OCT 15, 1993 9:35AM P.02 REQUEST FOR QUALIFICATIONS for a FACILITY MASTER PLAN for each of the following Transfer Stations: Bow Lake Transfer Station - 18800 Orillia Road South, Tukwila First NE Transfer Station - 2300 North 165th Street, Seattle SECTION 1 - Purpose of Request for Qualifications (RFQ) The purpose of this RFQ is to obtain a qualified consultant or consultants to provide engineering services to develop a Facility Master Plan (FMP) for each of two transfer stations, Bow Lake and First NE. The primary objectives of these FMPs are to: 1. Analyze existing site facilities and assess their ability to meet future needs 2. Plan for integration of a pre-load compaction system 3. Plan for integration of expanded recycling and yard waste collection 4. Create a plan from alternative development strategies that will outline a schedule for future site development and can be used for budget level planning. This should include descriptions of future project work scopes and preliminary cost estimates. A major focus of the work needs to be to recommend to.us feasible development alternatives for these sites. What can and should we do there given the physical and demographic constraints of each site. SECTION II - Background Information Bow Lake was constructed in 1977 as a push pit facility. The station is situated on approximately 8 acres. The major structure on site is a 32,000 square foot transfer building, which consists of two separate tipping floors 60 feet and 70 feet in width separated by a surge pit 40 feet in width and 10 feet in.depth. The overall length of the pit is 145 feet and the overall dimension of the tipping floors is 130 feet X 170 feet. The transfer building is open -sided with a 180 feet x 180 feet roof canopy. Since one floor area is wider than the other, the flexibility of utilizing both sides for commercial vehicle tipping has in the past been restricted. This transfer station was constructed on top of a portion of an old landfill and there have been continuous settling problems. Major foundation work to part of the transfer building was done in 1987. The tonnage capacity is rated at 750 tons per day ,(TPD) and the vehicle capacity 900 vehicles per day (VPD). The current weekday average is 550 TPD with a peak of 750 TPD. FROM:KING COUNTY SOLID WA5FF TO: Request for Qualifications June 3, 1993 Page Two 206 433 1833 rte' OCT 15, 1993 9:36AM P.03 First NE is one of five other County -owned transfer stations constructed in the mid- 1960's which all incorporate the same basic plan. First NE is a direct load facility and was not designed to accommodate the larger commercial packer vehicles in use today. The floor is substandard in width and the ceiling height too low to handle these vehicle types. This transfer station was also constructed on top of a portion of an old landfill. The tonnage capacity is rated at 350 TPD and the vehicle capacity 390 VPD. The current weekday average is 285 TPD with a peak of 480 TPD. Loads received at both of these sites are consolidated into transfer trailers and hauled to the County's regional landfill at Cedar Hills for final disposal. Useful life of these transfer stations depends on a number of factors, which include the remaining capacity at Cedar Hills, success of attaining waste reduction and recycling goals, .and the decision to implement waste export (long haul to out -of- county disposal facilities). The Draft 1992 Comprehensive Solid Waste Management Plan recommends that all new and upgraded transfer stations collect primary recyclables (glass, paper, cans) and yard waste. Secondary recyclables such as scrap metal, clean wood, appliances, and SPI -coded plastics 3 -7 would also be collected as needed after private sector options are evaluated. Today's role of the transfer stations has changed from when they were constructed. The basic function of receiving and transferring waste remains the same but the need to modernize operations and implement new programs such as expanded recyclables collection has necessitated that facility master plans 1992.

