Miles, Assistant Planner Recommendation: Approval with conditions Request The applicants for the upcoming Interurban Retail site (13038 Interurban Avenue S) have submitted a request for an administrative parking variance per TMC 18.56.140 with an attached traffic study. The applicants have proposed two uses within the building, fast food and general retail. The fast food will have a total usable floor area of 3066 square feet. General retail will have a total usable floor area of 2,636 square feet. Under Figure 18 -7 of the TMC fast food is required to have a parking ratio of one stall for every 50 square feet of usable floor area. General retail, located outside of the TUC, is required to 2.5 for every 1,000 square feet of usable floor area. The total number of parking stalls required for the proposed project is 63 stalls. The applicant has requested to reduce the total number of required parking stalls from 63 to 58 stalls. A reduction of five stalls, which would be 7.9 percent of the required parking stalls. Steven M Mullet, Mayor 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206 - 431 -3670 • Fax: 206 - 431 -3665 Review Criteria A. All shared parking strategies are explored. TMC 18.56.140 (B) states the criteria that will be used to evaluate administrative variance from parking standards. The project site is bordered by three commercial businesses, Jack in the Box, Husky Trucking, and the Gateway Office Complex. Parking on the Jack in the Box site is limited, additionally parking in the Jack in the Box parking lot would require patrons of the applicant's building to cross a major drive path. The Husky Trucking property is an active truck yard and for safety reasons a shared parking agreement was not explored. The applicant did approach the owners' of the Gateway Office Complex with regards to obtaining a shared parking agreement. In an email dated, September 9, 2004, the applicant noted that the owners' of the Gateway Office Complex were note interested in sharing excess parking. B. On site parking and ride opportunities are fully explored. Mass transit is available along Interurban Avenue. Customers and not the employees on the site will generate most of the parking demand for the building. Thus, implementing a park and ride program for employees on the site would not significantly reduce the total number of parking stalls needed. C. The site is in compliance with the City's commute trip reduction ordinance, or it not and affected employer as defined by the City's ordinance, agrees to become affected. The project is not subject to the requirements of the City's CTR program. However, granting this administrative parking variance will required that the site participate in the City's CTR program. D. The site is at least 300 feet away from a single- family residential zone There is no single - family residential zone within 300 -feet of the subject property. E. A report is submitted providing a basis for less parking and mitigation necessary to offset any negative effects As part of this project the applicant submitted a Traffic Impact Analysis (TIA) prepared by The Transpo Group, dated October of 2004. According to the TIA, the peak hour will require that 42 parking stalls be available. As previously noted the applicant will be providing a total of 58 parking stalls. Conclusion Based upon the information presented to the City, the reduction of parking on the site by 7.9 percent is warranted. The applicant has provided a parking review, which demonstrates that sufficient parking will be available on the site. The applicant did attempt to obtain a shared parking agreement with an adjacent property owner and one could not be obtained. Staff's Recommendation The administrative parking variance should be granted subject to the following conditions: 1. The site is now subject to the City's CTR program. 2. The decision to grant the administrative parking variance is based upon the following usable square footage calculations provided to the City, 2929 square feet devoted to fast food and 2371 square feet devoted to general retail. If the uses on the site change to uses that trigger and increase in parking demand, this administrative variance is null and void. Additionally, if there is an increase in usable square footage on the site this administrative parking vari ance is null and void.

We previously used the 90% as dictated in the guidance. But it appears that we may have a disconnect on the treatment of this issue... Would we be able to approach the Complementary Parking issue by saying that a portion of the Starbucks, specifically the drive through area, is 'a portion of the development that functions differently than the primary land use without creating additional parking needs for the primary traffic generator'? It's clear that the drive through portion will not create additional parking needs. If anything, it will eliminate parking needs. Do you agree on this? If so, here are my latest calculations on the Parking Requirements for Interurban Retail: If this is the case then we will need to relocate the fire hydrant so we don't kill any parking stalls.

