New Laws (3) Index
A. 
General. The center line of the traveled portion of the road shall be placed in the center of the right-of-way, and shall be located in the field by a state-licensed land surveyor. Suitable construction ties shall be established at all control points, which shall be protected during construction so that the center line may be re-established at any time. See § 187-13C(1).
B. 
Stations. Stations shall be established every 50 feet and at all radius points (P.C. and P.T.'s). The beginning of this line shall be located in the gutter line of the intersected road and shall be designated as Stations 10+0. A construction stake shall be placed at right angles to each station, clear of construction and grading. This stake will show the station on the side facing toward Station 10+0, the measured distance to center line (offset) on the side facing away from Station 10+0, and on the face nearest to center line the cut or fill which will establish the center line grade. A grade list showing the stations, stake elevations, offset from center line grade, cuts and fills shall be provided to the Town's Construction Inspector by the applicant, or his designee who is to have charge of the construction layout, before construction begins.
C. 
Benchmarks. A permanent benchmark shall be established at the beginning and end of each road and at intervals not exceeding 500 feet along the length of the road. These benchmarks shall be referenced to the same datum shown and identified on the construction drawings for the road. Sketches showing at least three ties to each benchmark, the benchmark elevation and a description of each benchmark shall be provided to the Town's Construction Inspector.
D. 
Protection of stakes and benchmarks. Grade stakes and permanent benchmarks shall be protected and preserved until the road construction has been approved by the Board of Selectmen or the Town Engineer. If such stakes or benchmarks are disturbed, they shall be replaced immediately.
A. 
Clearing. All trees, brush, boulders, structures, walls, fences, perishable matter and debris of whatever nature shall be cleared from the full width of the right-of-way, including areas necessary for cuts and fills, construction of storm drainage systems, and required sight lines, except that valuable shade trees may remain in shoulder areas as provided for in Subsection C.
B. 
Grubbing. All roots, stumps and brush within the clearing limits specified in Subsection A above shall be grubbed and excavated. All stumps shall be chipped, or disposed of off site in a lawful manner. No stumps shall be buried on site.
C. 
Trees. Valuable shade trees may be permitted by the Commission to remain in shoulder areas as provided for in § 187-28F, but not within three feet of any curbline, if no substantial increase in the risk of injury or damage results by reason of a tree's presence in the particular place where it stands, and a written opinion is provided from a qualified arborist stating that the long-term health of the tree will not be adversely impacted by proposed construction or proximity to proposed road improvements. Any such tree shall be effectively protected and preserved so as to insure that it will suffer no damage during construction operations. All tree branches overhanging the roadway pavement or shoulder areas shall be trimmed by a qualified arborist to a clearance of 16 feet above the finished grade of the road.
D.
