Flood Map Modernization Process
Flood hazard maps, also known as Flood Insurance Rate Maps (FIRMs), are important tools in the effort to protect lives and properties in Hesperia. They indicate the risk for flooding throughout the community.

However, the current maps are out of date. Some formerly rural areas were never mapped in detail, and other areas haven’t been re-mapped in more than 10 years.

Over time, water flow and drainage patterns have changed dramatically due to surface erosion, land use and natural forces. The likelihood of inland, riverine and coastal flooding in certain areas has changed along with these factors. The floods of 2006 are a recent example of these changes.

New digital mapping techniques will provide more detailed, reliable and current data on San Bernardino County flood hazards. The result: a better picture of the areas most likely to be impacted by flooding and a better foundation from which to make key decisions.
