The City of Minneapolis has installed over 40 interpretive signs at 26 sites throughout Minneapolis promoting the City’s stormwater management efforts. The signs raise awareness about how these ponds, infiltration basins and rain gardens help protect our waterbodies by improving water quality and reducing flooding.
Local artist Ashley Rades designed the interpretive signs. You can explore a new interactive website to find the stormwater sites and learn more about how they work.
Raingardens, for instance, soak up excess rainwater with their roots and help reduce how much runoff goes into nearby streams and lakes. Infiltration basins, also known as dry ponds, are low-lying grassy areas that become wet ponds during heavy rainstorms after filling with runoff from streets and pipes. The basins absorb the stormwater and remove sediment and garbage before the water flows to streams and the river, helping improve water quality. Ponds help prevent flooding by collecting excess rainwater and slowly releasing it through outlet structures and pipes into streams and rivers.
