Permit L94-0049 - WSDOT - I-5 HOV / RIVER TRAIL SHORELINE SUBSTANTIAL DEVELOPMENT
<.. � L94 -0049 WA STATE DEPT. OF TRANSPORTATION SRS HOV /RIVER BIKE TRAIL SHORLINE The Fearey Group CFO Survey -- Page Two Recovery not until 2004 but improved profitability and market capitalization in 2003 While the results of The Fearey Group CFO Survey indicate that economic recovery for the Puget Sound region will happen later rather than sooner, the majority of CFOs were in agreement that profitability, revenue and market capitalization will be much improved in 2003. Inflation will be minimal, according to the CFOs. "The majority of CFOs see a stock market recovery at better than the historical rate of return based on how they see their equity growing," said Selby. • Sixty -one percent of the CFOs said the regional economy will recover in first half 2004 or later (39 percent said first half 2004 and 22 percent said later than that). Three percent said first half 2003 and 36 percent said second half 2003. • Nearly three - quarters of the CFOs said profits will increase in 2003. Fourteen percent said they would grow 1 percent to 5 percent, 20 percent said 6 percent to 10 percent and 37 percent said 11 percent or more. Conversely, 23 percent said profits would be flat and 6 percent said they would decline. • CFOs are even more optimistic about revenue growth for 2003, with nearly 90 percent saying revenue will grow. Twenty -nine percent said revenues will grow 1 percent to 5 percent, 26 percent said 6 percent to 10 percent, 32 percent 11 percent or more, but only 9 percent said they will be flat and just 3 percent said they will decline. • Almost two - thirds of CFOs (59 percent) said the value of their stock will increase 11 percent or more in 2003. Eighteen percent said it will increase 1 percent to 5 percent and 6 percent said 6 percent to 10 percent, while 18 percent said there will be no change. No CFO said the market capitalization of his or her company will decline. • According to the CFOs, inflation will not be a concern. Eighty -one percent said the rate of inflation for the region will be less than 3 percent, 19 percent said 3 percent to 4 percent and no CFO said it will be more than 4 percent. A brighter outlook for capital raising and capital expenditures? More than a third of CFOs said their companies will make significant capital expenditures in 2003 and nearly half believe that it will be less difficult to raise capital next year. Regional companies are also widely expected to be active on the merger and acquisition front in 2003, while gains in employment will be minimal. -- more -- Permit No: PW94-0174 Status: ISSUED Project: SP-5 HOV LANES Site Address: Location: #: Wetlands: Sewer: Contractor License No OWNER WSDOT FLO0 1 :ONE COTROL Issued: 01/05/1995 App..o,:al Letter: 01/03/1995 Expires: 07/04/199" IMMEDIATELV E OF 1340C INTERURBAN AV S.SP5 M.P.153.94-157.73 Wate?ccurse: .-Hopes: Water: UNKNOWN ENGINEER APPLICANT CONTACT Phone: i.206)440-4548 15700 DAYTON AVE N.,.SEATTLE,..

Sincerely, 4 Robert J. fritzen Shorelands Specialist Shorelands and Coastal Zone Management Program RF:rf RECREV.WP cc: Rick Beeler, City of Tukwila Memorandum TO: Jack Pace FROM: John Jimerson RE: Shoreline Permit Revision - WSDOT DATE: December 29, 1994 Project File No. L94 -0049 1. PROJECT DESCRIPTION: The Washington State Department of Transportation has requested a revision to Shoreline Permit No. L94 -0049 which was issued September 27, 1994. That permit allowed for adding an HOV lane to SR 5 and construction of a bicycle trail along the river. The site for the proposed revision is along East Marginal Way, just south of Interstate 5. The project includes replacing a damaged storm sewer outfall located on the west side of the Duwamish River with a new outfall with manhole. Rock rip rap will be placed from the outfall to the bottom of the river. Three trees (Scouler Willows) will be planted on each side of the outfall. 2. REVISIONS TO PERMITS: WAC 173 -14 -064 allows revisions to permits for projects which meet the following criteria: (a) No additional over water construction is involved except that pier, dock, or float construction may be increased by five hundred square feet or ten percent from the provisions of the original permit, whichever is less. Response: No over water construction is proposed. The new manhole and replacement outfall will be located upland of the ordinary high water mark. The new rip rap will be installed below OHWM. (b) Ground area coverage and height of each structure may be increased a maximum of ten percent from the provisions of the original permit. Response: This does not apply. The existing facility was not a part of the original permit. See (c) below for new structures. (c) Additional separate structures may not exceed a total of two hundred fifty square feet. Response: The manhole and outfall covers about 100 s.f. (d) The revised permit does not authorize development to exceed height, lot coverage, setback, or any other requirements of the applicable master program except as authorized under the original permit. Response: The proposal meets the development standards of the master program. See analysis below. (e) Additional landscaping is consistent with conditions (if any) attached to the original permit and with the applicable master program. Response: Landscaping condition has been attached. See analysis below. (f) The use authorized pursuant to the original permit is not changed. Response: The only change is an upgrade to the existing stormwater outfall. (g) No substantial adverse environmental impact will be caused by the project revision. Response: The project will not have substantial environmental impacts. 3.

Permit No: L94 -0049 14 SEPTEMBER 1994 COMMENTS / SUMMARY OF WSDOT LETTER DATED 1 SEPT. 1994 L94 -0049 Below I have summarized the salient points of the letter. Proposed Shoreline Management Conditions follow: 1. Trail. Public Works indicates that WSDOT verbally agreed to redesign the trail to increase the depth for footings. No documentation or design details have been provided to date. 2. In the WSDOT letter dated 1 September 1994, there are several comments related to the pending Final S &W Geotechnical Report. The final report is to include: a. whether revisions are necessary for the final retaining wall design; b. A further investigation will be conducted to investigate the Duwmaish River bank protection and river bank scour prior to finalizing the draft report. This investigation will occur late fall or winter. c. If the investigation reveals that bank reparation is necessary, WSDOT requests the City and WSDOT jointly apply to DOF for a hydraulics permit. d. If reparation is required, WSDOT assures work will be completed prior to expiration of 5 -year Shoreline Permit. e. To ensure riverbank stability for life of project, WSDOT proposes a slope monitoring program for the 800 foot reach as identified in the draft S &W report. Specifics of the monitoring program will be established after the report is finalized. Condition #1: No improvements can be made to the 800 ft reach as identified in the SW geotech report date... until June 1, 1995 (or specific agreed upon date) provided that the following occurs: a. A site investigation must be conducted of the Duwamish River Bank prior to December 31, 1994. b. The final geotechnical study must be provided subsequent . to the to the field investigation which addresses the need and extent of bank reparation. .,....�..`.,_.._._ ... b. The final geotechnical study must address bank monitoring if required. c. If final geotech. study indicates bank repair is required, completion must occur within five years from the date of the approved Shoreline Management Permit. d. If the final geotechnical study concludes that bank reparation is not required, the study must support this conclusion and why it differs from the conclusion in the draft study....

Because of the volume of plan trans- mittals, these plans have been sent to Brian Shelton for Phase 2, SR -5 HOV Lanes file in PW, rather than DCD's permit files. My only comment on the Shoreline Permit Application is that the conditions of this permit should refer to the April 1, 1995 deadline for submittal of the final plans for the bicycle trail and permanent riverbank protection as stated in the September 20, 1995 letter from WSDOT. Conditions to be included in the FCZ Permit are as follows: 1. This permit is conditioned on requirements and schedules identified in September 20, 1994 WSDOT letter (attached). 2. Riverbank stabilization will follow King County's Guidelines for Bank Stabilization Projects. 3. Conditions of the following permits from other departments and agencies will be followed at the time of issuance of permits: CORP's approval /permits; State Fish and Wildlife HPA; Department of Community Development approvals/ requirements; 4. Plans will meet final approval of City of Tukwila in accord- ance with the City's Flood Ordinance. 5. This permit will be issued for the same expiration date as the Shoreline Permit issued through DCD. This memo is my request to the ()evelopment Engineer to issue the FCZ Permit as conditioned a.►ove for the subject project. Finally, the requirements of Gary Schulz's September 15, 1994 memo are to be met by WSDOT. I assume this is DCD's charge to communicate this information to WSDOT as it is not a condition of the FCZ Permit process. Attachments (3) File: PF:prf:hov2 City of Tukwila John W.

WSDOT will prohibit work on this section of the project until July 1, 1995 to allow for completion and finalization of the Geotechnical Report by Shannon & Wilson (S &W) addressing the permanent Duwamish riverbank protection for "life of project ". Any revisions required to the design of the retaining wall footing elevations will be completed prior to July 1, 1995. Further investigation to complete the Geotechnical Report will be conducted late this fall or early winter when there is less vegetation along the river bank. The Geotechnical Report will be completed by December 31, 1994 jointly by S &W aliaNTSDerriiydraulics s. The final approved Geotechnical Report by S &W will recommend a bicycle trail design, wall design, riverbank protection and a riverbank monitoring program for the reach of the river within the project limits. The monitoring program will be administered by the WSDOT Geotechnical branch. Riverbank protection work recommended in the final approved Geotechnical Report will be scheduled for completion within 5 years of the Shoreline Permit to be issued by the City of Tukwila.

This landscaping project will immediately follow the construction of the SR5: Pierce County Line to Tukwila, HOV and Truck Climbing Lane project and the SR 5: Tukwila to Lucile, HOV project. We expect both of these projects to be complete in 1996. We expect the landscaping project to be completed in 1997. The Department of Transportation typically has separate contracts for the highway construction and roadside restoration to mitigate impacts during construction. This enables the work to be performed by a Landscape Contractor as the prime and allows for the longer period of plant establishment. It also enables us to respond to actual impacts created by construction. The funding for roadside restoration for this construction project is programmed. Areas in the median, as well as those in the roadside, which have been disturbed by construction will be restored following construction of the highway project. The design concept for vegetation restoration will create natural appearing groups appropriate to the scale of the facility and the design speed. Some areas will remain open to provide visual ?sue E9 reDviDe L1�1 , ALT 04401 )A contrast in the corridor. Highway design standards, including clear or recovery zone adjacent to highway shoulders, site distance, critical views of signals and signs, and consideration of illumination, drainage, utilities and maintenance needs will be incorporated into the revegetation design. Plant material will be trees and shrubs selected primarily from native species which are compatible with the highway corridor and the natural landscape. The selected plant species will be based on an evaluation of plants indigenous to the area such as Douglas fir, Western red cedar, big leaf maple, Oregon ash, vine maple, crabapple, and hazelnut. Initial plant spacing will be 8 to 10 feet to allow for natural selection of the species. A no irrigation concept will be used to accommodate water restriction policies. Soil amendments and mulch are used to improve moisture retention. Maximum survival and adaptability of plants is achieved using small installation sizes such as seedlings or up to 4- foot height for evergreen trees and up to 1 -inch caliper for deciduous trees. If you need additional information on our planting project please call me at 440 -4582 or our Landscape Architect, Sally Anderson at 440 -4501.

It is WSDOT's understanding that the City of Tukwila is requiring a Plan of Action from WSDOT to address the Duwamish river bank stability for the life of the project (20 to 30 years). This Plan of Action is required for the Shoreline Permit and the Flood Control Zone permit to be issued by the City of Tukwila. The Duwamish river bank stability and bank protection was discussed in the June 24, 1994 Draft Addendum No. 1 to the Phase 2 Geotechnical Report by Shannon & Wilson (S &W). A reconnaissance of the river bank was made on June 10, 1994, but access to the toe of the bank was limited due to extensive brush growth. This made it very difficult to visually inspect the area The'Geotechnical Report by S &W identified- soiiie..areas of . oversteepened bank and .a 100 foot section of unnprotect:ed- riverbank' Previously, in 1993, staff of the WSDOT Geotechnical Branch performed a field reconnaissance of this slope and found no areas exhibiting visual signs of instability. The Geotechnical Report by S &W has heightened WSDOT's awareness for potential de- stabilization of the existing armored slope along the left bank of the Duwamish. ' °The: report does not say`that'tliere is an imminent; danger for .failure `S &W's= report': includes` a' plan that would produce a longterm `stabilization'of the`bank;'however, placement of the rip rap would necessitate removal of mature existing slope vegetation at the toe of the slope along the river bank. Phil Fraser Department of Public Works City of Tukwila 09/01/94 Page 2 Enclosed is a August 26, 1994 letter from the Department of Fisheries outlining their concerns for any proposed riverbank protection work. Their letter makes note of the well established trees and vegetation and the importance of maintaining the vegetation along the riverbank. The DOF letter states that they would be reluctant to issue Hydraulic Permit Approval for bank protection because an area "might" erode in the future.

Should the results of this investigation and the final report conclude that bank repair needs to be performed for specific oversteepened or unprotected bank areas, - we propose that WSDOT and the. City of Tukwila jointly approach the Department of Fisheries.for the required Hydraulic Permit Approval. After Hydraulic Permit Approval is obtained, this work would be implemented by change order to the existing Tukwila to Lucile Street Stake 2 project or by a separate maintenance contract. This work will be scheduled for completion prior to expiration of the Shoreline Permit which we understand is 5 years from the date of issue: To address the riverbank stability over the life of project and beyond, WSDOT (1 proposes to implement a slope monitoring program for the 800 foot reach.of river- bank addressed in S &W's Geotechnical Report.

However, I did take photographs of the area. The following are some of the observations I made: 1. The banks were well vegetated with well established trees and shrubs (cottonwood, alder, blackberry). . 2. I observed some rip along the toe. It was difficult to tell if there was riprap under the sediments at toe. 3. I did not see any areas that were badly eroded or obviously damaged. As I said, the banks were well vegetated so I could not see if the upper areas were damaged. 4. The area is located in a straight reach of the river where erosion is less likely to occur. 5. Maintaining the large trees and shrubs is important to moderate temperatures, provide future wood debris input. In addition, this well developed riparian area provides excellent habitat for birds and small mammals. The Department of Fish and Wildlife will issue Hydraulic Approval for bank protection if there are damaged banks and the need to riprap is evident. We would be reluctant to issue approvals for bank protection because an area might erode in the future. Although mitigation for loss of habitat is required for bank protection projects (shrub planting, woody debris placement), it would take years for revegetated areas to provide the , 1 4 •H1_.2'.:O u4.ucIrri WLW ML',. -i 1 Don Wills August 26, 1994 Page 2 shading and temperature moderation that the large trees in this area provide. r.G I hope these comments are helpful and -I will gladly review any proposal for this area if they are submitted to us for review. - If you have any questions, please call me at 206-775-1311, ext. 107.

Wetland and Mitigation Plan The Department of Transportation is planning to construct an HOV lane and a truck climbing lane along southbound I -5 from the S. 188th interchange to Tukwila, the project limits are, MP 152.26 to MP 154.38. d. This project will be • constructed beginning in the summer of 1995 and scheduled to be completed within 24 months. Existing Conditions: There is only one impacted wetland within the project limits, the wetland is identified as the Klickitat wetland. The wetland lies adjacent to, and to the south of Klickitat Dr., it is west of Interstate 5. It has a total area of 19,324 SF (0.44 acres), of which WSDOT will impact 559 SF (0.01 acres). Wetlands Description: The particular area affected is a small forested and emergent wetland. Emergent wetland vegetation includes: reed canary grass, speedwell, velvet grass, scouring rush, soft rush and water parsley. The forested wetland area supports red alder and black cottonwood trees, with occasional western red cedar. Understory vegetation includes scouring rush, reed canary grass, and occasional Himalayan blackberry. , The site receives its hydrology from numerous outfalls and from groundwater seepage coining off the hillside. WSDOT biologists delineated the Klickitat wetland on March 15, 1994 and April 15, 1994 according to the 1987 Federal Manual for .Delineating Jurisdictional Wetlands. Project Impacts: All impacts to the Klickitat wetland occur as a result of widening the roadway for the HOV and truck climbing lanes. WSDOT has designed a wall (Wall 5) to help lessen the impact to the wetland. Due to the topographical restrictions and the necessity of adding lanes the impacts to the wetland are not avoidable. Because the expected permanent wetland losses anticipated are primarily within the emergent wetland area, the overall loss to wetlands functions and values is minimized. Conclusions: The required wetland mitigation ratio for replacement of expected losses within the Klickitat wetland is 2:1, wetland mitigation area to wetland loss area. WSDOT will be able to provide some mitigation at the Klickitat site through the construction of the retaining wall and grading that will occur in the area. The runoff from the hillside will naturally begin to pond behind the wall, the wall acting as a barrier will force the water to migrate to the south, to an area not currently a wetland. Over time this spreading will create a new (expanded) wetland. WSDOT will hand place the material for two rock check dams, this will assist in adding more water to the site thus enhancing the wetland creation process. WSDOT's mitigation plan for the Klickitat site is an upgrade enhancement from the current emergent wetland to a scrub /shrub environment. The plan sheet is included and shows the number and type of plantings to be done in the mitigation site. WSDOT's mitigation will provide 4,767.2 SF (0.1 acres) of enhanced wetland area, for a mitigation ratio of 8:1. WSDOT plans to mitigate for the Klickitat wetland impact within the same drainage basin and locale and additionally at a location near the Southcenter Parkway /SR 405/I -5 to SR 405 on -ramp (see enclosed plan sheet). The mitigation will occur in an area that is currently a wetland (97,975.1 SF, 2.25 acres), the mitigation will occur over an area of 4,767.2 SF (0.1 acre). Enhancement at this site will create scrub /shrub and forested vegetation within the existing wetland. WSDOT has also agreed to provide mitigation for the proposed instream wet ponds at the I -5 northbound off ramp to Southcenter Parkway. WSDOT will create a bioswale adjacent to the. ponds and parallel to the stream. Mitigation that we have committed to, includes the 4767.2 SF area along SR 405 and Southcenter Parkway and a strip between Southcenter Parkway and the I -5 northbound to SR -405 northbound ramp. WSDOT has provided the City of Tukwila with the landscape plan and we have included the planting'plan for the mitigation area with this document. It is the opinion of WSDOT's biologist that the wetlands affected by this project are isolated wetlands with total impacts less than 1 acre, and therefore a 404 Individual Permit should not be required. If it is determined for any reason that this is not the case and an individual permit is required, please notify us as soon as possible so we can begin the review process. Should you concur with our assessment please send a confirmation letter alerting us to your decision. Please contact Don Wills, WSDOT Environmental Coordinator, at (206) 440 -4522, should you need more information or have any questions. cc: D. Morimoto S.

