Cal. FAC § 8764.6

(a) In determining the boundaries of the district, the board of supervisors shall exclude from the district any olive, stone, and pome fruit acreage that it finds will not be benefited by the proposed project, and it may include in the district any noncontiguous lands that it finds will be benefited if it also finds it will be in the interest of the district to include these lands. The inclusion may be upon application of the owner or, without the owner’s application, upon giving the owner notice of the proposed inclusion and an opportunity for a hearing on it.

(b) Notice of inclusion shall be mailed, postage prepaid, by the clerk of the board of supervisors, to the address of the owner of the land as shown by the last equalized county assessment roll, and to any person that has filed with the clerk that person’s name and address and description of land in which he or she has either a legal or equitable interest. The notice shall describe the land proposed to be included, and shall state the time and place at which objections to the inclusion will be heard.
