You may wish to respond to the City of Tukwila as follows: The only recommended, improvements to the project are those associated with the maintenance of adequate sight distance on S. 133rd Street. We believe that minor "tree- trimming" will be sufficient. We do not have right -of -way maps available; therefore, we are not in a position to determine whether or not the trees are on public or private property. However, if the trees are on private property, it is our under- standing that the city, through its police powers, can effect the necessary trimming. All other recommendations pertain to the continued traffic monitoring of the site following its full implementation to check -out functional operations. No other recommendations are suggested. I believe that the above . should be sufficient for the comple- tion of the Threshold Determination, Actually, I am quite pleased that this is the only item in . the entire report that needed clarification. Incidentally, I am not sure if you have right -of -way maps extending to the referenced intersection. If you do, you might wish to have your surveyors "spot" the trees to:.de- termine whether or not they are on public or private property. C. V. Brown, P.E.

Estimates of potential traffic impacts and mitigating measures used to alleviate adverse, impacts, if any, are derived for the arterial and collector street systems serving the project area. Figure 1 is a vicinity map indicating the location of the project site. Existing Facilities The project site is bounded by SR -599, a multi -lane, full access controlled freeway. This facility serves as the border on the northeast portion of the property. The south- west portion of the property is bounded by S. 132nd Street while the northwest and southeast portions consist of "unimproved" roads, 43rd Place South and 44th Avenue South. S. 132nd Street, the collector road serving the project site is a 2 -lane facility with light bituminous pavement, lane widths of approximately 11 feet, and shoulders varying in width from 2 to 4 feet. Overhead illumination is provided. STOP sign control exists at the intersections of S. 133rd Street and 42nd Avenue S. with both of these facilities acting as arterials. Land use in the immediate vicinity of the project site is "transitional" in that it consists of a few single - family residential facilities the majority of which have been converted to commercial uses. Southeast of the project site is an abandoned gas station now used as a storage facility. West of 42nd Avenue South, however, current land use is residential with some scattered institutional activities such as the Bethel Baptist Church at 42nd Avenue S. and S. 133rd Street serving as an example. For traffic purposes, the land use may be classed as "fringe ". 42nd Avenue S. has also been recently repaved over its 2 -lane section. Shoulders vary in width from 2 to 4 feet and overhead illumination is provided. No sidewalks or other pedestrian amenities exist on this road. -1- chri topher grown 9688 rainier avenue a tel: 7234567 x ashin;to • 18 j 1 CITY OF TOKWILA -2- FlGURE i �/rc/iVirt' MAP South 133rd Street passes below 42nd Avenue South. The bridge clearance is signed at 13' -6 ". At the SR -599 inter- change, overhead illumination is provided as a part of the interchange lighting. Parking is prohibited along this linkage up to the intersection of Interurban Avenue. Interurban Avenue is a 2 -lane roadway in the vicinity of 42nd Avenue South and is widened to four lanes (52 feet, shoulder -to- shoulder) south of the SR -599 northbound off - ramp. A separate left -turn lane is provided for northbound traffic to enter. S. 133rd Street as well as the northbound on -ramp to SR-599. South 133rd Street in the immediate vicinity of the SR -599 interchange is 35 -feet in width providing a single westbound lane and two eastbound "approach" lanes. Traffic Control Major traffic control installations include signalization at the intersection of Interurban Avenue and the southbound off -ramp of I -5 and a span -wire type signal, 2- phase, at the intersection of 42nd Avenue S. and Interurban Avenue. The latter signal is maintained and operated by King County, Division of Public Works. STOP sign control exist on all facilities entering S. 133rd Street as well as 42nd Avenue S. thus suggesting their arterial status. A STOP sign exists at the intersection of S. 133rd Street and Interurban Avenue. Interurban Avenue has a posted speed limit of 50 mph (trucks 40 mph) . The likelihood of this speed limit remaining in force is open to some question. No major traffic control projects are under consideration at the present time. Transit Metro Bus Route 123 operates on 42nd Avenue S. while Route 154 operates on Interurban Avenue. Traffic Characteristics Current traffic characteristics were researched from the files of the City of Tukwila, Department of Public Works, the Transportation Improvement Plan by Entranco Engineers dated -3- chrittopher brown Fle 9688 rainier avenue & sc�attle waahin • ton tel:7234567 x•:118 October, 1979 (prepared for the City of Tukwila) , the Annual Traffic Report, 1978 published by the Washington State Department of Transportation, and from field surveys conducted by the consultant during the weekdays of December 17 -21, 1979. 