Midland County, TX Environmental Rules: Flood Zones (2026)

4, Flood Plain Determinations and Permits, requires the owner or developer to apply to the Midland County Floodplain Administrator for a floodplain determination before any construction activity on the site, or at the time of plat application, whichever is earlier; the Regulations specifically close a loophole by requiring the same application even from an owner who is not subdividing into two or more parts and so does not need a plat under the court order. Applications go on forms the Administrator supplies, and the county's website carries the Floodplain Permit Application.

1, Flood Damage Prevention Regulations, layers on a second compliance duty: the permit holder must also comply with the county's separate Revised Order Establishing Regulations for Flood Damage Prevention, a standalone order the Regulations cross-reference rather than restate. 2, Depth of Cover in a Special Flood Hazard Zone, sets a hard buried-utility standard that applies regardless of what is built above ground: buried facilities such as pipelines or utility lines in a playa or flood plain need three feet of cover, and that minimum jumps to six feet for buried facilities located in the floodway itself, reflecting the added scour risk where flood flows are meant to be conveyed.

Together these provisions route flood-zone development through the county's floodplain permit before construction, tie it to a separate flood-damage-prevention order, and set a specific depth standard for the oil-field pipelines and utility lines that cross playas and floodways throughout the county.
