Guiding principles, rights and powers of the Town Board in reviewing special permit requests. The Town Board, where specified in Article III of this chapter, shall have the power to approve, disapprove or approve with conditions special use permit authorizations. Such conditions shall conform with the principles and standards for certain special use permits set forth in this section and elsewhere in this chapter. Additional conditions may be established within the discretion of the Town Board, except that such additional conditions shall not be arbitrary or capricious, but within the discretion of said Board as necessary to protect the public health, safety and welfare of the Town of Hamptonburgh. Such conditions may include, but are not limited to, the establishment of a periodic review procedure in order to ensure that any special use permit approval requirements are being observed. The Town Board may, where necessary, deviate from the existing specific requirements set forth in § 150-15 of this article upon a specific finding that such deviation is both necessary to permit the use of said property and also that such deviation is no less protective of public health, safety and welfare; is not detrimental to adjoining properties and existing uses or permitted uses within such properties; will not create hazardous or obnoxious conditions; is approvable by any other municipal, county, state or federal agency having jurisdiction over the proposed use; and will not compromise the other explicit goals of this chapter, including, but not limited to, the orderly flow of traffic, protecting scenic areas and enhancing the visual appearance of the Town and protecting the established character and social and economic well-being of both private and public property.
