CITY OF SANTA ANA ENVIRONMENTAL SERVICES I TRAFFIC MAY 21, 2007 • Conduct a site visit to observe existing traffic conditions at the project site and the study roadways and intersections surrounding the site. The Existing Conditions section of the report will identify mid -block lane configurations on all roadway segments between study intersections, intersection lane geometry and controls, and all existing bicycle, pedestrian, transit, and public parking facilities. • Report exhibits will be prepared to present existing traffic, transit, and pedestrian conditions in visual form. • Obtain morning and evening peak hour traffic turning movement count data at the study intersections, and directional 24-hour traffic data on the study roadway segments. • Develop project trip generation estimates for the proposed project, using the Institute of Transportation Engineers (ITE) publication Trip Generation (7th Edition). The project is assumed to build out in a single phase. Trip generation estimates will include adjustments for pass -by factors, on -site trip capture, and alternative travel modes, as appropriate. • Develop trip distribution assumptions for the project traffic, based on familiarity with the project area, and likely origins and destinations of site residents or visitors. Project traffic will be distributed to the study roadway segments and through the study intersections and the project traffic contribution to each will be identified. • The trip generation and trip distribution assumptions and analysis methodology will be presented to City staff for review and concurrence prior to proceeding with the analysis phase of the study. • Work with City Planning staff to identify approved and pending projects (including all proposed and reasonably foreseeable projects) and ambient growth rates, to develop Cumulative Conditions traffic forecasts for the Project Opening Year. • Obtain OCTAM peak hour and daily Build -out forecast data from the OCTA. Using forecasted approach volume data, develop build -out peak hour forecasts for the study intersections and daily forecast data for roadway segments. • Conduct roadway and intersection analysis and summarize operating conditions on the study roadways segments and at the study intersections for the following scenarios: - Existing Conditions (2007) - Opening Year (Cumulative Conditions) without Project - Opening Year with Project - Opening Year with Project with Mitigation (if needed) - General Plan Build -out without Project - General Plan Build -out with Project - General Plan Build -out with Project with Mitigation (if necessary) • Intersections will be analyzed using the City of Santa Ana Intersection Capacity Utilization (ICU) methodology, except that Caltrans-controlled intersections and unsignalized intersections will be analyzed using the Highway Capacity Manual (HCM) delay methodology.
