J. OVERHEAD HIGH-VOLTAGE TRANSMISSION LINES
No dwelling or related property improvement may be located
within the engineering (designed) fall distance of any pole,
tower or support structure of a high-voltage transmission
line, radio/TV transmission tower, microwave relay dish or
tower or satellite dish (radio, TV cable, etc.). For field
analysis, the appraiser may use tower height as the fall
distance.
For the purpose of this Handbook, a High-Voltage Electric
Transmission Line is a power line that carries high voltage
between a generating plant and a substation. These lines
are usually 60 Kilovolts (kV) and greater, and are
considered hazardous. Lines with capacity of 12-60 kV and
above are considered high voltage for the purpose of this
Handbook. High voltage lines do not include local
distribution and service lines.
Low voltage power lines are distribution lines that commonly
supply power to housing developments and similar facilities.
These lines are usually 12 kV or less and are considered to
be a minimum hazard. These lines may not pass directly over
any structure, including pools, on the property being
insured by HUD.
