The full site trip distribution for Opening Year (2030) Scenario 2 is shown in Exhibit 13. The site traffic assignment, representing traffic volumes associated with the proposed development at the study intersections, is a function of the estimated trip generation (Table 5-1 and Table 5-2) and the directional distribution listed above. The site trip assignment for Opening Year (2030) Scenario 2 is shown in Exhibit 14. The Opening Year (2030) Build traffic volumes were calculated by adding the total Development Site Trips (Exhibit 14) to the Opening Year (2030) No -Build traffic volumes (Exhibit 5). The Opening Year (2030) Build traffic volumes are shown in Exhibit 15. The Design Year (2045) Scenario 2 site traffic distribution is shown in Exhibit 16. The site trip assignment for Scenario 2 in the Design Year (2045) is shown in Exhibit 17. The Design Year (2045) Build traffic volumes were calculated by adding the total Development Site Trips (Exhibit 17) to the Design Year (2045) No -Build traffic volumes (Exhibit 6). The Design Year (2045) Build traffic volumes are shown in Exhibit 18. 5.4. OPENING YEAR (2030) SCENARIO 2 CAPACITY ANALYSIS The Opening Year (2030) Scenario 2 conditions analysis was conducted to determine the impacts of the proposed development on the short-term operations of the adjacent roadway network. The future year (2030) geometry and intersection control changes discussed in §3.1. All site access points were assumed to be side street stop controlled for the analysis. The Opening Year (2030) Scenario 2 traffic volumes are shown in Exhibit 14. The results of the Opening Year (2030) Scenario 2 conditions analysis is shown in Table 5-2. Based on the results of the Opening Year (2030) Scenario 2 conditions analysis, all intersections are anticipated to operate at LOS C or better and all individual movements are anticipated to operate at LOS D or better during the AM and PM peak hours. Comparing the delay and LOS results to the Opening Year (2030) No -Build scenario indicates that the proposed development Scenario 2 is anticipated to cause some increases in delay, with the Main Street & Lake Drive and Main Street & 4th Avenue intersections seeing the most substantial increases. All delays remain within an acceptable range and the overall traffic operations of the network remain acceptable with the anticipated Opening Year (2030) geometric changes in place. With operations remaining acceptable in Opening Year (2030) build Scenario 2, an east -west roadway connection on the south half of the AUAR site is not required from a traffic operations perspective, however, the connection of Robinson Drive (Access E) would help improve connectivity to the neighborhoods. The connection of Carl Street is not necessary from a traffic operations perspective. The 95th percentile queueing results were reviewed and all 95th percentile queues are expected to remain within their provided storage bays. SimTraffic reports are included in Appendix B.