FROM:KING COUNTY SOLID U TO: Request for Qualifications June 3, 1993 Page Three 206 433 1833 OCT 15, 1993 9:36AM P.04 Existing facilities at the sites Existing facilities include a transfer building, crew quarters, cashier booth, scaling facilities, loaded and empty trailer parking, recycling area, site roadways, and utilities. Both sites are open 7 days a week from 8:OOam to 5:30pm and are staffed by County employees. The main function at both of these sites is to receive many smaller loads of waste and consolidate them into fewer, larger transfer loads. At Bow Lake, customers dump their loads into a, pit, where a dozer breaks down waste before loading it into a transfer trailer. A stationary compactor then compacts loads directly in the trailer. At First NE, customers dump directly into a transfer trailer and a stationary compactor spreads and compacts the load in the trailer. Known problems include not achieving maximum payloads, exceeding allowable trailer axle weights, and rapid wear of transfer trailers due to loading techniques. At both sites, a designated parking area is set aside for the loaded and empty transfer trailers. Site attendants operating a yard tractor pull full trailers from under the transfer building and park them in the full trailer parking area, where the trailers wait for a tractor to haul them to Cedar Hills. Tractors from Cedar Hills bring empty trailers that are staged in the empty trailer parking area, then haul full trailers back to Cedar Hills. The yard tractor pulls an empty trailer from the empty trailer parking area and returns it back under the transfer building. Known problems with this operation include: * insufficient turning radius for new, longer trailers. * liquids leaking from full trailers in the parking area which must then be collected and sent to the sanitary sewer system. * double- handling of trailers at the transfer stations. * dependence on empty trailers always being available to load at the transfer stations. * settlement in the parking areas. Two scales are located next to the cashier's booth at both sites. Vehicles are weighed entering and leaving the facility to determine how much waste was deposited and amount of fee assessed. The access roads leading to and from the scales also serve as queuing areas for customer vehicles. These scaling systems are currently pit type scales, but the County has been modifying their system to convert these to above grade platform scales. There are recycling areas at both sites. These areas and their functions were not in the original design of the transfer stations. Existing space and FROM:KING COUNTY SOLID WAS TO: 206 433 1833 Request for Qualifications June 3, 1993 Page Four CT 15, 1993 9 :37AM P.05 design constraints limit the type and capacity of these recycling facilities. These areas need to be enlarged if expanded recycling programs are to be provided. Currently, the recycling areas have bins to collect glass bottles, mixed waste paper, newspapers,, aluminum cans, tin cans, cardboard; and PET /HDPE plastic bottles. Future recycling area design should be able to accommodate both materials collected at no charge and materials (such as yard waste) which will be collected for a fee. SECTION III - Project Description The purpose of the FMPs is to evaluate the optimal use of available and potentially available space for future uses at each transfer station. Analysis of each site should include: Identification and classification of all applicable physical characteristics at each site (such as areas of buried garbage, adjacent land uses, existing homes, streams, wetlands, and slopes). These characteristics shall to be mapped and detailed on as -built condition drawings.

September_10, 1993 ! 1 r ` 1993 Cat 1 The purpose of this letter is to inform you that the King County Solid Waste Division will soon be starting with the development of a facility master plan for the Bow Lake Transfer Station, located northeast of the South 188th Street and Orillia Road South intersection. This master plan will identify and prioritize future facility improvements that will accommodate customer needs for the next 25 years, including potentially an expanded recyclables collection capability and integration of a pre -load compaction system for mixed municipal solid waste. As this facility is located within Tukwila's municipal boundaries, coordination between agencies will be occurring to properly address SEPA, city planning and comprehensive solid waste planning issues. Our schedule calls for completion of the master plan by mid - March, 1994. It would be appreciated if the City could designate a contact person for coordination on these various planning issues. Our assigned project manager is Tom Lew, P.E. (Phone 296 - 4433). Tom will be responsible for day -to -day project coordination and will be the primary contact person for your staff.

