When a subdivision is developed adjacent to a freeway or expressway as shown on the general plan, the City Council may require the subdivider to dedicate and improve a frontage road to provide ingress and egress to adjacent lots or to create backup lots which front upon an interior residential street and back up to such freeway or expressway. When backup lots are created the subdivider shall waive direct access rights from the lots to the freeway or expressway and shall construct a masonry wall, fence or other suitable barrier as required by the City Council between the subdivision and the adjacent freeway or expressway.