It is WSDOTs understanding that the City of Tukwila is requiring a Plan of Action from WSDOT to address the Duwamish river bank stability for the life of the project (20 to 30 years). This Plan of' Action is required for the Shoreline Permit and the Flood Control Zone permit to be issued by the City of Tukwila. The Duwamish river bank stability and bank protection was discussed in the June 24, 1994 Draft Addendum No. 1 to the Phase 2 Geotechnical Report by Shannon & Wilson (S &W). A reconnaissance of the river bank was made on June 10, 1994, but access to the toe of the bank was limited due to extensive brush growth. This made it very difficult to visually inspect the area. The Geotechnical Report by S &W identified some areas of oversteepened bank and a 100 foot section ot'unprotected riverbank. Previously, in 1993, stab of the WSDOT Geotechnical Branch performed a field reconnaissance of this slope and found no areas exhibiting visual signs of instability. The Geotechnical Report by S &W has heightened WSDOT's awareness for potential de- stabilization of the existing armored slope along the left bank of the Duwamish. The report does not say that there is an imminent danger for failure. S &W's report includes a plan that would produce a long term stabilization of the bank, however., placement of the rip rap would necessitate removal of mature existing slope vegetation at the toe of the slope along the river bank.

Existing Wetland Conditions, City of Tukwila Wetlands within Stage 2 Project Area EXECUTIVE SUMMARY Washington State Department of Transportation is widening SR -5 to: 1) accommodate permanent inside HOV lanes in both northbound and southbound directions; 2) provide ramp metering, SC &DI systems, and ramp resurfacing; and 3) construct a bike trail adjacent to the Duwamish River's south bank. The project includes the portion of SR -5 located between the Tukwila Interchange at MP 153.94 and Lucile Street at MP 161.85. This Buffer Conceptual Mitigation Plan addresses sensitive areas impacts and compensation for Stage 2 of the project. Stage 2 extends from Interurban Avenue S at MP 155.98 to Boeing Access Road at MP 158.32, and will be constructed in 1995. No wetland impacts are anticipated. Approximately .25 acre of wetland buffer will be impacted by Stage 2 construction. Stage 2 area includes seven wetlands (Wetlands #4, #5, #6, #7, #8, #9, and #10), located in several drainage basins within the Duwamish River watershed. Wetlands # 5, #6, #7, #8, #9 and #10 are isolated wetlands located along the SR -5 corridor. Wetland #4 is located on the south bank of the Duwamish River in a location under and southeast of the SR -5 /Duwamish River bridge. Wetland #4 is within the 100 -year floodplain of the Duwamish River, a "Shoreline of the State" and is thus under the City of Tukwila's Shoreline Master Program jurisdiction. Wetlands #4, #5, #7, #9, and #10 are determined to be Type .2 wetlands according to the City of Tukwila Sensitive Areas Ordinance. Although relatively small and disturbed sites, all five Type 2 wetlands provide diverse and/or predominantly forested wetland classes of moderate to high value. Wetlands #6 and #8 are highly disturbed, Type 3 wetlands of low value. Required buffer width for Type 2 Wetlands #4, #5, #7, #9, and #10 is fifty (50) feet. A twenty -five (25) foot buffer is required for Type 3 Wetlands # 6 and #8. Wetland and wetland buffer losses are avoided by incorporating roadway alignments, widths and retaining wall designs that minimize sensitive area impacts. Stage 2 of the SR -5 HOV project avoids all wetland impacts. Unavoidable buffer loss at Wetla�ds #4, 6, and #7 buffers totals : 10,708 square feet (.25 acre). Construction of the bike trail along the south bank- of'the Duwamish River is not anticipated to impact the buffer at Wetland #4, but will run along the buffer edge for 50 feet or so. Widening for HOV lane construction will impact 1137 square feet (.026 acre) of Wetland #6 buffer, and 9571 square feet (.22 acre) of Wetland #7 buffer. Proposed buffer mitigation concepts have the goal of providing the required buffer widths around all wetlands within the project corridor. Buffer losses will be accommodated by: 1) designating and enhancing required buffer widths; and/or 2) providing additional buffer width area to compensate for buffer impacts and to allow for proposed buffer width averaging. Buffer mitigation concepts include: 1) _2) 3) 7285 square feet (.17 acre) of buffer enhancement at Wetland #4; 5320 square feet (.12 acre) of buffer restored or enhanced at Wetland #6; and 32,910 square feet (.76 acre) of buffer restored and enhanced at Wetland #7. Of the total .25 acre of buffer impacted, 84 percent or .21 acre is resto To mitigate for the 1704 square feet (.04 acre) of buffer area permanently lost to SR -5 construction, o er .8 cre will be enhanced. Buffer mitigation concepts emphasize preservation, restoration or enhancement of forested buffers. Where required buffer widths are not possible due to highway improvements, buffer width averaging is proposed. Buffer mitigation concepts are designed to be of higher quality and biological function than the existing buffers lost through highway construction that they are replacing.

Project Location Map SR 5 TUKWILA T ' LUCILE STREET HOV PROJECT Figure 1 1.0 INTRODUCTION This Buffer Conceptual Mitigation Plan addresses: 1) SR -5 High Occupancy Vehicle Lanes - Stage 2 construction impacts to existing wetlands and buffers within the City of Tukwila; 2) proposals for minimizing impacts; and 3) concepts for preserving, repairing, restoring, and enhancing sensitive areas and buffers as required by the City of Tukwila Sensitive Areas Ordinance No. 1599. Proposed mitigation concepts are intended to replace and improve existing biological functions and values of affected sensitive areas. Stage 2 of the SR -5 HOV Lanes project includes the portion of SR -5 from Interurban Avenue S to Boeing Access Road. Stage 2 construction is scheduled to begin in Spring 1995, and will include buffer mitigation. In preparing this Buffer Conceptual Mitigation Plan, the City of Tukwila Sensitive Areas Ordinance No. 1599 and Sensitive Areas Maps were reviewed and 60 percent complete construction drawings were analyzed for sensitive areas impacts as described herein. In addition, field verification of wetland delineations for Wetland #4, #6, #7 and #9 was performed during January through March 1994. All wetland delineations and verifications have been done according to the 1987 Federal Manual for Delineating Jurisdictional Wetlands. 1.1 Project Description Washington State Department of Transportation is widening SR -5 to accommodate permanent High Occupancy Vehicle (HOV) lanes between the Tukwila Interchange at MP 153.94 and Lucile Street at MP 161.85 (Contract No. OL- 0949). In addition the project will provide ramp metering, SC &DI systems, and ramp resurfacing. Stage 2 construction will include improvements to the existing SR -5 bridge overcrossing the Duwamish River. The State will also construct a portion of a bike trail within the City of Tukwila and along the south bank of the Duwamish River under the SR 5- Duwamish River bridge. A project location map is provided as Figure 1. Only those sensitive areas impacts due to Stage 2 construction are addressed in this mitigation plan. Stage 2 of the SR -5 HOV Lanes project includes the portion of SR -5 from Interurban Avenue S to Boeing Access Road. Stage 2 construction is scheduled to begin in Spring 1995, and will include sensitive areas mitigation. The SR -5 HOV Lanes - Stage 2 project area includes seven wetlands, located in several drainage basins within the Duwamish River watershed. In addition, Stage 2 includes a bridge overcrossing of the Duwamish River. Project staging and locations of wetlands are shown on Figure 2. 1.2 Existing Sensitive Areas Conditions and Project Impacts Seven wetlands (Wetlands #4, #5, #6, #7, #8, #9 and #10) are located within the Stage 2 project area described above. Wetlands #5, #6, #7, #8, #9 and #10 are isolated wetlands located along the SR -5 corridor. Wetlands #7, #8, #9 and #10 are likely remnants of an extensive wetland system existing in the area before urbanization. Wetland systems #9 and #10 and perhaps #7 are hydrologically connected by pipes under SR -5. Wetland #4 is located on the south bank of the Duwamish River in a location under and southeast of the SR- 5/Duwamish River bridge. Wetland #4 is within the 100 -year floodplain of the Duwamish River, a "Shoreline of the State ", and is thus under the jurisdiction of the City of Tukwila's Shoreline Master Program. Wetlands #4, #5, #7, #9, and #10 are determined to be Type 2 wetlands according to the City of Tukwila Sensitive Areas Ordinance. Although relatively small (each is less than 5 acres in size) and disturbed sites, all five Type 2 wetlands provide diverse and /or predominantly forested wetland classes of moderate to high value. Wetlands #6 and #8 are highly disturbed, Type 3 wetlands of low value. Required buffer width for Type 2 2 PARSONS BRINCIG:RHOFF OUADE & DOUGLAS, INC. REVISED BY GAYNOR LANDSCAPE ARCHITECTS/DESIGNERS, INC. Wetlands Location Map SR 5 TUKWILA TO LUCILE STREET HOV PROJECT Figure 2 Draft Buffer Conceptual Mitigation Plan SR -5 HOV Lanes - Stage 2 Washington State Department of Transportation 16 May 1994 Wetlands #4, #5, #7, #9 and #10 is fifty (50) feet. A twenty -five (25) foot buffer is required for Type 3 Wetlands #6 and #8. All seven wetlands along the Stage 2 area of the project corridor are within the Duwamish River watershed. Wetland #4 is in the Interurban Basin, Wetland #5 is in the Allentown Basin, Wetland #6 is in the 116th Street Basin, and Wetlands #7, #8, #9 and #10 are in the Norfolk Street Basin. Figure 3 shows general boundaries of the drainage basins. More detailed descriptions of each wetland follow. Included in the descriptions is classification of the wetland according to the City of Tukwila Sensitive Areas Ordinance and an assessment of each wetland's biological functions and values. See Appendix A for City of Tukwila Sensitive Areas Maps (portions). In general, wetland functions and values include: 1) wildlife habitat and biological support; 2) water quality treatment; 3) flood/stormwater storage and control; 4) groundwater recharge/exchange; 5) erosion control /shoreline protection; and 6) recreation, cultural significance and aesthetics. All wetland delineations and verifications have been done according to the 1987 Federal Manual for Delineating Jurisdictional Wetlands. See Appendix B, Biology/Wetland Report, Washington State Department of Transportation, September 1992, for additional information on wetland delineation methodology and existing conditions. Project impacts include both temporary and permanent wetland and buffer losses due to Stage 2 construction. Figures 4 through 9 show the delineated edge of each wetland and each wetland's anticipated project impacts including buffer impacts. A summary of existing wetland conditions and expected losses is found in Table 1. Wetland #4 Wetland #4 is a small, 3565 square feet (.08 acre), but diverse forested wetland Iocated on the south bank of the Duwamish River southeast of the SR- 5/Duwamish River bridge overcrossing. The wetland is disturbed and its buffer filled. Urbanization in the area yields evidence that this wetland may be a remnant of a larger riparian wetland system along the Duwamish River that has been filled over time. Forested wetland species found onsite include black cottonwood, Pacific willow, and Scouler willow. Scrub - shrub and emergent components of Wetland #4 include redtwig dogwood, salmonberry, reed canarygrass, and bittersweet nightshade. Hydrology is provided by the Duwamish River. Only' 250 square feet of the wetland is within the highway right -of -way. Over 50 percent of the buffer falls within the right -of -way. Although disturbed, Wetland #4 provides high value in all wetland function and value categories with the possible exception of aesthetics. Being more than 20 percent dominated by forest, Wetland #4 is classified as a Type 2 wetland with a required 50 -foot buffer. Wetland #4 is also within the 100 -year floodplain of the Duwamish River, a "Shoreline of the State ", and is thus associated with the shoreline and under the jurisdiction of the City of Tukwila's Shoreline Master Program. Wetland #4 is not shown on the City of Tukwila Sensitive Areas Maps. If it was mapped, Wetland #4 would be on Section 14/23/4. Bridge and bike trail construction will occur in the vicinity of Wetland #4 during Stage 2 of the project. Neither construction activity is anticipated to impact either the wetland or the buffer. However, bike trail fill 4 PARSONS BRINCKERHOFF WADE & DOUGLAS, INC. Drainage Basins SR 5 TUKWILA TO LUCILE STREET HOT PROJECT Figure "3' • Draft Buffer Conceptual Mitigation Plan SR -5 HOV Lanes - Stage 2 Washington State Department of Transportation 16 May 1994 will come up to the 50 -foot buffer edge for approximately 50 feet. Wetland #5 Wetland #5 is an isolated, 4288 square feet (.10 acre), linear and forested wetland located west of SR -5 along the base of a hill. The wetland extends from approximately STA 2652 +00 to STA 2656 +00 and is bordered to the west by the Burlington Northern Railroad tracks. The wetland forest includes black cottonwood, bigleaf maple, and red alder. The scrub -shrub component includes redtwig dogwood, snowberry, osoberry, and Himalayan blackberry. Skunk cabbage, horsetail, and yarrow comprise the wetland's emergent/herb layer. Hydrology is provided by groundwater seepage and runoff. Water has been observed to be ponded in this wetland in November and December. Only 1100 square feet of the wetland and approximately one -half of the east side buffer area is within the highway right -of -way. Due primarily to its forested component, Wetland #5 rates high in wildlife habitat and biological support. Because it is small and isolated, the wetland rates moderate to low in all other wetland functions. Because of the dominance of forested wetland, Wetland #5 is classified as a Type 2 wetland with a 50 -foot buffer. Wetland #5 is mapped as Tukwila Wetland 6 and is classified as a Type 3 wetland on the City's Sensitive Areas Map, Section 11/23/4. Its classification has been upgraded for this mitigation plan due to field observation of the forested wetland dominance onsite. Stage 2 construction will include HOV lane widening in both directions along SR -5. A retaining wall will be constructed on the west edge of the highway, including along the full length of Wetland #5. Due to the retaining wall, all wetland or buffer impacts are avoided for Wetland #5. Wetland #6 Wetland #6 is an isolated depression of 13,950 square feet (.32 acre) located east of SR -5 and south of the Boeing Access Road interchange, between STA 2711 +00 and STA 2713 +00. The wetland occurs within the existing Seattle City Light transmission line right -of -way and is underneath transmission lines. Wetland #6 is highly disturbed by previous highway and power line construction and ongoing maintenance. The wetland is dominated by emergent wetland species including reed canarygrass and cattail. Some forest species are beginning to grow on the periphery of this wetland and include black cottonwood, Oregon ash, red alder, and Pacific willow. Because this wetland is under power lines, these forested species will eventually be cut back or removed by utility maintenance crews. An intermittent stream and hillside springs provide the hydrology for Wetland 4t5. Only 700 square feet of the wetland and the western portion of the buffer are within the highway right -of -way. Because it is and will continue to be highly disturbed through utility corridor maintenance, small isolated Wetland #5 rates low in wildlife habitat, shoreline protection, and aesthetics. The wetland rates moderate to low in groundwater recharge, flood storage, and water quality treatment. Wetland #6, an emergent wetland, is classified as a Type 3 wetland with a required 25 -foot buffer. Wetland #6 is mapped as Tukwila Wetland 15 on the City's Sensitive Areas Map, Section 03/23/4. HOV Lane widening will expand the highway fill embankment to the east in the vicinity of Wetland #6. The 6 Draft Buffer Conceptual Mitigation Plan SR -5 HOV Lanes - Stage 2 Washington State Department of Transportation 16 May 1994 new fill slope will not impact Wetland #6 itself, but will impact approximately 1137 square feet (.026 acre) of the wetland's 25 -foot buffer. Wetland #7 Wetland #7 is actually a disturbed and fragmented system of four forested/scrub -shrub wetlands located west of SR -5 and south of the Boeing Access Road interchange. The wetlands extend from STA 2707 +00 to approximately STA 2726 +00. The Wetland #7 system appears to be a remnant of an extensive wetland system that existed in the area before urbanization and that possibly included the Wetland #9 and #10 systems to the north. Only Wetlands #7A, #7B, and #7C are shown on Figures 6 through 8. Wetland #7D is located to the west, well outside of the project's area of impact. Only the eastern wetland buffer appeals to be within the highway right -of -way. Wetland #7A is approximately 28,107 square feet (.65 acre) in size and extends along the edge of SR -900 from SR -5 STA 2707 +00 to STA 2710+50. Wetland #7B occurs due north of #7A from STA 2714+00 to approximately STA 2724 +00, and is over 1.5 acres in size. Wetland #7C is adjacent SR -5 between STA 2717 +00 and STA 2725 +50, and bordered to the west by Wetland #7B. Wetland #7C is the largest wetland in the system at 103,799 square feet (2.38 acres). Wetland #7D is over 1 acre in size and is located west of Wetland #7B. All four portions of the Wetland #7 system exhibit similar biological characteristics and wetland vegetation make -up. Each wetland is basically woody, consisting of a fringe of forested and scrub -shrub wetland classes, and has emergent wetland in the center. Forest species include black cottonwood, Oregon ash, red alder, Pacific willow, and Scouler willow. Redtwig dogwood and hardhack dominate the scrub -shrub class, and cattails, small - fruited bulrush, soft rush, bittersweet nightshade, and reed canarygrass comprise the emergent/herb layer. Runoff and possibly groundwater seepage appears to supply the hydrology for the Wetland #7 system. Due to the overall size of this wetland system (over 5 acres) and its woody, forested component, all individual wetlands in the Wetland #7 system rate high to moderate in all biological functions and values. Wetlands in this system are classified as Type 2 wetlands with 50 -foot buffers. Wetlands #7 are shown as Tukwila Wetland 2 on the City's Sensitive Areas Map, Section 03/23/4. Widening of SR -5 for HOV lanes and related ditch reconstruction will occur along Wetland #7C. Expanded highway fill embankments, including new ditch outfall at the south end of Wetland #7C, will not impact any wetland area but will impact approximately 9571 square feet (.22 acre) of Wetland #7Cs 50 -foot buffer. Wetland #8 Wetland #8 is a very small, approximately 4340 square feet (.09 acre), very disturbed, depressional emergent wetland. The wetland is located entirely within the highway's right -of -way fence, west of the southbound off - ramp from SR -5 to the Boeing Access Road. Dominant emergent vegetation is reed canarygrass. Wetland #8 serves as a catchment for surface water runoff, which provides the wetland's hydrology. Because of its small size, disturbed condition and lack of habitat diversity, Wetland #8 rates low in all biological functions and values. Wetland #8 is classified as a Type 3 wetland with a 25 -foot buffer. The 7 -, Draft Buffer Conceptual Mitigation Plan SR -5 HOV Lanes - Stage 2 Washington State Department of Transportation 16 May 1994 wetland is not mapped on the City of Tukwila's Sensitive Areas Maps, probably due to its location within the highway right -of -way. The southbound off -ramp will not be affected by Stage 2 construction. No wetland or buffer impacts are anticipated for Wetland #8. Wetland #9 The overall Wetland #9 system includes several wetland areas, all located west of SR -5 and north of the Boeing Access Road interchange. Only two portions of the overall Wetland #9 system are within the City of Tukwila. For the purpose of this mitigation plan, the two wetlands within the city limits are designated as one wetland called Wetland #9 Tukwila (#9T). Wetland #9T extends along the southbound exit ramp to the Boeing Access Road from SR -5 STA 2735 +50 to the Tukwila city limits. The eastern wetland edge is approximately 300 feet west of the ramp's centerline. Both wetland system and buffer are outside the highway right -of -way. Most of the wetlands within the Wetland #9 system are similar in biological and vegetative characteristics. These wetlands are highly disturbed and altered, and have edges well- defined by fill slopes from earlier highway, utility and railroad track construction. Similar to Wetland #7, the several wetlands in the 4t9 system are likely remnants of an extensive wetland system existing in the area before urbanization. Wetland #9's proximity to the Duwamish River may indicate that the wetland's hydrology has been or is influenced by the river's floodplain and groundwater level. In general, Wetland #9 system hydrology is created by intermittent streams, groundwater and runoff, in combination with impermeable underlying soils. The combined area of the two Wetland #9 Tukwila portions is 42,935 square feet (.99 acre). The vegetative make -up of Wetland #9T is similar to that of Wetland #7 and Wetland #9 South. Wetland classes include a woody forested/scrub -shrub edge with an emergent and/or open water center. Dominant forest species include black cottonwood, Oregon ash, red alder, Pacific willow, and Scouler willow. Redtwig dogwood, hardback, and Himalayan blackberry comprise the scrub -shrub layer. Cattails, rushes, and reed canarygrass dominate the emergent class. Wetland #9T's diversity of habitat, size of approximately one acre, and potential for flood/stormwater storage and water quality improvement rates this wetland as high in overall wetland functions and values. Wetland #9 in general is classified as a Type 2 wetland system with a 50 -foot buffer. Wetland #9 Tukwila is included in the larger Wetland #9, mapped as Tukwila Wetland 1 on the City's Sensitive Areas Map, Section 03/23/4. The southbound exit ramp to the Boeing Access Road will not be affected by Stage 2 construction. No impacts to either Wetland #9 Tukwila or its 50 -foot buffer are anticipated. Wetland #10 Wetland #10 is an emergent and scrub -shrub linear wetland, over two acres in size, and located east of SR -5 and north of the Boeing Access Road interchange. This wetland and its buffer occur entirely within the highway right -of way and extends from approximately STA 2734+00 northwards beyond the boundary of Stage 2. Wetland #10 includes a previously constructed wetland mitigation site that compensated for northbound HOV lane construction completed in 1990. 8 Draft Buffer Conceptual Mitigation Plan SR -5 HOV Lanes - Stage 2 Washington State Department of Transportation 16 May 1994 Dominant emergent vegetation includes small - fruited bulrush, soft rush, creeping buttercup, water parsley, and reed canarygrass. Redtwig dogwood, hardhack, Pacific willow, and Scouler willow comprise the scrub -shrub class. The mitigation wetland site is located at the southern end of Wetland #10 and has been moderately successful. Hydrology is provided by an intermittent stream and runoff. Wetland #10 is hydrologically connected to the Wetland #9 system by a culvert under SR -5, which is being improved and enlarged as part of Stage 1 of the project. Being greater than two acres and providing runoff storage and treatment, Wetland #10 rates moderate to high in stormwater control and water quality treatment functions. Because of the highly disturbed, physically narrow shape, and surrounding urban land uses (commercial /warehouse and highway), this wetland rates moderate to low in wildlife habitat and aesthetic functions. Primarily due to its size, Wetland #10 is classified as a Type 2 wetland with 50 -foot buffers. Wetland #10 is not mapped on the City of Tukwila Sensitive Areas Maps, probably due to its location within the highway right -of -way. Northbound HOV lane construction in this area was completed in 1990, thus no construction will occur along Wetland #10 during Stage 2. No impacts to wetland or wetland buffer are anticipated. 1.3 Wetland Mitigation Requirements and Summary of Existing Wetlands and Project Impacts The City of Tukwila's Sensitive Areas Ordinance requires a 11/2 :1 wetland replacement to wetland loss ratio, regardless of wetland classification. The SAO assigns specific buffer widths to wetland classifications. A 100 -foot buffer for Type 1 wetlands, a 50 -foot buffer for Type 2 wetlands, and a 25 -foot buffer for Type 3 wetlands are required. All wetlands within the SR -5 HOV Lanes - Stage 2 project are Type 2 wetlands, with the exception of Wetlands #6 and #8. A Type 2 wetland can be over one acre in size, less than one acre but with three or more wetland classes, less than one acre but with forested wetland over at least 20 percent of the area, the size of a heron rookery or raptor nest, and/or the site of native plant associations of infrequent occurrence. The wetlands along the Stage 2 corridor qualify as Type 2 wetlands due to either size, habitat diversity, and/or forested wetland class site coverage. No wetlands are impacted by Stage 2 construction. Wetland impacts are avoided through highway width variations and construction of a retaining wall along the length of Wetland #5. The combined total of wetland buffer impacts resulting from Stage 2 construction equals 10,708 square feet or .25 acre. A buffer impact of 1137 square feet (.026 acre) occurs on the west edge of the 25 -foot buffer for Wetland #6, a Type 3 wetland. A total of 9571 square feet (.22 acre) of 50 -foot buffer is impacted along the east side of Wetland #7C, a Type 2 wetland. These impacts result from highway fill slope extension and/or ditch and swale construction during Stage 2. Although no buffer impact is anticipated for Wetland #4, a Type 2 wetland along the Duwamish River, a bike trail will be constructed adjacent to the buffer for approximately 50 feet. Figures 4 through 9 are graphic presentations of existing wetland conditions and project impacts, if any. Table 1 summarizes existing wetlands, buffers and expected losses within the City of Tukwila, Stage 2 project area. 9 • w EXPECTED WETLAND OR BUFFER LOSS (square feet; acres) NO WETLAND OR BUFFER LOSS; BIKE TRAIL WILL RUN ADJACENT TO WETLAND BUFFER FOR 5d NO WETLAND OR BUFFER LOSS; RETAINING WALL AVOIDS IMPACTS NO WETLAND LOSS; 1137 SF (.026 AC) BUFFER LOSS l j NO WETLAND LOSS; 9571 SF (.22 AC) BUFFER LOSS ADJACENT WETLAND #7C NO WETLAND OR BUFFER LOSS NO WETLAND OR BUFFER LOSS NO WETLAND OR BUFFER LOSS 10,708 SF; .25 AC WETLAND FUNCTIONAL VALUE r DESCRIPTION HIGH VALUE;; FORESTED, RIPARIAN WETLAND ALONG DUWAMISH RIVER & UNDER SHORELINE JURISDICTION HIGH VALUE; ISOLATED FORESTED WETLAND LOW VALUE; ISOLATED EMERGENT WETLAND UNDER SCL TRANSMISSION LINES HIGH VALUE; LARGE, DIVERSE BUT FRAGMENTED, DISTURBED WETLAND SYSTEM LOW VALUE; SMALL, ISOLATED & HIGHLY DISTURBED WETLAND HIGH VALUE; PART OF LARGER, DIVERSE BUT FRAGMENTED, DISTURBED WETLAND SYSTEM MODERATE VALUE; HIGHLY DISTURBED, LINEAR WETLAND; HYDROLOGICALLY CONNECTED TO WETLAND #9 TOTAL AREA OF EXPECTED BUFFER LOSS (square feet; acres) U.S. FISH & WILDLIFE WETLAND CLASS(ES)» PFO DOMINANT; PSS & PEM PFO DOMINANT; PSS & PEM co) a S a PFO & PSS WITH PEM M PFO & PSS WITH PEM PEM & PSS SIZE OF WETLAND° (square feet; acres) 3565 SF; .08 AC [250 SF; .006 AC]r 4288 SF; .10 AC [1100 SF; .02 AC]r 13,950 SF; .32 AC [700 SF; .02 AC]r 5+ AC TOTAL; #7C - 2.38 AC [0 SF]r 4340 SF; .09 AC.

