INTRODUCTION The main goals of this study focus on the assessment of existing roadway conditions and forecasts of newly generated project traffic. The first task includes the review of general roadway information on the adjacent street system and baseline vehicular volumes. Forecasts of future traffic and dispersion patterns on the street system are then determined using established trip generation and distribution techniques. As a final step, appropriate conclusions and mitigation measures are defined if needed. 2. PROJECT DESCRIPTION 407 E Yelm Coffee proposes for the construction of a 450-square foot coffee stand (Building 1) comprised of two drive-through lanes and a 2,400 square foot spec building (Building 2) located within the city of Yelm/Thurston County. The subject site is bordered to the northeast by SR 507 (E Yelm Avenue) situated on 1.32-acres within tax parcel #: 22719342700. Access to and from the site is proposed via one new access extending southwest from SR 507 (E Yelm Avenue). A vicinity map is provided below which highlights the nearby roadway network with the subject site highlighted in red. Figure 2 on the following page displays the conceptual site plan. Figure 1: Vicinity Map N Subject Site FIGURE 2 SITE PLAN 407 E YELM COFFEE N 5 HeathTraffic.com 407 E Yelm Coffee TIA 6 3. EXISTING CONDITIONS 3.1 Existing Street System The primary roadway serving the project is SR 507/E Yelm Avenue, a description is provided below. E Yelm Avenue (SR 507): is a two- to three-lane designated state highway bordering the subject site to the northeast. SR 507 provides connection to Spanaway to the north and to Centralia to the south. Bicycle lanes approximately 4- to 5-feet in width are provided in the vicinity of the project with curb, gutter and sidewalk along either side of the roadway. The posted speed limit in the site vicinity is 25-mph and transitions to 35-mph outside of the city area. 3.2 Transit Service A review of the Intercity Transit regional bus schedule indicates that transit is available within walking distance (under one mile) from the subject site. The closest stop in relation to the subject site is located at the E Yelm Avenue & Clark Road SE intersection (~300 feet southeast of site). The bus route served at the intersection is Route 94 – Boulevard Road/Yelm. Route 94 provides service from the Olympia Transit Center to the Yelm Walmart. Weekday service is provided from 6:04 AM – 9:58 PM with approximately 60-minute headways during peak travel times. Weekend service is provided from 6:39 AM – 9:58 PM with approximately 60-minute headways. Refer to the Intercity Transit website for more detailed information. 3.3 Existing Peak Hour Volumes and Travel Patterns Field data for this study was collected in June 2023 at the proposed point of access along E Yelm Avenue. Data were obtained during the morning and evening peak periods from 7:00-9:00 AM and 4:00-6:00 PM. As coffee shops experience the highest number of trips during in the morning, AM analysis has been included. The single hour representing peak volumes for the AM and PM time periods are then determined and used for capacity analysis. Figures 3 and 4 highlight existing AM and PM peak hour volumes. Count sheets have been included in the appendix for reference.

The city of Yelm’s TIP and the WSDOT STIP both indicated planned improvements in the vicinity of the proposed project, each project is listed and described below. Table 1: Transportation Improvement Projects Name Location Improvement Cost City of Yelm 2nd Ave SE ID #: WA12343 Mosman Ave to 575’ south Construct 5-foot-wide multi-use concrete sidewalk along the west side of 2nd Street SE from Cochrane Park to the existing sidewalk at Mosman Ave. $250,000 Mosman Ave SE ID #: WA-12344 2nd St SE to 3rd St SE Construct sidewalks on both sides of Mosman Ave, install intersection treatment at 2nd St and Mosman Ave. Construct bike lanes from 2nd St to 3rd St. $310,000 Yelm Ave Improvements ID #: WA-12346 1st St to 4th St Construction and repair of sidewalks, installation of new parallel parking, intersection treatment, and access control along both sides of Yelm Ave. $2,321,800 Mosman Ave II ID #: Yelm 13 01 Longmire to Railroad Construct a new road connecting Longmire St with the new Mosman Ave intersection. Bike lanes, sidewalk, street lighting, and storm water improvements are included. Improvements include construction of new road from Longmire to Solberg, and reconstruction of Mosman between Solberg and Railroad. $11482,200 Statewide Transportation Improvement Plan SR 510/Yelm Loop SR 510 Traffic throughout the city is extremely congested at this time. This project will construct the second stage of a new alignment for SR 510 through the city of Yelm. When complete, this project will relieve congestion and improve motorist safety. $58,697,552 Several planned improvements would further increase non-motorist mobility in the area. Moreover, the anticipated new SR 510 loop would relieve congestion along SR 507 (E Yelm Avenue). 3.5 Non-Motorist Activity and Infrastructure Pedestrian and bicycle activity were monitored at the access intersection studied for this project during routine AM and PM peak hour field counts. During the AM peak hour count, five pedestrians were observed traversing the southern side of E Yelm Avenue (SR 507). During the PM peak hour, no pedestrians or bicyclists were observed.

