Compliance
Preservation Company has vast experience working with clients to meet the requirements of Section 106 of the National Historic Preservation Act (NHPA) of 1966. We frequently work with NHDOT and NHDES on permitting for transportation enhancements, bridge rehabilitation or replacements, utilities, cell tower or antenna installations, and other federally or state-funded or licensed projects.
For most projects, Preservation Company prepares a combination of constraints mapping and reports including NHDHR Request for Project Review and Architectural Survey Plans, resource evaluations (determinations of National Register eligibility) and analyses of impacts and effects, in compliance with 106 and 4(f) regulations, according to standards specified by the NHSHPO.

As part of a project for planned improvements along Route 2 by NHDOT, Preservation Company updated the previously surveyed Jefferson Highlands Historic District as well as several individual properties. New survey was needed for five individual properties. Preservation Company then completed evaluations of effects for each National Register-eligible property and district within the Project Area.

Preservation Company completed a NHDHR Project Area Form for the thirteen-mile-long, one-mile-wide corridor of a proposed transmission line in Madbury, Durham, Newington, and Portsmouth for Eversource Energy. The installation of new utility poles required an assessment of potential visual effects for the area, which was then to the New Hampshire Site Evaluation Committee in winter of 2016. Preservation Company prepared Inventory and Historic District Area Forms for potentially affected properties and historic districts. Mitigation for Adverse Effects included a Historic American Engineering Record (HAER) documentation of the Durham Cable Terminal House before the relocation and restoration of the structure. Additionally, Preservation Company worked with BaileyDonovan to design interpretive panels and exhibit displays about the Underwater Cable Line and Terminal Houses, as well a booklet about farming in Newington. The project preservation team received an award from the New Hampshire Preservation Alliance in 2021.
