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 Country Meadow Estates II is a proposed residential development comprised of 29 single family homes located within the Yelm Urban Growth Area (UGA) of Thurston County. The subject site is bordered to the east by Morris Road SE situated on tax parcel #: 22730410000 comprised of 5.0-acres. Access to and from the site is proposed via one new roadway extending west from Morris Road SE with westerly connection to Country Meadows I and northerly connection to Vancil Court SE. 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.

The closest stop in relation to the subject site is located at the intersection of SR 507 & Bald Hill Road SE (~1,200 feet north). 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 two outlying study intersections and the access along Morris Road SE (school still in session). Each intersection is listed below. • SR 507 & Bald Hill Road SE/Creek Street SE (6/14/2023) • Bald hill Road SE & Marris Road SE (6/14/2023) • Morris Road SE at proposed point of access (6/14/2023) Data were obtained during the PM peak period from 4:00-6:00 PM. The single hour representing peak volumes for the PM time periods are then determined and used for capacity analysis. Figure 3 highlights existing 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 2: 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. $11,482,200 Bald Hill Rd ID #: Yelm 13 14 City Limits to 5 Corners This project is a feasibility study to identify a project that resolves seasonal flooding issues. $70,000 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 each intersection studied for this project during routine PM peak hour field counts. The intersection of SR 507 & Bald HeathTraffic.com Country Meadow Estates II TIA 9 Hill Road SE/Creek Street SE received two pedestrians, one crossing the north leg and one crossing the east leg. The intersection of Bald Hill Road SE & Morris Road SE received one bicyclist crossing the Morris Road SE intersection leg. Non motorist infrastructure in the area is consisted of continuous sidewalk along Bald Hill Road SE which provides connection to SR 507 where many amenities and transit opportunities are present. 3.6 Existing Level of Service 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 signalized intersections, LOS is determined by the overall average delay. For side-street stop-controlled intersections, LOS is determined by the approach with the highest delay. Table 3 below summarizes existing LOS and delays for the key intersections of study.

HeathTraffic.com Country Meadow Estates II TIA 10 State Level of Service Standards3: SR 507 also has an adopted a Level of Service Standard D. SR 507 & Bald Hill Road SE/Creek Street SE: Is shown to operate with acceptable LOS C conditions in the PM peak hour. Bald Hill Road SE & Morris Road SE: Is shown to operate with LOS F conditions for the northbound approach (i.e., drivers from Morris Road waiting to enter Bald Hill Road). This is due to the observed 136 vehicles attempting to make a left-turn (compared to 13 right-turning vehicles) in the peak hour. According to the City’s Transportation System Plan4 Project Y9 intends to reconstruct Bald Hill Road to comprise three-lanes (presently two-lanes) from Yelm Avenue to the Western Chehalis Rail. A three-lane cross-section would accommodate a center two- way left-turn lane across Morris Road SE whereby motorists could perform two- staged entry to the roadway. Additional analysis on the improvement and its affect on operations will be examined in Section 4. Several other projects in the city are also anticipated to reduce overall congestion such as the SR 507/510 Loop extensions. 3 WSDOT – Level of Service Standard - ArcGIS 4 City of Yelm Transportation System Plan - 2022 HeathTraffic.com Country Meadow Estates II TIA 11 4. 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. The magnitude of the anticipated vehicle trip generation for the proposed project was derived from the Institute of Transportation Engineers (ITE) publication, Trip Generation, 11th Edition. Based on the proposed development, the designated land use is defined as LUC – 210 Single-Family Detached Housing. Dwelling units were used as the input variable and ITE’s equations were used to determine trip ends. ITE trip generation sheets have been included in the appendix for reference. See Table 4 below. Table 4: Project Trip Generation Land Use Units AWDT AM Peak-Hour Trips PM Peak-Hour Trips In Out Total In Out Total LUC 210 Single Family 29 323 6 18 24 20 11 31 Based on the data presented in Table 4, the project is estimated to generate 323 average weekday daily trips with 24 trips (6 inbound / 18 outbound) occurring in the AM peak hour and 31 trips (20 inbound / 11 outbound) occurring in the PM peak hour. 4.2 Distribution & Assignment Trip distribution describes the process by which project generated trips are dispersed on the roadway network surrounding the site. Trip distribution for this project utilized the TAZ 726—consistent with County Meadows I. Trip distribution herein assumes completion of Country Meadows I whereupon an east-west connection between Morris Road SE & Vancil Road SE will be provided. Therefore, project traffic heading to/from the west may utilize this connection through Country Meadow Estates I. The PM peak hour trip distribution & assignment is shown in Figure 6. HeathTraffic.com Country Meadow Estates II TIA 12 Country Meadow Estates I All traffic was assigned to/from Vancil Road per the initial traffic study. Adjustments, therefore, occurred to travel assignments to/from the east such as Morris Road, Bald Hill, and half of traffic to SR 507 due to a more direct route through Estates II. This resulted in a redistribution of 8 entering and 5 exiting movements from Estates I. Local Neighborhood Rerouting Also taken into consideration, as part of Country Meadow Estates II development and the east/west connectivity, redistribution of local traffic is anticipated. In review of the existing area and in context to the site layout, Figure 5 below shows the anticipated capture area. The new roadway connection would mainly attract drivers going to/from Bald Hill Road SE and/or Morris Road SE. N Figure 5: Reroute Area Figure 4: New East-West Connection HeathTraffic.com Country Meadow Estates II TIA 13 As shown, approximately 35 single-family residences could utilize the new east/west connection. Applying ITE data suggests a total of 37 PM peak hour trips (23 in / 14 out). Applying the same travel assignments to the anticipated routes (e.g., Bald Hill and Morris—no appreciable change to SR 507 is anticipated), results in 2 entering and 1 exiting rerouted motorists. When Country Meadow Estates II is completed, a new east-west roadway connection would be available for nearby residents. The new roadway would provide a through connection from Vancil Road SE to Morris Road SE. The new roadway connection would mainly attract drivers going to/from Bald Hill Road SE and/or Morris Road SE. Rerouted traffic from both the nearby existing residents and The Country Meadow Estates II project are shown in Figure 7, which are included in forecast analysis. 4.4 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 one percent compound annual growth rate to the existing volumes shown in Figure 3. This growth rate was developed from WSDOT volumes along SR 507 just northwest of Bald Hill Road SE which are shown to be consistent from 2016 (ADT – 19,000) to 2019 (ADT – 19,000) (pre-COVID conditions) (2021 ADT – 18,000). Moreover, also taken into consideration are in-process developments within the city which includes: The Hutch5, Durant Street Plat, Alpine Estates, Tahoma Boulevard Apartments, El Rey Burro, The Summit at Thompson Creek, Samantha Ridge, Habitat for Humanity, Liberty Grove, 407 E Yelm Coffee, and Country Meadow Estates I6. PM peak hour pipeline volumes are shown in Figure 8. Forecast 2026 PM peak hour volumes without the project (background growth plus pipeline) are shown in Figure 9 while Figure 10 illustrates forecast 2026 volumes with the addition of project-generated traffic. 5 Based on site visit (6/14/23), approximately 40/118 homes were constructed and occupied. Therefore, 70% of the trips have been applied as pipeline trips. 6 Trips adjusted to account for east-west connectivity.

