Summary

No groundwater proof, no plat. Starting January 1, 2028.

The bill requires that a groundwater availability statement attached to a subdivision plat application follow rules set by the Texas Commission on Environmental Quality. It also orders cities and county commissioners courts to reject plat applications that fail to meet those groundwater requirements, and it lets counties in priority groundwater management areas adopt water availability rules notwithstanding a separate county platting provision. Developers relying on groundwater under their land would face a firmer certification standard starting January 1, 2028, with the commission required to write its rules by that same date.