FORECAST TRAFFIC DEMAND & ANALYSIS 4.1 Project Trip Generation Trip generation is defined as the number of vehicle movements that enter or exit the respective project site during a designated time period, such as a specific peak hour (AM or PM) or an entire day. Trip generation for each proposed building is described below. Building 1: Coffee Shop Trip generation for the coffee shop has utilized ITE’s Trip generation Manual, 11th Edition. Land Use Code (LUC) 938 Coffee/Donut Shop with Drive-Through and No Indoor Seating was selected. Drive-through lanes were used as the input variable with ITE average rates to determine trip ends. Building 1 will remain the same in both trip generation scenarios. Trip Generation Adjustments Pass-By Pass-by trips have been considered for this project, pass-by trips, or motorists already passing by the site who decide to make an intermediate stop before proceeding to their primary destination such as coffee shops/commercial/retail services. These trips are not considered as new trips but will impact the site’s access points. ITE reports an AM pass-by rate of 90% and a PM peak hour pass-by rate of 98%. An average of both the AM and PM peak hour pass-by rates has been calculated (94%) and assigned to the average weekday daily trips (AWDT). See Table 2 below. Table 2: Project Trip Generation (Building 1) Land Use DT Lanes Trip Type AWDT AM Peak-Hour Trips PM Peak-Hour Trips In Out Total In Out Total LUC 938 Coffee Shop 2 Primary 21 4 4 8 0 1 1 Pass-By 337 36 36 72 15 14 29 Total Trips 358 40 40 80 15 15 30 Building 1 is anticipated to generate 358 total average weekday daily trips with 80 total AM peak hour trips and 30 total PM peak hour trips. Approximately 90% of all generated trips are to be in the form of pass-by. HeathTraffic.com 407 E Yelm Coffee TIA 11 Building 2: As building 2 is a 2,400 square foot spec building, two different scenarios are proposed per the owner’s direction on anticipated usage. 1. Office Building (Scenario 1) 2. Axe Throwing Facility (Scenario 2) Scenario 1: Trip generation for scenario 1 has also utilized ITE’s Trip generation Manual, 11th Edition. Land Use Code (LUC) 712 Small Office Building was selected with square footage used as the input variable and ITE average rates to determine trip ends. Scenario 2: Scenario 2 assumes the building will comprise an axe throwing facility. As there is no Land Use Code (LUC) available for an axe throwing facility, a custom trip generation has been prepared below. It is important to note that the facility will only be opened Thursdays (5-8 PM), Fridays (5-9 PM), Saturdays (10 AM-9 PM) & Sundays (12-7 PM). The facility will not be open during the AM peak hour. The Axe Throwing facility is anticipated to incorporate 8 “throwing lanes”. Each lane could accommodate a maximum party of 4 people. As not all parties are comprised of 4 people, assumptions are as follows: 2.5 average person occupancy (per lane) and 2 person per vehicle. 8 Throwing Lanes X 2.5 Average Person Occupancy = 20 People/2 people per vehicle = 10 trips It is also assumed that there would be overlap between departing guests and arriving guests which would result in 20 PM peak hour trips (10 inbound / 10 outbound).

