The drainage of stormwater incident to any residential, commercial, industrial or other development use shall be stored and disposed of on the subject site in accordance with the specifications of the Town Engineer. No site shall be developed in a manner that would cause the discharge of stormwater into a wetland, stream, pond or similar surface water feature, unless the Town Engineer determines that the quantity, quality and other characteristics of the discharge after construction are the same as the characteristics of the discharge from the site in its natural state.[1]
Any outdoor lighting of any use shall be arranged in such a way that no direct glare is cast toward any highway or adjacent property, and luminary devices shall be hooded and/or arranged so that the source of the illumination is not visible from such highway or residential use.
In business and industrial districts, outdoor lighting other than for a permitted sign shall be limited to the illumination of the building for security purposes and to the lighting of parking areas and accessways as necessary for the same movement of pedestrians and vehicular traffic.

The following actions shall be subject to the LWRP: zone changes, subdivisions, site plans, building permits for new buildings, special exceptions, permits for any actions requiring the following variances; land use, height, signage, parking, density or environmentally sensitive lands, and shall not be approved, authorized, issued or altered until the Town Board determines in writing, pursuant to Chapter 151, Art. II of the Town Code, that the action is consistent with the LWRP policies, standards and conditions.
The land use of all nonresidential districts in the local coastal area shall not be expanded, intensified or changed, except to water-dependent uses, unless the Town Board determines that no water-dependent use is feasible and further finds that such change, expansion or intensification of use is consistent with the policies, standards and conditions described in § III of the LWRP.
Natural vegetation shall be preserved and street trees and new plant materials shall be installed for all structures constructed and/or enlarged after the effective date of this provision so that at least 75% of the building that would otherwise be visible from any surface water in the coastal area shall be screened at the time of completion of construction.

§ 322-30 Satellite dish antennas.
[Added 9-11-1984; amended 5-28-1991]
The Town Board finds that dish antennas, due to their shape, opacity and size, create more of a visual impact on the community than do other types of antennas. The intent of these regulations is to permit the reception of satellite transmissions in the Town while simultaneously preventing, avoiding or minimizing the visual contrast of such antennas with regard to the elements of line, form, scale and color.
Ground-mounted installations greater than 10 feet in height shall be screened with evergreen trees located along the antenna's nonreception window axes.
In business and industrial districts, ground-mounted antennas exceeding 10 feet in diameter shall comply with all dimensional requirements for principal buildings.[1]

The change would result in the addition of not more than one lot to the proposed subdivision, provided it does not alter the density of the zoning district.
In making its determination as to granting any area variance, the Planning Board shall grant the minimum variance that it shall deem necessary and adequate and at the same time preserves and protects the character of the neighborhood and the health, safety and welfare of the community. In making such determination, the Planning Board shall consider and render a determination in accordance with the following standards and criteria:
Whether an undesirable change will be produced in the character of the neighborhood or detriment to nearby properties will be created by the granting of the area variance;
Whether the alleged difficulty necessitating the area variance was self-created by an applicant, which consideration shall be relevant to the decision of the Planning Board, but shall not necessarily preclude the granting of the area variance.
