a triangular pattern approximately 20 -25 ft. apart. This would give the perception of depth and minimize uplifting of adjacent pavement. It is possible that this space would not be needed with the planting of large stature evergreen trees adjacent to the building as has been continually requested, and architectural modifications to reduce perceived building mass. 3. SEPA Appeal The EIS and mitigation document can be appealed on the basis that either or both inadequately address the impacts of the proposal. Such an appeal is denovo to the Hearing Examiner with substantial weight given to Renton's SEPA Responsible Official. Appeals from the Hearing Examiner decision are to the City Council and based on the record, with no public hearing (RMC 4 -8- 411 110 16(D)). If "...the Council determines that a substantial error in fact or law exists in the record, it may remand the proceeding to Examiner for reconsideration, or modify, or reverse the decision of the Examiner accordingly." (RMC 4- 8- 16(F)) Whatever issues we raise, our burden of proof is significantly more than that of the Responsible Official. Because of this, our chances of success are significantly reduced on issues which can be reduced to a matter or interpretation such as whether the visual building mass has been adequately screened or noise sufficiently attenuated. We may argue strenuously that the zoning conformance is an issue in the adequacy challenge. However, that challenge is likely to be unsuccessful because that very issue is covered in the administrative appeal process discussed earlier -- and is not by its very nature, an issue of SEPA as defined in WAC 197 -11. Procedurally we are realistically foreclosed from this specific challenge unless Fred Kauffman, the Renton Hearing Examiner, turns very liberal on us. Even so, the Renton City Council may be more conservative, given their record of reviewing his decisions. cc: Berry /Beeler /Pace /file. file:rab10.24 CITY OF TUKWILA 6200 SOUTHCENTER BOULEVARD, TUKWILA, WASHINGTON 98188 September 25, 1991 PHONE # (2061433 -1800 Gary L.

VanDusen, Mayor This letter represents the City of Tukwila's comments on the subject Draft E.I.S. As you know, I am keenly interested in this project and its impacts on Tukwila citizens. Our comments on the DEIS are preceded by the comments made in a March 29 letter from Rhonda Berry of my staff. New comments are differentiated from the original comments by bold print. These written comments supplement the comments made at the public hearings on June 5 and June 13. Page No. Comment Summary ix. Concern over traffic impacts on Tukwila roads should also be expressed (i.e. not only Renton roads). PROJECT DESCRIPTION 1 -5 Need site plan and elevation figures to show dimensions of structures, container stacks, etc. There should also be an air photo of the site with the property lines and project improvements outlined. 1 -7 The two story employee center is not apparent on the site plan. DEIS COMMENT: The above are still needed for an adequate project description. In addition, Figure 1-4 must be dimensional and raises more questions than it answers. The six westerly loading bays are a feature not shown in previous drawings. This results in much more westerly activity and severely limits the possibility for aesthetic impact mitigation (see Aesthetics). 1 -7 Hours of operation are only cited as being 6 - 8 on weekdays and 8 - 8 on Saturdays. Sunday closure is only implied and should be explicitly stated if this is the case. Any holiday closures should also be identified. DEIS COMMENT: No Tukwila response needed. No further clarification is given. We can therefore rely on the facility being closed on Sundays, but open on all holidays on a normal schedule. Impacts of this schedule are discussed under each subject area. Ms. Lynn Guttman June 17, 1991 Page 2 1 -7 Is the 10 -truck queuing area sufficient? The experience of other landfills on peak queuing should be reviewed to substantiate this. DEIS COMMENT: No Tukwila response needed. No further clarification is given. No further comment is appropriate since all impacts would affect Renton. 3 -27 The openings on the north and south for containers . and trucks should be shown on elevations. The existing textual reference does not describe these openings. DEIS COMMENT: No Tukwila response needed. New data shows that there are no north -south openings. All openings are on the east and west. EARTH 3 -2 There has been no analysis of off -site dust control on site access roads or entrainment of possibly hazardous demolition dust in storm runoff systems. Off -site dirt control on access roads is a significant enough problem to have required daily road cleaning at the Newcastle CDLC landfill. Mitigating measures to control dust could also include mandatory debris wet down and tarp cover, with inspection by Rabanco staff prior to dumping; an initial informational program of fliers for those haulers whose loads are too dry or uncovered; and escalating fines for repeat offenders to be administered at the site. There is also the need to assess the impacts of lead, mercury, and other hazardous contaminants which may be present in demolition debris from older structures. The adequacy of the proposed sediment and biofiltration systems to keep expected hazardous demolition debris from entering the Duwamish River or ground water table needs to be assessed before any determination of impact significance can be made. 3 -9 An analysis of the needed cleaning of demolition debris from storm runoff before it enters the Duwamish River or ground water table needs to be completed as discussed above. DEIS COMMENT: NOISE 3- 19/C -6 The DEIS addresses storm water management facilities as being designed to be very effective at removing the "typical urban pollutants" expected at the site. Pollutants at the site have the potential for being other than typical, and the storm water system design should consider the potential pollutants and corrections so they do not reach the Duwamish or ground water. Maximum noise impacts may occur at Tukwila's Foster Golf Links, approximately 300 ft. across the open, hard surfaced railroad right of way, and at King County's Fort Dent Park, approximately 500 feet to the southwest. Existing noise levels should be field measured and impacts then evaluated at these sites. It is not reasonable to use a measurement at SLM 7 (Pg. 3 -20 and 21) where industrial noise levels dominate, to represent all westerly areas since the golf and park areas should be expected to have much lower noise levels. Ms. Lynn Guttman June 17, 1991 Page 3 • • The significance of noise impacts in golf and park areas should be evaluated based on effects on normal conversation levels as discussed in the Tukwila Attachment A. 3 -19 Is one of the "L -25 "'s supposed to be "L -2.5" in Table 3.5 -1? 3 -24 Foster Golf Links is located immediately across the hard surfaced railroad right of way (approximately 300 feet); not 400 feet across a river and associated soft/buffering vegetation. This is correctly shown in Figure 3.6 -1, page 3 -29. 3 -24 & 25 DEIS COMMENT: It is inappropriate to imply that the receiving golf course environment could be treated as an industrial area merely because it is zoned R -A (Agricultural) in order to be a legally conforming use per Tukwila Municipal Code 18.10.020(7). It is our feeling that EPA guidelines are not meant to be so literally applied and that this statement should be removed. In Table 3.5 -1, page 3 -20, the Leq maximum noise standard for residential areas should be changed to 60 day and 50 night from 62 and 52 respectively (TMC 8.22.050 and WAC 173 -60 -040). This should also be reflected in page 3 -20 paragraph 1. (Page 3 -20) It is appropriate to clarify that while daytime construction noise is not subject to a specific standard, it is subject to regulation as a nuisance pursuant to WAC 173 -60 -060 and per Tukwila Code TMC 8.22.120, and night time construction noise is limited to 50 Leq on residential areas by both the State (WAC 173 -60 -040) and Tukwila (TMC 8.22.040 and 050) between 10 p.m. and 7 a.m. Additional noise studies were done for Foster Golf Course and Fort Dent Park (pages 3 -20 through 3 -24). An analysis of the results show two potential Tukwila impact areas of concern: a. The calculated top pick (container loading equipment) generates 56 to 57 dBA at the Foster Golf Course site. The top pick would exceed maximum noise standards adopted by the State (WAC 173 -60 -040) and Tukwila (TMC 8.22.040- 050) during the hours and 6 a.m. to 7 a.m., which happen to be one of the busiest times for the course during golfing season. A mitigating measure would be to limit top pick operations to the hours of 7 a.m. to 8 p.m. when it would be in compliance with all noise standards. b. (Page 3 -24) It is incorrect to say that truck backing beepers are "...near - instantaneous...and are not of sufficient duration of frequency to significantly affect compliance with standards..." These backing sounds could register 77 dBA at Foster and 66 dBA at Fort Dent Park. The cumulative impacts of 800+ truck backing operations per day is very significant due to the volume increase and the sound's piercing quality. Mitigation would include ensuring that all backing operations are done in areas which buffer the Golf Course and Ft. Dent Park with concrete walls and sound deadening roofs. Ms. Lynn Guttman June 17, 1991 Page 4 The listed mitigating measures on page 3 -30 are all important to minimizing noise. However, there is no commitment to implement these measures. They should either be required, enforceable under specific circumstances, or not included since there is not assurance of implementation. Pulsing, piercing noise impacts from truck backup beepers on Foster Golf Course and Fort Dent Park must be included as a Significant Unavoidable Adverse Impact in the absence of additional assured mitigation. A final concern relative to noise is the impact of sudden, loud noises whose dBA levels cannot be measured. Examples include crashing of truck gates, dropping of large pieces of metal, as well as other types of demolition debris. This type of noise can be more annoying than others that have been referenced in the DEIS. 3 -26 It is not clear why there is a 4.5 dBA reduction for each doubling of distance. What is the initial distance required (i.e. would a doubling of an initia120 foot distance to 40 feet result in a 4.5 dBA reduction)? DEIS COMMENT: No comment -- the basis was explained. LAND AND SHORELINE USE 3 -32 The rendering plant referenced under "Tukwila Comprehensive Plan" is a legally non- conforming use. Such a use is not generally allowed in a light industrial zone. DEIS COMMENT: No comment required. This reference was deleted. AESTHETICS 3 -35 The extent of visual impact should be quantified. For instance, the "...upper part of the main processing building" being visible should be better quantified as the upper "X" feet of the main processing building. 3 -36 Mitigating measures should be specific actions which the reviewer is assured will be taken. If there is a question on a measure's implementation, then it should not be considered since the reviewer cannot rely upon it to have any effect on an ultimate evaluation of significant unavoidable adverse impacts. The minimum landscape mitigating measures to screen the general site, break up the visual impact of large paved areas, and soften building masses would include the following: A mix of fast and moderate growing large stature evergreen trees to mix with the very fast growing poplar; large stature (8 feet high) evergreen shrubs to form a perimeter screen from the golf course and park, the shrub screen to be set behind a three tiered mix of deciduous and coniferous plantings; and all planted areas to be automatically irrigated and protected from equipment damage. A conceptual landscaping plan with species and planting sizes should be provided at a level of detail shown in the project site plan. 3 -38 Project views from Fort Dent Park should also be provided. • • Ms. Lynn Guttman June 17, 1991 Page 5 3 -40 The tentative nature of potential mitigating actions makes the conclusion of no significant impacts very questionable. The suggested modified mitigating measures would allow a more realistic comparison of impacts and mitigating actions, and make any final conclusions much more valid. DEIS COMMENT: The additional view analyses requested have been provided. DEIS COMMENT: (Page 3 -44). It is not explained why plantings at Foster Golf Course would result in a more effective vegetative screen for the project in a much shorter time than on site plantings as is normally required. A review of the site plan shows many opportunities for not only on site plantings, but plantings of large stature evergreen trees adjacent to the structures where they would be most effective in breaking up the large wall masses. SEPA guidelines usually require mitigation to be done on the project site, as should be the case here. Tukwila's Parks and Recreation Director is, at this time, not amenable to plantings on the Golf Course property. As you might imagine, sunlight is essential for grass growth especially on tee and greens areas, and any additional plantings on the course would provide more shaded areas and unacceptably inhibit growth. Section 3.8 of the DEIS addresses transportation issues. Although the project's peak hour traffic volumes generated will not make a measurable difference in the service level at Interurban /Grady Way or at West Valley Highway /S. 156th Street, they will further degrade traffic flow. The existing level of service is F, and the improvements will cost over $11,000,000. A Black River proportionate share of those costs based on traffic volume increase, as we use with other developments, would be unfair due to the high cost of this improvement. The trip fee approach has been used with other developments generating traffic in the interchange, and we feel that the Black River development should be treated similarly. That is, a mitigation fee of $1,000 per peak hour trip would be assessed for use in funding the planned capacity improvements. The Black River development $1,000 /trip would be for: Interurban/Grady southbound lefts increase 5 eastbound throughs increase 29 westbound lefts increase 8 Total 42 W. Valley Hwy /South 156th St. eastbound lefts 34 southbound rights 7 Total - 41 This is computed based on the DEIS a.m. peak hour data, which provides volume projection but proposes no mitigation for its affect on the Interurban/I -405 interchange. A final concern of mine is wetlands. A wetland is shown in Figure 1 -3, but it does not seem to correspond to what I found on a visit to the site. It is also evident that some wetland filling has taken place over a period of some years. I would like to know how the filling was done, who performed the filling, was the City of Renton aware of this filling, and were proper permits obtained? e • Ms. Lynn Guttman June 17, 1991 Page 6 I'd like to take the opportunity to commend you and your staff on your efforts to get public input on this project. The public hearing on June 13 in the Tukwila City Council Chambers made it possible for some of our citizens to participate who may not have taken the time to come to Renton City Hall or the put their comments in writing.

Copies are available for review at the Renton Municipal Library and in the Development Services Division, Renton Municipal Building located at 200 Mill Avenue South, Renton, Washington 98055. PROPOSAL: Construction and operation of a recycling and transfer station for construction and demolition debris, and incidental, mixed loads of landclearing debris (CDL debris). Discrete loads of landclearing debris (including mud and dirt) and yard waste will be hauled to other specialized facilities, such as the Cedar Hills composting facility. The project would consist of several structures. These structures include a main processing and recycling building (covering approximately 60,000 square feet), two smaller buildings (each covering 1,500 square feet) for equipment repair and maintenance, and employee /administrative services, and two container storage areas of approximately 5,000 to 7,500 square feet each. The tallest portion of the main structure would be approximately 50 feet above the finish grade at the front (east side) of the building. At full operation, up to approximately 90,000 cubic yards per month of construction, demolition, and land clearing debris would be processed. The proposed facility could be initially scaled down for processing smailer volumes (approximately 40,000 cubic yards per month) of CDL debris. Up to 808 one -way truck trips and 60 one -way auto trips per day will be generated. Highest project travel volumes (70% of all project - related traffic) will occur between 11:00 a.m. and 3:00 p.m. The proposed facility is intended to be part of a larger regional approach to managing CDL waste in King County. Based on the goals of the King County Solid Waste Management Plan, recycling will play a major role in reducing total volumes in the waste stream.

Hansen, Manager King County Solid Waste Division 450 King County Administration Building 500 Fourth Avenue Seattle, WA 98104 RE: Scoping Comments for King County Construction Demolition and Land Clearing Debris Disposal Environmental Impact Statement. Dear Mr. Hansen, The City of Tukwila appreciates the opportunity to provide scoping comments on this E.I.S. I do not have any specific comments on the system wide project without the further data which will be forth coming in your analysis. However, any such review should recognize the need for detailed impact analysis and mitigation prior to issuing any construction permits. Tukwila's general scoping comments focus on the status of this E.I.S.; with specific comments on the proposed Rabanco Renton transfer station impacts on traffic, noise, aesthetics, and water quality are presented below. General Comments on E.I.S Status I have the following understanding of this E.I.S. process from discussion between our staffs: a. The County will be conducting only a very general analysis of project impacts for the purpose of selecting a vendor. b. This SEPA process is being done under "Phased Review" (WAC 197 -11- 060(5)). This is to allow additional, detailed SEPA review on specific sites. c. Final vendor approval will not be given until the lead SEPA agency responsible for detailed site specific SEPA review has completed its process and all agencies with jurisdiction have issued their respective permits /approvals. The status of the E.I.S. relative to these and other issues should be clearly specified in the document. Site Specific Comments on the Rabanco Renton Transfer Station a. Traffic Impacts -- The City Engineer (Ron Cameron 433 -0179) requests additional information on off -peak trip distribution. A determination of impact to Tukwila streets and appropriate mitigation measures cannot be made until this further data is supplied. b. Noise Impacts -- Although most operations will be within the building, the size of access openings is not clear, nor are the anticipated noise levels on Fort Dent Park or surrounding residences. Maximum noise levels (Lmax) should be mitigated to a level harmonious with park activities and as consistent with conversation in affected residential =areas. This will be especially important for the high pitched beeping noises associated with reversing vehicles as well as the constant truck rumbling. c. Aesthetic Impacts -- The visual dominance of the building's 45 ft. high by 300 ft. long western building face and stacked containers must be assessed from Fort Dent Park view points just across the Green River, as well as from the upper slopes of Tukwila Hill. Impacts of the visual dominance of these "walls" on these Tukwila areas is potentially significant, and must be evaluated and minimized. d. Water Quality -- The impacts of wash down water and storm runoff. This additional data is essential to the evaluation of project impacts on Tukwila. I look forward to reviewing the D.E.I.S. and hope that the cooperative working relationship between our staffs thus far can be continued throughout this project. Rhonda Berry of the Mayor's staff will be coordinating staff person for Tukwila please feel free td contact her at 433 -1851 if you have any questions. Sincer , L.

