Flood-prone work needs Fort Bend permit review

Flood risk in Fort Bend is not only about whether a house has flooded before. It also affects what work is allowed on the land.

A project inside a mapped floodplain or flood-prone area needs a county development permit before work starts. The rules treat development broadly. Construction, fill, grading, and some repairs to existing structures can all count.

Near a creek, bayou, the Brazos, or any mapped flood zone, check the county floodplain map and permit page before changing the site. The permit answer helps prevent violations and can protect neighbors from worse flooding.
