   (c) All surveys for the establishment of property lines, right of way lines and permanent easements shall tie into at least two (2) points in the Devens Survey Control Network. For traverse/level adjustments the published values of these existing control points shall be held fixed.

   (d) All information submitted in digital format shall adhere to the standards of the MassDevelopment Engineering office.

2. Monumentation
   (a) Monuments shall be installed on way lines and property lines at all points of curvature and at all points of change in direction.

   (b) Monuments shall be a standard permanent granite bound of not less than four feet (4') in length and not less than six inches (6") in width and breadth and shall have a one half inch (1/2") diameter hole one and one half inches (1 1/2") deep, drilled in the center of the top surface. Iron rods not less than three quarters of an inch (3/4") diameter and four feet (4') in length may be substituted in locations approved by the MassDevelopment Engineering office.

   (c) No permanent monuments shall be installed until all construction that could destroy or disturb them is completed. The tops of monuments shall be set flush with the final graded surface. Any existing monument destroyed or disturbed by any activities related to the development or use of a parcel shall be reset or replaced at it's original location. The same standards will be held for the resetting or replacement of monuments as for the placement of new monuments.
