Construction of the last two trailers is nearing completion and occupation is expected in the next few weeks. Our first occupants moved in on April 17, 2000 due to some unforeseeable construction delays. Design for the new office facility for the County Surveyors was initiated this year but will not be complete until 2001 due to budget shortfalls. This will result in a need to extend the Temporary Use Permit another year, as construction of the new facility is not expected to be complete until 2002. Please let me know if this is possible. Since we have not been in the temporary trailers for most of the first year of the Temporary Use, I would hope that this could be accomplished easily. However if we do have to go through another complete application process, I would like to start well before the expected expiration date on the Temporary Permit extension. Thank you for your attention to this matter. If you have any questions or require more information, please contact me at 206-296-8148.

Currently, we have no records for rare plants or high quality ecosystems in the vicinity of your project. For more information, I have enclosed a list of rare plant species known to occur in the county in which your project is located. The information provided by the Washington Natural Heritage Program is based solely on existing information in the database. In the absence of field inventories, we cannot state whether or not a given site contains high quality ecosystems or rare species; there may be significant natural features in your study area of which we are not aware. The Washington Natural Heritage Program is responsible for information on the state's endangered, threatened, and sensitive plants as well as high quality ecosystems. We have begun to add information on selected groups of animals of conservation concern, such as freshwater mussels, butterflies, salamanders and bats,to our database. We now make this information available in our reports along with information on rare plants and high quality ecosystems. The authority for protection of animal species in Washington rests with the Department of Fish and Wildlife which manages and interprets data on wildlife species of concern in the state. To ensure that you receive information on all animal species of concern, please contact Priority Habitats and Species, Washington Department of Fish and Wildlife, 600 Capitol Way N, Olympia, WA 98501-1091, or by phone (360) 902-2543.

BACKGROUND ERC MEETING DATE May 25, 1999 Project Name King County Temporary Office Trailers Appli-ant King County Department of Transportation File (`!umber LUA-099-044,ECF,TP Project Manager Lesley Nishihira Project Description The applicant, King County Department of Transportation, is requesting approval for the temporary location of six structures totaling 5,860 square feet in area and an associated 21,000 square foot gravel parking area. The structures—two 1,440 sf trailers, two 840 sf trailers, one 900 sf trailer, and one 400 sf storage container—will temporarily house King County Survey crews and equipment. Included with the proposal is the installation of utilities for the trailers and parking stalls for 59 vehicles. The site is relatively flat and is vegetated with brush and small alder and maple trees. The project will require the clearing of the site, including the removal of 3 Douglas-fir trees (two 12", one 5" in caliper). Approximately 500 cubic yards of crushed rock will be brought on-site for the proposed parking area and less than 1,000 cubic yards of material will be moved or placed on site. Drainage for the site will be routed to a bioswale and onsite infiltration pond. The temporary structures will be removed after the completion of a permanent office facility adjacent to the subject site. After the trailers are removed, the site will be converted to a construction material storage yard. The project requires the approval of a Temporary Use Permit which will grant the proposal for 1 year. Upon written request, a single 1 year extension may be granted.

A Fire Mitigation Fee, based on $0.52 per square foot of structure, applies to all develo)ment in the City. The applicant shall pay the applicable Fire Mitigation Fee at a rate of$0.52 per square foot of structure located on the site. The mitigation fee, estimated at $3,047.20, is payable prior to the issuance of building permit:,. The property will be credited for the mitigation fees paid for this proposal when the permanent facility is constri cted. The pr)ject is also required to provide a secondary access to the site pursuant to City code requirements. This will require the creation of a paved access way connecting the west side of the site to 2nu Avenue NE. In addition, the gravel drive proposed does not meet minimum Fire access requirements. As a Condition of Approval for the Tempc rary Use Permit, the applicant will be required to submit revised plans indicating the location and dimensions of the acc ess way as well as the paving of all access roads. Mitigation Measures: The applicant shall pay the applicable Fire Mitigation Fee at a rate of$0.52 per square foot of structure located on the site. The mitigation fee is payable prior to the issuance of building permits. Policy Nexus: Environmental Ordinance (SEPA), Fire Mitigation Fee Resolution and adopting ordinance. 2. Aauifer Protection Area Impacts: The subject site is located within Zone 2 of the Aquifer Protection Area (APA). The temporary use of the site by vehicles for access and parking could pose a potential impact to the aquifer. The Renton Municipal Code requires access and parking areas for sites developed within the APA to be paved. Specific design standards are also required for drainage systems installed in this area. The proposed gravel access and parking area, as well as the bioswale and on-site infiltration pond, do not satisfy minimum requirements for development in the APA. As Conditions of Approval for the Temporary Use Permit, the applicant will be required to revise plans to include minimum design standards for the drainage facility and the paving of the site. In addition, the applicant will be required to obtain construction and building permits. Mitigaion Measures: No further mitigation above and beyond existing code requirements is recommended.

