New York City Department of Environmental Protection’s (DEP) Green Infrastructure (GI) Program has implemented over 13,000 ROW green infrastructure assets citywide, preventing millions of gallons of stormwater from entering the sewer system and reducing combined sewer overflows (CSO). This presentation provides an in-depth review of the processes followed to implement areawide installation of Precast Porous Concrete Panels (PPCP) from design through construction of contract GKOH15-02. This contract is the first of many areawide PPCP construction that NYC will be implementing as part of its CSO reduction GI program. GKOH15-02 is an active contract that began construction in 2023 and will be completed in 2025. DEP is constructing over 7 miles of PPCP within the parking lane of roadways in the Gravesend Bay neighborhood of Brooklyn. Planning and design took three years, including feasibility studies, siting locations, geotechnical investigations, topographic survey, and development of detailed design drawings and specifications. The speakers will also discuss how these conflicts were resolved during construction. Finally, the presentation will go over cleaning requirements of PPCP during the contractor guarantee period, as periodic cleaning is crucial for proper functionality.
