Summary of Mitigation ...................................... 31 INTRODUCTION This report summarizes the traffic analysis which was conducted to assess the impacts of Nelson Motors proposed new car dealership. The analysis was designed to address the net traffic impacts associated with replacing the existing mobile home park with a new car dealership. Where the analysis Identifies adverse traffic Impacts due to the project, mitigating measures are suggested which would reduce or eliminate the effects of these impacts. The project site is located near the site of a proposed Top Foods warehouse -style grocery store for which The TRANSPO Group recently completed an extensive traffic analy- sis. The scope of the Top Foods analysis was determined in cooperation with City of Edmonds staff and transportation staff representing neighboring agencies. The scope for this Nelson Motors analysis was determined in cooperation with City of Edmonds staff based on the findings of the Top Foods analysis. The proximity of Nelson Motors new car dealership project site to the Top Foods site has allowed the Nelson Motors traffic analysis to build on the findings of the Top Foods analysis. Portions of the Top Foods report are directly applicable to the Nelson Motors analysis and have, therefore. been reprinted herein, though often in less detail. Examples of areas which the two projects have in common include: existing conditions, proposed transportation Improvement projects. background traffic growth, baseline traffic volumes, and. to some extent, recommended mitigation measures. Project Location Nelson Motors new car dealership site is located In the City of Edmonds In South Snohomish County. Figure 1 illustrates the site location. The site Is located in the southwest comer of the intersection of two major commuting hnks—SR 99 and 220th Street SW. A number of other jurisdictions have boundaries near this intersection. The City of Mountlake Terrace lies to the east, Lynnwood lies to the northeast (but has operational responsibility for SR 99 traffic signals). and Snohomish County lies immediately across SR 99 to the east and southwest of the 220th Street SW/76th Avenue W intersection. 90371.50\903715Rl The TRANSPO Group, Inc.

Page 4 EXISTING CONDITIONS Street System The site is bounded on the east and north by two major arterials. It is located at the southwest comer of SR 99 (north -south) and 220th Street SW (east -west), with access onto both. SR 99 is a major, five -lane commuter route and links a number of nearly continuous commercial areas stretching over six miles. It therefore carries high commuting volumes plus shopping, recreation, and business trips in and between several jurisdictions. It is laid out at a diagonal, with reference to the standard street grid. so that it Intersects both streets and avenues at irregular intervals and land angles. It also has "strip commercial" and major retail centers along both sides, creating frequent driveway intersections. 220th Street SW links the residential areas of Edmonds to the west, to the shop- ping and services on SR 99. to the 1-5 freeway, and to Mountlake Terrace to the east. It is a four -lane wide street adjacent to the project site. widening to five lanes at SR 99. West of 76th Avenue W. it narrows to two lanes with on -street parking on both sides of the street. East of SR 99, it is a continuous five -lane section through Mountlake Terrace to 1-5. Other major north -south streets in the pmJect vicinity include 76th Avenue W and 84th Avenue W. 76th Avenue W Is a four -lane street in the project vicinity. It directly serves Edmonds High School and the Stevens Hospital complex, between 220th and 212th Streets SW. 84th Avenue W is a local collector street, with four-way stop control at 220th Street SW. The study area was coordinated with City of Edmonds staff. Specific intersections which were identified for operations ana]ysis, including current traffic control and control- ling Jurisdiction, are as follows: SR 99 at 212th Street SW (s4�nalized).

Traffic Volumes and Level of Service Traffic volume information was based on counts performed in September 1989 and January 1990. Figure 3 shows the existing PM peak hour traffic volumes in the project vicinity based on these counts. Existing PM peak hour levels of service (LOS) were calculated at the major Intersec- tions in the study area using the 1985 Highway Capacity Manual (Transportation Research Board) methodology. Level of service is used to evaluate and quantify operating conditions and traffic congestion at Intersections. Level -of -service values range from LOS A. Indicating free -flowing traffic. to LOS F. indicating edmme congestion and long vehicle delays. Spe- cific level -of -service criteria for signalized and unsignalized intersections are presented in the Appendix. At signalized intersections, level of service is measured in terms of the average vehicle delay. While calculated average vehicle delay is the criterion used to define signalized level -of -service ranges, it becomes less meaningful as an indicator when an intersection is operating in the LOS F range. Delay calculations are oversensitive to small changes in traffic volume in the LOS F range. In these cases, the volume -to -capacity ratio (v/c) can be a more representative indicator of actual operational change than calculated average vehicle delay. The v/c ratio reflects the relative amount of critical intersection traffic. compared to an Intersection's capacity. At Intersections where stop signs control the minor legs, level of service is measured in terms of the reserve (or unused) capacity available for critical turning movements. At four-way, stop -controlled intersections, level of service is measured in terms of the volume - to -capacity ratio. Table 1 summarizes the results of the analysis of the Wsting PM peak hour level of service at the study Intersections. 90371.50\903715Rl The TRANSPO Group, Inc.

