Homestake Trail is located within the Whitetail-Pipestone OHV Area This trail is very easily accessible off both the Delmoe Lake Road and other system trails.The successful bidder will most likely encounter visitors.This trail is new construction and will be closed to the public until completed.

Contractors shall wash all equipment to be used on the job prior to mobilizing to the site.The CO, COR, or inspector shall inspect equipment at either the Dillon or Butte Forest Service Offices. Contractors shall call ahead to arrange for inspection at least one day in advance.

Stakes were refreshed in 2015. The Forest Service will be responsible for stake refreshing.

The Contractor is responsible for cleaning up all stakes and flagging at the end of the project and hauling them off National Forest Land. Stakes shall not be removed until after the final inspection unless otherwise allowed by COR

All bridge and puncheon material is government furnished with the exception of nails. Materials shall be onsite on or around July 27th.

In accordance with the I24-permit, no fill material may be placed in or within 10 feet of the stream before, during, or after construction of the bridges, or shallow stream fords.

Grade reversals shall have a minimum of 10 feet in the opposite grade and shall be outsloped to shed water.

Trail Maintenance Logs will not be provided for all trails to be “maintained”. Only the Homestake Trail shall have a trail log.

All other trails are very basic trail reconditioning and cleaning of drainage structures.

A total of 50 drain dips are included on the non-trail log trails. Please see the map on sheet #4 for detailed locations of trails.