VanDusen, Mayor Councilperson Nancy Mathews Council President, City of Renton 200 Mill Ave South Renton, Washington, 98055 Dear Mayor Clymer and Councilperson Mathews: By this letter I am transmitting a formal motion from the City of Tukwila to the City of Renton regarding the proposed location of a construction waste sorting facility in the Black River Quarry area. We have recently learned of the scale and potential impact that the facility will have on both Renton and Tukwila. Of particular concern is the amount of truck traffic that is expected to serve the site. Much of this traffic will use access routes that will involve travel within the City of Tukwila. Additionally, we have an interest in visual, noise, light and air quality impacts. As you know the facility will be visible from the Tukwila Hill area. Our respective staffs have initiated discussions concerning the development review process. By the transmittal of this motion, we are encouraging continued communication and cooperation in studying this very substantial facility. Thank you for your consideration of this matter. Sinc G L.

VanDusen, Mayor RE: Rabanco Black River Waste Recovery Center and Shipping Yard. Dear Mrs. Guttmann, This letter is to clarify and expand on Tukwila's environmental concerns on this project to date, as earlier expressed in various telephone conversations and at the October 15th meeting with Renton and King County staff. Based on the information supplied, Tukwila's concerns focus on traffic, aesthetic, and noise impacts. Traffic Impacts The City Engineer (Ron Cameron 433 -019) requests additional information on off -peak trip distribution. A determination of impact to Tukwila streets and appropriate mitigation measures cannot be made until this further data is supplied. I understand that you are also requesting additional data. Our staff would appreciate a copy of this additional information for review. Aesthetic Impacts The visual dominance of the building's 45 ft. high by 300 ft. long western building face and stacked containers must be assessed from Foster Golf Course and Fort Dent Park view points just across the Green River, as well as from the upper slopes of Tukwila Hill. Impacts of the visual dominance of these "walls" on these Tukwila areas is potentially significant, and must be evaluated and minimized. Please note that a preliminary review of the upper Tukwila Hill viewpoint analysis does not seem to accurately show tipping building dimensions nor does it show the stacked containers. An easy "balloon" analysis would probably be reasonably accurate. • Noise Impacts Although most operations will be within the building, the size of access openings is not clear, nor are the anticipated noise levels on Foster Golf Course, Fort Dent Park or surrounding residences. Maximum noise levels (Lmax) should be mitigated to a level harmonious with park activities and as consistent with conversation in affected residential areas. This will be especially important for the high pitched beeping noises associated with reversing vehicles as well as the constant truck rumbling. This additional data is essential to the evaluation of project impacts on Tukwila and making a threshold determination. I look forward to reviewing this information and working with you in resolving these and any other issues. I especially appreciate your coordinating the Renton /Tukwila /King Co. meeting on October 15th and hope to continue this close coordination in further meetings.

Dear Mr. Hodge: I have been asked to look at your proposed site between 68th Avenue South, the old Union Pacific railroad right -of -way, and the Pacific Coast Railroad right -of -way in the City's L-1 District (Light Industrial). Within this zone "recycling collection stations or centers, provided they are located outside any required laannd caging area" are permitted. A recycling center is defined in Section 4 -31 -2 as: "A collection point for small recyclable items, such as cans, bottles, newspapers, and secondhand goods. Activities shall be limited to sorting, compaction and transferring." Under this definition the proposal would not be allowed. However, as a "product servicing use" (Section 4- 31- 1LB.1. d)) : "Manufactunn'....��, processing, assembling and packaging of articles, Products or from previously prepared natural or synthetic materials" is permitted as a principal use in this zone. It would appear that Rabanco's proposed Demolition and Construction Debris Transfer Center, would, from the project description Mark Wolken and John Hendrickson gave me when we met on Friday, meet this definition. In addition to the land use issues, the proposed project will also have to comply with SEPA. As a bare minimum it will have to go through the City's environmental review process which takes approximately ten (10) weeks to complete, including the fifteen (15) day comment period and fourteen (14) day appeal period. It is likely that traffic impacts of trucks arriving and departing the site will be an issue as also might noise. Surface water and storm water drainage may also need to be addressed in greater detail since the site is near or in a potential floodplain. _ We look forward to assisting you on your proposal if you decide to proceed with it on this site in Renton. If 1, or my staff can be of further assistance please feel free to give me a call M telephone number is 235 -2550. Donald K. Erickson, AICP Chief, Current Planning cc: L.

