Completed Projects

Huntsdale Basin Retrofit 

Oasis Kwik Wash Basin Retrofit 


P1010813 - Copy

Water quality improvements in and around this detention basin in Huntsdale Subdivision were funded by the Dry Branch Watershed 319 Grant. Video 

This car wash detention basin was not functioning and had maintenance issues from trash and standing water. Pavement runoff is now filtered through native plants in this bioretention basin.

Pervious pavement, athletic field biofilters, a native meadow, and parking lot bioswales help filter pollutants from runoff before it gets to the park's seven-acre lake. The lake forebay traps mud and trash coming with runoff from 500 acres of development along I-70 and Wentzville Pkwy.
