65584.03.  (a) At least 28 months prior to the scheduled housing element update required by Section 65588, at least two or more cities and a county, or counties, may form a subregional entity for the purpose of allocation of the subregion’s existing and projected need for housing among its members in accordance with the allocation methodology established pursuant to Section 65584.04. The purpose of establishing a subregion shall be to recognize the community of interest and mutual challenges and opportunities for providing housing within a subregion. A subregion formed pursuant to this section may include a single county and each of the cities in that county or any other combination of geographically contiguous local governments and shall be approved by the adoption of a resolution by each of the local governments in the subregion as well as by the council of governments. All decisions of the subregion shall be approved by vote as provided for in rules adopted by the local governments comprising the subregion or shall be approved by vote of the county or counties, if any, and the majority of the cities with the majority of population within a county or counties.(b) Upon formation of the subregional entity, the entity shall notify the council of governments of this formation. If the council of governments has not received notification from an eligible subregional entity at least 28 months prior to the scheduled housing element update required by Section 65588, the council of governments shall implement the provisions of Sections 65584 and 65584.04. The delegate subregion and the council of governments shall enter into an agreement that sets forth the process, timing, and other terms and conditions of the delegation of responsibility by the council of governments to the subregion.(c) At least 25 months prior to the scheduled revision, the council of governments shall determine the share of regional housing need assigned to each delegate subregion. The share or shares allocated to the delegate subregion or subregions by a council of governments shall be in a proportion consistent with the distribution of households assumed for the comparable time period of the applicable regional transportation plan. Prior to allocating the regional housing needs to any delegate subregion or subregions, the council of governments shall hold at least one public hearing, and may consider requests for revision of the proposed allocation to a subregion. If a proposed revision is rejected, the council of governments shall respond with a written explanation of why the proposed revised share has not been accepted.(d) Each delegate subregion shall fully allocate its share of the regional housing need to local governments within its subregion. If a delegate subregion fails to complete the regional housing need allocation process among its member jurisdictions in a manner consistent with this article and with the delegation agreement between the subregion and the council of governments, the allocations to member jurisdictions shall be made by the council of governments.(Added by Stats. 2004, Ch. 696, Sec. 6.
