Several sections of the Thompson Road are historically wet, poorly drained, and/or at too low a grade to avoid periodic flooding from the beaver pond on the west side of the trail. The Contractor will make the following improvements to these areas to make these sections of the Thompson Road sustainable for the long-term, for continued year-round recreational use by walkers, bikers, (and in season) skiers and snowmobilers, as well as for periodic maintenance access by small tractors and trucks: • Restore the ditches in the areas labeled B, C, D, H & I on the attached orthophoto map. • Add 3” minus to the below grade and/or eroded areas of the above-referenced map areas, particularly the longer stretch (H & I). • Improve drainage in these areas by adding/replacing culverts (with beaver protection included on them) as needed.
