South Lake Owasso Drainage Improvements Project

Overview


A 700 foot portion of South Owasso Boulevard was a gravel road with no curb, gutter, or storm sewer to effectively manage and treat stormwater.  The City identified this area as a direct discharge to Lake Owasso as all stormwater drains to the lake without any treatment.  The City installed a material called PaveDrain that provided 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 project is complete.

Assessments


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.  The City Council will be asked to approve the project assessments at a public hearing on Monday, October 9, 2017 at 6:00 p.m. in the Council Chambers at City Hall, 2660 Civic Center Drive.  Once approved, the pre-payment period for this assessment is from October 10 to November 15.  All assessments not paid by that date will be sent to Ramsey County for payment with next year’s taxes.
