Relating to the authority of a county to establish drainage utilities, impose drainage fees, and regulate land use for the purpose of flood management.

SB 45 allows Texas counties to establish drainage utilities for unincorporated areas, impose drainage fees on new development to fund flood control infrastructure, and adopt land use regulations for flood management. Key provisions include setting impervious cover limits (without banning all development in floodplains), requiring setback standards, and permitting landscaping rules. Municipal ordinances take precedence over county regulations for the same conduct, and drainage utility service areas cannot include municipal extraterritorial jurisdictions. This bill directly affects counties managing flood risks, land developers in unincorporated areas, and residents who may face new drainage fees or land use requirements.
