FEMA Proposed Changes to Flood Hazard Maps 

The Federal Emergency Management Agency (FEMA) is in the process of updating the flood hazard maps for Newport Beach and the proposed changes place thousands of Newport Beach properties in designated flood hazard zones. The areas generally affected by FEMA’s proposed changes include properties in a large area of West Newport, on the Balboa Peninsula and Balboa Island, and in the Lido Peninsula Resort area. You can view the draft maps below. As proposed, local property owners that do not currently pay for flood insurance could find themselves paying up to $3,000 a year in new insurance costs.  

City of Newport Beach staff and a consultant thoroughly studied FEMA’s study and draft maps and believe that its methodology did not take into account certain, important local conditions such as sea wall height variations. The City intends to file an appeal with FEMA. While some local properties would still be in the flood hazard zone, the City’s proposal removes a number of properties from FEMA’s proposed maps. We encourage any concerned, affected property owner to join us in the appeal process by following these three short steps:

  1. Check the FEMA maps to see if your property is potentially affected;
  2. Complete the online appeal form; and
  3. Submit the form to the City of Newport Beach no later than  August 28, 2017. You can email it to Samir Ghosn or mail to City of Newport Beach, Building Division, 100 Civic Center Drive, Newport Beach, CA 92660.