Although these goals and objectives are guidelines and criteria against which specific mitigation concepts are evaluated, actual mitigation plans for a project may not meet all of the goals and objectives due to site and project constraints. The target of this mitigation plan is to acheive these goals and objectives to the greatest extent possible. No site selection process was undertaken for this mitigation plan due to the ability to mitigate for buffer losses at each specific wetland site where impacts are anticipated. 2.1 Mitigation Plan Goals The following general goals guide this mitigation plan. 1) Provide for no net loss of wetlands values and functions 2) Mitigate for losses with additional, restored and/or enhanced wetland area that is equal to or greater than that required 3) Achieve mitigation within the same drainage basin where the loss occurs, if at all possible and practical 4) Provide for no net loss of stream functions within the project corridor and for no impact on stream functions upstream or downstream from the project due to proposed alterations and mitigations 5) Protect and enhance biological functions of existing wetlands and riparian corridors with the goal of improving overall values over the life of the project 6) Protect and maintain existing hydrology, including water quality, within existing and mitigated wetlands and streams 7) Revegetate or enhance wetlands, riparian corridors and required buffers with Pacific Northwest native plants, simulating similar native habitat communities in species composition, cover - abundance, and structure 8) Create naturalistic designs that optimize multiple functions including flood attenuation, water quality improvement, fish and wildlife habitat, aesthetic value, passive recreation and public education, as possible 2.2 Mitigation Plan Objectives The following objectives of this mitigation plan are intended to meet these above - stated goals. 1) Propose specific features (e.g. road alignment alternatives; retaining walls; naturalistic stormwater ponds) and/or construction techniques that minimize roadway impacts on existing wetlands and required buffers 2) Repair wetland areas, streambeds and buffers that are temporarily disturbed by construction through restoration of grades and revegetation with native species 3) Enlarge existing wetlands, if possible. Potential methods for enlarging existing wetlands include: 1) removing previously placed fills; 2) adding adjacent, connecting wetland area; and/or 3) reconnecting previously disturbed and fragmented wetlands 11 Draft Buffer Conceptual Mitigation Plan SR -5 HOV Lanes - Stage 2 Washington State Department of Transportation 16 May 1994 4) Ensure water quality protection and general habitat improvements for existing wetlands, stream corridors and buffers by revegetating with native plants that prevent erosion and increase diversity and multi - layered coverage, and by eradicating invasive and/or weedy non - native species 5) Emphasize restoration and/or enhancement of forested wetlands with inclusion of an understory of palustrine scrub -shrub and/or emergent wetland classes 6) Provide required buffer width for created, restored and/or enhanced wetlands, as possible; revegetate buffers with appropriate native plant community(ies) 7) Where required buffer width is not possible due to site constraints and/or highway improvements, provide additional revegetated buffer width and/or area to compensate for buffer impacts 8) Preserve and enhance upland habitat, including buffers, as much as possible 9) Design mitigation features (wetlands, riparian corridors and buffers) with special attention to aesthetic appearance and appeal, and to opportunities for improving existing biological functions and values In addition, mitigation concepts for this plan are evaluated against and pass the following tests: 1) Accomplish the required mitigation in both quantity and quality. Mitigation sites must have adequate size and hydrology. 2) Fit existing site conditions and constraints. Besides size and hydrology, mitigation sites must be accessible for mitigation construction anticipated, available for purchase or already in public ownership, and be in a disturbed condition. High quality habitats and/or sites of high environmental function are not desirable or suitable for mitigation. 3) Do the least harm and conversely, the most good In general, mitigation concepts are preferred that do not destroy one type of valuable habitat (e.g. forest) in order to create different habitat (e.g. wetland). Likewise, mitigation construction access or techniques that disturb valuable habitat or sensitive area are not desirable. Mitigation that occurs within the context of a larger ecosystem thereby enlarging or enhancing that system are encouraged. 4) Be economically and technologically feasible. Mitigation design should be straight- forward and simple, use "soft- tech" bio- engineering and incorporate affordable natural materials. The mitigation work should be constructable and biddable, use performance based specifications, and incorporate materials and techniques that are recognized in the local construction industry. 12 3.0 MITIGATION PLAN COMPONENTS The mitigation concepts compensating for buffer impacts from SR -5 HOV Lane - Stage 2 construction are developed at three locations: 1) Wetland #4 buffer, within the highway right -of -way; 2) Wetland #6 buffer, within the highway right -of -way; and 3) Wetland #7C buffer, within the highway right -of -way. Although no buffer may be impacted adjacent to Wetland #4, the proximity of fill slope and bike trail construction may indeed cause some minimal impacts to this high value, riparian wetland's buffer, which is also within the 200 -foot shoreline jurisdiction of the Duwamish River. Thus, revegetation and enhancement are proposed for the right -of -way area of Wetland #4's buffer. Stage 2 construction will avoid all wetland impacts through sensitive design of highway widening and inclusion of a retaining wall along Wetland #5. Specific features of the mitigation plan concepts are described herein and shown on Figures 10 through 12. Proposed buffer mitigation will consist of the following. 3.1 Buffer Mitigation Concepts 1) Wetland #4 Buffer Enhancement: Revegetate the buffer area within the highway right -of -way with native upland and facultative wetland tree species to enhance the area as a forested buffer. The area for buffer revegetation and enhancement is approximately 7285 square feet (.17 acre), and will be designed to improve biological function and value of the existing buffer. This work will compensate for any potential minimal impacts to Wetland #4 buffer due to Stage 2 bike trail construction. 2) Wetland #6 Buffer Restoration and Enhancement: Restore and enhance existing buffer and additional width area from the highway right -of -way edge to the proposed ditch. Restoration is proposed from approximately station 2711 +30 to station 2713 +10. Revegetation will be accomplished with native woody upland and facultative wetland shrub species. Shrub species will not exceed 12 feet in height due to overhead transmission lines. Area of buffer restoration and enhancement is approximately 5320 square feet (.12 acre). Of that area, 880 square feet is existing buffer restored and 4440 square feet is enhanced buffer and additional buffer width. This concept will mitigate for 1137 square feet of Wetland #6 buffer impact, including 257 square feet of permanent existing buffer lost to ditch construction. Additional buffer area will provide buffer widths to as much as 70 feet as compensation for a reduced buffer width of 20 feet adjacent the Stage 2 ditch. 3) Wetland #7C Buffer Restoration and Enhancement: Restore and enhance the buffer area within the highway right -of -way by planting native upland and facultative wetland tree and shrub species to re- establish the area as a forested buffer with shrub understory. Restoration is proposed from approximately station 2718 +50, the intersection of the proposed swale outfall with the existing 50- foot wetland buffer, to station 2726 +25. The area of buffer restoration and enhancement is approximately 32,910 square feet. (.76 acre), not including the proposed swale area. Of this area, 8124 square feet is existing buffer area restored, and 24,786 square feet is existing buffer area enhanced. 13 Draft Buffer Conceptual Mitigation Plan SR -5 HOV Lanes - Stage 2 Washington State Department of Transportation 16 May 1994 This concept will compensate for Wetland #7 buffer impacts totalling 9571 square feet (.22 acre), including 1447 square feet of permanent buffer lost to Stage 2 swale construction along Wetland #7C. All buffer mitigation will be designed with the intent to improve biological function and value of the existing disturbed buffer. Typical tree and shrub species for buffer revegetation may include the following native plants. Douglas fir western crabapple western serviceberry western hemlock western hawthorn thimbleberly western red cedar red elderberry oceanspray . Oregon ash western ninebark nootka rose �' feet (.21 acre) of the existing impacted buffer. The remaining 36,511 square feet (.84 acre) of proposed wetland buffer mitigation is enhancement of existing buffer areas or addition of new buffer areas in order to compensates for the 1704 square feet (.04 acre) of existing buffer permanently lost to Stage 2 construction. Buffer mitigation concepts emphasize preservation, restoration or enhancement of forested wetland buffers, with the exception of a woody shrub buffer at Wetland #6 due to the height restrictions of overhead transmission lines. At Wetland #6 where required buffer widths are not possible due to highway improvements, buffer width averaging is proposed. Buffer mitigation concepts are designed to be of higher quality and biological function than the existing buffers lost through highway construction that they are replacing. 3.3 Monitoring Mitigation monitoring is suggested for a minimum of 5 years and should be provided by qualified professionals experienced in wetland biology, ecology and mitigation. A qualified professional may be a wetlands biologist or an ecologist, botanist or landscape architect with wetlands experience. Monitoring shall determine . the successful buffer plant establishment and suggest remedial and/or maintenance actions to correct problems with successful plant establishment, and attainment of biological functions and values. 14 Draft Buffer Conceptual Mitigation Plan SR -5 HOV Lanes - Stage 2 Washington State Department of Transportation 16 May 1994 4.0 MITIGATION WORK PLAN 4.1 Schedule Construction of SR -5 HOV Lanes - Stage 2 is scheduled to begin in Spring 1995. Native plant revegetation of buffers, anticipated to be accomplished with primarily bare root and seedling stock, will be scheduled during the dormant season, approximately mid - November to mid - March, and when the soil is not frozen. 4.2 Revegetation Performance Standards Planting design will specify primarily seedling stock (liners or bare root) and will indicate oncenter spacings that provide adequate densities of plantings after an anticipated minimum 70 percent survival rate. Planting will occur in native onsite soils. No topsoil or fertilizers are specified for this work. Existing native soils may be amended with composted yard waste to a depth of 3 inches. Monitoring of plantings will continue for a minimum of 5 years and will identify replacement plantings, repairs, weeding and /or thinning needed to achieve the desired performance standards in habitat, succession and aesthetics. 4.3 Monitoring Plan Post - construction mitigation monitoring will continue for a minimum of 5 years. Qualified professionals, including wetlands biologists or ecologists, botanists and/or landscape architects with wetlands experience, should visit the mitigation sites in spring, summer and fall in each of the first 2 years, in spring and fall of the third year, and in spring for each year thereafter. Goals of monitoring shall include: 1) assessment of general buffer plant materials establishment; and 2) maintenance needs within buffer mitigation areas. Annual monitoring reports will be furnished to the Washington State Department of Transportation. At the State's option, a detailed statement of methodology for monitoring will be prepared in accordance with recommendations and requests of WSDOT and other interested agencies. 4.4 Maintenance /Contingency Plan The Landscape Contractor for the buffer mitigation landscaping shall maintain all plantings for a minimum of 3 years to a maximum of 5 years (to run concurrent with monitoring) after provisional acceptance of the work. The Contractor shall replant, repair, weed, mulch and thin revegetated areas as required to ensure a minimum 70 percent survival rate of native plantings to promote successful establishment of mitigation habitat and successional growth. Any erosion of graded areas, including but not limited to highway embankment fill slopes, ditches and swales, shall be repaired, reseeded, and restored by the General Contractor during the period of the prime contract. 4.5 Bonding The State shall require that the buffer mitigation work, revegetation and seeding be done by licensed and bonded professional contractors. An effort should be made to encourage contractors with experience in native plantings and habitat construction to bid on the project. 15 [ CHECKED BY F ENGR. .' DIST. ADM. 02/94 02/94 S. L.

