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

HB 190 allows Texas counties to establish drainage utilities for unincorporated areas and adopt land use regulations - such as setback requirements, lot size standards, and landscaping rules - to manage flood risks without banning all development in floodplains. It also authorizes counties with populations of 3.3 million or more (or bordering such counties) to impose impact fees on new developments to fund stormwater and flood control improvements. County land use rules must be directly tied to flood management, and municipal ordinances override conflicting county regulations. The bill provides counties with new tools for flood mitigation but does not require them to implement these measures.
