Final map approval process and what happens if you miss the deadline

(a) Within one year after the tentative approval of the preliminary map, or such extension of time thereafter, not exceeding six months at a time, as may be granted in writing by the director, the subdivider shall cause the proposed subdivision to be accurately surveyed and a final map thereof to be prepared and stamped by a licensed surveyor in accordance with the rules and regulations and in conformity with the preliminary map and any alterations and changes required thereto. Such final map shall be filed with the director within the period, subject to compliance with all conditions precedent prescribed in the rules and regulations. (b) The director shall approve or disapprove the final map within 45 days after receipt thereof, unless the subdivider waives this requirement and consents to an extension of such period in writing; otherwise, such map shall be deemed to have been approved. Approval of a final map shall be evidenced by the stamp of approval of the director and the director’s signature, or that of an authorized subordinate, on a copy or print of the map. (c) If the final map is disapproved, the director shall communicate in writing the reason for such action to the subdivider. The stamp of disapproval shall be placed on a copy or print of the map. The director shall maintain a record of all disapprovals, including the reasons therefor. (d) Every map approved by the director shall, by virtue of such approval, be an addition to or a detail of the general plan. Approval of the plans shall indicate that the same conform to the subdivision regulations. Approval of a map or a part thereof shall not be deemed to constitute or effect acceptance by the city of any street or other open space shown upon such map. (e) Failure to file a final map within the prescribed period shall automatically terminate all proceedings and the application shall become void. If the subdivider desires to recommence proceedings, the subdivider shall file a new application and submit a new preliminary or final map together with the required filing fees. Any subdivision map so submitted shall be required to conform to any changes or amendments to the rules and regulations or other applicable laws in effect at the time of such filing. )
