Floodplain Development Permit Requirements

Any development in the floodplain requires a flood hazard area permit according to the Unified Land Development Code Ch. 406. If you need a flood zone determination, contact Alachua County Public Works at 352-337-6140 or the City of Gainesville Public Works at 352-334-5069.

If you need a FEMA elevation certification or suspect that illegal floodplain development is occurring call the Alachua County Building and Zoning Department at 352-374-5244 or the City of Gainesville Building Inspection Department at 352-334-5050.

Additionally, in accordance with NFIP standards, Alachua Co. Building Code requires if the cost of any reconstruction, rehabilitation, addition or other improvements to a building equals or exceeds 50% of the building’s market value, such work is considered a substantial improvement . The existing building is then required to meet the same standards as a new building. For residential structures, these requirements typically mean raising the living area of the building to the base flood elevation.

Substantial Improvement Requirements

Substantial improvement shall mean any repair from damage or destruction, reconstruction, improvement, or additions of a structure, the cost of which equals or exceeds 50% of the assessed tax value of the structure as is listed by the Alachua County Tax Assessors Office or by a certified appraisal. The assessed value of the structure shall be determined before the improvement is started, or if the structure has been damaged and is being restored, before the damage or destruction occurred.

Drainage System Maintenance

A community can lose a portion of its drainage system carrying or storage capacity due to dumping, debris, soil erosion and sedimentation, and overgrowth of vegetation. When this happens, flooding occurs more frequently and reaches higher elevations, subjecting properties otherwise protected to unnecessary risk of damage. Keep grass clippings and other debris out of stormwater storage and treatment capacity. Per county ordinance, it is illegal to dump trash and debris in drainage ways.

If you experience any localized drainage problems please notify the County Public Works Department at 352-374-5245 or 386-462-2147 or the City of Gainesville - Streets Division at 352-334-2161 so that the problem can be corrected.

Community Rating System-Alachua County is a Class 6 Community

On August 14^th, 2012, the Alachua County Commission was presented a Plaque from FEMA for improvement to a Class 6 from Class 7 Rating (on a scale from 1 to 10; 10 being the lowest, 1 being the highest) of the Community Rating System (CRS). The CRS is a voluntary incentive program of the National Flood Insurance Policies (NFIP) and provides for discounted flood insurance premiums to property owners in participating communities. The citizens of Alachua County would benefit with a 20% discount as opposed to 15% (an additional 5%) on their Flood Insurance premiums which amounts to an additional cumulative savings of $28,403 based on 1565 active policies.

The CRS rating is effective May 1^st 2012 and good for 5 years.

Alachua County has been a participating community in the NFIP since 1984 and in the CRS since 1995. The Community Rating System effort is a result of collaboration between the various Alachua County Departments; Fire Rescue, Growth Management, Environmental Protection and Public Works.

The three goals of the CRS are:

1. Reduce flood damage to insurable property.
2. Strengthen and support the insurance aspects of the NFIP and
3. Encourage a comprehensive approach to Floodplain Management.

This reflects the County’s commitment to protecting lives and property through mitigation and wise planning practices.
