High-Voltage Transmission Lines: Proximity, Visibility, And Encumbrance Effects‪.‬

ABSTRACT In this study, over 1,200 home sales in 1998-2007 are aggregated into four study areas with a 345-kV transmission line. Field data are collected on the sale properties relative to proximity to and visibility of transmission line towers, and the extent of encumbrance by a transmission line easement. A multiple regression model is used to test whether the sale prices are affected by line proximity, tower visibility, or property encumbrance. In both continuous distance and distance zone models. the proximity and visibility variables typically fall to be statistically significant. The only variable that appears to have any systematic effect is the encumbrance variable; however, its magnitude is generally small.