The existing level of service reflects the heavy volumes on the major arterials in the project vicinity with many signalized intersections currently operating at LOS E. This is typical of traffic operation conditions on SR 99 and other major arterials throughout South SnohomLsh County. The traffic signals along SR 99 and 220th Street SW are interconnected, with their signal timing patterns coordinated to allow progressed mainline traffic flow. This can lead to less than optimized operations at individual intersections in order to better serve the total signal system. Side -street traffic flow, in particular. is often compromised to meet coordinated signal timing requirements. At the unsigrialized intersection of 216th Street SW/SR 99, westbound traffic oper- ates at LOS F during the PM peak hour. The majority (93 per -cent) of the current west- bound approach traffic turns right. Very few vehicles currently attempt to cross or tum left onto SR 99 at this location due to the uncontrolled 216th Street SW approaches and heavy SR 99 thru. volumes. 90371-50\903715Rl The TRANSPO Group, Inc. Page 8 This location currently meets the Manual on Uniform Traft Control Devices (MLFrCD) Warrant No. 2 - Interruption of Continuous Traffic and Wan -ant No. 5 - Accident Warrant. A traffic signal at this location on SR 99 would be ideally situated between existing signals at 212th and 220th Streets SW; thus, future interconnection to the SR 99 signal system could easily be accomplished. Traffic Accidents Historical traffic accident data at the study area Intersections for the years 1986- 1989 were obtained from WSDOT District 1. the City of Edmonds, and the City of Mountlake Terrace. These data were reviewed and analyzed. WSDOT has indicated that the section of SR 99 fronting the project site is considered a high accident corridor within District 1. Three of the study area intersections reflect relatively high occurrences of angle and turning accidents: SR 99 at 220th Street SW, SR 99 at 216th Street SW. and 220th Street SW at 66th Avenue W. At SR 99/220th Street SW. the majority of the angle or turning accidents involved vehicles on the westbound approach of 220th Street SW. The combination of these types of accidents averaged 11 per year in 1987 and 1988. The occurrence dropped to six per year in 1989. There are two contributing factors which affect the accident frequency at the SR 99/ 220th Street SW intersection. First, drivers of westbound thru and left -turn vehicles appear reluctant to stop on the uphill grade if they can instead proceed through the inter- section on the green or yellow phase of the signal cycle. Therefore, there may be a tendency for some drivers to proceed through the intersection at the end of the yellow phase, puffing them in the center of the intersection during an opposing green phase and creating a potential for conflict with SR 99 traffic. A second factor contributing to accident frequency is a result of the progressed signal timing pattern on SR 99. SR 99 traffic progression is favored over side -street traffic flow to maintain and maximize north -south flow. At 220th Street SW. the current timing plan creates relatively long delays on the side streets which can contribute to drivers 90371.50\903715Rl The TRANSPO Group, Inc. Page 9 becoming impatient and running the yellow phase. If the high accident rate continues, the possibility of retiming of the signal phases to allow more green time on 220th Street SW or lengthening of the yellow or all red phases should be evaluated. At SR 99/216th Street SW, an unsignalized intersection. an average of seven accidents occurred per year from 1987-1989. Angle accidents would be correctable by proper signaliza- tion of the intersection. This location meets MUTCD traffic signal Warrant 5 - Accidents. Seven accidents exceeds the minimum warrant requirement of five accidents by 40 percent. At 220th Street SW/66th Avenue W. there is an increasing number of accidents involving opposing left -turn and thru movements on 220th Street SW. This type of accident is currently occurring at a rate of four or five per year. When the accidents consistently occur at ftve or more per year. the permissive portion of the protected/permissive left -turn, phase on 220th Street SW should be reconsidered and possibly removed. Pedestrian and Bicycle Activity Pedestrian and bicycle activity in the Immediate site vicinity is generally low. SR 99 is not conducive to pedestrian travel, with no defined sidewalks and varying degrees of refuge from vehicular traffic. The strip development prevalent along these streets does not generate substantial pedestrian activity, except related to parked vehicles. 'Ibis is due both to the low density of strip development (from a pedestriaifs perspective) and to the types of land uses which locate along strip commercial corridors. West of the site, in Edmonds. higher pedestrian activity occurs adjacent to existing residential development. In most cases, sidewalks are provided along arterUds (220th and 212th Streets SW, 76th and 84th Avenues W). Transit Service The area is served by transit. with routes running on SR 99, 220th Street SW. and 76th Avenue W. However, transit is not anticipated to play a major role in serving proposed site development, since car dealerships are predominantly passenger -vehicle oriented. Therefore, specific transit service information was not developed. 90371.50\903715RI The TRANSPO Group, Inc. Page 10 FORECASTED CONDITIONS WITHOUT PROJECT This section of the report highlights those elements of existing conditions which are likely to substantially change between current and 1992 conditions. 1992 conditions with- out the project become the baseline against which project traffic impacts are measured. 1992 was selected as the analysis horizon year since it is the first year during which the project could be constructed and occupied. By selecting a near -term horizon. the relative impacts of project traffic are maximized. A later horizon year would evaluate the effects of longer term, nori-project traffic growth; however. project traffic would be proportionally less of the forecasted conditiorL To determine forecasted conditions without the project, changes to three primary analysis elements must be Identifted. FIrst. changes to the existing street system which are likely to occur by 1992 are listed. Next, increases in current PM peak hour traffic are forecasted. Then, 1992 Intersection operations (level of service) are calculated considering both increased traffic volumes and modified (where appropriate) intersection/street system channelization. Planned Street System Improvements A number of documents have previously guided transportation Improvement plan identification for the site vicinity. The 1987 College Place Traffic Study (Bell -Walker Engi- neers for the City of Edmonds) proposed a number of transportation improvements. Other studies identified longer range transportation improvements, Including the 1986 Alderwood North Creek Transportation Study (ANCTS) and the 1987 South Snohomish County SR 99 Corridor Study. both conducted by the Puget Sound Council of Governments. On June 19, 1990, Edmonds City Council adopted Resolution No. 700, a six -year (1991 through 1996) Transportation Improvement Program (TIP). Table 2 summarizes the location. type. cost. and schedule of TIP projects located in the project vicinity. 90371 _5M715R1 The TRANSPO Group, Inc.

