Existing zoning adjacent to the subject site is Business Commercial (BC) and Office Park (OP). Proponent: City of Federal Way Department of Public Works 33530 1st Way South Federal Way, WA 98003 (206) 661-4134 Contact: Pearl Kronstad, Project Engineer Department of Public Works 33530 1st Way South Federal Way, WA 98003 (206) 661-4134 Location: South 348th Street between I-5 and 1st Avenue South (Exhibit B). Lead Agency: City of Federal Way. City Contact: Stephen Clifton, AICP - Senior Planner / Urban Designer, 661-4109. 1 The Responsible Official of the City of Federal Way hereby makes the following Findings of Fact based upon impacts identified in the environmental checklist and the "Final Staff Evaluation for Environmental Checklist"; Federal Way application no. SEP94-0014, Conclusions of Law based upon the interim 1990 Federal Way Comprehensive Plan, and other policies, plans, rules, and regulations designated as a basis for exercise of substantive authority under the Washington State Environmental Policy Act Rules pursuant to R.C.W. 43.21C.060. Findings of Fact: 1. The proposal is to extend westbound and establish new eastbound HOV lanes along South 348th Street; interconnect signals to improve signalization; add landscaping to improve arterial aesthetics; construct stormwater facilities to mitigate project impacts; and correct alignments and modify the crest vertical curve of South 348th Street. 2. Existing zoning adjacent to the subject site is Business Commercial (BC) and Office Park (OP). 3. Current uses of the site and surrounding area include the following: Site: Developed Roadway. North: Retail, Commercial, Office and Roadway. South: Retail, Commercial, Truck Stop and Roadway. East: Retail and Commercial, I-5. West: Retail and Commercial, Roadway. 6. Preliminary estimates indicate 4,770 cubic yards of material excavated, 7,160 cubic yards of gravel fill imported. Cuts and fills are necessary for the construction of sidewalks, landscaping, road alignment and storm water drainage facilities. Imported materials will be from local sources. 7. Any erosion -related impacts during clearing and construction will be mitigated by implementing a Temporary Erosion/Sedimentation Control (TESC) plan. 8. As with all paved developed areas, the new asphalt areas will contribute some pollutants to ground and surface waters by means of storm water runoff across the site. Some of these pollutants can be extracted from the runoff by use of grass -lined biofiltration swales. The site will contain a bioswale and detention facility. 9. To control downstream impact of new development, including public and private streets and highways and where storm water detention is required by code, the facilities shall be sized in accordance with recommendation BW-3 of the Executive Proposed Basin Plan, Hylebos Creek and Lower Puget Sound. Condition #1 below addresses this issue. 10. The environment will be improved by adding landscape medians and landscaping along the sides of roadways and sidewalks. New landscaping materials (i.e., plants, trees, and groundcovers) will consist primarily of drought -tolerant species. 11. The Final Staff Evaluation for Environmental Checklist, Federal Way Application No. SEP94-0014 is hereby incorporated by reference as though set forth in full. Conclusions of Law: Federal Way Comprehensive Plan Policies (1990) FWCP Section C-25 - Assure that commercial development has minimal impact on lakes, streams and drainage ways, air quality or noise levels. The lead agency has determined that the proposed action does not have a probable significant adverse impact on the environment, and an Environmental Impact Statement (EIS) is not required under RCW 43.21C.030(2)(c), only if the following conditions are met. This decision was made after review of a completed environmental checklist, site visits, and other information and reports on file with the lead agency. This information is available to the public on request. Conditions: 1. Runoff from the additional impervious surface areas shall be controlled by the use of on -site detention per the King County Surface Design Manual (KCSWDM) and recommendation BW-3 of the Hylebos Creek and Lower Puget Sound Basin Plan unless additional regional detention is developed. Runoff is restricted to 70 % of the pre -developed two-year runoff with storage provided for a 100-year storm event. 30 % factor of safety is not required. This MDNS is issued under WAC 197-11-340(2); the lead agency will not act on this proposal for 15 days from the date of issuance. Comments must be submitted no later than 5 p.m. August 24, 1994.

