The proposed restaurant will be approximatley 2,300 square feet in size. Figure 1 illustrates the site vicinity and the transportation network serving the project area. This Traffic Scoping Analysis estimates the trip generation, distribution, and assignment for the proposed development. Figure 1. Site Vicinity Yelm Popeyes Traffic Scoping Analysis 2020-1214 | 2 of 4 Proposed Development The proposed project would construct a new approximate 2,300-square foot Popeyes restaurant on a lot previously occupied by a used automobile dealership in Yelm. The site has an existing approximate 500-square foot structure that will be removed. The project site currently provides two access points, one on Yelm Avenue and one on Morris Road. The project proposes to use the current driveway on Yelm Avenue and relocate the driveway on Morris Road just south of the existing access. The preliminary site plan is attached. The project is anticipated to open in 2021. Project Traffic Characteristics The two project-related characteristics having the most effect on area traffic conditions are peak hour trip generation and the directional distribution of traffic volumes on the surrounding roadway network. These are discussed in the following paragraphs. Site-Generated Traffic Volumes Vehicle trip generation was estimated using the trip generation rates contained in the 10th edition of the Trip Generation Manual by the Institute of Transportation Engineers (ITE). The land-use category “Fast-Food Restaurant with Drive-Through Window” (land-use code 934) with the variable 1,000-sf was determined to be the most applicable to this project. The land use category “Automobile Sales (Used) (land-use code 841) was used to estimate trips for the auto dealership previously on the site. Pass-By It is anticipated that this project will attract some traffic from people already driving on adjacent roadways. These trips are not new trips added to the local roadway system (primary trips) but represent “pass-by” trips according to the following definition: Pass-by trips: Pass-by trips are trips made as an intermediate stop from an origin to a primary destination (i.e., stopping to shop on the way home from work) by vehicles passing directly by the project driveway. The pass-by percentage contained in the 3rd edition of the Trip Generation Handbook by ITE were used for the proposed Popeyes restaurant, with an AM Peak hour rate of 49% and a 50% rate for the PM Peak hour. Given the small volume of traffic using the dead-end portion of Morris Road to which the site driveway connects, all of the pass-by traffic was assigned to the driveway on Yelm Avenue E. Given that this driveway does not allow left-turns to exit the site, and the presence of peak period congestion at the adjacent traffic signal, all of the pass-by trips were assigned to the eastbound travel direction. No pass-by trips were assumed for traffic traveling in the westbound direction. The trip generation rates used for the AM peak hour and PM peak hour trip are shown in Table 1.

The model uses the Emme/4 software package and has been calibrated to represent the existing vehicle travel patterns throughout the entire county. Yelm Popeyes Traffic Scoping Analysis 2020-1214 | 4 of 4 Using the model, a Select Zone Analysis (SZA) was conducted for Transportation Analysis Zone (TAZ) #716, which represents the project site. This feature of the Emme/4 software package allows all of the traffic into and out of a particular zone to be isolated and shown separately from the rest of the traffic on the network. The SZA graphically shows the percentage of vehicles currently using each of the available routes into and out of the area (Yelm Avenue and Bald Hill Road). From this information, regional distribution percentages were calculated for future traffic from the proposed Popeyes project. The regional traffic distribution percentages and site traffic distribution for the PM peak hour are shown on Figure 2. The select zone analysis plot is attached.
