Daily trip generation rate <br />not available in ITE Trip Generation Manual. Estimated based on 10 times the PM peak hour. <br />3 Based on average rates for ITE Land Use Code 710. <br />4 ITE Trip Generation Manual does not provide in/out split for the AM peak hour; as such, a 50/50 split has been assumed. <br />Based on Table 10 above, the resulting trip generation for the Proposed Project is shown on Table 11. Pass -by <br />reduction assumptions for the shopping center, quality restaurant, and high turnover (sit-down) restaurant uses <br />are consistent with the current ITE Trip Generation Handbook (3rd Edition, 2017). A 5% reduction has also <br />been applied to account for transit mode share, consistent with other projects in the City of Santa Ana. As <br />shown in Table 11, the Proposed Project is estimated to generate 2,792 trip -ends per day with 234 AM peak <br />hour trips and 301 PM peak hour trips. <br />Table 11 Proposed Project Trip Generation Summary <br />Land Use <br />Quantit <br />Units <br />AM Peak Hour <br />PM Peak Hour <br />Dail <br />In <br />Out <br />Total <br />In <br />Out <br />Total <br />Multifamily Housing (High -Rise) (Tower) <br />415 <br />DU <br />35 <br />57 <br />92 <br />55 <br />40 <br />95 <br />896 <br />Office (Tower) <br />190.047 <br />TSF <br />82 <br />13 <br />95 <br />13 <br />69 <br />82 <br />818 <br />Office (Rehabilitated Structures) <br />9.803 <br />TSF <br />10 <br />2 <br />12 <br />2 <br />9 <br />11 <br />96 <br />Shopping Center (Tower & Garage) <br />8.525 <br />TSF <br />5 <br />3 <br />8 <br />16 <br />17 <br />33 <br />322 <br />Pass -by Reduction (PM/Daily: 34%): <br />0 <br />0 <br />0 <br />-5 <br />-5 <br />-10 <br />-110 <br />Shopping Center Total: <br />5 <br />3 <br />8 <br />11 <br />12 <br />23 <br />212 <br />Quality Restaurant (Tower) <br />15.915 <br />TSF <br />6 <br />6 <br />12 <br />83 <br />41 <br />124 <br />1,334 <br />Pass -by Reduction (PM/Daily: 44%): <br />0 <br />0 <br />0 <br />-18 <br />-18 <br />-36 <br />-588 <br />Quality Restaurant Total: <br />6 <br />6 <br />12 <br />65 <br />23 <br />88 <br />746 <br />High Turnover (Sit Down) Restaurant <br />(Rehabilitated Structures) <br />2.681 <br />TSF <br />15 <br />12 <br />27 <br />16 <br />10 <br />26 <br />302 <br />Pass -by Reduction (PM/Daily: 43%): <br />0 <br />0 <br />0 <br />-4 <br />-4 <br />-8 <br />-130 <br />Apri12020 Page 83 <br />