TMC 18.56.070 (D) notes that "complementary use is a portion of the development that functions differently than the primary land use without creating additional parking needs for the primary traffic generator. Up to 10 percent of the usable floor are of a building or facility may be occupied by a complementary use without providing parking spaces in addition to the number of spaces for the principal use. Examples of complementary uses include pharmacies in hospitals or medical offices, food courts in restaurants in a shopping center or retail establishments." This would not be considered a food court not were in be complementary to any retail on the site since the food establishments have a greater square footage than the retail on the site. Additionally, the Starbucks and Quiznos are destinations. Can you provide me the actual usable floor area of the building? Brandon J.

"Cory Shelest" <Cory@GramorWa.com> "Brandon Miles" <bmiles @ci.tukwila.wa.us> 9/9/04 11:55AM RE: Interurban Retail To answer your question - no, unfortunately, it will not be possible to get a shared parking agreement with Gateway. Despite the fact that there are ample parking spaces available in their corporate center, they've made it clear that they do not want to share excess parking. To be honest though, I think this approach will easier on all parties in the long run. There might be another way to look at this however... many of the end users to our center will be drawn from Gateway. And, many of these customers will come by foot. There are 8000 estimated office /corporate /service workers within a 1 mile radius of this site. Not all of them will come by foot, but I would insist that a lot of them ultimately will. As an aside, I would like to point out the worn down pedestrian foot path that diagonally intersects the permit land adjacent to our site (it creates a direct line from Gateway to Jack in the Box)! The Gateway folks have expressed excitement with our center; it will be a good complement to the corporate center as it will add a few different service offerings, and more importantly, a few other food establishments in the area. Furthermore, and while I'm on the topic, the addition of the drive through for Starbucks eliminates the need for some parking. Customer demand for the efficient and convenient drive through offering has decreased overall parking demand as seen in other Starbucks locations. With the drive through in place that has a capacity of 11+ cars, it's not felt that Starbucks will require an additional 34 stalls of parking to efficiently operate their business in our center (1710 sf @ 1 stall per 50 sf). Their total capacity will be 45 spaces /stalls! This will be will be the busiest Starbucks in the world if they can keep this capacity maximized! J. If anything, we feel that the implementation of the drive through will free up parking spaces for the center. Let me know if there is anything else that I can provide.

The proposed project is a redevelopment of a former Unocal fuel station and Circle K convenience store into a single building multi -tenant retail project totaling 5,700 sf. There are proposed uses /tenants with this project: Starbucks (1700 sf), Quiznos (1364 sf), and an additional 2638 sf that will be used for traditional retail. See Exhibit A: Site Plan We would like to pursue both Complimentary Parking and Administrative Variance with this proposed center. In line with the Special Permission Director Application it is important to note the following: a. All shared parking strategies have been explored b. On -site park and ride opportunities are not possible c. The site is in compliance with the City's commute trip reduction ordinance d. The site is at least 300 feet away from a single family residence zone e. A report has been provided which provides a basis for less parking (see Transportation Impact Analysis, Interurban Retail, July 2004 The Transpo Group) Parking We acknowledge the criticality of the parking spaces on the proposed development. Our current calculations in this project are as follows: 5 � '\.5 S Square feet Parking Requirent G t Retail — Fast food (20/1000s0 3,064 fills tD Retail — Traditional (2.5/1000sf) 2,638 7 stalls 62 stalls I ( Administrative variance of 10% � 3 \ 6 stalls Total 56 stalls 1 61 stalls applied to estimated usable area of 90% (Complementary Parking TMC 18.56070(D)) Note: parking calcs include the assumption that Seattle City light permit land will be utilized Given the assumptions above, with the utilization of Complementary Parking and Administrative variance, our required number of stalls is reduced to 56. Our current site plan provides for 58 stalls of parking. Therefore, we have provided 2 stalls in excess. Please note that we typically like to avoid the implementation of `compact' parking stalls and would like to work with the city in determination of this treatment.

