Sacramento-San Joaquin Valley.

Existing law requires each city and county within the Sacramento-San Joaquin Valley, within 24 months of the adoption of the Central Valley Flood Protection Plan, to amend its general plan to include specified data, policies, and implementation measures. The city or county is also required, within 36 months of the adoption of the Central Valley Flood Protection Plan, but not more than 12 months after the amendment of its general plan, to amend its zoning ordinance to be consistent with the general plan, as amended. After the general plan amendments and zoning ordinance amendments have become effective, the city or county, unless it makes one of 3 specified findings, is prohibited from approving specified permits that would result in specified construction located within a flood hazard zone, and is required to deny approval of a tentative map, or a parcel map for which a tentative map was not required, for a subdivision located within the flood hazard zone. This bill would include, among the findings that exempt a city or county from the above-described prohibition and requirement, a finding that property in an undetermined risk area has met the urban level of flood protection based on substantial evidence in the record.
