a'07 1 2 0 15 MEMORANDUM aE°i4!'*,1 Cr G;f: I I:, IIAIIFIPI ,PO,J 13,P, 1p LD 40 1 4f)S_()6 Date: July 20, 2015 TG: 15033.00 To: Bertrand Hauss, City of Edmonds From: Mike Swenson and Alex Atchison, Transpo Group cc: Glenn Goodman, Merlone Geier Partners Subject: Edmond Retail Pad — Traffic Impact Analysis This memorandum summarizes potential traffic -related impacts associated with the proposed retail development located at the existing Top Food & Drug shopping center in Edmonds, Washington. . Based on the overall trip generation associated with the project and review of the City TIA guidelines, the scope of the analysis was limited to a Level I analysis. The scope of a Level I analysis includes estimate of the anticipated trip generation for the project and a review of the level of service (LOS) impacts at the 220th Street SW and SR 99 access points. Project Description The proposed project includes approximately 6,000 square -feet of new retail space located in the southern end of the existing Top Food & Drug shopping center at the corner of Highway 99 and 220th Street SW in Edmonds, Washington. Figure 1 illustrates the project site and surrounding vicinity. A site plan showing the location of the retail pad is included as Figure 2. 11730 118th Avenue N.E., Suite 600, Kirkland, WA 98034 1 425.821.3665 1 tranSpo , I Com ke"', �' ° VSa':SV dot N f'hi0 VII'K"' FS„VIV i Y)OD A , I':dRiIJ'G „ Nf,)� A, 'J",@;JPNW "i VRISIf;V S W Study Scope The analysis includes an evaluation of the trip generation and LOS at the site access driveways for the existing and future conditions. As shown on the site plan, two driveways are located on both SR 99 and 220th Street SW. Based on the trip generation increases associated with the project and the City of Edmonds TIA guidelines, no analysis of off-site intersections was required and the analysis is limited to an evaluation of the driveway operations only. Future with -project conditions are evaluated by adding site -generation traffic to future without - project conditions. Future with -project conditions are then compared to future without -project conditions to identify the relative impacts of the proposed project on the surrounding transportation system. This study evaluates the weekday PM peak period (4:00 to 6:00 p.m.) driveway operations of the site. A horizon year of 2016 was assumed for the analysis based on the anticipated completion of the project. Roadway Network The project is located in the existing Top Food & Drug shopping center at the corner of Highway 99 and 220th Street SW in Edmonds, Washington, Highway 99 is a seven -lane roadway classified as a principal arterial. 2201h Street SW is a five -lane roadway currently classified as a minor arterial. bf' 2 Traffic Volumes Existing turning movement counts at the existing driveways were conducted in January 2015. The intersection turning movement count worksheets are provided in Attachment A. Existing weekday PM peak hour traffic volumes at the four existing site driveways are summarized in Figure 3. Forecast (2016) without -project traffic volumes were forecast by applying a 1.5 percent annual growth rate in the project vicinity, per discussion with City staff. Figure 3 also shows 2016 without - project traffic volumes. Project Trip Generation Trip generation estimates are summarized in Table 1. Estimates for project -generated vehicle trips were calculated using average peak hour trip rates for a Shopping Center (Land Use No. 820) published by the Institute of Transportation Engineers (ITE) in Trip Generation (9th Edition, 2012). As described previously, the proposed project would construct approximately 6,000 square -feet of new retail space. Forecast daily and weekday PM peak hour trips are summarized in Table 1. Table 1.

As shown in Table 1, the proposed project would, generate approximately 256 daily trips. During the weekday PM peak hour, the project would generate approximately 14 new primary trips (non - pass -by trips) with 7 inbound and 7 outbound. The analysis did not account for trips internal to the existing shopping center in order to provide a conservative estimate of the future driveway operations. Project Trip Distribution & Assignment Project trips were distribute6to the network based on the existing traffic counts at the individual driveways shown in Figure 4. Weekday PM peak hour project trips were assigned to the roadway network based on the distribution patterns and are shown in Figure 3.

