Project Goals and Purpose -- Stream Corridor
map by John O'Lear, Forest Preserve Dist. of Cook Co.
The stream bank was previously trenched to facilitate rapid run off of rainfall into the
in Wolf Road Prairie. The stream bed and banks were eroded and supported little vegetation.
Culverts had also been placed in the stream corridor to channel runoff and drainage.
In the 1950s a small bridge was constructed over the trench to provide access
to the back of the property where
there is a small cabin in the woods.
The purpose was to remediate the artificial drainage by creating a grassed waterway to slow
the flow of water from the upstream 275 acre Hinsdale-Sexton Landfill. The restoration creates
meanders in the contours of the
stream bed and allows for the revegetation of native grasses, sedges and wildflowers whose root
systems anchor the soil.
The newly created swales retain rainfall and
purify water passing through
the system. This returns the stream to a more historic ecological function.
