Get a permit before you build. Don’t build or grade within 10 feet of your property line so you don’t alter drainage between homes.
Flood insurance is available to residents of the Town of Flower Mound because the town participates in the National Flood Insurance Program (NFIP). As a requirement of participating in the NFIP the Town of Flower Mound is required to issue a permit for all development and enforce construction guidelines in the floodplain. If the Town fails to comply, the Town could be expelled from the NFIP and flood insurance would not be offered to residents. A floodplain development permit is required for work in the floodplain. This applies to all of the following, but not limited to:
Construction of new structures
Modifications or improvements to existing structures
Filling, grading, and land clearing
Drilling, and driving of Piles
Storage of material and/or equipment
Temporary stream crossing
Installation of septic systems