1979 Average Daily Traffic (ADT) is depicted on Figure 2. It might be noted that estimates of ADT for SR -599 ramp volumes were made on the basis of "short sample counts" since esti- mates of ADT were lacking within the Entranco report and were not available from the files of the City of Tukwila. Similarly, ADT estimates on S: 133rd Street and 42nd Avenue South were also made on the basis of short sample counts. All short sample count data were expanded in accordance with normal factoring techniques. Comparison of peak hour data with that published in the Entranco report indicates slightly reduced peak hour volumes this December. Discussions with staff of Planning Survey, Washington State Department of Transportation, indicate that statewide there is a reduction in traffic demand. In any case, the data of Figure 2 portray the actual peak hour demands as determined from December 1979 field counts. As in the case of the Entranco study, no "seasonal" adjustment has been made. Table I provides an estimate of Hourly Variation by Time -of -Day. The percentage distribution was derived from machine count data provided by the Washington State Department of Transportation for Interurban Avenue north of I -5.

Note that this is a schematic representation showing the principal orientation to major arterial and freeway facilities. Figure 5 is the Directional Demand Hourly Volume (DDHV) for the project site. This figure depicts the estimated peak hour turning movements. Recognizing that the Trammell Crow project is under construc- tion and, further, that the turning movements depicted in the T.P. & E. Access Plan have been modified so that the Interurban Avenue access road can accommodate only a "right -in, right -out" movement, a revised peak hour trip distribution was produced. This is depicted on Figure 6. The purpose of Figure 6 is to allow opportunity to incorporate both the revised Trammell Crow hourly demand in concert with those of the Northwest Medical Industrial Park in order to obtain estimates of cumulative demand. Figure 7 shows the it is assumed that Medical Industrial operational. -7- estimated 1980 -1981 DDHV.

In other words, there is a distinct peak in the morning (northbound) and almost identical and equally distinct peak in the afternoon (southbound) depicting work activities rather than shopping- social - recreation acti- vities. This is typical for a small community with substantial commuter trips on thru facilities. In order to document the influence of trucks and buses within the traffic stream a vehicle classification study was under- taken on Interurban Avenue at the S. 133rd Street intersection. The study was conducted on 12/17/79 in the afternoon. The sample size was 490. The data are described below in Table II. TABLE II VEHICLE CLASSIFICATION Vehicle Type of Total Standard Auto 42.7 Compact Auto (1) 24.3 Pick -up Trucks /Vans 25.2 Trucks, 3 axle 1.8 Trucks, 4 axle 0.2 Trucks, 5 axle 3.9 Buses (2) 0.6 Motorcycles 1.3 (1) Compact vehicles include Datson and Toyota pick -up trucks. (2) Metro Buses only, no school buses observed (3) Data excluded one mobile crane (4) Only one pedestrian observed during the one hour interval For capacity purposes, the "T" factor may be taken at 6 percent. The influence of buses can be ignored. Trip Generation The proposed Northwest Medical Industrial Park consists of two buildings. The proposed building sizes are: -12- Building lA 6350 Building 1B 6200 Building 1C 10850 Subtotal 23400 Christopher brown P\ 9688 rainier avenue s. to :7234567vashinL 98118 • • Adverse Consequences In terms of oeverall traffic impact the Northwest Medical Industrial Park produces about the same volume of traffic as a 30 -unit residential development. The 276 vehicles per day produced by the facility is relatively small while the maximum hourly demand of 90 VPH is similarly minor. The intersection of the site's main access road at S. 133rd Street currently has a sight distance obstruction to the east, namely a cyprus and willow tree. These may need to be "trimmed back" in order to