APPENDIX A

CULVERT RESOURCE INVENTORY TABLE

RESOURCE INVENTORY TABLE The following six pages present a table of data pertaining to the 98 culverts inventoried in the field survey portion of this study. The resources are listed alphabetically first by county name and then by town name. The other column headings and abbreviations used in the table are as follows: NHDHR #: This is the individual inventory number assigned by the New Hampshire Division of Historical Resources for each historic resource in a town. Type: This refers to the type of culvert, box culvert (B), arch culvert (A), pipe culvert (P), or wood (W). Work: This refers to the predominate type of stone masonry work used in the construction of the culvert, either fieldstone (F), or Ashlar (A). These terms were loosely defined for the purposes of speeding the fieldwork: fieldstone meaning of local uncut or roughly hammer split or shaped stone; Ashlar meaning cut stone, either quarry split and squared – the usual case of lintels or local stone fully squared-up with hammer and chisel or otherwise split and cut to provide multiple flat faces. In the case of pipe culverts with stone facewalls that lack integrity, the stone work was considered uninterruptable and therefore not applicable (n/a). Span ft.: This refers to the distance in feet between the culvert channel walls, also called the width of the waterway. It is the unsupported span of the lintels or slabs that form the ceiling of the culvert, or the distance between the spring points of an arch. Lgt. ft.: This refers to the distance in feet between the culvert inlet and outlet facewalls, also called the length of the waterway or length of the channel walls. Cells: This refers to the number of separate culvert channels, also known as cells or barrels. A double box culvert, for example, has two cells. Altered: This refers to whether the culvert shows evidence of being altered in some way – yes (Y) or no (N). Refer to the corresponding notes (on table pages 4-6) for explanation. NR: This refers to the potential eligibility of the culvert for listing in the National Register of Historic Places: yes (Y), likely eligible, or no (N), not likely eligible. The assessment is the opinion of the project architectural historian only.

SECRETARY OF THE INTERIOR'S STANDARDS FOR THE TREATMENT OF

HISTORIC PROPERTIES

NOTES REGARDING APPENDICES D, E AND F: Appendix D: The "Secretary's Standards" contained in this section were first developed in 1978, edited in 1983 and again in 1992 in the present form. They became federal law in 1995 (36CFR68). They are regulatory only for projects receiving federal grant-in-aid funds, but are the accepted standards recommended for the treatment of all historic properties. Appendix E: Because the Secretary's Standards were written to apply to buildings, the Virginia Transportation Research Council modified the language of the Standards to better meet the needs of historic bridges by creating the Guidelines for the Treatment of Historic Bridges. These are presented since no guidelines exist for historic culverts. Appendix F: Secretary of the Interior's Standards for Rehabilitation – Building Masonry are more specific standards for the treatment of individual building elements. Although directed at the masonry of buildings, the recommendations are generally applicable to the treatment of stone culverts.
