Bauch, Mayor MEMORANDUM To: FILE #79 -22 -SUB and EPIC -FD -78 FROM: Mark Caughey, Assistant Planner DATE: 30 August 1979 SUBJECT: SYNOPSIS OF MEETING, BEL CREST HEIGHTS PLAT This morning at city hall, representatives of the Bel Crest development met with staff members of the 0.C.D. and Public Works Department regarding constraints upon final approval of the plat as imposed by the Planning Commission at its 26 July 1979 meeting, and as enumerated in the 0.C.D. Director's confirming letter of 1 August 1979. The entire substance of the meeting centered upon roadway improvement obligations for the project's 54th Street frontage. All present seemed to agree that a sidewalk on the west side of 54th Street is desireable for the safety of schoolchildren in the area. Some disagreement exists, however, with the extent to which the developers are responsible for improving 54th Street. All present agreed that the ideal roadway improve- ment would include a full -width street section with curb, gutter and sidewalk on the west edge extending from Slade Way to 166th Street. However, the developers contend that they should be responsible to improve a half- street only for the immediate frontage of their project. To accomplish the intended purpose of this meeting -- facilitating sub- mittal of the final plat to City Council -- the developer agreed to pre- pare graphic material depicting a long term solution for deficiencies of 54th Avenue, but to accompany that material with a position paper stating which improvements they feel obligated to implement. Their presentation will be matched by a position paper prepared by the D.P.W. analyzing what they believe should be provided by the developer and what concomittant improvements should be funded by the City. These two positions will be transmitted to Council along with the final plat to serve as a basis for negotiation and resolution. A corollary aspect of the development to be resolved at the final plat approval stage is the desirability of constructing the internal cul -de -sac street prior to build -out of individual lots.

CON OF TUKWILA JAN l8 1979 In accordance with your request, an engineering geologist from our office visited the subject site on January 12, 1979. The purpose of our visit was to evaluate the soil engineering feasibility of developing the proposed plat includ- ing consideration of the stability of the site soils. The site is located on the west side of 54th Avenue South between 166th Street and Slade Way in Tukwila, Washington. The approximately 4 acre site is situated on an east facing hill slope and a 15 lot subdivision is planned on the property. The site gradually steepens eastward with total relief across the site of about 100 feet. The site is primarily covered with grass, brush, ferns, and small and large trees. From our visual observations of the site and knowledge of local geologic conditions, the near surface site soils appear to be recessional gravels and sand deposits. The recessional deposits are generally underlain by glacial till in this area. We observed the recessional deposits to be in a loose to medium dense condition. Evidence of slope weakness along the east edge of 54th Avenue South and the adjoining slopes above Interstate Highway 5 was noted. It is our understanding that localized instability has occurred in the past on the slopes above Interstate 5 and the slopes have required maintenance. No signs of mass instability were noted on the site, however, we did observe some minor surface slopewash in the lower road cut areas. Groundwater was not noted at the time of our inspection, however, portions of the site soils were frozen and this could result in changes in the future. Surface runoff is controlled by a CMP half section along the west side of the roadway. H and L.Associates January 15, 1979 Page Two E -836 The lack of surface seepage generally indicates that groundwater lies at some depth below the surface. However, considering the geologic history of the area and the conditions underlying the site, it is imperative that adequate surface and subsurface drainage be maintained during and after construction to maintain long term stability of the site. Storm water runoff should be kept in strict control, not permitting pond - ing and assuring a positive gradient at all locations on the property. Uncon- trolled surface runoff should not be permitted on the site or on neighboring slopes. Lined drainage facilities should be provided to convey the surface runoff to the appropriate storm drainage sites. The existing slopes have a natural ground cover and vegetation that protect the slopes from erosion, hence this cover should be allowed to remain wherever possible. Exposed slopes should also be planted with an adequate ground cover to minimize erosion. All downspouts should be connected to yard drainage lines which are tight -lined away from the building areas. The intent is that yard drainage from improved building lots over the top of slopes would not be greater in volume or velocity than exists presently in the natural state unless miti- gated by storm drainage improvements. In summary, based on our evaluation, we feel the site is developable from a soil engineering standpoint. The primary features to be considered in dev- elopment are control of surface and subsurface water. General procedures for surface runoff control were discussed herein, however, delineation of approp- riate subsurface control measures will require drilling of deep borings. These will establish the.actual depth of water, permit future monitoring and also establish a geologic profile of the site and the related stability aspects. We trust this preliminary information is adequate for your requirements. Should you need additional information or clarification, please call. Respectfully submitted, ARTH CONSULTANTS, INC.

