Underground Electric Lines
Section R. 460.512 - Extensions of residential distribution and service lines in the lower peninsula mainland

(1) The distribution system in a new residential subdivision and an existing residential subdivision in the lower peninsula mainland in which electric distribution facilities have not already been constructed shall be placed underground, except that a lot facing a previously existing street or county road and having an existing overhead distribution line on its side of the street or county road shall be served with an underground service from these facilities and shall be considered a part of the underground service area.

(2) The owner or developer of such subdivisions shall be required to make a nonrefundable contribution in aid of construction to the utility in an amount equal to the sum of the lot front-foot measurements multiplied by an amount to be fixed or changed in appropriate rate-making proceedings, which amount shall be considered to be the difference in cost between overhead and direct burial underground facilities.

(3) The front-foot measurement of each lot to be served by a residential underground distribution system shall be made along the contour of the front lot line. The front lot line is that line that usually borders on, or is adjacent to, a street. However, when streets border on more than 1 side of a lot, the shortest dimension shall be used. In case of a curved lot line that borders on a street or streets and represents at least 2 sides of the lot, the front-foot measurement shall be considered as 1/2 the total measurement of the curved lot line. Where a lot is served by an underground service from an overhead distribution line under the provision of rule 2(1), the lot front-foot measurement of the lot to be served shall be deleted.

(4) The construction provided for in subrule (2) includes the extension of electric distribution facilities to the lot line of each lot in the subdivision.

(5) The use of the lot front-foot measurement in these rules shall not be construed to require that the underground electric distribution facilities be placed at the front of the lot.

(6) The utility shall install, own, and maintain the service line from the property line to the customer's meter.

(7) For a normal installation, the developer or customer shall make a contribution in aid of construction to the utility in an amount equal to the product of the straight line distance in feet from the termination of the utility's facilities at the front or rear property line to a point directly below the customer's meter multiplied by an amount to be fixed or changed in appropriate rate-making proceedings. Where special routing of the service line is required by the customer, this amount per foot will apply to the route of the line as installed.
