(Ord. 1080 §1(part), 1986)

16.12.150 - Conditions for approval.

The advisory agency or otherwise duly authorized hearing body may approve the tentative map if it finds that all the following conditions exist:

A.

The map is complete and complies with the subdivision improvement standards;

B.

The proposed subdivision is consistent with the general plan and applicable specific plans, and meets the requirements of the subdivision improvement standards and relevant provisions of the county zoning ordinance, excepting subsection (L) of this section;

C.

The site of the proposed subdivision is physically suitable for the type of development and density proposed;

D.

The design of the subdivision and proposed improvements are not likely to cause substantial environmental damage, substantially and avoidably injure fish or wildlife or their habitat, or cause public health problems;

E.

The design of the subdivision and the type of improvements will not conflict with easements acquired by the public at large for access through, or use of, property within the proposed subdivision, or, if such conflict does exist, that alternate easements will be provided and that these will be substantially equivalent to ones previously acquired by the public. ("Easements," as used in this subsection, refers only to easements of record or to easements established by judgment of a court of competent jurisdiction.);

F.

If the waste from the proposed subdivision is to be discharged into an existing community sewer system, such discharge will not result in violation of existing requirements of a Regional Water Quality Control Board;

G.

If the subdivision is a land project, there exists a specific plan for the land to be subdivided;

H.

If the preliminary soils report required by the subdivision improvement standards indicates the presence of critically expansive soils or other soil problems which, if not corrected, would lead to structural defects, the action recommended by the civil engineer preparing the soils report is likely to prevent structural damage to each structure to be constructed;

I.

If the subdivision fronts on a lake owned entirely or in part by a public agency, or on a public waterway, reasonable public access by fee or easement from a public highway to that portion of the bank of the river,

stream, or lake bordering or lying within the proposed subdivision is available, either through or across the subdivision itself, or within a reasonable distance from the subdivision;

J.

If the subdivision fronts on a public waterway, a public easement providing reasonable public access along a portion of the bank of the river or stream bordering or lying within the proposed subdivision has been or will be dedicated or a finding has been made that such access is not in the best interest of the general public and the landowner.

K.

If the subdivision is to be created by the conversion of residential real property into a condominium project or a community apartment project, the findings required by Section 66427.1 of the Government Code have been made. If all the above conditions do not exist, then the planning commission may conditionally approve the map subject to satisfying the above conditions or may disapprove the map. In addition, the planning commission may condition approval of the map on such measures as will promote and protect the public health, safety, comfort, convenience, and general welfare. The planning director shall inform the subdivider of the commission's decision.

L.

Whenever a subdivider files a tentative map for a subdivision whose intended development is inconsistent with the Zoning Ordinance in existence at that time, that inconsistency shall be noted on the map. The county may deny such a tentative map or approve it conditioned on the subdivider, or his or her designee, obtaining the necessary change in the Zoning Ordinance to eliminate the inconsistency. If, in the case of vesting tentative maps only the change in the Zoning Ordinance is obtained, the approved or conditionally approved tentative map shall confer the vested right to proceed with the development in substantial compliance with the change in the Zoning Ordinance and the map, as approved.

(Ord. 1080 §1(part), 1986)

16.12.160 - Special conditions for vesting tentative map.

A.

The 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 described in Government Code Section 66474.2. However, if Section 66 474.2 of the Government Code is repealed, the 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 vesting tentative map is approved or conditionally approved.

B.

Notwithstanding subsection A, a permit, approval, extension, or entitlement may be made conditional or denied if any of the following are determined:

A failure to do so would place the residents of the subdivision or the immediate community, or both, in a condition dangerous to their health or safety, or both;

2.

The condition or denial is required in order to comply with state or federal law.

C.

The rights referred to herein shall expire if a final map is not approved prior to the expiration of the vesting tentative map as provided in Section 16.16.04. If the parcel or final map is approved, these rights shall last for the following periods of time:

1.

An initial time period of one (1) year;

2.

A subdivider may apply for a one year extension at any time before the initial time period expires;

3.

If the subdivider submits a complete application for a building permit during the periods specified in subsections 1 and 2 the rights referred to herein shall continue for an additional month.
