Notes: 1. Basemap: ESRI StreetMap North America, 2008.2. This is a color graphic. Reproduction in grayscale may misrepresent the data.3. Shadow-flicker areas and isolines were created using WindPRO 2.9.285 software and associated Shadow module. The model isbased on a "worst case" scenario where the model assumes that there are no clouds, the wind conditions allow for continuous turbine operation, the turbine is always directly between the receptor and the sun, and the turbine is always perpendicular to the sun. These calculations do not take into account the actual location and orientation of windows, or the screening effects associated with existing, site-specific conditions and obstacles such as trees and/or buildings.

Notes: 1. Basemap: ESRI StreetMap North America, 2008.2. This is a color graphic. Reproduction in grayscale may misrepresent the data.3. Shadow-flicker areas and isolines were created using WindPRO 2.9.285 software and associated Shadow module. The model isbased on a "worst case" scenario where the model assumes that there are no clouds, the wind conditions allow for continuous turbine operation, the turbine is always directly between the receptor and the sun, and the turbine is always perpendicular to the sun. These calculations do not take into account the actual location and orientation of windows, or the screening effects associated with existing, site-specific conditions and obstacles such as trees and/or buildings.4. Potential turbine visibility based ontopography and screening effects ofmapped forest vegetation. Analysis based on maximum blade tip height of 152.4 meters.
