Existing law, the Permit Streamlining Act, governs the approval process that a city or county is required to follow when approving, among other things, a permit for construction or reconstruction for a development project for a wireless telecommunications facility and a collocation or siting application for a wireless telecommunications facility. This bill would require a local agency to allow, except as provided, microtrenching for the installation of underground fiber if the installation in the microtrench is limited to fiber. The bill would also require, to the extent necessary, a local agency with jurisdiction to approve excavations to adopt or amend existing policies, ordinances, codes, or construction rules to allow for microtrenching. The bill would provide that these provisions do not supersede, nullify, or otherwise alter the requirements to comply with specified safety standards. The bill would authorize a local agency to impose a fee for its reasonable costs on an application for a permit to install fiber, as provided. By imposing new duties on local agencies with regard to the installation of fiber, the bill would impose a state-mandated local program. The bill would include findings that changes proposed by this bill address a matter of statewide concern rather than a municipal affair and, therefore, apply to all cities, including charter cities. 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.
