Unless the provisions or context otherwise require, the following definitions shall govern the construction of this chapter:

The county surveyor and the county assessor shall review the boundary description contained in those proposals which are not subject to the jurisdiction of the local agency formation commission pursuant to Chapter 6.6 (commencing with Section 54775) of Part 1 of Division 2 of Title 5 or Division 1 (commencing with Section 56000), Title 6 of this code. Whenever the county boundary commission is referred to in state law, the reference shall be deemed to be to the local agency formation commission when the reference is in connection with any proposal over which the local agency formation commission has jurisdiction.

Prior to circulation of a petition, if such circulation is required, or otherwise prior to filing with the board of supervisors or with the governing body of a district, the proposal shall be submitted to the county surveyor as provided in this chapter. Each such proposal shall be accompanied by a map showing the boundaries of the territory involved and by a specific detailed legal description of the boundaries of such territory.

If the territory involved in the proposal is located in two or more counties, a copy of the proposal shall be filed with the county surveyor of each such county. The county surveyor of each such county shall have jurisdiction over and shall report upon those portions of the boundaries and territory which shall be located within each such county.

Within 30 days after filing, the county surveyor shall review and report on boundaries set forth in the proposal. Failure to report on a proposal within said 30-day period shall be deemed approval of the boundaries as set forth therein.

Within 10 days after the filing of any proposal, the county surveyor shall give written notice as provided in Section 58855.5 by mailing notice of such filing:

Mailed notice of any proposal shall be sent first class and deposited, postage prepaid, in the United States mails and shall be deemed to have been given when so deposited. When notice is required to be given to:

Factors to be considered by the county surveyor in review of a proposal shall include:

If he deems it to be in the public interest, the county surveyor may hold a public hearing on the proposal. Notice of any such hearing shall be given to the same cities and districts as were given notice pursuant to Section 58855 and may be given to such other cities, districts, public agencies, or persons as the county surveyor may direct.

The county surveyor may make changes in the boundaries set forth in a proposal if:

If written notice was previously given pursuant to Section 58855, within five days after making any such change, the county surveyor shall give written notice thereof to any city or district, within three miles of the changed boundaries, which was not previously given notice.

The county surveyor shall deliver a copy of his report together with any recommendations made by the county assessor to the proponents and to the legislative body having jurisdiction to conduct appropriate proceedings.

If the proponents do not accept the county surveyor’s recommendations as contained in his report, they shall file a statement of reasons with the legislative body having jurisdiction to conduct the appropriate proceedings. The proponents shall also furnish a copy of such statement to the county surveyor. The proposal may be circulated or filed with the board of supervisors or the governing body of the district, if any, only after such a report has been furnished.

Before acting upon any proposal, the legislative body having jurisdiction shall consider the report of the county surveyor and give it such weight as in its judgment the public interest requires.
