Mercer Stormwater Detention Basin is Now Complete!

The Mercer Stormwater Detention Basin features two dry-bottom compartments and provides an estimated 512 acre-feet of stormwater storage — that is roughly the equivalent of 512 football fields covered in one foot of water.

A stormwater detention basin temporarily holds stormwater during heavy rain events to help reduce the risk of flooding in the area.
