Section 414.6 - Zoning commission - powers and duties1. In order to avail itself of the powers conferred by this chapter, the council shall appoint a commission, to be known as the zoning commission, to recommend the boundaries of the various original districts and appropriate regulations and restrictions to be enforced therein. Where a city plan commission already exists, it may be appointed as the zoning commission. Such commission shall, with due diligence, prepare a preliminary report and hold public hearings thereon before submitting its final report; and such council shall not hold its public hearings or take action until it has received the final report of such commission. After the adoption of such regulations, restrictions, and boundaries of districts, the zoning commission may, from time to time, recommend to the council amendments, supplements, changes, or modifications.2. The zoning commission may recommend to the council for adoption a comprehensive plan pursuant to section 414.3, or amendments thereto.C24, 27, 31, 35, 39, §6457; C46, 50, 54, 58, 62, 66, 71, 73, 75, 77, 79, 81, § 414.6 2010 Acts, ch 1184, §24Referred to in §329.9, 414.3, 657.9