TELEPHONE NUMBER: ( ) atq(,- gl yg N© PROJECT NARRATIVE TEMPORARY OFFICE TRAILERS INTRODUCTION The Roads and Engineering Division of King County Department of Transportation is proposing to relocate two—24' x 60' trailers,two— 14' x 60' trailers,one-20' x 45' trailer, and one- 10' x 40' storage container onto a site at the existing King County Consolidated and Office Repair Facility(CORF) located at 155 Monroe Avenue Northeast in the City of Renton. The proposed trailers will be used to temporarily house King County Survey crews and equipment until a permanent building can be built at this site. This project will also include the addition of approximately 59 parking stalls and all necessary utility hook ups. II. SITE HISTORY King County has owned the CORF facility since July 19, 1951. The site currently houses over 250 employees. This site is in use by King County's Road Maintenance Administration and Special Operation crews,Traffic Engineering, Soils Lab,Parks, and Fleet. The site is presently zoned IL(P). This project under current zoning codes is a permitted use. The site conforms to the 1990 CORF Master Plan. III. SCOPE OF PROPOSED PROJECT-GENERAL The site for the proposed temporary trailers will be located in the northeast quarter Section 16, Township 23,Range 5, due south of the district court buildings. The trailers will be removed after the design and construction of a permanent facility at the CORF site(not to exceed two years). This project will also entail the addition of approximately 59 parking stalls and utility installation for the trailers. The proposed site has a slope differential of not more than 1%, and is currently zoned IL(P). The estimated construction cost is • approximately$100,000. The overall nature and design of the proposed trailers does not significantly alter the current site. The vegetation in the area consists primarily of brush species with a few small trees. The project will increase the number of employees at the CORF site by 27. The proposed site will add 5,800 square feet of office space. The additional vehicles will be accommodated in a 21,000 square foot gravel parking area constructed adjacent to the proposed trailers. Drainage for the proposed site will be routed to a bioswale and onsite infiltration ekN#`NG � MaR 1 v�Q City of Renton Temporary Use Permit is a requirement of this project. Soil test pits showed medium dense sand and gravel for 2' followed by 4.5' of glacial outwash. IV. PROJECT DETAILS-SPECIFIC County forces will install the temporary trailers,parking lot, and utility hook ups. The two 24' x 60' trailers will be used as crew assembly rooms. The two— 14' x 60' trailers and 20' x 45' trailer will be used as offices and equipment storage. The container unit is for equipment storage only. Parking stalls will be used for County vehicles as well as private vehicles. There are an adequate number of parking stalls at this facility. The project construction design includes handicap access ramps for each of the trailers. Sewer,water, electrical, and communications will serve the trailers. Sewer and water permits will be obtained through the City of Renton. V. SUMMARY/CLOSING The proposed installation of the temporary trailers will cause minimal impact to the King County maintenance facility and the surrounding area. Measures have been taken in the proposed design to route drainage to the water quality facility in order to protect both the area's aquifer and to prevent potential leaching of contaminated storm water into area soils. • E5 • 9 T23N R5E W 1/2 E5 . 9 T23N l E 1/2 • _ci 4_� R=et� ) —'6- , _ I . • . —] P S _-- CS p I NE 4th St. —i-arra_i too.

