Floodplain regulations are intended to reduce risks to people and property in areas in the community that are prone to flooding. The City of Leon Valley regulates development based on FEMA Flood Insurance Rate Maps of the 100-year floodplain. The regulated floodplain currently covers approximately 14.4 percent (319 acres) of Leon Valley and 277 living spaces.

Floodplain Development Permits
Property owners with buildings located in the 100-year floodplain are required to obtain a Floodplain Development Permit before expanding a building or constructing improvements.
Complete the Floodplain Development Permit Application and bring it to the Planning & Zoning Department at City Hall at 6400 El Verde.
Floodplain Information Requests
Use the Map of Floodplains (Interactive) to see if your property is located in a floodplain.
To have city staff look up your floodplain information, fill out the Floodplain Information Request form and either fax it to 210-509-8288 or drop it off in-person at the Community Development Department City Hall at 6400 El Verde.
Use the FEMA Map Service Center to access a Public Flood Map or a Flood Insurance Rate Map.
Adding Your Property to the Regulated Floodplain
There are many areas in Leon Valley that are currently outside of the highest-risk floodplains, but are still at risk for flooding. In these areas, property owners may choose to meet or exceed floodplain regulations and/or obtain discounted flood insurance, depending on their tolerance for risk.
Removing Your Property from the Regulated Floodplain
If your structure is elevated or if your property was incorrectly mapped in the regulated floodplain, you may request that it be removed from the floodplain. Contact a licensed land surveyor to determine if your property qualifies for a Letter of Map Amendment to potentially remove your property from the floodplain. Although Leon Valley’s floodplain mitigation and regulation is aligned with a 100-year flood, that doesn’t mean flooding can’t happen outside of the floodplain at any time.
Built Out of the Floodplain, but Now Mapped In? The NFIP’s “Grandfather” Clause Might Be of Assistance
Buildings newly mapped into a high-risk flood area initially may be eligible for a lower cost PRP rate in the year following a map change. Talk to your insurance agent and see if your home qualifies for a reduced flood insurance rate. You may be asked to contact the City for information regarding the building permit for your home and the FIRM map that was in effect at the time it was built. If so, please contact the Planning & Zoning Department at (210) 684-1391 x 228. The link below gives information for your insurance agent on “Grandfathering” in these cases.
