Project Area Forms

Lake Sunapee Power Company

This project examined historic resources associated with the Lake Sunapee Power Company located along 2.8 miles of the Sugar River in Sunapee, NH.   The remaining discontiguous resources included two dams and two powerhouses.  These resources related to an era of expansion in the New Hampshire electric industry and the post-WWI “white coal” (i.e., hydroelectric) boom in the state.    Although the Lake Sunapee Power Company buildings and structures once strongly demonstrated these themes, due to the lack of integrity of the remaining structures and the loss of critical elements of the original design the discontiguous resources did not together meet the requirements for listing on the National Register.

Souhegan Falls Water-Powered Industry Area

This 2018 project area form was completed in connection with a planned multi-use path along the Souhegan River in Merrimack.  One potential route  for the path  traveled under U.S. Route 3, making use of an existing  canal and other structures that had carried water from a dam on the west side of Route 3 to industries on the east side of the road.   The project area form assessed the remaining fragments of the water-powered industry in the area (consisting of the largely archeological remains of a tannery) and the remaining structures associated with a former dam at Souhegan Falls (canal, headgate, forebay  etc.). 

Sagamore Avenue Project Area 2014

This project area form was prepared in connection with a City of Portsmouth improvement project along a roughly one mile stretch of Sagamore Avenue; it was one of a number of projects that Preservation Company has completed in the area. The form identified the area’s primary historical context as suburban/bedroom community growth, with the major period of development beginning in the early twentieth century after the arrival of the electric railway in 1899. The form recommended in-depth documentation of both the South Cemeteries and a group of houses located on Sagamore Avenue between South Street and Jones Avenue, which could potentially be a component of a larger historic district.

Berlin’s Historic Neighborhoods
