Q. Even considering all of those factors or weaknesses, what is your conclusion regarding the impact on residential property values from the proposed project? A. Under certain circumstances as described in my report, the negative impact may be similar. Also, in significant view loss situations, as described in my report, I would conclude that, within a reasonable degree of professional certainty, land values may be negatively impacted 17% - 20%. Editor's Note: Mr. Zarem argues that the appropriate methodology for estimating the 'view' impact of industrial wind turbines on property values is 'paired data analysis'- defined in the The Dictionary of Real Estate Appraisal as: “A quantitative technique used to identify and measure adjustments to the sale prices or rents of comparable properties; to apply this technique, sales or rental data on nearly identical properties are analyzed to isolate a single characteristic’s effect on value or rent.” In the absence of relevant view/turbine data, he derived an alternative paired data analysis for determining view impacts on property values due to wind turbines from Transmission Line view impacts on the prices of single-family residential lots in subdivisions...as...sufficient paired data isolating the effects of view loss due to Transmission Lines exist in the marketplace to reach reasonable conclusions as to market tendencies. This data isolates impacts due to view loss associated with Transmission Lines.
