18.26.025 Action on final map.¶
(A) Approval by City Engineer. Upon receipt of the final map and other data, the map and data shall be referred to the city engineer who shall determine whether the subdivision as shown is substantially the same as it appeared on the tentative map or vesting tentative map, with any approved alterations, and that all provisions of the conditions of approval and this title applicable at the time of approval of the tentative map or vesting tentative map have been complied with, and that he is satisfied that the map is technically correct. If the city engineer determines that full conformity has not been made, he shall advise the subdivider of the changes or additions. If the city engineer determines that full conformity has been made, he shall so certify on the map and transmit the map to the city clerk.
(B) Approval by City Council. At its first regular meeting following the filing of said map with the city clerk as aforesaid, or within thirty days following the filing thereof, the city council shall consider said map, the plan of subdivision and the offers of dedication. The city council may reject any or all offers of dedication.
(1) If the city council determines that said map is in conformity with the requirements of the conditions of approval and this title and that it is satisfied with the plan of subdivision, it shall approve said map provided it is in conformity with the tentative map. When the subdivider has filed with the city clerk any agreement and bonds or deposits required, and when such agreement and bonds and deposits shall have been approved by the city attorney and the city engineer, the city clerk shall certify the map. When all bonds, money or negotiable bonds required under the provisions of this code to secure the payment of taxes and assessments which are a lien on some part of the subdivision but which are not yet payable have been deposited with and approved by the city clerk, (s)he shall transmit the final map to the subdivider to record it in the office of the county recorder.
(2) If the city council determines that the map is not in conformity with the requirements of this chapter and the Map Act, it shall disapprove said map specifying its reason or reasons therefor and the city clerk shall, in writing, advise the subdivider of such disapproval and of the reason or reasons for such disapproval.
(3) Within thirty days after the city council has disapproved any map, the subdivider may file a map altered to meet for approval of the city council. No map shall have any force or effect until the final map has been approved by the city council and recorded in the office of the county recorder, and no title to any property described in any offer of dedication shall pass until the recording of the final map.

18.26.030 Subdivision agreement and performance—Payment—Warrantee bond for¶
improvements required.
(A) Prior to city council consideration of the final map, the subdivider shall execute a subdivision agreement between himself and the city. The agreement shall provide for installation of all improvements as shown on the approved plans and specifications for the project, and specify the period of time within which he or his agent or contractor shall complete all improvement work to the satisfaction of the city engineer. In the event the subdivider fails to complete such work within said period, the agreement shall include provisions for the city to complete all improvements and recover the full cost and expense thereof from the subdivider. Such agreement may also provide the following:
(1) For the construction of the improvements in phases, if applicable and approved by the city council;
(2) For an extension of time under conditions therein specified;
(3) For the termination of the agreement upon the completion of proceedings under an assessment district act for the construction of improvements deemed by the city engineer to be at least the equivalent of the improvements specified in said agreement and required to be constructed by the subdivider.
(B) The subdivider shall also file with the aforesaid agreement, to assure his full and faithful-performance, a financial security for such sum as is deemed sufficient by the city engineer to cover the cost of said improvements and incidental expenses and to cover replacement and repair of existing streets, other improvements damaged in the development of the subdivision, and to cover fees. A labor and materials bond and a separate warrantee bond in amounts satisfactory to the city engineer are also required. Such bonds shall be executed by a surety company authorized to transact a surety business in the state of California and must be satisfactory to and approved by the city attorney as to form and by the city engineer as to sufficiency. In lieu of said bond, the subdivider may deposit with the city treasurer cash in an amount fixed by the city engineer.
(C) In the event the subdivider fails to complete all improvement work in accordance with the provisions of this title, and the city completes it, or if the subdivider fails to reimburse the city for the cost of inspection, engineering and incidental expenses for the work performed, and to cover the cost of replacement and repair of existing streets or other improvements damaged in the development of the subdivision, the city shall call on the surety for reimbursement, or shall appropriate from any cash deposit funds for reimbursement. If the amount of the surety bond or cash deposit is less than all costs and expenses incurred by the city, the subdivider shall be liable to the city for such difference and applicable attorney's fees.
(D) No extension of time, progress payments from cash deposits, or releases of surety bond or cash deposit shall be made except upon certification by the city engineer that work covered thereby has been satisfactorily completed, and upon approval of the city council.
Ord. 98-10 § 1, 1998
18.26.035 Revocation of approvals.¶
If no lots in a subdivision for which a final map has been approved and
recorded under this title prior to the effective date of the ordinance codified in this title have been sold within five years from the date of recording of the maps or if none of the improvements required to be made have been made within two years from the date of recording, the city council may on its own motion hold a public hearing, after notice to all property owners affected to determine whether the approval of such final map should be revoked. If it is determined that such approval should be revoked, the city council shall by resolution revoke such approval without prejudice to the filing of a new map pursuant to this chapter. Such revocation shall be effective upon recording of a certified copy of such resolution in Napa County and thereupon all streets, ways and other easements dedicated or offered for dedication by such map shall be of no further force or effect.