A number of these projects would have a positive effect on level of service and should be taken into account In the 1992 baseline level -of -service armlysis. These include: SR 99/216th Street SW - Signalization will Improve traffic operations at this location. It is the highest priority project of all Intersection improvements listed in the 71P and is scheduled for 199 1. 0 220th Street SW/84th Avenue W - Signalization is scheduled for 1992. SR 99 Widening - Although this project is scheduled for 199 1, the time required to perform design studies and acquire necessary right of way will likely preclude completion of the widening until 1992 or beyond. However, the Improvement is the number one priority In the entire state and has all funding secured. Only an interlocal agreement needs to be completed prior to moving ahead. The improvement will not be assumed as part of the 1992 non -project condition, but the results of intersection operations with SR 99 widening will be illustrated in the project impact analysis section. 90371-50\903715RI The TRANSPO Group, Inc. Page 12 Improvements described in the College Place study, but not shown in the stx-year TIP include: 212th Street SW - Widen to five lanes between 76th Avenue W and SR 99. This would increase capacity at its intersections with 76th Avenue W and SR 99. 220th Street SW - The City of Edmonds has been working jointly with Snohomish County to develop a project to widen 220th Street SW from 76th Avenue W to 100th Avenue W. This project would widen 220th Street SW from four to five lanes at the 76th Avenue W Intersection, improving operations there. 7he project is programmed but unftmded. Snohomish County would be the lead agency for the project. The county applied for Transportation Improvement Board trm) funds for the project In December 1989 and the ftmds were denied. 1992 PM Peak Hour Non -Project Traffic Volumes To develop 1992 forecasted PM peak hour traffic volumes without the project, a two- step process was employed. First. existing traffic volumes were increased by an annual growth factor based on historical trends. Then, traffic from specifically Identified planned, but unconstructed, projects was added to develop forecasted 1992 non -project conditions. Existing traffic volumes In the pruject vicinity were Increased by an 8 percent annual growth factor to obtain traffic volume forecasts in 1992. This growth factor was based on the average historical traffic volume growth an SR 99, based on WSDOT traffic count data, and Is due to development in the North King County/South Snohomish County sub -region. The application of the growth rate used on SR 99 to the other streets in this study will provide a conservatively high estimate of project year traffic volumes. It Is unlikely that all of the area streets are experiencing as high a growth rate as SR 99, which is the major sub -regional north -south arterial in the area and experiences the effects of both local and sub -regional traffic growth. Further, since many study area intersections are currently operating at or near capacity, the potential for traffic volume growth during the PM peak hours is limited. Thus, the traffic forecasts may overestimate future PM peak hour traffic. 90371.50\903715Rl The TRANSPO Group, Inc. Page 13 Based on information supplied by the City of Edmonds. five other projects have been proposed in the area and building permit applications have been received or are in process. The five projects are expected to be occupied by 1992. Estimated PM peak hour trips generated by these five projects were added to the factored volumes. These projects are: Top Foods - An 85,000 sf warehouse -style grocery store with added customer service features. Krug-er Clinic - A 20,094-sf addition to the existing complex at the southwest comer of SR 99/216th Street SW. Stevens Oncology Cente - A 17,700-sf complex to be located adjacent Stevens Hospital to the southeast. Stevens Health Cente - An 8,350-sf addition to the complex just south of Stevens Hospital on the east side of 76th Avenue W. Grease Monkcy - A proposal to add a car wash to an automobile oil -change service center with two bays located on 212th Street SW between SR 99 and 74th Avenue W. A high annual traffic growth factor, together with the effect of adding traffic from five known developments, combine to result in a high PM peak hour 1992 traffic forecast base- line. Thus. this is a conservattve estimate in that it may overstate the severity of future traffic conditions, with or without the project. Figure 4 shows the resulting 1992 baseline PM peak hour traffic volume forecasts in the project vicinity. These volumes are identical to the 1992 condition with Top Foods Identified in the Top Foods DEIS. 1992 Baseline Level of Service Level of service was calculated at intersections in the study area using the estimated 1992 b-dfric volumes without the project. Table 3 summarizes the results of this analysis. For comparison purposes. existing levels of service (from Table 1) are also shown. These LOS results are consistent with the 1992 with -project condition discussed in the Top Foods DEIS. SR 99 at 220th and 212th Streets SW would continue to experience the highest congestion levels. which is consistent with current operations. Level of service would decline from LOS E to LOS F. Calculated v/c ratios In excess of 1.25 suggest that the PM peak hour traffic forecast may be somewhat high, resulting in intersection volumes over 25 percent higher than the intersection's capacity. The planned SR 99 widening to seven lanes would Improve operations at these locations. 90371.50\903715Rl The TRANSPO Group, Inc.

Page 16 PROJECT TRAFFIC VOLUMES PmJect traffic volumes were added to the surrounding street system according to a standard three -step process of trip generation, trip distribution, and trip assignment. When the net effect of project trips assigned to the street system is added to 1992 non - project traffic, 1992 cumulative traffic for impact analysis results. Trip Generation The number of trips generated by Nelson Motors new car dealership was estimated based on a body of data collected by The 11RANSPO Group over the last several years. This data has been supplemented by tube counts collected by the City of Edmonds at two Edmonds new car dealerships. TRANSPO has found that the number of service bays at a new car dealership is the best indicator of the number of PM peak hour trips which can be expected to be generated. Number of service bays is likely the best indicator due to the fact that a high pro- portion of customers stop by after work to pick up their cars which have been serviced during the day. Service bays are In direct proportion to a service department's ability to complete a volume of work. These customers are typically brought to the service depart- ment in a second vehicle. Thus, each car serviced would typically generate three trip ends, one In and two out. The proposed Nelson Motors new car dealership will have some of its floor area devoted to the display of power products. These products Include lawn mowers, snow blowers. and electricity generators. While the power products display area occupies an area which would otherwise be used for the display of cars, trip generation for this floor area was accounted for by applying an additional trip generation factor to be conservative. The additional rate accounts for the possibility that the power products, which are less expensive than new cars. generate trips at a higher rate than new car dealerships. Since no data are available for power products trip generation, the trip generation rate for a comparable land use was selected from among the rates published in Trip Genera- ttom Institute of Transportation Engineers (rM) 4th Edition. Furniture store was selected as the most comparable land use. This is a reasonable comparison, since the similar price 90371.50\903715Rl The TRANSPO Group, Inc. Page 17 range and life expectancy of furniture products and power products lead to similar shop- ping characteristics. The furniture store trip generation rate of 0.4 trips per thousand gross square feet (tgsO was used to estimate the number of trips generated by the power products display. Based on these trip generation rates. the Nelson Motors facility, with 20 service bays and 1. 1 tgsf of power products display, is estimated to generate 128 trips (68 in. 70 out) during the PM peak hour. ibis is equivalent to a PM peak hour trip rate of 6.4 vehicle trips per service bay. It should be noted that, while service bays is the independent variable used to forecast PM peak hour trip activity, the forecast encompasses aH PM peak hour trips to/from the dealership including automobile and power products sales customers. A trip generation rate was also estimated for a hypothetical worst -case scenario. The worst -case trip generation rate used was 9.0 PM peak hour vehicle trips per service bay. This is equivalent to the 85th percentile of the TRANSPO and City of Edmonds - collected data. Based on these worst -case trip generation rates, the Nelson Motors facility, with 20 service bays and 1. 1 tgsf of power products display. is estimated to generate 180 trips (81 in, 99 out) during the PM peak hour. This reflects about 40 percent higher trip generation than the average value used in the basic analysis. The probability of this worst - case trip rate being exceeded Is less than 15 p�rcent. Trips generated by the existing mobile home park, which would be replaced by the Nelson Motors project. were subtracted from the trips generated by the new car dealership after the trip assignment process. The number of trips generated by the existing mobile home park was estimated based on rates published in 7Wp Generattort, Institute of Trans- portation Engineers (n7) 4th Edition. Based on the ITE rates. a mobile home park can be expected to generate 0.559 trips per occupied dwelling unit. Thus, the 62 occupied mobile homes are estimated to generate 34 trips (21 in, 13 out) during the PM peak hour. Trip Distribution and Assignment Trip distribution and assignment for the Nelson Motors project was based on regional travel patterns and more localized turning movement volumes in the project vicinity. Figure 5 illustrates the percentage distribution of new trips on the primary streets providing site access. 90371-50\903715RI The TRANSPO Group, Inc. Page 18 The traffic assignment for the mobile home park (not shown) would be slightly dif- ferent from the assignment for the Nelson Motors project. reflecting the fact that the mobile home park does not have direct access to SR 99. 7hus, the combined effect of adding pro- ject traffic assignment and subtracting the mobile home park traffic assignment causes a nd reduction for a few turning movements at a limited number of Intersections. Overall. however, the effect of replacing the mobile home park with the new car dealership is to add trips to the local street system. When the net PM peak hour project traffic Impacts are added to 1992 PM peak hour volumes without the project, the forecasted with-prqJect traffic volumes in Figure 6 result. 90371.50\903715RI The TRANSPO Group, Inc.

