Measurable Outcome(s)

The finished project consists of a main bio-infiltration cell and a second basin to hold runoff before it enters the wetland complex. This bio-infiltration basin will annually remove an estimated 864 pounds of sediment, 2.5 pounds of phosphorous, and 10.88 pounds of nitrogen.

Project Overview

At 410 acres, Lake Owasso is the largest lake in the Grass Lake Water Management Organization (GLWMO) and one of the most pristine. Maintaining the lakes water quality is a priority for the GLWMO. A long urbanized area along Aladdin Street in Roseville currently lacks stormwater features to remove pollutants and reduce water volume. The rainwater from this area drains directly to a wetland which is hydrologically connected to Lake Owasso. Adjacent to the residential area is a 0.5 acre parking lot which drains into a ditch which eventually enters the same wetland. The rainwater that runoffs from the parking lot also lacks treatment facilities, and due to an extreme change in grade, is causing major erosion problems. In a cooperative effort, the Grass Lake Watershed Management Organization, Ramsey Conservation District and City of Roseville came up with a solution. The parking lot runoff will be re-routed so it enters the adjacent residential stormwater conveyance system. A bio-infiltration basin will then be installed to capture and treat the combined rainwater runoff from both sites. This bioinfiltration basin will annually remove an estimated 864 lbs of sediment, 2.5 lbs of phosphorous, and 10.88 lbs of nitrogen, which would have otherwise entered the wetland. The project is scheduled to be completed during the 2011 construction season.
