Cal. Gov. Code § 65098.4
Prior to the issuance of a certificate of occupancy, a facility operator shall establish and submit for approval to the planning director or equivalent position for the city, county, or city and county a truck routing plan to and from the state highway system based on the latest truck route map of the city, county, or city and county. The truck routing plan shall describe the operational characteristics of the use of the facility operator, including, but not limited to, hours of operation, types of items to be stored within the building, and proposed truck routing to and from the facility to designated truck routes that, to the greatest extent possible, avoid passing sensitive receptors. The truck routing plan shall include measures, such as signage and pavement markings, queuing analysis, and enforcement, for preventing truck queuing, circling, stopping, and parking on public streets. The facility operator shall be responsible for enforcement of the truck routing plan. A revised truck routing plan shall be submitted to the planning director or equivalent position prior to a business license being issued by the city, county, or city and county for any new tenant of the property. The planning director or equivalent position shall have discretion to determine if changes to the truck routing plan are necessary, including, but not limited to, any additional measures to alleviate truck routing and parking issues that may arise during the life of the facility.