LUCILE STREET - H.O.V. LANES MP 154.46 to MP 161.74 INTERSTATE 5 OL -0949 (Consultant Agreement Y -4819) Biology /Wetland Report by William S. Null Charles E. Plummer Biologists Washington State Department of Transportation. District 1 Environmental Section •SEPTEMBER, 1992 TUKWILA TO S. LUCILE STREET - H.O.V. LANES MP 154.46 to MP 161.74 INTERSTATE 5 Consultant Agreement Y -4819 Biology /Wetland Report (Supplemental Revision to the December, 1991 Report) PROPOSED PROJECT This report identifies the biological resources and possible impacts of constructing High Occupancy Vehicle (HOV) lanes along Interstate 5 (SR 5). The project will extend from SR 405/518, City of Tukwila in the south to Lucile Street, City of Seattle in the north. Both northbound and southbound traffic will receive this extra lane, which will constitute the innermost lane along the median. Widening for these lanes will be done in the median, wherever possible, and along the outside lane where necessary. Sections in Townships 23 N and 24 N of Range 4 E, W.M. constitute the geographic location of the project in King County, Washington. SETTING This project is within the metropolitan area of Seattle; the northern half traversing a steep slope which separates an industrial area to the west from a residential area to the east. Boeing Field (King County Airport) lies west of the project for most of this half. The southern half includes rolling hills with residential and commercial areas south of the Duwamish River. Soils in the project area consist primarily of the Bellingham and Puget series, although in . some instances they have been replaced by fill. VEGETATION The area has been highly disturbed and modified by human habitation. Vegetation consists of both native and planted 2 species, some of which are weedy and of little value like various grasses, Scotch broom (Cytisus scoparius), mullein (Verbascum thapsus), and Himalayan blackberry (Rubus discolor). Some wetland vegetation is present, and is found along the water courses and in low areas where subsurface flow exists. These wetlands are discussed in a separate section below. As of June, 1990, the Natural Heritage Data System, Washington Department of Natural Resources, had no record of endangered or threatened plants or ecosystems of state -wide significance in the vicinity of the proposed project (Swanson, 1990). WETLANDS Existing Conditions -- Wetlands are ecological systems transitional between upland and aquatic environments. Those found in this project include small remnants of once greater systems. As a result of disturbance and fragmentation, they possess much less value than that initially. In addition, most are isolated wetlands with little or no connection to significant systems. Utility forestry, right -of -way maintenance for highways and railroads, plus other human impacts continue to disturb these sites. This fragmentation and disturbance have left few remaining native vegetative communities or wildlife habitats. Storm water and other non -point pollution have decreased water quality as well. Using the U.S. Fish and Wildlife Service system (Cowardin et al., 1979), these wetlands are classified as palustrine forest, broad - leaved deciduous; scrub - shrub, broad - leaved deciduous; and emergent, persistent. Their hydrology extends from seasonally flooded through permanently saturated to seasonally saturated. Wetland Descriptions -- Wetland determinations were made by WSDOT Biologists using the Corps of Engineers Wetlands Delineation Manual (Huffman et al., 1987). If a nonjurisdictional wetland is impacted, e.g., drainage ditches, the usual mitigation is that of simply replacing the ditch. Should a jurisdictional wetland be impacted, compensatory mitigation will be expected. Furthermore, should such wetlands have particular importance because of location, habitat, and /or plant diversity, a recommendation of avoidance will be given because compensatory mitigation could not replace its role along the highway system. The wetlands encountered in this project are identified by number on the attached map (Figure 1), and are described below: Wog 1 1 3 Wetland 1 is located along a small stream between SR 405 and Southcenter Boulevard near the cinema. The vegetation consists of palustrine forest and scrub - shrub species with some emergent plants. Various roadways have broken the wetland into three sections, each of which support hydrophytic vegetation. Red alder (Alnus rubra), black cottonwood (Populus balsamifera), and Oregon ash (Fraxinus latifolia) make up the overstory while serviceberry (Amelancher alnifolia) and salmonberry (Rubus spectabilis) compose the shrub layer. The emergent vegetation is dominated by small- fruited bulrush (Scirpus microcarpus), soft rush (Juncus effusus), and cattail (Typha latifolia). Hydrology comes mostly from the stream, but springs and surface flow on some of the steeper banks also provide water. Recommendation: Avoid impacts to the greatest extent ' possible. This wetland is jurisdictional and of high value. Compensatory mitigation will be expected should an impact be made. Wetland 2 is a narrow strip on the east side of the northbound lanes, just north of the SR405/518 overpass at mile post (MP) 155. It consists primarily of a ditch at the toe of fill, and is dominated by reed canarygrass (Phalaris arundinacea) with some cattails. The approximate dimensions are 200 feet in length with an average width of 10 feet. Seepage from the above hillside and surface runoff provide the hydrology necessary to maintain this emergent wetland. Recommendation: This plant community 'is a nonjuris- dictional wetland created by the imperfect drainage ditch. If impacted by the highway construction • process, replacement of the ditch will be expected. Wetland 3 is about a mile further north but is situated on the west side of the southbound lanes, south of the SR 599 Interchange and north of the South 144th Street overpass. Like wetland 2, it is a palustrine emergent plant community dominated by reed canarygrass in a ditch at the toe of highway fill. This wetland is somewhat larger than that above, and extends well beyond the WSDOT right -of -way (R /W) to the northwest. • Recommendation: This plant community is a nonjuris- dictional wetland created by the drainage ditch. Should it be impacted by the highway construction process, replacement is all that will be expected. Wetland 4 is situated on the west bank of the Duwamish River just before it crosses under. SR 5 at Station 2645 +00. The wetland is east of the bridge, and is a d remnant of a larger area that has been filled in. Emergent vegetation near the river consists of reed canarygrass, and bittersweet nightshade (Solanum dulcamara). The forest and scrub -shrub vegetation include red -osier dogwood (Cornus stolonifera), black cottonwood, salmonberry, and Pacific and Scouler willows (Salix lasiandra and S. scouleriana). Hydrology is provided by the river. Recommendation: Avoid impacts to the greatest extent possible. This wetland is jurisdictional and of high value. Compensatory mitigation will be expected should an impact be made. Wetland 5 is north of the Duwamish River at the base of the hill, some 250 feet west of the centerline opposite Station 2655 +00. It lies just east of the railroad tracks, and has a narrow linear shape extending northwards some 1,000 feet (to at least a point approximating that of MP 157). The dominant overstory trees are red alder, bigleaf maple (Acer macrophyllum), and black cottonwood. Dominant shrubs include red - osier dogwood, snowberry (Symphoricarpos albus), Indian -plum or osoberry (Oemlaria cerasiformis), and Himalayan blackberry. Skunk cabbage (Lysichitum americanum), horsetail (Equisetum sp.), and yarrow (Achillea millefolium) make up the herb layer. Hydrology for this wetland comes from both upslope seepage and surface runoff. Water was ponded from mid - November through early December. Recommendation: Avoid impacts to the greatest extent possible. This wetland is of high value, and compensatory mitigation would be expected should an impact be made. Wetland 6 is situated east of SR 5, along the east side of SR 900 opposite Station 199 +00 (Station 2712 +00 of SR 5). The area is just south of the Boeing Access Road, and in a draw that is very disturbed, not only by the highways and various urban disturbances, but the power line corridor as well. Utility forestry tends to favor blackberries over the wetland forest that otherwise might form on portions of this site. An intermittent stream and downslope flow plus various hillside springs provide the necessary hydrology. • Vegetation consists of mostly reed canarygrass and cattail with some woody materials such as Pacific willow, black cottonwood, Oregon ash and red alder on the periphery. Recommendation: This plant community is a juris- dictional wetland, and if impacted by the highway I 5 construction process, compensatory mitigation will be expected. Wetland 7 is located on the west side of the south- bound lanes of SR 5 just south of the Boeing Access Road near MP 158. It extends southwards to just north of the northernmost Martin Luther King overpasses. The area has four wetlands which once were part of a larger system that has been broken up by fill for both railroad and highway. construction. The existing wetlands are basically woody with palustrine forest and scrub -shrub vegetation along the edges and emergent vegetation in the centers. Black cottonwood, red alder, Oregon ash, Pacific and Scouler willows, red - osier dogwood, and Douglas spiraea (Spiraea douglasii) make up the woody vegetation. The emergent vegetation consists of reed canarygrass, cattails, small- fruited bulrush, soft rush, and bittersweet nightshade. Hydrology is mostly from precipitation and surface runoff, but ground water seepage may also add to the supply. (This wetland corresponds to Wetland 2 of the City of Tukwila, 1992.) Recommendation: Avoid impacts to the greatest extent possible. This wetland is of high value, and compensatory mitigation would be expected should an impact be made. Wetland 8 corresponds to what initially was Wetland 4. . It is located west of the south -bound off ramp to Boeing Access Road, but just inside the DOT fence. Reed canarygrass is the dominant vegetation of this small (<0.1 acre) palustrine emergent wetland. The site is in a depression which serves as a catchment for surface runoff. Recommendation: This plant community is a juris- dictional wetland, and if impacted by the highway construction process, compensatory mitigation will be expected. Wetland 9 exists just north of the Boeing Access Road on the west side of SR 5. It consists of 3 wetlands that were broken up by fill and construction. This was probably an extensive system that has been filled in by highway, airport, and railroad construction. An apparent intermittent stream and impermeable Puget soils provide hydrology.. Vegetation along the banks consists of Pacific willow, Oregon ash, red -osier dogwood, Scouler willow, and Douglas spiraea. In the center areas emergent vegetation, consisting of cattail and reed canarygrass, is present. (This wetland corresponds to Wetlands 1 and 4 of the City of Tukwila, 1992.) 6 Recommendation: These wetlands are jurisdictional, and if impacted by the highway construction process, compensatory mitigation will be 'expected. Wetland 10 is located along an intermittent stream on the East side of SR 5 just north of the Boeing Access Road between Stations SB 2734 +00 and SB 1830 +00. (It is the wetland which Swanson (1990) reported on for the construction of an HOV Lane.) The southern portion of this wetland has been created as a mitigation site for an earlier project. This portion has been somewhat successful, but many of the plants along its banks have died. The sides of the original wetland along the intermittent stream have woody vegetation consisting of scrub -shrub plants including red -osier dogwood, Douglas spiraea, Scouler willow and Pacific willow. Emergent vegetation such as water parsley (Oenanthe sarmentosa), reed canarygrass, creeping buttercup (Ranunculus repens), soft rush, and small- fruited bulrush inhabit the lower portions. Recommendation: This plant community is a juris- dictional wetland, and if impacted by the highway construction process, compensatory mitigation will be expected. Wetland 11 is situated on the west side of the south- bound lanes at the toe of the highway fill just north of MP 159. It also lies east of the WSDOT Aeronautic Division's building at 8600 Perimeter Road. This wetland, although small in area, would be considered palustrine forested, broad - leaved deciduous because of its red alder and cottonwood overstory. Recommendation: Avoid impacts to the greatest extent possible. This wetland is of high value, and compensatory mitigation would be expected should an impact be made. Wetland 12 is the northernmost within the project, and is located at the toe of the slope along the west side of the southbound lanes. More precisely, it lies just south of the Military Road undercrossing (at MP 159.50) and behind or east of a large concrete warehouse building, extending south to a point opposite the • businesses of Wings Aloft and Flight Craft at, respectively, 8467 and 8285 Airport Way. It is a palustrine emergent, persistent wetland with cattails and reed canarygrass as the dominant vegetation along with speedwell (Veronica americana), small- fruited bullrush, horsetail (Equisetum sp.), and 'lesser duckweed (Lemna minor). Hydrology is supplied from seepage beneath the freeway.and surface runoff. The 7 shape of this wetland is linear; from three feet to 30 ft. wide by approximately 1,000 ft. long. Recommendation: This plant community is a juris- dictional wetland, and if impacted by the highway construction process, compensatory mitigation will be expected. Functional values -- These wetlands provide such functions as biofiltration of stormwater runoff, sediment retention, groundwater recharge, flow storage, wildlife habitat, and food chain support. Impacts -- Inasmuch as the widening must contend with such physical constraints as ramps, bridges, overpasses, underpasses, and reinforcement walls, the impact to wetlands is considered to be negligible if all work is performed within the state's right -of -way. If widening must occur beyond the right -of -way and thus, impact the wetlands, mitigation will be expected for no less than an equal amount of that taken. MITIGATION These wetlands are protected under Presidential Executive Order 11990, "Protection of Wetlands ", Governor's Executive Order EO 89 -10 and EO 90 -04, "Protection of Wetlands ", and WSDOT Directive 22 -27 and 31 -12 (HR). Each of these orders and directives require the use of all practicable measures to avoid wetland impact and to provide mitigation for unavoidable impacts. WILDLIFE Existing Conditions -- Swanson (1990), reported seeing song sparrows, a pair of mallard ducks and a common snipe near wetland 8. A covey of quail and a cottontail rabbit were flushed in wetland 8, and a dead rat was seen along the shoulder near wetland 12. These sites have only marginal wildlife values. However sites A, D, E and F have enough wetland forest and scrub shrub to make habitat for common birds such as song sparrows, vireos, warblers, and similar riparian species, as well as, butterflies. It is expected that only those species common to human disturbance and considerable noise can tolerate the available habitat remaining. Impacts -- No animal population is expected to be adversely affected by the project. 8 FISH Existing Conditions -- It is known that the Duwamish River, over which the project spans, has breeding populations of resident and migratory fish. Impacts -- Fish mortality may occur due to increased silt loads in streams during construction. Reducing wetland acreage adjacent to creeks and rivers can also alter flow patterns in streams, causing increased peak flows and reduced low flow levels. These impacts can be minimized by coordinating construction plans with interested tribes and also the Washington State Departments of Fisheries and Wildlife. REFERENCES City of Tukwila. 1992.

Box 330310 Seattle, WA 98133 -9710 RE: I -405 HOV Project - Draft Addendum No. 1 to Recommendations by Shannon & Wilson Dear David: John W. Rants, Mayor Ross A. Earnst, P. E., Director RECEIVED N,16 •.10 1994 DEVELOPMENT Phase 2 Geotechnical COMMU Report Design At our July 29, 1994 meeting you requested the City's concerns relating to the riverbank protection be stated in writing. In short, we're concerned the proposed trail is provided with permanent riverbank protection for "life of project ". The safety of trail users and associated liability to the City by the construction and operation of the public trail is a high priority. We recommend constructing the trail now as part of the I -5 HOV project. City can issue Flood Zone Control Permit to cover 1 -5 HOV work and also include the necessary permanent riverbank protection for the new trail once it is known. We understand that WSDOT will work with both State Fish and Wildlife and the City to develop a permanent riverbank protection plan. At our recent meetings, your geotechnical consultant, Shannon and Wilson, said the riverbank does not pose an imminent threat of danger. Our objective then is to write the FZCP in such a manner that allows us to determine the kind of a fix and when it will occur. We recognize that permanent riverbank protection needs further investigation in the fall of 1994 when foliage is minimal, allowing full observation of the riverbank. Furthermore, we anticipate that the riverbank protection solution can be determined by early 1995 and construction occur in 1995 -96. I look forward to receiving your plan of action to address the above. If you have any questions regarding this matter do not hesitate to call me or Brian Shelton at 433 -0179.

Edwards, Assistant Project Engineer for WSDOT, Gregory R. Fisher, Shannon & Wilson, Dan Goodin of Parsons Brinkerhoff and others from these three organizations to continue our discussion on application of the Shannon & Wilson riverbank stabilization study for I -5 HOV just N of Greenbaum's Furniture. Brian requested I brief you and Ross on the course of action WSDOT is taking resulting from this meeting, gain concurrence or redirection and get back to David by Monday morning (8/1). (Brian won't be back until 8/3).' WSDOT officials presented pictures from their archives of the riverbank from the time it was built to present. They also found an original riverbank section (1:5 to 1) to which the riverbank was constructed in the '60s. Some conclusions that were drawn at this meeting were: - The riverbank has receded, but only slightly (hard to tell because of new foliage) - The rip rap identified at 1 -1/2 to 1 slope is currently steeper :(0.5 to 1) in a few isolated areas - The first 100 feet of left bank north of Gre au m's Furniture Store bulkhead is unprotected. (no rip rap). - Current riverbank construction requirements. (King County's. Guidelines for Bank Stabilization Projects) are not met by the original construction [major issue:lack of keyed 'rip rap]. WSDOT officials stated they would rather monitor riverbank as recommended by their consultant, than provide permanent fix. At WSDOT's request, the City's concerns were voiced at this meeting, summarized as follows: �V 1. Safety for future trail users. Page 5 of Shannon & Wilson report states: "...the existing bank protection is inadequate for life of project (estimated to be at least 20 years)..." 2. Riverbank stability from (approx.) Station BT 31 +00 to Station BT 39 +00. Page 6 of Shannon & Wilson report states, "...Based on our understanding of the subsurface conditions, it appears that the toe of the slope is composed of clean sands that're very susceptible to erosion..." and, "In our opinion, the observed undermining and toe erosion which has occurred over the last 30 years will continue and Page 2 cause further oversteepening, if left unchecked We anticipate in the short -term, any failure of the slope as a result of further erosion would primarily be shallow and gradual in nature, resulting from progressive oversteepening of the slope. It is our opinion that it is unlikely that a single storm event would cause a rapid retreat of the bank to the bike trail. In the long -term this progressive oversteepening could result in a large slide or set -down of the slope, possibly affecting the proposed bike trail." 3. Transferred liability to City via permitting (FZCP and 1 Shoreline), and future trail maintenance. 4. High potential for liquefaction of soils under seismic conditions (S & W voiced this concern at meeting, but indicated that this is concern in many areas of this state). David Edwards requested that these concerns be sent to WSDOT in writing. Brian requested Phil to draft the letter. Also stated at this meeting were the following: A. DCD has stated the City's shoreline permit will be tied to the City's FZC (Flood Zone Control) permit. B. Public Works Director recommends building the trail now and extend /condition the Shoreline and FZC permits to allow riverbank stabilization work to be completed at later time in HOV project or separate project. lioQ. ZG b If an extension of time is allowed it needs to be tied into a specified timeline for completion of all work. Turn over of trail maintenance will not occur until riverbank fix occurs to assure safety to trail users & limited liability to City. C. Dan Goodin of Parsons Brinkenholf recommended the foundations for trail wall(s) be lowered and walls extended so walls will be out of zone of influence of potential riverbank failure. D. Phil Fraser suggested further investigation by S & W to provide riverbank at critical segments, along with recommendations for both monitoring and maintenance might provide a modified "life of project" recommendations from S & W. S & W represen•.atives said this would require added investigation in the fall months when the foliage was gone. Dan Goodin said use of a boat might be needed to fully investigate the condition of the riverbank. qE Brian Shelton suggested that State Fish & Wildlife field review with WSDOT and City, the types of riverbank fixes we were now considering to assure they were in agreement. Page 3 From this meeting WSDOT requested the City's concerns be put in writing. WSDOT will then respond to the City's concerns by letter. WSDOT's designers need to implement the trail wall foundation lowering and extension of the trail wall now to stay on schedule. A field meeting will be scheduled with State Fish and Wildlife to assure they are in agreement with the direction of any riverbank fixes. We anticipated that S & W will carry out further investigations and recommendations rega di=ng 1) Depth and extensi -n of trail wall; 2) Extent ofdiate riverbank fixes; recommended monitoring and on -go g_m tenance program to assure life of project solution. Finally, WSDOT will develop a Trail Maintenance Agreement for the City's review in the near future. cc.

