(1) Notice and hearing. No airport zoning regulations shall be adopted, amended, or changed under this chapter except by action of the legislative body of the political subdivision in question, or the joint board provided for in RCW
14.12.030(2), after a public hearing in relation thereto, at which parties in interest and citizens shall have an opportunity to be heard. At least fifteen days' notice of the hearing shall be published in an official paper, or a paper of general circulation, in the political subdivision or subdivisions in which is located the airport hazard area to be zoned.
(2) Airport zoning commission. Prior to the initial zoning of any airport hazard area under this chapter, the political subdivision or joint airport zoning board which is to adopt the regulations shall appoint a commission, to be known as the airport zoning commission, to recommend the boundaries of the various zones to be established and the regulations to be adopted therefor. Such commission shall make a preliminary report and hold public hearings thereon before submitting its final report, and the legislative body of the political subdivision or the joint airport zoning board shall not hold its public hearings or take other action until it has received the final report of such commission. Where a city plan commission or comprehensive zoning commission already exists, it may be appointed as the airport zoning commission.
