FEMA Agrees to Flood Maps Changes
The City’s Community Development Department has been working with the Federal Emergency Management Agency (FEMA) for the past two years to revise its proposed flood hazard maps. The City is happy to announce that FEMA has agreed to remove over 2,700 properties from flood zones, which is estimated to save residents up to $10 million a year in insurance premiums.
Below are the side-by-side comparisons of the originally FEMA proposed maps for Newport Beach and the results of the City's efforts to have FEMA further revise the maps. There are also many resources listed should you want additional information on this issue.
If you have questions, please contact the Community Development Department by calling 949-644-3200.
