in the Vermillion River and its tributaries; track project<br />
grant, matching funds and expenditures; and complete<br />
required reporting.<br />
Mississippi River – Winona<br />
Downtown Winona Pre-Mississippi River Rain Garden<br />
– 2015<br />
Sponsor: Port Authority of Winona<br />
Funding: Clean Water Partnership (Grant) $41,324<br />
Purpose: This project will protect the Mississippi River at<br />
Winona, MN by the installation of a downtown Winona<br />
parking lot rain garden. This project will improve the<br />
Mississippi River water quality by removing an incorrectly<br />
sloped, 100% impervious parking lot surface then<br />
regrading and resurfacing the parking lot to direct runoff<br />
into a central rain garden planted with deep-rooted<br />
native vegetation that will filter pollutants such as oil,<br />
grease, dirt, debris, broken glass, road salt, sand and<br />
unseen nutrients before any runoff reaches Winona’s<br />
stormwater system and the Mississippi River. The rain<br />
garden will also serve to slow the velocity of runoff and<br />
reduce the likelihood of flooding which is a regular<br />
concern in Winona.<br />
Zumbro River<br />
Zumbro River Ultra-Urban Vol-TSS-FeC Reduction –<br />
2014<br />
Sponsor: City of Rochester<br />
Funding: Section 319 (Grant) $300,000<br />
Purpose: Reduce turbidity and fecal coliform bacteria<br />
loading in the receiving waters for downtown Rochester<br />
by identifying feasible volume control locations in the<br />
project area and demonstrating green infrastructure<br />
designs, benefits, and maintenance practices before<br />
redevelopment opportunities arise. In addition to<br />
delineating these areas, volume control practices need<br />
to be demonstrated to help “sell” their effectiveness and<br />
attractiveness and to clarify their maintenance needs.<br />
