STATE HISTORIC BRIDGE INVENTORY AND EVALUATION 2024 UPDATE The National Register Bulletin "How to Apply the National Register Criteria for Evaluation" (National Park Service 1997) describes the aspects of integrity and their relevance to the NRHP Criteria for Evaluation. The seven aspects of integrity are explained in the bulletin as follows: Location is the place where the historic property was constructed or the place where the historic event occurred. The relationship between the property and its location is often important to understanding why the property was created or why something happened. The actual location of a historic property, complemented by its setting, is particularly important in recapturing the sense of historic events and persons. Design is the combination of elements that create the form, plan, space, structure, and style of a property. It results from conscious decisions made during the original conception and planning of a property(or its significant alteration) and applies to activities as diverse as community planning, engineering, architecture, and landscape architecture. Design includes such elements as organization of space, proportion, scale, technology, ornamentation, and materials. A property's design reflects historic functions and technologies as well as aesthetics. It includes such considerations as the structural system; massing; arrangement of spaces; pattern of fenestration;textures and colors of surface materials;type, amount, and style of ornamental detailing; and arrangement and type of plantings in a designed landscape. Design can also apply to districts, whether they are important primarily for historic association, architectural value, information potential, or a combination thereof. For districts, significant primarily for historic association or architectural value, design concerns more than just the individual buildings or structures located within the boundaries. It also applies to the way in which buildings, sites, or structures are related. The bridges along the Hamakua Coast on the Island of Hawaii demonstrate this aspect of integrity through their innovative and unique construction involving repurposing of former railroad trestles. Setting is the physical environment of a historic property. Whereas location refers to the specific place where a property was built or an event occurred, setting refers to the character of the place in which the property played its historical role. It involves how, not just where, the property is situated and its relationship to surrounding features and open space. Setting often reflects the basic physical conditions under which a property was built and the functions it was intended to serve. In addition, the way in which a property is positioned in its environment can reflect the designer's concept of nature and aesthetic preferences. The physical features that constitute the setting of a historic property can be either natural or manmade, including such elements as:topographic features (a gorge or the crest of a hill); vegetation; simple manmade features (paths or fences); and relationships between buildings and other features or open space. These features and their relationships should be examined not only within the exact boundaries of the property, but also between the property and its surroundings. This is particularly important for districts, such as the Hana Belt Road, where the road's historic bridges conform to the topography and blend with the lush surroundings. Materials are the physical elements that were combined or deposited during a particular period of time and in a particular pattern or configuration to form a historic property. The choice and combination of materials reveal the preferences of those who created the property and indicate o¢��= 4
