Toll Brothers’ Gowanus Canal Development, Brooklyn
Categories: Uncategorized

Gowanus Canal DevelopmentToll Brothers wanted to build a residential development on the west side of the Gowanus Canal between Carroll and Second Streets in an area of Brooklyn  prone to combined sewer overflow (CSO) events. While with a previous firm, Mr. Schaffer prepared a NYCDEP Drainage Proposal and calculations for the proposed residential development. The proposed stormwater management strategy included green roofs and permeable courtyard surface.  The site was severely constrained by the relative elevations of the discharge point, mean high water, and existing buildings to remain. Since the site is located adjacent the tidally influenced Gowanus Canal and is predominantly located within the Federal Emergency Management Agency (FEMA) 100-year floodplain, site grading and drainage is a critical component to the site’s design. Since the area is prone to CSO events, separate storm sewers will be constructed as part of the proposed project in the streets adjacent to the proposed project, as well as two new storm sewer outfalls. The firm was retained by Toll Brothers to provide site/civil engineering and environmental consulting services related to the proposed residential development.