DEVELOPMENT Notes from meeting this morning with WSDOT, WSDOF, PBQ &D, Shannon & Wilson, Phil, and me to discuss bank slope stability problems north of Greenbaums furniture store. Shannon & Wilson provided a draft geotech report for the two walls necessary to provide trail section along the river near Greenbaums. The report includes a bank stability evaluation. The report noted a timber bulkhead along Greenbaums frontage, no slope protection for the next 100 feet north, and riprap protection with evidence of oversteepened bank for the next 500 feet + / -. The oversteepened bank sections vary in slope from 0.5:1 to 1.67:1. The 1964 WSDOT design plans for this segment show riprap at 1.5:1 slope on the bank without being keyed . at the toe of slope. In•the geotech's opinion, there is a low risk of instability of the SR5 roadway embankment in this area based on current conditions. However, the existing bank protection is inadequate for the life of the project(at least 20 years). The geotech recommends 1) immediate stabilization of the unprotected 100 feet of bank, 2) long -term bank stabilization using riprap on a 2:1 slope, 3) slope monitoring if 1 & 2 are delayed. Preliminary options appear to be: 1. rebuild bank at 2:1 slope w /riprap in phase 2, 2. rebuild bank at 2:1 slope w /riprap in phase 3, 3. rebuild bank at 2:1 slope w /riprap by Maint.contract 4. implement bank /slope monitoring program WSDOT seems to be opting for monitoring right now because of potential time delays with respect to permitting and possibly cost which could lead to delaying the project ad and jeopardizing getting the project built. The project ad is scheduled for September, 1994. PBQ &D is doing cost estimate for long -term bank stabilization. WSDOF would like more proof of need to do something since the "problem" is so long -term in developing. However, is willing to work toward acceptable solution. Phil commented that indefinitely delaying the fix would not be prudent since the soils report indicates loose soils down to 30 feet, existing riprap is not keyed at toe of slope, other failed structures nearby (upstream at WSDOT outfall and Greenbaums timber bulkhead), and a new public facility being provided closer to the river. The only decision reached was to schedule next meeting for: July 29, 1994 8:30 am WSDOT office (Dayton Ave.) This will allow design group to do cost estimate and get comments from HQ soils and everybody to give more thought to . geotech report and consequences. cc: Phil F. Denni Shefrin Gary Schulz Don Williams file: 91-RW14-1 7 MEMORANDUM RECF= I\A"--": JUL 0 11994 TO: Brian Shelton, Senior Engineer Denni Shefrin, Associate Planner FROM: Gary Schulz, Urban Environmentalist DATE: 6/30/94 RE: (..Vlvtivs1—JIv1 1 r DEVELOPMENT Design Recommendations for Retaining Walls NW -1 & RW -1, WSDOT HOV North. I have reviewed the Shannon & Wilson report and looked at the site this afternoon. I have a few comments regarding the recommended bank stabilization. 1) From what I could see through all the blackberries, the slope is oversteepened for most of this area. Also it appears that the slope toe could be undercut in many places. However, I did not see any recent, severe slope failure. 2) Most of the bank along this stretch has been rip- rapped and is heavily vegetated. There are many healthy trees that are apparently providing support to the bank throughout most of the area that the S & W report recommends a revetment treatment. If I understand the report and purpose of your meeting, it appears there is a consideration for adding rip -rap to the bank toe throughout the subject river segment. This undoubtedly is going to be a very costly endeavor. Existing native vegetation will likely be impacted by the work. I would have to recommend a bio- engineering approach to those areas that are really in need of repair for the bike trail stability. Any additional rip -rap installed along the toe will narrow the channel and reduce capacity unless the entire river bank is re- built. Whatever the measures needed, there should be a fairly intensive evaluation of the S & W recommendation to revet the entire bank segment if this means that all of the bank will be altered.

There is no questions WSDOT intends to address the Shoreline Permit. At the 2 WSDOT meetings I've attended the timing and link of the Shoreline Permit were tied to the FZCP. WSDOT officials brought up the Shoreline Permit at these meetings. WSDOT has always been aware of the Shoreline Permit required by the City but not the FZC permit. Early this week I called WSDOT officials and reminded them of the Shoreline Permit for two conditions: Short term Riverbank (1 - 2 years) protection and Long term riverbank protection for "life of project fix" (maximum of 5 years after the Shoreline Permit issued). WSDOT agreed to tie the Shoreline. Permit in both phases in their plan of action letter.

Box 330310 Seattle, WA 98133 -9710 (206) 440 -4000 Over the past few months the Washington State Department of Transportation (WSDOT) has been soliciting input from you and your neighbors regarding proposed plans to construct two noise walls in your Tukwila neighborhood. The first noise wall proposed is along the Interurban Interchange northbound on -ramp. This 1,400 foot long noise wall would begin on the embankment and run along the river to the ramp bridge. The second noise wall is proposed for the east side of northbound I -5 beginning just south of 144th Street in Tukwila to just north of 51st Ave South. Tukwila residents who attended the community meeting held June 9th at the Tukwila Community Center voiced overwhelming support for construction of these two noise walls. Many residents also asked the WSDOT to consider extending the noise wall proposed for 144th Street area even further north. Based on the input gathered at the recent community, meeting the WSDOT will construct both noise walls proposed for Tukwila neighborhoods. The noise wall along the Interurban on -ramp will be constructed as proposed. In response to community requests, the noise wall proposed along S. 144th Street will be extended an additional 400 feet to the north and will end approximately 60 feet north of S. 138th Street. Noise wall construction will take place between 1995 and 1997 and coincide with the construction of high - occupancy vehicle (HOV) lanes on I -5 between Tukwila and Lucile Street in Seattle. On behalf of the WSDOT, I thank you for your participation in this decision - making process. If you have any questions regarding this decision, please call me at 440 -4581. Sincerely, David L.

Because a portion of the pond /swale facility lies outside of WSDOT right - of -way and in the public right -of -way of Southcenter Parkway, the City will issue a street use permit for its construction, operation and maintenance. This permit will be issued upon approval of your final construction plan. If you have any questions regarding this matter, do not 'hesitate to call me at 433 -0179. Sincerely, 1� \ Ron Cameron, P.E.

To enhance safety and traffic flow, two new HOV connections at interchanges will be constructed and one substandard on -ramp will ' be closed. New discipline studies on noise, air, and wetlands have been prepared for this reevaluation. Impacts and mitigations have been addressed to meet current environmental requirements. DESCRIPTION OF CHANGED CONDITIONS I. SR 5, Tukwila to Mercer Street Transit /Carpool Improvements has been divided into the following projects. Tukwila to Lucile Street has been incorporated into Tukwila to Lucile Stages 1, 2 & 3. Tukwila to Boeing Access has been incorporated into Tukwila to Lucile Stages 2 & 3. Albro to East Roanoke has been, incorporated into Albro to Ship Canal. SR 5 SR 5• SR 5 SR 5 SR 5 Mercer to Yesler - SB HOV (Completed) Lucile to Jefferson HOV Lanes (Under Construction) Boeing Access to Lucile - NB HOV Lane (Open to Traffic) Tukwila to Lucile Stage 1 (SB HOV from Lucile to Boeing Access Rd.) - HOV.Lane, SC & DI, Ramp Meter & HOV By -pass. (In development, Ad date Feb. 1994) Tukwila to Lucile Stage 2 (NB & SB from Boeing Access Rd. to SR 599) - HOV Lane, SC & DI, Ramp Meter & HOV By -pass. (Not started, Ad date Sept. 1994) 1 SR 5 Tukwila to Lucile Stage 3 (NB & SB from SR' 599 to Tukwila) - HOV lane SC & DI, Ramp Meter & HOV By- pass. (Not started, Ad date Jan. 1995) SR 5 Albro to Ship Canal - Ramp Meter & HOV Bypass (In development, Ad date July 7, 1993) 2. Ramp meters with HOV bypass lanes are proposed at the following locations: ■ SR -518 to I -5 northbound ■ Southcenter Boulevard to I -5 northbound ■ SR- 599 /east and west ramps to I -5 southbound ■ Interurban Avenue to I -5 northbound ■ SR -900 northbound to I -5 northbound ■ SR -900 southbound to I -5 southbound ■ Boeing Access Road to I -5 northbound ■ Swift Avenue S. to I -5 northbound ■ Michigan Street /Swift Avenue S. to I -5 southbound A•section of the Duwamish River Bike Trail, where .1-5 crosses the river near Interurban Avenue, will be constructed in this project. 3. Two new HOV connectors at 1 -5 /I -405 interchange and I -5 /SR 599 interchange. Southbound Connector The Southbound HOV connector will begin just south of the Duwamish River Bridge and continue through the SR -599 interchange on a new roadway to be constructed in the I -5 median. This new roadway will connect back into the existing HOV lane just south of SR -599. Further south, the HOV lane again splits off onto its own separate roadway through the 1 -5 /I -405 interchange and connects south of the interchange with the existing HOV lane. Northbound Connector The northbound HOV connector will separate from the general purpose lanes just north of the Klickitat overpass. This new HOV lane will continue northbound, parallel to the new southbound HOV lane, through the median of the interchange, and begin running adjacent to the northbound general purpose lane to the Duwamish Bridge. 4. Due to the geometric and traffic revisions on the E -S Collector (Michigan to I -5) Ramp, the substandard Graham Street /South Congiat Drive to 1 -5 southbound ramp will be closed. The slip ramp does not have legal access according to the current right of way plans. 2 • HAVE ANY NEW OR REVISED LAWS OR REGULATIONS BEEN ISSUED SINCE APPROVAL OF THE LAST ENVIRONMENTAL DOCUMENT THAT AFFECT THIS .PROJECT? YES (x) NO ( ) (If yes explain, use additional sheets if necessary) Yes, the Clean Air Act Amendments of 1990 and the Corps of Engineers revised 1992 Nationwide Permit regulations were issued since approval fo the last environmental document.

WSDOT examined 69 potential sites for adding noise protections. As a result of that study the following four locations meet the criteria for noise barriers: ■ The South 144th Street neighborhood ■ The 56th Avenue South neighborhood ■ The Van Asseit neighborhood ▪ 240 foot extension to the south portion of the existing Pearl Street barrier 2. WSDOT biologist has identified twelve wetlands within the I -5 corridor. The new HOV lanes have been developed so that there will be no infringement cn wetlands in the project corridor.. 3. To comply with the Federal Clean Air Act'Amendments of 1990, the WSDOT has prepared an air cuality report. The NAAQS (National Ambient Air Quality Standards) for carbon monoxide are 9.0 parts per million (ppm) for 8 hour hourly average and 13 to:a for a 1 hour. The study indicates that neither the build nor the no build alternative will produce a NAAQS violation. CONCLUSIONS and cr RECOMMENDATIONS There have been no significant changes in the proposed action. Conclusions reached with regard to the anticipated impacts of the selected alternatives were not chanced by the additional analyses conducted since the publication of the Document. Mitigation measures have been incorporated into the project, but they do not . require significant changes in the project. As a result of the foregoing, it is the conclusion of this consultation that the Document continues to be valid. It is not deemed necessary to suotlement it prier to proceeding with major apt-ovals or authorizations. 4 • I concur with the conclusions and recommendations above Dist. /Division Official ►sGti(.t. yi Date:/2v47/4 • cc: FHWA Regional Office WSDOT HQ Offici -1 FHWA Official Date: ate: SHORELINE SUBSTA 1TIAL DEVELOPMENT REcEivEAPPLICATION CITY OF TUKWILA JUN 2 81994 DEPARTMENT OF COMMUNITY DEVELOPMENT, M M U N ITY DEVELOPMENT 6300 Southcenter Boulevard, Tukwila, WA 98188 Telephone: (206) 431 -3680 FOR'S,TAF uSE� ONLY 1.

This document is an addendum to out Phase 2 Ge technical Repptt for Bridges, Retaining Walls, and Major Earthwork Areas, dated Tune 1994. The two wails are listed below: 1. NW-1: Station , BT 28 +98 IX to , 2641 +87 BT 2. RW-2_ Station $ ET 29 +25 to 38 +75 BT The purpose of this study was to evaluate the subsurface conditions along the proposed alignment of the walls, and to address specific concerns associated with river bank erosion and slope stability. 2.0 P t,QPOSED M part of the SR-5 HOV lane improvements, a bike ail will be calm:nutted along the 1eit bank of the Duwamish River, under the south end of Bridges 5/526 E and W, along SR -5 to Interurban Avenue. In this area of the project, the river males sevraal shalt beads, most noticeably a tight, U- shaped bend at the south end of the proposed Was trait (see Figure 1). A major portion of the trail will be constructed at grade or with only minor grading. We retaining walls will be required, however, as the extension moves ftumn the edge of the river and cuts across the roadway embatt to Interurban Avenue (Figure 1). The uptiope wall (NW-1) will be about 1,280 feet long and will have a design height ranging from 5 to 14 feet. We understand that this wall will be a nonstandard, concrete, =Hever retaining wall with an integrated traffic barrier and noise barrier wall. The downs1ope wall (RW 2) will be about 950 feet long, and will have a design height of 7 to 8 feet.

The appmximate Location of these bearings are shown on Figure 1. Too generalised cross- sections showing the approximate location of the was with. =Pot to existing topographic f atuaes are presented on Figures 2 and 3. Subsurface conditions along the walls ate graphically depicted an the Ge nmaliaod Substage Nagle, Figure 4. In general. the borings encountered 5 to 38 feet of tall, down to *mica 6 to 10 feet (City of Seattle datum). The fill consisted of very loose to medium dense, salty, gravelly SAND, sandy SILT, and sandy GRAVEL. Gravel -sired sandstone fragments wens encountered at the bottom of the fill layer in boring BR-6. Cobbles vice inferred from drilling action near the bottom of the fill layer in boring BN -10. The fill was generally underlain by about 15 feet of loose to medium dense silty, fine SAND and fine sandy ITT (down to elevation -6 to -10 feet). South of about Station $ Er 36 +00, the SAND /SILT sequence a included a 5- to 7-fret-thick Layer of soft to medium stiff, slightly clayey to clayey SILT (from elevation +2 to -5 feet). The SAND /SILT was underlain by loose to dense (generally medium, dense), clean to slightly silty, fine to medium SAM) in all of the borings except baring BB-21. In this baring, the fill and SAND /SILT were undedain by medium dense (grading to vary dense), silty, fine SAND and fine sandy SIT to about elevation -45 fleet. This layer was underlain, in order of increasing depth, by medium stiff CLAY (from elan -45 to -57 feet), medium dense to very dense SAND (to elevation -104 tea), and very stiff CLAY to the bottom of the boring (elevation -108 feet). No observation wells nerd installed in the currant borings upon completion of drilling. Du=ng drilling, groundwater was measured at elevations of about 16 fleet, 6 feet, and -3 feat in borings BR-11, BN-9, and EN -10, respectively. No groundwater was encountered in the other borings during drilling, although a majority of these borings were completed using mud rotary techniques, which does not allow observation of a groundwater level. Mk anticipate that the groundwater level in this area would be influenced by and to be near the elevation of the Duwamish River.

Design drawings showing the placem it of heavy -loose L jn p alcmg the left bank of the aver in 1964 (Reference 1). 2. Cris- sections based on recent survey by David Evans and Associates (DEA). 3. Federal Emergency Management Agency (FEMA) 1980 data showing a cross- section in the vicinity. Each of these documents is discussed below. The 1964 design plan indicates that heavy -loose riprap was to be placed along the left bank of the river tom about Station $ wr 32 +30 to 38 +00 during original freeway construction. The ripzap was to be placed to elevation 12 feet on a 1.513:1V slope. No bottom demon of the rock was indicated; however, the drawing suggests that the riprap was placed on the river bottom and not embedded. The recent cross - sections based on survey by DEA indicate a river bank slope of 0.9/1:1V (horizontal to venial)) from Station BT 32 +40 to 33 +20, 1.67111V from 33 +20 to 34 +60, 1.25IV from 34 +60 to 35 +60, and 0.5H:1V from 35 +60 to 37 +10. North of % Br 37 +10 and south of 32 +40, the recent cross sections indicate a slope of 1.5H:1V or flatter: An attempt v.es made to compare the 1980 FEMA cross - section with the recent moss- sections by DEA in order to determine the rate of erosion in the last 14 years. However, it • vas not possible to precisely locate the FEMA caws- section because it lacked a detailed description and did not correlate well with the existing topography and S1L•5 r+oadeay elevation. Making some assumptions regarding the ]location and elevation of the 1980 moss- section, we concluded that it was taken near Static 1� ST 35 +50. Comparing the 1980 FEMA cross- section to the went one completed by DFA shows that the river bottom elevation in 1980 is similar to that in the recent survey, about elevation -12 feet. A comparison of the bank slope, hoacver, indicates that the slope is flatter today then in 1980, suggesting a possible ezror in the 1980 cross - section (in this azea the slope changes W- 5973-97 3 • +3063825222 PARSONS BRIFICKERHOFF F-987 T-939 P-005 JUN 21 '94 1304 SHANNON &WILSON.

