adequate water supply; statewide requirements

HB 2481 requires municipalities in Arizona to verify adequate water supply before approving new housing subdivisions. It mandates that developers submit a "certificate of assured water supply" from the state water resources director (for areas with water scarcity) or a written commitment from a water provider with adequate supply. This applies to all new subdivisions within designated water management areas and, if the state issues a water notice, to subdivisions outside those areas as well. The requirement must be included on the subdivision plan before final approval, directly affecting developers and local planning departments.
