The regulatory side of Storm Water Services' Flood Mitigation Program focuses heavily on construction. Development in a FEMA or Community Floodplain requires a Floodplain Development Permit from the floodplain administrator. Some remodeling or redeveloping of existing structures within the regulated floodplains also requires a Floodplain Development Permit.
Locate floodplain regulations for each jurisdiction within Mecklenburg County.
Wise land use in floodplains can save lives and property. The environmental benefits of restored floodplains include cleaner water in local streams and better habitat for wildlife. Green space along creeks can provide places for recreation or enjoying nature.
Floodplain Construction and Permits
A Floodplain Development Permit (FDP) has been required in Charlotte-Mecklenburg since 1994 for all development within the floodplain. To determine if your proposed development or lot is in or touching the floodplain, check the 3D Interactive Floodzone Mapping application.
The requirements are different in a regulated floodplain. Additional rules and permitting requirements apply to new construction, additions or renovations, even grading the soil in the floodplain. Floodplain regulations apply to both the FEMA Floodplain and Community Floodplain. For detailed, legal requirements please reference the Floodplain Regulations Technical Guidance Document and each jurisdiction's Floodplain Regulations.
There are two types of Floodplain Development Permit - General and Individual.
General Floodplain Development Permit
To comply with federal regulations, a General Floodplain Development Permit has been issued by the Mecklenburg County Floodplain Administrator covering certain activities in the floodplain. These generally include passive land use or activities that do not cause a technically-measurable increase on the Base Flood Elevation. The property owner does NOT need to apply for a permit and there is no fee for these permitted activities. Activities covered by the GFDP are described in detail in the Technical Guidance Document.
Individual Floodplain Development Permit
An Individual Floodplain Development Permit (IFDP) is required for all projects in the floodplain that do not meet the requirements covered by the General Floodplain Development Permit. In general, IFDPs are required for grading, filling, drilling, dredging, new construction, and renovations with a value of more than $10,000 if the structure does not already meet floodplain regulations.
The Individual Floodplain Development Permit Process is as follows.
Fill out the Individual Floodplain Development Permit Application.
Submit the applicable Application Check Sheet and indicating the type of development and location of the property within the floodplain.
Types of Development:
Location/Area of Development:
If your project involves unique circumstances not covered by the types of development listed, contact the Floodplain Administrator at 704-432-7246 or emailfloodinfo@MecklenburgCountyNC.gov
- Final Construction Plans or Sketches - For development anywhere in a floodplain submit one set of final construction plans or sketches showing all proposed work as indicated on the check sheet.
Flood Impact Assessment - Submit if indicated on check sheet.
Affidavits - For building renovations requiring an IFDP, also submit:
Owner Affidavit of Building Improvements - Upon review by the Floodplain Administrator, the property owner may need to record (via the Register of Deeds) one of the following documents in the property chain of title: Affidavit of Substantial Improvement/Community Exemption OR Affidavit of Non-Substantial Improvements
Initial Review - Submit the IFDP Application, applicable Check Sheet, other supporting forms and documentation, and contact information in person or through the mail to:
Mecklenburg County Flood Mitigation Program
2145 Suttle Avenue
Charlotte, NC 28208
Attn: Floodplain Permit Coordinator
Upon receipt of the IFDP, the applicant will receive either an Additional Information "ADD" Letter (if the application package is incomplete and cannot be reviewed), or an “Acknowledgement Letter” (if the application is complete and technical review will begin.)
Payment of Fees - A permit fee is assessed for IFDPs based on the costs of technical and compliance review. Payment of fees is due after the initial review of the application and prior to the technical review for compliance. A permit will not be issued until the fee payment is received by the County. Checks should be made payable to Mecklenburg County.
Technical Review and Permit Approval - The complete IFDP package will be reviewed by Storm Water Services' staff for compliance with applicable floodplain regulations. Due to the wide variation in the complexity of the submittal reviews, review times will vary. If the application is approved, the permit will be issued and sent to the applicant. The permit will include stated terms and conditions about when and where the Permit applies.
Upon approval or denial of your FDP application, you may receive a brief Customer Service Questionnaire to help us continue to improve our process. You may also submit the Questionnaire on-line.
After Construction is Complete - Construction of new buildings or placement of fill material in or near the floodplain can impact floodplain lines. Proper certification and/or as-built topographic mapping are required prior to final approval of projects in or near the floodplain.
All structures built on lots within the Community and/or FEMA Floodplain will automatically have a permit and Occupancy Hold placed through the building permit system. After construction is completed, a licensed Land Surveyor or Professional Engineer must fill out and submit to Mecklenburg County Flood Mitigation Program an Elevation Certificate form. The Floodplain Occupancy Hold will be removed and Certificate of Occupancy will only be issued upon submittal and approval of the FEMA Elevation Certificate.
For development in the Community Encroachment Area or FEMA Floodway Encroachment Area, a properly geo-referenced digital submittal of the topographic map is required.
For floodplain development outside of the above areas, a Professional Land Surveyor or Professional Engineer must complete this form: Certification of Development Outside the Community Encroachment Area.
Please note this information is a general summary. It does not take into consideration unique circumstances that may arise for individual properties during the permitting and building process. Specific legal requirements are outlined in local floodplain regulations.
After you finish building in a FEMA-regulated floodplain—but before anyone moves in or uses the building—you must get an Elevation Certificate (FEMA form 81-31).
The Elevation Certificate form must be completed by a Land Surveyor, licensed engineer, or architect registered in the State of North Carolina. An Elevation Certificate is necessary before you can receive a Certificate of Occupancy and before the power company can turn on electricity to the building. The Elevation Certificate is required by the National Flood Insurance Program (NFIP) to determine flood insurance rates for the structure. It also provides documentation that the community is enforcing building and floodplain ordinances.
Buying or selling floodplain property
There are more than 5,000 properties in Charlotte-Mecklenburg’s regulated floodplains, many of which have flood prone structures. It is legal to buy and sell floodplain property. However, the State of North Carolina requires sellers to inform buyers of flood risks or drainage problems. In North Carolina, the State Residential Property Disclosure Statement requires the seller to tell the prospective buyer if the property is a “flood hazard” or that the property is in a "Federally-designated floodplain.” Other questions on the Disclosure Statement require the seller to tell of any problems with standing water, dampness, or drainage.
Buyers should ask—and verify what the seller has told them—before committing to buy any property.
