Green infrastructure is critical for managing stormwater throughout New York City. Installations such as bioswales and infiltration basins collect and filter stormwater at the source, reducing combined sewer overflows (CSOs), improving water quality, and increasing overall resilience to flooding. EnTech is providing owner’s representative services to the New York City Economic Development Corporation (NYCEDC) for 21 green infrastructure design and construction management contracts.

EnTech is coordinating the design and construction of improvements ranging from small bioswales along right-of-way (ROW), to larger underground installations at city-owned sites such as parks, parking lots, and housing developments. The contracts encompass thousands of green infrastructure installations, totaling more than $405 million, across five watershed areas in the Bronx, Brooklyn, and Queens.

EnTech monitors project schedules and budgets; tracks the progress of multiple contracts simultaneously; and performs site visits to verify conformance with drawings, specifications, and quality standards. EnTech reviews design modifications for consistency with the project scope and advises the NYCEDC and New York City Department of Environmental Protection (NYCDEP) accordingly. The firm expedites permits for client agencies including the New York City Department of Parks and Recreation (NYCDPR) and New York City Housing Authority (NYCHA) for installations on or adjacent to property owned by these agencies.
