Cal. HSC § 2863

When any nuisance is found to exist on any property subject to the control of any state or local agency, the district shall notify the state or local agency of the existence of the nuisance. Sections 2858, 2860, 2861, 2861.5, and 2862 shall govern the contents of the notice and the manner of serving it, the right of the state or local agency to a hearing before the board, the hearing before the board, and the power of the district to abate the nuisance if it is not abated by the state or local agency. If the state or local agency determines that the order to prevent recurrence of the breeding specified in the notice to abate the nuisance is excessive or inappropriate for the intended use of the land, or if the state or local agency determines that a nuisance, as specified in Section 2800.5, does not exist, the agency may appeal the decision of the board to the State Director of Health Services within 10 days subsequent to the hearing. The director shall decide the matters on appeal and convey his or her decision to the agency and district within 30 days of the receipt of the appeal. The decision of the director shall be final and conclusive. If the control of the nuisance is performed by the district, the cost for that control is a charge against, and shall be paid from, the maintenance fund or from other funds for the support of the state or local agency.

Any state or local agency and a district may enter into contractual agreements to provide control of nuisances. The authority which is granted by this paragraph is in addition to any other authority which a state or local agency and a district may have to enter into contractual agreements for the control of public nuisances, as defined in Section 2800.5.

As used in this section, “state agency” means an agency defined in Section 11000 of the Government Code, and “local agency” means a city, county, city and county, district, or other public corporation.
