MM4.5-3 Prior to the demolition of structures that were constructed before 1980, a thorough investigation shall be completed to determine if asbestos, lead, or PCBs exist on the site. All demolition that could result in the release of lead and/or asbestos must be conducted according to Cal/OSHA standards. (Impact 4.5-2) MM4.5-4 For development of structures that exceed 200 feet in height above ground level at a development site, applicants shall file a Notice of Proposed Construction or Alteration with the FAA (FAA Form 7460-1). Following the FAA's aeronautical evaluation of the project, projects must comply with conditions of approval imposed or recommended by the FAA. Subsequent to the FAA findings, the project shall be reviewed by the ALUC for consistency analysis. (Impact 4.5-5) MM4.5-5 Prior to initiation of construction activities, any development within the Transit Zoning Code (SD 84A and SD 84B) Area shall have a completed traffic control plan, prepared by the project proponent that will be implemented during construction activities. This may include, but is not limited to, the maintenance of at least one unobstructed lane in both directions on surrounding roadways. At any time if only a single lane is available, the developer shall provide a temporary traffic signal, signal carriers (i.e., flagpersons), or other appropriate traffic controls to allow travel in both directions. If construction activities require the complete closure of a roadway segment, the developer shall provide appropriate signage indicating alternative routes. (Impact 4.5-6) MM4.5-6 The City Public Works Department shall consult with the Santa Ana Police Department and the Santa Ana Fire Department to disclose temporary closures and alternative travel routes in order to ensure adequate access for emergency vehicles when construction of future projects would result in temporary land or roadway closures. (Impact 4.5-6) MM4.6-7 The Santa Ana Fire Department, in consultation with other applicable City Departments (e.g., Police), shall update their Emergency Preparedness Plan prior to occupancy of the first project developed under the Transit Zoning Code (SD 84A and SD 84B), to address the potential for the accidental release of hazardous materials that may be used, stored, and/or transported in association with operation of project implementation. (Impact 4.5- 6) MM4.5-8 Project applicants shall submit evacuation plans on a project by project basis that shall be reviewed and approved by the City Police and Fire Departments. (Impact 4.5-6) Project Analysis and Conclusion The City determined that impacts related to people residing or working in the vicinity of a private airstrip/heliport and wildland areas would have no impact (DEIR Section 4.5.3: Effects Found to Have No Impact). Impacts related to transportation, storage and disposal of hazardous materials (Impact 4.5-1) and handling of hazardous materials near a school (Impact 4.5-3) were below the level of significance and did not require mitigation. Impacts related to reasonably upset of hazardous materials into the environment (Impact 4.5-2), hazardous materials sites (Impact 4.5-4), construction safety hazards for people or residing in the TZC area (Impact 4.5-5) and interference with an adopted emergency response playa (Impact 4.5-6) were less than significant with the implementation of mitigation measures. 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.