W. Beck and Associates 1. The purpose and scope of the Facility Master Plan was reviewed. The possibility of expansion beyond the current site boundaries was discussed. 2. The majority of the site is located within the City's jurisdiction. The zoning map indicates that most of the site is zoned M -1 (Light Manufacturing) which Ms. Fox indicated would permit the transfer station outright. A review of the zoning code following the meeting indicates that this is not correct and that a transfer station is an unclassified use. Unless the existing use and proposed improvements are somehow "grandfathered in ", an unclassified use permit appears to be needed. 3. Regarding the environmental review process that would be needed, it was agreed that the Solid Waste Divison is the appropriate SEPA lead agency, and that a checklist /DNS would be appropriate provided that there are no significant unavoidable adverse impacts with the improvements proposed in the Plan. This needs to be confirmed with the City's Director of Planning. 4. . The north end of the existing site is zoned R -A (Agricultural) and this could be an issue. Jean Garber will draft a letter for the Solid Waste Division asking the City for answers to questions related to size zoning and permitting. • 5. The City is in the process of revising the Comprehensive Plan and the Zoning Code. Adoption of the revised Plan is not likely before the end of 1994 and the revision of the Zoning Code is to follow that. The County has the opportunity to provide imput to the current revisions and requested that they be placed on the mailing list for notification of meetings /call for comments. 6. It was not clear in which jurisdiction the southern end of the site might reside. It appeared to be either in unicorporated King County or in the City of Seatac. If it is in the County an unclassified use permit would have to be obtained from the County for development in that area of the site. Following the meeting, Jean Garber called the City of Kent and determined that the boundary of their potential annexation area under the Growth Management Act would take their city limits north to the City of Tukwila limits. If this annexation proceeds (it was negotiated between Seatac, Tukwila and Kent and has not yet been approved by the County) the south end of the site would be in the City of Kent. The GMA sets no dealines for annexations to occur. 7. Follow -up contacts with the City on these issues will made by Jean Garber. distribution: • attendees Sue Byers Wendy Butcher Charles Conway 14 October 1993 Mr. Karl Hufnagel, P.E. R.W. Beck and Associates Suite 600 2101 Fourth Avenue Seattle, Washington 98121 AD0LPSON ASSOCIATES, INC. RE: Wetlands reconnaissance for the Bow Lake Transfer Station Facility Master Plan, King County Solid Waste Division, Project No. 9380. Dear Karl: Adolfson Associates Inc. was retained to conduct a site reconnaissance of approximately 8 acres (western half) of the 12.5 -acre Bow Lake Transfer Station Facility for wetland habitat. Adjacent property to the south reportedly owned by M.A. Segale Inc. was also included in this site reconnaissance. The Bow Lake Transfer Station Facility is located south of South Center and east of Interstate Route 5, on the crest of the valley wall overlooking the Kent Valley. The eastern half of the transfer station property was not examined during this site visit due to steep slopes (greater than 30 percent) and unsuitability for future development. As per your request, I have prepared this letter outlining the results of our site walk - through and wetlands reconnaissance conducted on 6 October 1993. Three small jurisdictional wetland areas were identified during this reconnaissance (see Figure 1, attached). Each of these would be classified according to the U.S. Fish and Wildlife Service (Cowardin et al. 1979) as palustrine, broad - leaved forested wetlands (PFO1) with a. dominant overstory of red alder (Alnus rubra). No wetland boundaries were delineated during the 6 October site visit, therefore, all areas illustrated in Figure 1 are approximate. Methods Jurisdictional wetlands are defined as "...those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions." (Federal Register, 1980, 1982). On -site wetlands were identified using both the methodology outlined in the Federal Manual for Identifying and Delineating Jurisdictional Wetlands ("1989 Manual "; Federal Interagency Committee for Wetland Delineation, 1989) and the methodology outlined in the U.S. Army Corps of Engineers Wetlands Delineation Manual ("1987 Manual "; Environmental Laboratory, 1987). Both methods involve a triple parameter approach; wetland hydrology, hydric soils and hydrophytic vegetation must all be present to characterize an area as wetland. King County requires use of the 1989 Manual for identification of wetlands within its jurisdiction. The Corps of Engineers requires use of the 1987 Manual for deterimation of wetlands for permitting under Section 404 of the Clean Water Act. Vegetative, soil and hydrologic characteristics were observed in four, 12 -foot radius circular plots placed in typical upland and wetland community types on -site. Dominant vegetation was recorded in each plot; plots with over 50 percent of the dominant plant species listed as Environmental Analysis 