In a press release issued February 2, 2009, The City of New York announced a program to require architects and engineers filing applications for new buildings or major enlargements of existing buildings to upload to the Department of Buildings' website a new Zoning Diagram Form ZD1 and other documents when building plans are filed. The Zoning Diagram will detail "critical information that can be used by the public to determine whether a project is in compliance with required zoning regulations". There will be a thirty-day period following the document upload within which the public can challenge the proposed development. The ZD1 is not required for applications for which the initial document reached "application processed" status prior to March 9, 2009. The press release, announcing that New York is the "First City in the Nation to put Development Diagrams Online", is posted on the City's website at http://www.nyc.gov/html/om/html/2009a/pr055-09.html.
