SUMMARY
Northern States Power Company is requesting site plan approval for an electrical substation to provide for
present and future power needs of the eastern Rosemount area. The property will remain owned by Koch
Refining Company. The property is zoned Agriculture, and is guided for General Industrial use by the
Comprehensive Guide Plan. The Essential Service Facilities ordinance permits substations in both the
Agriculture and General Industrial Districts.
The enclosed area is set back 100 ft. from the 140th Street East right-of-way. The yard in between contains a
six-foot high berm on either side of the entry drive. Landscaping on and in front of the berm consists of a
combination of boulevard trees, evergreen and ornamental trees. Planning Staff is satisfied that the proposal is
consistent with the requirements for screening contained in the newly adopted ordinance (July 15, 1997)
regulating Essential Service Facilities.
The transmission line route extends north, behind the substation to the edge of the old Chicago Northwestern
railroad ROW. At that point, it turns west and follows the railroad into the interior of the Koch Refining
Company complex.
On August 12, 1997, the Planning Commission conducted the public hearing as required.
