HB 4064 amends Arizona law to streamline the formation of municipal improvement districts for specific infrastructure projects, including pedestrian malls, parking facilities, retention basins, and parkways. It allows a governing body to immediately approve such districts if a petition signed by all real property owners (excluding mortgagees) is submitted, skipping standard public notice requirements. This directly affects property owners within proposed districts by simplifying the process for funding and maintaining these shared public improvements. The key change reduces procedural steps when unanimous owner support is demonstrated, shifting funding to either ad valorem taxes or proportional property assessments. The bill focuses on administrative efficiency rather than altering funding mechanisms.
