As noted during your recent inspection, the location of <br />the road, and use by loaded concrete trucks can result in localized road damage and drainage concerns under <br />high runoff or muddy conditions. Our review of the road design and configuration indicates that these concerns <br />can be effectively addressed by widening the road in certain areas, providing better roadside drainage, installing <br />3 additional culverts, and establishing sediment traps to capture road surface runoff and contain excess <br />sediment. We also determined that additional room is needed for snow removal and storage to minimize the <br />potential for maintenance - related disturbance of adjacent areas paralleling the road corridor. <br />We propose to expand the permitted road disturbance corridor from its current permitted width of 40 feet, to 75 <br />feet. Where the required road improvements dictate, we will strip additional soil material, and will also strip <br />selected areas adjacent to the road for snow removal and storage. The additional soil material recovered will be <br />placed in the existing soil material stockpiles for future use in reclaiming the road. <br />This submittal includes revised PAP text and maps /drawings addressing both the expanded road disturbance <br />corridor and proposed road improvements. New and revised PAP materials are identified by the enclosed <br />Summary of Revisions /Additions. TCC would like to proceed with this project as soon as possible, therefore we <br />appreciate your consideration and cooperation in facilitating timely review and approval.
