Transportation Impact Study for Hidden Canyon Residences & Preserve March 2023 Page | 36 5.0 NEAR TERM CONDITIONS The analysis of potential project impacts under near-term conditions is based on the addition of additional traffic from approved and pending developments that would generate additional traffic on study area roadways. 5.1 NEAR TERM TRAFFIC VOLUMES City staff provided the anticipated traffic volumes under Near Term No Project conditions based on outputs from the City’s travel demand model. Forecasted peak-hour traffic volumes at each study intersection under Near Term No Project Conditions are shown on Figure 12. Traffic volumes at each study intersection under Near Term plus Project conditions is based on the addition of project trips to each study intersection with no changes to lane configurations. Trip generation and distribution for the proposed project are identical to that assumed under Existing plus Project Conditions. Figure 13 displays projected peak hour turning movement volumes at all of the study intersections for Near Term plus Project Conditions. 5.2 NEAR TERM IMPACT FINDINGS WITH PROPOSED PROJECT Detailed LOS reports for both of the near-term scenarios are contained in Appendix D and Appendix E. The intersection LOS analysis results under both Near Term No Project and Near Conditions are summarized in Table 7. All intersections would operate at an acceptable LOS D or better under Near Term No Project and Near Term plus Project Conditions based on overall average delay to all approaches. During the a.m. peak hour the stop-sign controlled intersection of Schaefer Ranch Road & Dublin Canyon Road experiences would experience delay consistent with LOS F on the stop-sign controlled approach (southbound Schaefer Ranch Road approaching Dublin Canyon Road) under both Near-Term No Project and Near-Term plus Project conditions. Side-street approach volumes on Schaefer Ranch Road exceed the peak-hour signal warrant based on volume under Existing Conditions and would continue to do so under Near-term Conditions with or without the proposed project. Average delay to the stop-sign controlled approach would increase by less than one second due to the project. Therefore, the project would not increase delay to a minor movement at an unsignalized intersection operating at LOS F by more than 30 seconds. The project is not anticipated to add traffic to the controlled approach. Overall average delay for the intersection would remain consistent with LOS A. With installation of a traffic signal at the intersection of Dublin Canyon Road with Canyon Meadows Drive (which is being coordinated between the developer and the City to enhance traffic operations and safety), the intersection is expected to continue to operate at LOS A during both peak hours. Near-term traffic impacts resulting from the project would be considered less than significant based on City standards.
