Orange County anticipates applying for Round Two of the Rebuild Florida General Infrastructure Program (GIP) funding provided by the U.S. Department of Housing and Urban Development (HUD) to support long-term mitigation efforts by assisting the State of Florida and its local governments in minimizing or eliminating the risks and reducing losses from future disasters. This program is being administered by the Florida Department of Economic Opportunity (DEO) through the Community Development Block Grant - Mitigation (CDBG-MIT) Program.

National Flood
Insurance Program

The NFIP is a Federal program enabling property owners in participating communities to purchase insurance protection against losses from flooding.

The Community Rating System (CRS) is a program implemented by the Federal Emergency Management Agency (FEMA) to reward communities such as Orange County which undertake flood plain activities beyond the requirements of the National Flood Insurance Program (NFIP). Orange County began participation in the CRS in 1991 and currently has earned enough CRS points to be awarded a class 5 rating. This class 5 means that the citizens of Orange County who have flood insurance are receiving a 25% discount on their premium.

Lake Monitoring and
Lake Fact Sheets

The Orange County Stormwater Management Division has prepared important information for lakes within unincorporated Orange County. These Lake Fact Sheets includes information on:

  • Official lake names
  • Drainage basin
  • Base flood elevation
  • Normal high water elevation (NHWE)
  • Control structures

Lake Fact Sheets are available in combined PDF files alphabetically. Please click on a file below to find data on a specific lake.

Currently there are over 150 lakes being monitored. Historical stage level data for lakes can be obtained from the Water Atlas.

Rainfall Program

The Rainfall Program has been operated and maintained by the Stormwater Management Division since its inception in 1986. The network of gauges collects rainfall data at fourteen locations within nine of Orange County's twelve major drainage basins.

Stormwater Management Library

The Stormwater Management Division maintains a library containing various reports related to the hydrology and hydraulics of Orange County. Reports available include those for the master plans and capital improvement projects. The library is organized by the twelve major drainage basins within the County.

The library is located at the Stormwater Management office on the first floor of the Public Works facility. Available to download is a Library Book List. For further details please contact the Stormwater Management Division at
