Provisions for public amenities. An applicant for an incentive use permit pursuant to this section shall include in any such application a plan or proposal for the provision of community amenities, including facilities for public use, and whether by transfer, gift, lease, easement or otherwise, to the extent that the same may be acceptable to the Board of Trustees and feasible and adequate, or, in the alternative, by payment of a sum to be determined by the Board of Trustees in lieu of such community amenities, pursuant to Village Law § 7-703. The determination whether any such plan is acceptable, feasible, adequate, or in a form acceptable to the Village shall rest in the sole and unfettered discretion of the Board of Trustees. The Board of Trustees shall have authority to require other or different community amenities or payment in lieu thereof, as it may deem appropriate and as permitted by law.
