Frequently Asked Questions

Do I need a permit to build in an El Paso flood zone?

Yes. Section 18.60.100 says no structure or land can be located, altered, or have its use changed inside a special flood hazard area without full compliance with Chapter 18.60, and § 18.60.090 requires a development permit to demonstrate that compliance before work begins.

What maps does El Paso use to define the flood hazard area?

FEMA's Flood Insurance Study for the City of El Paso, along with its Flood Insurance Rate Maps and Flood Boundary-Floodway Maps, adopted by reference under § 18.60.080 using the most current effective versions and any later revisions.

Can I build inside the regulatory floodway?

Only if you can prove it first. Section 18.60.230(A) prohibits fill, new construction, and substantial improvements in the floodway unless hydrologic and hydraulic analysis shows the project would not raise flood levels anywhere in the community during the base flood.
