The "redetermination of benefits" process is used when a Drainage Authority determines that the original benefits or damages determined in a drainage proceeding do not reflect reasonable present day land values, or that the benefited or damaged areas have changed.
A redetermination of benefits should be viewed similar to determining benefits for a new drainage system. In order to bring benefits in line with current land use practices and land values, viewers need to determine benefits from scratch—as if no drainage system previously existed.
The redetermination of benefits process is most often used to correct problems with outdated viewers’ reports. It may be initiated by the Drainage Authority upon determining that the factors warranting a redetermination exist, with or without any other proceedings (ex. repair or improvement) being proposed.
