(O4060; O2006-10)
A. 
In recommending approval or conditional approval or in approving or conditionally approving a tentative map, the Planning Commission and Council shall find:
1. 
That the proposed subdivision, together with the provisions for its design and improvement, is consistent with the General Plan and any applicable specific plan; and
2. 
Except for condominium conversion projects where no new structures are added, that the design of the proposed subdivision provides, to the extent feasible, for future passive or natural heating or cooling opportunities in the subdivision, as described in the State Subdivision Map Act and any guidelines promulgated by the Council.
B. 
In recommending disapproval or in disapproving, or in recommending approval or in approving at a lower density of a housing development project which is in compliance with the applicable plans, zoning and development policies in effect at the time the project's application was determined to be complete, the Planning Commission and Council shall make written findings based upon substantial evidence in the record that both of the following conditions exist:
1. 
The housing development project would have a specific, adverse impact upon the public health or safety unless the project is disapproved or approved upon the condition that the project be developed at a lower density;
2. 
There is no feasible method to satisfactorily mitigate or avoid the adverse impact identified other than disapproval of the housing development project or approval upon condition that the project be developed at a lower density.

In recommending approval or conditional approval or in approving or conditionally approving a tentative map for the conversion of a mobile home park to another use pursuant to Government Code Section 66427.4, the Planning Commission and Council shall be required to:
1. 
Take steps to mitigate any significant adverse impact of the conversion on the ability of displaced mobile home park residents to find adequate space in a mobile home park by zoning for additional replacement housing;
2. 
Find that there already exists land zoned for replacement housing or adequate space in other mobile home parks for those residents who will be displaced;
3. 
Require the subdivider to take steps to mitigate any significant adverse impacts of the conversion on the ability of the displaced mobile home park residents to find adequate space in a mobile home park; or
4. 
Make a finding, based upon substantial evidence, that mitigation pursuant to subsections (C)(1) and (3) is not feasible. As used in this section, "feasible" means capable of being accomplished in a successful manner within a reasonable period of time, taking into account economic, environmental, social and technological factors.
D. 
The Planning Commission may recommend denial and the Council may deny approval of the tentative map on any grounds provided by law including without limitation, if they find that the discharge of waste from the proposed subdivision into an existing community sewer system would result in, or add to, violation of existing requirements prescribed by a state regional water quality control board. A tentative map shall be denied if any of the following findings are made:
1. 
That the proposed map is not consistent with the General Plan and applicable specific plans;
2. 
That the design or improvement of the proposed subdivision is not consistent with the General Plan and applicable specific plans;
3. 
That the site is not physically suitable for the type of development;
4. 
That the site is not physically suitable for the proposed density of development;
5. 
That the design of the subdivision or the proposed improvements are likely to cause substantial environmental damage or substantially and avoidably injure fish or wildlife or their habitat;
6. 
That the design of the subdivision or the type of improvements are likely to cause serious public health problems;
7. 
That the design of the subdivision or the type of improvements will conflict with easements of record or easements established by court judgment, acquired by the public at large, for access through or use of property within the proposed subdivision. In this connection, the Council may approve a map if they find that the alternate easements for access or for use will be provided and that those will be substantially equivalent to ones previously acquired by the public;
8. 
That all requirements of the California Environmental Quality Act and the rules and procedures adopted by the Council pursuant thereto have not been met;
9. 
That the proposed map fails to meet or perform any of the requirements or conditions of this title or the State Subdivision Map Act, unless the Council finds that such failure is a result of a technical and inadvertent error which does not materially affect the validity of the map;
10. 
That the applicant has failed to submit complete or adequate information.
Any applicable time limits for acting on the tentative map may be extended by mutual consent of the subdivider and Planning Commission or Council. A waiver of applicable time limits may be required of the subdivider to permit concurrent processing of related project approvals or environmental review of the same project.
