A brief history of water consumption in the New York City Water Supply System (Based on New York City Census population)

NYCDEP Citywide Hydrants

The daily capacity and percent of capacity filled for each of the City's reservoirs.

Harbor water sampling information

Clean Air Tracking System (CATS) is online application with end-to-end process where NYC Residents can submit for New Boiler Registration, Boiler Registration Renewal, Affidavit, Amendment, Boiler Work Permits, Inspection requests, Emergency Engine, Generator Registration, Gas Stations, Industrial Work Permits. For additional context, please go to this link: https://a826-web01.nyc.gov/DEP.BoilerInformationExt/ as the external source to this dataset.

The data tables summarize the turbidity values, coliform, fluoride and chlorine found at sides in distribution each month.

 ACP7 form is an asbestos project notification. Any time asbestos abatement is perform on quantities greater than a minor project amount, the applicant has to file this form with DEP Asbestos Control Program (ACP). All asbestos documents are filed through the Asbestos Reporting and Tracking System (ARTS) E-file system. This system is web based and entirely paperless. All information on the ACP7 is essential to meet the requirements setforth in the asbestos rules and regulations Title15, Chapter 1 (RCNY). ACP enforcement staff utilizes this form for inspection of asbestos abatement activities.

NOTE: This file includes data for all 5 boroughs and has a size of 4.60 GB. Individual borough files are available for download from the metadata attachments section.

Citywide Geographic Information System (GIS) land cover layer that displays land cover classification, plus pervious and impervious area and percentage at the parcel level, separated into 5 geodatabases, one per borough. DEP hosted a webinar on this study on June 23, 2020. A recording of the webinar, plus a PDF of the webinar presentation, accompany this dataset and are available for download. Please direct questions and comments to DEP at imperviousmap@dep.nyc.gov.

Data collected to fulfill the requirements of the SWTR (Surface Water Treatment Rule) and FAD (Filtration Avoidance Determination). Data is collected via grab sampling, analysis, LIMS data capture and reporting. Each record represents either a four hour turbidity result, a 24 hour average turbidty result, or a daily fecal coliform result from DEL18DT (Delaware Shaft 18 downtake). Data is used to monitor compliance with the requirements above. There are no limitations for the data.

New York City’s Municipal Separate Storm Sewer System (MS4) Stormwater Management Program is a multiagency effort led by the Department of Environmental Protection (DEP) to reduce pollution in stormwater runoff in the MS4 Area of NYC. This MS4 Map represents the known MS4 outfalls and drainage areas as of August 1, 2020 and provides additional data relevant to the MS4 Permit. The MS4 map only shows areas draining to the Municipal Separate Storm Sewer System. DEP also maintains combined sewer and sanitary sewer systems; these service area delineations are not represented on this map. More information about the MS4 Stormwater Management Program is available at www.nyc.gov/dep/ms4

A collection of citywide Geographic Information System (GIS) layers that show areas of potential flooding scenarios under varying sea level rise conditions. Please see the New York City Stormwater Resiliency Plan for more information about the methodology applied to develop the maps. Please direct questions or comments to StormwaterResiliency@cityhall.nyc.gov.

This collection contains the following NYC Stormwater Flood Maps:

• NYC Stormwater Flood Map - Extreme Flood (3.66 inches/hr) with 2080 Sea Level Rise


• NYC Stormwater Flood Map - Moderate Flood (2.13 inches/hr) with 2050 Sea Level Rise


• NYC Stormwater Flood Map - Moderate Flood (2.13 inches/hr) with Current Sea Levels


• NYC Stormwater Flood Map - Limited Flood (1.77 inches/hr) with Current Sea Levels