PROJECT OVERVIEW The Roads and Engineering Division of King county Public Works Department is proposing to construct a temporary material storage and sorting pad facility, construct a thirty-six stall parking lot south of the proposed temporary storage pad at the King county Consolidated Office and Repair Facility (CORF) , located at 155 Monroe Avenue Northeast Renton, Washington. The parking lot will contain thirty-six parking stalls, which were lost during CORF Phase I construction. The proposed temporary material storage and sorting pad facility will be a mutually used structure for both King County and the City of Renton forces . The proposed pad will replace the mining and stcckpiling site that was used by County forces from 1949 to March 4 , 1991 . The proposed facility will be used to dry waste material removed frcm enclosed drainage systems by the use of a vacuum-flush truck ( "vactor" ) . Liquids removed from enclosed drainage systems will be decanted into the sanitary sewer system at the existing vactor liquid decant station. Other material to be stored on the pad, will include concrete asphalt and soils collected from routine roadside maintenance activities . The construction of the storm drainage system for the material storage pad will be completed as part of this project . A Frop-T Oil Water Separator, biofiltration swale, a sand filter, and a infiltration pond will be constructed to treat the storm water runoff from the material storage pad' s apron and the proposed parking lot. The systems are sized to convey and treat the entire CORF site which will be addressed in CORF Phase II . Existing On-Site Drainage Features The proposed temporary material storage pad and parking lot site is located 50 feet south of the existing CORF Building "K" and "L" . The area is currently undeveloped. The designs were based on Everett Gravelly Sandy Loam (EVC) soils . No off-site flows affect the existing site drainage. Proposed On-Site Drainage Features The increase in the amount of developmental area is the result of the asphalt apron surrounding the storage pad, road, and rep _acement parking lost during the CORF Phase I Master Plan. Runoff from these areas will be collected in catch basins and conveyed to an oil water separator where it will be treated by a biofiltration swale, a sand filter, and then flows into an infiltration pond. The proposed vehicular apron ' s drainage system as yell as the storm water treatment systems have been KI:1G COUNTY TEMPORARY MATERIAL STORAGE PAD DRAINAGE REPORT 5 . A 40 mil polyethylene liner is proposed beneath the building, the biofiltration swale and sand filter. These facilities are necessary to treat stormwater runoff before it is infiltrated. 6 . A Fop-T oil water separator for the storage pad apron, parking lot, and road is proposed prior to discharge into the biofiltration swale. 7 . There are no Closed Depressions at this project site. 8 . No lakes , wetlands, or closed depressions at this project site . 9 .

GV, I:itAL As rea•rttcd, a toll and foundation engineering study was conducted on the site of the propote.1 additions to the King County Department of Public Works Consolidated Office p4 and lit;air Facility. Figure 1, the Project Location Map, shows the project site. Figures 2, 3 gild 4 preterit the Site Plan Map, the Main Complex Site Plan, and the Parks Department i Yard $lit Plan, respectively. i . tN'e •Rdi rttand that the facility will be expanded in phases. The current phase consists of etpaatl,ynt to the main complex (see Figure 3). These expansions include the construction of *.ttdiai, D, ari increase in floor space for Building J, and a ministorage building. We assume 0_ that thi to additions will be designed as slab-on-grade structures without basements, similar t• the present buildings on the site. Feints plant Include the construction of new parking areas in the Parks Department Yard A area, and a new, large office complex in the presently undeveloped southeast portion of the 11EE��r property. The Investigation activities undertaken as part of this study in regards to the to.thsatt portion of the property are of a reconnaissance nature only. A complete geotech- Rica! IR.estlgation of the subsoils should be undertaken as part of the final design effort d•rtat i hat phase of site expansion. I The tsr.tces of Hong Consulting Engineers, Inc., were retained to conduct geotechnical in- •sttlgatloas which will be germane to the current and to future site development plans. i 1.: Pc; POSE The purpose of the geotechnical investigation is to: a) determine the subsurface soil conditions of the building site b) anal' ze the foundation support for the proposed buildings a 4. 