Flood Map Update Project in Orlando

Important changes have occurred in the City of Orlando. A multi-year project to re-examine flood zones and develop detailed digital flood hazard maps has been completed. This effort was part of the national map modernization project to produce more reliable flood risk data and report it in a digital format. This new format enables communities to overlay and analyze flood data with street patterns, stormwater facilities and existing property improvements. In Orlando, surface water flow and drainage patterns have changed significantly in the 32 years since the first Flood Hazard Maps were produced for our area.

These changes are related to land development, erosion, land use, and other natural forces. The new Flood Hazard Maps are up-to-date with these changes and reflect current flood risks. New technology has provided much more detailed terrain modeling that translates to more accurate floodplain mapping. The City, Orange County, various other local communities and the Federal Emergency Management Agency (FEMA) have revised the Flood Hazard Maps, also known as Digital Flood Insurance Rate Maps (DFIRM).

The new maps became effective September 25, 2009, after a period of public review and the community officially adopted them. These updated digital flood maps allow property owners to make better financial decisions about protecting themselves and their property. The maps also help community officials, engineers, builders and others to make important determinations about where and how new structures and developments should be built. As a result, our community is a safer place to live.
