For example, the bill sent out in December of 2016, due and payable by January 31, 2017, is based on the 2016 assessment year.

Appealing Your Assessment to the Board of Review
Reassessment notices are mailed out in April of each year, assuming a change in the value of the property has occurred. Property owners then have the option to review City assessments during the open book period, which is normally held at the end of April each year. Should a property owner feel his/her assessment is in error, they have the right to appeal their assessment before the Board of Review.
The Board consists of council members serving the second year of their council term, as well as the City Manager. The Board of Review is normally held in May of each year. Once the Board closes for the year, no changes can be made to current year assessments.