Page 21 TRAFFIC IMPACT ANALYSIS The following sections address the primary elements which could be impacted by p roject traffic. These include 1992 level -of -service anabrsis, local street impacts, project access (driveway operations), safety, pedestrian and bicycle activity, transit, and parking. Where project traffic impacts are Identifted. alternatives to mitigate the impacts may also be explored. 1992 Level of Service with Project Table 4 summarizes the results of the 1992 with -project level -of -service analysis using 128 vph average trip generation developed in the preceding section. For comparison purposes, levels -of -service for 1992 non -project conditions (from Table 3) are also shown in Table 4. A worst -case analysis was performed at the intersections of SR 99/220th Street SW and 220th Street SW/76th Avenue W using the 180 vph worst -case trip generation. These intersections were selected since they represent the two locations which are likely to receive the highest project traffic Impact. The results are also summarized in Table 4. The impact of the project on traffic operations can be illustrated in a number of ways including: relative change In intersection entering traffic volume: change in level of service: change in calculated vehicle dela3r. change in volume -to -capacity ratio. Average delay is a time quantity which is easy for the general public to relate to; however, it becomes nearly meaningless when LOS F occurs. When LOS F occurs, the volume -to -capacity ratio (v/c) is a more appropriate technique for measuring forecasted project Impact. SR 99/212th Street SW is forecast to experience a minor degradation in operations during the PM peak hour due to the project, although it would operate at LOS F In 1992 with or without the project. If the widening improvements proposed in the Cofte Place 7�-qtftc Sfttdy were implemented. the intersection would operate at LOS E in 2000 according to the Bell -Walker Study. When SR 99 is widened to seven -lanes, as planned, forecasted operations would remain LOS F; however, v/c would be reduced by 10 percent. 90371.50\903715RI The TRANSPO Gmup, Inc. Page 22 Table 4.

Page 23 SR 99/220th Street would operate at about the same volume -to -capacity ratio, with or without the project. LOS F operations would continue in either case. When SR 99 is widened to seven lanes. operations would improve substantially along the corridor, with v/c reduced by almost 15 percent; however, the intersection would continue to operate at or near capacity during the PM peak hour. Operations could be further improved if either dual northbound and southbound left-tum lanes, or exclusive right -turn lanes are included in the planned seven -lane widening project. The design report for the widening project should consider these Intersection enhancement options. Operational benefits must be weighed against impacts to adjacent comer properties. Under the worst -case scenario. v/c in 1992 with the project would be about 1.5 percent higher than v/c In 1992 without the pmJect. No noticeable change in v/c would occur compared to v/c using average trip generation rates. The worst -case scenario does not lead to signifIcant traffic impacts at this intersection. SR 99/224th Street would remain at LOS D when project traffic is added to 1992 baseline PM peak hour volumes. The intersection would improve to LOS C in the PM peak hour with the planned widening of SR 99 to seven lanes. No other improvements or modifications to operations are recommended. 220th Street SW/76th Avenue W is forecast to remain at LOS F in 1992 with or without the addition of project traffic if no improvements are made. Ultimately, a Elve-lane section should be constructed between SR 99 and 76th Avenue W. If this were completed (including five lanes on the west approach to 76th), LOS D operations could result. Under the worst -case trip generation scenario, v/c in 1992 with the project would be about 1.8 percent higher than v/c in 1992 without the project. No noticeable change in v/c would occur compared to v/c using trip generation rates. The worst -case scenario does not lead to significant buffic impacts at this intersection. The worst -case trip generation would not result In noticeable changes in intersection operation (when compared with impacts using average trip generation) at the two intersections which would experience the highest project traffic impacts. It can thus be concluded that impacts would not be noticeably different at = study area Intersection using either average or worst -case trip generation estimates. Since all other locations were analyzed assuming 90371.00\90371RI The TRANSPO Group, Inc. Page 24 average trip generation rates, conclusions reached can be reasonably assumed to reflect results generated under a worst -case analysis. An interim improvement could be constructed at the 220th Street SW/76th Avenue W intersection to improve operating conditions without widening 220th. This would involve restriping the north and south legs of 76th Avenue W to allow for an exclusive left -turn lane and a right/thru lane. The signal phasing could then be revised from split phase to stan- dard phasing to include north/south left -turn and thru phases. Phasing for the east and west legs would remain split. In addition, it is recommended that a right -turn overlap phase be added for westbound right turns. With these improvements completed, LOS D would result for average weekday PM peak hour conditions. 7bese improvements would require that the controller be replaced. If these Improvements were included with the ulti- mate five -lanes along 220th Street SW through the intersection. operations would be better than the LOS D identifted with either improvement. 220th Street SW/66th Avenue would operate at LOS F in 1992 with or without the prrject. Retiming the signal could improve level of service to IDS D/E. 7he City of Mountlake Ten -ace has a pmJect programmed to retime the 220th Street SW signal system from SR 99 to 1-5. 212th Street SW/76th Avenue is forecast to operate at LOS F with or without the project. Project traffic impacts are estimated to increase v/c by about 1.8 percent. If the projects identified in the College Place 7)-aj)7c Shidy were constructed, the intersection is forecast to improve to LOS E in 2000 (according to the College Place Tralflic ShLdy). SR 99/216th Street would experience additional degradation to side -street cir- culation in 1992 during the PM peak hour if no signal were installed. All traffic from 216th Street SW would continue to operate at LOS F with or without the project. Left turns from SR 99 would operate at LOS E. The project adds thru trips on SR 99 to this intersec- tion which would contribute to both eastbound and westbound side -street delays - The TIP identiftes this traffic signal as the top citywide Intersection Improvement priority, to be completed In 199 1. If this occurs prior to the widening of SR 99 to seven lanes, LOS D would occur with or without the project. With SR 99 widened to seven lanes, LOS B would result. These results assume no shift in traffic volume when the signal is installed. Some increase in side street (especially east approach) traffic may occur, as 90371.00\90371RI The TRANSPO Group, Inc. Page 25 SR 99 access becomes easier at this location. However, Increased side street traffic at 216th SW/SR 99 would cause an offsetting decrtase (beneftt) at some other location cur- rently being used to gain SR 99 access. Specifically, 212th and 220th Streets SW may experience minor reductions in traffic due to Implementation of a signal at SR 99/216th Street SW. 220th Street SW/84th Avenue would operate at LOS C in 1992 with or without the project, assuming the =-identified signalization is in place. Without the signal (four- way stop -control), LOS D or better would occur with project traffic. The overall effects would be negligible with or without the project in either case. Signal System Considerations The level -of -service analysis was done in recognition of the traffic signal system which controls progressed traffic flows on 220th Street SW and on SR 99. The system is controlled by the City of Lynnwood. While the indtvidual intersection calculations have incorporated current signal timing patterns, future patterns will undoubtedly be Werent, depending on the actual character of traffic flows. The level of accuracy inherent in the best traffic forecasts is not appropriate to use for future signal timing. 