The City is responsible for protecting its citizens and public safety personnel from potential emergency flood situations by warning of any flooding or high water danger while guaranteeing adequate information about changing high water and flood conditions.

This agreement was terminated in May 2020 in anticipation of the current proposed Interlocal Agreement for an updated forecasting system. The City has received regular updates and demonstrations from SARA regarding the new flood modeling system since SARA initiated their current flood modeling process in 2019.