However, beams the 1980 cross-section cannot be directly compared to the recent survey, it is our opinion that it should not be relied upon in an evaluation of riverbank procemes over the last 14 years. 4.2 Siraceonnassence A site visit was made by representatives from our firm on June 10, 1994 to observe the wig bank of the river along the area of interest. Our observations are summarized below. • Near the south end of the proposed walls at Station /I. sr 31+00 (behind Greenbaums Furniture Store), the left bank of the Duwambh River is confined by a timber bulkhead. From our discussions with reposeatativcs of Grearbaums, understand that this %van has recently been repaired. Further north (approcimately Station 1, Br 32+00), the left bank is confined by the fill embankment placed far the construction of the 5/526 E and W bridges. The first 100 feet of the left bank *mid the bulkhead is =protected; beyond this area the river bank is mewed by limp. The approximate eatait of ripmp protection and its size (i.e., large size rock similar to heavy-loose ripmp) is consistent with the 1964 plan drawing. The right bank consists of a natural alluvial trace. • Debris from high water was noted above the top of riprap (estimated to be elevation 12 feet) which makes the FENIA projected flood elevation of 8.2 feet questionble. • Site observations confirmed the recent cross-section data, which indicates that the bank has been ova locally in the area of ripmp placerreat. The ripmp appears to be distressed, as indicated by apparent movement of the ruck on the slope, pockets indicating absence or poor interlocking of the rook, and its stemma. Additionally, several trees on the slope are overhanging, resulting in additional stress to the bank. ▪ Ovetsteepeoing of the slope was also noticed from the north end at the limber bulkhead wall at.Greenbaum's to the beginning of rim. Shallow slide scarps were observed in this area. 4.3 owswigatEseasms_asamisitaaitanlaugam' In our opinion, the debiting bank protection is inadequate for the life of the pada* (estimated to be at least 20 years). Bawd on FEMA studies, we undastand that the 100- year storm water elevation for the river at the site is 8.2 feet and mean channel velocity is 4.4 feet per second (fps). Considering the geometry of the river channel, the vdocity of the W4973-97 4 +20638252 =' Jti -- PARSONS BR I NCKERHOFF F-987 T -939 P -006 JUN 21 '94 13:04 SHANNON 4WUL,SON.INC. river along the outside of the bend (left bank) was estimated at 6A fps (Reference 2) which is sufficient to erode the fine sands and silts below the toe. Based on preliminary riprap design calculations, we estimate that 18- inch - diameter riptap would be suitable to provide bank protection. The existing riprap is of this size or larger; however, as shown on the 1964 plan, the rock apparently was not keyed into the river bottom and consequently is being undermined and is failing. Based on our experience, inadequate the protection is the leading an of revetment failures and is likely the major cause far the c umently observed ovaste�n of the bank in the site area. In our opinion, the observed undermining and toe erosion which has occurred aver the lart 30 years will continue and cause further oversteepeeting, if left unchecked. VKe anticipate that in the short teQn, failure of the slope will primarily be shallow and gradual in nature, resulting from Progressive oversteepening of the slope. It is our opinion that it is mililorly that a single storm event would cause a rapid retreat of the bank to the bike trail. In the long- term, this pznogressive overstee. ping could result in a large slide or ae t' down of the slope, possibly affecting the proposed bike trial. With respect to overall slope stability, it is our opinion that construction of the bike trail would have negligible effect on the stability of the slope (i.e., placement of the wills and trail will not decrease the stability of the slope beyond existing conditions). The bike trait may, howeier, increase the consequences associated with a slope failure by providing human access close (within 25 feet) to the area of concern. Based on our site observations, preliminary engineering studies, and our =patience, we recommend the following measures. • lb provide for long-term stability of the bike trail will system, a plan should be impbxnented for bank s abili2ation by the use of riptap. Riptap should be placed on a 2H:1V slope from the end of the umber bulkhead wall Station Br 31+00 to about Station % BT 39 +00. Based on our understanding of the subsurface conditions, it appesazs that the toe of the slope is composed of clean sands that are very susceptible to erosion. 'lb provide adequate bank protection, a 3- to 4-feet- deep key below the river bottom would be requited for the rock to reduce the susceptibility to scour and undermining. The existing xipsap mat ale will be suitable for reuse. • In the event that the stabilization of the river bank is delayed, we recommend that the rate of regression of the slope be regularly monitored, especially during and after major stoma events. The disadvantage to delaying any stabilization grail the W- 5973-97 5 +20E3025" =', PARSONS 5R I NCKERHOFF F -987 T -939 P -007 .JUN 21 '94 13:05 SHANNON &WILSON, IN problem is mem, is the long -term commitment =wind to paopedy monitor and evaluate the condition of the bank, especially as a majority of it is under water sod not visible. Additicmally, if conditions of concern are noted, the time for pig for site stabilization measures may be too Long. Also, with respect to . sdiedalhrg construction :elated to bank protection, k is our opinion that access from the freeway to the bank may not be practical after the bile tali and the associated %calls have been constructed. A portion of the lower wall and twirl v uld Ii7aeiy be damaged to implement such a fix. Unless it is practical to provide construction aeoess from the river, it is our opinion that this work should be scheduled before the construction of the bike nail. • As a minimum, consideration should be given to the immediate Stab/linden of the currently unprotected 100 feet of the river bank north of Station % BI' 31 +00 (by GGcenbaurns) tiuvugh the placement of properly defined rpsap, M an alterative, the existing timber piling currently protecting the Glum parking area could be extended to the nab to the incising Tiptop to provide protection to this portion of the slope (which is rwe steepened and unprotected). The disadvantage of instilling piling is that it would lxlaely cause the river to dive deeper; causing additional scout The advantage of installing piling is that its construoion could be accomplished above the ordinary high water level, thereby seducing the permitting requirements.

DRAFT ADDENDUM NO. 1 TO PHASE 2 GEOTECHNICAL REPORT DESIGN RECOMMENDATIONS FOR RETAINING WALLS NW-1 AND RW-2 SR-5 TUKWILA TO LUCILE STREET HOV LANES KING COUNTY, WASHINGTiON 1.0 INTRODUCTION This addendum presents design recommendations for retaining walls NW-1 and RW-2 for the referenced project. This document is an addendum to our Phase 2 Geotechnical Report for Bridges, Retaining Walls, and Major Earthwork Areas, dated June 1994. The two walls are listed below: 1. NW-1: Station $ Br 28 +98 LT to IL 2641 +87 RT 2. RW-2: Station IL BT 29 +25 to 38 +75 RT The purpose of this study was to evaluate the subsurface conditions along the proposed alignment of the walls, and to address specific concerns associated with river bank erosion and slope stability. 2.0 PROPOSED IMPROVEMENTS As part of the SR-5 HOV lane improvements, a bike trail will be constructed along the left bank of the Duwamish River, under the south end of Bridges 5/526 E and W, along SR-5 to Interurban Avenue. In this area of the project, the river makes several sharp bends, most noticeably a tight, U- shaped bend at the south end of the proposed bike trail (see Figure 1). A major portion of the trail will be constructed at grade or with only minor grading. Two retaining walls will be required, however, as the bike trail moves from the edge of the river and cuts across the roadway embankment to Interurban Avenue (Figure 1). The upslope wall (NW-1) will be about 1,280 feet long and will have a design height ranging from 5 to 14 feet. We understand that this wall will be a non - standard, concrete, cantilever retaining wall with an integrated traffic barrier and noise barrier wall. The downslope wall (RW-2) will be about 950 feet long, and will have a design height of 7 to 8 feet. We understand that this wall is planned as a standard, concrete, cantilever retaining wall to be designed in accordance with the Washington State Department of Transportation (WSDO(F) Standard W- 5973 -97 1 SHANNON ?;WILSON, INC. Plan D -lb. This lower wall will generally parallel the river. At its nearest location, the wall will be approximately 25 feet (horizontally) from the river bank. 3.0 EXPLORATIONS Description of methods and results of our field exploration program (except borings BN -9 and BN -10) are presented in Appendix A of the Phase 2 Geotechnical Report dated June 7, 1994. The station, offset, elevation, depth, and rig type for each boring are also indicated on Table A-1 in the above - referenced Appendix. Pertinent information regarding previous borings at this site (PP -25, PP -26, and MH -27) are presented in Appendix C of the above - referenced report. Borings BN -9 and BN -10 were advanced as part of the supplemental exploration program dated September 1993. These borings were advanced on October 28, 1993. The borings were drilled using a skid rig provided by Boretec, Inc. of Seattle, Washington, under subcontract to Shannon & Wilson, Inc. For a detailed description of this drilling method, please refer to Appendix A of the above - referenced report. 4.0 LABORATORY TESTING Details and results of the geotechnical laboratory testing performed on samples from the current borings (except BN -9 and BN -10) are included in Appendix B of the June 7, 1994 Phase 2 report. Two mechanical grain -size analyses were performed on selected samples of borings BN -9 and BN -10 to determine grain -size distributions. The results are presented on Figure 15. Please refer to Appendix B of the above - referenced report for a description of the testing procedure. In addition, wash sieve analyses were performed on selected samples to determine the percentage fines. The tests indicated 71.0 and 2.9 percent fines for samples S -6 and S -7 of boring BR-4, 11.8 and 14.7 percent for samples S -9 and S -10 of boring BR-5, and 38.8 and 95.7 percent for samples S -5 and S -6 of boring BR-11. 5.0 SUBSURFACE CONDITIONS Our interpretation of subsurface conditions along the alignment of the proposed walls is based on borings BN -9 and BN -10, BR-4 through BR-6, BR-11 and BB -21, as well as W- 5973 -97 SHANNON :;WILSON, INC. borings PP -25, PP -26, and MH -27 completed previously by the WSDOT The approximate location of these borings are shown on Figure 1. Two generalized cross - sections showing the approximate location of the walls with respect to existing topographic features are presented on Figures 2 and 3. Subsurface conditions along the walls are graphically depicted on the Generalized Subsurface Profile, Figure 4. In general, the borings encountered 5 to 38 feet of fill, down to elevation 6 to 10 feet (City of Seattle datum). The fill consisted of very loose to medium dense, silty, gravelly SAND, sandy SILT, and sandy GRAVEL. Gravel -sized sandstone fragments were encountered at the bottom of the fill layer in boring BR-6. Cobbles were inferred from drilling action near the bottom of the fill layer in boring BN -10. The fill was generally underlain by about 10 to 15 feet of loose to medium dense silty, fine SAND and fine sandy SILT (down to elevation -2 to -10 feet). South of about Station BT 36 +00, the SAND /SILT sequence included a 5- foot -thick layer of soft to medium stiff, slightly clayey to clayey SILT (from elevation +1 to -4 feet). The SAND /SILT was underlain by loose to dense (generally medium dense), clean to slightly silty, fine to medium SAND in all of the borings except boring BB -21. In this boring, the fill and SAND /SILT were underlain by medium dense (grading to very dense), silty, fine SAND and fine sandy SILT to about elevation -45 feet. This layer was underlain, in order of increasing depth, by medium stiff CLAY (from elevation -45 to -57 feet), medium dense to very dense SAND (to elevation -104 feet), and very stiff CLAY to the bottom of the boring (elevation -108 feet). No observation wells were installed in the borings upon completion of drilling. During drilling, groundwater was measured at elevations of about 16 feet, 6 feet, and -3 feet in borings BR-11, BN -9, and BN -10, respectively. No groundwater was encountered in the other borings during drilling, although a majority of these borings were completed using mud rotary techniques, which does not allow observation of a groundwater level. We anticipate that the groundwater level in this area would be influenced by and to be near the elevation of the Duwamish River. 6.0 DUWAMISH RIVER AND LEFT BANK CONDITIONS 6.1 Existing Information As part of our study, we reviewed the following documents provided by Parsons Brinckerhoff Quade & Douglas, Inc. (PB): W- 5973 -97 SHANNON 6WILSON. INC. 1. Design drawings showing the placement of heavy -loose riprap along the left bank of the river in 1964 (Reference 1). 2. Cross - sections based on recent survey by David Evans and Associates (DEA). 3. Federal Emergency Management Agency (FEMA) 1980 data showing a cross - section in the vicinity. Each of these documents is discussed below. The 1964 design plan indicates that heavy -loose riprap was to be placed along the left bank of the river from about Station $ BT 32 +30 to 38 +00 during original freeway construction. The riprap was to be placed to elevation 12 feet on a 1.5H:1V slope. No bottom elevation of the rock was indicated; however, the drawing suggests that the riprap was placed on the river bottom and not embedded. The recent cross - sections based on survey by DEA indicate a river bank slope of 0.9H:1V (horizontal to vertical) from Station ) , BT 32 +40 to 33 +20, 1.67H:1V from 33 +20 to 34 +60, 1.25H:1V from 34 +60 to 35 +60, and 0.5H :1V from 35 +60 to 37 +10. North of B BT 37 +10 and south of 32 +40, the recent cross - sections indicate a slope of 1.5H:1V or flatter. An attempt was made to compare the 1980 FEMA cross - section with the recent cross - sections by DEA in order to determine the rate of erosion in the last 14 years. However, it was not possible to precisely locate the FEMA cross - section because it lacked a detailed description and did not correlate well with the existing topography and SR-5 roadway elevation. Making some assumptions regarding the location and elevation of the 1980 cross - section, we concluded that it was taken near Station B, BT 35 +50. Comparing the 1980 FEMA cross - section to the recent one completed by DEA shows that the river bottom elevation in 1980 is similar to that in the recent survey, about elevation -12 feet. A comparison of the bank slope, however, indicates that the slope is flatter today than in 1980. However, because the 1980 cross - section cannot be directly compared to the recent survey, it is our opinion that it should not be relied upon in an evaluation of riverbank processes over the last 14 years. W- 5973 -97 4 SHANNON FIWILSON, INC. 6.2 Site Reconnaissance A site visit was made by representatives from our firm on June 10, 1994 to observe the left bank of the river along the area of interest. Our observations are summarized below. ► Near the south end of the proposed walls at Station BT 31 +00 (behind Greenbaums Furniture Store), the left bank of the Duwamish River is confined by a timber bulkhead. From our discussions with representatives of Greenbaums, we understand that this wall has recently been repaired. Further north (approximately Station B BT 32 +00), the left bank is confined by the fill embankment placed along the river bank for the construction of the SR-5 roadway. The first 100 feet of the left bank beyond the bulkhead is unprotected; beyond this area the river bank is protected by riprap. The approximate extent of riprap protection and its size (i.e., large size rock similar to heavy -loose riprap) is consistent with the 1964 plan drawing. The right bank consists of a natural alluvial terrace. ► Site observations confirmed the recent cross - section data, which indicates that the bank has been oversteepened locally in the area of riprap placement. The riprap appears to be distressed, as indicated by apparent movement of the rock on the slope, pockets indicating absence or poor interlocking of the rock, and its steepness. Additionally, several trees on the slope are overhanging, resulting in additional stress to the bank. Debris from high water was noted above the top of riprap. ► Oversteepening of the slope was also noticed from the north end of the timber bulkhead wall at Greenbaum's to the beginning of ripap. Shallow slide scarps were observed in this area. 6.3 Conclusions Regarding Adequacy of Existing Bank Protection In our opinion, there is a low risk of instability of the SR-5 roadway embankment in this area based on current conditions. However, the existing bank protection is inadequate for the life of the project (estimated to be at least 20 years). Based on FEMA studies, we understand that the 100 -year storm water elevation for the river at the site is 8.2 feet and mean channel velocity is 4.4 feet per second (fps). Considering the geometry of the river channel, the velocity of the river along the outside of the bend (left bank) was estimated at 6.4 fps (Reference 2) which is sufficient to erode the fine sands and silts at the river bottom. Based on preliminary riprap design calculations, we estimate that 18- inch - diameter riprap would be suitable to provide bank protection. The existing riprap is of this size or larger; however, as shown on the 1964 plan, the rock apparently was not keyed into the river bottom and consequently is being undermined and displaced. Based on our experience, W- 5973 -97 5 SHANNON 6WILSON, INC. inadequate toe protection is the leading cause of revetment failures and is likely the major cause for the currently observed oversteepening of the bank in the site area. In our opinion, the observed undermining and toe erosion which has occurred over the last 30 years will continue and cause further oversteepening, if left unchecked. We anticipate that in the short-term, any failure of the slope as a result of further erosion would primarily be shallow and gradual in nature, resulting from progressive oversteepening of the slope. It is our opinion that it is unlikely that a single storm event would cause a rapid retreat of the bank to the bike trail. In the long -term, this progressive oversteeping could result in a large slide or set -down of the slope, possibly affecting the proposed bike trial. With respect to overall slope stability, it is our opinion that construction of the bike trail would have negligible effect on the stability of the slope (i.e., placement of the walls and trail will not decrease the stability of the slope beyond existing conditions). The bike trail may, however, increase the consequences associated with a slope failure by providing human access to within 25 feet of the area of concern. Based on our site observations, preliminary engineering studies, and our experience, we recommend the following: ► lb provide for long -term stability of the bike trail wall system, a plan should be implemented for bank stabilization by the use of riprap. Riprap should be placed on a 2H:1 V slope from the end of the timber bulkhead wall Station 1B BT 31+00 to about Station B BT 39 +00. Based on our understanding of the subsurface conditions, it appears that the toe of the slope is composed of clean sands that are very susceptible to erosion. To provide adequate bank protection, a 3- to 4 -feet- deep key below the river bottom would be required for the rock to reduce the susceptibility to scour and undermining. The existing riprap materials will be suitable for reuse. ► In the event that the stabilization of the river bank is delayed, we recommend that the rate of regression of the slope be regularly monitored, especially during and after major storm events. ► Consideration should be given to the immediate stabilization of the currently unprotected 100 feet of the river bank north of Station B BT 31 +00 (by Greenbaums) through the placement of properly designed riprap. As an alternative, the existing timber piling currently protecting the Greenbaum parking area could be extended to the north to the existing riprap to provide protection to this portion of the slope (which is oversteepened and unprotected). The disadvantage of installing piling is that it would likely cause the river to scour deeper. The advantage of 6 W- 5973 -97 SHANNON EIWILSON, INC. installing piling is that its construction could be accomplished above the ordinary high water level, thereby reducing the permitting requirements. 7.0 DESIGN RECOMMENDATIONS 7.1 Bearing Capacity and Settlement We understand that both walls will be designed as concrete retaining walls. Table 1 provides soil parameters for design of these walls. As indicated in the table, Wall NW-1 could be designed for an allowable bearing pressure of 1 ton per square foot (tsf) south of Station 11., BT 36 +00, and 1.5 tsf north of it. Wall RW-2 could be designed for an allowable bearing pressure of 1 tsf. These values include an FS of at least 2. Low allowable bearing pressures are recommended for Wall RW-2 and the south one -half of NW- 1 to account for the low strength of native soils encountered below about elevation 6 to 10 feet. The footing for the north one -half of Wall NW-1 will be situated higher in the fill above the loose and soft native soils, and therefore can be designed for a higher allowable bearing pressure. Settlement of the walls is anticipated to be less than 1/2 -inch for the portion of the alignment north of Station BT 36 +00. South of Station B BT 36 +00, the alignment is underlain by a 5 -foot -thick layer of soft to medium stiff, slightly clayey to clayey SILT, as discussed in Section 5.0. In this area, the total settlement of the walls is anticipated to be about 1-1/4 - inch to 2 inches, of which 1 to 1 -1/2 inches is expected to occur within 15 to 30 days of load application. The remaining 1/4- to 1/2 -inch settlement is expected to occur over the next 20 years. To reduce the effect of the settlement on the performance of the walls, it is our opinion that a structural earth wall (SEW) should be considered for Wall RW-2. The upper wall, NW-1, could be constructed and allowed to settle for approximately 30 days before the noise barrier is placed, to reduce post - construction settlement. We estimate that this procedure could reduce the post- construction settlement to less than 1 inch. Another alternative would include deep foundation support for Wall NW-1. We can provide recommendations for such support, if required. In our opinion, the compressible soils located between elevation +1 and -4 feet are too deep to overexcavate and replace to reduce the magnitude of settlement. 7 W- 5973 -97 SHANNON flWILSON. INC. Additionally, these soils are located below the groundwater table, making excavation difficult and expensive. 7.2 Liquefaction The potential for liquefaction at the wall locations was evaluated based on the subsurface conditions encountered in the current borings and our review of previous exploration logs. Based on a method developed by Seed and Harder (1990), the FS against liquefaction was estimated from Standard Penetration Test blow counts obtained in the field for various fines contents. The fines content of soil samples was estimated by visual examinations, mechanical grain -size analyses, and wash sieve analyses performed on selected samples. Depending upon their fines content, the soils were classified into three groups: (1) clean to slightly silty sand 10 percent fines), (2) slightly silty to silty sand (10 to 35 percent fines), and (3) silty sand, silt, and other soils (> 35 percent fines). Depending on their in situ density, soils in group 1 or 2 may be liquefiable. Generally, the possibility of liquefaction of soils in group 3 decreases with increasing fines content and /or increasing clay content (i.e., cohesion), but soils in this group may experience strength reduction during an earthquake. For each recorded N -value in cohesionless materials, the corrected N -value and the corresponding cyclic stress ratio required to cause liquefaction was determined. An equivalent cyclic stress ratio for a design earthquake of magnitude 7.5 with a maximum ground acceleration of 0.27 times gravity was used for the analysis. The FS against liquefaction is defined as the cyclic stress ratio to cause liquefaction divided by the equivalent earthquake - induced cyclic stress ratio. Based on the results of our analyses, it is our opinion that south of Station BT 36 +00, the wall alignment is underlain by a layer of potentially liquefiable soils. This layer primarily consisted of clean to slightly silty SAND, and was encountered below elevation -5 feet in the borings. Liquefaction of this layer could result in lateral spreading of the embankment and settlement of the roadway. North of Station B BT 36 +00, our analyses indicated an FS of about 1 against liquefaction. The fines content and relative density of the potentially liquefiable zone in this portion of the 8 W- 5973 -97. SHANNON 6WILSON. INC. alignment is similar to that of soils encountered at the south abutments of Bridges 51526E and W. As discussed in the Phase 2 Geotechnical Report dated June 7, 1994, we recommend additional borings, laboratory testing, and analyses to better assess the potential for liquefaction in this area. 7.3 Slope Stability Studies were done to evaluate the stability of the slope under static and seismic loading under current conditions. Slope stability analyses were performed using the computer program PCSTABL5M (Reference 3). The stability initially was evaluated in terms of existing static conditions (Case 1). Case 2 was analyzed by applying a horizontal force at the centroid of the sliding zone (pseudo- static analysis). This force was taken as a percentage of the total weight of the sliding zone, with the percentage defined as a seismic coefficient. For this study, a seismic coefficient of 0.135 was used, which is one -half of the acceleration coefficient for this project. This coefficient is also approximately equal to the value recommended by the U.S. Army Corps of Engineers (1982) for this seismic risk zone. A third case was analyzed assuming 20 percent strength loss in the potentially liquefiable soils during ground shaking (as simulated by the seismic coefficient). Finally, a fourth case was analyzed where liquefaction was assumed at the end of ground shaking and the liquefied soil was assigned a residual strength of 200 psf based on a procedure recommended by Seed and Harder (1990). For Cases 3 and 4, wedge failure was assumed through the potentially liquefiable soils. The results of our analyses are summarized below. Our studies indicate that the slope is stable under static loading conditions (although with an FS lower than typically used for design), but would have an inadequate FS under seismic loading conditions. Case Conditions FS Against Slope Instability 1 Static 1.3 2 Pseudo - static (k= 0.135) 0.9 3 Pseudo - static (k= 0.135) and reduced strength 1.0 in potentially liquefiable zone 4 Post - shaldng liquefaction with residual strength of 200 psf in potentially liquefiable zone 9 0.5 W- 5973 -97 SHANNON &WILSON, INC. The low factors of safety during seismic loading conditions indicate that lateral spreading of the embankment and /or slope failure would likely occur. It is our understanding that under the current WSD(I' guidelines soil improvements to mitigate potential soil liquefaction are not required. SHANNON & WILSON, INC. James F. Zitnik, P.E.

