The Engineering Division is charged with the maintenance and enforcement of the City's floodplain and floodway ordinances as mandated by the National Flood Insurance Program.  The City Engineer operates in the capacity of the Certified Floodplain Administrator (CFM).

If your property is located within the City Limits of Conroe, you may request a Floodplain Letter from the City to aide in identifying if your parcel is affected by the 100-year Floodplain.

The following was adapted from the Federal Emergency Management Agency website.

The Federal Emergency Management Agency (FEMA) publishes maps, called Flood Insurance Rate Maps (FIRMs). The purpose of a FIRM is to show the areas in our community that have a 1% or greater chance of flooding in any given year, known as Special Flood Hazard Areas (SFHAs). FIRMs are the result of engineering studies that are performed by engineering companies, federal agencies, or the community and are reviewed and approved by FEMA.

Although FEMA uses the most accurate flood hazard information available, limitations of scale or accuracy of topographic information used to prepare the FIRM may cause small areas that are at or above the flood elevation to be inadvertently shown within the SFHA boundaries. Also, the placement of fill may elevate small areas within the SFHA boundaries to an elevation at or above the flood elevation. When this happens, structures or parcels of land may be inadvertently included in the SFHA on the FIRM.

If you believe your home or business is not located in a SFHA, as shown on the Flood Insurance Rate Maps (FIRM) of Conroe and would like FEMA to make an official determination regarding the location of your property relative to the SFHA, you may request a Letter of Map Amendment (LOMA) or a Letter of Map Revision Based on Fill (LOMR-F).  LOMAs and LOMR-Fs are documents issued by FEMA that officially remove a property and/or structure from the SFHA. To obtain a LOMA or LOMR-F, the applicant must submit mapping and survey data for the property. In most cases, the applicant will need to hire a land surveyor to prepare an Elevation Certificate for the property.

The issuance of a LOMA or LOMR-F eliminates the federal flood insurance purchase requirement as a condition of federal or federally backed financing.  However, the mortgage lender retains the prerogative to require flood insurance as a condition of providing financing, regardless of the location of the structure.
