Flood Zone Area Mapping Revisions

This project will provide flood control improvements to the Las Vegas and Flamingo Washes to reduce the Federal Emergency Management Agency (FEMA) high risk flood zone area mapping. The proposed plans for the project improvements were approved by FEMA in February 2014 through a Conditional Letter of Map Revision (CLOMR). A CLOMR is FEMA’s comment on a proposed project that would, upon construction, revise the high risk flood zone area mapping for the community.  A CLOMR does not result in a flood map change until construction is completed and FEMA is notified.

Construction of the project started in November 2013 and is ongoing, for updates see our Construction page. Once construction of the proposed improvements is complete, the project will be certified that the project has been constructed in accordance with the CLOMR. A Letter of Map Revision (LOMR) will be prepared and submitted to FEMA. Approval of the LOMR by FEMA is generally issued within six (6) months of submitting the LOMR application. Upon approval of the LOMR, an official letter will be issued by FEMA to Clark County and the City of Las Vegas.

Clark County residents can find out if they are located in a flood zone through the Clark County Regional Flood Control website’s FloodZone Application. The FEMA Flood Map Service Center also has additional information to find your official flood map, access a range of other flood hazard products, and tools for a better understanding flood risk.

Flood Zone Information

Flood insurance is available for everyone, not just people living in flood zones. 20% of flood insurance claims come from people outside high risk flood zones and policies have a 30 day wait to take effect. Every home-owner should consider if flood insurance is a wise choice to protect their most valuable asset. For more information go to www.floodsmart.gov.
