California Code, Public Resources Code - PRC § 30610.91

(a) The Legislature finds and declares that designing and building complete streets that safely accommodate the needs of nonmotorized vehicles, pedestrians, and motorized vehicles in the coastal zone is preferred and encouraged.

(b) In order to expedite the provision of safe, nonvehicular travel within urbanized areas for the purpose of increasing recreational public access to the coast, limiting vehicle miles traveled, and reducing greenhouse gas emissions, an application by a local government to convert an existing motorized vehicle travel lane into a dedicated bicycle lane, dedicated transit lane, or a pedestrian walkway, shall not require a traffic study for the processing of either a coastal development permit or an amendment to a local coastal program.

(c) If a proposal to convert an existing motorized vehicle travel lane into a dedicated bicycle lane, dedicated transit lane, or a pedestrian walkway within the developed portion of an existing road right-of-way requires an amendment to a local coastal program, the amendment shall be processed pursuant to subdivision (d) of Section 30514, if the executive director determines that, on balance, the project will provide additional public access benefits without significantly reducing existing public access opportunities.