The purpose of this analysis is to identify any potential traffic - related impacts the proposed project would have on the roadway network in the site vicinity and to recommend mitigation measures, as necessary, to mitigate those impacts. Project Description The proposed project is located mid -block between the intersections of Gateway Drive S and 48th Avenue S on Interurban Avenue S. A site vicinity map is included as Figure 1. The site is currently vacant, as a gas station and convenience market formerly located on -site has been demolished. Access to the site will be consistent with the existing configuration, with full access to existing private driveways located on both the east and west of the site which ultimately access Interurban Avenue S. Full access is currently permitted at the intersections with Interurban Avenue. The project would consist of a single building, which would include an approximately 1,700 square foot (sf) Starbucks Coffee shop with drive -thru window, a 1,365 sf fast -food restaurant without drive -thru (identified as a Quiznos), and approximately 2,650 sf of specialty retail space. Figure 2 includes the site plan used as the basis for this analysis. Full buildout is anticipated by 2005. However, to be consistent with other studies conducted in the City of Tukwila, and as directed by City staff, a 2010 horizon year was used for this study. Study Approach In order to meet the study's objectives, the study area and scope were coordinated in advance with review staff from the City of Tukwila. Four signalized intersections near the project site were selected for analyses during the PM peak hour. In addition, to satisfy City of Tukwila Municipal Code (TMC) 9.48- Transportation Concurrency Standards and Impact Fees, four additional signalized intersections were selected for PM peak analysis south of Interstate 5 (I -5) to allow for the analysis of the Interurban Avenue arterial unit. This arterial unit is defined by the TMC as between I -5 and Interstate 405 (I -405). The four nearest intersections were identified due to potential impacts based on overall distribution of project trips. The selected arterial unit was selected as it will be impacted by five or more peak hour trips. In addition to intersection and arterial levels of service, the scope of the analysis includes a review of traffic safety and impact fee calculation.

The analysis of existing and future without- project traffic conditions provides a frame of reference when evaluating potential project impacts. Project impacts are measured by comparing the difference in area operations between the with- and without- project scenarios. Roadway Network Existing roadway and non - motorized characteristics for the immediate study area are described below. Interurban Avenue S is a five -lane roadway that runs southeast - northwest in the project vicinity. Between Interstate 5 and Interstate 405, Interurban Avenue S is designated as a principal arterial, while to the north of I -5 adjacent to the project site, it is designated as a minor arterial. Major intersections along Interurban Avenue S are signalized. Sidewalks exist on the east side of the roadway in the immediate area of the project, and intermittently on the west side. The posted speed limit is 35 mph. S 133rd Street /Gateway Drive S is designated as a minor arterial to the west of Interurban Avenue S, and a local roadway to the east. It consists of four lanes to the east of Interurban Avenue S (Gateway Drive S), and two lanes to the west. Sidewalks exist on the south side of the roadway, and intermittently on the north side. The posted speed is 30 mph to the west of Interurban Avenue S, and 25 mph to the east. 48th Avenue S is a local roadway located to the south of the project site. 48th Avenue S is a two -lane roadway with sidewalks located on the east side of the street, and intermittently on the west side. A traffic signal controls its intersection with Interurban Avenue S. The posted speed limit is 25 mph. 52nd Avenue S /56th Avenue S is a two -lane collector arterial to the south of Interurban Avenue S (52nd Avenue S), and a local roadway to the north (56th Avenue S). A traffic signal controls its intersection with Interurban Avenue S. Sidewalks exist on the west side of the roadway. The posted speed limit is 25 mph. Existing and Future Traffic Volumes Existing weekday PM peak hour volumes were collected at the study area intersections in May and June 2004. The existing PM peak hour traffic volumes are summarized in Figure 3. Based on direction from City Staff, and to remain consistent with other studies conducted in the area, a 1.5- percent annual growth rate was applied to the existing volumes. In addition, City Staff indicated that traffic volumes from the planned Southcenter Mall expansion project, currently undergoing environmental impact review, should be included in the future 2010 traffic volumes. Since the Southcenter Mall expansion has not been approved, the inclusion of this traffic results in a conservative estimate of the future forecast volumes. The combination of the background traffic growth rate and this pipeline project account for The Transpo Group 104209.00': .04209r1.doc 4 Interurban Retail, Tukwila, WA DRAFT July 2004 future traffic growth in the study area.

