A 700 foot portion of South Owasso Boulevard is currently a gravel road with no curb, gutter, or storm sewer to effectively manage and treat stormwater. The City has identified this area as a direct discharge to Lake Owasso as all stormwater drains to the lake without any treatment. The City will be installing a material called PaveDrain that will provide a hard surface to drive on, but also permeable to allow stormwater to drain through into a rock base. Once stormwater is in the rock base, it will be filtered before it is discharged to the lake by an underdrain and City storm sewer. The filtering process will treat the stormwater and remove pollutants that degrade the lakes water quality. This process will also slow the rate at which stormwater reaches the lake, which will help with local drainage and flooding concerns.
The City advertised for bids in November of 2016. Seven bids were submitted and the City Council awarded the low bid in the amount of $346,324 to Ramsey Excavating. The project is expected to begin in June and will likely take four weeks to finish.
This project is being funded through a combination of Storm Water Utility Funds, property owner assessments, and a grant from the Ramsey-Washington Metro Watershed District.
During construction, access may be limited for residents on South Owasso Boulevard for short periods of time.
