Description: This dataset represents the boundaries of the Federal Emergency Management Agency's (FEMA) Flood Insurance Rate Maps (FIRM). The area in Clark County has been subdivided into panel designations for the publication of FIRMs. The FIRMs are a product of a flood insurance restudy of the Las Vegas valley which completed in September, 2002. This layer has been updated to reflect the physical map revisions for the Gowan/US 95, Moapa Valley, and Las Vegas Wash areas which became effective November 16, 2011
