An E-Designation is a NYC zoning map designation that indicates the presence of an environmental requirement pertaining to potential Hazardous Materials Contamination, Window/Wall Noise Attenuation, or Air Quality impacts on a particular tax lot.  E-Designations are established on the Zoning Map by the Department of City Planning (DCP) and City Council as a part of a zoning change/action.

E – Designations are created through changes in real-estate zoning. Areas of Potential Environmental Concern are outlined on proposed zoning maps and E – Designations are assigned to lots within these areas.  An E – Designation for noise refers to areas where there are high levels of ambient noise (Window/Wall Noise Attenuation) and an E – Designation for air refers to Sites designated as having potentially high levels of air emissions. The E – Designation process for HAZMAT differs in several ways from the E – Designation process for noise and air. An E – Designation for HAZMAT refers to Sites where hazardous materials may be present.


E -Designations are not required to be resolved if no alterations to the Subject Property are being made, however, once new construction or a change in land use is planned for an E – Designation Site, the E – Designation has to be addressed before any changes can be made.
