Properties that flooded in 1913 and now receive protection from the Miami Conservancy District’s flood protection system pay an annual assessment to cover the necessary, ongoing maintenance of the dams, levees, storage basins, and related parts of the flood protection system. Assessments are based on property values and the appraisal of flood protection benefits provided. The funds collected are used for the necessary, ongoing maintenance of the flood protection system.

 

 

 


Frequently Asked Questions 

 

What is an assessment? Is this a tax?
Properties that flooded in 1913 and are now protected by the Miami Conservancy District flood protection system pay an annual assessment calculated using several factors including property tax values established by the county auditor. 

  • Assessments are different from taxes because assessments provide a benefit such as when you are assessed for sidewalks or streetlights in your neighborhood.
  • You receive a benefit in the form of reduced risk of flooding by the Great Miami River and certain tributaries.

 

Why do I pay a flood protection assessment?

  • Your property flooded during the Great Flood of 1913.
  • The assessment pays for the ongoing maintenance of the integrated flood protection system that includes five dams, storage basins, 55 miles of levee, and improved channels that were constructed to protect the region. 
  • The assessment is based partly on property values determined by the county auditor. The flood protection assessments appear on annual tax bills issued by the county treasurer.

 

Where does the Miami Conservancy District get the authority to charge this assessment? 
MCD is organized under the Ohio Revised Code sections 6101.01-6101.90.

Who pays to be protected?

  • Individual properties pay an annual Individual Assessment

  • Municipalities and counties pay a Unit Assessment. Property owned by a municipality or county is exempt if the property is used expressly for a government purpose such as a city hall, water treatment plant, or fire station.

 

How is the assessment calculated? 

Properties that benefit from the protection of the Miami Conservancy District integrated flood protection system pay an annual assessment. The methodology was developed in 1917 and has been used for more than 90 years. The assessment is calculated by multiplying a rate and benefit:

 

Rate

The rate is assigned annually by the Miami Conservancy District Board of Directors and is subject to approval by the Conservancy Court:

 Maintenance Rate

    • Funds are used for the ongoing operation and maintenance of the flood protection system.
    • Current maintenance rate is 2.19%. The proposed maintenance assessment rate is 2.78% (beginning 2025).

 

Capital Improvement Rate

    • Funds are used for the rehab and repair of the flood protection system.
    • The capital authorization expired in 2022 and the rate was 0.54%. It was limited to dam and concrete stability projects. The proposed capital assessment rate is projected to be at or under 1% (beginning 2025) and will fund work on levees and other flood protection assets, as determined by risk analysis.

 

Benefit

Individual properties, counties, and municipalities that flooded in 1913, and are now protected by the Miami Conservancy District’s integrated flood protection system, receive a benefit. The benefit represents the enhanced value of the property resulting from flood protection and is computed using the following flood factors:

    • Land and building tax values of the property provided by the County Auditor. Since property values can increase or decrease over time, the Miami Conservancy District periodically performs a Readjustment of the Appraisal of Benefits to make sure the cost to maintain the flood protection system is equitably distributed.
    • A flood percentage ranging from 3 to 30%, based on the depth of flooding at the property during the 1913 flood.
    • Other applicable modifiers such as the percent of property that was flooded, the location of structures, and buildings with multiple stories.

If your property is protected by dams, storage basins, and levees, you are fully protected. If your property is protected by dams and storage basins (no levees in your community), you are partially protected, and receive less benefit.

 

Is this related to the county’s reappraisal?
No, it is an entirely different process, but the assessment is based partly on the value of your property.


I’m from a church/non-profit. We should be exempt.
Your property may be exempt from taxes, but it is not exempt from assessments.

Why are there no longer two assessments, Maintenance and Dam Safety, and what is the difference?

  • The Maintenance Assessment is used to operate and maintain the entire flood protection system of dams, levees, storage basins, and other parts of the system. 
  • The Dam Safety Assessment paid for capital improvements from 1999-2022.
  • The Dam Safety Assessment expired in 2022.
  • To fund critical capital improvement projects, the Conservancy Court approved a capital authority for 2025 – 2032, which will result in a second assessment in 2025, called the Capital Assessment, in addition to the Maintenance Assessment.

My property floods so why do I pay an assessment to Miami Conservancy District? You aren’t protecting me.

