Whenever a subdivider files a vesting tentative map for a subdivision whose intended development is inconsistent with the zoning ordinance in existence at the time, the subdivider shall also apply for the necessary change in the zoning ordinance to eliminate the inconsistency. Until the change in the zoning ordinance is obtained, the vesting tentative map shall not be approved. The approval or conditional approval of the vesting tentative map may be granted only simultaneously with or after the necessary changes in the zoning ordinance. (Ord. 1905, § 1, 7/10/1990)
