N.Y. Rapid Transit Law § 52: 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.