'Ibus, the full -sys- tem. Impact of the change in traffic patterns due to the project cannot be accurately assessed. Project Access ne Nelson Motors new car dealership is proposed to be served by four driveways; two each on SR 99 and 220th Street SW. Due to the raised center channelization on SR 99 at this location, the driveways on SR 99 will be right -in, rIght-out only. These driveways will operate at LOS A during the PM peak hour in 1992 with the project. The two Nelson Motors drtveways on 220th Street SW are proposed to be full access drtveways. The ire aainder of this section deals with driveway operations on 220th Street SW. The easterly Nelson Motors driveway is proposed to be located directly south of the proposed Top Foods easterly driveway, creating a four -legged intersection. Level of service at this intersection was analyzed assuming 70 percent of the Nelson Motors 220th Street SW 90371.00\90371RI The TRANSPO Group, Inc. Page 26 traffic will use this driveway. Under this assumption, traffic leaving Nelson Motors would openate at LOS C. while westbound left -turns from 220th Street SW into Nelson Motors would operate at IA)S A. The worst turning movement at this Intersection would be the southbound left turn z from Top Foods onto 220th Street SW. This movement would operate at 1A)S F if no ad- justments to Top Foods on -site circulation occur. Since Top Foods has four driveways, some adjustment to Internal traffic patterns Is Mcely. For example, southbound left turns from Top Foods onto 220th Street SW at the easterly Top Foods driveway could reassign as either left turns at the westerly Top Foods 220th Street SW drtveway or as right turns from the Top Foods drtveways onto SR 99. The interaction between driveway operations on 220th Street SW and operations at the SR 99/220th Street SW intersection was also assessed. Eastbound queues on 220th Street SW at the SIR 99/220th Street SW Intersection were calculated to average 15 vehicles (375 feet) in the left-tum lane and 10 vehicles (250 feet) in the thru/right-thru lanes during the PM peak hour in 1992 with the project. Since the easterly Nelson Motors and Top Foods driveways are 325 feet west of SR 99, the calculated left-tum queue would interfere with left turns from these driveways onto 220th Street SW about half the time during the PM peak hour. However. since queue length calculations are dependent on sig- nal timing parameters and average vehicle delay, and the average vehicle delay calculations are over-sensittve to small changes in traffic volume within the LOS F range (see level of service for SR 99/220th Street SW), actual future queue lengths can be expected to be sig- nificantly shorter than the calculated queue lengths. Ibis assumes that the planned 220th Street SW signal system timing improvements are implemented, as planned. The westerly Nelson Motors driveway is proposed to be located about 182 feet west of the easterly Nelson Motor's driveway, placing it about 26 feet east of the westerly Top Foods driveway. Level of service at the westerly Nelson Motors and Top Foods driveways was calculated assuming four -legged operation to reflect the close proximity of the two driveways. Operations at the westerly driveways would be somewhat better than at the easterly driveways. The 26-foot offset of the Nelson Motors and Top Foods driveways would result in an increased chance of vehicle conflicts between exiting left turns at the two driveways. How- ever, since the conflicting turning movement volumes would be low, this conflict is not 90371.00\90371RI The TRANSPO Group, Inc. Page 27 anticipated to result In a signifteant hazard. Restriction of turning movements at the west- erly driveways. In an attempt to alleviate this conflict, would only intensify potential prob- lems at the other driveways and possibly increase traffic volumes on local streets by encouraging circuitous traffic patterns. Signalizing either the easterly or westerly Nelson Motors and Top Foods driveways is not considered a viable alternative since the resulting distance between adjacent signals would be less than accepted standards. It is recommended that this location be monitored and If an Inordinate increase in traffic accidents occurs, some form of control, such as signing the Nelson Motors westerly driveway for right -out only, should be considered. Safety Impacts Because the project would contribute additional traffic to the study area intersec- tions. there could be a commensurate increase in the potential for accidents to occur. In most cases, traffic added by the project during peak congestion periods would be small — thus, the potential for increased accident experience attributable to the project would also be small. 7bere would be an increased potential for accidents at all new driveway locations. since new vehicle conflicts would be Introduced. As discussed above, 220th Street SW driveway access operations should be monitored by the city to assure continued safe oper- ation as thru volumes increase. If accident rates are shown to increase, more restrictive driveway operations may be appropriate to reduce vehicle conflict potential. Pedestrian and Bicycle Activity Full curb. gutter, and sidewalks are included along the entire SR 99 and 220th Street SW pmJect frontages. This is a signiftcant enhancement to local pedestrian facilities, however pedestrian activity is expected to remain low in this area. Nelson Motors new car dealership is unlikely to generate noticeable off -site pedes- trian volumes. 90371.00\90371RI The TRANSPO Group, Inc. Page 28 Transit Impacts No noticeable impact to transit is forecasted. As discussed above, the Nelson Motors facility Is an auto -oriented business. Parking A total of 82 customer and employee parking spaces has been identified on the site plan. This is about two spaces per 1,000 gross square feet. No adverse parking impact is expected. 90371.00\90371111 The TRANSPO Group, Inc. Page 29 MITIGATING MEASURES A number of traffic improvements were identified which would generally more than offset identified project impacts and also would relieve ongoing traffic congestion associated with non -project conditions. By location, these include the following: SR 99/212th Street My - Implement the planned TEP improvement to widen SR 99 to seven lanes which would improve operations, with or without the pro- Ject. No project -specific mitigation appears warranted. 0 SR 99/220th Street - Same as above. 0 SR 99/224th Street SW - Same as above. 220th Street SW/76th Avenue - Widen the 220th Street SW approaches to five lanes (ultimate) and/or restripe the 76th Avenue W approaches and re-signahze as described in the analysis which would result in acceptable LOS D operations, with or without the project. If the ultimate five -lane section is pursued, project participation should be based on "fair -share" contributions; if the Interim improvement is Implemented by Top Foods, no further contribu- tion would be necessary. If Top Foods does not construct the Interim Improve- ment, Nelson Motors may be required to fund the Improvement at some level. SR 99/216th Street - Implement the planned TEP improvement to signalize the intersection which would result in LOS D or better operations, with or with- out the project. 