California Code, Penal Code - PEN § 13901

(a) For the purposes of coordinating local criminal justice activities and planning for the use of state and federal action funds made available through any grant programs, criminal justice and delinquency prevention planning districts shall be established.

(b) On January 1, 1976, all planning district boundaries shall remain as they were immediately prior to that date. Thereafter, the number and boundaries of those planning districts may be altered from time to time pursuant to this section; provided that no county shall be divided into two or more districts, nor shall two or more counties which do not comprise a contiguous area form a single district.

(c) Prior to taking any action to alter the boundaries of any planning district, the council shall adopt a resolution indicating its intention to take the action and, at least 90 days prior to the taking of the action, shall forward a copy of the resolution to all units of government directly affected by the proposed action.

(d) If any county or a majority of the cities directly affected by the proposed action objects thereto, and a copy of the resolution of each board of supervisors or city council stating its objection is delivered to the Director of Emergency Services within 30 days following the giving of the notice of the proposed action, the director shall conduct a public meeting within the boundaries of the district as they are proposed to be determined. Notice of the time and place of the meeting shall be given to the public and to all units of local government directly affected by the proposed action, and reasonable opportunity shall be given to members of the public and representatives of those units to present their views on the proposed action.
