5. Environmental Analysis TRAFFIC AND CIRCULATION Roadway Segments • North Grand Avenue between Fairhaven Avenue and Santa Clara Avenue; • North Grand Avenue between Santa Clara Avenue and 17th Street; • Lincoln Avenue between Fairhaven Avenue and Santa Clara Avenue; • Lincoln Avenue between Santa Clara Avenue and 1 7th Street; • Fairhaven Avenue between North Grand Avenue and Lincoln Avenue; • Santa Clara Avenue between North Grand Avenue and Lincoln Avenue; • 17th Street between North Grand Avenue and Lincoln Avenue Intersections • Lincoln Avenue and Fairhaven Avenue no control) • Lincoln Avenue and Santa Clara Avenue/ Aspen Street (all -way stop); • Lincoln Avenue and 17th Street (signalized); • North Grand Avenue and Fairhaven Avenue (signalized); • North Grand Avenue and Santa Clara Avenue (signalized); • North Grand Avenue and 17th Street (signalized) These intersections and roadway segments were identified because of their proximity to the site and their role in circulation within and around the project area. Because the intersection of Lincoln Avenue and Fairhaven Avenue operates as an "L" configuration and requires no vehicle traffic control, intersection delay analysis is not warranted. Intersection geometries for existing study area roadways (the Fairhaven /Lincoln intersection is currently closed) are shown in Figure 5.3-1, Intersection Geometries — Intersection Open. Traffic Terminology and Methodology Roadway Segments Roadway segment standards provide the basis to screen roadway segments with high traffic volumes that may result in the need for more detailed analysis. The City of Santa Ana Circulation Element lists the roadway classifications and capacity standards from which volume to capacity (V /C) relationships can be derived. Table . -1 list the City of Santa Ana's roadway segment capacity standards. For this study, a capacity of 10,000 vehicles per day was used for Lincoln Avenue, Fairhaven Avenue, and Santa Clara Avenue, and a capacity of 50,600 vehicles per day was used for 17th Street, which is a major arterial.