ENVIRONMENTAL CHECKLIST The following lists the elements of the Environmental Checklist (Exhibit Q. A response to each describes: 1. Whether or not City staff concurs with the applicant's response to the SEPA checklist item, or 2. City Staff's additional comments or clarification to each checklist item. A. BACKGROUND: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. Concur with Checklist. B. ENVIRONMENTAL ELEMENTS: 1. Earth: a, b, c and d. Concur with checklist. e. Topsoil will be required for Landscape Areas f. Concur with checklist. If no measures are taken to ensure that erosion does not take place, erosion could occur on site. Item Lh below describes how the issue of erosion control is to be addressed. g. Concur with checklist. h. Concur with checklist. In addition, Federal Way Comprehensive Plan Policy NE-6 calls for "Enforcement measures to be taken during construction to prevent erosion." Any erosion -related impacts during clearing and construction activities must be performed in accordance with a Temporary Erosion/Sedimentation Control (TESC) plan. No further mitigation is required. 2. Air: a. Concur with checklist. In addition, Short term impacts to air quality will occur during construction and paving operations. C Construction activity, especially site preparation work, will contribute to a short term increase in local suspended particulate levels. Construction activity also contributes to carbon monoxide levels through the operation of construction machinery, the use of trucks to deliver equipment and materials, and worker access to the site by automobile. These activities also involve emissions of hydrocarbons and oxides of nitrogen, potentially elevating the level of photochemical oxidants, such as ozone, in the ambient air. b.

B(1)(g) The checklist indicates that the same amount of impervious surface area will result from the widening of the street. How will this take place? What impervious areas will be removed to compensate for the new areas? B(3)(c)(1) The plans for this project propose to treat runoff from approximately the eastern half of the roadway through a coalescing plate oil/water separator. Runoff from this area then proceeds into the head of the biofiltration swale/detention facility along the roadway. The western portion of the roadway east of Pacific Higway South is to be collected and conveyed directly into the proposed biofiltration swale/detention facility approximately midway along the swale's course without any oil/water separation. The extreme western portion of the site does not propose any oil/water separation or detention. The runoff from this area is conveyed along S. 348th Street westward to the Hylebos wetland area. The plans should be modified to provide coalescing oil/water separation for all areas of the site as a retrofit measure required under the nonconformance section of the Federal Way City Code, 22-330(a)(6), for immediate compliance with water quality standards. This would require an additional separator prior to discharge of the western portion of the site east of Pacific Highway South into the biofiltration swale. In lieu of an additional separator and to achieve better treatment through the swale instead of combining untreated water with partially biofiltered water, the runoff from this area should be routed to the east and the proposed separator at the head of the swale be upsized and utilized. The extreme western portion of the site should also be retrofitted with a coalescing separator in the right-of-way prior to discharging into the hylebos wetlands. Consideration should be given to the orientation of the drainage facilities to allow future by-passing of high flows around the biofiltration swale to the Pacific Highway drainage system and transferring the detention to a future Welter's pond regional site. Can the upstream bypass piping along the south side of S. 348th St. be utilized as a high -flow bypass for the street system around the biofiltration swale? B(5)(c) The site is located in the Pacific Flyway, a significant route for migrating waterfowl. B(7)(b)(2) Night time construction activities will require the written approval from the Director of Community Development per Section 22-1006 of the FWCC. B(7)(b)(3) This section states that a variance from the noise regulations may be required. Will this require Process II per Section 22-196 or will the activities just be equivalent to the usual daytime noise but only the hours of operation are changed therefore only requiring written approval as stated above? B(14)(b) Pierce Transit also serves this area. APPLICATION NO.