Thompson Oaks River to River Greenway and Water Quality Design

When an underutilized golf course closed, Dakota County saw an opportunity to create a new segment in the River to River Greenway Trail. But first, they had to address construction debris that had been buried across the site prior to its use as a golf course. The County reached out to our team to help.

We developed a remediation plan and design concepts that considered stormwater management, water quality, and access and connectivity for pedestrians and cyclists. Our plan resulted in the screening of more than 10,000 truckloads of impacted soil as well as restoration of the wetlands and a portion of the creek.

The site manages runoff from 25 percent of West St. Paul, preventing 93 pounds (42 kilograms) of phosphorus from reaching the Mississippi River each year. In addition to these water quality improvements, a new boardwalk bridge serves an iconic landmark for the regional trail and, along with two trail loops, provides opportunities to enjoy wildlife, wetland, and waterfall views.

Located near a library, multi-family development, and future amphitheater, this restoration project has become a popular community destination.
