City Parking Lot, 201 Main St, Winona MN 55987
These newly renovated rain gardens in the City of Winona Parking Lot (next to the County Government Center, 201 Main St.), are collecting and filtering runoff from the parking lot. The gardens have been here for years, but over time sediment had blocked the curb cuts, leading to pooling of water in the parking lot, and ice buildup in the winter. Water now flows freely into the swale, and up to 6 inches can pool and percolate into the soil, while native plants will grow and their roots will help form channels to help with water infiltration. In an extremely heavy rain, a storm drain at one end can channel excess to keep the garden from over flowing. Thanks to everyone who helped to bring these rain gardens back to function at cleaning our waters.. |