  • If partially protected: If your property is not within a city that has levees and channel improvements, your property still receives partial protection from the work of the dams. This means that the frequency or intensity of flooding is reduced. You are charged at a partial rate not a full protection rate.
  • If fully protected: Some properties experience minor flooding because their storm sewers lack capacity or sometimes the water is rising levels from groundwater. Miami Conservancy District protects from flooding from the river.

 

Why do I pay twice as much as my next-door neighbor?

  • Your house—because of a difference in ground elevation—may have flooded more or less than your neighbors in 1913.
  • The 1913 flood level at each property is used to calculate the benefit and could impact the amount you pay.
  • Also, property tax values are used to calculate the benefit, so if your house’s appraised value is more than your neighbor’s, you could pay more.

Why did my assessment go up/down?

There are a few reasons that your assessment would increase or decrease:

  • Your property values increased or decreased.
  • Other factors that are used to compute the assessment may have been corrected or updated. Miami Conservancy District used up-to-date computer mapping and database tools to compute the assessment more accurately.
    • For example, the land area of some properties was not 100 percent flooded in the 1913 flood. With up-to-date technology, now we can tell precisely what percentage of the property was wet in 1913 and include that in the equation.

 

What is a Readjustment of the Appraisal of Benefits?

Since property values can increase or decrease over time, the Miami Conservancy District periodically performs a Readjustment of the Appraisal of Benefits to make sure the cost to maintain the flood protection system is equitably distributed. This ensures that individuals and counties are not paying more than their fair share in the distribution of the assessment fees. 

  • The seventh Readjustment of the Appraisal of Benefits will occur in 2024.
  • Updated assessments will be collected in 2025.
  • The current Appraisal Record lists benefits to more than 47,000 individual properties, plus unit benefits to five counties and 22 municipalities along the Great Miami River and its tributaries.
  • The readjustment is used to calculate both the individual and unit assessments.
  • Once final property values are received from the County Auditor, the Miami Conservancy District will calculate the final benefits and assessments in February 2024.
  • Ohio Revised Code §6101.33 allows property owners or public corporations who do not agree with the proposed benefit to object by filing an exception to the readjusted appraisal of benefits. The deadline to file an exception will be 30 days after the Miami Conservancy District public notice. The public notice is anticipated to be issued on March 24, 2024. 

 

How often does a readjustment happen?

  • Ohio Revised Code allows for a readjustment of benefits no more often than every 6 years to ensure that all property owners are only paying their fair share. 
  • The last readjustment was completed in 2012 for assessments collected annually beginning in 2013. The current readjustment will be completed in 2024 for assessments collected annually beginning in 2025.  The rate is set with the intent to not have to raise them for another 8 years.

 

My building wasn’t even here in 1913. How can you assess me?
The property flooded in 1913 and it is now protected by the Miami Conservancy District flood protection system. Properties protected by the flood protection system are assessed for the maintenance of the system.

 

How do you know how deep the flood was on my property in 1913?

Information from topographic mapping (property elevations) and high water elevations surveyed and recorded immediately after the 1913 flood is used to determine flood depth.

 

I have not changed anything in 10 years, why is my assessment increasing?

  • Since 2012, Miami Conservancy District flood protection assessments have been based on 2012 property values.  The readjustment of the appraisal of benefits will use 2023 county auditor property values to calculate updated assessments.
  • The Miami Conservancy District was ordered to complete a readjustment of the appraisal of benefits in 2020 by the Conservancy Court. 

 

What is the flood factor/How do you determine percentage for my flood factor?

  • The flood factor is a percentage that is applied to your benefit calculation. It is based on the 1913 flood depth on your property and the type of protection you receive: either full or partial.
  • Partial protection has a “flood factor” of 3% - this is property not protected by levees.  Typically, this is land outside cities that is not protected by levees but have reduced risk of flooding because of the dams.
  • Full protection “flood factors” range from 6% to 30% and is based on the depth of flooding in 1913. This land is usually in cities that are protected by both the dams and levees to the full design of the system.

 

Why do I have to pay both flood insurance and a Miami Conservancy District assessment?

  • Your assessment helps pay for the maintenance of the flood protection system.
  • Insurance pays in the event you were ever flooded.
  • Some people are subject to mandatory flood insurance, but flood insurance is something that Miami Conservancy District has no control over. We only have authority over the flood protection system.
  • The flood protection system positively influences flood insurance rates.  Miami Conservancy District protected properties have reduced or avoided flood insurance needs.  Without Miami Conservancy District flood protection, you would likely have much higher flood insurance costs.
