2006 New York Code - Official Map, Changes.

 
    § 29. Official  map,  changes. Such legislative body is authorized and
  empowered, whenever and as often as  it  may  deem  it  for  the  public
  interest,  to change or add to the official map of the city so as to lay
  out new streets, highways or  parks,  or  to  widen  or  close  existing
  streets,  highways or parks.  Drainage systems may also be shown on this
  map. At least five days' notice of a  public  hearing  on  any  proposed
  action  with  reference  to  such  change  in  the official map shall be
  published at least once in an official publication of said city or in  a
  newspaper  of general circulation therein. No change in the official map
  shall be made for the lay out of a new street or the opening or widening
  of any street unless notice shall have been  sent  by  registered  mail,
  return  receipt  requested,  to the person and address noted on the last
  preceding real property tax notice issued on the property which is to be
  included in such proposed layout, opening or widening of  such  streets.
  Before  making  such  addition or change the matter shall be referred to
  the planning board for report thereon, but if the planning  board  shall
  not  make  its  report  within  thirty  days of such reference, it shall
  forfeit the right further to suspend action.  Such additions and changes
  when adopted shall become a part of the official map of  the  city,  and
  shall  be deemed to be final and conclusive with respect to the location
  of the streets, highways and parks shown thereon.
    The layout, widening or  closing,  or  the  approval  of  the  layout,
  widening  or  closing  of  streets,  highways or parks by the city under
  provisions of law other than those contained in this  article  shall  be
  deemed  to  be  a  change  or addition to the official map, and shall be
  subject to all the provisions of this article.
