2525 North Main Street January 14, 2019 Page 17 Traffic A Traffic Impact Analysis was prepared by Translutions, Inc. for the project. The study was peer reviewed by the Citys Public Works Agency and Kimley‐Horn an on‐call traffic engineering firm The study evaluated 16 intersections, 10 roadway segments, 6 neighborhood intersections, 10 neighborhood roadway segments and 15 freeway segments (DEIR Section 4.1 1). Impacts were analyzed for the existing conditions (2018), expected project opening year (2020) and future conditions (2040). The 2020 conditions include the planned Caltrans improvement project which will add one continuous High Occupancy Vehicle (HOV) lane in each direction along the northbound and southbound I‐5 freeway between SR‐55 and SR‐57, which would result in the removal of the I‐5 HOV northbound entrance and southbound exit ramps at the intersection of N. Main Street/Edgewood Road I‐5 ramps. Based on the Institute of Traffic Engineers (ITE) trip generation rates, the project is estimated to generate 2,698 daily trips.

The LOS criteria uses an "A" to "F" rating scale; an "A" rating meaning traffic conditions have the least amount of traffic congestion (free flowing traffic) and an "F" rating meaning traffic conditions will have the most traffic congestion (forced or breakdown of traffic flow). As a standard practice, the City has adopted an operational LOS rating of D as the minimum acceptable LOS for intersections and roadway segments, except that for intersections and roadway segments that fall within major development areas, the City adopted a LOS rating of E as the minimum acceptable LOS. LOS is obtained by calculating the ratio of vehicles at an intersection or roadway segment versus the vehicle capacity of that intersection or roadway segment (Vehicles/Capacity). The City acknowledges that the proposed project would generate additional traffic and that would result in an increase in vehicle trips on area roadways (2,698 trips). However, the project and implementation of any of the three access options would not exceed a threshold identified by the City or Caltrans (Pages 4.11‐12 to 4.11‐23 of the DEIR).
