National Register Nomination
Portsmouth Downtown Historic District – Review Process for the Nomination Form
The replacement of the Memorial Bridge in downtown Portsmouth was a federally funded project that required mitigation for the loss of a nationally significant resource individually eligible for the National Register of Historic Places as well as a contributing resources to a National Register eligible downtown historic district. One of the mitigation stipulations for this project was a National Register of Historic Places nomination for the Portsmouth downtown historic district. The NH Division of Historic Resources (DHR) in partnership with the NH Department of Transportation and Federal Highways oversaw the preparation of the nomination for the district with boundaries and mapping that conforms to National Park Service Guidelines.
By law, the DHR is required to notify property owners no more than 75 days but no less than 30 days of the intent to nominate a property or district and give opportunity to comment or object to the listing. Notification must be also be sent to city and county officials. For individual properties and smaller districts, notification must be by letter. With a district as large as Portsmouth, DHR was able to publish a notification in the paper or send out individual letters. They have opted to do both. Included is a copy of the letter sent out to property owners as well as the letter that was sent to the City of Portsmouth City Council with the city's planning board, conservation commission, and historic district commission copied on that letter.
Also included is a handout on frequently asked questions about the National Register program. The information is also available on the state website by going to http://www.nh.gov/nhdhr/programs/national_register.html
Historic District Commission Design Review Tools
DESIGN GUIDELINES FOR PORTSMOUTH'S HISTORIC DISTRICT
Over the past year, the Historic District Commission (HDC) has been working with Dominique Hawkins at Preservation Design Partnership (PDP) to develop a detailed set of Design Guidelines for the nearly 1,300 properties located within in Portsmouth's Historic District.
The Guidelines are intended to be a design review tool to help manage change and protect the City's architectural and historic resources. The Guidelines provide background information, guidance and regulations to be followed by property owners, design professionals, contractors, the HDC, the Planning Staff and other City officials with regard to historic resources. They are intended as a supplement to, rather than as a substitute for, consultation with qualified architects, contractors, staff or Commission members.
Given the Commission will use the Guidelines in their decision-making process, the chapters have been carefully reviewed by the Commission and the public in advance of finalizing the overall document. The Commission intends to place the final Guidelines on the April 13th, 2016 agenda for approval and submittal to the City Council in March.
The following chapters are available for review and comment.
