To request Comal County’s floodplain determination before building, submit a Floodplain Development Permit Application to the County Engineer’s Office with the required drawing, ownership proof and $40 fee.
The county uses the submitted information to determine whether the proposed structures are within a special flood hazard area. The fee pays for the application; submitting it does not itself establish that construction may proceed.
From the source record
Once all information has been received, the County will make a determination whether the structures for substantial improvements are located within the special flood hazard area.Comal County Engineer’s Office ↗
For property owners in unincorporated Comal County, the county’s determination establishes whether the proposed development must meet its flood damage prevention requirements. The county says its building permit guidance applies to unincorporated areas and cautions that municipalities and other entities may impose additional requirements. If a property is inside a city, check that city’s rules for the proposed work as well.
Gather the application materials
The county’s floodplain page lists four items for the application. The drawing must be to scale and show property lines, existing structures and proposed structures, with the structures tied to the property lines. For ownership proof, the county gives a warranty deed or release of lien as examples of recorded documents.