5309 Shilshole Ave. NW, Seattle, WA 98107 Phone(206)789 -9658 Fax(206)789 -9684 iA Hufnagel 14 October 1993 Page 2 "facultative" or wetter were considered to be plots containing hydrophytic vegetation (Reed 1988). (Facultative [FAC] wetland plants are identified as those plant species that have an estimated 34 to 66 percent probability of occurring in a wetland habitat. Plants typically observed . in "wetter" environments are termed "facultative wetland" [FACW] or "obligate" [OBL] and are estimated to occur in wetlands more than 67 percent of the time). Soils were examined for hydric characteristics including dark soil colors (low soil chroma), the presence of bright mottles or gleying and high organic content. Wetland hydrology indicators (i.e., the presence of saturated soils within 18 inches from the soil surface, inundated areas or flowing water) were also recorded. Results Two small wetland drainages were identified within the western half of the Bow Lake Transfer Station Facility property. In addition, one larger wetland drainage was identified on the Segale property to the south (see Figure 1). In each of these areas, vegetation, soils and hydrology parameters met wetland criteria outlined in both the 1987 and 1989 Manuals. Each of the three wetlands appears to be a result of surface water runoff which has been directed away from Interstate 5 and the transfer station. Concrete culvert pipes (approximately 8 to 12 -inch diameter) outfall into each of the three wetlands. Culverts draining to the two wetlands on the transfer station property appear to have been placed during construction of the facility in 1977. Placement of the culvert directing water to the larger wetland drainage to the south appears to predate the transfer station. This culvert drains an undetermined area adjacent to. Interstate 5. Flowing water and seepage was observed in each of the wetlands during the 6 October site visit (see Data Plots 2 and 4, sheets attached). Minor channelization and scouring were noted in each wetland area. The three identified wetlands are forested, with red alder, big -leaf maple (Ater macrophyllum) and an occasional black cottonwood (Populus balsamifera) providing most of the canopy cover. Understory vegetation in the wetlands is primarily pig -a -back plant (Tolmeia mensiezii), mannagrass (Glyceria sp.) and stinging nettle (Urtica diocia). Soils within each wetland were typically saturated to the surface. Wetland soils on -site are gleyed silty sands of a dark greenish gray color (5GY 4/1 in the Munsell Soil Color Chart). Pebbles and cobbles occur on the surface from past flood events. Criteria for hydrophytic vegetation, hydric soils and wetland hydrology are met in each wetland area. Upland deciduous forest located between the three drainages does not meet wetland criteria for vegetation, soils or hydrology (see Data Plots 1 and 3). Alder and big -leaf maple provide the primary overstory cover. Trailing blackberry (Rubus vitifolius), red elderberry (Sambucus racemosa) and stinging nettle are the dominant understory species. Soils tested in upland areas within the transfer station site are typical Alderwood .gravelly loams (as mapped by the Soil Conservation Service) intermixed with a non - native sandy fill. The sandy fill material appears to have been used to cap the landfill upon which the Bow Lake Transfer Station was originally constructed. Refuse (i.e., glass, plastic) was noted to be intermixed in the soils sampled • throughout the transfer station property. Upland areas on the Segale property to the south were typical Alderwood loams of a dark yellowish brown (1OYR 4/4). All soils sampled in upland areas were dry and lacked mottling or gleying. No evidence of wetland hydrology (i.e., . watermarks, driftlines, algal mats, inundation) was observed in these areas during the site visit. Hofnagel 14 October 1993 Page 3 Summary & Recommendations King County regulates wetlands within its jurisdiction that have been identified using the 1989 Manual. The Corps of Engineers regulates wetlands identified using the 1987 Manual. Three forested wetland areas were determined and identified using both methods within the Bow Lake . .Transfer Station project area and a portion of the Segale property extending approximately 300 feet to the south (Figure 1). Wetland habitat was not identified in any other area within the transfer station facility, most 'ofwhich is developed or landscaped. The identified wetlands are forested and appear to occupy a total acreage of less than one acre, although no formal wetland delineation was conducted to determine exact wetland boundaries. According to the King County Sensitive Areas Ordinance (SAO), wetlands equal to or less than one acre in size that have a forested wetland class are rated "Class 2 ". Class 2 wetlands -are typically afforded a 50 -foot buffer and 15 -foot building setback from development in King County. Regulated Class 2 wetlands must be restored or replaced at an area -based ratio of 2:1, if impacted during development. Mitigation is commonly required to be "in- kind" replacement and must occur on -site. The Corps of Engineers does not typically regulate proposed wetland fills less than one acre in size. For fills greater.than one acre, a Nationwide Permit 26 may be required