2006 New York Code - Maps And Plans To Be Filed.

 
    §  52.  Maps and plans to be filed.  The board of transportation shall
  cause three similar maps or plans to be made of each parcel of  property
  which  it may deem necessary so to be acquired, or to which there may be
  appurtenant property rights necessary so to be acquired or extinguished,
  designating each of such parcels by a number. Upon each map or  plan  so
  made  or  in  a memorandum accompanying it and to be deemed part thereof
  such board shall cause to be clearly indicated the  particular  property
  rights  to be acquired or extinguished for the purposes of this chapter,
  together with the assessed valuation of the fee on the tax rolls of  the
  city  for each of the three years preceding the date of the approval and
  adoption of such map or plan by such board,  in  relation  to  each  and
  every  piece or parcel of property described upon such map or plan. Such
  board shall have power to cause a triplicate set of maps  or  plans  and
  memoranda  as  herein provided for to be made as often and at such times
  as they shall determine, and each set of maps or plans and memoranda  so
  made shall contain the particulars above enumerated within such district
  as  such  board  shall  in  each  case  provide.  The  maps or plans and
  memoranda provided for by this section, when  approved  and  adopted  by
  such  board,  shall have written thereon a certificate of such approval,
  signed by the members of the board adopting and approving  it,  and  one
  copy  thereof  shall  be  filed  in  the  office of the president of the
  borough, there to remain as a public record, and the other two  sets  of
  maps  or  plans  and  memoranda  shall be transmitted to the corporation
  counsel. Such board, from time to time, may make and file  further  maps
  or  plans  and  memoranda amending those already filed, but not so as to
  defeat or impair any property or interest which shall have been  already
  acquired,  or  to  revive any property right which may have been already
  extinguished by the city.
