Chapters 20.02 - 20.60 may be amended to establish detailed zoning districts, to change district boundaries or to change any other provisions thereof whenever the public necessity and convenience and the general welfare require such amendment by following the procedure set forth in this chapter.

(Ord. 67-10 § 5.0300, 1967)

An amendment may be initiated by:

1. The petition of one or more property owners, or their authorized agents, affected by the proposed amendments which petition shall be filed with the planning commission.
2. Board of supervisors.
3. Planning commission.

(Ord. 67-10 § 5.0301, 1967)

An application for an amendment pursuant to Section 20.52.20A., shall be accompanied by a filing fee as prescribed in the current fee schedule resolution of the board of supervisors and shall also be accompanied by the following data necessary to demonstrate that the proposed amendment is in general conformance with the general plan and that the public necessity, convenience, and general welfare, require the adoption of the proposed amendment:

1. An accurate legal description and map showing:
   1. Properties within the proposed or amended zoning district,
   2. Boundary of the district,
   3. Roads, rights-of-way or other data deemed pertinent by the planning commission;
      
2. This map shall be drawn on a sheet or sheets eighteen inches by twenty-six inches with a one inch border, and shall be drawn on tracing paper or similar material, to a scale of one inch equal four hundred feet.

(Ord. 2009-003 § 5 (part), 2009: Ord. 67-10 § 5.0302, 1967)

1. The planning commission shall hold one or more public hearings on any proposed amendment, at least ten days apart, and shall give notice thereof by at least one publication in a newspaper of general circulation within the county at least ten days prior to the first of such hearings.
2. In case the proposed amendment consists of a change of the boundaries of any district so as to reclassify property from any other district, the planning commission shall give additional notice of the time and place of such hearings and of the purpose thereof by posting public notices thereof not less than ten days prior to the date of the first of such hearings along the streets or roads upon which the property proposed to be reclassified abuts and in the vicinity thereof. Any failure to post public notices as aforesaid shall not invalidate any proceedings for amendment of Chapters 20.02 - 20.60.
3. In case the proposed amendment consists of a change of zoning, the planning commission shall give further additional notice of the time and place of such hearings and of the purpose thereof. This notice shall be mailed first class, postage prepaid, at least ten days prior to the first hearing. The notice shall be addressed to each property owner in the area involved at his address as it appears on the latest current secured assessment roll of the county of Del Norte. Proof of mailing shall be by declaration under penalty of perjury filed with the commission. The failure of the property owner to receive the notice shall in no way invalidate any proceedings under this chapter.

(Ord. 69-15 § 1, 1969: Ord. 67-10 5.0303, 1967)

Following the aforesaid hearings, the planning commission shall submit a written report of its findings and a summary of hearings, together with its written recommendation with respect to the proposed amendment to the board of supervisors. Upon the consent of the planning commission, any petition for an amendment may be withdrawn upon the written application of a majority of all the persons who signed such petition. Where an amendment has been referred by the board of supervisors to the planning commission for a report, such report shall be made to the board of supervisors within forty days. Failure to do so shall be deemed an approval of the proposed regulation or amendment by the planning commission.

(Ord. 67-10 § 5.0304, 1967)

Upon receipt of the recommendations from the planning commission, the board of supervisors shall set the matter for public hearing and shall give notice thereof by one publication in a newspaper of general circulation within the county at least ten days prior to such hearing. The board may approve, modify or disapprove any recommendation of the planning commission. Any modification of the proposed ordinance or amendment shall be referred back to the planning commission for a report and recommendation. Within ninety days from the date of receipt, the board of supervisors may adopt the proposed amendment or any part thereof. The board of supervisors by resolution may abandon any proceedings for an amendment initiated by its own action, provided that such abandonment may be made only when such proceedings are before such body provided that any hearing of which public notice has been given shall be held.

(Ord. 67-10 § 5.0305, 1967)
