Natomas Floodplain Remapping Update

As of June 16, 2015, the City has obtained a new flood insurance rate map to provide Natomas with an A99 flood zone designation.

In 2005, FEMA reinforced the agency’s long-standing regulation to ensure that levee owners or communities document that a levee meets federal standards for protection against the one-percent-annual-chance flood. After re-evaluation of the levees by the US Army Corps of Engineers, FEMA remapped the Natomas Basin area into a floodplain with an AE flood zone designation in December 2008.  The AE flood zone designation required elevating or flood-proofing structures at or above the 100-year floodplain, which would be up to 20 feet in some areas. This caused a de-facto building moratorium. Now, the City has an A99 flood zone designation. A99 is an interim flood zone designation, which is still considered a high risk flood zone, but allows construction in Natomas, with local conditions.

For information regarding building in Natomas, please visit the City of Sacramento's Community Development Department.

Important Flood Insurance Information

Property owners in the Natomas Basin who have a federally-backed mortgage will still need flood insurance as the levee improvements are not complete. The A99 status allows the majority of property owners located within the Natomas Basin to receive a Preferred Risk Policy (PRP).

The A99 flood zone rates are currently significantly higher than the “Preferred Risk Policy” rates, so property owners are encouraged to consult their insurance agent for information about their flood insurance policy and for a flood insurance premium quote.