improve visibility in the easterly direction. The access roadway from the site leading onto 42nd Avenue S. has a slight up- grade. This grade could interfere with truck operations, particularly during periods of inclement weather. Nevertheless, since alternate routes do exist this is not considered a serious constraint. While some of the local roads have been repaved, the road surface immediately in front of the project site has not been repaved. The surface condition might suffer from further deterioration. This aspect is beyond the scope of this study report. The imposed traffic from both the Northwest Medical Industrial Park project as well as the Trammell Crow project will not increase traffic volumes at the intersection of S. 133rd Street and Interurban Avenue to an extent where traffic signalization will be warranted. The approach volumes taking place in the lowest hour of the eight highest hours of the day are: North leg, southbound 267 South leg, northbound 250 West leg, eastbound 117. Although traffic signal warrants will not be net by virtue of these two projects, additional development in the immediate vicinity may be sufficient to increase traffic volumes so that warrants will be met. Indeed, it is possible that the absence of warrants may lead to a sufficient accident frequency that a signal could be installed under Warrant 6, Accident .Experience. It should be pointed out that the distribution of Figure 7, 1980 -81 DDHV, indicates a relatively heavy right turn demand form S. 133rd Street in contrast to an extremely light left - turn demand from 133rd to Interurban Avenue (northbound) . -• This is because opportunities for entering Interurban Avenue, during peak hours, are infrequent so that vehicles will divert their trip to 42nd Avenue and gain access to Interurban Avenue via the existing traffic signal. -13- Christopher brown pe 9688 rainier avenue a attle washin • ton 7234567 '•:118 • • With respect to the intersection of S. 133rd Street and Interurban Avenue, the additional volume produced by the proposed site will not be sufficient to warrant signaliza- tion of the intersection. Consequently, in the absence of signalization, some delay or congestion will be experienced during the peak hours. Should such delay increase substan- tially, additional trips may divert from the project site to 42nd Avenue S. and thence to the signalized intersection of 42nd at Interurban Avenue. However, such diversion will rot increase traffic volumes beyond that which can be safely and expeditiously accommodated at the traffic signal. Adequate levels of service. will continue to exist, even during the peak hour. Nevertheless, close attention will be required as other projects come an-line since relatively heavy turning movements, particularly from the east to the north and from the north to the east could warrant the inclusion of separate signal phasing with coincident increases in cycle length and consequent increases in delay. For the purposes of the project under consideration, however, adequate levels of service will remain in effect. No alteration to the signal system is suggested. Mitigating Measures Although this project imposes but little traffic demand to the system, the principal mitigating measure involves the • continued monitoring of traffic operations on Interurban Avenue particularly at the intersection of S.' 133rd Street. As other projects develop, it is possible that signalization may be required with signal implementation set for the time. interval 7:00 to 9:00 a.m. and ..11 :00 to 6 :00 p.m. In addition, monitoring of the intersection of 42nd. Avenue South and Interurban Avenue will be 'necessary to ensure that the signal system will continue. to function' properly. • In the immediate vicinity of the project site, ,particularly on S. 132nd Street, .improvements to sight distance at :S. 133rd Street should be implemented. Also, a review of the curb return of S. 132nd. Street at 42nd. Avenue S. (northeast quadrant) might be in order if the project (use:) require 'relatively large trucks. At the present, the proposed Medical Industrial Park will likely involve trucks no larger than about 16, 0.00 g.v.w., a truck whose size should function adequately on' the existing system. Finally, monitoring of the pavement surface may be necessary to ensure the viability of the collector roadway. During construction of the project site as well as on -going activities following construction, the pavement surface. may suffer. -14- christopher brown pe 9688 rainier avenue a Lei 7234 %7Whin •ton '•'118 • Conclusions It is concluded that the implementation of the Northwest Medical Industrial Park project will produce