1 _ C Sox 506. lunnw000. Wosninoton P8046 • (206) 743-4774 ben (Thorsen, R.M., 1981, Isostatic Effects of the Last Glaciation in the Puget Lowland, Washington: U.S.G.S Open-File Report 81-370) describes the outwash deposit as the Renton 'elta. The delta sediments were deposited in glacial Lake Russell by the Cedar River. It is elieved by Thorsen that the delta was built against the retreating ice front (p. 44). Oc- ;ional finer grained beds or layers may therefore be expected, within a thick general eposit of sand and gravel. .s.2.2 Soil Exploration Program 'welve test sits were excavated, utilizing a tire mounted Case extend-a-hoe backhoe. The .est pit locations are shown on Figures 2, 3 and 4. The soils uncovered by the excavations were logged by a geologist of Hong Consulting Engineers, Inc. The detailed soil logs for the est pits are presented in Figures 5 through 16. Representative samples of the soils encountered in the test pits were collected and ransported o the laboratory for further testing. infiltration tests were conducted in TP-11 and TP-12, at the request of the client. A corn- nlete explanation of the test methods and the test results are presented in Section 3.4. .j.2.3.1 The Yarn Complex Area Elie main complex area was filled prior to the construction of the present buildings. In the andscaped portions, the surface is underlain by a thin layer of imported sod and topsoil, up to a foot dee p. consisting of sand and gravel, probably borrowed from on site, has been placed over the area. TI e fill varies from 1.5 feet thick, in TP-2, to 3.5 feet thick in TP-6. Below the ►andscaped !.ections, the fill is medium dense to dense. In the shop portions of the main omplex, the fill is very densely compacted, to bear the weight of heavy equipment. No ecords were discovered of the origin or placement of this, or any of the fill found in other portions of the site. The material appears to be equivalent to pit run sand and gravel, and we assume that it was derived from on site. A thin, discontinuous "burned zone" layer underlies the fill in TP-1, TP-3; TP-6, and TP-7. The "burned zone" contains dark gray charcoal, as though the site was burned over to clear it, prior to filling. The burned zone consists of stringers at the top of a thicker unit consist- ing of brown sand and gravel, with a trace of silt developed through soil processes. The burned zone is at most a few inches thick. The brown sand can be as much as one foot thick. Dense, red hrown weathered glacial outwash is found beneath the fIll, burned zones and/or brown sand in TP-1, TP-6, TP-7 and TP-12. The grain composition varies from sand and gravel to sandy gravel. Cobbles are usually common. The weathered zone grades downward into brown ;ray to gray unweathered material of similar composition. 3.2.3.2 The ?arks Department Yard The Parks Department Yard is also underlain by brown fill, of gravelly sand to sandy gravel composition, densified by vehicular traffic. The fill is 2.0 and 2.5 feet deep in TP-4 and TP-5, respectively. The fill is underlain by medium dense to dense, brown to brown gray glacial outwash. The grain size is sandy gravel. 3 3.2.3.3 The Southeast Portion of the Site Fill was found in TP-8 and TP-10. The thickness of the fill was insignificant in TP-8, only 0.5 foot Jeep. However, the fill was found to be 2.5 feet deep in TP-10. Weathered outwash was found in all test pits in this area. The soil consists of medium dense, red brown silty fine sand in TP-9 and TP-10, and sand and gravel in TP-8. Cedar wood debris was observed at the top of the weathered zone in TP-8 and TP-10. The weathered zone is 2.0 feet thicky', in TP-8 to 3.5 feet thick in TP-10. Dense brown gray sand and gravel are found at depth in all the test pits. 3.2.4 Groundwater Conditions The test pits encountered no seepage or other signs of groundwater. Water is present some 30 to 40 feet below surface level, in the bottom of the gravel pit to the north of the main complex. However, this is not necessarily indicative of the level of the water table. Other factors, such as when a hole bottom is disturbed and siltation effectively blocks drainage, may deti rmine the occurrence of ponding in gravel terrain. 3.3 LABORATORY TESTS Moisture tests were run on the representative soil samples, in accordance with ASTM D 2216. The results of these tests are shown on the appropriate soil logs. Grain si :e analyses were accomplished on soil samples from the two infiltration test pits, on the basis of ASTM D 422. The results of theses tests are found in Figures 17 and 18. 3.4 INFILTRATION TEST RESULTS As indicated above, infiltration tests were conducted in TP-11 and TP-12. The test pits were first dug to an average depth of 5 feet. Water was introduced into the test pits by means o` the front loader bucket of the backhoe tractor. The infiltration rates thus re- corded which are presented in Table 1, were much lower than expected. We felt that this was due to the initial test being conducted within the zone of weathered outwash, which contains a significant amount of silt. After consideration of the initial results, it was decided to deepen the pits and conduct a second test. • TABLE 1 Results of Infiltration Tests for Dry Well Design 1 est Depth Material Infiltration F it of Test Rate TP-11 5' Weathered outwash/outwash 5.00 min/inch 1P-12 5' Weathered outwash/outwash 6.88 min/inch TP-12 8' Glacial outwash 0.27 min/inch TP-12 8' Glacial outwash 0.26 min/inch The pit! were duly reopened on 4/25/88, and dug to a depth of 8 feet. On this occasion, water was introduced to the pit bottom by means of a garden hose attached to a domestic tap. Care was taken not to unduly disturb the soils lining the pits. The soils were allowed to saturate for at least one hour prior to commencing the infiltration test. In both of these second tests, the infiltration rates were much higher those of the initial tests. 