® PLACEWORKS <br />Government Code Section 65915 (f)(5) granting a density bonus shall not require a general plan <br />amendment. The zoning for the Project Site is Downtown (DT) Zone of the Transit Zoning Code (SD <br />84). This zone allows for multi -story urban building types accommodating a mixture of retail, office, <br />light service, and residential uses. Within this zone, Flex Block building types are allowed up to a <br />maximum of 10 stories. One of the goals of the DTZone is to replace parking structures with other <br />compatible pedestrian friendly uses. The Proposed Project would replace a 3-level parking garage <br />with a mixed -use building containing 171 units and 13,419 square feet of commercial space, making <br />it consistent with the goals outlined for the DTZone. Of the 171 residential units, 19 will be reserved <br />for very low income households for a period of 55 years. The Proposed Project would require an <br />approval of a Density Bonus Agreement Application with a waiver to allow a floor area ratio of 4.2, <br />development up to 16-stories, concessions to allow deviations to the open space and massing <br />requirements, and provide parking at a rate of one space per studio and one bedroom and two <br />spaces per two bedroom units <br />0-8 Please refer to Responses 0-5 and 0-7. Additionally, as indicated in the Addendum and discussed <br />in the Certified EIR, development of the Proposed Projectwould incrementally increase the demand <br />for fire protection services, but would not result in a significant impact with implementation of <br />mitigation identified in the Certified EIR. Contrary to the Commenter's suggestion, the Proposed <br />Project would not result in any unique firefighting challenge that exceeds the capability of the <br />Orange County Fire Authority. The Orange County Fire Authority reviewed the plans as part of the <br />site plan review process. Appropriate Fire Facility fees would be assessed during review of <br />development plans. The obligation of the Proposed Project to meet all access, water and fire <br />protection systems required under the California Building Code and Fire Code, as well as the City <br />Municipal Codes will assist in maintaining impacts that are less than significant. <br />0-9 Analysis of potential excessive groundborne vibration or groundborne noise levels during <br />construction is provided beginning on Page 109. A project design feature has been developed to <br />protect adjacent structures, as follows: <br />"If pile driving and/or drilling is necessary during Project construction, a site -specific analysis shall <br />be prepared and submitted to the City of Santa Ana demonstrating that construction activity would <br />not result in vibration at sensitive receiver locations, and/or adjacent buildings, that is greater than <br />the Federal Transit Administration's vibration impact thresholds appropriate for each building <br />(consistent with TZC EIR thresholds); unless otherwise determined by a qualified engineer that high <br />levels of ground -borne vibration would not post structural hazards to the adjacent building(s). The <br />engineer shall provide written documentation that shall include the applicable construction <br />vibration threshold and expected or monitored vibration levels during pile driving and/or drilling <br />activity to the City of Santa Ana building department." <br />Based on the analysis in the Addendum, no impacts to adjacent structures during construction are <br />anticipated. <br />0-10 Please refer to Responses 0-2 and 0-5 for a discussion of parking. As noted above the Proposed <br />Project is located in a Transit Priority Area (TPA) and therefore, aesthetic and parking impacts cannot <br />be considered a significant impact. <br />0-11 Please refer to Response 0-7 above. <br />0-12 As discussed in Section 5.11, Land Use and Planning, the Proposed Project is the type of mixed -use <br />development envisioned by the Transit Zoning Code. The Project Site's existing General Plan <br />designation is District Center (DC), intended to be "developed with an urban character that includes <br />75A-479 November 2020 1 Page 6 <br />
