Transportation Impact Study for Hidden Canyon Residences & Preserve March 2023 Page | 11 1.4 ANALYSIS SCENARIOS This study assesses potential impacts based on the following six scenarios: • Existing Conditions – This scenario describes existing transportation conditions relevant to the study area, including characteristics of key roadways and transit service, existing conditions for walking and bicycling, a summary of report collision data near the project site. • Existing plus Project Conditions – This scenario describes the anticipated effects of the proposed project on Existing Conditions, including the addition of traffic from the proposed project to study intersections. • Near Term No Project Conditions – This scenario is similar to Existing Conditions (without the proposed project) but with the addition of motor vehicle traffic from approved and pending developments within the vicinity of the proposed project that would affect traffic operations at study intersections. • Near Term Plus Project Conditions – This scenario evaluates the effect of the proposed project on near term transportation conditions, including the effect on LOS at each study intersection. • Cumulative No Project Conditions – This scenario describes anticipated transportation conditions with buildout of General Plan land uses and transportation improvements, but without the proposed project. • Cumulative Plus Project Conditions – This scenario describes anticipated transportation conditions with buildout of the General Plan land uses that includes the proposed project, and with the anticipated transportation improvements that would accompany buildout. Cumulative impacts resulting from the project are assessed based on the net change from Cumulative No Project Conditions.
