California Code, Government Code - GOV § 65964

(a) Require an escrow deposit for removal of a wireless telecommunications facility or any component thereof.  However, a performance bond or other surety or another form of security may be required, so long as the amount of the bond security is rationally related to the cost of removal.  In establishing the amount of the security, the city or county shall take into consideration information provided by the permit applicant regarding the cost of removal.

(b) Unreasonably limit the duration of any permit for a wireless telecommunications facility.  Limits of less than 10 years are presumed to be unreasonable absent public safety reasons or substantial land use reasons.  However, cities and counties may establish a build-out period for a site.

(c) Require that all wireless telecommunications facilities be limited to sites owned by particular parties within the jurisdiction of the city or county.