Line S. 336th St. to S. 272nd St. The Stage 1 project is currently planned to begin construction during the fall of 1993. It is estimated that the final stage will not be constructed for 7 to 10 years. 7. Are there any plans for future additions, expansions, or .further activity related to or connected with this proposal? If yes, explain. The project being proposed in this document is an important element in the Puget Sound High. Occupancy Vehicle (HOV) system. It would provide an integral link between the SR 5 system and the remaining I 405 segment proposed for completion in the mid to late 1990s. The project would expand HOV services southward to Tacoma and strengthen the HOV system. The project will improve the level -of- service for buses, van pools, and car pools and help transit services maintain their schedules. HOV lanes, metered ramps, park -and ride lots, and HOV bypass lanes are all components of the regional HOV system. The construction of HOV lanes through this section of SR 5 will provide much - needed support for the existing and planned park- and -ride lot system along this corridor. 8. List any environmental information you know about that has been, or will be prepared, directly related to this proposal. This Checklist is the only environmental documentation that will be circulated for this proposal. 9.. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by the proposal? If yes, explain. No. 10. List any government approvals the proposal, if known. This project could require some or approvals: Federal Nationwide Permit by U.S. Army Corps of Engineers Individual Permit by U.S. Army Corps of Engineers or permits that will be needed for all of the following permits or State NPDES Department of Ecology 401 Water Quality Certification Department of Ecology Temporary Water Quality Modification Department of Ecology Water Pollution Control Plan Department of Ecology Hydraulic Project Approval Department of Fisheries Local The "Growth Management Act" procedures (WAC 365 -195) required local agencies to establish comprehensive plans and regulations. This process is currently under way. At this time it is not possible to develop a comprehensive list of permit requirements. WSDOT will coordinate with the local agencies with jurisdiction and comply with all applicable ordinances. 11. Give brief, complete description of the project including (but not limited to) it's size, general design elements, and other factors that will give an accurate understanding of it's scope and nature. There are several questions in this checklist that ask you to describe certain aspects of the proposal. You do not need to repeat those answers on this page. This project proposes to improve a segment of SR -5 by constructing high occupancy vehicle (HOV) lanes from the vicinity of the Fife Interchange in Pierce County (MP 137.45) to the intersection of SR 5 and SR 405 at the Tukwila (Southcenter) Interchange (MP 154.46), within the City of Tukwila. The HOV lanes will be created by widening the existing roadway towards the median. In addition to the HOV lanes, the following items of work are proposed: 24 mainline structures will be widened to accommodate the new roadway width. All the existing bridge rails will be replaced and upgraded to current standards. ' . All on -ramps that do not currently have the capability will be widened for HOV bypass lanes. A truck climbing lane will be added to southbound SR 5 from the Tukwila Interchange to SR 516 (Kent /Des Moines Road). A Surveillance, Control, and Driver Information (SC &DI) system will be installed for the entire project corridor. Ramp metering will be added to all on- ramps. 3 An interim HOV project within the limits of this proposal was completed in 1991 and is currently operational. The interim lanes,• northbound from S. 272nd St. to S. 200th St. and southbound, Klickitat Dr. to SR 516 are currently operating with reduced lane and shoulder widths. This section will be upgraded as part of this project. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of the proposed project, including a street address, if any, and section, township and range, if known. If the proposal would occur over a range of area, provide the range boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. This project would begin at the Fife Interchange at 54th Avenue East in Pierce County (MP 137.45) and extend northward to the intersection of SR 5 / SR 405 at the Tukwila (Southcenter) Interchange (MP 154.46), a distance of approximately seventeen miles. See attached vicinity map. B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site: (flat, rolling hills, steep slopes, mountainous, other). This proposal traverses terrain ranging from flat at the southernmost end of the project to rolling and hilly. b. What is the steepest slope on the site (approximate percent of slope) ? The steepest slopes within the project limits are approximately 2:1 (50 percent). These slopes occur on the sidesiopes of existing roadside ditches and around bridge ends. c. What general types of soils are found on the site (e.g., clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The proposed project is located almost entirely within the existing right -of -way of SR -5, and ground surfaces subject to construction disturbance will be primarily areas previously disturbed during construction of the original SR -5. Much of this earth material is characterized as non - native fill material. d. Are there any indications of a history of unstable soils in the immediate vicinity? If so, describe. No. e. Describe the purpose, type, and approximate quantities of any filling or grading—proposed. Indicate source of fill. • The estimated total amount of excavation required for the project is estimated at 558,000 cubic yards. The estimated total amount of fill required is 571,000 cubic yards. f. Could erosion .occur as a result of clearing, construction, or land use? If so, generally describe. Short -term construction related impacts to earth will consist of increased potential for erosion and sediment laden runoff. g. About what percent of the site would be covered with impervious surfaces after project construction (e.g., asphalt, buildings)? Approximately 60% of the project site will be covered by imperviously paved surfaces after construction, an increase of 20 %. h. Proposed measures to reduce or control erosion, or other impacts to the earth; if any: Erosion and sediment impacts will be minimized by adherence to the following general principles of erosion control and best management practices during construction. Additional and more specific measures may be made part of construction contracts. General guidelines for erosion and sediment control: The contractor will follow these guidelines while designing and constructing all erosion and sediment control measures. These measures will be part of the construction'contracts, and continuous on -site monitoring will ensure the following principles are implemented during all construction activities. Implement erosion and sediment control measures prior to clearing or grading, throughout construction and after construction. Reduce the velocity of run -off from construction areas with proper control measures and minimize the volume of construction run -off flowing across bare soil areas by planned diversions. Provide temporary or permanent drainage facilities to control the run -off released from the construction area, with an emphasis on source isolation. Clear only those areas which will be graded and stabilize during the current season. Exercise care to preserve the natural landscape; conduct all operations to prevent any unnecessary destruction, scarr'ng, or defacing of the natural surroundings throughout the project area. Maintain all temporary erosion /sediment controls in a satisfactory condition until such time that clearing and construction is completed, permanent drainage facilities operational, and there is no longer the potential for er Adherence to these measures, and to any further measures requ state or local plans, permits or ordinances, is expected to p erosion and sedimentation impacts or reduce them to an insign level. 2. Air a. What types of emissions to the air would result proposal(e.g., dust, automobile, odors, industrial, wood during construction and when the project is completed? generally describe and give approximate quantities, if known. The only emissions that would result from this proposal are automobile emissions. WSDOT has completed an air quality study for this project tit 5: Fife To Tukwila Interchange" dated. October, 1992. The stud that in the 2010 design year, this project would represent an improvement over the 1990 existing condition. This project is in an air quality non - attainment area for car monoxide and ozone so it must conform with the State Implemen Plan (SIP) to meet the National Ambient Air Quality Standards current SIP for this area was approved by the EPA on February 1983. This project is included in the Puget Sound Regional Council Transportation Improvement Program (TIP) as amended. This has been modeled and found to conform with the current SIP. this project will not create any new violations nor contribu frequency or severity of any existing violations of the ozone. With its inclusion into the current conforming project will not delay the timely attainment of the NAAQS and carbon monoxide. or are sion. red by event ficant rom the smoke) If any, ust and ed "I- found on ation . The 28, s (PSRC) project As such, e to the QS for IP, the or ozone During construction, it is expected that there will be a temporary increase in dust, other particulate matter, and hydrocarbons. These are caused by increased truck and heavy machinery traffic, removal, and /or placement of materials, and paving operations. The other construction impacts (odors) of the build alternative cannot be quantified. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. No. c. Proposed measures to reduce or control emissions or other impacts to the air, if any: To mitigate the impacts of construction, contract specifications will be written so that those performing the construction work will be in compliance with all federal, state, and local air quality regulations. These regulations cover temporary highway construction impacts such as dust, smoke, and emissions. Burning will not be permitted. 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. There are many small drainage basins within the project limits, all of which ultimately drains into Puget Sound through a system of tributaries. In the southern portion of this vicinity of SR 18 to the south, Commencement Bay by the Hylebos project, from approximately the . the project is drained into Creek system. The remainder of this project, from the SR 18 vicinity, north to Tukwila, the surface water flow makes its way into the Duwamish /Green River system then to Puget Sound at Elliot Bay. 2) Will the project require work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Yes, the project will require bridge construction over Hylebos Creek. In addition lane construction will occur within 200 feet of the creek or one of its tributaries in several locations. 7 WSDOT has conducted a wetland inventory for this project. 17 wetland areas have been inventoried within the proximity of this project. The area that wetland impacts would occur as a result of this project begins at the Fife Interchange (54th Ave. E.) and continues towards S. 375th Street near the boundary line separating King and Pierce Counties. This area is in the final stage of construction for this project and is not scheduled for construction until after the year 2000. No detail information on impacts is available at this time. During the detail design of this Stage 7 of this project all impacts to wetlands will be avoided wherever practical. Where this cannot be achieved, impacts will be minimized to the greatest extent possible. Unavoidable impacts to wetlands will require compensatory mitigation. Wetland mitigation will be in accordance with all applicable State, Local and Federal regulations existing at the time of design and construction. 3) Estimate the amount of fill and dredge material that would be placed in or, removed from surface waters or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. This information is not available at this time. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose and approximate quantities, if known. No. 5) Does the proposal lie within a 100 year floodplain? If so, note location on the site plan. Yes, the proposal crosses the floodplain of Hylebos Creek south of the King / Pierce County Line. 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. b. Ground 1) Will ground water be withdrawn, or will . water be discharged to groundwater? Give general description, purpose and approximate quantities, if known. No. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (e.g., 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 served (if applicable) or the number of animals or humans the system(s) are expected to serve. None. 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 will this water flow? Will this water flow into other waters? If so, describe. An increased quantity of surface run -off will occur resulting from a net increase of impervious surface of approximately 60 acres. This run -off will run into the surface waters previously described by way of the highway drainage system. 2) Could waste material enter ground or surface water? If so, generally describe. No, not as a result of this project. d. Proposed measures to reduce or control surface, ground and runoff water impacts, if any:. Mitigation of water quality impacts during construction will involve standard erosion and sedimentation control measures, as well as scheduling, revegetation, and other practices identified under the EARTH section. A Water .Pollution Control Plan will be prepared and ' submitted to the Department of Ecology for approval. The contractor will be required to prepare an accidental spill cleanup plan and implement the plan if needed. The plan will include site specific conditions to be developed at the time of final design. In addition, the following general measures will be required during all construction activities. No construction activities are to occur in flowing water except as may be necessary to construct crossings or barriers. Material from construction work (i.e., soil, rock and other debris) shall not be discharged to surface water nor deposited where it could be eroded and carried to the stream by surface runoff or high stream flows. Disturbed soil areas and fill slopes shall be stabilized. There shall be no unnecessary damage to riparian vegetation. All work within the riparian zone will be coordinated with the State Departments of Fisheries or Wildlife. 9 There shall be no discharge of petroleum products, cement, cement washings or other construction materials to surface waters. Where working areas encroach upon live streams, barriers shall be constructed that are adequate to prevent the flow of turbid water into the stream. Compliance with the terms and conditions of the Hydraulic Project Approval, and Waste Discharge Requirements, if needed, will assure the protection of water quality. Adherence to the terms and conditions of these measures will prevent significant impacts to water quality of receiving waters during Construction. Long -term surface water runoff impacts will be mitigated by measures .including detention ponds and storm drainage facilities. These measures will be developed and designed in coordination with the Department of Ecology (DOE) and King and Pierce Counties. Measures will include following recommendations in the DOE's "Stormwater Management Manual for Puget Sound Basin ", the "King County Surface Water Design Manual" and consistent with the "Hylebos Creek Drainage Basin Management Plan ". These measures will prevent significant long -term water quality impacts. The proposed project does not include any withdrawals from or discharges to . ground water. No impacts to ground water are expected. This project will be designed to be consistent with local agency regulations for detention and retention of highway runoff and with the DOE " Stormwater Management Manual for the Puget Sound Basin" for water quality. 4. Plants a. Types of vegetation found on the site. Due to the size of this project, the site covers a wide range of vegetation types. The predominate environment is highway median with grasses, shrubs and small trees. b. What kind and amount of vegetation will be removed or.altered? Approximately 70 acres of vegetation would be disturbed by this project. Almost all of this vegetation loss is limited to the highway median consisting of shrubs and grasses with some trees. c. List threatened or endangered species known to be on or near the site. None. c d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: To the greatest extent possible, vegetation removal during construction will be minimized. The disturbed areas will be regraded and revegetated to blend with the surrounding area in accordance to an approved landscape plan. 5. Animals a. Birds or animals are known to be on or Hawk, eagle, heron, rodents). which have been observed on or near the site or near the site. songbirds and small mammals (racoon, skunk, b. List any threatened or endangered species known to be on or near the site. None known. c. Is the site part of a migration route? If so, explain. No. d. Proposed measure to preserve or enhance wildlife, if any: This project will remove some habitat for the land animals but should not change the diversity of the animal population. It should have minor adverse impacts to land animals in the project vicinity. Overall this project should have an insignificant impact on wildlife in the area. Other than the revegetation and wetland mitigation described, no other wildlife preservation measures are proposed. 6. Energy and Natural Resources a. What kinds of energy (electric, natural gas, oil, wood stove or solar) will be used to meet the completed projects energy needs? Describe whether it will be used for heating, manufacturing, etc. None. b. Would the project affect the potential use of solar energy by adjacent properties? If so, generally describe. No. 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. The completion of an HOV system, by encouraging the reduction single occupancy vehicle use, and thereby moving more people in fewer vehicles, constitutes an energy conservation measure. of 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. Not as a result of this proposal. 1.) Describe special emergency services that might be required. None. 2) Proposed measures to reduce or control environmental health hazards, if any: None required. b. Noise 1) What types of noise exist in the area which may affect your project (e.g., traffic, equipment, operation, other). None. 2) What types and levels of noise would be created by or associated with the project on a short term or long term basis (e.g., traffic, construction, operation, other)? Indicate what hours noise would come from the site. The only noise associated with this proposal is generated by traffic utilizing the facility or equipment noise during construction activities. Noise impacts already occur along this portion of SR 5 the noise levels resulting from completion of this proposal are not significant. WStiOT has eohducted a noise analysis for this project and has determined that this proposal would increase noise levels by approximately 1 dBA over the existing noise levels. There will be temporary increases in noise levels from construction activities. During construction, persons living or working near the project will be exposed to noise generated from the contractor's equipment and operations. Large machinery and trucks delivering construction materials will be the major contributors. This type of noise tends to be intermittent and of a temporary nature. It is anticipated that construction activities will occur primarily during daylight hours. It may be necessary for the safety of the motoring public as well as construction workers to perform certain construction activities at night. 3. Proposed measures to reduce or control noise impacts, if any: Noise barriers were evaluated for each of the impacted residential study areas along the project. WSDOT is utilizing the Federal Highway Administrations noise abatement regulations for this project. These regulations require consideration of mitigation if it is feasible and reasonable to do so and to include those barriers for construction that are effective. A barrier is reasonable and feasible if it can physically and reasonably constructed without jeopardizing safety, health, maintenance, expansion, utilities, and environmental concerns. A noise barrier could be considered effective if substantial reductions in noise are possible and noise impacts could be reasonably eliminated. A 10 dBA noise reduction was considered substantial for conventional barriers. A cost criteria of $8,000 per residence was used for each residence that would have a noticeable improvement from barrier construction. The contractor will be required to adhere to the adopted Washington State Department of Ecology "Maximum Environmental Noise Levels" (WAC 173 -60), regulating construction noise close to residential areas between the hours of 10:00 p.m. and 7:00 a.m. In addition, the contractor will be required to adhere to all applicable local noise ordinances. 8. Land and Shoreline Use a. What is the current use of the site and adjacent properties? The site is currently used for vehicular transportation, adjacent properties are a mixture of residential, commercial and parks /open space. b. Has the site been used for agriculture? If so, describe. No. c. Describe any structures on the site. Not applicable to this project. d. Will any structure be demolished? If so, what?

