Frequently Asked Questions

Do I need a permit to build in a Sahuarita floodplain?

Yes. STC § 14.20.030(A) requires a floodplain use permit before any construction or development, including placing a manufactured home, begins on land covered by the town's floodplain title, which includes FEMA-mapped special flood hazard areas and local washes carrying at least 100 cubic feet per second of base flood discharge.

Can the town refuse to issue a floodplain use permit?

Yes. STC § 14.20.030(F) lets the floodplain administrator deny a permit for any development that does not conform to Title 14 or that poses a danger to life or property, after weighing factors such as flood velocity, debris hazards, sanitation risk and whether the project could be relocated on the same parcel.

What can I build in the floodway itself?

Very little. STC § 14.25.090 prohibits fill, new construction and substantial improvements in the floodway, allowing only limited open-space uses such as agriculture, parking, recreation and accessory residential yard uses that require no fill, excavation or storage of materials.

What happens if I develop in the floodplain without a permit?

STC § 14.15.080 makes unpermitted floodplain development unlawful and a Class 2 misdemeanor, with each day of the violation charged separately, and STC § 14.15.090 lets the town treat the development as a public nuisance it can abate or enjoin through court action.
