California Code, Government Code - GOV § 65456

(a) The legislative body, after adopting a specific plan, may impose a specific plan fee upon persons seeking governmental approvals which are required to be consistent with the specific plan.  The fees shall be established so that, in the aggregate, they defray but as estimated do not exceed, the cost of preparation, adoption, and administration of the specific plan, including costs incurred pursuant to Division 13 (commencing with Section 21000) of the Public Resources Code.  As nearly as can be estimated, the fee charged shall be a prorated amount in accordance with the applicant's relative benefit derived from the specific plan.  It is the intent of the Legislature in providing for such fees to charge persons who benefit from specific plans for the costs of developing those specific plans which result in savings to them by reducing the cost of documenting environmental consequences and advocating changed land uses which may be authorized pursuant to the specific plan.

(b) Notwithstanding Section 66016, a city or county may require a person who requests adoption, amendment, or repeal of a specific plan to deposit with the planning agency an amount equal to the estimated cost of preparing the plan, amendment, or repeal prior to its preparation by the planning agency.

(c) Copies of the documents adopting or amending the specific plan, including the diagrams and text, shall be made available to local agencies, and shall be made available to the general public as follows:

(d) A city or county may charge a fee for a copy of a specific plan or amendments to a specific plan in an amount that is reasonably related to the cost of providing that document.