Erickson, AICP Zoning Administrator mitdc @r 200 Mill Avenue South - Renton, Washington 98055 • • 1 MITIGATION DOCUMENT RABANCO /BLACK RIVER CDL RECYCLING AND TRANSFER STATION The Environmental Review Committee for the City of Renton issued a Final Environmental Impact Statement for the Black River CDL Recycling and Transfer Station on August 21, 1991. The EIS for this project has identified a number of possible mitigation measures .for adverse environmental impacts that were considered to be significant or potentially significant (as defined by quantitative measures whenever such measures were found to exist). These measures, and others which the responsible official may determine are warranted to protect the environment, are the subject of this mitigation document. A number of chapters of WAC 197 -11 speak directly to the imposition of mitigation measures. The relevant chapters are cited below. WAC 197 -11 -060 Content of Environmental Review states that agencies shall "carefully consider the range of probable impacts, including short-term and long -term effects." Impacts shall include "those that are likely to arise or exist over the lifetime of a proposal" or, in some cases, even longer. WAC 197 -11 -330 Threshold Determination Process requires the responsible official to take into account the following when determining whether a proposal has significant adverse impacts: 'The same proposal may have significant adverse impact in one location but not in another location;" "the absolute quantitative effects of a proposal are also important and may result in a significant adverse impact regardless of the nature of the existing environment," and "Several marginal impacts when considered together may result in a significant adverse impact." In reaching such a decision, SEPA states that the responsible official shall not balance whether the beneficial aspects of a proposal outweigh its adverse impacts, but rather shall consider whether a proposal has any probable significant adverse environmental impacts under the rules stated above. WAC 197 - 11-448 Relationship of EIS to other considerations. (1) SEPA contemplates that the general welfare, social, economic, and other requirements and essential considerations .of state policy will be taken into account in weighing and balancing alternatives and in making final decisions.... The EIS provides a basis upon which the responsible agency and officials can make the balancing judgement mandated by SEPA, because it provides information on the environmental costs and impacts. WAC 197 -11 -768 defines mitigation as: 1) avoiding the impact altogether by not taking a certain action or parts of an action; 2) minimizing impacts by limiting the degree or magnitude of the action and its implementation, by using appropriate technology, or by taking affirmative steps to avoid or reduce impacts; 3) rectifying the impact by repairing, rehabilitating, or restoring the affected environment; 4) reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action; and 5) compensating for the impact by replacing enhancing, or providing substitute resources or environments, and /or monitoring the impact and taking appropriate corrective measures. WAC 197 - 11-660 further states that decisionmakers may impose mitigation measures designed to mitigate the environmental impacts subject to the following limitations: A) mitigation measures, or denials, shall be based on policies, plans, rules or regulations formally designated by the agency; B) mitigation measures shall be related to specific adverse environmental impacts clearly identified in an environmental document on the proposal and shall be stated in writing by the decisionmaker; C) mitigation measures shall be reasonable and capable of being accomplished; D) responsibility for implementing mitigation measures may be imposed upon an applicant only to the extent attributable to the identified averse impacts of its proposal. Voluntary additional mitigation measures may occur; E) before requiring mitigation measures, agencies shall consider whether 1 local, state or federal requirements and enforcement would mitigate an identified significant impact; and F) to deny a proposal under SEPA, an agency must find that: 1) the proposal would be likely to result in significant adverse environmental impacts identified in a final or supplemental environmental impact statement prepared under this chapter; and 2) reasonable mitigation measures are insufficient to mitigate the identified impact. In imposing mitigating measures, the Environmental Review Committee considered environmental impacts that are expected from the, project itself. In addition, several other independent projects are undergoing or have recently undergone environmental review in the same geographical area. These include the Metro Wastewater Treatment Plant Expansion, the Rabanco Recycling Facility, and Phase VI of the Black River Corporate Park. The cumulative impacts of these other projects have been considered in the formulation of this mitigation document, and will . be or have been considered in the mitigation documents of these other projects during their environmental review. SEPA states that: "After its decision each agency shall make available to the public a document that states the decisions. The document shall state the mitigation measures, if any, that will be implemented as part of the decisions, including any monitoring of environmental impacts." (WAC 197- 11- 660(1)(b)). This document is intended to meet this requirement. As well as analyzing the environmental impacts, the City of Renton, under its land use provisions, must assess its many objectives and goals and decide how this project furthers or conflicts with them. Some City goals may be internally conflicting. When this occurs, the City believes that the SEPA process mandates a close environmental analysis to determine priorities. If the priorities are established and the project is able to mitigate its impacts sufficiently, then the City believes it should proceed. This document presents mitigation measures necessary for the ultimate construction of the Black River CDL Recycling and Transfer Station. THE PROPOSAL The Rabanco Regional Landfill Company (RRLC) proposes constructing and operating a recycling and transfer station for construction and demolition debris, and incidental, mixed Toads of landclearing debris. Discrete loads of landclearing debris (including mud and dirt) and yard waste will be hauled to other specialized facilities, such as Cedar Hills composting facility. The proposed recycling and transfer facility would be constructed on a 13.5 acre site in the City of Renton. At full operation, up to approximately 90,000 cubic yards per month of construction, demolition, and landclearing (CDL) waste would be processed. After recyclables are extracted, the remaining waste would be transferred to the Roosevelt Regional Landfill in Klickitat County, Washington. The proposed facility could be initially scaled down for processing smaller volumes (approximately 40,000 cubic yards per month) of CDL debris. Gradually, the facility could be expanded to process the larger volumes of waste. Analysis in the EIS is based on handling the larger waste volume. Reducing the amount of CDL debris processed at the proposed facility would not reduce the size of any of the proposed structures. One of the primary objectives of the proposal is to provide a specialized recycling facility for CDL waste. The proposed facility would provide the means for processing CDL waste in an economically sound manner. In processing CDL waste, the Rabanco Regional Landfill Company would be allowed to recapture concrete, wood, metal, and other materials currently valuable on the recycling market. The material to be recycled will be shipped to the recycling market in trucks. These truck trips have been included in the 808 truck trips per day that the project is anticipated to generate. PURPOSE AND NEED In 1990, King County's solid waste system handled approximately 148,000 tons of CDL waste. The closure of the Newcastle Landfill in January 1990 and the Mt. Olivet Landfill in August 1990 were followed by an emergency public rule (Put -7 -1), issued by the King County Board of Supervisors, 2 revising the waste acceptance policy for CDL waste at County solid waste facilities. With this new policy, there are three disposal options for non - recycled CDL waste generated in King County: (1) the Hidden Valley Landfill in Pierce County, (2) the Morrison Sand and Gravel disposal facility in Kitsap County, (3) and the King County Transfer Station (from where waste is transferred to a permanent disposal site). The Hidden Valley Landfill is scheduled to close by November 31, 1991, and the Morrison Sand and Gravel facility has little remaining capacity. One of the objectives in the King County Comprehensive Solid Waste Management Plan (CSWMP) is to reduce to the maximum extent possible the amount of solid waste requiring disposal: The CSWMP recommends that the County select and contract with a vendor to plan and permit one or more new facilities for disposal and potential recycling of landclearing and demolition waste. More recently, this waste stream has been termed construction, demolition, and landclearing debris (CDL). On December 10, 1990, the Environmental Review Committee issued a Determination of Significance for the Black River CDL Recycling and Transfer Station project. A Draft EIS (issued June 17, 1991) and Final EIS (issued August 21, 1991) were prepared for this project. The content of the EIS was determined by the Lead Agency (in this case, the City of Renton) based, in part, on key sections of the SEPA rules (197 -11 -402, 408, 430, and 440) together with results of the EIS scoping process. The Draft Black River CDL Recycling and Transfer Station EIS included an analysis of the proposed action and a no action alternative. The Final EIS responded to the comments received by the City of Renton on the Draft EIS. This document has been prepared as a summary of the mitigation measures contained in the Draft and Final EIS and also provides the time periods in which the mitigation measures must be completed. ELEMENTS OF THE ENVIRONMENT A. EARTH SOILS In general the upper soil horizon (from 0 to 10 feet) consists of medium -dense fill composed of sandy gravel. This overlays a 20 to 30 -foot layer of fill consisting of a soft medium -stiff, sandy, clayey silt. The soft clayey silt appears to be a result of deposits from former settling ponds. In the northern part of the site, below the sandy, clayey silt, is a native material consisting mostly of hard silty sandstone. In the southern part of the site, the sandy clayey silt is generally underlain by a medium -dense silty sand. Upper soil layers would be affected as excavation and paving occur. Most of the proposed structures would be located atop soft clay and silt. These soils have a high moisture content and would tend to settle over time as water slowly drains from them. The rate of soil settlement would increase as pressure is exerted from the structure's concrete floor slabs and foundations, container storage slabs, driveways, and paved working areas. Estimates of settlements are about 1 to 2 feet. Impacts to soils caused by erosion should be insignificant because the site slopes are relatively mild. Along steeper slopes, erosion impacts could be minimized by following standard mitigation practices. TOPOGRAPHY The majority of the site is flat to gently sloping. On the eastern and southeastern edge of the site, the slope drops quickly from a flat -lying area (adjacent to 68th Avenue South) to an area of lower elevation. This drop forms an approximately 22.5 degree bank along much of the eastern boundary. The highest elevation is approximately 75 feet (at the top of bank) while the lowest elevation of the site is approximately 26 feet. The site is currently undeveloped. Most development of the proposed Transfer Station would occur on relatively level surface and would not significantly affect topography. Most grading and excavation would occur on the low -lying elevations of the site during preparation of the construction of the main building and container storage area. 3 • • • RECOMMENDATION: 1) The applicant shall, in order to minimize erosion, have a certified geotech engineer prepare an erosion control plan, prior to the issuance of any site preparation /building permits; such a plan should include, but not be limited to, the installation of such items as: a) water - diversion berms, b) swales, c) permanent benches, d) a sturdy vegetative cover, e) the use of erosion control matting on slopes until a vegetation cover is established; and f) the installation of temporary . plastic covering along all exposed slopes. This plan shall be prepared to the satisfaction of the Department of Planning /Building /Public Works. The temporary erosion control measures shall be maintained throughout the construction phase of the project and until the permanent erosion control measures are fully established and landscaped to the satisfaction of the Department of Building /Planning /Public Works. The permanent erosion control measures shall be maintained for the life of this project. 2) The applicant shall, in order to ensure that the soils are drained properly and that the drainage meets City of Renton water quality standards, develop plans for a drainage system to consolidate underlying soft soils in advance of construction. These plans shall be developed to the satisfaction of the Storm Water Utility Section and implemented prior to the construction of the permanent buildings on the project site. POLICY NEXUS King County Surface Water Design Manual; City of Renton Comprehensive Plan I.G., I.M.2., VI.A., VIII.C.; Mining, Excavation, & Grading Ordinance (4 -10); Environmental Review Ordinance (4-6); WAC 197 -11 -768. SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS Based on the soils analysis prepared by Rittenhouse -Zeman and Associates it appears that soil settlement would be the primary impact associated with the proposal. Recommended mitigation measures would allow the proposal to avoid significant adverse impacts. B. AIR Air quality impacts can result from traffic and from on -site emissions both during the construction phase and the operation of the proposed development. The Puget Sound Air Pollution Control Agency is responsible for controlling stationary sources of air pollution in the central Puget Sound region, while WSDOE is responsible for monitoring carbon monoxide (CO) levels. None of the monitoring sites for either of these agencies are close enough to the study area to be considered representative of the CO concentrations in the project area. Given the current density of land use development and the existing roadway network, existing violations of the CO standards are considered unlikely in the immediate vicinity of the project area. The applicant will be asked, to ensure that the proposed project does not have a significant impact on the_air quality, to provide a dust control system within the building and to use electric - powered vehicles whenever feasible. 4 • RECOMMENDATIONS: 3) The applicant shall, in order to limit impacts to air quality from operations occurring within the building, install a dust control system that meets current State and Federal standards for recycling centers. Design plans for this system shall be; a) submitted to the satisfaction of the Development Services Division, b) prepared with the building permit application, and c) installed prior to the issuance of occupancy permits. The dust control system shall be maintained for the life of the project. - 4) The applicant shall, in order to limit impacts to air quality and to reduce potential noise impacts from operations outside of the building, use electric - powered yard equipment (e.g. yard goat) where feasible. Prior to the issuance of building permits, the applicant shall present to the City of Renton a list of the yard equipment indicating which ones shall be battery powered and the means of propulsion for the remainder. The applicant shall, in order to limit impacts to air quality from the operation of the wood chipper, limit the wood to be processed through the wood chipper to non - painted and untreated woods. 6) The applicant shall, in order to limit the potential adverse impacts to air quality, water quality, and soil, provide a material handling plan for materials that may be hazardous (e.g. asbestos, pesticides, oils) to the satisfaction of the Development Services Division prior to the issuance of occupancy permits. POLICY NEXUS Environmental Review Ordinance (4 -6); City of Renton, Comprehensive Plan I.B., VI.A.1.; WAC 197 -11 -768. SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS No significant unavoidable adverse impacts would be expected. C. WATER SURFACE WATER AND RUNOFF /ABSORPTION The EIS stated that expected pollutants from the site under existing conditions are sediment and some urban pollutants. The concentrations of sediment in runoff from the site are probably quite high, because most of the site is gravel or exposed, unstable soil. Only a small portion of the site is vegetated. The EIS reports that the proposed site layout would increase the impervious area from 0.6 to 10.6 acres. Because the existing fill areas, sedimentation ponds, and railroad grade are not highly permeable, the difference in absorption rates between pre- and post - development surfaces and the corresponding increases in runoff rates are not large. The pre - development 2- and 10 -year runoff rates of 4.4 and 8.4 cfs, respectively, would increase to 6.6 and 10.5 cfs, respectively, after development of the proposed project. SURFACE WATER QUALITY The EIS notes that the overall existing drainage pattern toward the 30 -inch pipe on the north end of the site would remain the same. Most of the site would be covered by impervious surfaces, which would stabilize disturbed soils and gravel and reduce the concentration of sediment in runoff from the site. The applicant will need to develop a storm water system that is in compliance with the King County Surface Water Design Manual, as adopted by the City of Renton. 5 0 • III • FLOODING Although no surface waters occur on the project site, there is a wetlands area located at the discharge pipe under the railroad. This wetland is hydrologically connected to the Green River during high flows in the river. Panel numbers 326D and 328D of the Flood Insurance Rate Map (FEMA 1989) for the site indicate that the portion of the site on which construction will occur lies in Zone "C ". Zone C is an area of minimal flooding and is not considered to be in the 100 -year floodplain. However, the wetland area does lie below the 100 -year flood elevation of the river and would be subject to flooding during the occurrence of the 100 -year flood on the Green River. No activity is proposed on the site at elevations presently below the 100 -year flood elevation. Construction plans must indicate the delineation of the 100 -year flood elevation. GROUNDWATER A major portion of the site would be covered by impervious surface (pavement or buildings). The EIS states that any precipitation that would contact wastes would be collected and treated as runoff instead of being recharged directly into the groundwater. A stormwater management facility would be designed to include multi - celled ponds and other in -line treatment structures to retard discharge runoff and reduce pollutants. Because the CDL materials would be processed within an enclosed building and stored in closed containers, precipitation is not expected, under normal circumstances, to directly contact wastes. Some contact by rainfall is unavoidable. However, the EIS states that leachates generated by the types of demolition debris waste to be handled in this facility are generally not as toxic as those generated by municipal and hazardous waste streams. The storm water from the site will also be treated in a biofiltration system prior to its release. off -site. RECOMMENDATIONS: 7) The applicant shall mail a notice to all CDL debris trucking firms that discrete loads of hazardous materials (e.g. hazardous waste, pesticides, asbestos) will not be accepted at the Black River facility. Appropriate signage shall also be located at the entrance to the project site. The notice to be mailed shall also contain a list of acceptable materials. A copy of this notice shall be submitted to the Development Services Division prior to the issuance of occupancy permits. 8) The applicant shall, in order to protect the water quality at the project site, refuse entry to any trucks carrying discrete loads of hazardous materials or discrete loads of asbestos. Trucks that are refused entry shall be directed to other appropriate transfer sites. The applicant shall have a minimum of one employee specially trained to identify hazardous materials and asbestos debris on -duty at all times that the facility is in operation. The applicant shall, as a portion of the project site (where the wetland is located) is located within the 100 -year flood plain, as identified on the FEMA maps, provide an agreement to the satisfaction of the City Attorney, and submitted prior to the issuance of occupancy permits, to hold the City harmless from any claims which may result due to damage occurring to the subject property as the result of flooding of the subject property. POLICY NEXUS Renton Storm and Surface Water Drainage Ordinance (4 -22); King County Surface Water Design Manual; Environmental Review Ordinance (4-6); Comprehensive Plan I.A., I.C., I.G., I.H., I.I.; Green River Valley Plan I.C.4. 6 • • • SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS - NONE If the draft stormwater management system plan is incorporated into the design of the proposed facility, no unavoidable adverse impacts to surface water resources would occur. The configuration of the stormwater management system may be modified during the development of the project's final design and construction plan. A revised stormwater management system that meets the standards of the King County Surface Water Design Manual would mitigate anticipated adverse impacts. No significant unavoidable adverse impacts to groundwater resources beneath the site would be expected. D. PLANTS AND ANIMALS WETLANDS AND VEGETATION Site plans, aerial photos, soil survey maps and reports were reviewed in the preparation of the EIS to identify potential wetlands on the property. King County soil maps (Snyder et al. 1973), Hydric Soils of the United States (U.S.D.A. 1987; SCS 1987), and a Soil Conservation Service report (1989) provided information on wetland soils. The property was visited and vegetation, soil, and hydrology were examined for wetland characteristics using the Federal Manual for Identifying and Delineating Jurisdictional Wetlands. The EIS identified a small, natural wetland along the northern edge of the property. Separated from the wetlands by a dike is an old sedimentation basin once used in connection with the gravel pit operation located across the road (68th Ave. S /Monster Road). The wetland and the old sedimentation basin are connected by a culvert. Another culvert beneath the railroad tracks connects the wetlands to the Duwamish River. Both the existing sedimentation basin and the wetlands are characterized by a willow- dominated shrub community with a reed canarygrass and cattail - dominated emergent community. WILDLIFE AND HABITAT The EIS notes that the project site is highly disturbed and is surrounded by a mix of industrial and residential uses. The site has a history of being used for top soil and gravel mining, multiple sedimentation ponds for gravel washing and stormwater control, and storage of fill material and heavy equipment. Although the EIS did not discover the presence of soil contamination, the use of this site for the storage of heavy equipment in the past does indicate that the potential for soil contamination does exist. Should contaminated soils be discovered during the construction phase of the project the applicant will need to provide a remediation plan. The contamination shall be mitigated prior to continuing the construction of the project. Habitat quality ranges from nonexistent on the compacted fill area to moderate on the adjacent forested hillside. Wildlife using the site can be expected to include a high proportion of urban - adapted native and non - native species such as American Crow, house sparrow, rock dove, house mouse, raccoon, and opossum. There are no known threatened, endangered, or sensitive animals on the site, and the EIS indicates that none are likely to occur because the site is highly disturbed and has poor habitat quality. A nesting colony of great blue herons is located approximately 0.6 miles east of the project site and about 300 meters north of Oakesdale Avenue. This site is protected from noise generated at the project site by the intervening hillside. FISHERIES The EIS identified the Duwamish River as the only watercourse that could be affected by the proposed development. The river flows north to Elliot Bay through a highly urbanized basin, flanked by high density residential and industrial development. The King County 7 41P II • Reconnaissance Report #26, June 1987, noted that "the discharge of oils and other toxicants from thousands of acres of industrial land and the dumping of domestic garbage (common though illegal) have produced serious water quality problems ". The Duwamish River provides passage to upstream spawning areas for returning coho, Chinook, and chum salmon. The location of the proposed recycling facility is upland, more than 400 feet east of the Duwamish River, and is separated by a raised railroad bed. , The applicant will 'be required to provide a water quality management system to ensure that this facility does not negatively impact the Duwamish River. RECOMMENDATIONS: 10) The applicant shall, in order to ensure that the surface.. water quality is not negatively impacted by this project, install a stormwater water management system (retention /detention system), prior to initiating any grading, filling, or construction, so that runoff from the impermeable surface would flow into the wetland area at the north end of the site at approximately the same rate as before the installation of the transfer station. This system shall be installed prior to the issuance of any occupancy permits and maintained for the life of the project. 11) The applicant shall, in order to ensure that future operations do not negatively impact the existing wetland, provide a twenty -five foot (25') landscaped buffer around the existing wetland. Landscaping plans for this buffer shall be submitted to the satisfaction of the Development Services Division prior to the issuance of Building Permit applications and be fully installed prior to the issuance of any occupancy permits. 12) The applicant shall, in order to mitigate the loss of vegetation and wildlife habitat that has occurred on this site, establish a wildlife habitat area on the project site equal to two percent (2 %) of the project site. Plans for the wildlife habitat area shall be submitted to the satisfaction of the Development Services Division with the Building Permit application and fully planted prior to the issuance of occupancy permits. 13) The applicant shall, in order to improve the quality of the existing wetland and to minimize the potential adverse impacts to water quality, provide vegetation enhancement within the existing wetland to the satisfaction of the Development Services Division. Plans for the wetlands enhancement shall be submitted prior to the issuance of Building Permits and all work shall be completed prior to the issuance of occupancy permits. 14) The applicant shall, in order to ensure the survival of the wetland enhancement vegetation, buffer zone plantings and wildlife habitat area, develop a comprehensive plan for monitoring and assuring successful preservation of the wetland, protection of water quality, and restoration of wildlife habitat to the satisfaction of the Development Services Division. This plan shall include visits by a qualified wetlands ecologist, hired by the applicant and approved by the City, at 6 months, 1 year, 2 years and 3 years following project installation to verify success of preservation and revegatation efforts. Copies of the reports from the wetlands ecologist shall be submitted to the Development Planning Section and the owner of this facility. If any of the plantings within the buffer area or wetlands are found to be in need of replacement during these inspections, the report shall include the modifications of designs and /or re- planting of the dead or dying plant materials and the time period in which these efforts will occur. This report shall be submitted to the satisfaction of the Development Services Division. The comprehensive monitoring plan shall be submitted to the satisfaction of the Development Services Division prior to the issuance of building permits. All cost associated with the monitoring program and any re- planting of the wetlands and buffer areas shall be borne by the facility owner, lessees, assignees or successors in interest. 8 • • POLICY NEXUS Environmental Review Ordinance (4-6); Comprehensive Plan I.A., I.C.,.I.D., I.E.., I.J.; Green River Valley Plan I.C.B. SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS - NONE The proposal would avoid significant adverse impacts to . wetlands, vegetation and .., fisheries with the provision of the mitigation measures identified above. The loss of the existing low quality wildlife habitat on site will be off -set by the provision of a high quality wildlife habitat equal to 2% of the project site area. E. NOISE IMPACTS OF OPERATIONS ACTIVITIES The noise generated at the proposed Black River facilities can be expected to be similar to the types of noise generated at the existing facility at Third and Lander Streets in Seattle. Sound level measurements, by TRC Environmental Consultants, found the dozer, front -end loader, and trucks to be the primary noise sources at the site. Trucks generated noise when backing up the ramp and when rewing their engines while dumping at the existing facility. The clanging of doors occasionally also generated an impulsive noise from the trucks. At the proposed Black River facility these activities would occur within an enclosed building. The noise generated by the front -end loader and the dozer would occur when they were sorting and compacting the CDL debris. This activity would occur within the enclosed building. The applicant has also proposed to install a wood grinder in this facility. Similar grinders at other facilities were found by TRC to generate a noise level of 74 dBA at 100 feet. The grinder would be installed in the building and enclosed on three sides by an acoustical block wall which should reduce the noise levels outside of the building to the Code - required standards (65 dBA at the property line). A final source of noise generated at this site would be the arrival of and departure of trains three times per week. The peak noise level of the train is predicted by TRC to be 84 dBA when measured at 100 feet from the source. The train would only add 0.1 dBA to the daily average equivalent sound level. This increase in ambient sound levels would be negligible. NOISE IMPACTS ON SURROUNDING AREAS Noise impacts associated with the proposed facility would be reduced by several factors: distance, atmospheric attenuation, and intervening terrain. The EIS found that noise levels at the sensitive receptors (e.g. heron rockery, apartments, single - family residential areas, recreation areas) would fall within acceptable ranges. TRUCK NOISE IMPACTS The EIS used the existing CDL debris facility at Third and Lander to determine the potential noise impacts of trucks at the proposed Black River facility. To evaluate potential changes in traffic noise due to trucks serving the waste recycling facility, an FHWA (U.S. Federal Highway Administration) traffic noise model was employed within the EIS. As noted above the model found that noise generated by the trucks would fall within acceptable ranges at the sensitive receptors. However, the EIS stated that the noise increase along Oakesdale Ave. would be significant but that the noise level at the heron rockery would not be adversely impacted due to the distance from the roadway to the heron rockery. 9 • RECOMMENDATIONS: 15) The applicant shall, in order to reduce the noise impacts on surrounding areas, limit operations to between 7 am and 8 pm Monday through Friday and 8 am to 6 pm on Saturday. The facilities shall be closed on Sunday and National Holidays. The applicant shall discourage truckers from letting their truck engines idle outside of the project site before the gates are opened. The applicant shall locate a sign at the entrance gate with the hours of operation and requiring all trucks arriving early to shut off their engines. The applicant than provide an agreement, acceptable in form to the City Attorney, limiting the hours of operation to the satisfaction of the Development Services Division prior to the issuance of occupancy permits. 16) The applicant shall, in order to reduce noise levels at the project boundaries, incorporate the following design features into the proposed facility: a) limitation of most transfer operations (e.g. dumping and sorting of debris, filling of containers) to inside of the processing building, Only the necessary movement of containers shall occur outside of the building, b) enclosure of the tipping floor, sorting area, and all material container loading areas within the building, and c) location of the wood chipper within the main building in an area enclosed on three sides by an acoustical block wall that extends up to a minimum of two feet over the height of any motor or a minimum of six feet, the open side of this area shall be oriented away from the residential area to the north and west. The opening of the enclosure around the wood chipper shall be directed away from all doors or openings leading to the exterior of the building. 17) The applicant shall, in order to reduce noise impacts from vehicles, provide an agreement to minimize noise from back -up beepers in a manner that complies with state and federal regulations. The applicant shall provide this agreement to the satisfaction of the Development Services Division and in a form acceptable to the City Attorney prior to the issuance of occupancy permits. 18) The applicant shall, in order to educate their staff and users of the facility on the potential noise impacts and the affects on surrounding properties, develop an annual training program (e.g. shutting equipment down instead of letting it idle for long periods of time, on -site noise sources) for their own on -site personnel and hand outs for truck drivers. This training program must be approved by the Development Services Division prior to the issuance of occupancy permits. 19) The applicant shall, in order to ensure that the noise reduction techniques applied to the project are effective, deposit $25,000.00 in an escrow account to cover the cost of noise monitoring to be conducted within six months of the start of the operation of the facility. This account will only be used by the City of Renton to complete the noise monitoring study. Any unused funds will be returned to the applicant within one year of the issuance of occupancy permits. The applicant shall also provide the City with a surety device for $75,000.00 which the City of Renton may use to provide additional noise attenuation methods off -site identified by the required noise study. The applicant shall install additional noise attenuation within six months of the completion of the noise monitoring study. If the surety device is not used by the City of Renton it shall be released by the City within 2 years from the date of the completion of the noise study. 20) The applicant shall, in order to reduce noise impacts to nearby residential areas, restrict outdoor construction activities to weekdays between the hours of 7 a.m. and 8 p.m. and 8 a.m. to 6 p.m. on Saturdays with no construction to occur on Sundays or holidays. 10 • • * 21) The applicant shall, in order to reduce noise impacts, ensure that all construction equipment has sound control devices no less effective than those provided on original equipment (e.g. equipment mufflers and noise shrouds are intact and operational). 22) The applicant shall, in order to control noise, provide a noise education program for operators of construction equipment and haul trucks. The program shall discourage wide open throttles, compression release brakes, and provide incentives for operators using noise suppression methods (i.e. shutting off equipment when not in use). 23) The applicant shall, in order to reduce noise and vibration impacts on nearby wildlife habitat (e.g. wetland area at north end of project site, Green and Duwamish Rivers) and on area residents, ensure that auger cast -in -place piling construction is used in lieu of conventional pile driving where soil conditions allow for cast -in -place pilings. In areas where the applicant can demonstrate to the City's satisfaction that cast -in -place pilings are not feasible, the applicant shall use the construction method which will produce the least amount of noise and vibration. POLICY NEXUS Comprehensive Plan I.B., VI.A.; Green River Valley Plan I.B., I.C.3; Environmental Review Ordinance (4-6). SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS There will be a significant increase in traffic noise on Oakesdale Parkway between the recycling facilities and South Grady Way. The EIS notes that due to the distance between the roadway and the heron rookery the noise generated by the truck traffic will be lower than the existing background noise level within the rookery. F. LAND AND SHORELINES ZONING The proposal is an allowed use in the L -1 zoning district (Light Industrial), and the site design complies with the L -1 district's relevant development standards. The L -1 District allows for the manufacturing, processing, assembling of articles, products or merchandise. The City of Renton has determined that the correct terminology for the recycling and transfer station product servicing since it is not a manufacturing use. The proposed use primarily processes products or merchandise from previously prepared natural or synthetic materials. The zoning on the land surrounding the project site is for light and /or heavy industry, allowing uses similar to and compatible with the proposal. Fort Dent Park and the Foster Golf Links are located across the river from the subject property. The proposed recycling and transfer facility includes a variety of design features (e.g. landscaping, color scheme, building design) intended to ensure that the proposed facility is compatible with these recreational land uses. LAND -USE PLANS AND POLICIES The applicant will need to improve water and sewer service to the project site. In order to accomplish this task the applicant has proposed to attach a water and a sewer line to the Monster Road Bridge. Any constructions that occurs within 200 feet of a shore line is regulated by the Shoreline Master Program. 11 • • • RECOMMENDATION: No special mitigation measures required beyond the Code- required standards. SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS - NONE Significant adverse impacts can be avoided with the mitigation discussed above. G. 'AESTHETICS The proposed facility lies on the northeast edge of the Duwamish River valley floor. Immediately northeast the valley wall rises to a height of several hundred feet above the valley floor. The opposite valley wall also rises several hundred feet above the valley floor, and lies about 0.33 miles southwest of the site. On the southwest side, the site is bordered by the Burlington Northern and Union Pacific tracks. These tracks run the length of the valley on a 5- to 20- foot -high berm. As shown on the photos included in the EIS, the project would be at least partially visible from Fort Dent Park, Foster Golf Links, the residential areas on the hillsides and the adjacent roadway. There is also the concern that dirt, dust, and debris could blow out of the uncovered trucks on the way to or leaving this development. Requiring the trucks to cover their loads will reduce the potential for this impact to occur. The applicant will also need to develop agreements with the local governments in the area to provide funding for the additional cleaning of the streets used to access the proposed facility. RECOMMENDATIONS: 24) The applicant shall, in order to reduce the apparent visual mass of the building, paint the facility shades of earthen tones (e.g. green and /or brown as identified in the EIS) including both its walls and roof. Building color shall be varied in color and tone to reduce its apparent mass. Medium, low- reflective tone values should be used. The applicant shall submit color samples and a color scheme to the satisfaction of the Development Planning Section prior to the issuance of building permits. 25) The applicant shall, in order to improve the aesthetic appearance of the project site, submit a detailed landscape plan to the Development Planning Section prior to the issuance of building permits and be approved prior to the issuance of occupancy permits. This plan shall include but not be limited to the following: a) An irrigated landscape strip along 68th Street South (Monster Road) a minimum of fifteen (15) feet in width. A combination of deciduous and evergreen trees and shrubs shall be used within this area. b) Landscaping along the westerly border of the project site and in islands adjacent to the southern, western, and northern face of the building, except where it would interfere with the safe loading and movement of the railroad cars or the movement of equipment on site. Planting areas shall be a minimum of ten (10) feet in width and contain a mix of evergreen trees (minimum of 8 feet in height) and shrubs (minimum of five gallons in size). c) All garbage and /or refuse dumpster areas shall be visually screened by an opaque fence, landscaping or some combination thereof. 12 d) Landscaping shall include a mix of deciduous and evergreen trees and shrubs in order to provide screening of the site all year. Deciduous trees shall be a minimum of 2" in diameter, evergreen trees shall be a minimum of eight feet in height, and shrubs shall be a minimum of five gallons in size. e) To ensure maintenance of the proposed landscaping a surety device equal to ten percent (10 %) of the value of the landscaping and valid for three years from the date the landscaping is installed shall be provided to the City of Renton prior to the issuance of occupancy permits. If the applicant receives written permission from the City of Renton to delay the installation of the landscape materials, the surety device may also be delayed until the landscape has been completed. 26) The applicant shall, in order to reduce the potential for litter or dust blowing from the site, ensure that all paved surfaces are washed down or cleaned at least daily, up to four times daily if conditions warrant it, that all landscaped areas are cleaned daily to remove litter /debris, and that all storage containers are properly covered by a tarp or other suitable secure device. The applicant shall deposit $50,000 into an escrow account that the City of Renton may draw against for on -site trash removal. The applicant shall prepare an agreement to the satisfaction of the City Attorney allowing the City of Renton to inspect the facility and if the applicant does not provide the remedial action recommended by the City within 30 days to reimburse the City for all expenses incurred for the required clean -up. The escrow account and the agreement shall be provided to the City of Renton prior to the issuance of occupancy permits. 27) The applicant shall, in order to reduce the amount of litter or other light CDL debris that may blow out of trucks, require that all trucks hauling any CDL debris onto, or off of the project site are properly covered. Trucks that do not have covers would be refused access to the facilities. 28) The applicant shall, in order to reduce the potential for debris blowing out of trucks, develop a program that includes but is not necessarily limited to training programs for haulers to convince haulers to properly cover their Toads with tarps, fines for trucks with improperly covered loads or other methods that prevent litter blow -out. The applicant will also keep a list of the flagrant abusers and if the fines prove ineffective (over 12 violations in a 12 month period), ban the hauler from use of the Black River facility for 12 months. The fines collected shall be used to reimburse the City of Renton for clean up required along City roads. 29) The applicant shall, prior to the issuance of building permits, develop agreements with the City of Renton, City of Tukwila and King County to cover the cost of extraordinary services required to remove litter, CDL debris and dirt from roadsides due to this project. The cost of these agreements will be passed on to the individual truck drivers arriving with uncovered or improperly covered loads in the way of an extra fee or fine. Note: In the case of a dispute between the applicant and another jurisdiction on the wording or dollar value of this agreement, the City of Renton as lead agency would be the final arbitrator. 30) The applicant shall, in order to reduce the visual aspect of the project as seen from the west, develop measures to reduce the amount of activity on the western border of the site, nearest Foster Golf Links. Prior to the issuance of building permits the applicant shall redesign the building to orient the loading bays so that they open to the south. The applicant may orient a maximum of one loading bay towards the west if the applicant can demonstrate to the satisfaction of the Development Services Division that it would be infeasible to orient the bay in any other direction. 13 • • • 31) The applicant shall, in order to reduce the potential impacts from light and glare to surrounding land uses, ensure that all on -site lighting is located and shielded to contain all visible glare on -site. The type, intensity, height, and location of lighting standards to be installed on the project site shall be indicated on the landscape plans. These plans shall be submitted to the satisfaction of the Development Services Division prior to the issuance of site preparation /building permits. NOTE TO APPLICANT The applicant must, prior to the erection of any signs on the project site, submit sign permit applications for all proposed signs under the City's Sign Ordinance. POLICY NEXUS Landscaping Ordinance (4- 31 -34); Environmental Review Ordinance (4-6); Comprehensive Plan I.A., I.E., III.C., III.D., VI.A, VI.B.; Green River Valley Plan I.B., I.C.3. SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS - NONE Significant adverse impacts can be avoided with the mitigations measures discussed above. However, until the vegetative screen, recommended above, has developed, views from the golf course will be impacted by the proposed structure. Significant adverse visual impacts could develop if CDL debris were allowed to build -up along the roads leading to the facility or on the subject property. Compliance with the mitigation measures listed above should limit the potential adverse visual impacts. H. TRANSPORTATION STREET NETWORK The EIS states that the majority of truck trips generated by the facility would originate from south and east King County because of an existing recycling facility that serves the demands generated in Seattle to the north. However, there appears to be no guarantee that over the life of the proposed facility that routes might not change, that the possible closure of existing facilities or shifts in the anticipated markets would not alter the proposed routes. Most trucks will exit Interstate 405, Interstate 5, and Highway 167, and follow the existing street network to the site. TRAFFIC VOLUMES AND OPERATION The EIS indicates that based upon the forecasted maximum volumes of waste and the most likely average Toad size, this facility is expected to accommodate up to 808 trips per day involving a full range of container -type trucks. This translates into approximately 404 trips in and 404 trips out. The 10 to 20 employees on -site are expected to generate an average of up to 60 vehicle trips per day. HEAVY TRUCK TRAFFIC /ROAD SURFACES As the majority of trips generated by the proposed project will be trucks, the City is concerned with the potential cumulative impacts to road surfaces and bridges that this and nearby projects could generate. Some of the routes that could potentially be used by trucks accessing the project site are located outside of the City of Renton in the City of Tukwila and the King County area. The applicant will need to enter into agreements with the adjacent jurisdictions as well as the City of Renton to mitigate potential adverse impact to existing and new roadways used as routes to and from the proposed facility. The EIS also noted that the line of sight distance at the entrance /exit of the project site could be a potential problem. Signalization of this intersection would reduce the potential for accidents occurring in this area. 14 RECOMMENDATIONS: 32) The applicant shall, in order to ensure that the routes used by the trucks accessing the project site are not adversely impacted, provide a proposed truck routes map to the satisfaction of the Development Services Division and the Transportation Systems Division prior to the issuance of building permits. This map shall indicate the routes trucks will use from the roads included in the proposed Truck Routes Ordinance to the project site. The applicant shall encourage all truck drivers to adhere to the prescribed routes which have been designed and constructed to handle trucks. Copies of this map shall be mailed, on a semi - annual schedule, to the hauling firms and handed to the truck drivers to reinforce the use of designated truck routes. 33) The applicant shall, in order to mitigate potential adverse impacts to the road surface and bridges, sign an agreement with the City of Renton, prior to the issuance of building permits, which allows the City to recover costs associated with unusual wear and tear to road surfaces including bridge deck surfaces. The methodology of the agreement shall be as follows: S = (A) X (0.2) [(C' - C) / D] X (Truck Ratio) Where: S = The proportion of the total cost attributable to a given project or development (i.e. The Black River Recycle and Transfer Center). A = Cost of the overlay (One inch of overlay plus prelevel and preparation work). C' = Measured change in pavement condition rating (PCR) during the survey period. PCR at beginning of monitoring period - PCR at the end of the monitoring period. C = Normal change in PCR for the same time period. Determined by monitoring PCR conditions one year prior to opening (Would likely range between 5 and 15 points per year). D = Typical overlay life in years. Truck Ratio = Projected Generated Traffic (PGT) divided by Average Daily Truck Traffic (ADT) times the number of days the project is operational, plus Project Generated Traffic. The cost of the analysis described above shall be borne by the applicant. 34) The applicant shall, in order to mitigate impacts to the streets within the City of Tukwila, sign an agreement with the City of Tukwila, prior to the issuance of occupancy permits by the City of Renton, to provide a one -time fee of $1,000.00 per peak -hour trip expected to be generated by the project through the intersection of Interurban Avenue /Grady Way and West Valley Highway /South 156th Street provided that the applicant has reviewed and verified the basis for the fair share calculations. 35) The applicant shall, in order to reduce the potential for accidents occurring at the entrance to the project site, install a signal device or other traffic control devices deemed appropriate by the Transportation Systems Division. Any required traffic safety device or signal shall be installed prior to the issuance of occupancy permits unless a deferral is obtained from the City of Renton Board of Public Works. 15 36) The applicant shall, in order to reduce the number of potential vehicle trips generated by this facility, utilize a program, approved by the Development Services Division, to ensure that loads of recyclable concrete, asphalt, and compostable land clearing waste are diverted to facilities designed to handle these materials. The applicant, shall provide an easement to allow access to the site to allow periodic monitoring of the recycling and transfer activities by City staff. This document is to be submitted in a form acceptable to the City Attorney and shall be duly recorded with King County prior to the issuance of building permits. Trucks carrying discrete loads of these materials shall be denied entrance into the recycling building. Acceptance of discrete loads of these materials at the Black River facilities shall constitute grounds for closure of the facility until further environmental review of the expanded operation. 37) The applicant shall, in order to reduce the adverse impact potential of additional truck trips generated by the removal of CDL waste from the project site by trucks in the event that rail service is temporarily suspended (30 days or less), provide a Backup Transfer Option Plan to the satisfaction of the Transportation Systems Division prior to the issuance of occupancy permits. This plan shall discuss the backup system of transferring waste materials from the project site to the landfill in the advent that rail service is temporarily discontinued. The plan also needs to discuss methods to ensure that the number of vehicle trips per day do not exceed the levels reviewed in the EIS. 38) The applicant shall, in order to mitigate the impacts to the Monster Road Bridge, the existing structure south of the development, sign an agreement to pay a proportional share of the cost of replacing a three lane bridge. The proportional share shall be determined by dividing the equivalent axle loads generated by Rabanco by the equivalent axle Toads generated by all trucks and heavy vehicles crossing the bridge. The agreement shall be submitted to the satisfaction of the Transportation Systems Division and in a form acceptable to the City Attorney. The signed agreement shall be submitted to the City prior to the issuance of building permits. Payment of the proportional share shall be made by January 1, 1993 or within one year after granting of an occupancy permit, whichever occurs first. The equivalent axle loads shall be determined by a combination of actual weight, where available, and by classification counts. The cost of the bridge replacement shall be as estimated by the Transportation System Division. Notes to Applicant The project is limited to a maximum of 808 truck trips per day and 90,000 cubic yards of CDL debris per month as identified in the EIS. If, at any future time, the applicant or future owners /lessees desire to expand beyond this level of development, the additional information would be included in an addendum to the EIS, or in other separate environmental documentation depending on the significance of environmental issues raised by the new information and the extent to which the range of possible impacts is addressed in this EIS. The applicant is encouraged to enter into agreements for the maintenance and repair of roads used by haulers to access the proposed recycling and transfer station with the City of Tukwila and King County prior to the issuance of occupancy permits.