Per the City’s Transportation System Plan, improvements along Bald Hill Road are planned by way of converting the two-lane roadway to three-lanes. An evaluation was therefore conducted to examine operational improvements with a center two-way left-turn lane along Bald Hill Road and across Morris Road.

Procedures prescribed by WSDOT Design Manual Exhibit 1310-7a were used to ascertain storage requirements at the proposed access intersection via Morris Road SE. Based on forecast 2026 PM peak hour volumes with project and rerouted traffic – a left turn lane would not be warranted. Refer to the appendix for the left turn warrant nomograph. 4.7 Access & Sight Distance Access to and from the site is proposed via a roadway extending west from Morris Road SE. Moreover, a westerly connection to Country Meadows Estates I, will be provided. See Figure 14 on the following page which displays the combined Country Meadows I and II site plan. In accordance with established AASHTO Standards7 and the 35-mph posted speed limit along Morris Road SE, sight lines would need to meet or exceed 390 feet. Based on preliminary measurements, sight lines to the north are shown to be clear in excess of 390- feet. Sight lines to the south are shown to exceed 500-feet. Refer to the figure to the right which shows the sight distance triangle to the north along Morris Road SE. No deficiencies are identified with the proposed access location. 7 AASHTO Green Book Figure 13: Northern Sight Distance FIGURE 14COMBINED SITE PLANCOUNTRY MEADOW ESTATES IINCOUNTRY MEADOW ESTATES I COUNTRY MEADOW ESTATES II 23 HeathTraffic.com Country Meadow Estates II TIA 24 5. CONCLUSIONS & MITIGATION Country Meadow Estates II proposes for the construction of a residential development comprised of 29 single-family homes located within the Yelm Urban Growth Area (UGA) of Thurston County. The subject site is bordered to the east by Morris Road SE within a single tax parcel comprised of 5.0-acres. Access is proposed via one new roadway extending west from Morris Road SE. As part of site development, a new east-west roadway connection from Vancil Road SE to Morris Road SE through Country Meadow Estates I will be provided. Existing LOS is shown to meet city and state LOS standards except for the intersection of Bald Hill Road SE & Morris Road SE which is shown to operate with LOS F conditions. According to the City of Yelm’s Transportation System Plan 2022, Bald Hill Road SE is planned for improvements via upgrading the two-lane section to three- lanes between the Chehalis Railroad to SR 507 (Yelm Avenue). This improvement would ultimately lower delays at the deficient intersection. Based on ITE data, the 29-unit plat is estimated to generate 323 average weekday daily trips with 24 AM peak hour trips and 31 PM peak hour trips. 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 Figure 3. Several pipeline projects have been included in forecast 2026 analysis. Forecast 2026 PM peak hour level of service was shown to continue meeting City standards with the exception of Bald Hill Road SE & Morris Road SE operating at LOS F. The existing Bald Hill Road near Morris Road appears to have sufficient width to accommodate restriping to comprise three-lanes. Upon a three-lane cross-section, the intersection operations would improve from LOS F to LOS D—meeting City standards. Based on the analysis above, recommended mitigation is as follows: 1.Bald Hill Road SE & Morris Road SE is shown to comprise existing deficiencies in the LOS F range. The City has planned improvements along Bald Hill Road that would improve operations and service levels. However, the timing of the planned improvements is unknown. Should mitigation be required on behalf of County Meadow Estates II, a restriping plan as illustrated in Figure 12 would bring the intersection within City LOS standards. Should the City complete the project prior to Country Meadow Estates II development, the intersection would meet standards and no additional mitigation is identified. HeathTraffic.com Country Meadow Estates II TIA 25 2. 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. Initial fees are estimated as follows: 31 PM Peak Hour Trips x $1,497.00 = $46,407.00. Depending on mitigation outcome, credit may be received for any improvements along Bald Hill Road as the roadway is outlined within the City’s Transportation System Plan.
