A. 
A vesting tentative map for residential, commercial or industrial development may be filed with the planning commission instead of a tentative map otherwise required by this chapter. The filing and departmental approval, form, and actions pertaining to a vesting tentative map shall be the same as required by this title for other tentative maps, except that the words "vesting tentative map" shall be printed conspicuously on the face of the map.
B. 
In addition to submitting all information required for a tentative map, the following information may also be required with submittal of a vesting tentative map:
1. 
Detailed grading plans;
2. 
Height, size and location of buildings;
3. 
Sewer, water, stormdrain and road details;
4. 
Information on the use to which the buildings will be put.
(Ord. CS 179 §1, 1986)
Planning commission or board of supervisors approval or conditional approval of a vesting tentative map shall confer a vested right to proceed with development in substantial compliance with the ordinances, policies and standards in effect at the time the application for the vesting tentative map is complete and accepted consistent with Government Code Section 66474.2 and as amended or repealed. The rights conferred by this section shall expire if a final map is not approved by the board of supervisors prior to expiration of the vesting tentative map.
(Ord. CS 179 §1, 1986)
The development rights conferred by a vesting tentative map shall remain in effect for two years after the recording of a final map. When multiple final maps are recorded on various phases of a project covered by a single vesting tentative map, the two-year time period shall begin for each phase when the final map for that phase is recorded. At any time prior to the expiration of the two-year time period provided by this section, the subdivider may apply to the planning commission for a one-year extension. If the extension is denied by the planning commission, the subdivider may appeal that denial to the board of supervisors within fifteen days. The time limits and extensions thereof for filing a final map, based on an approved vesting tentative map, shall be the same as for other tentative maps. If the subdivider submits a complete application for a building permit during the initial time period or any approved extension thereof, the rights conferred by a vesting tentative map shall continue until the expiration of that permit.
(Ord. CS 179 §1, 1986; Ord. CS 412 §1, 1990; Ord. CS 470, 1992)
Minor amendments to the vesting tentative map may be approved by the director of planning and community development when it is determined that the proposed changes substantially conform to the approved vesting tentative map. At any time prior to the expiration of the vesting tentative map, the subdivider may apply to the planning commission for an amendment to the map when such amendment does not substantially conform to the previously approved vesting tentative map. If the requested amendment is approved by the planning commission, the development rights conferred by the vesting tentative map shall allow development in substantial compliance with the ordinances, policies, and standards in effect at the time the application for an amendment to the vesting tentative map is complete and accepted consistent with Government Code Section 66474.2 and as amended or repealed. The time limits for filing a final map or maps based on an amended vesting tentative map shall begin on the date such amendment is approved.
(Ord. CS 179 §1, 1986)
If a subdivider files a vesting tentative map for a subdivision whose intended development is inconsistent with the zoning of the property in effect at the time the vesting tentative map is filed, that inconsistency shall be noted on the map. The planning commission may deny such vesting tentative map or approve it conditioned on the subdivider obtaining the necessary change in zoning to eliminate the inconsistency. If the change in zoning is obtained, the approved or conditionally approved vesting tentative map shall confer the vested right to proceed with the development in substantial compliance with the change in zoning and the map as approved.
