AZ HB2220

Amends Arizona law to allow improvement districts to continue operating in areas no longer designated as "designated areas" if the district was formed before the effective date of this amendment and meets specific conditions.

Requires that the area must have been in a designated area for at least five or more years at the time of district formation.

Restricts property ownership concentration, limiting any single owner to no more than 10 percent of the property frontage in the improvement district.

Allows district continuation only if no more than one-third of property owners by frontage file written objections to the improvement district with the municipality.

Requires the municipality to comply with existing statutory procedures for improvement district formation and operation.
