Description
New frontage roads and additional pavement were proposed for the I-94 North-South corridor at many interchanges in Kenosha, Racine and Milwaukee Counties. The additional pavement contributes to increased volume and peak flows of stormwater runoff and eventually decreased water quality. The projects are also in close proximity to wetland and streams.

Our Solution
SSE designed stormwater quality and quantity ponds at 5 interchanges in Racine and Kenosha County, including 2 at the CTH E. Interchange. The ponds are designed with forebays for sediment collection and permanent pools of water with emergent plants on the safety shelf surrounding the ponds. Between storm events, the ponded water in standard wet ponds will warm to temperatures higher than the streams they discharge to. Water leaving the ponds then enters the cooler water streams, creating an unhealthy environment for cold water fish communities. We designed these ponds with submerged outlets to remove the cooler water from the bottom of the pond to minimize this effect.