The increase of noise along Oakesdale Ave. by approximately 7 dBA is a significant adverse impact. This increase in noise is not expected to have an adverse impact on adjacent commercial buildings, area residents, or the heron rookery due to the distance between the road and the rockery and existing ambient background noise levels in the area. I. PUBLIC SERVICES AND UTILITIES PARKS AND RECREATION Two heavily -used recreational facilities, the Foster Golf Links and Fort Dent Park, are located west and south of the project site, respectively. The City of Renton proposed Master Trails Plan and proposed Comprehensive Park and Recreation Master Plan indicate that bicycling and pedestrian hiking trails shall be constructed in this area. The applicant will also need to provide on -site recreation opportunities for employees (e.g. showers, a half - basketball court) and is encouraged to make a voluntary contribution to the Parks Department to off -set potential impacts to area wide recreational facilities prior to the issuance of occupancy permits. FIRE PROTECTION The City of Renton Fire Prevention Bureau has noted that the project is in a location that exceeds the 4- minute maximum response time for Aid service and a 5- minute maximum response time for Fire assistance. The proposed facility is located in a response area of over 7- minutes. According to the Grading Schedule for Municipal Fire Protection issued by the Insurance Office, fire stations should be located within 1 1/2 miles of the proposed development. The closest existing fire station is located 2.8 miles from the proposed development. Staff are therefore recommending that the applicant contribute towards the cost of constructing a new fire station in this area. SANITARY SEWER SERVICES The EIS indicates that the project will not have a significant adverse impact of sanitary sewer service. The applicant will need to extend existing sewer lines to the project site in compliance with City Codes and standards. WATER SERVICE The EIS indicates that the project will not have a significant adverse impact on water service. The applicant will, however, need to extend water lines to the project site in compliance with City Codes and standards. RECOMMENDATIONS: 39) The applicant shall, in order to mitigate on -site recreational impacts, provide revised drawings prior to the issuance of building permits showing shower facilities and recreational facilities (e.g. a half - basketball court) on the project site. 40) The applicant is encouraged to make a voluntary contribution to the City of Renton, Community Services Department funds to off -set the project impacts to area recreational facilities. 41) The applicant shall review the proposed Master Trails Plan with the Community Services Department and the applicant is encouraged to incorporate the trail plans into the site design. 17 • • • • 42) The applicant shall, in order to reduce the emergency vehicle response time, execute an agreement with the City of Renton Fire Department to provide a fair - share of the cost to construct a fire station in the Green River Valley area.

SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS No significant adverse impacts to recreational facilities or City utility services are expected. J. HISTORIC AND CULTURAL RESOURCES The EIS reviewed the potential for adverse impacts to cultural and historic resources by the development of the proposed project. The Cultural Resources Assessment, dated April 2, 1991, was prepared by Larson Anthropological /Archaeological Services. As part of this assessment the Muckleshoot Tribe was contacted by phone and by letter. Although the proposed site is in an area that has been the scene of an ethnohistoric Indian population followed by a number of historic activities, no archaeological sites or culturally significant historic structures were identified after a careful check of records and field inspections. RECOMMENDATION: 43) The applicant shall, in order to prevent adverse impacts to historic and /or cultural resources, if cultural resources are identified during subsurface excavations associated with project construction, halt all construction in an area large enough to maintain integrity of the resources and hire a professional archaeologist to monitor all operations and shall notify the State Office of Archaeology and Historic Preservation and the Development Services Division.

REVIEW AND LICENSING A number of mitigation measures have been established for this project to ensure that it does not adversely impact the environment or area residential development. In order to ensure that this measures are effective, a monitoring program has been proposed. This monitoring program will allow the City to evaluate the effectiveness the mitigation measures and identify any additional measures that could be required. The City will also be issuing a license for this business. If the applicant does not comply with any of the proposed mitigation measures or operates this facility in a manner that is not acceptable to the City of Renton, than the license could be revoked. 46) The applicant shall provide a covenant and easements requiring it, future purchasers, assignees, successors in interest or lessees, to allow the City of Renton to annually review the proposed development's performance in landscape maintenance, noise mitigation, litter control, street cleaning, air quality, wet lands, control of waste stream, hauling limitations and traffic mitigation. The cost of this program shall be borne by the applicant and the annual fee for the services provided by the City of Renton shall be set at 150% of the City's total expenditure in these areas during the previous year plus the cost of the annual performance monitoring. The total expenditure would include, but not be limited to, Code inspections, monitoring programs and physical activities (e.g. street sweeping). These covenants and easements shall be approved by the City Attorney and the Development Services Division prior to issuance of any site preparation /building permits. The monitoring program will be initiated one year from the date of the issuance of occupancy permits and shall remain in effect for the life of the project unless both the City and the applicant mutually agree that a particular element is no longer required. This monitoring program shall include all other monitoring requirements discussed in this mitigation document. The covenant and easement shall be submitted in a form acceptable to the City Attorney. 19 • • • • 47) The applicant shall obtain from the City of Renton an annual license to operate the proposed facility. This license shall be renewed annually upon completion of the annual monitoring program if, in the City's opinion, the operator of the facility has complied with all of the mitigation measures and requirements. Denial of the annual license shall be cause for requiring the facility to be closed until remedial actions have been completed to the satisfaction of the Development Services Division. The cost of the annual license shall be borne by the applicant, future owners, lessees, assignees, or successors in interest.

