Applicant – City of Coeur d’Alene
The City of Coeur d’Alene proposes installing treatment to remove discharge from the city’s stormwater outfalls. This project aims to install stormwater storage/filter systems and/or vegetated swales to divert stormwater from the existing outfalls in this 131-acre urban drainage area. An engineering study will determine the best storage and filtration method for the site. The city is requesting $380,000 for this outfall project. It would reduce phosphorus by 235 lb per year, yielding 2,350 lbs/10years (in perpetuity) for a cost-benefit ratio of $160 per lb per 10 years.
