This workshop highlights successful large scale, on-the-ground restoration efforts that are re-connecting aquatic habitats fragmented by dams, road crossings, and other man-made alterations in the Upper Great Lakes. Tools and strategies will be shared for planning, financing, and articulating results, including the mutual benefits of restoring streams, improving community infrastructure, and creating local jobs.

Cost estimates are important for prioritizing projects • Excavation • Pipe (bevel and polymer coating) • Bedding and fill (including raised road elevation) • Road surfacing • Haul away old pipe and unusable fill • Riprap, silt fence • Dewatering / pumping • Project administration and surveysHOW Cleveland 2012 Page 11
