Project Proposal. The project would include the development of up to 90 single-family detached homes. The existing site is currently occupied by two (2) single-family detached homes, which will be removed as part of the proposed project. Vehicular access to and from the site is proposed via two (2) full access driveways on Railway Road SE. For this analysis, a 2026 horizon year was used. Trip Generation. The proposed Blue Fern Railway Road project is estimated to generate 888 net new weekday daily trips with 66 trips occurring during the weekday AM peak hour (17 in, 49 out) and 87 trips during the weekday PM peak hour (55 in, 32 out). Future Year LOS. Weekday PM peak hour LOS analysis was conducted at three (3) off-site study intersections. All study intersections are anticipated to operate at LOS A during the weekday PM peak hour in 2026 without or with the proposed Blue Fern Railway Road project. Site Access Analysis. The controlled movements at the two site access driveways on Railway Road SE are expected to operate at LOS A in 2026 with 95th percentile queues anticipated to be less than 25 feet during the PM peak hour. Mitigation Off-Site Improvements Based on the results of the analysis shown in this report, no project-specific off-site transportation mitigation is proposed for concurrency or SEPA purposes. Transportation Impact Fees Transportation impacts fees in the City of Yelm are assessed upon new development based on a cost per PM peak hour trip. The current transportation impact fee is $1,497 per PM peak hour trip. The final impact fee calculation will be based on the impact fee rate and project size in effect at the time of building permit issuance. Traffic Impact Analysis Blue Fern Railway Road TENW February 22, 2023 Page 2 INTRODUCTION This Traffic Impact Analysis (TIA) has been prepared for the proposed Blue Fern Railway Road project located at 16314 and 16330 Railway Road SE in Yelm, WA as shown in Figure 1. Project Description The project would include the development of up to 90 single-family detached homes. The existing site is currently occupied by two (2) single-family detached homes, which will be removed as part of the proposed project. Vehicular access to and from the site is proposed via two (2) full access driveways on Railway Road SE. For this analysis, a 2026 horizon year was used. A preliminary site plan is included in Figure 2. Project Approach To analyze the traffic impacts from the proposed Blue Fern Railway Road project, the following tasks were undertaken: Assessed existing conditions through field reconnaissance and reviewed existing planning documents; Documented existing traffic volumes and intersection LOS during the weekday PM peak hour. Documented future planned roadway improvements in the project vicinity. Developed weekday daily, AM, and PM peak hour trip generation estimates. Assigned weekday PM peak hour project-generated trips. Analyzed weekday PM peak hour LOS for future conditions without and with the project at the following study intersections: 1. Rhoton Road NW / Railway Road SE 2. Middle Road SE / Railway Road SE 3. Canal Road SE / Railway Road SE Assessed operations at the two (2) proposed site access driveways including LOS and queuing. Documented proposed traffic mitigation including off-site improvements and payment of transportation impact fees.

