Iowa Code Title IX. Local Government [Chs. 331-420] § 386.5. Dissolution

1. A district may be dissolved and terminated by action of the council rescinding the ordinance creating the district, and any subsequent ordinances amending the district, by an affirmative vote of three-fourths of all members of the council, or in cities having but three members of the council, the affirmative vote of two members. However, if a remonstrance has been filed with the clerk signed by at least twenty-five percent of all owners of property within the district representing ownership of property with an assessed value of twenty-five percent or more of the assessed value of all the property in the district, the rescission of the ordinance creating the district, and any subsequent ordinances amending the district, requires a unanimous vote of the council.

2. At any time prior to action of the council rescinding the ordinance creating the district, and any subsequent ordinances amending the district, the entire matter of dissolving a district shall be withdrawn from council consideration if a petition is filed with its clerk containing the signatures of at least forty percent of all owners of property within the district or signatures which together represent ownership of property with an assessed value of forty percent or more of the assessed value of all property within the district.
