City of Irvine
2020 Local Hazard Mitigation Plan
Plan Revision and Adoption
The City received public comments on the plan, however none of the comments required edits or modification to the plan content. Following public comment, the City submitted the plan to Cal OES and FEMA. The City then made additional revisions to incorporate comments from state and federal agencies, as appropriate, and submitted the final draft to City decision-makers. The Irvine City Council adopted the final LHMP on October 27, 2020. Appendix C contains a copy of the adoption resolution.
