FEMA Re-Mapping Flood Hazard Zones on Southern California Coast

The Federal Emergency Management Agency (FEMA) is currently evaluating sections of Malibu along the coastline to be re-mapped within the new preliminary flood hazard zones. These maps represent an important step toward increasing public safety by better equipping residents and property owners to make decisions about protecting themselves and their properties.

With these maps, residents and businesses will have up-to-date, reliable, Internet-accessible information about their flood risk on a property-by-property basis. Community planners, engineers, builders, and others will be better able to make important determinations about where and how new structures and developments are built.

The maps are considered preliminary until they are adopted in early 2018. A Public Appeal Period will be offered in the Summer/Fall of 2017. (FEMA has yet to set the appeal period.) During this appeal period, residents may submit appeals and protests if they disagree with the maps and believe an error has been made. Property owners who want to appeal are required to submit the scientific or technical data intended to negate or contradict FEMA’s findings to Malibu’s Floodplain Administrator.

At the end of the appeal period, the City will evaluate all appeals and submit its findings to FEMA. Once FEMA reviews all appeals and protests, and incorporates any needed map changes, a Letter of Final Determination will be issued. Six months later, the maps will be adopted and become effective, as will any new flood insurance requirements. However, starting immediately, the City intends to use these flood hazard maps to help determine requirements for construction and development.

The City will conduct a series of community meetings to inform the public about these proposed map revisions.