Black River Waste Recovery Center and Shinnine Yard Draft Environmental Checklist 1 July 17, 1990 8. List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. Roosevelt Demolition and Inert Waste Landfill Supplemental Environmental Impact Statement Rabanco is constructing a regional landfill in Klickitat County, Washington. The Klickitat County Solid Waste Project FEIS was prepared in connection with the landfill permit applications. The Klickitat County Planning Department was lead agency for the FEIS, and the responsible official was David Kunz, Klickitat County Director of Planning. 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. No. No other applications are pending for governmental approvals of other proposals directly affecting the subject property. 10. List any government approvals or permits that will be needed for your proposal, if known. Building Permit, City of Renton Seattle -King County Department of Health, General Solid Waste Facility Permit Metro Industrial Waste Discharge Permit NPDES Permit for discharge of stormwater to Duwamish River. 11. Give a brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) The Black River Waste Recovery Center and Shipping Yard would be part of a system intended to manage construction, demolition, and landclearing debris (CDL) from projects in King County. This facility would be a recycling and transfer operation employing manual and mechanical processes to remove recyclable material from CDL wastes, process some of the recyclables, package others for delivery to processing facilities, and package the remaining wastes for shipment to a disposal facility. A 150 by 300 foot 48 -foot -high building would be erected on the site. The facility would also include an 8 -acre yard, a rail spur running alongside with a working length of 1800 feet, and two container storage areas totaling about 15,000 square feet. Trucks hauling waste to the facility will enter and exit on Steel Hill- Monster Road (68th Avenue South). Access to the site would be provided from Steel Hill - Monster Road on a ramp leading down into the site. The ramp would be paved and the adjoining slopes Black River Waste Recovery Center and Shinnine Yard Draft Environmental Checklist 2 July 17, 1990 • • reinforced with rock. Waste would be delivered between the hours of 6am and 8pm weekdays, and between 8am and 8pm Saturdays. King County estimates a total volume of 150,000 cubic yards per month of this type of material. That estimate, however, includes volumes generated within the City of Seattle. Seattle is in the process of contracting for material generated within its jurisdiction to be handled at facilities within Seattle. In addition, loads of concrete, asphalt, clean dirt, and vegetation will be diverted to other facilities. Therefore, an estimate of 115,000 cubic yards of material per month is likely to be processed at this facility in the first year. Within the building to be constructed on the site, waste will be separated into recyclable and nonrecyclable components. Recyclable components, including some concrete, asphalt, clean wood waste, cardboard, scrap metal, and, if possible, sheetrock, will be sorted and delivered to appropriate recycling facilities. Loads containing just concrete, asphalt, clean dirt, or vegetation will be instructed to go directly to other permitted facilities, including Stoneway Concrete Recycling and Cedar Grove Composting. Nonrecyclable components which meet the requirements for a demolition waste landfill (i.e., nonbiodegradable wastes that will not produce significant amounts of gases or leachate) will be loaded into open -top containers staged below the tipping floor at the corners of the building. Prior to loading, the material will be compacted as much as possible by equipment, such as a truck loader. After the material has been loaded into the container, a grapple hook on a hydraulic arm will be used to further compact the load. Full containers will be covered with an appropriate (e.g., canvas) cover. The container will be pulled out of its staging area within the building by a truck -like vehicle called a yard goat. The yard goat will pull the full- covered container to a place next to a railroad spur on the site. A rubber -tired vehicle, called a top -pick, will lift the container from the chassis upon which it has been riding and place the container on a railroad flat car. An empty container will be placed on the chassis and the yard goat will stage the new container inside the building. Rail cars will periodically be removed from the spur on the site by a switching engine and taken to available Burlington Northern Railroad staging areas in South Seattle until a full train is assembled. An average of one train would be assembled every day. The full containers would be shipped to a transfer station in Roosevelt, Klickitat County. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project site is located on the west side of Steel Hill- Monster Road, just north of its crossing of the Black River, adjacent to Stoneway Rock and Recycling, and immediately across the street from Renton Concrete Recycling. The property is located in the E y, SE 1, Section 14, Township 23N, Range 4E W.M. The total area of the site is about 13.5 acres. Black River Waste Recovery Center and Shipping Yard Draft Environmental Checklist 3 July 17, 1990 • • The following attachments have been included with this checklist: • visual assessment • traffic impact analysis • vegetation analysis • tree cutting /land clearing plan • site plan • landscaping plan • neighborhood detail plan • architectural elevations • operating plan • letter from Burlington Northern Railroad • letter from City of Renton, Community Development Department TO BE COMPLETED BY APPLICANT B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site (circle one): ( la rolling, hilly, steep slopes, mountainous, other b. What is the steepest slope on the site (approximate percent slope)? The steepest slopes occur adjacent to Steel Hill- Monster Road, Beacon -Coal Mine Road, and the adjacent railroad line. In these areas, the slopes exceed 25 percent. Steep slopes also occur along several berms crossing the site from northeast to southwest in the northwest third of the site. The remainder of the site is flat or slopes gently to the southeast. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. Topsoil has been removed from much of the site by previous gravel mining operations. The underlying soil is mostly fill ranging from silty to gravelly loams, and silt to silty clay. Some fill from adjacent gravel operations has also been recently deposited on the site. Hydric soils exist on portions of the northwestern third of the site. These soils range from sands to clays. The latter may be remnants of the original alluvial soil in the area. • d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. There are no surface indications or history of unstable soils in the immediate vicinity. The steep slopes around the edges of the site show no signs of instability. Black River Waste Recovery Center and Shinning Yard Draft Environmental Checklist 4 July 17, 1990 1 e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. Approximately 50,000 cubic yards of granular base material would be brought on -site to raise the site level and provide a firm base for operations for the proposed building, the proposed railroad siding, and the access roads. The source of the fill would probably be adjacent gravel operations. Grading would occur to construct sedimentation ponds. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Due to the flat terrain on the portion of the site that would be developed, erosion would be minimal. Some erosion may occur during widening of the access road. The steep slopes along Steel Hill- Monster Road would be reinforced with rock, reducing erosion in this area. g. About what percent of the site would be covered with impervious surfaces after project construction (for example, asphalt or buildings)? About 45,000 square feet of the site would be covered by the proposed building, 5,000 square feet by the scale, and a total of 15,000 square feet by the container storage areas. The rest of the working area of the site would be paved. About 90% of the site would be covered with impervious surfaces. h. Proposed measures to reduce or control erosion, or other impacts to the earth if any: In the case of construction activities during wet weather on the steeply sloping borders of the site, standard temporary erosion and sedimentation control procedures would be implemented. These include the use of siltation fences or hay bales downslope of construction to slow runoff and trap water -borne sediments. 2. Air a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. There would be vehicular emissions from construction equipment and truck traffic during operation of the facility. Handling of material, including compaction, will occur within the building. Measures to control dust, including fog - misters, and regular maintenance activities will prevent any fugitive dust emissions. b. Are there any off site sources of emissions or odor that may affect your proposal? If so, generally describe. No. No off -site sources of emissions or odor are present in the area which could affect the proposed project. Black River Waste Recovery Center and Shinnine Yard Draft Environmental Checklist 5 July 17, 1990 • • c. Proposed measures to reduce or control emissions or other impacts to air, if any: None. All potential dust generation will occur within the building. All outdoor working areas will be paved. 3. Water a. Surface 1) Is there any surface water body on or in the immediate vicinity of the site (including year -round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The nearest year -round bodies of water are the Duwamish and Black Rivers. The Duwamish River lies approximately 250 feet or more southwest and south of the site. The Black River lies more than 200 feet south of the site. In addition, surface runoff forms intermittent small ponds (totaling less than 1,000 square feet) along the southwest boundary of the site, below the railroad tracks. Three wetland areas exist on the northwest part of the site, separated from each other by berms and abandoned road grades; cumulatively they take up approximately 0.5 acre. Runoff from the site is through the northwest corner by way of a culvert to the Duwamish River. 2) Would the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. The project would not require any work over, in or adjacent to the Black or Duwamish Rivers. The wetlands are physically separated from the working area of the project by existing berms, but disturbance of approximately 5,000 square feet of wetland will be required to build the sedimentation ponds for storm runoff in the northwest corner of the site. The project will require filling some or all of the pond area between the site and the railroad tracks. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. Portions of the intermittent ponds will be filled during construction of a spur rail line to the facility. The amount of fill would be less than 500 cubic yards. No other fill or dredge material would be placed in or removed from surface water or wetlands as a result of this proposal. 4) Would the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No. No surface water withdrawal or diversion would occur as a result of this project. Black River Waste Recovery Center and Shinning Yard Draft Environmental Checklist 6 July 17, 1990 • • • 5) Does the proposal lie within a 100 -year floodplain? If so, note location on the site plan. No. The site does not lie within a 100 -year floodplain. The Duwamish River floodplain does not extend east of the railroad tracks that border the southwest side of the site. The Black River floodplain does not extend north of the railroad tracks that border the south corner of the site. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. No. The proposal does not involve any discharge of waste materials to surface waters. b. Ground: 1) Would ground water be withdrawn, or would water be discharged to ground water? Give general description, purpose, and approximate quantities if known. No. No ground water would be withdrawn and no water would be discharged to ground water. 2) Describe waste material that would be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals ...; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. No waste material would be discharged into the ground from septic tanks or other sources. c. Water Runoff (including storm water): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where would this water flow? Would this water flow into other waters? If so, describe. Runoff would be generated by precipitation. Runoff from impervious surfaces on -site would be collected by a storm drainage system and routed through an oil -water separator and 200 feet of vegetated sedimentation ponds at the northwest corner of the property to an outfall which leads to the Duwamish River. 2) Could waste materials enter ground or surface waters? If so, generally describe. No. No waste materials would enter ground or surface waters. Black River Waste Recovery Center and ShiDaing Yard Draft Environmental Checklist 7 July 17, 1990 d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: No measures are proposed, because no significant impacts are anticipated. 4. Plants a. Check or circle types of vegetation found on the site: ▪ deciduous tree: alder, maple, aspen, other evergreen tree: fir, cedar, pine, other _X_ shrubs - grass pasture crop or grain wet soil plants: cattail, buttercup, bulrush, skunk cabbage, other water plants: water lily, eelgrass, milfoil, other other types of vegetation b. What kind and amount of vegetation would be removed or altered? Vegetation exists in the northwest third of the property and along the southwest . edge of the site. There is no vegetation on the remainder of the site. Development of the site will require removal of approximately 1 acre of alder and associated trees and brush on the north edge of the project site and approximately 5,000 square feet of wetland vegetation in the northwest corner of the site. A minor amount of highly disturbed vegetation would be removed where fill would be placed for a spur track adjacent to the rail line. c. List threatened or endangered species known to be on or near the site. No threatened or endangered plant species are known to be on or near the site. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: Trees will be planted along Steel Hill- Monster Road and along the portion of Beacon -Coal Mine Road adjoining the site. 5. Animals a. Circle any birds and animals which have been observed on or near the site or are known to be on or near the site: birds• et eagle, n irds other. ma •' : deer, bear, elk, r, other: fish: bass, salmon, trout, herring, shellfis Black River Waste Recovery Center and Shipping Yard Draft Environmental Checklist 8 July 17, 1990 • • b. List any threatened or endangered species known to be on or near the site. No endangered or threatened animal species are known to be on or near the site. c. Is the site part of a migration route? If so, explain. The site lies in the Duwamish River valley, which is a migration route for birds and anadromous fish. Due to the isolation of vegetated areas from the Duwamish River, the site is not important to animal migration. d. Proposed measures to preserve or enhance wildlife, if any: A blue heron rookery is located approximately .25 mile east of the site along the Black River and near the Burlington Northern tracks. Trains will be made (cars linked together) on Burlington Northern tracks in South Seattle, not on the tracks near the heron rookery. Loading and unloading of waste on the site, and train - making activity will not disturb the heron rookery. No significant impacts to wildlife are anticipated, and no other mitigation measures are proposed. 6. Energy and Natural Resources a. What kinds of energy (electric, natural gas, oil, wood stove, solar) would be used to meet the completed project's energy needs? Describe whether it would be used for heating, manufacturing, etc. Petroleum would be used to power vehicles used in transporting material to the site, separating materials into recyclable and nonrecyclable components, and loading material onto rail cars and trucks on the site. The proposed building would not be heated, except for' a locker room and a driver's room. Electricity would be used for lighting and heating. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. No. This project would have no effect on the use of solar energy by adjacent properties. c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any: Due to the minimal use of energy sources, no measures are proposed to conserve energy. Black River Waste Recovery Center and Shianina Yard Draft Environmental Checklist 9 July 17, 1990 • • 7. Environmental Health a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so, describe. No. Waste materials brought to the site would be nontoxic, nonreactive, nonvolatile, nonflammable, and nonexplosive. 1) Describe special emergency services that might be required. No special emergency services would be required. 2) Proposed measures to reduce or control environmental health hazards, if any: No environmental health hazards are expected. Measures to control dust, including fog - misters, and regular maintenance activities will prevent any fugitive dust emissions. b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic equipment, operation, other)? No types of noise exist in the area that would affect this project. 2) What types and levels of noise would be created by or associated with the project on a short -term or a long -term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. Noise would be created by truck traffic travelling to and from the site, and from separation and loading operations on the site. Noise would also temporarily be created by construction activities on the site. Existing noise on the site is highest during passage of trains nearby. Noise also is generated by gravel pit operations on the other side of Steel Hill- Monster Road. During operations, noise from truck traffic and from on -site operations would occur between the hours of 6am and 8pm on weekdays and 8am and 8pm on Saturdays. Predicted noise levels from the types of trucks and loading equipment that would be used in this project range up to approximately 84 dBA at 50 feet. Increased noise would be most noticeable at the Foster Golf Course, whose closest point is about 250 feet across the railroad tracks from the site, but noise levels at the golf course would be within allowable limits under Renton noise regulations. Noise levels at the nearest residences, over 600 feet away across the Duwamish River, would also be within allowable limits. Noise from the site would be attenuated both by distance and by vegetation, since the site is partially shielded by the adjacent railroad grade and the trees growing on the edge of the property. Black River Waste Recovery Center and Shippine Yard Draft Environmental Checklist 10 July 17, 1990 • • 3) Proposed measures to reduce or control noise impacts, if any: Unloading, separation, compacting, and reloading will all occur within the building. No other measures are proposed to reduce noise impacts, since these are not expected to be significant. 8. Land and Shoreline Use a. What is the current use of the site and adjacent properties? The site is vacant, was previously used for gravel excavation, and is currently used for storage of materials from adjacent gravel operations. Property to the northeast of the site is occupied by Renton Concrete Recycling and Stoneway Rock and Recycling. Property to the south and southwest of the site is occupied by railroad tracks. Property farther north from the site is mixed light industrial and residential. Part of Foster Golf Course lies to the northwest, across the railroad tracks. A residential area is located on bluffs to the southwest, across the Duwamish River. A warehouse is to the south, across the railroad tracks. A manufacturing park lies to the southeast, across the Black River. A gravel pit and open space lie to the east. b. Has the site been used for agriculture? If so, describe. No. The site has not been used for agriculture. c. Describe any structures on the site. Two small wood frame one -story buildings exist on the southeast corner of the site, adjacent to Steel Hill- Monster Road. d. Would any structures be demolished? If so, what? No buildings will be demolished during site development. e. What is the current zoning classification of the site? The site is zoned L -1 ( "Light Industry") by the Renton Zoning Code. Recycling collection stations or centers are a specifically permitted use under this designation. Another specifically permitted use under this designation is "Manufacturing, processing, assembling, and packaging of articles, products, or merchandise from previously prepared or synthetic materials." The City of Renton (letter attached) has made a determination that the proposal falls under the latter definition. f. What is the current comprehensive plan designation of the site? The site is designated for light industrial use. Black River Waste Recovery Center and Shiapine Yard Draft Environmental Checklist 11 July 17, 1990 • • g. If applicable, what is the current shoreline master program designation of the site? Not applicable. The site is not within designated shoreline. h. Has any part of the site been classified as an "environmentally sensitive area? If so, specify. No. No part of the site has been classified as "environmentally sensitive." i. Approximately how many people would reside or work in the completed project? Five to twenty people would work on the site at any one time. j. Approximately how many people would the completed project displace? The project would not displace any people. k. Proposed measures to avoid or reduce displacement impacts, if any: None. No measures are required. 1. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any: The proposed facility is consistent with existing land uses, comprehensive plan designations, and zoning. The building would be set back 200 feet from Steel Hill - Monster Road. The proposal would be consistent with existing land uses in the vicinity. 9. Housing a. Approximately how many units would be provided, if any? Indicate whether high, middle, or low- income housing. No housing units would be provided. b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle, or low - income housing. No housing units would be eliminated. c. Proposed measures to reduce or control housing impacts, if any: None. No housing impacts would occur. Black River Waste Recovery Center and Shippin¢ Yard Draft Environmental Checklist 12 July 17, 1990 • • 10. Aesthetics a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s) proposed? A 150 x 300 foot building about 48 feet high made of prefabricated metal would be placed on the site. b. What views in the immediate vicinity would be altered or obstructed? An alteration of views would be caused by the proposed building, which would resemble a warehouse. Views from the part of Steel Hill- Monster Road adjacent to the site would be partially obstructed by the proposed building. No other views would be obstructed. Views from the adjacent gravel pit that include the now vacant site would be altered when the site develops. The proposed building would also be visible from some areas to the south, west, and northwest. In many cases, views would be screened by trees. The proposed building would be more visible from the Foster Golf Course. The building would also be visible at a distance from a number of apartment buildings and residences in Tukwila, although it would be partially screened by trees in many cases. However, the proposed building would not significantly alter these views because of its low elevation, the prominence of the adjacent gravel pit behind it, the distance of separation, and the height of surrounding hills. c. Proposed measures to reduce or control aesthetic impacts, if any: Because there would be no significant alteration of views, no mitigation measures are proposed. 11. Light and Glare a. What type of light or glare would the proposal produce? What time of day would it mainly occur? The loading yard on the site would be lighted early and late during daily operations. Trucks entering and leaving the site early or late during daily operations would produce light from headlights. Time of operations would be 6 am to 8 pm. The times that light would be produced during this daily period would depend on the season, with the maximum periods occurring in winter when lighting may be produced for about 2 hours in the morning and 4 hours at night. Some additional glare at the site would be produced by reflection from the walls of the proposed facility during daylight hours. Black River Waste Recovery Center and Shinning Yard Draft Environmental Checklist 13 July 17, 1990 • • b. Could light or glare from the finished project be a safety hazard or interfere with views? No safety hazards or interference with views from light and glare are expected. c. What existing off site sources of light or glare may affect your proposal? No existing off-site sources of light or glare would affect this proposal. d. Proposed measures to reduce or control light and glare impacts, if any: All on -site lighting would be shielded and directed toward the site. Because of the isolation of the site from residential areas, no other measures to reduce light and glare are planned. 12. Recreation a. What designated and informal recreational opportunities are in the immediate vicinity? No designated or informal recreational opportunities exist adjacent to the site. Two golf courses lie near the site, as well as a Tukwila city park. Access to Fort Dent Park and Foster Golf Course is far from the site; both are separated from the site by over 200 feet of railroad tracks. Access to Earlington Golf Course is about OS miles southeast of the site on Steel Hill- Monster Road. A wildlife recreation area is located about 0.5 miles east of the site. Informal recreational opportunities in the neighborhood of the site include canoeing on the Duwamish River (250 feet or more from the site) and walking along the Black River (400 feet south of the site). b. Would the proposed project displace any existing recreational uses? If so, describe. No. The proposed project would not displace. any existing recreational uses. c. Proposed measures to reduce or control impacts, if any: None. Minimal impacts relating to recreation would occur. 13. Historic and Cultural Preservation a. Are there any places or objects listed on, or proposed for, national, state, or local preservation registers known to be on or next to the site? If so, generally describe.

There are no landmarks or evidence of historic, archaeological, scientific, or cultural importance known to be on or next to the site. c. Proposed measures to reduce or control impacts, if any: None. No impacts to historic or cultural artifacts are expected. 14. Transportation a. Identify public streets and highways serving the site, and describe proposed access to the existing street system. Show on site plans, if any. About 90 to 95% of the trucks bound for the site would arrive by way of I-405 to the south. Access would be by way of Steel Hill- Monster Road, which borders the east edge of the site. This street has gravel shoulders and about a 20 to 22 foot paved cross- section. b. Is site currently served by public transit? If not, what is the approximate distance to the nearest transit stop? No. The site is not served by public transit. The nearest transit stop is approximately 0.5 miles away on Martin Luther King, Jr. Way. c. How many parking spaces would the completed project have? How many would the project eliminate? The site would provide sufficient parking for up to 20 people working at the facility. No parking spaces would be eliminated by the project. d. Would the proposal require any new roads or streets, or improvements to existing roads or streets, not including driveways? If so, generally describe (indicate whether public or private). No new roads or streets or improvements to existing roads or streets would be required. e. Would the project use (or occur in immediate vicinity of) water, rail, or air transportation? If so, generally describe. The project occurs adjacent to Burlington Northern and Union Pacific railroad tracks and would use rail transportation to ship demolition waste to Klickitat County. Waste would be loaded onto rail cars on a spur to be constructed into the loading yard. Black River Waste Recovery Center and Shipping Yard Draft Environmental Checklist 15 July 17, 1990 • • f. How many vehicular trips per day would be generated by the completed project? If known, indicate when peak volumes would occur. A maximum of 900 truck and 60 automobile trips would be generated per day. Seventy to 80% of the trips would occur between 9 am and 3 pm. About 24 trips, 12 truck and 12 auto, would occur during the afternoon peak hour (see the attached Traffic Impact Analysis). g. Proposed measures to reduce or control transportation impacts, if any: Sight distance to the south is somewhat restricted but could be mitigated by installation of a vehicle warning light on Steel Hill- Monster Road that would be activated by trucks preparing to leave the facility. This light would be paid for by the proponent. The proponent would be willing to contribute to road maintenance and other costs due to increased traffic, in proportion to the contributions made by other firms in the adjacent traffic benefit area. Finally, the proponent would be willing to pay a portion of road reconstruction costs along Steel Hill- Monster Road, based on the proportion of traffic generated by the project (see the attached Traffic Impact Analysis). 15. Public Services a. Would the project result in an increased need for public services (for example: fire protection, police protection, health care, schools, other)? If so, generally describe. No. The project would not result in an increased need for public services. b. Proposed measures to reduce or control direct impacts on public services, if any. None. Additional public services would not be needed. The waste would be nonvolatile and nonflammable. It would not include liquids or dangerous waste. 16. Utilities a. Circle utilities currently available at the site: electricity, natural gas, water, refuse service, telephone, sanitary sewer, septic system, other. b. Describe the utilities that are proposed for the project, the utility providing the service, and the general construction activities on the site or in the immediate vicinity which might be needed. Electrical service (Puget Power) will be required by this facility and is already available onsite. As part of the project, water service from the City of Renton and sanitary sewer service would be installed. A looped water line would be constructed on the site, as well as a sewage lift station. Linkage to the water and sanitary sewer systems will require installation of approximately 0.5 mile of water and sewer lines.

