Article 7 - Building Zones
7-732 - Subdivision Review; Record of Plats.

(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.
