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 information on the roadways serving the site, public transportation information, and baseline level of service. 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 Cape George BLA is a proposed single-family project consisting of 70 dwelling units in unincorporated Jefferson County. The subject site comprises several parcels for a collective area of approximately 22-acres. See below aerial image illustrating the project boundaries. A conceptual site plan is presented in Figure 2 which identifies project access and layout configuration. For reference herein, the “north portion” is considered the area on the north side of Cape George Road encompassing 42 lots; the “central portion” is the area on the south side of Cape George Road with 9 lots; and the “south portion” is the southernmost area north of Nelson’s Landing Road with the remaining 19 lots.

EXISTING CONDITIONS 3.1 Existing Street System The primary roadways serving the subject site are listed and described below. Cape George Road: is a two-lane minor collector roadway bisecting the subject site. Travel lanes are approximately 10- to 11-feet wide. Shoulders are composed of narrow paved segments or grass/gravel. West with its intersection to S Discovery Road, the roadway has a posted speed limit of 35 mph. Approximately 1,200 feet west of S Discovery Road, the speed limit increases to 50 mph. This speed limit transition occurs along the subject site frontage between tax parcel #’s 96360-0701 and -0801. S Discovery Road: is a north-south, two-lane minor collector roadway located east and south of the subject site. Travel lanes are approximately 11-feet wide. Shoulders are composed of paved segments 3- to 7-feet wide. The roadway has a posted speed limit of 35-40 mph near the subject site. 3.2 Existing Peak Hour Volumes and Travel Patterns Field data for this study was obtained and collected in September of 2020. Traffic counts were performed at the primary intersections receiving the bulk of anticipated vehicular impacts. Field data was collected from 4:00 PM - 6:00 PM, which generally reflects the highest levels of congestion with respect to traffic and delays during a 24-hour period. The busiest one-hour is then derived from the each intersection count, known as the peak hour, to depict worst case conditions. Figure 3 on the following page illustrates the intersections of study and their associated weekday PM peak hour volumes. Intersections field counted are summarized below. • Cape George Rd/Florence St & S Discovery Rd • S Jacob Miller Rd & S Discovery Rd • S Jacob Miller Rd & Hwy 20 • Discovery Rd (Mill Rd) & S Discovery Rd • Hwy 20/W Sims Way & Discovery Rd/Mill Rd 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 5 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 6 3.3 Transit Service A review of the Jefferson Transit regional route maps indicates the nearest transit routes in the area are served via Route 1 – Brinnon / Quilcene / Tri Area Route, Route 6A/6B – Tri Area Loop, Route 7 – Poulsbo / Port Ludlow / Tri Area Route and Route 8 – Sequim Route. The nearest stop providing service to these routes is located at the intersection of S Jacob Miller Road & Highway 20 (~0.51 miles northeast). Service is provided weekdays from approximately 5:45 AM - 6:57 PM and Saturdays from approximately 6:35 AM - 7:55 PM with stops at major intersections along the routes. Additionally, these routes provide connection to Haines Park and Ride. Haines Park and Ride, located ~2.25 miles northeast of the subject site, provides service to Kingston, Olympia, Port Angeles, SeaTac, Seattle and the Coho Ferry. Moreover, the Port Townsend Ferry Terminal is located approximately 3.23 miles northeast of the proposed development. Service is provided from this terminal to Coupeville daily from 6:30 AM – 9:10 PM. Given the nature of the incoming project and proximity, transit use is anticipated. Refer to the Jefferson Transit schedule and WSDOT Winter 2021 Sailing Schedule for more detailed information. 3.4 Non-Motorist Traffic During field observations, little non-motorist transport was observed at the study intersections. The area is generally rural in nature with limited walkable nearby amenities aside from the Larry Scott Trail. Sidewalks and/or bike lanes, become available to the north near city of Port Townsend limits. The Larry Scott Trail bisects the subject site and travels from the Port Townsend waterfront to the Milo Curry Trailhead. The trail is approximately 7.3 miles long and provides multi-use non-motorist recreational opportunities. 3.5 Project Accesses Access to and from the site is proposed via five new connections to the local street system. Three accesses are proposed on Cape George BLA serving the north and central portions. A single access by way of Nelson’s Landing and a single access by way of Discovery Road is proposed to serve the south portion. Currently, two driveways extending north from Cape George Road provide access to single-family residences and would remain in present locations. The westerly driveway is proposed to be improved as a private roadway and serve as the primary access for the northerly portion of the subject project. The easterly driveway, approximately 200 feet to the east, would remain and continue serving as access for only the single-family residence via an access easement. 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 7 See Figure 2 for site plan design and proposed locations. All new accesses shall be designed so as to allow sufficient sight lines in accordance with Jefferson County and American Association of State Highway and Transportation Officials (AASHTO) standards. A final survey for sight line requirements/verification may be required upon final site design. 3.6 Level of Service Peak hour delays were determined through the use of the Highway Capacity Manual 6th 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 2016 Highway Capacity Manual. Level of service calculations were made through the use of the Synchro 10 analysis program. Table 1 summarizes existing LOS and delays for the key intersections of study.