Traffic operations were evaluated based on the procedures identified in the Highway Capacity Manual (2010), and evaluated using Synchro version 8.0. At signalized and unsignalized intersections, LOS is measured in average control delay per vehicle and is reported using the intersection delay. Traffic operations for an intersection can be described alphabetically with a range of levels of service (LOS A through F), with LOS A indicating free-flowing traffic and LOS F indicating extreme congestion and long vehicle delays. Attachment B contains a detailed explanation of LOS criteria and definitions. Table 2 summarizes the weekday PM peak hour LOS at the existing site driveways for existing and future conditions. In addition to operations at the driveways, operations at the worst operating movement are reported for each location. Detailed LOS worksheets are included in Attachment C.

The project is not expected to increase delay at the site access driveways and LOS is expected to be the same under future -with project conditions as under future without -project conditions. Impact Fee Calculations To mitigate transportation impacts of the proposal on the surrounding transportation system, the developer would be required to pay traffic impact fees to the City of Edmonds. Traffic impact fees are set forth in the 2009 Impact Fee Rate Table of the City of Edmonds Traffic Impact Analysis Requirements, and are estimated to be $8,040, as calculated in Table 3. The City's impact fee analysis takes into account new off-site and pass -by trips. In addition to pass -by trips, this project will likely also generate internal trips within the exiting development given its proximity to the existing Top Food & Drugs grocery store. Using methodologies set from the of Transportation Engineers' Trip Generation (9th Edition) and Trip Generation Handbook (3rd Edition), the proposed project is expected to have 9 percent of the trips internally captured Accounting for this internalization of project trips, transportation impact fees for the City of Edmonds are estimate to be $7,316. These fees will be reviewed and finalized by the City of Edmonds. Table 3.

Impact fee rates are based on the 2009 Impact Fee Rate Table (City of Edmonds, 2010),. Summary & Conclusions • The project includes the construction of approximately 6,000 square -feet of new retail space is proposed at the existing Top Food & Drug shopping center at the corner of Highway 99 and 2201h Street S.W. in Edmonds, Washington. • The proposed project would generate a total of 14 new primary (non -pass -by) weekday PM peak hour trips (7 inbound and 7 outbound). • Site access driveways are expected to operate at LOS C or better under future 2016 with -project conditions. This represents no change in the LOS and only a minor increase in the delay for any one movement. • Transportation impact fees for the City of Edmonds are estimated to be $7,316 after accounting for internally captured trips. This is a preliminary estimate of traffic impact fees and the final fees will be calculated by the City of Edmonds.

Control delay quantifies the increase in travel time that a vehicle experiences due to the traffic signal control as well as provides a surrogate measure for driver discomfort and fuel consumption. Signalized intersection LOS is stated in terms of average control delay per vehicle (in seconds) during a specified time period (e.g., weekday PM peak hour). Control delay is a complex measure based on many variables, including signal phasing and coordination (i.e., progression of movements through the intersection and along the corridor), signal cycle length, and traffic volumes with respect to intersection capacity and resulting queues. Table 1 summarizes the LOS criteria for signalized intersections, as described in the Highway Capacity Manua! 2010 (Transportation Research Board, 2010). Table 1. Level of Service Criteria for Signalized Intersections Average Control Delay Level of Service (seconds/vehicle) General Description A <10 Free Flow >10-20 Stable Flow (slight delays) C >20 — 35 Stable flow (acceptable delays) D >35 — 55 Approaching unstable flow (tolerable delay, occasionally wait through more than one signal cycle before proceeding) E >55 — 80 Unstable flow (intolerable delay) F' >80 Forced flow (congested and queues fail to clear) Source: Highway Capacity Manual 2010, Transportation Research Board, 2010, 1, If the volume -to -capacity (v/c) ratio for a lane group exceeds 1.0 LOS F is assigned to the individual lane group LOS for overall approach or intersection is determined solely by the control delay, Unsignalized intersection LOS criteria can be further reduced into two intersection types: all -way stop and two-way stop control. All -way stop control intersection LOS is expressed in terms of the weighted average control delay of the overall intersection or by approach. Two-way stop -controlled intersection LOS is defined in terms of the average control delay for each minor -street movement (or shared movement) as well as major -street left -turns. This approach is because major -street through vehicles are assumed to experience zero delay, a weighted average of all movements results in very low overall average delay, and this calculated low delay could mask deficiencies of minor movements. Table 2 shows LOS criteria for unsignalized intersections. Table 2.

If the volume -to- capacity (v/c) ratio exceeds 1.0, LOS F is assigned an individual lane group for all unsignalized intersections, or minor street approach at two-way stop -controlled intersections.