The PM peak hour traffic volumes represent the highest hour of traffic between 4:00 and 6:00 p.m. Figure 3 illustrates the existing 2023 PM peak hour traffic volumes at the study intersections. The 2023 traffic count sheets are included in Appendix A. Traffic Impact Analysis Blue Fern Railway Road TENW February 22, 2023 Page 7 Figure 3 2023 Existing Weekday PM Peak Hour Traffic Volumes Traffic Impact Analysis Blue Fern Railway Road TENW February 22, 2023 Page 8 Intersection Levels of Service Weekday PM peak hour level of service (LOS) analysis was conducted at the following three (3) off- site study intersections: 1. Rhoton Road NW / Railway Road SE 2. Middle Road SE / Railway Road SE 3. Canal Road SE / Railway Road SE LOS generally refers to the degree of congestion on a roadway or intersection. It is a measure of vehicle operating speed, travel time, travel delays, and driving comfort. A letter scale from A to F generally describes intersection LOS. At signalized intersections, LOS A represents free-flow conditions (motorists experience little or no delays), and LOS F represents forced-flow conditions where motorists experience an average delay in excess of 80 seconds per vehicle. The LOS reported for signalized intersections represents the average control delay (sec/veh) and can be reported for the overall intersection, for each approach, and for each lane group (additional v/c ratio criteria apply to lane group LOS only). The LOS reported at stop-controlled intersections is based on the average control delay and can be reported for each controlled minor approach, controlled minor lane group, and controlled major- street movement (and for the overall intersection at all-way stop controlled intersections. Additional v/c ratio criteria apply to lane group or movement LOS only). Table 2 outlines the HCM 6th Edition LOS criteria for signalized and stop-controlled intersections based on these methodologies. Table 2 LOS Criteria for Signalized and Stop-Controlled Intersections1 SIGNALIZED INTERSECTIONS UNSIGNALIZED INTERSECTIONS LOS by Volume-to Capacity (V/C) Ratio2 LOS by Volume-to Capacity (V/C) Ratio Control Delay (sec/veh) 1.0 > 1.0 Control Delay (sec/veh) 1.0 > 1.0 10 A F 10 A F > 10 to 20 B F > 10 to 15 B F > 20 to 35 C F > 15 to 25 C F > 35 to 55 D F > 25 to 35 D F > 55 to 80 E F > 35 to 50 E F > 80 F F > 50 F F 1 Source: Highway Capacity Manual (6th Edition), Transportation Research Board, 2016. 2 For approach-based and intersection-wide assessments at signals, LOS is defined solely by control delay. Intersection LOS was calculated using the methodology and procedures outlined in the Highway Capacity Manual (HCM 6th Edition), Transportation Research Board (TRB), using the Synchro 11 software program. The 2023 existing PM peak hour LOS analysis results for the study intersections are summarized in Table 3. The 2023 Existing LOS worksheets are included in Appendix B. It should be noted that the LOS reported at the stop-controlled study intersections was based on the average delay of all legs per Yelm Municipal Code section 18.16.030.

Traffic Impact Analysis Blue Fern Railway Road TENW February 22, 2023 Page 10 FUTURE CONDITIONS AND PROJECT IMPACT ANALYSIS Planned Transportation Improvements Future planned roadway capacity improvements in the project vicinity include the SR 510 Yelm Loop Phase 2 project. The project involves the completion of the Yelm Loop bypass, a two-phased limited access highway intended to provide an alternate route for regional traffic around Yelm’s congested downtown core. Phase 1 of the bypass was constructed in 2010. Phase 2 would complete the Yelm Loop bypass, from its existing terminus at Cullens Road to the intersection of 170th Street and SR 507. Phase 2 improvements include construction of approximately 3 miles of new highway with one travel lane in each direction; a shared-use bicycle and pedestrian pathway; and sidewalks and bike lanes in the more urbanized portion of the corridor. The anticipated project is anticipated to be completed in Fall 2026. Below is a graphic illustrating the Phase 2 Improvements. Project Trip Generation The new weekday daily, AM, and PM peak hour trip generation estimates were based on methodology documented in the Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition for Land Use Code (LUC) 210 (Single-Family Detached Housing). Table 5 summarizes the trip generation estimate for the proposed Blue Fern Railway Road project. Traffic Impact Analysis Blue Fern Railway Road TENW February 22, 2023 Page 11 Table 5 Blue Fern Railway Road – Trip Generation Summary Net New Trips Generated Time Period In Out Total Weekday Daily 444 444 888 Weekday AM Peak Hour 17 49 66 Weekday PM Peak Hour 55 