(Ord. No. 3411 § II.)
Sec. 23A-52. - Private Project Approval: Mandatory Findings and Statement of Overriding Considerations.
(a)
The FEIR shall be certified by the Decision Making Body no later than one (1) year after the project application is accepted as complete except as provided by Section 15109 of the Guidelines. In the event that circumstances justify additional time and the project applicant consents thereto, the one (1) year period may be extended by the Planning Director for an additional ninety (90) days. In the event additional time is needed for combined State and Federal compliance, the one (1) year period may be extended in accordance with Section 15110 of the Guidelines.
(b)
In accordance with Section 15091 of the Guidelines, no Decision Making Body shall approve a private project for which an EIR has been completed which identifies one (1) or more significant effects of the project unless the Decision Making Body makes one (1) or more of the written findings contained in Section 15091(a) of the Guidelines for each of those significant effects. Each such finding shall be accompanied by a statement of the facts supporting the finding. Otherwise, no Decision Making Body shall approve a private project as proposed unless such action is in compliance with Section 15092 of the Guidelines.
(c)
In the event that the Decision Making Body approves a project which will result in the occurrence of significant effects which were identified in the FEIR but are not at least substantially mitigated, the Decision Making Body shall state in writing the specific reasons to support its action based on the FEIR or other information in the record in accordance with Section 15093 of the Guidelines. This statement shall explain how the Decision Making Body balanced the merits of approving the project with the environmental damage which will result.
(d)
In the event that subsequent changes are proposed in a project which will require important revisions of the previous EIR or Negative Declaration due to the involvement of new significant environmental impacts not addressed in the previous EIR or Negative Declaration on the project, then a revised environmental document shall be processed in accordance with this ordinance and the information contained therein shall be reviewed and considered prior to approval of said changes.

The County body with actual decision making authority shall, prior to taking action on the project, review and consider the adequacy of the environmental documents and the information contained therein and make such findings required by Sections 15091, 15092, and 15093 of the Guidelines as may be necessary. The Decision Making Body may hold a public hearing on the environmental documents. In such case notice of any hearing held by the Body with actual decision making authority shall be given by one of the methods set forth in Section 15087 of the Guidelines at least ten (10) days prior to the commencement of the hearing.

Where the County disagrees with the lead agency's proposal to prepare a Negative Declaration for a project, the county should identify the significant environmental effects it believes could result from the project and recommend either that an EIR
be prepared or that the project be revised to avoid or mitigate all significant effects to a point where 1) clearly no significant effects would occur or 2) there is no substantial evidence that significant effects would occur.

As soon as possible after receiving a notice of preparation of an EIR but in any event no later than forty-five (45) days after receiving such notice, the county shall inform the lead agency in writing sent by certified mail or equivalent procedure of the scope and context of the environmental information that the county would need in an EIR.

(e)
Prior to reaching its decision on the project, the county shall consider the environmental effects of the project as shown in the environmental documents. If an EIR has been prepared for the project and such EIR indicates a significant effect of activities which the county will carry out or approve in the project, the county will ensure that such effects are avoided or mitigated as in (b) above. In approving any portion of the project, the county shall make the findings required by Section 15091 and 15092 of the Guidelines for each significant effect of the project and, if necessary, shall make a statement of overriding considerations in accordance with Section 15093 of the guidelines.
