Calculating Your Annual Assessment

In June 2010, property owners approved an assessment to pay for SBFCA’s mission to provide 200-year flood protection to urban and urbanizing areas, and 100-year flood protection – or its equivalent – to the southern portion of the Sutter Basin. In accordance with state law, all properties that benefit from the projects necessary to achieving this mission must be assessed. In this case, properties within SBFCA’s boundaries will benefit from the avoidance of flood damages to structures, their contents and to land as a result of levee improvements and other projects designed to reduce flood risk.

The anticipated life of the assessment is 33 years. Each property owner’s assessment will not change from year to year, unless the characteristics of the property change (a vacant parcel is developed, for example). Individual property assessments vary based on:

  • Relative risk of flooding (based on location)
  • Depth of flooding
  • Square footage of structure
  • Size of parcel
  • Land use classification (per County Assessor)

Read the Engineer’s Report for detailed information on assessment rates and methodology.

Assessment Appeals

If you have evidence that your assessment is incorrect, or that your property does not benefit from the avoidance of flood damages to structures and their contents, you may wish to appeal.

November 1 is the deadline for corrections to the current fiscal year’s tax bill. Appeals received after November 1 will be considered for correction in the following fiscal year. Any such corrections, cancellations or refunds shall be limited to current or future fiscal years and shall not be granted retroactively.

Property owners appealing their assessments must notify SBFCA in writing at the Agency’s mailing address (Post Office Box M, Yuba City, CA 95991) or email address ( The Assessor’s parcel number, description of basis of appeal, and any supporting documentation must be included. SBFCA staff will acknowledge receipt of the appeal within five (5) business days, and will inform the property owner of the outcome of the review within fifteen (15) business days. Questions?
