Project Description

The New York City Department of Environmental Protection (DEP) is responsible for the City’s drainage plan and stormwater management. In 2012, the NYC DEP revised their rules governing site discharge for new and redeveloped lots. There is now an increased stormwater storage requirement and a stricter limit on the maximum flow off of the property into the combined sewer system. Ultimately, these new requirements are meant to prevent combined sewer discharge from entering into natural water bodies during larger rain events.

DRPILLA’s goal is to design cost-effective and sustainable stormwater management systems that meet both DEP’s new performance standards, as well as our client’s. Our staff will help navigate clients through the various design requirements and associated paperwork involved with the development and redevelopment of various New York City sites.
