(1) Existing law grants the legislative body of a city certain powers with respect to city streets and highways, including the power to construct and maintain those streets and highways. Existing law grants the board of supervisors of a county general supervision, management, and control of county highways and authorizes the board of supervisors to lay out, construct, improve, and maintain county highways. This bill would prohibit a city or county from holding a community input meeting to reconsider, delay, or prevent implementation of a proposed pedestrian or bicycle safety project after that project has passed 90% design, as specified. After or upon the award of a contract for, or when county or city staff, as applicable, are directed to begin, the construction of a pedestrian or bicycle safety project, the bill would prohibit the city or county from terminating the project unless the city or county makes at least one specified finding at a public meeting. If a city or county establishes a process for residents of the city or county to submit a petition to request the installation of a traffic-calming measure, the bill would prohibit the city or county from requiring the petition to contain the signatures of more than a majority of the total number of persons whose residences are located, in whole or in part, within 1,000 feet of the proposed traffic-calming measure, as specified. To the extent that the bill increases the duties of local officials, the bill would impose a state-mandated local program. (2) Existing law, the Pedestrian Mall Law of 1960, authorizes the legislative body of a city or county to establish a pedestrian mall, as defined, and prohibit vehicular traffic on the mall, upon adoption of an ordinance establishing the mall. The California Environmental Quality Act (CEQA) requires a lead agency, as defined, to prepare, or cause to be prepared, and certify the completion of, an environmental impact report on a project that it proposes to carry out or approve that may have a significant effect on the environment or to adopt a negative declaration if it finds that the project will not have that effect. CEQA also requires a lead agency to prepare a mitigated negative declaration for a project that may have a significant effect on the environment if revisions in the project would avoid or mitigate that effect and there is no substantial evidence that the project, as revised, would have a significant effect on the environment. CEQA, until January 1, 2040, exempts from its requirements certain transportation-related projects, including, among others, pedestrian and bicycle facilities, as specified. CEQA requires, except as provided, those exempted projects to be carried out by a local agency and meet certain requirements, including certain labor requirements. This bill would exempt from the requirements of CEQA the establishment or expansion of a pedestrian mall and would require those projects to comply with the above-described requirements applicable to those exempted CEQA projects. (3) 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. (4) 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, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.
