<br />June 2017 4-1 <br /> <br /> <br /> <br />4.0 Traffic Forecasts <br />Traffic Forecast Scenarios <br /> <br />To adequately address the impacts of the proposed project, forecasts and analyses were <br />completed for the year 2020. Specifically, weekday a.m. and p.m. peak hour traffic <br />forecasts were completed for the following scenarios: <br /> <br />• 2017 Existing. Turn movement volumes collected in May 2017 were used for <br />existing conditions. The existing volume information includes trips generated by <br />uses near the project site. <br /> <br />• 2020 No-Build. Existing volumes at the subject intersections were increased by 1.0 <br />percent per year to determine 2020 No-Build volumes. The 1.0 percent per year <br />growth rate was based on recent historic traffic volume growth in the project area. <br /> <br />• 2020 Build. Trips generated by the proposed use were then added to the 2020 No- <br />Build volumes to determine 2020 Build volumes. <br /> <br />Trip Generation-Proposed Project <br /> <br />The expected new development trips were calculated based on data presented in Trip <br />Generation, Ninth Edition, published by the Institute of Transportation Engineers. These <br />calculations represent total trips that will be generated by the proposed development. <br /> <br />The resultant trip generation estimates are shown in Table 4-1. <br /> <br />Table 4-1 <br />Weekday Trip Generation for Proposed Apartment Building <br /> <br />Land Use <br /> <br />Size <br />Weekday AM Peak Hour Weekday PM Peak Hour Weekday <br />Daily <br /> In Out Total In Out Total Total <br />Proposed <br />Apartments 60 DU 6 25 31 24 13 37 399 <br /> <br />Net Total 6 25 31 24 13 37 399 <br />Notes: DU=dwelling units <br /> <br />As shown in Table 4-1, the proposed development will add a net total of 31 trips during the <br />a.m. peak hour, 37 trips during the p.m. peak hour, and 399 trips on a daily basis. <br /> <br />
