Relating to the provision by a political subdivision of credits against impact fees to builders and developers for certain water conservation and reuse projects.

HB 13 requires Texas cities and counties (political subdivisions) to offer fee credits against water and wastewater impact fees to builders and developers who construct eligible water conservation or reuse projects. These credits apply to projects that reduce water use, decrease wastewater infrastructure needs, or lower stormwater demand per service unit, including those exceeding standard efficiency requirements. Political subdivisions must establish fair procedures to calculate, apply, and approve these credits. The bill takes effect 91 days after the legislative session ends.
