Brooklyn, NY


A planted berm of grasses and hardy ground covers is developed to protect a building from flooding.

This flood barrier protection project was developed with Build It Back program funding through NYC Department of Housing Preservation (HPD) following Superstorm Sandy. While working with Abel Bainnson Butz, LLP Alison Duncan developed a series of grading and planting concepts for a green berm, fortified with a below-grade concrete barrier wall, that would serve as flood protection for the entrance of a residential buildings at 2650 Ocean Parkway, a property prone to flooding. The design incorporates decorative Cor-ten steel plates to retain the earthen berm where it terminates at the building’s entry path. These steel panels would also support an insert for a deployable gate as required in storm events. An extremely hardy planting regime was proposed to withstand the site’s harsh environmental parameters, including the steep slopes of the berm. In conjunction with the berm, site amenities and finishes were developed for this building’s frontage in the Gravesend neighborhood of southern Brooklyn. Landscape architectural services for Schematic Design through Construction Documents were provided on an expedited schedule.