4 4.1.4 Flo3r Support Considerations Due to the general quality of the fill materials used on this site, we are disinclined to recommend that the owner remove the fill from within the building footprint. We feel the floor slabs may be poured directly on the existing fill sand and gravel, after stripping and removal of the topsoil. We recommend that, at the time of initiation of earthwork, we be called upon to conduct a review of the fill soils within the construction site. Also, the foun- dation and other excavations should be monitored during construction, to be certain no sub- stantial organic soils are unexpectedly present beneath the floor slab areas. If such organic soils are found, the fill materials and organic soil should be overexcavated and rem 3ved. This removal will occasion further expenses, and we recommend that a con- tingency fund be set aside to cover this possibiIIty. After overexcavation, the native, weathered soils should be proof-rolled to give a dense construction surface. A structural fill should be constructed from clean, on-site materials, as indicated Section 4.6. Six inches of freely d-aining gravel or sand and gravel with less than 2% fines should be placed under the slab;. In building which require dry floor conditions at all time, a sheet of Visqueen should be placed over the gravel layer. The thic kness of the concrete slabs should be determined on the basis of the axle loads of the anti:ipated vehicles, the flexural strength of the concrete, and a modulus of subgrade reaction Assuming that the subgrade soils are well compacted, we recommend that a modulus of subgrade of 100 pounds per cubic inch be used to design slab structures which are expected to support heavy vehicles. 4.2 UTI:.ITY CONSTRUCTION PARAMETERS Utilities may be supported on the native soils. Care should be taken not to disturb the utility foundation soils. Soils at the bottom of the trenches should be compacted as indi- cated in Section 4.6. If cobbles or boulders are encountered at the grade level of the utility, the coarse material should be overexcavated, and the cavity filled with compacted sand and gravel. kt least 6 inches of minus 1.5 inch bedding material should be placed beneath all utility pipes. Utility trenches should be backfilled with 1.5 inch minus sand and gravel, im- ported cr borrowed from on site, and compacted as indicated in Section 4.6. 4.3 SETTLEMENT EVALUATION Where the organic materials have been properly removed, and the foundations have been constructed in accordance with the design parameters presented above, the buildings will exhibit tolerable settlement under all live and dead load conditions. 4.4 BOI,ROW SOURCE FOR CONSTRUCTION MATERIALS The on-site soils are suitable for use as structural fill material. 4.5 DR" WELL PARAMETERS Our infiltration tests Indicate that the well should be placed below the weathered zone, as fines cc ntained in the weathered zone inhibit infiltration. We recommend that the well be sunk to at least 8 feet, and that a percolation rate of between 2.5 and 5 minutes per inch be used in the design of the wells. This value is 1/10 to 1/20 the measured infiltration rate. Experience has shown that dry well systems may clog with fines over time. A design safety factor of 10% or less should ensure the long term viability of the dry well system. 6 r...„„ I=- Ser :/1 �.'Y • _ mow..'-l.�r-- .i' I „...a.

The sand filters should be inspected at least once every three months for the first one year. Based on the Inspection findings, the frequency of Inspection may be reduced to once every six months. During an inspection the following minimum features of a sand filter should be monitored: c Accumulation of debris, grit, oil & grease, and other debris on top of the filter and in the pre-treatment BMP. c Clogging of the sand filter. In the event of clogging, water will flow through the over-flow pipe and draw-down of water will take longer than the designed draw-down time. Frequent flow through the over-flow structure Indicates clogging of sand filter or the drainage pipe. c Wears and tears on the geotextile fabric. c Erosion of the sand filter. c Flow channelization on the sand filter indicates Improper function of the flow spreader. Check for accumulation of debris on the flow spreader. c Clean-out pipes should be checked to ensure proper drainage through the perforated pipes. c, Frequency of flow through the overflow pipe. If the surface water runoff (during the storms that are smaller than the designed storm) flow through the overflow pipe than that could indicate clogged sand filter bed or design error. Inlet and outlet pipes should be checked for proper drainage. The sand filters should be maintained as needed. The following is a minimum maintenance schedule: s� Remove the deposited sediment when the accumulation exceeds six Inches In the pre-treatment settling basin. o Remove deposited sediment and debris from the sand filter when accumulation exceeds 1/2 inch. For a sub-surface filter, removal of sediment may performed by replacing the old geotextile fabric with new a geotextile fabric of the same specifications. 7 KING COUNTY TEMPORARY MATERIAL STORAGE PAD DRAINAGE REPORT APPENDIX F: INFILTRATION POND CALCULATIONS King County Project 1rxvion'sir i e-A-ri'c+c.J 0 Comp 4 Chk Rev Public Works Date 1`z4 114 Date Date Page I of 2- Page5 I IJ I 1.--1124 TI ON P DA4 D 100 y r - Z4 Vt✓ Q pui z l 2.&'4 Gf S • inhI4-rn hi)n ►' tit, be)Y,c 1 or) /70i I re-pop,1- QVin'x S. i - 3.i- 11/rvl i 11 FA60Dt2 OP ' FETE = Z (per 4ivJM t7t:SIeih./ MAr rJUos t... q .5.4.- I ) = 17•1- ►n/r rt /Z - t.