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. there several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) General A plan view of the proposed project is illustrated in Figures 2-A and 2-B. The main elements of the proposed project consist of the following improvements: + Extend westbound and establish new eastbound HOV lanes within the project limits (with sufficient width to accommodate bicyclists). • Sidewalks on both sides of South 348th Street. • Signal interconnect to improve signal coordination. • Landscaping to improve arterial aesthetics and reinforce the concept of South 348th Street as a "Gateway" to the City of Federal Way. + Stormwater facilities to mitigate project impacts on the Hylebos Drainage Basin. • A horizontal alignment shift near SR-99 to best accommodate the new roadway channelization. • Modification of the crest vertical curve at the South 348th Street/SR-99 intersection. This will eliminate a sight distance problem across SR-99. • The horizontal kink in the South 348th Street alignment will be straightened to reduce the horizontal offset across SR-99. The proposed project elements are the result of analysis conducted for the Predesign Report, direction from City staff, and input from local property owners. The HOV lanes are one of the principal reasons for the project. Regional policies are encouraging the use of 2 transit. Development of HOV lanes on arterial streets is viewed as a means to further enhance the viability of the regional HOV system. Although they are anticipated to have minimal impact on improving the level of congestion in the project corridor for single occupancy vehicles (SOV), the HOV lanes are intended to provide a time advantage to transit vehicles using the corridor. A queue jump is proposed to be included for westbound transit vehicles at the South 348th Street intersection with SR-99. Additional width has been incorporated into the proposed HOV lane to accommodate bicycles and encourage alternative modes of transportation. Sidewalks have been proposed to provide better delineation between pedestrians and vehicles. Vehicular volumes within the corridor are extremely heavy with average week day travel volumes over 36,000 vehicles. Pedestrian activity is constant, although not as heavy as would occur in an urban environment. As a result, eight -foot sidewalks have been proposed for the project. A signal interconnect will be incorporated in order to improve traffic flow within the corridor. The interconnect systems are a relatively inexpensive means to improve the traffic congestion in the area. A key to the proposed aesthetic improvements in the corridor is the desire expressed by the local community that South 348th Street represents a "gateway" to the City of Federal Way. The "gateway" concept for the project is accomplished by incorporating street trees, shrubs and ground cover into the project. The proposed landscaped median would also minimize left -turn opportunities in the corridor. The left - turns are a contributing element to the corridor's traffic congestion. A combined water quality/detention system has been developed for the project which meets the Hylobos Drainage Basin requirements for new projects. The proposed system will not require any additional right-of-way (although some fill on the site of the truck stop's long-term parking lot will be necessary). The proposed water quality/detention facility serves the dual purpose of providing water quality treatment under low flow conditions and detention for the project design storm. The additional fill on the site of the truck stop's long-term parking lot is proposed instead of a wall that would be required to keep project impacts within the right-of-way. The fill will still allow the area to be used for parking while minimizing costs. The proposed horizontal alignment shift near SR-99 will accommodate the new roadway channelization and improve geometrics. The shift is a modification which allows the South 348th Street channelization on the east side of SR-99 to align as best as possible with the channelization on the west side of SR-99. The crest vertical curve on South 348th Street at the SR-99 intersection currently accommodates a design speed of less than 25 mph for stopping sight distance. The proposed improvements will correct this deficiency to meet the project design speed of 40 mph for stopping sight distance. Several alternatives were considered with the proposed profile providing a minimal impact to both the existing SR- 99 profile and properties adjacent to South 348th Street. The proposed roadway profile is illustrated in Figure 3. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project is located within the City of Federal Way in Township 21N, Range 4E, Section 20. The principal area of construction consists of the South 348th Street corridor from SR-161 (also known as 16th Avenue South) and west just beyond SR-99 (a.k.a. Pacific Highway South). In addition, signal interconnect systems are planned along South 348th Street from I-5 to 1st Avenue, and along SR-99 from 356th Street to 336th Street. A left turn signal will also be added on 1st Avenue at 348th Street. A vicinity map and site plan are shown in Figures 1, 2A and 2B. B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site (circle one): Flat, rolling, hilly, steep slopes, mountainous, other b. What is the steepest slope on the site (approximate percent slope) ? Approximately 25 percent along road sideslopes and ditches. 