Pass-by trips are estimated with 337 average weekday daily trips with 72 AM pass-by trips and 29 PM pass-by trips. 4.2 Distribution & Assignment Trip distribution describes the process by which project generated trips are dispersed on the roadway network surrounding the site. The 407 E Yelm Coffee project includes both primary and pass-by trips. Primary & pass-by trip distribution is provided on the following page. HeathTraffic.com 407 E Yelm Coffee TIA 13 Primary Trips: Trip distribution percentages are based on TAZ map 721 provided by TRPC, which shows a (65%/35% southeast/northwest) split at the point of access along E Yelm Avenue. Pass-By Trips: Pass-by trips are vehicles already on the street system who decide to make an intermediate stop before proceeding to their primary destination. AM pass-by trip percentages are anticipated with a (55%/45%) (southeast/northwest) split and PM pass-by percentages are anticipated with a (50%/50%) (southwest/northwest) split, which are based on the existing AM and PM travel patterns. Figures 5 & 6 highlight AM and PM peak hour trip distribution & assignment for scenario 1; scenario 2 is shown in Figures 7 & 8. 4.3 Future Peak Hour Volumes A 3-year horizon of 2026 was used for future traffic delay analysis. Forecast 2026 background traffic volumes were derived by applying a conservative one percent compound annual growth rate to the existing volumes shown in Figures 3 and 4. This growth rate was developed from WSDOT volumes along SR 507 just south of 1st Street which are shown to decrease from 2016 (ADT – 18,000) to 2021 (ADT – 17,000). Moreover, also taken into consideration are in-process developments within the city which includes: The Hutch, Durant Street Plat, Alpine Estates, Tahoma Boulevard Apartments, El Rey Burro, The Summit at Thompson Creek, Samantha Ridge, Habitat for Humanity, and Liberty Grove. As no AM peak hour pipeline volumes are available, the PM peak hour volumes have been used with a 20% reduction and flipped directionalities. AM and PM peak hour pipeline volumes are shown in Figures 9 and 10. Forecast 2026 AM peak hour volumes without and with the project for scenario 1 is provided in Figure 11. Figure 12 displays PM peak hour volumes without and with the project for scenario 1. Scenario 2 forecast volumes are shown in Figures 13 and 14. 407 E YELM COFFEE N 507 E Y E L M A V ECLARK RD SENE 4TH STSITE ST O P -2 0 2 0 1 6 2 0 1 6 -1 6 AM PEAK HOUR PRIMARY TRIPS INBOUND: 7 VPH OUTBOUND: 5 VPH ST O P 0 5 3 2 2 0 PRIMARY TRIPS PASS-BY TRIPS AM PEAK HOUR PASS-BY TRIPS INBOUND: 36 VPH OUTBOUND: 36 VPH 35% 65% PASS-BY 55% 45% PASS-BY 55% 45% FIGURE 5 AM PEAK HOUR TRIP DISTRIBUTION & ASSIGNMENT SCENARIO 1 14 407 E YELM COFFEE N 507 E Y E L M A V ECLARK RD SENE 4TH STSITE ST O P -7 7 7 7 8 -8 PM PEAK HOUR PRIMARY TRIPS INBOUND: 2 VPH OUTBOUND: 4 VPH ST O P 0 1 3 1 1 0 PRIMARY TRIPS PASS-BY TRIPS PM PEAK HOUR PASS-BY TRIPS INBOUND: 15 VPH OUTBOUND: 14 VPH 35% 65% PASS-BY 50% 50% PASS-BY 50% 50% FIGURE 6 PM PEAK HOUR TRIP DISTRIBUTION & ASSIGNMENT SCENARIO 1 15 407 E YELM COFFEE N 507 E Y E L M A V ECLARK RD SENE 4TH STSITE ST O P -2 0 2 0 1 6 2 0 1 6 -1 6 AM PEAK HOUR PRIMARY TRIPS INBOUND: 4 VPH OUTBOUND: 4 VPH ST O P 0 3 3 1 1 0 PRIMARY TRIPS PASS-BY TRIPS AM PEAK HOUR PASS-BY TRIPS INBOUND: 36 VPH OUTBOUND: 36 VPH 35% 65% PASS-BY 55% 45% PASS-BY 55% 45% FIGURE 7 AM PEAK HOUR TRIP DISTRIBUTION & ASSIGNMENT SCENARIO 2 16 407 E YELM COFFEE N 507 E Y E L M A V ECLARK RD SENE 4TH STSITE ST O P -7 7 7 7 8 -8 PM PEAK HOUR PRIMARY TRIPS INBOUND: 10 VPH OUTBOUND: 11 VPH ST O P 0 7 7 4 3 0 PRIMARY TRIPS PASS-BY TRIPS PM PEAK HOUR PASS-BY TRIPS INBOUND: 15 VPH OUTBOUND: 14 VPH 35% 65% PASS-BY 50% 50% PASS-BY 50% 50% FIGURE 8 PM PEAK HOUR TRIP DISTRIBUTION & ASSIGNMENT SCENARIO 2 17 FIGURE 9 AM PEAK HOUR PIPELINE VOLUMES 407 E YELM COFFEE N 507 E Y E L M A V ECLARK RD SENE 4TH STSITE ST O P 5 4 0 0 0 0 8 5 18 FIGURE 10 PM PEAK HOUR PIPELINE VOLUMES 407 E YELM COFFEE N 507 E Y E L M A V ECLARK RD SENE 4TH STSITE ST O P 1 0 6 0 0 0 0 6 7 19 FIGURE 11 FORECAST 2026 AM PEAK HOUR WITHOUT & WITH PROJECT 407 E YELM COFFEE N 507 E Y E L M A V ECLARK RD SENE 4TH STSITE SCENARIO 1 ST O P 7 5 7 2 5 1 9 2 2 1 8 5 7 2 ST O P 7 7 7 0 0 0 0 5 8 8 WITHOUT PROJECT WITH PROJECT 20 FIGURE 12 FORECAST 2026 PM PEAK HOUR WITHOUT & WITH PROJECT 407 E YELM COFFEE N 507 E Y E L M A V ECLARK RD SENE 4TH STSITE SCENARIO 1 ST O P 9 4 7 8 1 0 8 9 8 9 4 ST O P 9 5 4 0 0 0 0 9 0 2 WITHOUT PROJECT WITH PROJECT 21 FIGURE 13 FORECAST 2026 AM PEAK HOUR WITHOUT & WITH PROJECT 407 E YELM COFFEE