N.Y. Comp. Codes R. & Regs. tit. 19, § 900-2.9
(a) A visual impact assessment (VIA) to determine the extent and assess the significance of facility visibility. The components of the VIA shall include identification of visually sensitive resources, viewshed mapping, confirmatory visual assessment fieldwork, visual simulations (photographic overlays), cumulative visual impact analysis, and proposed Visual Impacts Minimization and Mitigation Plan as outlined in subdivision (d) of this section. The VIA shall address the following issues:
(b) The viewshed analysis component of the VIA shall be conducted as follows:
(4) In developing the application, the applicant shall confer with municipal planning representatives, the office, and where appropriate, OPRHP and/or APA in its selection of important or representative viewpoints. Viewpoint selection is based upon the following criteria:
(v) assessment of visual impacts pursuant to the requirements of adopted local laws or ordinances.
(c) Visual contrast evaluation.
(3) Each set of existing and simulated views of the facility shall be compared and rated and the results of the VIA shall be summarized. Documentation of the steps followed in the rating and assessment methodology shall be provided including results of rating impact panels and a description of the qualifications of the individuals serving on the panels. Where visual impacts from the facility are identified, contrast minimization and mitigation measures shall be identified, and the extent to which they effectively minimize such impact shall be discussed.
(d) Visual impacts minimization and mitigation plan.
The visual impacts minimization and mitigation plan shall include proposed minimization and mitigation alternatives based on an assessment of mitigation strategies, including screening (landscaping), architectural design, visual offsets, relocation or rearranging facility components, reduction of facility component profiles, alternative technologies, facility color and design, lighting options for work areas and safety requirements, and lighting options for FAA aviation hazard lighting. The facility design shall incorporate the following measures for the visual impacts minimization and mitigation plan:
(6) Shadow flicker for wind facilities. Shadow flicker shall be limited to 30 hours per year at any non-participating residence, subject to verification using shadow prediction and operational controls at appropriate wind turbines. The visual impacts minimization and mitigation plan shall include:
(9) A lighting plan(s), which shall address:
(iii) exterior lighting design shall be limited to lighting required for health, safety, security, emergencies and operational purposes and shall be specified to avoid off-site lighting effects as follows:
Exhibit 8 shall contain:
