Cal. Sts. & Hy. Code § 969.6
Notwithstanding Section 969.5 or any other provision of this code, if a state of local emergency is declared by the board of supervisors as a result of locally heavy rainfall or flood, the board may authorize the expenditure of road funds for the purpose of emergency repairs to public roads which are not county highways and not in the county maintained system, without obtaining a grant or lease of right-of-way, if the repairs are necessary to provide minimum public access necessary for the protection or preservation of health or safety of residents. The county shall not be responsible for the maintenance of any road so repaired, and it shall not be liable for the condition of the road after the emergency repairs are made.
