5.0 Supplemental Analysis of the Project Revisions
Alternative include a change of a zone from a Greenway Zone to Urban Innovation Zone for Block 52. The transportation impacts due to the designation of Block 52 under the Urban Innovation Zone were already compared relative to the Original Proposed Alternative in Section 17.6.3 and Table 17-3 of the Original DEIR, see Modified Project Alternative discussion above. The Original DEIR concluded that the Modified Project Alternative would result in a minor increase in transportation impacts due to additional land use intensity, but would not result in a new significant impact. In addition, Block 52 is located in the River Buffer Area and would still be limited to the same 1.5:1 FAR as applied in the Greenway Zone indicating that increases in land use intensity as the result of this change would be associated with the use rather than the intensity of use. However, according to the Institute of Transportation Engineers (ITE), Trip Generation manual, 8th edition, 2008 (ITE manual) the Greenway Zone would also permit relatively high traffic generating uses such as restaurants, as compared to the uses permitted in the Urban Innovation Zone such as industrial and ancillary office uses. 2 In addition, the industrial and ancillary office uses would have greater participation in transit ridership than some of the uses allowed in the Greenway Zone since transit usage rates are generally shown to comprise higher work-related trips than recreational trips. Furthermore, application of TDM strategies included as Mitigation Measure Transportation 1 would apply to most uses allowed in the Urban Innovation Zone which would further reduce potential impacts resulting from the change in designation. LADOT typically awards a trip reduction credits based on transit supportive features and mixed use strategies. 3 This change will not result in a new significant transportation impact or result in a substantial increase in the severity of an existing transportation impact as previously evaluated in the Original DEIR. The Revised Proposed Alternative also expands the uses in the Urban Innovation Zone for specific blocks to include the Entertainment, Exhibit and Cultural use category as an ancillary use restricted to Block 52, and Religious Institutions use category restricted to Blocks 50/51. Under the Original Proposed Alterative, the proposed Urban Innovation Zone would allow principal uses that include light manufacturing and assembly, research and development, while ancillary uses that include commercial office, restaurants and other retail would be allowed in the same zone. The ITE manual provides some data on entertainment uses such as multiplex movie theatres, though the type of entertainment uses that would be approved as ancillary use in Block 52 would be of a more limited nature such as live theatre or one or two screen movie theatre. It should also be noted of the periodic nature of events for the entertainment and cultural uses that would be permitted for Block 52 of the Revised Proposed Alternative as compared to the other uses that they would replace. Further, the land use revision to Block 52 is consistent with the current use of the property that includes a community theatre.

According to the ITE manual, a full service sit down restaurant (Land Use Code 932) will generate an average of 18.49 trips per 1,000 sf week day P.M. peak hour generator trips while the corresponding week day P.M. peak hour generator trips for light industrial (Land Use Code 110), single tenant office (Land Use Code 715), and (Land Use Code 220) are 1.08 trips per 1,000 sf, 1.73 trips per 1,000 sf, and 0.67 trips per unit respectively.