Moreover, Highway 20 is considered as a Highway of Statewide Significance through WSDOT and has a LOS D standard at the associated intersections of study. As shown in Table 1, existing conditions operate satisfactorily at LOS C or better for all directional movements during the critical PM peak travel hour. No operational deficiencies are identified for the study intersections. 3.7 Roadway Improvements A review of the current Jefferson County Six-Year 2021-2026 Transportation Improvement Program, the Port Townsend Capitol Projects Directory and the WSDOT STIP (2021-2023) indicates that projects are currently planned in the vicinity of the site. Descriptions of the nearest improvement projects are summarized below. Roundabouts - Kearney Street and Mill Road at Highway 20: The scope of these projects intend to construct compact roundabouts on SR 20 at its intersections with Mill Road/Discovery Road and Kearney Street. The existing signal systems are outdated and have reached the end of their useful life. The roundabouts were shown to improve level of service and are expected to increase safety. SR 20 & Mill/Discovery Road is a study intersection in this evaluation; shown below is a conceptual intersection schematic. The project has an estimated cost of $970,000 with a construction date in Spring 2023. Discovery Road Bikeway & Sidewalks Project from Rainier Street to McClellan Street – STPUS-7627(001): The scope of this project intends to construct a bikeway and sidewalk on Discovery Road. The project has an estimated cost of $2,500,000 and is expected to begin in October 2021. 2 Jefferson County Comprehensive Plan, Transportation Element. 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 9 4. FORECAST TRAFFIC DEMAND AND 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 the PM peak hour 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, 10th Edition. The designated land use is defined as Single-Family Detached Housing (LUC 210). Dwelling units was used as the input variable and equations were used to determine trip ends. Table 2 summarizes anticipated vehicular movements for the average weekday daily trips (AWDT), AM peak hour and PM peak hour. Table 2: Project Trip Generation Land Use Dwelling Units AWDT AM Peak-Hour Trips PM Peak-Hour Trips In Out Total In Out Total Single-Family 70 749 13 41 54 45 27 72 The project is estimated to generate 749 new average weekday daily trips with 54 trips occurring the AM peak hour and 72 trips in the PM peak hour. 4.2 Distribution & Assignment Trip distribution describes the anticipated travel routes for inbound and outbound project traffic during the peak hour study period. Trip distribution percentages are based on the location of nearby major arterials and amenities. PM peak hour trips are primarily comprised of commuter-based (returning home) and recreational-based trips. Anticipated distribution percentages and travel routes for the outlying study intersections (Figure 4A) and access intersections (Figure 4B) are illustrated on the following pages. 4.3 Future Peak Hour Volumes A 5-year horizon of 2026 was used for future traffic delay analysis to depict conditions with full project buildout based upon current zoning. Forecast 2026 background PM peak hour volumes were derived by applying a 1.0 percent compound annual growth rate per year to the existing traffic volumes, which has been used for nearby analysis in the past. Forecast 2026 PM peak hour volumes without project are shown in Figure 5. Figures 6A and 6B illustrate forecast 2026 volumes with the addition of project-generated traffic at the outlying study intersections and access intersections. 