Flood Plain Management

Unincorporated Lake County and the
National Flood Insurance Program, Community Rating System

Floodplan Management Regulations
The basis of lake County's floodplain management regulations is the flood hazard data provided to the community by FEMA. FEMA identifies flood hazards nationwide and publishes and updates flood hazard data in support of the NFIP (National Flood Insurance Program). Flood hazard data is provided to Lake County in the form of a Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS).

Flood Hazard Identification
Identifying flood hazards creates an awareness of the hazard, especially for those who live and work in flood-prone areas. Maps provide states and communities with the information needed for permitting land use planning and to reduce flood risk to floodplain development and implement other health and safety requirements through codes and regulations.

Changes to the flood hazard data
FEMA generally updates the Flood Insurance Rate Maps (FIRMs) every ten years. The latest update of Lake County’s FIRM was 2012 and are available upon request. Each time FEMA provides Lake County with new flood hazard data, Lake County must adopt the new FIRM and incorporate the new data and any additional requirements that result from changes, such as the designation of a floodway for the first time. Lake County’s floodplain management regulations must also meet any additional Community Rating System (CRS) requirements and be adopted through a process that complies with procedural requirements established by the State of Florida for the adoption of ordinances or regulations.

FEMA's National Flood Insurance Program
Lake County participates in the National Flood Insurance Program (NFIP). The NFIP makes federally backed flood insurance available for all buildings, whether they are in a floodplain or not. As a participating community in the NFIP, Lake County is responsible for making sure that its floodplain management regulations meet or exceed the minimum requirements of the NFIP. By law, the Department of Homeland Security's Federal Emergency Management Agency (FEMA) cannot offer flood insurance in communities that do not have regulations that meet or exceed these minimum requirements. These regulations can be found in Title 44 of the Code of Federal Regulations (44 CFR) Section 60.3.

Written Floodplain Determinations
A written flood determination may be obtained for any parcel that is within the unincorporated areas of Lake County for a fee of $15 (cash or check). A Floodplain Determination Form must be completed for all written determination request.

Lot Grading
Addressing grading and drainage is an important part of any project. Lake County has Land Development Regulations for lot grading. Depending upon the size and scope of your project, a scaled plot plan showing proposed grading of the lot, fill, water bodies, wetlands and other features may be required along with a lot grading Inspection. Lot grading plans are reviewed to ensure positive drainage with no adverse Impact to adjacent properties, surface water bodies, flood zones and wetlands. If you are unsure if Lot Grading review will be required for your project, click on the pamphlet for a printable checklist.