additional vehicular traffic. During the peak hour, overall traffic volumes will increase by about 90 vph. Implementation of the project will not produce signal warrants at the intersection of Interurban Avenue and S. 133rd Street nor will capacity be exceeded at the existing signalized intersection of 42nd Avenue S. and Interurban Avenue. Without the signalization at S. 133rd Street and Interurban Avenue, side street traffic (S. 133rd Street) attempting to enter Interurban Avenue during peak periods may increase accident potential. Generally, such accident potential is from side street traffic attempting to utilize gaps in the traffic stream that are less than the critical gap. Generally, the arterial and highway systems in the vicinity of the project site appear to be adequate for accommodating he relatively minor traffic that will be generated by the project. However, continued_ monitoring of the situation will be required so that appropriate remedial measures can be implemented should such measures be required. -15- chri8topher Brown 9688 rainier avenue a 72 56Washin ;t.118� Ci`y of Tukwila dt2►G Administration 6200 Southcenter Boulevard Tukwila, Washington 98188 433 -1845 Office of Community Development 16 November 1979 Bittman, Sanders, Hasson & Assoc. 406 Securities Building Seattle, WA. 98101 Attn: Dave Hasson, Project Planner Re: Proposed Northwest Medical Supply Industrial Park Enclosed is a copy of the analysis made by this office on 14 November 1979 of the Environmental Checklist submitted in conjunction with an application for grading permit for the subject project.

Bauch, Maya' MEMORANDUM Kjell Stoknes, Director O.C.D. Mark Caughey, Asst. Planner 14 November 1979 SUBJECT:. Environmental Analysis - Bittman /Sanders Et.AI. Grading Permit Application INTRODUCTION: The applicants have filed an application for grading permit, with environmental checklist, to begin preliminary site development of a two -phase office /warehouse complex for a distributor of medical supplies and related tenant spaces. The proposed project is located within the general boundaries of Interurban Avenue, South 133rd Street, and 42nd Avenue South. Current zoning and comprehensive planning designations for this site are "light industrial ". ANALYSIS: Growth- Inducing And Land -Use Commitment Implications Of The Project: The subject site is part of an extensive area of vacant lands with a few abandoned buildings at the northerly edge of. Tukwila. This project, if approved for construc- tion, will mark the first advance of industrial usage in the vicinity, and will probably set the tone for development potential on adjacent properties. In fact, the applicants are already anticipating such complementary development, as indicated by their response to Section I -11 of the checklist. The proposed project will require tHe. extension of utility services from existing water and sewer mains on South 133rd Street. These extension lines to be placed in South 134th Street will of necessity be sized to match.the consumption and discharge demands of industrial use, thus adding further impetus to commit the area to long- term industrial or commercial usage. In our preliminary discussions of this project with the applicants, this office indicated that some legitimate potential may exist for use of this site and its immediate surroundings for higher density residential development. While current growth levels in the King County metropolitan anticipate the need to increase the region's stock of rental housing, and while the strategic location of this site in relation to nearby employment centers suggest its suitability for residential development, other "site- specific" factors present in the environmental setting seem to militate against that suitability: Kjell Stoknes Enyironmental Analysis - Bittman /Sanders Surrounding Residential Density Levels Page 14 November 1979 Residential neighborhoods to the immediate north and west of the site are single - family in character, at relatively low density, and are outside the City limits proper. While higher density adjacent to Interurban Avenue would be a legitimate example of the land -use buffer concept, the abrupt change in visual character of the neigh- borhood occasioned by the eight and bulk commonly associated with higher- density tend to fragment neighborhood identity and produce a sense of isolation for dwellers in the higher- density projects. Lack of Convenient Support Services The subject site is located a considerable dis ance from the kinds of daily - living supply and service outlets whic would be needed to accommo- date a large population nucleus. Food -sto es, personal care services, and