From the desk of Rohit Aggarwala, NYC DEP Commissioner:
“I’m pleased to announce that the newly updated DEP maps are now complete and ready for use. This has been a major collaborative effort over the past several months, and I want to thank everyone who contributed. These maps represent a significant accomplishment for DEP. They provide a clearer, more comprehensive view of our operations while preserving the high‑level concepts conveyed in previous versions. Here’s a quick overview of the new maps:
• Flood Protection System Map: highlights coastal protection projects under construction or in planning across the city, including East Side Coastal Resilience, Red Hook Coastal Resilience, and South Shore Staten Island.
• Historic Wetlands (addition‑ al content): depicts shore‑ lines, streams, beaches, dunes, tidal marshes, and freshwater wetlands.
• Wastewater System Map: shows the city’s 14 wastewater resource recovery facilities and their sewer sheds. The legend details each plant’s year of construction, capacity, wet‑weather flow, population served, and drainage acreage.
• Wastewater Vessels (additional content): features images of the six sludge vessels, along with harbor survey, shoreline survey, and skimmer vessels.
• Water Delivery System Map: traces the New Croton, Catskill, and Delaware aqueducts from the upstate watershed through Jerome Park and Hillview reservoirs, then into water tunnels No. 1, 2, and 3. The legend also identifies DEP offices, police precincts, labs, customer ser‑ vice facilities, maintenance and repair yards, treatment facilities, and sampling sites.
• Reservoir Flow (additional content): illustrates volume and elevation of the system’s 19 reservoirs, compared to landmarks like the Empire State Building and Statue of Liberty. (A reminder: our system’s engineering brilliance lies in its gravity‑fed design.)
• Water Supply Map: delineates the Delaware, Catskill, and Croton watershed boundaries, including the protected acres and square miles, reservoir locations, aqueduct tunnels, and the city and upstate service areas.
I encourage everyone to begin using these maps in all relevant materials and communications.”
