The Timely, comprehensive and effective mitigation of the “north pipe” storm sewer system as defined in previous planning discussions by the MPRB as the “open channel” option. Lake Hiawatha receives tons of trash and myriad pollutants that dump directly into the Lake via the north pipe storm sewer.