by the Corps. The Nationwide Permit 26 regulates discharges of dredge or fill material into headwaters or isolated waters, including headwater or isolated wetlands. Regional conditions on the Nationwide 26 state that fill resulting in a loss of wetland area greater. than 2 acres is not authorized; an Individual Permit under Section 404 would therefore be required. In addition, an Individual 401 • y Certification by the State (Department of Ecology) may required for fills more than one acre. • If further investigation is desired, Adolfson Associates Inc. recommends a formal wetland delineation be conducted within the preferred site for•proposed expansion of the Bow Lake Transfer Station. Exact determinations of wetland boundaries are necessary for the design phase of this project to accurately place wetlands in the landscape and to calculate actual wetland area. A professional survey of flagged boundaries would also be recommended at that time. Thank you for contacting us for environmental consulting services. Please call if we can be of further assistance in the permitting process for this project. Sincerely,' .ADOLFSON ASSOCIATES INC. Teresa H.

Engineering Services Manager King County Solid Waste Division Department of Public Works Yesler Building 400 Yesler Way, Room 600 Seattle, WA 98104 -2637 December 29, 1993 RE: Bow Lake Transfer Station -- Facility Master Plan Dear Mr. Kiernan: Rick Beeler, Director This letter is in response to your letter of November 22, 1993 to Rick Beeler in which you raise several issues regarding the Bow Lake Transfer Station facility in Tukwila. I will address your concerns by topic. COMPREHENSIVE PLAN: The Comprehensive Plan update is scheduled to be completed in late '1994 to mid -1995. The area is currently designated "light industrial" by the existing Comprehensive Plan. Prior to staff and Committee recommendation and review in mid -1994, we cannot comment definitively whether or not the designation will change. ZONING CODE: Portions of the area are zoned M- 1(light industrial) and portions are R -A (agricultural). Zoning Code revisions are scheduled for completion approximately one year after the Comprehensive Plan, in late 1995 to mid -1996. A transfer station is neither permitted outright, nor as a conditional or accessory use under the R -A zoning. With the current zoning, expansion of the transfer station will require a rezone. An application is enclosed. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • (206) 431-3670 • Fax (206) 431-3665 _. Ki ernan Ltr. 12/29/93 Page 2 UNCLASSIFIED USE: An unclassified use permit would be required to implement any planned improvements. An application is enclosed. VESTING: The applicant is vested to existing codes and regulations once a complete building permit application, including architectural drawings sufficient to construct the project, is submitted. SENSITIVE AREAS: The site under discussion is subject to the Sensitive Areas requirements. Wetlands: We encourage you to submit preliminary site and improvement plan information through our Pre - application process at your earliest convenience. At that point Gary Schulz, our staff Urban Environmentalist, could review your plans and discuss appropriate mitigation with you. Geologic Instability: We will need a preliminary plan to be able to make comments on this issue. TREE REGULATIONS: Since development may occur within a sensitive area, the project is subject to Tree Regulations (TMC 18.54). POTENTIAL ISSUES: We cannot comment on the possibility of Comprehensive Plan or Zoning designation changes prior to the time that Committee review occurs. Whether or not any changes actually occur, we do wish to inform you of preliminary staff -level discussion about expanded development regulations for hillside areas, such as the one in the area which you've identified for potential expansion. Clearly, there are several interrelated issues which pertain to proposed improvements to the Bow Lake Transfer Station. Prior to proceeding further, we strongly encourage you to complete the rieriidn LLr. -12/29/93 Page 3 enclosed form for a pre - application, and come in to meet with our staff. In that way we can discuss all the issues in a coordinated manner, as you begin the process of working with the City of Tukwila. Sincerely, t/16 J ck Pace • Senior Planner c ,:c :...4 Rebecea; Enc. King County Solid Waste Division Department of Public Works Yesler Building 400 Tesler Way, Room 600 Seattle, WA 98104 -2637 (206) 296-6542 November 22, 1993 Mr. Rick Beeler Director Department of Community Development City of Tukwila 6300 Southcenter Boulevard, Suite 100 Tukwila, WA 98188 RE: Bow Lake Transfer Station - Facility Master Plan Dear Mr. Beeler: RECEIVED DEC: 199,3 COMMUNITY DEVELOPMENT On October 21, 1993, staff of the King County Solid Waste Division (SWD) and its engineering consultant met with Rebecca Fox of the City of Tukwila's Department of Community Development to discuss the proposed Facility Master Plan for the Bow Lake Transfer Station. We appreciated the opportunity to explain our planning objectives, and to gain an understanding of City policies and requirements relevant to the eventual permitting of facility improvements. The existing transfer station is located northeast of the South 188th Street and Orillia