4 c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The Soil Conservation Service Soil Survey for King County (1973) indicates the site area is underlain by Everett- Alderwood Gravelly Sandy Loam and Urban Land (fill). Preliminary site investigations indicate the presence of glacial till. d. Are there surface indications or 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. Minor cut and fill will be required for new sidewalks, landscaping, road alignment and storm water drainage facilities. Stormwater facility improvements include excavation to enlarge ane regrade a water quality swale. Preliminary estimates for the project indicate 4,770 cubic yards of material will be excavated with 7,160 cubic yards of gravel fill imported. Imported landscaping topsoil may also be required. Imported materials will be from local sources. f. Could erosion occur as a result of clearing, construction or use? If so, generally describe. The potential for erosion is low because of the flat slopes in the project area and the minor amount of clearing required. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? Approximately 80 percent of the road right-of-way is covered with asphalt or concrete paving in its existing condition. The same area of imprevious surface will remain as a result of the project. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Erosion control measures will be implemented during construction as appropriate, including clearly marking clearing limits, scheduling construction during the dry 5 season, seeding and mulching exposed soil as soon as possible, and installing filter fabric fences along the downstream edge of construction limits. The erosion control plan will comply with City of Federal Way regulations. Erosion will not be a concern during project operation. 2. Air a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. Construction of the project will result in a temporary increase in dust and construction vehicle emissions. The project's HOV lane and signalization improvements may result in minor improvements to traffic congestion during operation and an associated slight reduction in vehicle emissions. 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 air, if any: During construction activities fugitive dust will be reduced by watering exposed soils during dry conditions, and inactive storage piles will be stabilized with watering, dust suppressants, or covering. 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. No surface water bodies are located within the project boundaries other than constructed roadside drainage ditches. The project site is located in the Hylebos Creek Drainage Basin and the West Branch Hylebos Creek is near the western site boundary and Hylobos wetland is located southwest of the site area. H. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. R" 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. No filling or dredging will occur within surface water or jurisdictional wetlands. 4) Will the proposal require surface water withdrawals or diversions? Give general descriptions, 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. No. 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 ground water? 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 others sources, if any (for example: Domestic sewage; industrial, containing the following chemicals . . .; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. N/A 7 C. d. 4. a. X 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. The proposed stormwater system will have three collection and conveyence systems. Systems 1 and 2 will collect runoff from the road right-of-way and tributary areas in a series of catch basins and convey the runoff through collector pipelines to a combined biofilter and detention channel located on the southeast corner of the intersection of South 348th Street and SR-99 (along the existing ditch). The detention channel/biofilter will consist of a swaled, open, 300-foot channel vegetated with grasses and emergent wetland plants. The channel will discharge to the existing 18-inch diameter storm drain in the east shoulder of SR-99. The stormwater system eventually outfalls at Welter Pond. A coalescing plate oil -water separator will be located upstream of the detention channel/biofilter for conveyence system 1 which collects runoff from the truckstop area and portions of South 348th Street. Conveyence system 3 will collect stormwater from the road right-of-way from between SR-99 to the westerly project limits. This system will also consist of catch basins and collector pipeline discharging to the storm drain in the existing roadway and outfalling to the West Branch Hylebos Creek. Because no significant increase in impervious area is proposed in this area, no retrofit of detention and water quality controls are propsed for this system. 2) Could waste materials enter ground or surface waters? If so, generally describe. Some pollutants carried in the roadway runoff may reach ground and surface waters. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: See 3.c.1). The oil/water separator and biofiltration/detention facilities would decrease the amount of roadway pollutants reaching surface and ground water. Plants Check or circle types of vegetation found on the site: deciduous tree: alder, maple, aspen, other: birch X evergreen tree: fir, cedar, pine, other X shrubs: Himalayan blackberry, salmonberry grass: canarygrass, orchard -grass pasture crop or grain wet soil plants: cattail, skunk cabbage water plants: water lily, eelgrass, milfoil, other other types of vegetation b.
