3. Forecasted Traffic a. Site Traffic Forecasting The Institute of Transportation Engineers (ITE) provides the Trip Generation Manual, 9t" Edition, the standard document for determining expected traffic for proposed land uses. Using this ITE information, trip generation forecasts can be made for the development site. The ITE manual compiles studies from across the country to provide a national average traffic for various land uses. For the proposed residential development, the designation of Single Family Homes and Townhomes were used. Based on information supplied in the site plan, the development is currently proposed to include 98 townhomes and 246 single family homes for a total of 344 units. With this information, the expected trip generation was completed based on the full build out of the development. The resultant new trips generated by the proposed development are shown in Table 2. A detailed trip generation table showing the exact breakdowns is provided in the Appendix.

This pattern is based on the existing traffic volumes, access locations, location of major roadways leading to and from the site, and prior studies within the project area. The general trip distribution pattern for this study is: i. 22 percent of the site generated traffic to/from the west on Alpine Drive. ii. 78 percent of the site generated traffic to/from the east on Alpine Drive and Bunker Lake Boulevard. Traffic generated by the development of the site was assigned to the area roadways per this distribution pattern. b. Non-site Traffic Forecasting To forecast future traffic volumes for the year 2040 in the study area outside of the proposed development's traffic, additional trip generations were considered based on proposed developments within the project area. These trip generations were based on a prior study completed by Bolton & Menk analyzing the Future Traffic Impact Study 3 CONSULTING Pearson Farm Residential Development
