Multiple (or phased) final maps may be permitted in accordance with Section 66456.1 of the Map Act. The number of phased final maps may be determined by the advisory agency. If the subdivider does not depict phase lines on the tentative map or the phase lines shown on the tentative map change prior to filing with the city council, and prior to recordation of a final map(s), the city engineer may require installation of appropriate improvements prior to recordation of the final map or any phase to ensure public safety and orderly development, including, but not limited to, providing secondary access.