No projects were identified that would directly impact the operations at study intersections. However, one project was identified on Interurban Avenue that will improve general transportation facilities, but not increase roadway capacity. This project would construct curb, gutter, sidewalk, illumination, and landscaping improvements on Interurban Avenue between S 143rd Street and Fort Dent Way. The design phase of the project was scheduled to begin in early 2004, with no completion date identified. No other projects were identified at study intersections or along the studied arterial unit. Intersection Operations A level of service (LOS) analysis was conducted for the study area intersections for the weekday PM peak hour. The signalized intersections were analyzed using Synchro 5.0. This software program is based on methodologies presented in the Highway Capacity Manual (HCM) (Transportation Research Board, 2000 Edition). LOS values range from LOS A, which indicates good operating conditions with little or no delay, to LOS F, which indicates extreme congestion and long vehicle delays. LOS is measure in terms of total average intersection delay for signalized intersections, and total vehicle delay by lane group for unsignalized intersections. A more detailed explanation of LOS criteria is provided in Appendix A. Table 1 summarizes both existing and future without- project, weekday PM peak hour LOS, for the eight study area intersections. The LOS worksheets are included in Appendix B. The signal timing information used for the intersection analysis was based on information obtained from the City of Tukwila. Signal timing information from existing conditions was optimized within parameters from the timing information and held constant for all future operating analyses.

The two intersections on the far southern end of the Interurban Avenue S arterial segment currently have the highest amount of delay of the study intersections. The Interurban Avenue S /Fort Dent Way intersection currently operates at LOS D, but degrades to LOS E in 2010 baseline conditions. The Interurban Avenue S /Southcenter Boulevard intersection currently operates at LOS F, and is anticipated to continue to do so in the future, as no improvements are planned for this intersection by the City. Arterial Operations To satisfy TMC 9.48, an arterial LOS arterial analysis was conducted for the Interurban Avenue S arterial unit. TMC 9.48.070 defines the Interurban Avenue S arterial unit as being between I - and I -405, and states that LOS E or better shall be maintained for this arterial Consistent with the Highway Capacity Manual, arterial level of service is reported in a range from LOS A to LOS F (LOS A indicating free flow and LOS F indicating failing conditions) and is a function of average travel speed (miles per hour) along the arterial. Travel speed takes into account driving time between intersections, and the through movement delay Mj� encountered at all signalized intersections along the segment. Table 2 shows the resulting t C LOS for the Interurban Avenue arterial segment. The LOS is based on an arterial t ✓ � fr 0 classification of Interurban Avenue S as an arterial Class III facility.

