Relating to the regulation of stormwater management by certain counties.

SB 1669 defines which Texas counties must follow existing stormwater management regulations under the Local Government Code. It applies specifically to counties with populations of 2.8 million or more (like Harris County), those relying on underground aquifers for drinking water (over 1.3 million people), or counties containing the Edwards Aquifer or within the Hill Country Priority Groundwater Management Area (800,000+ population). The bill amends Section 573.001 to clarify these county categories, ensuring only designated areas fall under the stormwater management chapter. This is a procedural adjustment to regulatory scope, not a new policy. The bill is currently in committee and has not yet passed.
