Item 24 - Public Hearing for Amendments to the Transit Zoning Code

Home Browse Search

The City determined that impacts related to archaeological resources (Impact 4.4-1) unique paleontological resources (Impact 4.4-2), and disturbing human remains were less than significant with the implementation of mitigation measures. Impacts related to historical resources (Impact 4.4-3) were found to be significant and unavoidable and that specific economic, social, or other considerations make infeasible additional mitigation. Specifically, no additional feasible mitigation measures exist that would avoid or substantially reduce these impacts. The TZC EIR states that there are 80 designated historic properties that are listed on the Santa Ana Register of Historical Properties, five that are listed on the California Points of Historical Interest, and one that is listed on the California Historical Landmarks within and adjacent to the TZC area. The TZC area has already been subject to extensive disruption from previous development and may contain artificial fill materials. The proposed adoption of the text regulations identified in Table 1 — Current and Proposed Text Regulations would not require preparation of a supplemental or subsequent EIR because specific development projects are neither included nor required, nor would the project introduce new land uses that would have impact to cultural or tribal cultural resources that could otherwise make the long-term significant and unavoidable historical resource impacts more severe. Any future development within the TZC area requiring discretionary action would continue to be subject to a project -level CEQA review at the time an application is filed for an individual project. In addition, compliance with the existing regulations and proposed amendments will assure that potential impacts are not exacerbated. Mitigation measures MM4.4-1(a), MM4.4-1(b), MM4.4- 2(a), MM4.2(b), and MM4.4-3 would continue to apply. In addition, compliance with the existing regulations and proposed regulations identified in Table 1 — Current and Proposed Text Regulations will assure that potential impacts are not exacerbated, which will result in a beneficial impact to cultural resources. Therefore, the project does not trigger new cultural or tribal cultural resource impacts requiring the preparation of a subsequent or supplemental EIR. There would be no new or more severe significant impacts to cultural and tribal cultural resources. 5.5 HAZARDS AND HAZARDOUS MATERIALS This section analyzes the effects to hazards and hazardous materials from implementing the proposed zoning code regulations. Would the project: a. Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? b. Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? c. Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one -quarter mile of an existing or proposed school? d. Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? e. For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area?
