Moving Dirt Outside Town May Need a Floodplain Permit First
Development in the unincorporated floodplain needs a permit before work starts. That means the permit comes before fill, grading, paving, excavation, drilling, storage yards, or a manufactured home placement.
FEMA's definition of development is wide. It is not limited to building a house. Storing equipment or materials on the ground can count too.
The floodplain office is at 219 W. 5th Street, Building 7, in Sinton. Susan Boutwell is listed as floodplain and permits manager, and the office phone is (361) 587-3567.
