Official Summary Text

SB 639, Ashby.
Zoning: Sacramento-San Joaquin Valley.
Existing law requires each city and county within the Sacramento-San Joaquin Valley to amend its general plan relative to the data and analysis contained in the Central Valley Flood Protection Plan, as specified and to amend its zoning ordinance consistent with the general plan.
Existing law prohibits the legislative body of a city or county within the Sacramento-San Joaquin Valley from entering into a development agreement for property that is located within a flood hazard zone after the amendments described above are complete unless the city or county makes a specified finding. Among the possible findings, is that the local flood agency has made adequate progress on construction of a flood protection system that will result in flood protection equal to or greater than the urban level of flood protection in urban or urbanizing areas intended
to be protected by the system, which, except as provided, shall be achieved by 2025 for urban and urbanizing areas protected by project levees.
Existing law similarly prohibits each city and county within the Sacramento-San Joaquin Valley from approving a discretionary permit or other discretionary entitlement that would result in the construction of a new building or construction that would result in an increase in allowed occupancy for an existing building, or a ministerial permit that would result in the construction of a new residence, for a project that is located within a flood hazard zone after the amendments described above are complete unless the city or county makes a specified finding. Among the possible findings, is that the local flood agency has made adequate progress toward the urban level of flood protection as described above.
Existing law similarly requires the legislative body of each city and county
within the Sacramento-San Joaquin Valley to deny approval of a tentative map or a parcel map for a subdivision that is located within a flood hazard zone after the amendments described above are complete unless the city or county makes a specified finding. Among the possible findings, is that the local flood agency has made adequate progress toward the urban level of flood protection as described above.
This bill would include in the exceptions to the requirement that the urban level of flood protection be achieved for urban and urbanizing areas protected by project levees by 2025, specified areas located in the City of Marysville, the City of Sacramento, the County of Sacramento, the County of Sutter, and the County of Yuba that shall, instead, be required to achieve the urban level of flood protection by 2030. The bill would authorize the Department of Water Resources to require a city or county listed above to contribute its fair and reasonable share of any
property damage caused by a flood in its respective jurisdiction, as specified, until the city or county finds the area has met the urban level of flood protection. The bill would make a related technical change.
This bill would make legislative findings and declarations as to the necessity of a special statute for the County of Sacramento, County of Sutter, County of Yuba, City of Marysville, and City of Sacramento.
