(c) The legislative body shall not adopt or extend any interim ordinance pursuant to this section unless the ordinance contains legislative findings that there is a current and immediate threat to the public health, safety, or welfare, and that the approval of additional subdivisions, use permits, variances, building permits, or any other applicable entitlement for use which is required in order to comply with a zoning ordinance would result in that threat to public health, safety, or welfare. In addition, any interim ordinance adopted pursuant to this section that has the effect of denying approvals needed for the development of projects with a significant component of multifamily housing may not be extended except upon written findings adopted by the legislative body, supported by substantial evidence on the record, that all of the following conditions exist:

1. (1) The continued approval of the development of multifamily housing projects would have a specific, adverse impact upon the public health or safety. As used in this paragraph, a “specific, adverse impact” means a significant, quantifiable, direct, and unavoidable impact, based on objective, identified written public health or safety standards, policies, or conditions as they existed on the date that the ordinance is adopted by the legislative body.
2. (2) The interim ordinance is necessary to mitigate or avoid the specific, adverse impact identified pursuant to paragraph (1).
3. (3) There is no feasible alternative to satisfactorily mitigate or avoid the specific, adverse impact identified pursuant to paragraph (1) as well or better, with a less burdensome or restrictive effect, than the adoption of the proposed interim ordinance.