32 87 As shown in Table 5, the currently proposed 90-lot Blue Fern Railway Road project is estimated to generate 888 net new weekday daily trips with 66 net new trips occurring during the weekday AM peak hour (17 in, 49 out) and 87 net new trips during the weekday PM peak hour (55 in, 32 out). Detailed trip generation calculations are included in Appendix C. It should be noted that the reported trip generation estimates include trip credit for the two single family homes currently on the site that will be removed. Project Trip Distribution and Assignment The distribution of project-generated traffic to the adjacent road network was based on a model distribution provided by the Thurston Reginal Planning Council (TRPC). A copy of the TRPC model distribution output is included in Appendix D. It should be noted that the traffic modeling assumes the completion of the SR 510 Yelm Loop Phase 2 project. The TRPC modeling was used to assign the net new weekday PM peak hour trips (55 inbound and 32 outbound) trips generated by the proposed project to the adjacent street network. The resulting assignment of the net new weekday PM peak hour project trips through the study intersections and site access driveways is shown in Figure 4. The new weekday PM peak hour project-generated trips were generally distributed to the vicinity street system as follows: 40 percent to/from the north on SR 510 Extension (via Wilkensen Road SE) 30 percent to/from the west on 1st Street 20 percent to/from the south on Canal Rd SE 10 percent to/from the south on Middle Rd SE Future Traffic Volumes To estimate the future 2026 Baseline PM peak hour traffic volumes, a 2.0 percent annual growth rate was applied to the 2023 existing traffic volumes. The resulting future 2026 Baseline PM peak hour traffic volumes at the study intersections are shown in Figure 5. The 2026 With Project traffic volumes were determined by adding the trip assignment from the proposed development (shown in Figure 4) to the future 2026 Baseline traffic volumes (shown in Figure 5). The 2026 With Project traffic volumes are shown in Figure 6.

The LOS results at the study intersections without and with the proposed project are summarized in Table 6. The detailed LOS worksheets are included in Appendix B. It should be noted that the LOS reported at the stop-controlled study intersections was based on the average delay of all legs per Yelm Municipal Code section 18.16.030.

LOS = Level of Service 2. Delay refers to average control delay of all legs at the intersection per Yelm Municipal Code section 18.16.030, expressed in seconds per vehicle. As shown in Table 6, all study intersections are anticipated to operate at LOS A during the weekday PM peak hour in 2026 without or with the proposed Blue Fern Railway Road project. Site Access Assessment Vehicle access to the site will be provided by two full access driveways on Railway Road SE. To assess operations of the proposed site access locations, level of service (LOS) and queuing were analyzed. The LOS and queue calculations were conducted using Synchro 11 software based on methodology outlined in the Highway Capacity Manual (6th Edition). The reported queues are estimated 95th percentile queues that are exceeded only 5 percent of the time. Table 7 summarizes the results of the 2026 with project LOS and queue analyses. The LOS and queue calculation sheets are included in Appendix B. Traffic Impact Analysis Blue Fern Railway Road TENW February 22, 2023 Page 16 Table 7 Site Access Peak Hour LOS & Queue Summary PM Peak Hour Site Access LOS Delay (sec) 95th % Queue A. Railway Road SE / East Driveway Eastbound Left-Turn A 7.3 0’ Southbound Shared Left-Right A 9.0 < 25’ B. Railway Road SE / West Driveway Eastbound Left-Turn A 7.3 0’ Southbound Shared Left-Right A 8.8 0’ 1. Results based on HCM Methodologies (6th Edition). As shown in Table 7, all turn movements entering and exiting the proposed site access driveways are expected to operate at LOS A during the weekday PM peak hour in 2026. Vehicle queues are all estimated to be statistically 1 vehicle or less. MITIGATION Off-Site Improvements Based on the results of the analysis, the existing transportation facilities are anticipated to accommodate the additional traffic generated by the proposed project. No project-specific off-site transportation improvements are proposed. Transportation Impact Fees Transportation impacts fees in the City of Yelm are assessed upon new development based on a cost per PM peak hour trip. The current transportation impact fee is $1,497 per PM peak hour trip. The final impact fee calculation will be based on the impact fee rate and project size in effect at the time of building permit issuance.