This analysis presents the vehicular traffic elements of an environmental checklist for this proposal. The purposes of this analysis are to identify any traffic related impacts generated by the construction and operation of the proposed project and, where warranted, to outline policies, programs and /or physical improvements to minimize or eliminate the effects of these impacts. Project Location The project site is located in the westernmost section of Renton, Washington as shown on Figure 1. The site is bounded on the east by 68th Avenue South and on the west and south by the Union Pacific Railroad tracks. The Stoneway Rock and Recycling facility is located to the east and across the street from the subject site. The site access is proposed to be off 68th Avenue South The entrance and exit driveway is located south of the existing scale house opposite Stoneway Rock and Concrete Recycling and can serve traffic traveling either northbound or southbound on 68th Avenue South. Project Description This Renton Demolition Center is proposed to be a sorting and transfer facility for construction, demolition and landclearing (CDL) wastes. Recyclable portions of the waste such as metal, wood, and concrete will be sorted and transported to their respective recycling facilities (e.g. Stoneway Concrete Recycling). Non - recyclable and non - biodegradable wastes will be compacted into containers, then loaded onto rail cars and transported to the Klickitat Regional Landfill. Presently, these wastes are being transported to landfills in King County with the majority being transported to the Newcastle site. A site plan for the proposed project is presented on Figure 2.

This facility is targeted to serve the South King County area. Seattle and areas to the north will be served by another similar transfer site in Seattle at Third Avenue and Lander Street. Study Process The process used in preparing this traffic analysis follows a generally accepted, three step methodology. The analysis and report is formatted to first discuss existing traffic conditions which provides an existing framework or reference for the remainder of the analysis. Next, future conditions without the proposed project are forecasted to establish a baseline against which to measure the project- specific traffic related impacts. Then, project - generated traffic forecasted and superimposed on non - project traffic to evaluate impacts precipitated by this proposal. Finally, a summary of impacts is listed and combined with a series of mitigating measures that are intended to reduce or eliminate the effects of potential adverse impacts. • • EXISTING CONDITIONS This section of the report describes the existing transportation conditions in the vicinity of the proposed Renton Demolition Center and includes a description of the street system and traffic volumes and conditions in the vicinity of the site. This information is intended to provide an informed basis for evaluating and accurately interpreting forecasted traffic conditions. Street Network The street system in the area does not follow any precise pattern, because many of the major streets have been aligned to adapt to the steep slopes, wetlands, and rivers which typify the area. Like the remainder of King County, "Avenues" generally run north and south while "Streets" are oriented east and west. 68th Avenue South is a 20 to 22 foot wide paved road which provides road access to the site. This road follows a winding alignment that falls from its intersection with Martin .Luther (M.L.) King Way at grades that vary from an estimated 0% to 6% and crosses a two -lane bridge as it levels out on the valley floor. The combination of horizontal and vertical road alignment at the south end of the site limits sight distance along the bridge for vehicles traveling northbound. As the road realigns, the name changes to South 43rd Street and then to Oaksdale Way as shown on Figure 3. Oaksdale Way is a four -lane divided roadway that accommodates five lanes at its intersecting cross streets. This major arterial was constructed as part of the Earlington and Black River Office Park projects and extends south across Grady Way to Longacres Race Track. Grady Way is a four to five -lane arterial that has recently been rebuilt and serves as one of the few continuous east -west links across Renton. This road provides a linkage to Interstate -405 (I -405) via Rainier Avenue (State Route 167) to the east and Interurban Avenue (West Valley Highway) to the west. S 2N0 ST RD ST 4 N LEG E N D rz Traffic Signal 4L Four Lanes Stop Sign TSI FIGURE 3 Transportation SolationsInc EXISTING STREET SYSTEM RENTON RABANCO • • M.L. King Way is a four -lane major arterial that connects south central Seattle with Renton. The grade along this section . of the roadway is essentially zero and sightlines are good in both directions from the intersection at 68th Avenue South. Traffic Control is provided by traffic signals at most of the intersections along the arterials in the area, including the roads described above. One exception is 68th Avenue South at its intersection with M.L. King Way which is stop sign controlled, forcing traffic on 68th Avenue South to wait for gaps in the traffic on M.L. King Way. Traffic Volumes and Patterns Current traffic volume information was assembled from the City of Renton, City of Tukwila, and the Washington State Department of Transportation (WSDOT) at key intersections. A summary of the PM peak hour volumes is presented on Figure 4. PM peak hour volumes were examined because the combination of project generated and background traffic volumes were highest at this time of the day. Furthermore, PM peak hour traffic volumes are traditionally 15% to 45% higher than other mid -day or AM peak hour traffic volumes. This relationship is particularly the case in this area due to the combination of commuter, shopping, and Longacres related trips in the vicinity of the site. Traffic Analysis To analyze the PM peak hour traffic volumes, a Level of Service (LOS) analysis was performed at these intersections to quantify the current level of intersection operation. The intersection LOS typically dictates the traffic operations of the surrounding street system. These LOS techniques have been developed to assess the level of congestion by calculating the average vehicle delay at signalized intersections and determining the reserve capacity at unsignalized intersections. The most generally accepted techniques are described in the 1985 Highway Capacity Manual and • Q N 1'SI Transportation Solotions Inc. FIGURE 4 EXISTING TRAFFIC VOLUMES (PM PEAK HOUR) RENTON RABANCO • use a grading system that ranges from LOS -A, which is very good, to LOS -F, which reflects a forced flow condition. When comparing the results of these level of service analyses it is important to compare the change in average vehicle delay and reserve capacity since this is the true measure of change in the LOS. The results of the LOS analysis are summarized in Table 1 and show that all intersections operate at LOS -C or LOS -D except the high volume intersections of Rainier Avenue at Grady Way and the southbound I -405 Ramps at the West Valley Highway which both operate at LOS -F. The LOS -F condition at the Rainier Avenue /Grady Way intersection is the result of the convergence of several high volume, major arterials: I -405, the Valley Freeway (SR 167), and Grady Way. The intersection geometry has been optimized with multiple turn lanes and exclusive /channelized turn lanes. The. LOS -F condition at the southbound I -405 ramps /Grady Way /Interurban Avenue intersection is the result of a similar convergence of high volume roads, as well as the increased volume associated with the Longacres Race Track. The LOS -F associated with the left turn movements from 68th Avenue South onto M.L. King Way is not reflective of field observations of the delay experienced at this intersection. This difference is commonly observed because: 1) the HCM methodology is generally conservative in relation to the assumed acceptable gap for left turn movements; and 2) the HCM analysis does not accurately reflect the effect of multilane roads with non - random flow conditions. Based on these observations, the LOS for the northbound left turn movement is estimated to operate more closely to LOS -D. • • FORECASTED TRAFFIC CONDITIONS This section of the report outlines the assumptions and steps taken to arrive at an estimate of future traffic for the proposed Renton Demolition Center. It provides an understanding of future conditions without the project so an accurate assessment of future traffic conditions with the project can be made. For the purpose of this analysis, 1992 was selected as the time when the facility would be constructed and in full operation. While the waste stream flow may not be at a maximum in 1992, the maximum capacity for the facility was assumed to reflect a "worst case" traffic condition. The forecasted travel demand on streets in the vicinity of the site is composed of three primary elements; 1) existing traffic; 2) future non - project traffic; and 3) project - generated traffic. Existing traffic volumes were presented earlier in the report on Figure 4. Future non - project traffic volumes are the incremental increase in volumes which is expected to occur between now and 1992, but which have no direct relationship with the operation of the Renton Demolition Center. Project - generated traffic volumes, as the name implies, are those volumes that are expected to be generated by trucks hauling CDL waste to the facility, trucks hauling recyclables from the facility, and by employees working at the facility. Non - project Traffic Volumes Future non - project traffic volumes were developed using historical traffic growth trends to adjust the existing traffic volumes upward by two to five percent per year. The resulting volumes at major intersections are summarized on Figure 5. A level of service analysis was again conducted to determine the effect of these non - project traffic volume increases and the results are presented on Table 1., This analysis shows a decline in the average vehicle delay or reserve capacity at every intersection. The intersection of Rainier • • Q N 9 S 2ND ST S 3R0 ST v 32 J 718 415 — 23 324 i 0 00 0 N zzzz AM 1s A .0 Ca N 219 165 411 . 619 150 ` 485 ts 1 N N 0 J � $ TSI Transportation Solutions Inc FIGURE 5 1992 TRAFFIC VOLUMES WITHOUT PROJECT RENTON RABANCO 1 1 • • Avenue at Grady Way continues to operate at LOS -F but the average delay could not be computed because the Volume to Capacity (V /C) ratio exceeded 1.2. Project - Generated Traffic The project - generated traffic volumes are composed of two primary groups: 1) truck traffic bringing waste to and carrying recyclables from the facility; and 2) employee trips. The truck traffic volume was forecasted using the actual traffic patterns associated with a similar recycling facility in Seattle using the CDL truck volume as a reflection of hourly patterns and average truck load factors. The waste volume was based on the maximum regional forecast of CDL waste, less the waste forecasted to be processed by the Seattle recycling facility and Snohomish County CDL waste. This results in a conservative (higher than may ultimately be processed) estimate because there are plans to build other CDL recycling facilities elsewhere in King County. In any event, this presents a worst case condition. Based on the forecasted volumes of waste, this facility is forecasted to serve up to 450 truck deliveries per day. These will involve a full range of open and drop container type trucks and translates to 900 one -way trips per day. The 10 to 20 employees are expected to generate an average of up to 60 one -way trips per day. This is based on the trip generation rate for trips per employee for heavy industrial type land uses as described in the Institute of Transportation Engineers Trip Generation Manual (4th Edition). Thus, a total of 960 one -way daily trips are expected to be generated by the project at full operation. While these daily traffic forecasts provide an understanding of the activity level within a given day, peak hour traffic volumes, as discussed earlier in the report, are more appropriately used to measure the true impact of a given project. Other similar facilities experience their highest traffic volumes between the hours of 11:00 am and 3:00 pm when • • about 70 percent of the waste is brought into the recycling site. This pattern coincides with the majority of commercial work schedules. Evenings and weekends are times when the majority of residential and non - commercial waste is brought into the site. The traffic patterns associated with transfer and commercial recycling facilities are typical of many industrial uses, in that the peak hour traffic volumes represent a smaller portion of the daily traffic volume than other land uses such as office or retail developments. The traffic patterns at other locations shows that less than two percent of the daily truck traffic is generated during the afternoon peak period. Based on other similar operations, the peak hour truck volume is estimated to be 12 one -way trips (6 trips in and 6 trips out). Employees will add another 12 trips (2 trips in and 10 trips out). Trip Distribution The majority, if not all of the trips generated by this site, will be oriented to and from the south because: 1) there is an existing facility that serves the demands generated to the north in Seattle; and 2) access to east and south King County is made more attractive by the convenient connections with I -405. The combination of these market and travel convenience characteristics leads to the conclusion that over 90 percent of the trips to and from the site will be oriented to the south. Thus, traffic generated by this project was assigned to routes leading to the south or to I -405. The 1992 PM peak hour traffic volumes with the proposed recycling facility are depicted on Figure 6. Traffic Volume Analysis The additional traffic volumes will add to the calculated delay at major intersections but the impact observed by the average driver is expected to be minimal. Even though heavy trucks have operating characteristics that have a proportionally -13- S 2ND ST D ST zz zz A Is .0 fl N N A r 219 " 411 619 152 (-485 .p v� 00 N d v r TSI Transportation Solutions Inc FIGURE 6 1992 TRAFFIC VOLUMES WITH PROJECT RENTON RABANCO -14- greater impact than an automobile, the volumes generated by this project are very small and will have a limited potential impact. The results of the LOS analysis (presented on Table 1) show that there is no change in the letter ratings of LOS and less than one second increase in delay due to the additional truck and employee traffic. This should be compared with the average six second increase in delay due to the growth in non - project traffic. The sub - regional distribution of the truck trips suggests that most will use I -405 and the regional freeway system with or without this project. This is because most of the trucks destined for the proposed facility will be generated within south and east King County and because many of these future trips are already traveling via the freeway system to east and south King County landfills that are near capacity and are proposed to be closed. Accordingly, there is not expected to be a noticeable impact on the freeway system. Taking a broader perspective, the introduction of this and similar transfer facilities has a benefit to the regional system by reducing the length and number of truck trips, particularly when the bulk of the residual waste is transported by rail. Thus, it is concluded that the introduction of this use will not have a noticeable adverse impact on the quality of traffic flow in the area. Other Traffic Issues An examination of sight distance was made along 68th Avenue South, and it was found that the curvature of the horizontal alignment, in combination with a slight down grade, results in restricted sight distance to the south when vehicles exit the site. This sight line restriction would affect trucks turning left out of the site. There is little concern about delay for trucks turning into the site because the scale house is located several hundred feet off the edge of 68th Avenue South; there are two queueing lanes; and the scales and record keeping systems do not require inbound trucks to stop for extended • • TABLE 1 LEVEL OF SERVICE SUMMARY SIGNALIZED LOS (Delay *) 1 1 1992 W/O 1 1992 W/ 1 !INTERSECTION 1 EXISTING 1 PROJECT 1 PROJECT 1 1GRADY WAY /RAINIER AVE IGRADY WAY /LIND AVE ;GRADY WAY /OAKSDALE PKY 1SW 7TH ST /OAKSDALE PKY 1 1NB 405/W VALLEY HWY 1 1SB 405 /INTERURBAN AVE F (80.9) D (26.2) D (34.4) C (15.6) D (37.1) F (74.3) V/C =1.237 D (30.5) D (37.4) C (15.8) E (54.8) F (90.2) V/C =1.240 D (30.5) D (38.3) C (15.7) E (55.4) F (90.2) * Average vehicle delay for the entire intersection. ** When the Volume to Capacity ratio (V /C) exceeds 1.2 the average vehicle delay can not be calculated and the overall V/C ratio can be used to measure the change in LOS.

