Floodplain Management

Floodplain management assists customers in meeting the requirements of the Santa Rosa County Land Development Code and the National Flood Insurance Program. This office is the archive for all the flood information for the county, and the other local jurisdictions, including flood insurance rate maps, elevation certificates, letters of map amendment, historical flooding, coastal barrier resources areas, and flood insurance studies. This office is also responsible for the Community Rating System or CRS information. CRS is a voluntary program which based on activities performed determines a discount from 5 percent to 40 percent on flood insurance rates. This office assists the special projects and grants department with Mitigation of flood prone structures. The following information can be obtained from this office.


Our online flood insurance rate maps are available at:  just enter your address, parcel number or the property owners name and in the layers click on “Flood Layers”.  If we can help you with a flood determination, assistance with reading a flood map either on line or in person or any of the items listed below, please feel free to contact us at 850-981-7029.

Dumping is a violation of Santa Rosa County Ordinance 06-26. Do not dump or throw anything into the ditches, streams, creeks, or rivers. Even grass clippings and branches can accumulate and plug channels, creeks and streams. A blocked channel cannot carry water and when it rains the water has to go somewhere. Every piece of trash contributes to flooding.   If your property is next to a ditch or stream, please do your part and keep the banks clear of brush and debris. Santa Rosa County has a maintenance program which can help remove major blockages such as debris in ditches. Please call 626-0191 or fill out a Work Order online at


Flood Insurance


  • Did you know that homeowners insurance does not cover flood damages?  Only flood insurance covers flood damages.  As a member the National Flood Insurance Program, flood insurance is available to all citizens of Santa Rosa County.
  • Did you know that there is a 30 day waiting period before insurance coverage will be effective?  So do not delay in obtaining flood insurance coverage. 
  • Did you know that 30% (approximately) of all flood insurance claims arise from Zone X (area of minimal flooding)? Just because you are not in a high hazard zone, does not mean that you will never flood. 
  • Take precautions with your property, purchase flood insurance.  Talk to your insurance agent today or visit the “FloodSmart” web page listed in the links below.


Protection Measures


If you have questions about Flood Protection and what can be done at a specific location to possibly mitigate future flood damages we can help with those questions. Please contact our Floodplain Manager for further information or read the “Property Protection” flyer in the links below. If a site visit is needed, we can set that up as well.

Turn Around Don’t Drown:  Remember that 12” of water can float a car, don’t drive thru a flooded street or go around barricades.

Prepare for flooding by doing the following:

  • Know how to shut off the electricity and gas to your house when a flood comes.
  • Make a list of emergency numbers and identify a safe place to go.
  • Make a household inventory
  • Put insurance policies, valuable papers, medicine, etc in a safe place
  • Collect and put cleaning supplies, camera, waterproof boots, etc in a handy place.

Consider some flood protection measures.

  • Mark your fuse box to show the circuits in the floodable areas.
  • Consider elevating your structure above flood levels
  • Check your building for water entry points, such as dryer vents.  These can be protected by low walls or temporary shields.
  • Install a floor drain plug, standpipe, overhead sewer backup valve to prevent sewer backup flooding.

Develop a disaster response plan. See the Red Cross’ website at for information

  • Get a copy of “Repairing your flooded home”.  This can be found at the Red Cross’ website listed above.

Talk to the Grants Department for possible grants for mitigation

  • Please remember that the more documentation you have regarding past flooding, the better we can assist you with possible grant opportunities.  All grants are competitive and require a benefit cost analysis. 
  • For more information contact the Grants Department at 850-981-1848


Building Responsibly

  • If you see illegal floodplain development you can report this by calling the compliance department 850-981-7000 or on line at:


What is Substantial Improvement or Substantial Damage and what are the rules? Substantial Improvement  as defined in 44 Code of Federal Regulations 59.1 means: “any reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure before the “start of construction” of the improvement. This term includes Substantial Damage, regardless of the value of or actual cost of repair work performed.  The term does not, however, include either (1) any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions or (2) any alteration of a “historic structure”, provided that the alteration will not preclude the structure’s continued designation as a “historic structure”.”