specialty shopping are all outside of the area's pedestrian -scale market radius; accordingly, access to th se services will add vehicle trips to the surrounding street network, exacerbat capacity and volume demand levels, will increase non - renewable energy usage, and will degrade air quality and noise levels in the community. Proximity To Interurban Avenue and Route 99 The literature contains some evidence of adverse human health impacts associated with long -term, close -range exposure to the noise and emissions of high -speed traffic arterials. Concentrated housing on the subject site could constitute a long -term hazard to certain persons who are susceptible to respiratory difficulties. While some of the noise and air quality problems resulting from vehicle traffic can be controlled through architectural techniques and design of the mechanical system, the high cost of such improvements may not be recoverable -in the near - term rental return structure, and may be opposed strenuously by the development interests. For these reasons, it is my opinion that the original use contemplated for this site and its immediate vicinity, i.e. light industry, should be affirmed without modification. Environmental Impacts: Water Resource Management The applicants' response to Section II -3 of the checklist indicate that a significant degree of modification of on -site hydraulic conditions is anti- cipated with implementation of the project. The conceptual hydraulic plan, Sheet G -1, was examined by the Public Works Department. Their comments are as follows: Provide more detailed calculations of run -off generation and determine the amount of retention volume necessary. Provide construction details for rechannelling of the intermittent creek on the west side of-the site. Of special concern is the proposed method and materials for constructing the channel and protective measures to be used for minimizing siltation and obstruction by water -borne debris. Kjell Stoknes Page 3 Environmental Analysis - Bittman /Sanders 14 November 1979 Environmental Impacts: Risk of Upset The applicants' response to Section II -10 of the checklist seems contradic- tory. It seems that the project is intended to accommodate hazardous sub- stances, consistent with the nature of businesses permitted in light - industrial districts. Therefore, it seems that the City has sufficient controls at its disposal to regulate the presence of these materials on the project site without redundancy. A cautionary comment from the Police Department's Crime Prevention Division involves storage of narcotics on the project premises. They request that solid masonary walls dividing tenant spaces be provided to impede theft of these substances. While the principal tenant of this project, Northwest Medical Supply, may not handle such drugs, it is conceivable that one of the "spec- space" lessees might do so, and appropriate security measures should-.be planned into the project at its inception. Environmental Impacts: Transportation /Circulation The applicants' supplemental response to Section II -13 attempts to quantify the impact of this project on the adjoining local street network. The Public Works Department, however, finds this information incomplete, and is in fact concerned about the cumulative effect of this project, and others like it which may be attracted to the area, upon the intersection capacities of 133rd at Interurban and 42nd at Interurban. Also, the trip - generation factor suggested by the applicants is unsubstantiated since anticipated total employ- ment is not given. Therefore, the Department requests submission of a formal traffic report for the project, prior acting upon the final determination of environmental significance. Note in Section I -11 that the applicants intend, at staff's suggestion, to attempt to implement a shared access system with the adjoining property to the southeast at such time as it develops, and with cooperation of the City. Recommendation Final action of the responsible official relative to the environmental signifi- cance of the project should be suspended until the following supplemental information is received by this office and evaluated: 1) A Comprehensive Hydraulic Analysis with storm water retention calculations, proposed grading contours, and a detailed solution for rechanneling the on -site stream course. A Traffic Study including anticipated trip - generation factors for the proposed warehouse /office complex, and a quantitative discussion of intersection capacity impacts of this development, and similar development of adjoining property, at 133rd /Interurban Avenue and 42nd Ave. S. /Inter- urban Avenue.

