*** Revised Flood Insurance Rate Map (FIRM) and Flood Insurance Study (FIS) Report, for the unincorporated areas of Waller County, Texas, Community No. 480640 ***

The Department of Homeland Security’s Federal Emergency Management Agency (FEMA) is pleased to present your community with revised FIRMS and FIS Report to be effective May 16, 2019, for Waller County, Texas and incorporated areas. This revised version of the FIRM panels and FIS Report incorporates updated flood hazard information for the Lower Brazos Watershed Study. We have revised only those FIRM panels with updated flood hazard information.

See the Waller County Road and Bridge GIS Website, click Revised Floodplain - Eff. 5.16.19.

Floodplain Development PermitALL new construction (including earthwork) in the unincorporated areas of the County must obtain a permit or permit exemption prior to beginning any construction activities.  A development permit application must be completed in order to get a floodplain determination from the County Engineer’s Office and further information on permit requirements if development is in the 1% annual chance (fka, 100-yr) floodplain.  FEMA Flood Insurance Rate Maps are also located on our website.  Failure to abide by the Flood Damage Prevention Ordinance regulations could result in both civil and criminal sanctions.

Development (per FEMA) means any man-made change to improved or unimproved real estate including, but not limited to, buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials.

Driveway/Culvert Permit – A driveway (with or without a culvert) is required in order to get legal access onto a County maintained road from private property.  The driveway must be constructed in conformance to County standards.  


For mutli-family residential, commercial and other public developments a full set of civil site plans (i.e. site grading, drainage, erosion control, fire lanes, utilities, SWPPP, detention, etc.) must be submitted prior to commencement of any construction activities.  Our Drainage Criteria Manual is located in Appendix E of our Subdivision and Development Regulations.  If the property is within the jurisdiction of the Brookshire-Katy Drainage District, construction plan approval must also be obtained through their office.


Failure to abide by the subdivision rules and regulations could result in both civil and criminal sanctions.


If you divide your property into two or more parcels to convey to others, such “subdividing” is regulated by state law in Texas Local Government Code Chapter 232.

A property owner who intends to use the land for any type of rental community, including a manufactured home rental community or RV park, must have an infrastructure development plan prepared that complies with the minimum infrastructure standards established in Appendices C & D of our Subdivision and Development Regulations.
