Santa Ana Zoo Stormwater Capture and Diversion Project December 2, 2025 Page 5 Proiect Milestones Milestone Estimated Date Notes Administrative Startup January 2026 Contract execution, bonds, insurance Material Procurement January 2026 — April 2026 Lead times may affect schedule Estimated Notice to May 2026 Start of working days Proceed Estimated Project March 2027 Based on 220 working Completion days The above dates are estimates and may be adjusted based on the actual Notice to Proceed date, material availability, weather, and unforeseen field conditions. The contractor will be required to minimize impacts to Zoo operations via implementation of a phasing plan. The contractor for this project will also be required to coordinate with the contractor working on the Zoo HIVE Educational Building project. Although both projects will be under construction concurrently, they are located in different areas of the Zoo. Public Works Agency staff and Zoo staff will meet regularly with both contractors to ensure that work progresses as scheduled and that any operational impacts are minimized. The project will include repaving the Zoo's entire main parking lot, as well as installing new parking stalls in the overflow parking lot. Temporary impacts to Zoo parking are expected during the final paving and striping phase but will be mitigated by scheduling much of the work outside zoo operating hours. During this period, visitors may still use street parking and the overflow parking lot as well. ENVIRONMENTAL IMPACT Pursuant to the California Environmental Quality Act (CEQA), an Initial Study/Mitigated Negative Declaration (IS/MND) was prepared for the Project and has been attached to this report as Exhibit 8. The purpose of the IS/MND is to describe the proposed project and to provide an evaluation of potential environmental impacts associated with the project's construction and operation. Moreover, the IS/MND evaluates the potential environmental impacts of project implementation; includes significance determinations from the environmental analyses; identifies regulatory requirements to be incorporated into the project; and sets forth mitigation measures that will lessen or avoid potentially significant project impacts on the environment. The IS/MND determined that the proposed project would have no impact, or less than significant impacts with mitigation measures, in all topics outlined in the CEQA Environmental Checklist. The final Mitigation and Monitoring Program, which includes the applicable mitigation measures, is included as part of the documents provided in Exhibit 8.