Based on these results, the arterial segment is currently operating, and is anticipated to continue operating within the City's LOS standard by 2010 without the proposed project. Traffic Safety The purpose of this section is to identify any existing safety concerns within the defined study area in order to evaluate the proposed project impacts at these locations. Historical accident records were obtained from the City of Tukwila for the most recent three -year period available (2001 to 2003). Table 3 provides a summary of the accident records at each study intersection. Both the annual average and the accident rate per Million Entering Vehicles (MEV) are summarized. The accident rate, expressed in terms of accidents per MEV, is an important measure since it factors in the observed traffic volumes in the calculations and provides a perspective in relation to the total entering volume (TEV). The average daily traffic (AM') for the MEV calculation was estimated at each location by multiplying the existing PM peak hour TEV by ten, as PM peak hour traffic volumes typically represent approximately 10- percent of the ADT. Accident data was collected for the four study intersections nearest the site, as they will be impacted most significantly by project trips. The study intersections along Interurban Avenue S to the south of I -5 were analyzed for purposes of determining the arterial LOS only. Average /Year 0.57 0.43 0.78 0.04 As is shown in Table 2, the intersections of Interurban Avenue S /Gateway Drive S and Interurban Avenue S /48th Avenue S both have had 15 reported accidents occur between 2001 and 2003. The remaining intersections have had less than ten accidents reported over R� the last ten years. The four nearest study intersections all show an MEV rate of less than 1.0, 0 which suggests that no unusual safety conditions exist. J� ��1� Interurban Retail, Tukwila, WA Transit Service King County Metro transit provides transit service in the study area and near the project site. Metro Routes 124 and 154 provide service along Interurban Avenue S connecting the immediate area around the site with Allentown, Southcenter, Seattle, Kent, Auburn and other regional destinations. Bus stops are located near the intersections of Interurban Avenue S with 48th Avenue S and Gateway Drive S. Additional Metro routes make scheduled stops at the Interurban Park and Ride lot located to the south of the site near the intersection of Interurban Avenue S/52" Avenue S. Based on existing transit opportunities, the site should be considered reasonably well served and accessible by transit. Non - Motorized Facilities Sidewalks, curb, and gutter are provided along the east side of Interurban Avenue S near the project site, while pedestrian access is restricted on the west side. Sidewalks are also provided along Gateway Drive S, the south side of S 133'' Street, and the east side of 48th Avenue S. Sidewalks exist intermittently elsewhere in the site vicinity. Each of the signalized study area intersections provides pedestrian crosswalks, push buttons, and signal heads to facilitate pedestrian activity. The site is adequately served by the existing non - motorized facilities. The Transpo Group 104209.00`; DRAFT July 2004 Interurban Retail, Tukwila, WA This section documents the potential impacts of the proposed project on the study area roadways and intersections. It includes a summary of the project trip generation, distribution, future traffic volumes, and the potential impacts to traffic volumes, operations, transit, traffic safety, and non - motorized facilities. Trip Generation To determine the extent of the anticipated impact for the proposed project, trip generation was projected for the weekday PM peak hour. The Starbucks trip generation estimate is based on a trip generation study previously conducted specifically for Starbucks stores. This study was conducted by Transportation Engineers Northwest in 2002 at five Puget Sound area Starbucks locations. ITE Trip Generation, 7 Edition, was used to determine the total trip generation for the remaining uses. Trip rates identified for the Specialty Retail (ITE Land Use #810), and Fast -Food Restaurant without Drive -Thru (rl'h Land Use #933) land uses were used. The ITE Trip Generation Handbook does not provide pass -by rates for the Fast Food Restaurant without Drive -Thru land use, so a related use: Fast Food Restaurant with Drive -Thru (ITE Land Use #934) was utilized. No pass -by rate is provided by ITE for Specialty Retail. To provide a conservative analysis, no pass -by rate was assumed for this portion of the site. In addition, no trip credit has been taken for the previous uses of this site. Table 4 shows the PM peak hour trip generation for the proposed project.

Prior to initiating the LOS analysis, the trip distribution was reviewed and approved by City Staff. The net -new project trips, for the PM peak hour, were The Transpo Group 104209.00; 04209r1.doc 12 Interurban Retail, Tukwila, WA DRAFT July 2004 then assigned to the study intersections based on the City approved trip distribution. The project trip distribution is shown in Figure 5, while the project trip assignment for the PM peak hour is shown in Figure 6. The resulting future with - project traffic volumes are summarized in Figure 7. Traffic Volume Impacts The traffic volumes associated with the proposed development were compared to the PM peak hour future with - project traffic forecasts to gauge the traffic volume impacts of the proposed project.

Interurban Retail, Tukwila, WA Site Access Analysis Unsignalized driveway LOS analyses were conducted using Synchro 5.0, which is based on 2000 HCM unsignalized intersection methodologies. Traffic volumes were developed at the site access locations based on turning movement counts conducted in June 2004 at the two shared private driveways that connect with Interurban Avenue S. The total project trips (new plus pass -by), were assigned to the existing driveway volumes generated by the other neighboring uses that share these driveways. The two -way center left -turn lane on Interurban Avenue S provides a refuge by which vehicles making a westbound left turn from either driveway can use in order to complete the turn in two stages depending on the timing of gaps in traffic on Interurban Avenue S. This two -stage gap process is possible without conflict from other turns as the driveways do not have an opposing approach to the west. The two -stage gap use was assumed in the reported driveway LOS analysis. The driveway LOS results are presented in Table 8. The LOS worksheets are included in Appendix B. Table 8.

