Mitigation Measures <br />MM-OZ 4.6-1 For future residential uses that are developed under the Overlay Zone within <br />500 feet of an existing freeway, a health risk assessment (HRA) for diesel <br />exhaust shall be prepared. Recommendations contained within the HRA shall <br />be implemented in project design. <br />MM-OZ 4.6-2 Prior to the issuance of grading permits on any project site, the site <br />• Investigate the project site to determine whether it or immediately <br />adjacent areas have a record of hazardous material contamination via <br />the preparation of a preliminary environmental site assessment (ESA), <br />which shall be submitted to the City for review. If contamination is found <br />the report shall characterize the site according to the nature and extent <br />of contamination that is present before development activities precede <br />at that site. <br />• If contamination is determined to be on site, the City, in accordance <br />with appropriate regulatory agencies, shall determine the need for <br />further investigation and/or remediation of the soils conditions on the <br />contaminated site. If further investigation or remediation is required, it <br />shall be the responsibility of the site developer(s) to complete such <br />investigation and/or remediation prior to construction of the project. <br />• If remediation is required as identified by the local oversight agency, it <br />shall be accomplished in a manner that reduces risk to below applicable <br />standards and shall be completed prior to issuance of any occupancy <br />permits. <br />MM-OZ 4.6-3 In the event that previously unknown or unidentified soil and/or groundwater <br />contamination that could present a threat to human health or the environment <br />is encountered during construction of the proposed project, construction <br />activities in the immediate vicinity of the contamination shall cease <br />immediately. If contamination is encountered, a Risk Management Plan shall <br />be prepared and implemented that (1) identifies the contaminants of concern <br />and the potential risk each contaminant would pose to human health and the <br />environment during construction and post -development and (2) describes <br />measures to be taken to protect workers, and the public from exposure to <br />potential site hazards. Such measures could include a range of options, <br />including, but not limited to, physical site controls during construction, <br />remediation, long-term monitoring, post -development maintenance or access <br />limitations, or some combination thereof. Depending on the nature of <br />contamination, if any, appropriate agencies shall be notified (e.g., City of Santa <br />Ana Fire Department). If needed, a Site Health and Safety Plan that meets <br />Occupational Safety and Health Administration requirements shall be prepared <br />and in place prior to commencement of work in any contaminated area. <br />Cabrillo Town Center City of Santa Ana <br />Technical Memorandum August 2023 <br />City Council 18 — 577 10/3/2023 <br />
