If the city council determines either that the map is not in conformity with the requirements of this title; or that it is not satisfied with the plans of subdivision; or if it shall reject any offer or offers of dedication; it shall disapprove the map specifying its reason therefor and the city clerk shall in writing advise the subdivider of such disapproval; and of the reason or reasons for such disapproval. Within thirty days after the city council has disapproved any map; the subdivider may file with the city engineer a map altered to meet the approval of the city council. In such case; the city engineer shall review the altered map for conformance with the requirements of the city council and shall then submit the altered map to the city council for its approval along with a certification that the altered map is technically correct. No final map shall have any force or effect until the same has been approved by the city council and no offer of dedication shall be accepted until the county clerk has recorded the map with the county recorder.
