Brookside Basin Retrofit

City of Elgin

OBJECTIVE

The City of Elgin owns and maintains several detention facilities designed specifically for flood control. These stormwater basins were constructed many years ago with concrete channels which proved to be high-maintenance. Retrofitting these basins reduces maintenance needs and provides water quality benefits to the community.

PROJECT DESCRIPTION

HLR designed, obtained permits for, oversaw construction, and maintains the Brookside Basin. The basin features native grasses and forbaceous species that were planted in Summer 2016. Benefits of the project include flood water/runoff interception and gradual release back into water table, reduced peak flows for storm events, improved wildlife habitat, reduced sedimentation into Sandy Creek, and improved aesthetics.
