OSTI ID:5539902
The visual impacts of a proposed wind farm near Cape Blanco and Port Orford, Oregon were assessed within the context of Oregon coastal landscapes. The primary alternatives for the wind farm comprised: (1) 31 Boeing MOD-2 horizontal-axis wind turbines and (2) 455 FloWind 170 vertical-axis wind turbines. The visual impacts of a third alternative, consisting of 259 DAF 500 vertical-axis wind turbines, were also examined. The wind farm would lie to the southeast of Cape Blanco, a significant scenic area on the southern Oregon coast and the site of Cape Blanco State Park. The visual impacts of the wind-farm alternatives would vary with the height of the machines and, to a lesser extent, with their number. The MOD-2 alternative would have highly adverse visual impacts because of its size and color. It would also require markings for aircraft warning that would intensify these impacts. The FloWind 170 alternative and the DAF 500 alternative would both also have significant visual impacts in the immediate vicinity of Cape Blanco, but these could be substantially mitigated by deleting a small number of machines in the northeast corner of the project site. The visual impact assessment was checked by conducting public response sessions with Port Orford residents and visitors to Cape Blanco State Park. As well as giving a general confirmation of the technical assessment, the participants indicated that the frequency of their visits to Cape Blanco State Park would not be significantly changed by the constructions of any of the alternatives. Thus, the visual impacts of the wind-farm alternatives appear unlikely to have significant indirect or secondary impacts on recreation or tourism in the project area.
