Minnkota Power Cooperative

Minnkota Power Cooperative, Inc. near Center, North Dakota, selected Interstate Engineering to perform a site design and provide construction oversight services for the restoration of the plant site’s pavement surface.

Construction of new buildings, chimneys, and other structures at the plant over the last five years had broken the pavement surface in many areas around the site. Site drainage and oversize vehicle weight were the primary concerns of the restoration. In order to meet environmental regulations, drainage from certain areas of the site had to drain to designated settling ponds. The drainage was channeled around the site by means of various valley gutters, high points, break lines, and slopes built into the pavement. The plant site also had permanent erosion control measures that needed to be addressed.
