Visual Impact

The State of Vermont has a scoring system for possible adverse visual impact of small wind turbines from two different vantage points [17]: private property (the neighbors' view) and public views (roads, recreation, and natural areas). For the neighbors' view the considerations are: (1) What is the position of the turbine in the view? (2) How far away is the turbine seen? (3) How prominent is the turbine? (4) Can the turbine be screened from view? For public views there are two additional considerations: (5) Is the turbine seen from an important scenic or natural area? (6) What is the duration of the view? Each is rated by a point system (Table 9.1), with a total of 12 points for the residential
