The Impact of Wind Power Projects on Residential Property Values ...

Data Collection and Summary
County Assessor Debbie Collins and mapping specialist Karen Owen were extremely helpful in
gathering data and answering questions at the county level. Data were obtained directly from the
county and from Visual Lease Services, Inc and OKAssessor, where representatives Chris Mask,
Terry Wood, Tracy Leniger, and Heather Brown helped with the request.
All valid single-family residential transactions within five miles <strong>of</strong> the nearest wind turbine and
occurring between July 1996 and June 2007 were included in the dataset, resulting in 1,113
sales. 107 <strong>The</strong>se sales ranged in price from $11,000 to $468,000, with a mean <strong>of</strong> $100,445.
Because <strong>of</strong> the relatively recent construction <strong>of</strong> the facility, 58% <strong>of</strong> the sales (n = 637) occurred
before construction, leaving 476 sales with possible views <strong>of</strong> the turbines. Of those 476 sales, 25
had more-dramatic view ratings than MINOR and 17 sales occurred inside <strong>of</strong> one mile.

107 Portions <strong>of</strong> the town <strong>of</strong> Weatherford, both North and South <strong>of</strong> the town center, were not included in the sample
due to lack <strong>of</strong> available data. <strong>The</strong> homes that were mapped, and for which electronic data were provided, however,
were situated on all sides <strong>of</strong> these unmapped areas and were similar in character to those that were omitted. None <strong>of</strong>
the unmapped homes were within a mile <strong>of</strong> the nearest wind turbine.
