Official Summary Text

AB 436, as amended, Ransom.
Composting facilities: zoning.
Existing law provides that the Office of
Planning and Research
Land Use and Climate Innovation
serves the Governor and the Governor’s Cabinet as staff for long-range planning and research, and constitute the comprehensive state planning agency. In that capacity, existing law requires the office to, among other things, assist local governments in land use planning. Existing law, the California Integrated Waste Management Act of 1989, establishes the Department of Resources Recycling and Recovery to administer an integrated waste management program. Existing law establishes a goal that statewide landfill disposal of organic waste be reduced from the 2014 level by 75% by 2025.
This bill, on or before June 1, 2027, would require the Office of
Planning and Research,
Land Use and Climate Innovation,
in consultation with the Department of Resources Recycling and Recovery, to develop and post on the office’s internet website, a technical advisory, as provided, reflecting best practices to facilitate the siting of composting facilities to meet the organic waste reduction goals. The bill would require the office to consult with specified entities throughout the development of the technical advisory.
The Planning and Zoning Law requires each county and city to adopt a comprehensive, long-term general plan for its physical development, and the development of certain lands outside its boundaries, that includes, among
other mandatory elements, a land use element that designates the proposed general distribution and general location and extent of the uses of the land for housing, business, solid and liquid waste disposal facilities, and other categories of public and private uses of land, as prescribed.
This bill, upon a substantive revision of the land use element, as specified, on or after January 1, 2029, would require a city, county, or city and county to consider, among other things, the best
practices
practices, sample general plan, and model ordinance
reflected in the technical advisory and to consider updating the land use element to identify areas where composting facilities may be appropriate as an allowable use. By increasing duties on a city, county, or city and county, the bill
would impose a state-mandated local program.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that no reimbursement is required by this act for a specified reason.
