City of Santa Ana Environmental Checklist Minimum V/C or Delay Key Intersection' Acceptable LOS Control Type (seconds)' LOS Sullivan Street at McFadden Avenue D Traffic Signal 01519 A Notes: Minimum 1. Signalized Intersection. V/C for Intersections based on application of Intersection Capacity Utilization methodology using Traffix software. V/C = volume / Capacity Ratio. 2. The level of service is provided for the worst case Sunday peak hour (10:15 AM -11:15 AM). A = Project change Acceptable Source: Fehr & Peers, Traffic Impact Analysis, 2012. The traffic impacts of the proposed project during the peak hour were evaluated in the TIA based on the existing plus project traffic conditions at the six study area intersections for the proposed project. Table 3 -21 shows the changes in the performance of the intersections from the addition of project - related traffic generated compared to existing conditions. As shown, both signalized intersections within the study area would continue to operate at acceptable levels with operation of the proposed project in the near -term. There is a potential that traffic volumes may increase above levels presented here during limited special events. However, the volumes are difficult to quantify and would be speculative. Therefore, implementation of Mitigation Measure TT -1 would minimize Impacts traffic impacts associated with special events, and reduce impacts to less than significant levels. Table 3 -21. Existing Plus Project— Peak Hour Intersection Capacity Analysis Neighborhood Impacts A neighborhood impacts analysis was prepared for the proposed project to evaluate potential impacts on the adjacent residential areas due to a potential increase in trips through the adjacent residential neighborhood streets, specifically Monta Vista Avenue, to create a potential neighborhood impact. Project related traffic can potentially use Monta Vista Avenue as a "cut- through" route to avoid delay at upstream signalized intersections, such as the intersection of Willits Street and Sullivan Street or First Street and Sullivan Street. Since Monta Vista Avenue is the first available right turn for northbound traffic, this is a feasible option for northbound traffic exiting the site, Inbound traffic would most likely not access the project site via Monta Vista Avenue since most drivers select their route base on "path of least resistance," which would likely be along First Street, Willits Street or McFadden Avenue. These streets have higher speed limits, more through lanes, more capacity, and contain traffic signals which make them more efficient and desirable routes for inbound traffic.