NARRATIVE DESCRIPTION OF THE PROJECT This project proposes to widen SR5 by constructing a southbound truck climbing lane and an inside HOV lane from the Tukwila interchange to the south 188th interchange. This improvement is located within the interstate right of way in western King County between MP 152.26 and MP 154.38. See vacinity map sheet 1 of 9. This project is part of a long range plan to:complete tfieHOV:system betweena;; . „ 'a`_'. Tukwila: The enormity of the undertaking requires that the =19,mile project be.broken,into;seven.stages to, be accomplished over the next decade. Construction of stage one is scheduled to start fall 1994 and to be completed within 850 working days. Each stage can stand alone on its own merit. Staging allows more contractor the ability to bid on the project and fits WSDOTs fiscal planning. The existing roadway consists of a eight lane divided interstate highway and an interim inside HOV lane southbound from the Tukwila interchange through the project limitsTwoareasof'pavirig iiodifi'cations are proposed. k12' concretetruck'climbing:`lane Mitt a'10'>wide concrete; shoulder wilLabutthe outside existing concrete lane.

The complexity of this corridor (Fife to Tukwila) highway improvement required that it be staged to lessen the impact to cities, counties, public and the environment impacts. Due to the complexity of the drainage systems, steepness of the terrain and staging start date commitments made to the Federal Highway Administration (FHWA), speck segments, will be completed prior to starting other segments. The3HYdtaiilics Rej 'ram the ultimate design of these stages has been submitted to District Hydraulics for review:' Information used in the compilation of this storm water site plan was taken from the submitted report. The name of the report is "Hydraulics Reporrt, Vol. 1, I -5: MP 137.45 To MP 154.38, Fife Interchange to Tukwila Interchange HOV and Truck Climbing Lanes ". Design alternatives were incorporated on this project allowing protection of potential, critical erosion' hazard' areas: 1. Utilize turnpike shoulders and closed drainage system. This alternative was used on some areas to minimize or avoid excavation and the use of retaining walls. 2. Abutting retaining walls along the outside edge of the proposed shoulders to avoid re- cutting or constructing new slopes and lessening the impact to the existing slopes. Jersey Barrier will be mounted on the retaining wall, and catch basins will be located in the shoulder between the barrier and the traveled lane to transport the storm water runoff into the closed drainage system. Jersey Barrier will also be placed along the inside shoulder in breaks between retaining wall locations. It's primary purpose serves as an alternative to guardrail in protecting traffic from rolling down the 2:1 slopes. The added benefit of the barrier is it will act just as the barrier mounted retaining wall in its ability to re- direct the storm water runoff along the shoulder and down the catch basins, as opposed to sheeting down the 2:1 slope. 3. Relocate an existing ditch in the area of the Klickitat Road add lane ramp and the truck climbing lane. This alternative was selected because neither extensive excavation nor retaining walls were required to obtain the standard roadside ditch. 4. Permanent stabilization with proper landscaping design. \A BASINS WITHIN THE PROJECT LIMITS All drainage is located within the Lower Green River Drainage Basin. The sub - basins includes Gulliam Creek and Green River. See attached plan sheet 2 of 9. The Lower Green River Basin is located from South 298th Street to South 164th Street and is contained within the limits of the City of Federal Way, the City of Tukwila, the City of SeaTac, and unincorporated King County. The primary feature of the southern portion of this basin is Bingaman Creek which crossed I -5 in a 42 inch culvert in the vicinity of South 288th Street. Runoff from I -5 in this portion of the basin is conveyed by a series of ditches and pipes that flow into Bingaman Creek. The primary feature of the northern portion of this basin is a pair of streams which cross I -5 in 60 inch culverts north of South 178th Street. All runoff from I -5 within this basin is conveyed by a system of ditches and pipes that flow to the southern most 60 inch culvert and into the Green River.

OFF -SITE ANALYSIS :•or off -site hydraulicianalysis, see the Hydraulics Report entitled "Hydraulic Report, Volume 1, I -5: MP -137.45 To MP 154.38, Fife Interchange to Tukwila Interchange HOV and Truck Climbing Lanes ". This report is available from WSDOT District 1 Hydraulics section. SOIL SURVEY (U.S. SOIL CONSERVATION SERVICE) AmC (Arents): Erodibility - moderate to severe Permeability - 0.20 to 6.00 Depth - 0" to 6" Texture - gravely sandy loam Ur (Urban): Erodibility - slight to moderate Permeability - 0.00 Depth - 0" to 6" Texture - gravely sandy loam to loam LOCATION OF DETENTION AND WATER QUALITY & DETENTION FACILITIES 1 ,�^ SUMMARY OF ALTERNATIVE ANALYSIS -)JJ M ; GU The objective of this analysis was to investigate the proper location of a water quality and detention facility. This facility will treat and detain the run off originated in sub -basin B of our hydraulic report. The criteria used to determine the potential location were topography of the area, existing flow discharge of drainage facilities, and location recommended by City of Tukwila biology and design staff as possible sites. Alternative analyzed are shown in sheet 4 of 9 of the attached plans. As follows the analyzed alternative are summarized and the back up calculation are available upon request for the permit application meeting. Alternative 1 Do nothing. Provide no water quality treatment or detention for this basin. Alternative 2 Biofiltration Swale in median. Provide water quality treatment with a biofiltration swale in the median (vic. LW 2539 +00 right). Alternative 3 Detention/wet pond in median. Provide water quality treatment and detention with a detention/wet pond in the median (vic. LW 2539 +00 right). Iteriufiie*Biofilfeation swale east•of northbound lanes .(Southcenter,location):a,, Provide water quality treatment with a biofiltration Swale east of the I-405 off-ramp (vic. LE 2535 +00 right). 4 :Altenwti e-5 Detention/wet pond . east of northbound lanes ( Southcenter location)' Provide water quality treatment and detention with a detention/wet pond east of the SR405 off -ramp (vic. LE 2335 +00.right). Proposal: Select Alternatives 4 & 5 Alternative 1 is not an acceptable option. Water quality treatment and detention must be provided. Alternative 2 was not selected because of geometric limitations. Design requirements for biofiltration swales include a minimum length of 200 feet and a maximum grade of 6%. Construction of HOV lanes on another project, SR -5 Tukwila to Lucile Street HOV Lanes, will limit the available length for a swale to 75 feet. In addition, the grade in this area exceeds 10%. If this option was selected, detention would need to be provided at a different location. Alternative 3 was not selected due to the existing flow of stormwater and geometric limitations. The majority of the basin stormwater currently flows to a sump point approximately 500 feet south of this location (vic. LE 2534 +00). It would be extremely difficult, if not impossible, to route adequate volumes of water for water quality treatment and detention to this location. In addition, the size and slope limitations cited for Alternative 2 make the construction of a detention/wet pond in the area unfeasible. Alternative 5 was selected because it provides water quality treatment and detention within the constraints of existing stormwater flow and geometry. Although Alternative 5 fully satisfies both water quality and detention requirements, Alternative 4 was also selected to provide additional water quality treatment. The _futal.configuration will be a two -cell detention/wet pond followed by a 200 foot long biofiltration: swale. CITY OF TUKWILA CONCERN ISSUES From predesign meetings between City of Tukwila and our design office, some design and environmental iLssu eeded to be addressed into the design. The following is a summary of them and how they were incorporated- uito- the-design:- -' • Third cell of Southcenter Detention -Pond As shown in the detailed plan of the pond the third cell was redesigned as a bio -swale where the runoff flow will be treated for pollutant removal. — - Also, landscaping treatment to avoid erosion was added due to the steep slopes and irrigation conditions existing in this location. See detail in sheet 7 of 9. •Separation of Klickitat drainage: As shown in the attached plans, the Klickitat run off flow is by passed the third cell of the new detention ;pond as requested. The only situation were the runoff will mix will be during the two year extraordinary rain flood. The emergency bypass will be functioning when the detention pond capacity get a critical two year flow storm. See detail in sheet 3 of 9. •South Center Vegetative screening As shown on theplana, a conceptual design was developed by our landscaping section in accordance ''will lie ti'iY1cv�ila:GBD ee'pIan Also, the surrounding area was enhanced according city of Tukwila standards. See sheet plan 8 of 9 for detail. 5 REaVV .0 CITY OF TUKWILA CiiAi PEEWIT CENTER' •Klickitat Ramp Bio-swale design As shown on the attached plan a small emergent wetland is present on the East side of the new truck climbing lane. The project impacts the wetland buffer but does not impact the wetland. City of Tukwila showed a preference of building a bio -swale at that location as wetland buffer mitigation, because of slope stability and the topography of the nearby area. To address this concern, a proposed new bioswale design is attached for your review as wetland mitigation. There will be no soil nor slope disturbance nearby the right of way hill. Vegetation and erosion landscaping was designed to avoid erosion or bank failure in the area. STORM WATER MANAGEMENT CONSIDERATIONS Stream Bank Erosion Control There is one perennial stream located in the South Center area that will be affected by this project. To avoid stream bank erosion from the increased runoff, a two cell wet detention pond, and biofiltration swale have been chosen as the BMPs. The combination of these BMPs will reduce the frequency and the magnitude of flow conditions. Refer to the drainage plans for more details. Water Quality Treatment BMPs The redevelopment of the site will result in new impervious areas which will require runoff treatment to reduce pollutant loads. Water quality treatment is provided in sub - basins which have new impervious areas greater than 5000 square feet. The identified sub - basins will treat the total comprised area of new impervious surfaces. We will also be treating a significant portion of the existing run off. A two cell wet detention pond and biofiltration swales have been chosen as the BMPs for these sub- basins. Ni The wet pond followed by a 200 ft biofiltration swale will be located between SR5 Northbound and the Southcenter exit ramp. Runoff from 1 -5 in this portion of the basin will be treated in the wet pond and in the adjacent biofiltration swale before it is conveyed to Gilliam Creek then to the Green River. Another biofiltration swale will be located between station LE 2481 +50 to LE2483 +50, north of S.178th st UC on the east side ditch of SR5 Northbound. This biofiltration swale will treat the runoff from I -5 before it conveyes to the South Canyon Vaults located at city of SEA -TAC. These BMPs will treat conventional and nutrient pollutants. A ing wall will be constructed from station G 38 +50 to G 41+00 in the vicinity of the detention-pond located by Southcenter exit ramp due to the geometric constraints of the area. In order to make the proposed biofiltration swale upto standard the final side slope on the site has to be as steep as 1.5:1. A vegetation screening was designed our aping section as directed by the City according to the CBD plan tree. See details attached A 200 ft biofiltration swale will be located between SR5 Southbound at approximate LW station 2526+00 to 2528+00. Run off from the west drainage portion will be treated in this swale before is diverted to the Southcenter detention pond. EROSION AND SEDIMENT CONTROL BMPs A Best Management Practice (BMP) is a physical, structural, and/or managerial practice that prevents or reduces pollution of water. Erosion and sediment control (ESC) BMPs to be used on this project include new straw bale barriers, existing and proposed filter fabric fences, clear plastic covering and stabilized construction entrances/exits. The existing erosion and sediment control BMPs have been constructed recently on the median ditch, under the Interstate 5, Pierce Co. Line to Tukwila, Interim HOV Lanes, Stage 2B project, which overlaps with the Interstate 5, Pierce Co. Line to Tukwila, Southbound HOV and 6 CITY OF 'i UKWILA Truck Climbing Lanes Stage 1 project. An inlet protection filter (by ENVIRO - DRAIN), will also be used to prevent sediments and other contaminants from entering storm drainage systems. The stormwater filter is installed in catch basins, filtering out sediments in the top tray. The second tray is filled with absorbent, a natural cellulose fiber that retains up to 7 times its weight in oil. The third filter is filled with activated carbon to neutralize fertilizers and pesticide. Special provision for maintenances and construction details will be provided in the contract. All exposed and unworked soils will be stabilized by jute matting or clear plastic covering according to the following criteria; from October 1 to April 30, no exposed and unworked soils shall remain unstabilized for more than two days, from May 1 to September 30, no exposed and unworked soils shall remain unstabilized for more than seven days. The new straw bale barriers will be entrenched and anchored. The filter fabric fences consist of filter fabric stretched across and attached to supporting posts and entrenched. Both of these BMPs intercept and detain sediment from disturbed areas and decrease the velocity of sheet and channel flows. The filter fabric fences will be constructed prior to the start of clearing, grubbing, grading, or other earth disturbing activities. They will be maintained during the project by cleaning, repair, or other processes as directed by the WSDOT construction Project Inspector. These temporary erosion and sediment control measures will be removed within 30 days after final site stabilization is achieved or after the temporary BMPs are no longer needed. Disturbed soil areas resulting from removal shall be dressed and permanently stabilized. The stabilized construction entrance consists of a stabilized pad of quarry spalls and mud pallative at construction entrance and exit locations for retaining walls marked "construction access areas" in the retaining wall portion of the site preparation plans. The contractor will be permitted to construct one entrance and exit road in each "construction access area" In addition, a street sweeper will be used. This measure will reduce the amount of mud and dirt transported onto the road which in turn will prevent the sediment from entering storm water runoff elsewhere. The stabilized entrance will be removed within 30 days after final site stabilization is achieved or after the temporary BMP is no longer needed. The construction sequence will be as follows: placing temporary erosion and sediment control BMPs, clearing and grubbing, retaining wall construction, grading, installing the drainage system, completing roadway work, providing permanent erosion stabilization measures, and removing temporary erosion and sediment control BMPs. PERMANENT STABILIZATION Permanent stabilization BMPs to be used on the project include seeding and planting and pipe outlet protection. In addition, the existing rock check dams located in steep median ditches will be utilized to reduce water velocity and erosion and to provide retention of sediments. Disturbed areas throughout the project will be planted with grass or shrubs to prevent soil erosion from wind and water. Unless otherwise approved by the Engineer, seeding, fertilizing and mulching will be performed from March 1 to May 15 and August 15 to October 1. MAINTENANCE Temporary: Straw bale barriers shall be inspected immediately after each runoff - producing rainfall and daily during prolonged rainfall. Necessary repairs shall be accomplished promptly. Sediment deposits shall be CITY OF 11/1(101-A 7 1I/;r ,l L3 6Ju.j. pEfiMlr CENTER removed when the level of deposition reaches approximately one -half the height of the barrier. Any sediment deposits remaining in place after the straw bale barrier is no longer required shall be dressed to conform with the existing grade, prepared, and seeded. Filter fabric fences shall be inspected immediately after each runoff- producing rainfall and daily during prolonged rainfall. Necessary repairs shall be accomplished promptly. Sediment deposits shall be removed when the level of deposition reaches approximately one -third the height of the fence. Any sediment deposits remaining in place after the filter fence is no longer required shall be dressed to conform with the existing grade, prepared, and seeded. The existing rock check dams shall be monitored for performance and sediment accumulation after each runoff - producing rainfall and daily during prolonged rainfall. Sediments shall be removed when it reaches one -half the sump depth. Permanent: See section for the permanent stabilization requirements.

I would like to give you a brief badcground of the NE 124th project We have been working with Alpha Engineering on providing landscape design services on this road widening project. The project is located between SR202 (Woodenville Redmond Road) to NE 132nd and is approximately 1.5 miles long of which .5 miles requires the construction of maximum 28 foot tall retaining walls. We were asked by Alpha Engineering to come up with an inexpensive retaining wall system that would be relatively low maintenance yet add visual interest and diversity to a relatively long and tall wall. The solution we came up with utilized precast 5' x 5' concrete . in a cruxifix form that interlocked. (See attached catalog cut). We found that these panels allowed us to to create large pockets fo lralantings. The size of the panels gave us the human scale the wall needed. We also took the shape of the precast panels and created a custom precast wall planter to hel rep.kpk up the large expanse of wall. (See attached detail). Since there is_m, irrigation for this project, the planters would be watered wildrainage seeping through the wall at cavities located above each planter. In discussing the project with the Reinforced Earth Company, they came up with an estimated cost of 830 per s.f. of wall face. The wall planters were approximately 8600 apiece. Thank you for your time and consideration. If you have any questions, please call me. Sincerely, Ed Mah elIC.