220th Street SW/84th Avenue - Implement the planned TIP improvement to signalize the intersection which would result in LOS C operations, with or with- out the project. 220th Street SW RUect Frontage - The eidsting eastbound left -turn lane approaching SR 99 should be extended west with project development, along the project frontage, to provide a continuous left -turn lane for access into/out of the 220 Street project driveways. 'Ibis is currently planned along the Top Foods frontage (north curb) as part of the project mitigation. 90371.00\90371 R1 The TRANSPO Group, Inc. Page 30 Driveway operations along 220th Street should be monitored and if an inordinate increase in traffic accidents occurs, some form of control, such as signing the Nelson Motors westerly driveway for right -out only, should be considered. SR 99 EUect Frontage - The project frontage Improvements should be devel- oped compatible with the TEP-planned widening of SR 99 to seven lanes. It is also recognized that project traMc contributes minor volumes to other local in- tersections, which are planned for improvements in the six -year TIP, and would contribute to the traffic impacts on the coordinated signal systems along SR 99 and 220th Street SW. Table 5 summarizes the recommended mitigation measures. baseline and project traffic volumes, and calculated "fair -share" contributions. Based on the results of this analysis, Nelson Motors' share of planned vicinity transportation improvements is calcu- lated to be $3,658. Nelson Motors has indicated a willingness to contribute $3,700 to the City of Edmonds general transportation improvement fund for the purpose of mitigating project -specific traffic: impacts. Nelson Motors has also proposed to develop project frontages in accordance with planned and recommended roadway improvements. If the 220th Street SW widening project from 9th Avenue S to 84th Avenue W is Implemented, Nelson Motors'"fair share" for the project would be $900. Together, the frontage improvements and monetary mitigation offer will more than offset project -specific transportation system impacts. Table 5.

The project location is shown on Figure 1. Based on the site plan provided to us, we understand that the project will consist of a concrete tilt -up building having a floor area of about 27,000 square feet. Plans include roof top parking and an elevated ramp for access. Building details are not known at this time. However, we expect that perimeter loads may be in the range of 2 to 4 kips per lineal foot. Column loads may be in the range of 50 to 100 kips. We anticipate that the building will be constructed at or near existing grade, requiring only minimal cuts. Once plans have been finalized we should be provided an opportunity to review foundation and earthwork drawings and specifications. At that time we can provide supplementary recommendations, if needed. 2.0 FIELD EXPLORATION AND LABORATORY TESTING Our field exploration was performed on March 27, 1991 with a rubber -tired back -hoe owned and operated by Deeny Construction Company, Inc. Subsurface conditions at the site were explored by excavating six test pits to a maximum depth of 8.5 feet below existing grade. The approximate test pit locations are shown on the Exploration Location Plan, Figure 2. The field exploration was conducted by an engineering geologist from our firm who classified the soil conditions encountered, maintained a log of each test pit, obtained representative soil samples and observed pertinent site features. All soil samples were visually classified in accordance with the Unified Soil Classification system described on Figure 3. The logs of the test pits are included in this report as Figures 4 through 6. Project No. T-1733 April 18,1991 Representative soil samples obtained from the test pits were placed in closed containers and taken to our laboratory for further examination and testing. The moisture content of each sample was measured and is reported on the test pit logs. Grain size analyses were performed on four samples. The results are shown on Figures 7 and 8. 3.0 SITE CONDITIONS 3.1 Surface The property is an irregular shaped, ten sided parcel covering approximately four acres. It is presently a mobile home park with paved streets, utilities, and several small, frame bu-ildings. The site was graded and much of it paved during the development of the mobile home park some years ago - The site has approximately 300 feet and 427 feet of frontage on Pacific Highway (SR 99) and 220th Street SW, respectively. The ground surface slopes very gently from the west to the east. Topographic relief is about eight to ten feet. 3.2 Subsurface Where it was not removed during development of the roads and parking areas, the topsoil consists of loose, brown silty sand with some organic matter, to a depth of one to two feet. In general, gray to tan, medium dense to dense, gravelly sand and gravelly, silty sand underlies, the site to the explored depths. Very dense glacial till soil was encountered at the bottom of one test pit, below the gravelly sand. 3.3 Groundwate No groundwater seepage was encountered in any of the test pits. However, these holes were left open only for a short time. Some changes may occur over time. However, we do not expect long term groundwater will be a significant factor in site development. 4.0 DISCUSSION AND RECOMMENDATTONS 4.1 General Based on our study, it is our opinion that the site can be developed as planned. Our recommendations should be incorporated into design and construction of the project. Page No. 2 PrOject NO. T-1733 April 18,1991 Our study indicates that the native soils underlying the site consist of medium dense to dense gravelly sand and silty gravelly sand overlying dense to very dense glacial till soils. Wese materials Mrt- The Lynnwood Honda dealership building may be constructed Vg���§2rqad f92� foundations placed on competent native soils or on structural fill. in Ile following sections of this report present more detailed recommendations pertaining to the geotechnical aspects of developing this site. 4.2 S read Foundations .L_ The proposed building may be supported on conventional spread footing foundations bearing on the dense, native gravelly sand, or on structural fill placed over competent soils. Footings may be proportioned for maximum bearing stresses of 3000 pounds per square foot, considering both dead and live loads. When wind or seismic loads are included, a one-third increase is permissible. Continuous wall footings should be at least 12 inches wide and isolated column footings at least 18 inches square. Footings exposed to the weather should bear at least 18 inches below adjacent outside final grades. All foundations should be provided with reinforcement in accordance with structural requirements. 43 Ground Floors Ground floors may be framed over a- crawl space or constructed as slab -on -grade. �jlab-qn ra q ,goors ing bSA,4pp Z" _pTtq4 on the dense native soils or on structural fill place on competent, native soils. To provide a capilla ry break, we recommend placing at least four inches of free -draining fill, such as pea gravel, beneath the slabs. In areas where moisture is undesirable, a plastic barrier at least ten mils thick should be placed on the gravel. An inch or two of sand may be used to protect the membrane during construction. 