N 507 E Y E L M A V ECLARK RD SENE 4TH STSITE SCENARIO 2 ST O P 7 5 7 2 3 1 9 2 1 1 7 5 7 2 ST O P 7 7 7 0 0 0 0 5 8 8 WITHOUT PROJECT WITH PROJECT 22 FIGURE 14 FORECAST 2026 PM PEAK HOUR WITHOUT & WITH PROJECT 407 E YELM COFFEE N 507 E Y E L M A V ECLARK RD SENE 4TH STSITE SCENARIO 2 ST O P 9 4 7 1 4 1 4 1 1 1 1 8 9 4 ST O P 9 5 4 0 0 0 0 9 0 2 WITHOUT PROJECT WITH PROJECT 23 HeathTraffic.com 407 E Yelm Coffee TIA 24 4.4 Future Level of Service Forecast 2026 peak hour delays were determined through the use of the Highway Capacity Manual 7th Edition. Capacity analysis is used to determine level of service (LOS) which is an established measure of congestion for transportation facilities. The range1 for intersection level of service is LOS A to LOS F with the former indicating the best operating conditions with low control delays and the latter indicating the worst conditions with heavy control delays. Detailed descriptions of intersection LOS are given in the Highway Capacity Manual. Level of service calculations were made through the use of the Synchro 12 analysis program. For side-street stop-controlled intersections, LOS is determined by the approach with the highest delay. Table 6 below summarizes forecast 2026 AM and PM peak hour calculated delays for both scenarios at the access intersection with project generated traffic.

As such, no operational deficiencies are identified as a result of the proposed development. 4.5 Access & Sight Distance Access to and from the site is proposed via one new access point extending southwest from SR 507 (E Yelm Avenue). In accordance with established AASHTO Standards4 and the 25-mph posted speed limit along SR 507 (E Yelm Avenue), sight lines would need to meet or exceed 280 feet. Given that the facility is a WSDOT State Route, WSDOT sight distance standards were also reviewed. Based on the 25-mph posted speed limit, WSDOT would require sight lines to meet or exceed 155 feet (driveway to receive less than 1,500 vehicles daily). Based on preliminary measurements, sight lines are shown to exceed 300 feet in either direction. No deficiencies are identified with the proposed access location. As part of site development, a sidewalk will be constructed on-site to allow non- motorist access to and from the site. 4 AASHTO Green Book (pg. 4.13) HeathTraffic.com 407 E Yelm Coffee TIA 26 5. CONCLUSIONS & MITIGATION 407 E Yelm Coffee proposes for the construction of a coffee stand comprised of two drive-through lanes and a 2,400 square foot spec commercial building located within the city of Yelm. The subject site is bordered to the northeast by SR 507 (E Yelm Avenue), situated on 1.32-acres within a single tax parcel. Access to and from the site is proposed via one new access extending southwest from SR 507 (E Yelm Avenue). AM and PM peak hour counts were conducted along SR 507 (E Yelm Avenue) at the proposed point of access to establish baseline traffic conditions. The 2,400 square foot building is planned as either general office space or an axe throwing facility. Trip data were derived through the ITE Trip Generation Manual for the coffee and office uses. However, the axe throwing use, not available in the manual, used site-specific operations to generate trip activity. In total, Scenario 1 Coffee and Office is estimated to produce 84 AM and 35 PM peak hour trips. Scenario 2 Coffee and Axe Throwing is estimated to produce 80 AM and 50 PM peak hour trips. Most trips associated with the site are considered pass-by and not new to the city’s system. A three-year horizon of 2026 was used to assess future conditions with and without project generated traffic. Forecast 2026 peak hour analysis included a 1.0% background growth rate to the existing volumes shown in Figures 3 and 4. Moreover, AM and PM peak hour pipeline volumes from several nearby projects have been included in forecast 2026 analysis. Forecast 2026 AM and PM peak hour level of service was shown to operate with LOS C conditions with the project for both project scenarios, meeting city and state LOS standards. No operational deficiencies are identified with either project scenario. Based on the analysis above, recommended mitigation is as follows: 1. The subject development would be subject for Transportation Facilities Charge per city of Yelm requirements. The city imposes a fee of $1,497.00 per PM peak hour primary trip. Fees would be assessed by the City based on final uses and prior to building permit issuance. No other mitigation is identified. Please feel free to contact me should you have any questions.
