Relating to the adoption of a water conservation program by certain counties.
HB 2347 requires certain Texas counties with priority groundwater management areas to adopt water conservation programs for new developments. The bill applies to unincorporated areas and land outside city limits (extraterritorial jurisdiction) where new construction begins after August 31, 2025. It sets conservation standards for development projects but explicitly excludes agricultural operations as defined in the Agriculture Code. Municipal ordinances take precedence over county rules for the same activities. The law takes effect September 1, 2025.

MODERATE
The bill was reformatted and its substantive content was significantly altered. The most important change is that water conservation standards now only apply to landscaping water in residential developments, rather than all developments. Additionally, the conflict resolution rules were expanded to include non-municipal governmental entities, and a new expiration date of September 1, 2031 was added.
Scope change
The bill's scope was narrowed to apply only to landscaping water in residential developments, and the eligibility criteria for counties were modified to require a population greater than 230,000, location within the Hill Country Priority Groundwater Management Area, and adjacency to a county with over one million population.
REQUIREMENT
Water conservation standards now apply only to landscaping water in residential developments, removing the broader application to all development types.
TIMELINE
A new expiration date of September 1, 2031 was added for the subchapter and any adopted programs.
ENFORCEMENT
Conflict resolution rules were expanded to include non-municipal governmental entities, specifying that more stringent regulations prevail for non-municipal entities.
ELIGIBILITY
New eligibility criteria require counties to have a population greater than 230,000, be located within the Hill Country Priority Groundwater Management Area, and be adjacent to a county with over one million population.