4.4 Lateml—Foundation Loads Lateral loads on foundations due to backfill stresses, wind, or seismic loads may be resisted by passive soil stresses on the sides of footings and foundation walls, and by friction on the base of foundations. We recommend estimating passive resistances based on an equivalent fluid weight of 350 pounds per cubic foot. This value assumes that the footing concrete is poured against "neat" excavations or that the backfill is compacted to at least 90 percent of its ASTM D 1557 maximum dry density. Page No. 3 Project No. T-1733 April 18,1991 The friction on the base of foundations should not exceed 40 percent of the foundation dead load. 4.5 Permanent !nine and Foundation Walls Based on the site plan, it does not appear that retaining walls will be needed on the project. However if needed, retaining walls including basement or dock walls, should be designed to resist lateral earth pressures imposed by the soils retained by these structures. Walls that are designed to yield an amount equal to at least 0.002 times the wall height can be designed to resist the lateral earth pressure imposed by an equivalent fluid with a unit weight of 35 pounds per cubic foot. If walls are to be restrained at the top from free movement, a uniform pressure of 100 pounds per square foot should be added to the pressure exerted by the equivalent fluid weight. It is assumed that no hydrostatic pressures will act behind the walls and that no surcharge slopes or- loads will be placed above the walls. If surcharges are to be applied, they should be added to the above lateral pressures. Retaining and foundation walls should be backfilled with compacted free -draining granular soils containing no organics. The backfill material should meet the criteria for soil's imported for use as structural fill, as described in the Site Preparation and Grading section of this report. The purpose for using a free -draining, granular backfill is to assure that the design pressures on the retaining walls are not exceeded because of a build-up of hydrostatic pressure behind the walls. Perforated Ri�pe drains shoul4 IL q!�Atjhe 'll iehin the -basv thq wall footi rainin backfi walls. 'Mese pipes should drain to the storm drain syst em. 4.6 ExcavatLon and Slopes We do not anticipate that any significant steep cuts will be required to create site grades. However, should excavation slopes become necessary, they should be constructed in conformance with the limits specified in local, state, and national government safety regulations. Temporary cuts up to a height of four feet may be made vertical. For slopes having a height greater than four feet, temporary cuts in the dense, native sandy soils should have an inclination no steeper than 1:1 (Horizontal:Vertical). All permanent cut or fill slopes should be made no steeper than 2:1. Water should not be allowed to flow uncontrolled over the top of any slopes. All permanently exposed slopes should be seeded with an appropriate species of vegetation to reduce erosion. Page No. 4 4.7 Drainaee Project NO. T-1733 April 18,1991 We recommend the use of drains at the base'of all foundation -and retainin walls. The drains pja� should drain to the storm drain system. The footing drains should be surrounded by at least_lk i - The pea gravel should be wrapped with woven geotextile filter fabric. Roof drains sho Id se aratelY tightlined to the storm drains. In areas adjacent to the building final site grades should be sloped away from the building. 4.8 Pavement Access roads and driveways may be supported on recompacted inorganic native soils, or on structural fill. Where structural fill is required, the upper twelve inches of subgrade soils should be compacted to at least 95 percent of its ASTM D-1557 maximum dry density. Below the top foot, a relative compaction effort of 90 percent is adequate. Regardless of the compaction effort used or the results obtained, all subgrade areas should be in a stable, non -Yielding condition prior to paving. We anticipate that little if any fill will be required to achieve the desired elevation for the planned paved areas. However, any fill needed should meet the requirements for structural fill presented in the Site Preparation and Grading section of this report. The allowable thickness of the fill layer will depend on the material used, compaction equipment and the number of passes made to compact the layer. In no case should the layers exceed twelve inches in loose thickness. The use of geotextiles and/or crushed rock may help expedite subgrade preparation where wet or yielding soils are present. We recommend using Mirafi 500Y, or a woven fabric with equivalent strength and permeability. In most instances, twelve inches of granular fill will stabilize the subgrade except for very soft areas where additional fill could be required. The subgrade should be evaluated by qualified technical personnel after the site is stripped and cut to grade. The pavement section for light traffic areas should consist of two inches of asphalt surfacing over either four inches of crushed rock base (CRB) or three inches of asphalt treated base (ATB). For heavily loaded areas, such as main driveways and areas with truck traffic, we recommend three inches of asphalt surfacing over six inches of crushed rock base or four inches of asphalt treated base. Pavements should be placed over an adequately prepared subgrade as discussed above. 4.9 Site Preparation and Grading Building and pavement areas should be stripped of any vegetation, topsoil, loose surficial soils and any other deleterious material. We recommend that any soils to be imported for use as structural fill be evaluated by Terra Associates, Inc. before they are brought onto the site. For import fills, we suggest that no more than five percent of the soil fraction passing the 3/4-inch screen should be finer than the No. 200 sieve. Page No. 5 Project No. T-1733 April 18,1991 Native soils are granulate in nature and should be generally suitable for use as structural fill except under wet conditions. All structural fill should be placed in horizontal layers and compacted to a density equal to or greater than 95 percent relative compaction as determined by ASTM Test Designation D-1557 (Modified Proctor). The fiff material should be placed at or near the optimum moisture content. The individual fill layers should not exceed twelve inches in loose thickness. 5.0 ADDMONALSERvICES We recommend that Terra Associates, Inc. be provided the opportunity to review the final design and the earthwork specifications in order to verify that our recommendations have been properly interpreted and implemented in the project design. To observe compliance with the design concepts, specifications and recommendations, and to allow expedient design changes in the event subsurface conditions differ from those anticipated, we also rec I ommend that Terra Associates, Inc. be retained to provide geotechnical services during construction. These services should include: 1) observing all earthwork operations and the placement and compaction of any structural fill that may be required; 2) observing all footing and slab areas Prior to forming and concrete placement; 3) Performing field densibr tests on compacted fills and backfills; 4) observing and testing the subgrade under pavement. 6.0 LIMITATIONS The analyses and recommendations submi tted herein are based on data from test pits. However, actual subsurface conditions may differ from those observed in the test pits. The nature and extent of any such variations may not become evident until construction. If variations are observed during construction, Terra Associates, Inc. should be requested to evaluate the actual site conditions and review the recommendations in this report prior to proceeding with construction. This report has been prepared specifically for this project. It is the property of Terra Associates and is intended for the exclusive use of Nelson Motors, Inc. and its representatives. We do not guarantee project performance in any respect, only that our work meets normal standards of professional care. No other warranty, expressed or implied, is provided.