Safe Stopping Sight Distance (SSSD) can be provided to the north from the driveway despite the break in the vertical grade of the road. To date, this sight line restriction and the existing access to Stoneway Rock and Recycling has not resulted in a safety hazard. Based on an examination of the road surface conditions in the area and recognizing the vehicle composition includes a high proportion of heavy trucks, the traffic generated by this proposal is not expected to have a noticeable adverse impact on the condition of the road surface along 68th Avenue South. For reference, Stoneway Rock and Recycling trucks haul loads that average at least twice the average density of the wastes that will be brought into the subject site. • SUMMARY OF IMPACTS AND POTENTIAL MITIGATION The following summarizes the anticipated impacts and mitigation that can be considered for inclusion as part of the proposed project. Traffic Volumes The analysis of traffic volumes indicates that this proposed project would have an insignificant effect on the quality of traffic flow in the area due to the low daily and PM peak hour traffic volumes. Although much of the traffic would involve large trucks, the bulk of this truck volume occurs during off -peak periods. Although this conclusion has been recognized by City staff, they note that the City of Renton has developed several Transportation Benefit Zones (TBZ) in an effort to equitably assess the costs associated with off -site road improvements. This concept has been developed to distribute the cost of off - site road improvements among all land developers; recognizing that each new development makes some contribution to the reduction in LOS on the roadway network, whether the road operates at LOS -A or LOS -F. In this area of the City, there is a graduated fee schedule based on the type of land use. This is a one time fee and is intended to mitigate all road system impacts in the area. These fees have been based on areawide road needs, and take into consideration the affect of bypass and diverted trips. The fee associated with industrial uses is $185 per daily one -way trip. When applied to this project, the one time project related contribution to off -site road improvements is calculated to be $177,600. Although this site falls just outside the boundaries of this TBZ, the majority of the project traffic passes through the TBZ area and thus impacts the assessed TBZ road network. Thus, it is suggested that consideration be given to making this contribution in lieu of any specific off -site road improvement(s). • Sight Distance Restrictions To address the sight line restriction and to provide safety for trucks exiting the site, it is recommended that a traffic actuated warning light system be installed on 68th Avenue South to warn northbound vehicles to lower their speed and be alert to trucks entering the road. It may be beneficial for Stoneway Recycling to join in this improvement since their driveway is located opposite the proposed driveway serving the project site. Heavy Truck Traffic Although there is not anticipated to be a problem with wear and tear on roads due to the additional heavy truck traffic, City staff have expressed concern regarding the potential for future problems. Thus, it is proposed that the TBZ assessment be applied to roads inside the TBZ that show excessive wear due to high volumes of truck traffic. Since the section of 68th Avenue South adjacent to the site falls outside the boundaries of the TBZ and is the most heavily impacted by the project truck traffic, it is suggested that the City and the applicant enter into an agreement where Renton Demolition Center will pay for their proportional share of the cost of road reconstruction on 68th Avenue South based on their daily traffic volume as a proportion of the total daily traffic volume. This proportional share shall be determined through an independent study. It is also suggested that the City consider making this a condition of other future uses along this section of 68th Avenue South Summary This analysis indicates this proposal would generate up to 960 one -way vehicle trips per day and up to 24 one -way trips during the afternoon peak hour. The majority, if not all of the trips, would be oriented to and from the south due to the market area served and the convenient access to I -405. The minor increase in traffic volumes is not expected to have a noticeable adverse impact to congestion along the roads leading to the site. Nonetheless, it is suggested the project sponsor pay the -19- • City an equivalent to the proportional share of areawide road improvements which is calculated to be $177,600. Due to a sight distance restriction created by the horizontal alignment of the roadway, it is also suggested that a warning signal system be installed to enhance traffic safety for trucks in the area. Finally, it is suggested that an agreement be developed between - the City and the Renton Demolition Center to pay for their proportional share of the cost of road reconstruction costs along the portion of 68th Avenue South which is inside the City limits but outside the TBZ and is impacted by the additional project generated heavy truck traffic. In summary, this analysis concludes that there is no reasonable probability of a significant adverse impact provide the measures outlined can be implemented as part of the project. • • Black River Waste Recovery Center and Shipping Yard Vegetation Survey For purposes of determining trees or vegetation to be removed within the City of Renton boundary, a site visit was conducted on July 9, 1990 to collect data on current vegetation existing on site. Particular attention was paid to numbers and species of trees greater than 6 inches in diameter at breast height (dbh). The entire site was traversed with counts of total numbers of trees (diameters were estimated) made on a series of one -tenth to one - quarter acre plots. Data presented in the attached table is partitioned into City of Renton and King County jurisdictional areas. Essentially all vegetation on the site within the City of Renton boundary is assumed to potentially require removal for buildings, retention walls, and construction activity zones. A few trees and some shrubby vegetation may be retained between the roadway and retention wall, but the portion of the site not covered by impervious surface will require landscaping following completion-of construction. Vegetation on the hillside is native, deciduous forest with scattered individuals and clumps of coniferous trees. Most of the site is dominated by big -leaf maple and red alder with wetter toeslope positions being dominated by black cottonwood. Coniferous species present are mostly Douglas -fir and western redcedar with a few sapling western hemlock appearing in the understory. Understory vegetation varies from very shaded conditions with no shrub or herbaceous species present to heavily vegetated wet depressions. Upland shrub communities are dominated by indian plum or common snowberry shrub layers with fringecup, swordfern, and various other forest species occurring at reduced levels in the herb layer. Three small wetland depressions, ranging from 0.01 to 0.03 acres in size, are dominated by a thick layer of dead leaves, horsetail, ladyfern, and /or youth -on -age.

The facility is a Recycling and Transfer operation employing manual and mechanical processes to remove recyclable material from CDL wastes, process some of the recyclables, package others for delivery to processing facilities, and package the remaining wastes for shipment to a disposal facility. The Black River facility is part of a system approach employed by Rabanco to manage CDL wastes. At the heart of the system is the Roosevelt Regional Landfill, a disposal facility located near Roosevelt in Klickitat County. The system also includes partnership with the Stoneway Concrete Recycling Company and use of Rabanco's Cedar Grove Composing facility. BLACK RIVER OPERATIONS: Wastes will be delivered to the CDL facility by various trucking firms, including Rabanco trucks and some residential traffic. Trucks will enter the facility at the far south of the property from 68th and proceed to the scale - house. After being weighed, the trucks will be directed to the entrance ramp of the building. There will be 12 -14 tipping stations along the ramp. The driver will be directed to dump the contents of the truck onto the tipping floor, which is located about 5 feet below the loading ramp. After dumping, the trucks will be directed to exit the site through the scale area. The exiting trucks will be reweighed and then exit back onto 68th. The scales are electronic and computer - operated. Most of the deliveries will be by companies that have billing arrangements with Rabanco, so the time at the scale - houses will be quite short. Workers will be stationed in the tipping area below the truck loading ramp. As material is dumped onto the tipping area, the workers will manually remove recyclable material and use construction vehicles to pull large amounts of recyclables to one side. They will manually pull out materials commonly found in CDL, such as cardboard, metals, and clean (unpainted and untreated) wood. The recyclables that are pulled out will be initially stored in staging areas inside the building and periodically moved to containers stationed below chutes at points along the perimeter of the building. The wood that is pulled out will be moved to an area where a chipper will be located. The laborers will be trained to identify potentially dangerous or hazardous materials. Marked metal containers will be placed within the tipping area for placement of such materials. These containers will be removed from the site by a hazardous waste treatment company. • • The recycled wood will be hand or mechanically fed into a chipper that will grind the wood into pieces of uniform size for use as fuel, ground cover, or in composting. The chipper will be fitted with a magnet to pull out metals such as nails. The chipped wood will be fed into a hopper located at the back of the building. Chipped wood will be loaded from the hopper into the back of trailers and taken to appropriate markets or processing facilities by truck. The other recyclables that have been placed in containers will also be taken by truck to appropriate markets or processing facilities. When all recyclables have been removed, the material will be prepared for transfer with a track loader (such as a D -6 Cat). The track loader will break up the remaining material, reduce its size and increase its compactability. The crushed material will then be pushed by the track loader into one of two chutes located along the perimeter of the building. Placed below the chutes, but still partially enclosed within the building, will be open -top containers sitting on a truck chassis. An hydraulic arm above each chute will be used to level the loaded materiai out and further compact it in the container. The full disposal containers will be covered with a canvas or rigid cover and pulled out of their staging areas below the chutes with a vehicle called a "yard goat ". The yard goat is a tractor -like, non -road vehicle. It has a very tight turning radius that allows for easy movement around the yard area. The vehicle is also relatively quiet compared to a semi - tractor pulling a full load at low speeds. The yard goat will remove the full trailer from its staging area, replace it with an empty container, and then deliver the full container to a rail spur at the back end of the facility. The container will be brought alongside a railroad flatcar. A rubber -tired machine called a "top- pick" or "top- loader" will be used to lift the container from the truck chassis and place it on the railroad flatcar. An empty container will be placed back on the chassis and will be moved by the yard goat to the loading areas for future use. When a train is not at the facility, the loading operation will vary slightly. The full containers will be stored in a designated area of the yard until the train arrives. When the train arrives at the facility, it will be loaded on a first -in; first -out basis. Full trains will be taken either directly to Roosevelt or to a rail yard in south Seattle for temporary storage until connected to another group of cars for transportation to Roosevelt. From Roosevelt, the material will be transloaded onto truck chassis and taken by truck to the Roosevelt Regional Landfill for disposal. DRAINAGE AND SURFACE WATER: CDL is nonputrescible material. Therefore, leachate will not be generated. The site will be drained into oil /water separators located on the site. The discharge from the oil /water separator will flow into a treatment /retention pond located at the far northwest end of the site. • • MONITORING PLANS /MAINTENANCE PLAN: The monitoring and maintenance of facilities and equipment that could effect the operation of the facility is addressed through a continual (24 hours per day, 7 days per week) cleaning and preventive maintenance program. The program consists of two phases: site cleanup and mechanical maintenance. Site Cleanup: Litter will be cleaned up by sweeping the outside surfaces of the facility at least every 24 hours. Sweeping will be accomplished by using a mechanical dry-brush sweeper. Additionally, the receiving area of the CDL facility will be swept and washed down with a fire hose fitted with a pressure nozzle as needed, but at least every 24 hours. Mechanical Maintenance: A team including electricians, welders, machinists, and maintenance mechanics will conduct scheduled periodic inspections and preventive maintenance of all facility equipment. Any problems that could lead to system failures will also be addressed at this time. This crew will also respond to system and equipment failures as they occur. Maintenance and repair activities will occur at the locations of stationary equipment to the extent possible. VECTOR /NOISE CONTROL: Vectors: Vectors are not anticipated to be a problem at the facility. Vectors are common concerns at municipal solid waste facilities. This is due to the fact that pests such as rats, pigeons, crows, and insects are attracted to the organic material (i.e., food wastes) commonly found in waste streams. Given the lack of putrescible materials in the CDL waste, there is little to attract these pests. Also, because all materials will be handled within the enclosed building, birds will be prevented from accessing the waste. In addition, the ongoing nature of the operation itself and plant maintenance (see Maintenance /Monitoring) will prevent the accumulation of vector attractors. The cleaning activities themselves will ward off any pests that might stray onto the site. Noise: Some potential noise problems are prevented in the same manner as vectors by having the operation occur within buildings. All dumping, sorting, compacting, and transferring activities occur within the CDL waste recovery building. Noise generation outside of the buildings will occur from trucks and operating equipment used for the various facility components. All equipment used at the site will be equipped with noise attenuating apparatus such as mufflers. Rabanco strives to obtain Best Available Control Technology (BACT) for all of its facility equipment. • SAFETY PLAN: Safety concerns are addressed through a number of programs, all of which center around employee training. Employees will be trained to anticipate where problems could occur and how to avoid them. A paramount tenet of this training is for employees to be clearly aware of surroundings before operating or moving any equipment. Additionally, equipment will be fitted with backup warning devices. Workers will wear required safety equipment in specified areas, including hard hats, safety glasses, dust masks, gloves, and steel -toed shoes. Workers will be trained to identify containers of potentially hazardous wastes. Such material will be removed from the wastes or recyclables and placed in specially marked metal bins located throughout the facility. Material collected in these bins will be removed by a hazardous waste company. Finally, signs will be posted throughout the site informing workers of safety procedures. • T'ne signs communicate both general safety procedures and procedures pertinent to specific pieces of equipment or areas of the facility. RELATIONSHIP TO OTHER FACILITIES: The Black River facility is an integral part of Rabanco's proposed mix of waste handling facilities for King County's CDL waste stream. All discrete (non -mixed) loads of concrete and asphalt, dirt and mud, and compostable wastes will be routed to the three facilities specifically designated for these wastes: Stoneway Concrete Recycling; a King County clean dirt disposal facility; and, the Cedar Grove Composting Facility, respectively. Mixed CDL waste will be routed to the Black River facility for separation. Separated compostables will be routed to the Cedar Grove facility for processing. Paper, cardboard, and scrap metals will be sent directly to markets. The remaining waste will be containerized at the Black River facility for transportation to Roosevelt. Seattle CDL: CDL generated within the City of Seattle will be directed to the Seattle CDL facility. The material will be handled at that facility in a manner similar to this one. Stoneway Concrete Recycling: Located across the street from this facility, Stoneway Concrete is an existing concrete and asphalt recycling operation. Rabanco will require the haulers of CDL to take loads of concrete and asphalt directly to the Stoneway facility for recycling. • • Cedar Grove Composting: As with Stoneway, Cedar Grove is an existing facility. At Cedar Grove, organic material is composted into usable soil material. Wood recovered from the CDL can be mixed in with the other organic material as a carbon -rich bulking agent. In addition, Rabanco will work with the haulers of CDL to encourage them to take loads of vegetative landclearing debris directly to Cedar Grove for composting. Auburn Train Loading (Proposed): A rail yard in Auburn may be used as a backup train loading area. • View Analysis Black River Waste Reduction Facility & Shipping Yard Affected Environment The site is a flat, wedge- shaped tract of land between 68th Avenue South and the mainline Burlington Northern Railroad. Three- fourths of the site is flat and recently graded. This area is about ten feet lower than the railroad tracks and forty feet lower than 68th Avenue South. The forested northwest portion of the site is more uneven, consisting of berms surrounding wet areas and a wooded hillside. In the northwest corner of the site is a pond with emergent wetland vegetation. Trees and shrubs also line portions of the boundary of the site along the railroad tracks. The graded portion of the site is mainly visible from the south and west. Because - of the site's low elevation with respect to its surroundings, most of it is not visible from Foster Golf Course to the west or Fort Dent Park to the south. However, it is visible from an office park to the southeast and from apartment buildings and other residences on the bluff rising from the Duwamish in Tukwila to the west and southwest. These views are often screened by off -site trees. In the views from the west, the site appears as a long strip of bare land between the railroad tracks and the gravel pit behind it. Alteration of Views by the Project Development on the site will include removing vegetation from part of the wooded northwest portion of the site, filling much of the site to the level of the adjacent railroad tracks, and constructing a large building near the center of the site. All of these actions will affect views that presently include the site. Because the building will have the most noticeable effect on views, the following analysis concentrates on its visibility. The proposed building will be visible from nearby sites across the railroad tracks and the Duwamish River. The lowest portion of views from 68th Avenue South will be partially obstructed. The building will also be visible from portions of Foster Golf Course, and from a short stretch of the Duwamish River. It may alter the view from those points, but it will not rise high enough to block the view of the gravel pit or the ridgeline above it. Sites immediately across the Duwamish River with views of the building are mostly commercial sites without significant public usage. These views are partially screened by trees. Potential views from Fort Dent Park to the south are completely screened by trees. Views from the office park to the south and from I-405 would not be substantially altered by the presence of the building. The closest residential view of the site is from a large apartment building in Tukwila on 64th Avenue South, about 0.5 miles from the site. No pictures were taken from this building Black River Waste Reduction Facility View Analysis 1 07/17/90 • • because potential views would be from the upper floors. However, the view would resemble that from Viewpoint A, which is about 0.2 miles farther up the bluff. Although the proposed building would be visible from this apartment building, it would not substantially alter the character of the view, which includes other large buildings. The building would be relatively low in the view and partially screened by trees. Photographs were taken at two more distant viewpoints farther up the bluff in Tukwila (see attached photographs), and an approximate outline of the building was sketched in to give a sense of its scale in the view. Photograph A was taken at Viewpoint A, near South 151st Street and 65th Avenue South. Photograph B was taken at Viewpoint B, near South 141st Street and 56th Avenue South. Although the proposed building would be visible from these viewpoints, it would not substantially alter the character of the view because of its relatively low elevation, partial screening by trees, and the presence of features of a similar or larger scale in the area. Mitigation Development on the site will be very visible from 68th Avenue South adjacent to the site, and possibly from portions of Foster Golf Course. A screen of trees along 68th Avenue South would hide most of the building in views from the roadway, but would also block views of the bluff on the other side of the Duwamish River. A screen of trees between the building and Foster Golf Course would significantly reduce impacts, but would require a few years to develop. The time before such a screen could be effective would be reduced if it could be planted off-site, on the golf course side of the railroad tracks.