Committee working on Councilman Hill reported the Public Safety Committee is meeting on Wednesday at 4:30 p.m. They will discuss the leash law and its enforcement. The public is invited to attend the meeting. Council President Saul reported that the pump at the Fire Department blew up and it will cost $16,000 to replace it. Council President Saul reported it is being investigated as to whether or not an individual must be a citizen of Tukwila in order to be on the Planning Commission. Councilman Harris said she has always felt that in small cities the business people live in town and are representative of the City where their business is located. She said Tukwila is unique in that few of the people who own businesses live in the City. She said she felt we should have some representation from these people. Council President Saul said some property on Mall Avenue can be traded for.the same amount of property along the river adjacent to the park. This item should be put in the Community Affairs Committee. Council President Saul reported that many complaints were being received about odors coming from the Rendering Works.

Signature a Title -8- October 16, 1979 Date x x x • • CITY OF TUKWILA ,ENVIRONMENTAL CHECKLIST FORM Attachment 1 I. BACKGROUND 6. Construction of an industrial park composed of two on -grade tilt -up warehouses for manufacturers' representatives requiring small warehouse areas for their goods. Only small delivery type vans and trucks will be servicing the areas; no arrangements will be made for the loading and unloading of road rigs. Office areas will be provided. The buildings will be designed to be architecturally pleasing and the grounds will be landscaped to enhance the structures. The total combined building area is 60,800 square feet. Parking for over 125 cars will be provided. 7. The property is located on South 134th Street, between the un- developed.rights -of -way 44th Place South and 43rd Avenue South, and bordered to the northeast by the I -5/99 freeway junction. The land is brushy and barren, sloping away from 134th to lower elevations at the side bordering the freeway. There is a small stream bed, dry most of the year, but carries winter run -off to the Duwamish River. It would be relocated to the side of the property in an open ditch condition, and probably used to carry surface run -off from the subject site. The land is rather low and will be raised with free - draining, compacted fill to maintain a proper relationship with 134th Street, and to insure proper site drainage. The legal description is as follows: Lots 2 t 19, inclusive, Block 3, and Lots 2 to 8, inclusive, Block 2, Riverton Replat of Lots 1 to 5, inclusive, Fostoria Garden Tracts, according to the plat recorded in Volume 13 of Plats, page 40, in King County, Washington, EXCEPT those portions thereof condemned in King County Superior Court Causes No. 618285 and No. 620213 for Primary State Highway No. 1, TOGETHER with that portion of vacated 43rd Place South adjoining. CITY OF TUKWILA ENVIRONMENTAL CHECKLIST FORM Attachment 2 II. ENVIRONMENTAL IMPACTS 1. (b) There will be fill over entire land area of the actual building site, plus an additional 20 feet outside the building site boundaries. In addition, the balance of the property needs to be filled and raised approximately 2 feet above the current grade (building grade will be slightly higher than periphery to assure drainage away from structures). (c) Changes in topography and ground surface relief features will be revised to the extent noted in the statement above. 3. (c) Construction of the building closest to 134th Street (Phase II) will require changing the course of the stream. Placing and regrading of fill material will . require protection measures, such as hay bales and a silt fence. Both processes will be designed and executed with the goal of reducing possible soil runoff to a minimum. (f), (g) There is an existing stream, dry most of the year, to be relocated to the edge of the site in an open ditch condition. It presently carries surface water runoff to the Duwamish River. It will be assumed by the proponents of this proposal that this existing stream has the capability to safely discharge the surface water runoff of the proposed project to the Duwamish River when combined with a properly engineered retention system with a control orifice to meter discharge into said stream. 13. (a) On the basis of approximately 3 in -and -out movements for each vehicle (other than trucks), this would mean approximately 750 vehicle trips a day based on the 125 parking spaces provided. However, many employees' cars will not move all day. No large trucks are anticipated and no truckbed loading docks will be provided; truck trips per day are difficult to predict without knowledge of tenants' businesses. (b) Parking will be provided for 125 cars, plus truck stalls, for each subdivision of warehouse. MIRAF1. 1•0 FASO-0C s ILT CONTROL-' FILTER.: FASTEN...