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 10 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 11 HEATH & ASSOCIATESTRAFFIC AND CIVIL ENGINEERINGPM PEAK HOUR TRIP DISTRIBUTION & ASSIGNMENTNACCESS INTERSECTIONSPM PEAK HOUR TRIP DISTRIBUTION & ASSIGNMENTFIGURE 4B50%10%A& WESTERN ACCESSCAPE GEORGE RDB& EASTERN ACCESS00142236300020CAPE GEORGE RDC& ACCESSNELSON'S LANDING RDD& S DISCOVERY RDACCESS12300000011101115NEW PM PEAK HOUR TRIPSINBOUND: 45 VPHOUTBOUND: 27 VPH27%27%13%11ABCDCAPE GEORGE BLA2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 12 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 13 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 14 HEATH & ASSOCIATESTRAFFIC AND CIVIL ENGINEERINGFORECAST 2026 PM PEAK HOUR VOLUMES WITH PROJECTNACCESS INTERSECTIONSFIGURE 6BA& WESTERN ACCESSCAPE GEORGE RDB& EASTERN ACCESS00142211363000780CAPE GEORGE RDC& ACCESSNELSON'S LANDING RDD& S DISCOVERY RDACCESS1231107600551111005911511ABCDCAPE GEORGE BLA2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 15 4.4 Future Level of Service Level of service analyses were made of the future 2026 PM peak hour volumes without and with project related trips added to the key roadways and intersections. This analysis once again involved the use the Synchro 10 analysis program. Delays for the key intersection movements under future conditions are shown in Table 3 below.

It should be noted that the intersection of Hwy 20 & Discovery Road is planned for a future roundabout due to the outdated traffic signal equipment. WSDOT’s Intersection Control Evaluation indicates the intersection is anticipated to operate with LOS A conditions once constructed. The roundabout was not assumed in the analysis due to uncertain funding/construction timing. The roundabout may also improve conditions at S Discovery Road (Mill Road) & Discovery Road as less delay and queues are expected at the nearby signal. Overall, the project is not shown to have a significant impact to the study area. 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 16 4.5 Left Turn Lane Warrant Left turn lanes are a means of providing necessary storage space for left turning vehicles at intersections. For this impact study, procedures prescribed by the WSDOT Design Manual Exhibit 1310-7a were used to ascertain storage requirements at the proposed access locations. Based on forecast 2026 PM peak hour volumes with project traffic – a left turn lane would not be warranted at any of the proposed access intersections. Refer to the appendix for the warrant nomographs. 5. CONCLUSIONS AND MITIGATION MEASURES Cape George BLA proposes for the construction of 70 single-family dwelling units in unincorporated Jefferson County. The subject site is located on the west side of S Discovery Road, situated between Cape George Road and Nelson’s Landing Road. A conceptual site design with proposed accesses is illustrated in Figure 2. In total, approximately 54 AM (13 inbound / 41 outbound) peak hour trips and 72 PM (45 inbound / 27 outbound) peak hour trips are anticipated to travel to/from the development on a daily basis. Existing intersection capacity indicates all intersections of study meeting WSDOT and County level of service standards. A five-year horizon of 2026 was analyzed to assess operations with the project fully- constructed and occupied. With a background growth rate applied, all access and study intersections would continue meeting LOS standards. WSDOT plans for the construction of a roundabout at the intersection of Hwy 20 & Discovery Road to replace the dated traffic signal system. The roundabout would improve capacity and intersection operations and is expected to begin construction in Spring 2023. All proposed project access points are shown to operate with acceptable service levels and left-turn lanes were not warranted at any location. Sight lines may need to be verified upon final site plan and access locations. No operational deficiencies are identified as a result of the proposed development. Based on the analysis above, no off-site mitigation is identified at this time. 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 17 CAPE GEORGE BLA TRAFFIC IMPACT ANALYSIS APPENDIX 2214 Tacoma Road Puyallup WA 98371 (253) 770 1401 Fax (253) 770 1473 heathtraffic.com 18 File Name : 4489a Site Code : 00004489 Start Date : 9/22/2020 Page No : 1 Groups Printed- Passenger + - Trucks Discovery Rd Southbound Discovery Rd (Mill Rd) Westbound S Discovery Rd Northbound Driveway Eastbound Start Time Right Thru Left App. Total Right Thru Left App. Total Right Thru Left App. Total Right Thru Left App. Total Int.
