usumt-11-r Settler's Pointe Development—Traffic Impact Analysis Q � Also, an analysis was conducted at the Service Road intersection at Old NC 86 for the 2020 Build Analysis; however, since trip generation practices only provide peak hour turn movements, the only data available for a warrant analysis was for AM and PM peak hours. For this intersection, the 2020 Build volumes generated by the proposed site were utilized for the AM and PM peak hour traffic. Data was not formally collected at this intersection with the other study intersections, but the turn counts collected at the nearby 1-40 eastbound ramps were provided via a video recording, and a review of the video indicated that there were no peak hour turn movements in or out of the Service Road. The Service Road provides public street access to tracts of land that are presently vacant, so this is a reasonable conclusion. Using HCS with 2020 projected traffic conditions, the intersection of Old NC 86 at the Service Road met the following signal warrants: ■ Warrant 3B: Peak Hour (Peak-Hour Vehicular Volumes) • Warrant 6: Coordinated Signal System In similar fashion, the 2022 Build volumes generated by the proposed site were utilized for the AM and PM peak hour traffic for the following intersections: ■ Old NC 86 and proposed Retail Drive ■ Old NC 86 and Davis Road Peak hour (AM and PM) turn movement count data was collected for the Davis Road and Old NC 86 intersection on the same day as the other study intersections, October 18, 2016. The existing turn movement counts were then grown out to 2022 using a 1% annual growth rate, and the proposed trips generated by the residential retirement driveway connection to the existing intersection added to form the basis for the AM and PM count data. For the proposed retail driveway, the projected volumes for the through movements represent the 2022 background traffic, plus the trips generated by the site itself. Similar to the scenario with the Service Road, the only data used for the warrant analysis at the Retail Drive intersection and Davis Road intersection warrant analysis was the peak hour turn movement counts. Using HCS with 2022 projected traffic conditions, the intersection of Old NC 86 at the Retail Drive met the following signal warrants: ■ Warrant 313: Peak Hour (Peak-Hour Vehicular Volumes) ■ Warrant 6: Coordinated Signal System Additionally, the intersection of Old NC 86 at Davis Road met the following signal warrant: ■ Warrant 3B: Peak Hour (Peak-Hour Vehicular Volumes) HCS reports for the signal warrant analysis are located in Appendix D. 60
