Calculating Your Proposed Assessment

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)

Look Up Your Proposed Assessment

1. Click on the graphic below to look up your proposed assessment.
2. Enter your County Assessor’s parcel number. If you have more than one property, submit each property individually.
3. Click the submit button.
4. Review your estimated assessment amount. Please note that your proposed assessment will be provided on your official ballot.

Cost of Assessments and Flood Insurance: Calculate the Difference

Compare the costs of your proposed annual assessment for levee improvements and mandatory flood insurance. Plug in your numbers using your proposed assessment rate from the assessment calculator, and the flood insurance chart below:

Potentially, there could be a three-year overlap of mandatory flood insurance and the assessment. Most property owners could qualify for low-cost flood insurance the first year, but rates would increase in year two and beyond.

(Your assessment x 33 years) + (Year 1 Insurance*) +
(Year 2 Insurance** x 2 years) = $ your total

Now, consider the cost of mandatory flood insurance over that same time period, but without levee improvements and the assessment:

(Year 1 Insurance*) + (Year 2 Insurance* X # years left on your mortgage) =
$ your total

What’s the difference?

What you owe on your mortgage	*Flood Insurance: Year 1	**Flood Insurance: Year 2 and Beyond
more than $250,000	$388	$1,484
between $200,000 and $249,000	$361	$1,091
between $150,000 and $199,000	$326	$1,002

EXAMPLE:
Mr. Smith owes more than $250,000 on his house, and has 25 years left on his mortgage. His proposed assessment for levee repairs is $200 per year.

With an assessment and levee improvements:

($200 x 33 years) + ($388) + ($1,484 x 2 years) = $9,956

Now, consider the cost of mandatory flood insurance over that same time period, but without levee improvements (and without the assessment):

($388) + ($1,484 x 24 years) = $36,004

Assessments Vary Depending Upon Location of Property (Relative Flood Risk)

To properly allocate benefit across the district, the project was divided into seven project benefit segments.

Multiple levee failures in each benefit segment were modeled and the resulting 200-year flood inundation areas determined. This analysis resulted in the identification of eleven project benefit areas. (see detailed benefit area map)

Each benefit area is provided protection by a different number of levee segments, based on how floodwaters are expected to flow. There are a maximum of seven possible levee segments that could affect each benefit area.

The relative risk of flooding in each benefit area is determined by:

• Single-family residential property located in the Benefit Area “B”
• Flood Depth Zone 2 to 4 feet
• Parcel size = 0.2 acres
• Building square footage = 1,700 square feet
• Parcel Rate = 26.758 and Building Rate = 0.022387 (outlined in the Draft Preliminary Engineer’s Report)