Road South intersection (Figure 1). The purpose of the Facility Master Plan project is to identify and prioritize facility improvements required to accommodate service needs for the next 25 years. Potential improvements include expanded capability for collecting recyclables, and a pre -load compaction system for mixed municipal solid waste. The Facility Master Plan will evaluate a number of different development alternatives. These will include keeping all improvements within the existing boundaries of the facility, and evaluating the alternatives of acquiring property north of the existing site from the Washington Department of Transportation to accommodate placement of the pre -load compaction system, and acquiring land adjacent to, and south of, the site to expand the recycling capability to meet minimum standards specified in the 1992 King County Comprehensive Solid Waste Management Plan. Since the existing site and most of the potential expansion areas lie within the municipal boundaries of the City of Tukwila (Figure 1), it is important that we have a correct and complete understanding of the City's policies and requirements. The purpose of this letter is to review the topics discussed at our meeting with Rebecca Fox; and to identify issues that need to be resolved to allow us to complete our planning effort. Mr. Rick Beeler November 22, 1993 Page Two Environmental Review Environmental review will not take place until SWD is ready to implement planned improvements. Nonetheless, an understanding of the environmental review process is essential to allow us to project the cost and schedule for plan implementation. In accordance with the SEPA Rules (WAC 197 -11 -926), the King County Solid Waste Division will be the lead agency for the environmental review. However, we recognize that the environmental review would also have to satisfy Tukwila's requirements to allow the City to issue necessary permits • and approvals. Therefore, we will coordinate closely with City staff on the form and content of the environmental review. At this time, we believe that an expanded checklist /mitigated DNS may be the appropriate form of environmental review. This is based on the fact that the basic use of the site will not change, and there will be no need for significantly increased transfer station capacity. Nonetheless, there may be an expansion of the footprint of the transfer station, as well as an expansion of the recycling area both on and off -site. We plan to conduct studies to determine the potential significant adverse impacts of these improvements, including studies of traffic, noise, odor, geologic stability, and wetlands. These studies will recommend measures to mitigate identified adverse impacts. Based on study results and consultation with the City and others, the Division will reevaluate the appropriateness of an expanded checklist /DNS. Zoning /Permits Rebecca Fox indicated that the existing facility and proposed expansion area are almost entirely in the M -1 (Light Industry) zone, and that a transfer /recycling station is permitted outright in that zone. She concluded, therefore, that the planned facility improvements would require only a design review and building permits. Since our meeting, we have reviewed the Tukwila Zoning Code and Comprehensive Land Use Policy Plan more thoroughly. Based on the zoning map, most of the existing site is zoned R -A (Agriculture), although the developed portion of the site is primarily in the M -1 zone. However, we question whether a transfer /recycling station is permitted outright in any zone. In fact, Section 18.66.020 of the Zoning Code indicates that "transfer stations (refuse and garbage) when operated by a public agency" require an unclassified use permit. Mr. Rick Beeler November 22, 1993 Page Three Under the Comprehensive Land Use Policy Plan, most of the existing site and potential expansion area is designated Public Facilities or Commercial, with a small portion in the southeast corner of the existing site designated Light Industrial. A transfer /recycling station appears to be consistent with the objectives and policies associated with these designations. However, we understand that a new Comprehensive Plan is currently being developed in response to the Growth Management Act; and that once the new plan is adopted, the Zoning Code will be revised accordingly. • To allow us to understand how site zoning and future comprehensive planning may affect our plans, we would appreciate answers to the following questions: 1. Would the proposed facility improvements be "grandfathered in ", since the basic use of the site would remain unchanged? If not, would an unclassified use permit be required to implement any planned improvements? 2. If an unclassified use permit is required, we would appreciate your sending us a copy of the application form and indicating the approximate time required from submittal of the application to approval of the permit and completion of improvements. 3. What is the schedule for developing and adopting a new Comprehensive Land Use Policy Plan, and revising the Zoning Code ?_ Are the plan designations and zoning for the Bow Lake-Transfer Station site and surrounding area likely to change+p'Wi 11 transfer stations remain an unclassified use in all zonesT 4.

