Check out this dramatic Eco-Priora permeable paver project from Unilock Chicago at Loyola University. The new plaza was designed to allow pedestrians and bicyclists safe passage between the southern areas of the school, which includes the new Institute of Environmental Sustainability building and several student dormitories, and the main campus. The plaza represents a 39,000 square-foot expansion of Loyola’s Lake Shore Campus and builds upon the University’s commitment to sustainability by featuring a new stormwater management system, Eco-Priora permeable interlocking pavers, native plantings, and a meadow living-learning laboratory for students and visitors.

ASCE Releases Committee Report on Permeable Pavements

Permeable Pavements Task Committee

After more than five years of work, a design guidance manual on Permeable Pavements has been published. It was sponsored by the Low Impact Development Committee of the Urban Water Resources Research Council of the Environmental and Water Resources Institute of ASCE. This is a comprehensive guide to permeable pavements for engineers, planners, landscape architects, municipalities, transportation agencies, regulatory agencies, and property owners planning to implement this best management practice for stormwater and urban runoff.

Permeable pavements are considered a green infrastructure practice that offer many environmental benefits, from reduced stormwater runoff and improved water quality to better site design and enhanced safety of paved surfaces. This book offers a detailed overview of the typical permeable pavement systems and includes fact sheets, checklists, and real life case studies that help you to successfully incorporate this highly effective stormwater management system into your design projects. UNI-GROUP U.S.A.'s technical director, Harald von Langsdorff was a contributor on this project.
