The Flood Insurance Rate Map Collection contains a series of maps highlighting areas of potential flood risk throughout Los
Angeles County. The maps were produced by the Federal Emergency Management Agency (FEMA) as part of the National Flood Insurance
Program series. Maps from the collection include both incorporated and unincorporated areas of Los Angeles County, emphasizing
areas of the County that contain creeks, channels, reservoirs, and other permanent or seasonal waterways. The bulk of the
collection dates from the 1980s to the 1990s, with some maps from the 1970s and 2000s. Flood insurance maps also include municipal
details like roads and highways.
