Floodplain Preservation

The Great Flood of 1913 devastated the Miami Valley along the Great Miami River, killing hundreds and causing $100 million in damage (nearly $2 billion in today’s economy). Today, The Miami Conservancy District’s (MCD) flood-protection system has prevents flooding, saving property owners from the mess, stress and financial loss of flooding.

Properties that flooded in 1913 and now benefit from MCD’s flood-protection system pay an annual assessment to cover the necessary, ongoing maintenance of the dams, levees and related flood-protection features; and a Dam Safety assessment for capital improvements to the dams. Assessments are based on a variety of factors including property tax values established by the county auditor. Properties that receive full flood protection from the dams and levees have a greater benefit and, in general, pay a higher assessment than properties that receive a reduction of flooding (not full protection) from the dams.

Since property tax values can increase or decrease over time, MCD periodically performs a readjustment of the benefits to make sure that the cost to maintain the flood-protection system is equitably distributed. MCD completed its latest readjustment in 2004, the first since 1996.

If you are a property owner, you may use this system to determine your 2005 assessment.
