Title
Aquatic Weed and Aerator Maintenance - Change Order #3 and Addendum D
History
In 2022, Public Works contracted with McCloud Aquatics (contract #20230012) to manage aquatic weeds in thirty-seven (37) Village-owned basins and maintain five (5) aerators. This original contract value was $159,367.00 for three (3) years of service to the Village’s basins, and included no contingency amount. In 2024, Public Works increased the contract value twice with Change Orders #1 for $11,000.00 and Change Order #2 for $7,600.00, for a total contract value increase of $18,600.00.

Mill Creek is not currently managed as part of McCloud’s aquatic weed contract, but has experienced excessive lily pad growth in the last several years that has been a nuisance to the nearby residents.
