Section 7-732. Subdivision review; record of plats

1. Filing of plat with
  county clerk or register. (a) No plat of a subdivision of  land  showing
  lots,  blocks  or sites, shall be filed or recorded in the office of the
  county clerk or register until it has been approved by a planning  board
  which  has  been empowered to approve such plats. Further, such approval
  must be endorsed in writing on the plat in such manner as  the  planning
  board may designate.
    (b)  Such  endorsement shall stipulate that the plat does not conflict
  with the county official map, where one exists, or in cases where  plats
  do  front  on  or  have  access  to or are otherwise related to roads or
  drainage systems shown on the county official map, that  such  plat  has
  been  approved in the manner specified by subdivision two of section two
  hundred thirty-nine-f of the general municipal law.
    2. Notification of filing. It shall be the duty of the county clerk or
  register to notify the planning board in writing within  three  days  of
  the  filing  or  recording  of any plat approved by such planning board,
  identifying such plat by its title, date of  filing  or  recording,  and
  official file number.
    3.  Effect  of  filing.  After  such  plat  is approved and filed, the
  streets, highways and parks shown on such plat shall  be  and  become  a
  part of the official map or plan of the village.
    4.  Cession  or  dedication  of  streets,  highways  or parks. (a) All
  streets, highways or parks shown on a filed or recorded plat are offered
  for dedication to the public unless the owner of the affected  land,  or
  the owner's agent, makes a notation on the plat to the contrary prior to
  final  plat  approval.  Any  street, highway or park shown on a filed or
  recorded plat shall be deemed to be private until such time  as  it  has
  been formally accepted by a resolution of the local legislative body, or
  until  it  has been condemned by the village for use as a public street,
  highway or park.
    (b) In the event that such approved plat  is  not  filed  or  recorded
  prior to the expiration date of the plat approval as provided in section
  7-728  of this article, then such offer of dedication shall be deemed to
  be invalid, void and of no effect on and after such expiration date.
