Established in 2009, The Rooftop Community Garden built on the roof of the St. Louis County Motor Pool Garage and funded in collaboration between St. Louis County and the Northeast MN Sustainable Development Partnership. The purpose was to control runoff water from the former parking area on the rooftop, catching and recycling the water and keeping it from directly draining on to the streets and into Lake Superior. 15 raised beds were built with a drainage and containment system including two 500 gallon tanks where water is treated and then re-used by the gardeners to grow organic vegetables. The other 1/2 of the roof is planted with perennial sedums.
