The document provides a detailed framework for 'restorative redevelopment' in the Nine Mile Run Watershed, focusing on shifting from conventional 'end of the pipe' stormwater conveyance to site-based infiltration and treatment. It details conceptual designs for four representative sites—Hunter Park, Edgewood Crossroads, Regent Square Gateway, and Sterrett School—and proposes a comprehensive policy framework to overcome institutional barriers to green infrastructure.

The report presents a model for urban watershed restoration in the Pittsburgh region, specifically focusing on the 6.5 square mile Nine Mile Run watershed. It argues for 'restorative redevelopment,' which embeds the removal of stormwater from sewer systems into the incremental process of urban renewal. By using 'green infrastructure'—such as bioretention areas, porous pavements, and cisterns—the model aims to reduce combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs) while providing community benefits like beautification and recreational amenities. The report details four sample designs (Hunter Park, Edgewood Crossroads, Sterrett School, and Regent Square Gateway) that meet specific hydrologic and budget criteria, and recommends the establishment of a permanent coordinating body to manage the watershed across municipal boundaries.