C.S.3101 Nelson Motors, Inc., Second Traffic Analysis Review City File No. V-3-91 This letter is in response to the developer's request for our preliminary comments on his proposed development's revised traffic analysis. This revised traffic analysis was requested by WSDOT in our last letter dated March 18, 1991 to Mr. Ed Somers of the City's Planning Department. The site of this proposed development is located in the southwest quadrant of the SR-99/220th Street S.W. intersection. The State's preliminary comments on the revised traffic analysis for this proposed development are as follows: The traffic consultant has determined that the existing LOS at several SR-99 intersections will be worse when this proposed development is occupied in 1992. However, with the exception of one SR-99 intersection, 212th Street.. S.W., these impacted State highway intersections LOS will be improved from their existing LOS in 1992 when SR-99 is widened to seven lanes and a new signal is installed at the 216th Street S.W. intersection. The City of Lynnwood is the lead agency f or a three stage SR-99 improvement project that is currently being designed by the City. The first stage of this project is scheduled for construction in 1992. This project will consist of widening SR-99 to seven lanes from 244th Street S.W. to 216th Street S.W. and installing a signal at.the SR-99/216th Street S.W. intersection. With these improvements in place prior to this development being occupied, the traffic impacts from this development will be sufficiently mitigated. The second stage of this SR-99 improvement project is scheduled for construction in 1993. It will consist of widening SR-99 to seven lanes from 216th Street S.W. to 196th or 164th Street S.W.. The traffic study shows that the 0 0 June 27, 1991 Gordon Hyde Page 2 SR-99/212th Street S.W. intersection has an existing LOS of "Ell and will drop to an 'IF" with or without this development's traffic in 1992. With the planned SR-99 improvements (second stage project) in place at this intersection in 1993 the LOS will still be an 'IF"' but the average delay of the existing signal will be improved to a better LOS 'IF". The developer has proposed to contribute his proportionate share towards the City of Edmonds general transportation improvement fund for the purpose of mitigating his traffic impacts to SR-99 and City street intersections. we concur with this form of mitigation as being sufficient for this development's impacts to the impacted SR-99 intersections. As we stated in our previous letter, we request that the developer have his consultant analyze the I-5/220th Street S.W. ramp intersections. This development sends 25% of its peak hour traffic to this interchange. When we have reviewed the traffic analysis for the ramp intersections we can determine if this development should mitigate it's traffic impacts at this interchange. We concur with the consultant's recommendation that the developer improve his site's SR-99 frontage in accordance to the planned SR-99 Stage One widening project. WSDOT would appreciate an opportunity to review the surfacing depths the developer plans to put in SR-99 since WSDOT is responsible for maintaining the SR-99 surfacing. Thank you for the opportunity to offer our preliminary comment's on this proposal. once we have' reviewed the traffic analysis for the I-5/220th Street S.W. ramp intersections and the, SR-99 surfacing depths for this development we can complete our review of this proposal's State highway impacts.

NALIGHTEN MAYOR PETER E. HAHN DIRECTOR Please send a copy of the April 10, 1991 Traffic Impact Analysis for Nelson Motors to: Washington State Department of Transportation District 1 15325 S.E. 30th Pl. Bellevue, WA 98007 Attention: Ed Giraud Because of the proposal fronts on state routes, Washington State Department of Transportation (WSDOT) needs to review impacts. Apparently, they have only received the January 23, 1991 report. On May 15, 1991, Mr. Erik Nelson transmitted a letter requesting that I provide you with supporting figures for the requested $8,500 traffic mitigation for your review. TRANSPO has completed a very thorough traffic impact analysis for the Top Foods project across the street from Mr. Nelson's proposed project, in which the mitigation proposal for their impact of 428 new and diverted trips is approximately $103,000 or $240.66 per trip. In that scenario, frontage improvements of both Highway 99 and 220th St. S.W. are considered a condition of development. Applying that per trip contribution to the Nelson trip generation of 66 new trips produces a mitigation total of $15,883, exclusive of frontage improvements. Based on that reasoning, the $8,500 request is very conservative. How can a traffic engineer analyze two projects within the same area of influence and come up with two such substantially differing impact mitigations? I would further point out to Mr. Nelson that the traffic report, as submitted, suggests appropriate trip generation numbers based upon an unaccepted standard of "number of service bays". If one were to take 0 Incorporated August 11, 1890 Sister Cities International — Hekinan, Japan Doug Coxon The TRANSPO Group May 22, 1991 Page 2 the more traditional approach of trip generation based upon square footage of building area or acreage of development, the resultant trip generation figures go from the 66 as proposed in TRANSPO's report to the neighborhood of 107 to 118 p.m. peak hour trips. These generation figures would result in numbers nearly triple the requested mitigation. I remain, Sincerely yours, ?GRDON C.

We acknowledge the request that Nelson Motors Mitigation offer be $8500-00. in addition your letter acknowledges acceptance and agreement by you that Transpo's numbers are a true representation of the facts. Based on these facts we feel our proposed mitigation, as calculated by Transpo, is appropriate. We have also contacted Scott Snyder, Edmonds City Attorney who confirmed that the City can only ask for the actual cost of the impacts for mitigation. If the City disagrees with the proposed mitigation the City has the burden of proof to prove new substantial and competent numbers supporting the requested mitigation amount. Nelson Motors Inc. requests that the City of Edmonds the proposed $3700.00 amount or that substantial and competent numbers supporting the requested $8500-000 available for Transpos review.

MENOWNED, A� --- Im 0 Date: December 29, 1999 To: File ADB-99-221 Street File 22020 Hwy 99 From: Steve Bullock 49P Senior Planner Subject: ADMINISTRATIVE DESIGN REVIEW FREESTANDING SIGN REPLACEMENT. APPROVAL FOR A Identity Signs is proposing to replace I existing freestanding sign on Highway 99 with a new freestanding sign. The existing sign is mounted between to poles and has a sign area of approximately 69 square feet. Although the sign is fairly open at the bottom, it is 15 feet wide at the top. The proposed sign is an eight foot wide pylon sign. It has less than 64 square feet and is using the same colors as the original sign, blue and white. Review of the application has deemed it complete. Because the proposed sign is smaller in area than the existing sign, and because it is using the same colors as the existing sign and because the design of the proposed sign is consistant with the development of the site, I am administratively approving the Design Review element of this project subject to the applicants receiving a Building Permit for its installation and the Engineering Division's approval of the pylon design as it pertains to sight distance and vehicles safely exiting the site.
