It shall be the duty of the charter commission to draft a proposed charter for the government of the county and to submit the same to the electors of the county for their approval or disapproval in the manner hereinafter provided. Within 30 days following its organization, and at any time thereafter that the commission deems necessary, the commission shall hold one or more public hearings for the purpose of receiving information and materials which will aid in the drafting of such charter. Within six months after organization, the commission shall submit a preliminary report to the board of county commissioners of the county, which shall include the text of the proposed charter. Sufficient copies of the report shall be made available for distribution to members of the public. The charter commission shall hold at least one public hearing to obtain citizen views concerning the preliminary report. Within 12 months following its organization, the commission shall submit its final report to the board of county commissioners. The final report shall include the full text and an explanation of the proposed charter, any comments deemed desirable by the commission, a written opinion by an attorney admitted to practice law in the state of Kansas and retained by the commission for such purpose that the proposed charter is not in conflict with the constitution and general laws of the state and any minority reports. Nothing in the proposed charter shall be construed to limit or restrict the power of the legislature to enact general laws which relate to counties. Such final report shall be available to members of the public upon request. Following the submission of its final report the commission shall continue in existence for a period of time necessary for the conclusion of its affairs.