Bauch, Mayor 6 December 1978 Mr. Chan Chow Stepan & Associates, Inc. 32123 First Ave. So. Federal Way, WA 98002 RE: Bel Crest Heights - Preliminary Plat Dear Mr. Chow: The preliminary plat application and environmental checklist for "Bel Crest Heights" have been tentatively reviewed and found to have two major points of concern. The first is the possibility of development of adjacent properties. The proposal does not provide a means of access for the future development of those properties. If it is your intent to acquire additional property, it appears that your present preliminary plat application may be premature. The State Environmental Policy Act requires that the total project be reviewed for environmental impacts. The second point of concern is a question of soils stability and water runoff. A preliminary soils report might be advantageous considering the economic costs of possible mitigating measures. It will be a staff recommendation that preliminary plat be conditioned to- require engineered control and possible retention of storm water runoff. Your application will be processed as submitted. Additional information may be submitted for consideration before the staff report is written on 13 December 1978. Sincerely, 171E) .7.1.3616-- Roger J. Blaylock Assistant Planner RJB /ch cc: Ping.

November 20, 1978 Signature and Title Date STEPAN & ASSOCIATES, INC. X • • ENVIRONMENTAL CHECKLIST FORM ATTACHMENT I. BACKGROUND 6. The proposed project is a single - family residential subdivision consisting of 15 home sites on 4 acres of land. All lots are to be served with public streets, public water and sanitary sewers. Under the existing zone classifi- cation, R- 1 -9.6, the minimum lot size will be 9,600 square feet. The purpose of this project is to provide quality residential building sites to meet the urgent demand in the general area. 7. The project is located on the west side of 54th Avenue South, and between South 164th Street and South 166th Street in City of Tukwila. The property is moderately sloping terrain, ranging from 6 - 20%, falling from west toward east. Currently, the site is uninhabited, but may have undergone some grading previously during the construction of I -5. Adjacent on the north, west and south are single - family residences. II. ENVIRONMENT IMPACTS 1. Earth One surface soil is found on this site per King County Soil Survey, 1973, which is classified Arents, Alderwood material, 6 - 20% slopes (AmC). Runoff is slow to medium, and the hazard of erosion is moderate. This soil has a moderate limitation for foundations due to seasonal high water table and slope. Approximately 70% of the site will be graded to accommodate roads, utilities and home sites. Storm water erosion will increase but will be mitigated by installa tion of temporary (during construction) and permanent retention facilities, per City requirements. 2. Air Approximately 30 cars will be associated with this development and will contribute to CO, NO, SO4 emissions found in the ambient air. Fireplaces will be constructed in homes and will contribute smoke and other particulate matter to the ambient air. During construction, objectionable odors and dust may be encountered with street grading, paving and /or roof surfacing. 3. Water Impervious surfaces created (driveways, roofs, etc.) will undoubtedly increase surface runoff quantities and rates. Suspended soils and hydro- carbons may potentially contaminate runoff waters. Groundwaters, infiltration and aquifer recharge will be decreased. Storm water drainage will be designed and construct in accordance with the City's standards. Sufficient pollution control facilitie will be constructed to screen contaminants entering the natural drainage system. ENVIRONMENTAL CHECKLIST FORM - ATTACHMENT Page 2 4. Flora The tree cover of the site is predominantly deciduous with interspersed conifers. Approximately 50% of these trees will be cleared in the areas where roads, utilities and building construction are located. Approximately 75% of the underbrush of the entire site will be removed, including salal, berries, ferns and other native brush. A landscape plan has not been accomplished to date; however, many existing trees, in conjunction with the new planting materials, will be worked into a landscape plan for each lot. 5. Fauna Eighty percent (80 %) of the existing habitat, including common squirrels, chipmunks and other small native animals or birds will obviously have to relocate as the result of this development. Domestic pets can be expected with this development and can be expected to limit the rebuilding of natural species. 16. Utilities All utilities listed above are available to the site. Extension from these existing utilities systems will be required to provide adequate service. The existing utilities are adequate in both location and capacity. Storm water collection and retention systems will be constructed per County's requirements and approved West Campus Master Drainage Plan. r— I k. 701-1=1::, - 1 0 11 H- kHTt s57-7/0 .1.1--r*1 ■ ? r-ce.r=) 0'!')