This analysis focuses on the PM peak hour which generally represents the highest outbound volumes for uses adjacent. Non - Motorized Facilities Pedestrian facilities currently exist in the area and adjacent to the site which will support the connection of the site to available transit service, both existing and future. These facilities include a sidewalk along the east side of Interurban Avenue S, which connects to other sidewalks and leads to designated transit stops in the area. Parking As currently proposed, the project will provide 58 parking stalls in an on -site, paved surface parking lot. City of Tukwila Parking Code requires 58 stalls for this site, which is met by the proposed supply. A parking demand analysis was also completed to determine the adequacy of the parking supply. Using Parking Generation (ITE, 2"d Edition), weekday peak parking generation rates were developed for the site. For the Starbucks portion of the site, the average peak parking rate for ITE land use #836 (Fast Food with Drive -In Window) was used, while ITE land use #837 (Fast Food Without Drive -In Window) was used for the Quiznos portion of the site. The peak parking demand for the balance of the development was determined using ITE land use #820 (Shopping Center), as no parking rates are provided for ITE land use #810 (Specialty Retail). The Shopping Center land use classification is the closest related land -use �E C to Specialty Retail. Table 9 shows the results of the parking demand analysis.

Traffic Safety Impacts Given the minimal level of traffic expected to be generated by the proposed project, combined with the operational impacts summarized previously for the study area intersections, this project is not likely to adversely impact the operational safety of the roadways or intersections within the defined study area. The previous safety analysis included in this report identified no existing safety deficiencies to which the project would impact. Transportation Impact Fees The City of Tukwila has established transportation impact fees in TMC 9.48.140. The current transportation impact fee schedule identifies ten improvement projects throughout the city. Developments that generate trips that impact any one of these projects by five or more trips must pay a fee per trip. Based on the project trip distribution and assignment noted in Figures 5 and 6 and the anticipated local nature of project trips, only one of the projects currently identified in the impact fee schedule is impacted by five or more project trips. The Interurban Bridge widening project will widen the bridge to allow dual left turn lanes. The per trip fee for this improvement project is $240, equating to a total impact fee for this project of approximately $1,440. Interurban Retail, Tukwila, WA DRAFT July 2004 Summary /Conclusions The proposed project would consist of a single 5,700 -sf (approximate) retail building to be located on the east side of Interurban Avenue S between the intersections of Interurban Avenue S /Gateway Drive S and Interurban Avenue S /48th Avenue S. The retail building will include approximately 1,700 sf of space for a Starbucks Coffee shop with drive -thru window, approximately 1,365 sf for a fast food restaurant without drive -thru, and 2,650 sf of specialty retail space. Access to the site is proposed via two existing shared private driveways located on the east and west sides of the site. The site is currently vacant, though it formerly was the site of a gas station and convenience market. No trip credit has been taken, assuring a conservative analysis and estimate of potential project impacts. The proposed project is expected to generate approximately 100 total trips during the PM peak hour, with approximately 40 considered new to the area, and 60 considered pass -by trips. The scope of the analysis was coordinated with City of Tukwila Staff. The following summarizes the key points of the analysis. • Future baseline analyses incorporated general increases in background growth. The results of the analysis indicated that the signalized off -site study intersections adjacent to the site on Interurban Avenue S are expected to operate at LOS C or better during the PM peak hour, while the intersections on the far southern end of the arterial segment would operate at LOS E or F. However, the Interurban Avenue arterial segment is expected to operate at LOS C overall during the PM peak hour. • Based on the future baseline traffic volumes and the project trip assignment, the proposed project is expected to increase traffic volumes by 1 percent or less in the PM peak hour. • The with- project levels of service indicate that the off -site signalized study intersections are expected to operate at the same LOS as in baseline conditions. Delay at the off -site study intersections are anticipated to either remain the same or increase by less than one second per average vehicle. The LOS for the Interurban Avenue S arterial segment is projected to operate at LOS C in the future under with - project conditions, meeting the City's LOS E standard. • Analyses of the site access points indicate that the two shared private access driveways would operate at LOS C in the future under with- project conditions. • Overall traffic volumes are expected to increase by 1- percent or less during the PM peak period as a result of the project, thus not significantly increasing traffic volumes within the area beyond what the future transportation network can accommodate. This minor increase in traffic volumes is not anticipated to affect overall safety within the study area. • The proposed project's parking supply of 58 stalls adequately accommodates the peak parking demand projected for the site. • No transportation mitigation, above the payment of the standard Transportapn Impact Fees previously noted, has been identified for this project.