At what point in the environmental review /permitting process are the applicant's rights vested -- in other words, at what point are we assured that the proposed improvements can be implemented under existing regulations even if those regulations change? Wetlands The Division conducted a site reconnaissance for the purpose of determining whether there are wetlands present on the developable portion of the transfer station site (the western half) or the potential expansion area to the south. As shown in the figure in the enclosed reconnaissance report, three small forested wetlands were identified in this area. These wetlands have not yet been delineated, so the boundaries shown are approximate. Each of the three appears to be the result of surface water runoff which has been directed through concrete culverts away from Interstate 5 and the transfer station. Mr. Rick Beeler November 22, 1993 Page Four Although the three wetlands are small, they would apparently be classified as Type 2 wetlands under Section 18.45.020 of the City of Tukwila Zoning Code because they are forested. The easternmost wetland would likely not be impacted by planned facility improvements. However, the two southernmost wetlands lie in the only area where topography would allow expansion of the recycling capacity of the site. No reasonable use could be made of this area unless the wetlands were filled. It appears that the planned facility improvements do not fall within the uses permitted within Type 2 wetlands or wetland buffers, as outlined in Section 18.45.080(a), (b), and (h) of the Zoning Code. However, SWD believes that a reasonable use exception or variance would be appropriate in this case, particularly since the proposed use is an essential public utility. The Division's consultant engineer has indicated that drainage from the concrete culverts, which is the source of water for the wetlands, could be rerouted to the detention pond which may be constructed as part of the planned facility improvements. Wetland mitigation could be incorporated into the constructed drainage channels and /or the detention pond. In your response to this letter, we would appreciate clarification of the City's requirements for permitting filling of Type 2 wetlands, including what might constitute an acceptable mitigation plan. Areas of Potential Geologic Stability As evident in Figure 1 of the wetland report, there are steep slopes in the eastern half and along the western edge of the existing site. In addition, an old landfill underlies the flat portions of the existing site and potential expansion area. As part of SWD's planning process, a geotechnical report will be prepared by a qualified geotechnical consultant pursuant to the requirements of Sections 18.45.060 and 18.45.080(e)(4) of the Zoning Code. Pursuant to Section 18.45.040(d)(1), the geotechnical report will analyze and make recommendations on the need for, and width of any buffers necessary to ensure slope stability. The geotechnical report will also evaluate stability issues associated with construction of facilities over an old landfill. Please let us know if there are any other City requirements that we should keep in mind regarding areas of potential geologic instability. Again, the Division appreciated the opportunity to initiate coordination with the City of Tukwila on the Facility Master Plan for the Bow Lake Transfer Station. We also look forward to the opportunity to be involved in future planning and zoning activities that would affect our facility. Your response to this letter will assist us in proceeding with this important planning effort. Mr. Rick Beeler November 22, 1993 Page Five If you have any questions, please call me at 296 -4419 or.
