E-Designation
An E-Designation (letter "E") assigned to a zoning lot indicates environmental requirements - commonly related to hazardous materials, air quality, and noise - that must be satisfied before a building permit may be issued for development, enlargement, or change of use. NYC materials connect E-Designations to rezoning actions and CEQR-linked environmental requirements.
