EIR No. 2018-01, DA No. 018-01, GPA No. 2018-06, <br />AA No. 2018-10 2525 North Main Street <br />February 5, 2019 <br />Page 16 <br />Traffic <br />A Traffic Impact Analysis was prepared by Translutions, Inc. forthe project. The studywas peer reviewed by <br />the Cltys Public Works Agency and Kimley-Horn an on-call traffic engineering firm .The study evaluated 16 <br />intersections, 10 roadway segments, 6 neighborhood intersections, 10 neighborhood roadway segments <br />and 15 freeway segments (DEIR Section 4.1 1). Impacts were analyzed for the existing conditions (2018), <br />expected project opening year ( 2020) and future conditions (2040). The 2020 conditions include the planned <br />Caltrans improvement project which will add one continuous High Occupancy Vehicle (HOV) lane in each <br />direction along the northbound and southbound 1-5 freeway between SR -55 and SR -57, which would result <br />in the removal of the 1-5 HOV northbound entrance and southbound exit ramps at the intersection of N. <br />Main Street/Edgewood Road 1-5 ramps. Based on the Institute ofTraffic Engineers (ITE) trip generation rates, <br />the project is estimated to generate 2,698 daily trips. <br />Table 8: Proposed Project Trip Generation <br />AM Peak our PM Peak Hour <br />7:00 to 9:00 a.m. 4:00 to 6:00 p.m. <br />Land Use <br />In <br />Out <br />Total <br />In <br />Out <br />Total <br />Daily <br />Trip Generation <br />0.09 <br />0.27 <br />0.36 <br />0.27 <br />0.17 <br />0.44 <br />5.44 <br />Rates <br />Proposed Project <br />46 <br />133 <br />179 <br />133 <br />86 <br />219 <br />2,698 <br />Trip Generation <br />(496 units) <br />Existing Office <br />81 <br />13 <br />94 <br />15 <br />79 <br />94 <br />791 <br />(Alternative 1) <br />_ <br />Reduced Project <br />32 <br />93 <br />125 <br />93 <br />60 <br />153 <br />1,888 <br />(Alternative 2) <br />Office -Professional <br />387 <br />62 <br />449 <br />71 <br />375 <br />446 <br />3,774 <br />zone (Alternative 3) <br />The City of Santa Ana uses a rating criteria known as Level of Service (LOS) to assess the severity of traffic <br />congestion at intersections and roadway segments. The LOS criteria uses an "A" to "F" rating scale; an "A" <br />rating meaning traffic conditions have the least amount of traffic congestion (free flowing traffic) and an "F" <br />rating meaning traffic conditions will have the most traffic congestion (forced or breakdown of traffic flow). <br />As a standard practice, the City has adopted an operational LOS rating of D as the minimum acceptable LOS <br />for intersections and roadway segments, except that for intersections and roadway segments that fall within <br />major development areas, the City adopted a LOS rating of E as the minimum acceptable LOS. LOS is <br />obtained by calculating the ratio of vehicles at an intersection or roadway segment versus the vehicle <br />capacity of that intersection or roadway segment (Vehicles/Capacity). <br />The City acknowledges that the proposed project would generate additional traffic and that would result in <br />an increase in vehicle trips on area roadways (2,698 trips). However, the project and implementation of any <br />75E-16 <br />
