This petition with a revised plan dated March 24, 2021, includes the proposed construction of a line of underground electric conduits and manholes, including the necessary sustaining and protecting features, under and across the public ways or ways, by National Grid, referenced in City Council Order 21.197. The installation is proposed to be located beginning at a point approximately 178 feet northeast of the centerline of the intersection of Industrial Drive and Damon Road and continuing in a northeast direction. National Grid proposes to install Manhole 1 with approximately 20 feet of four 5-inch, future use conduit to the northwest, approximately 45 feet of two 5-inch conduit to pole P7-25, approximately 377 feet of six 5-inch conduit from Manhole 1 to Manhole 2, approximately 37 feet of two 5 inch conduit from Manhole 2 to P7-50, and approximately 20 feet of four 5-inch, future use conduit to the northeast from Manhole 2, as shown on the attached plan dated March 24, 2021. No potential conflicts were observed, but the contractor shall use caution when excavating since the exact location of the existing sewer force main is unknown. A trench permit approved by the DPW has already been issued for the Damon Road project to Gagliarducci Construction who will be installing the manholes and conduit under contract with MassDOT. This permit will be revised to reflect the specifics of the above work upon approval of this petition by Council.
