City of Santa Ana Addendum to the <br />MainPlace Mall Transformation Proiect Fashion Square Commercial Center Final EIR <br />In addition, improvements planned as part of the Santa Ana Freeway Interstate 5 (1-5) <br />High Occupancy Vehicle (HOV) Lane Improvement Project between SR-55 to SR-57 <br />will provide one additional HOV lane in each direction to provide additional HOV <br />capacity and reduce freeway congestion. As a part of the HOV improvements, the <br />southbound off -ramp and northbound on -ramp HOV structures at the intersection of <br />Main Street at Edgewood Road would be removed. This would result in a redistribution <br />of local traffic through nearby streets and intersections. However, the HOV <br />improvements would not substantially impact any of the analyzed intersections, and no <br />locations would be negatively affected by elimination of the Main Street direct HOV <br />ramps (TIS 2019). <br />Project Trip Generation <br />Daily and peak hour trips for the proposed Project were estimated using the Institute of <br />Transportation Engineers (ITE) Trip Generation Manual (10th Edition), which are listed <br />in Table T-3. <br />Table T-3: Trip Generation Rates <br />Land Use <br />ITE Code <br />Unit <br />Trip Generation Rates' <br />AM Peak Hour <br />PM Peak Hour <br />Daily <br />In <br />Out <br />Total <br />In <br />Out <br />Total <br />Shopping Center <br />820 <br />KSF <br />37.750 <br />0.583 <br />0.36 <br />0.940 <br />1.829 <br />1.981 <br />3.81 <br />General Office <br />Building <br />710 <br />KSF <br />9.740 <br />0.998 <br />0.16 <br />1.160 <br />0.184 <br />0.966 <br />1.15 <br />Hotel <br />310 <br />Room <br />8.360 <br />0.277 <br />0.19 <br />0.470 <br />0.306 <br />0.294 <br />0.60 <br />Multi -family Housing <br />(Mid -Rise) <br />221 <br />DU <br />5.440 <br />0.094 <br />0.266 <br />0.360 <br />0.268 <br />0.172 <br />0.440 <br />Source: Traffic Impact Study, 2019 <br />'ITE Trip Generation Manual, 10" Edition <br />As shown on Table T-4, the proposed Project is estimated to generate 31,178 daily <br />vehicle trips, with 1,996 trips in the a.m. peak hour and 2,968 trips in the p.m. peak <br />hour. Table T-3 also provides the trips associated with the existing development on the <br />Project site (1,130,000 sf of commercial development), the total estimated trip <br />generation for the existing development on the site plus the proposed Project, and <br />adjustments for internal capture and pass -by trips. <br />
