Process through which cultural resources are made known.
IDT - Interdisciplinary Team
The likely effects of an action or proposed action upon specific natural, cultural, or socioeconomic resources. Impacts may be direct, indirect, cumulative, beneficial, or adverse. Severe impacts that harm the integrity of park resources or values are known as "impairments."
An impact so severe that, in the professional judgment of a responsible National Park Service manager, it would harm the integrity of park resources or values and violate the 1916 National Park Service Organic Act.
A plan that tiers off the General Management Plan (GMP) and tells how to accomplish one of more of the desired resource conditions or visitor experiences. Implementation plans can be specific resource protection plans or plans like construction documents.
Incremental Treatment (Historic Structure Report (HSR))
Treatment of a structure may be phased over several years or funding cycles. It is possible to realize the ultimate treatment over time by addressing a structure's components incrementally. For example, restoring the roof one year and reconstructing shutters the following year. Addressing one feature such as window rehabilitation or one management issue such as universal accessibility requires a clear understanding of the entire structure. Except for preservation, at minimum, a comprehensive Part 1 of an HSR and a feature- or project-specific Part 2 should be completed prior to any incremental treatment. Ultimate treatment, or the desired final effect, must be identified prior to conducting any phased or incremental treatments.
A contract that may be used to acquire supplies and/or services when the exact times and/or exact quantities of future deliveries are not known at the time of contract award. There are three types: definite quantity; requirements; and indefinite quantity. (FAR 16.501-2(a) - Federal Acquisition Regulation)
An indefinite-delivery contract that provides for an indefinite quantity, within stated limits (minimum and maximum), of supplies or services to be furnished during a fixed period, with deliveries or performance to be scheduled by placing orders with the contractor. (FAR 16.504(a) - Federal Acquisition Regulation)
Any person who is a member of any Indian tribe, band, group, pueblo, or community which is recognized by the Federal Government as eligible for services from the Bureau of Indian Affairs (BIA) and any Native as defined in the Alaska Native Claims Settlement Act. (FAR 26.101 - Federal Acquisition Regulation)
The governing body of any Indian tribe or entity established or recognized by the governing body of an Indian tribe. (FAR 26.101 - Federal Acquisition Regulation)
Any Indian tribe, band, pueblo, or community, including native villages and native groups (including corporations organized by Kenai, Juneau, Sitka, and Kodiak) as defined in the Alaska Native Claims Settlement Act, which is recognized by the Federal Government as eligible for services from Bureau of Indian Affairs (BIA). (FAR 26.101 - Federal Acquisition Regulation)
Inherently Governmental Function
A function that is so intimately related to the public interest as to mandate performance by the Government. Such functions include activities that require either the exercise of discretion in applying Government authority (i.e., the act of governing) or the making of value judgments related to Government monetary transactions and entitlements. (FAR 7.501 - Federal Acquisition Regulation)
The replacement of historic fabric with new material that marches the historic detail, configuration, appearance and fabric as closely as humanly possible.
Examining and testing supplies or services (including, when appropriate, raw materials, components, and intermediate assemblies) to determine whether they conform to contract requirements. (FAR 46.101 - Federal Acquisition Regulation)
Integrated Design Narrative
This narrative shall identify opportunities for integration of design showing trade-offs between different aspects of the design particularly between disciplines, with explanations for how these trade-offs were made. Examples include:
- Adapting building orientation to reduce energy use.
- Adapting siting to enhance daylighting.
- Adapting building envelope design to accommodate the use of locally available materials, etc.
The narrative should be the product of the design team. The structure of the design narrative shall be organized around Guiding Principles for Federal Leadership in High Performance and Sustainable Buildings set forth in the Federal Leadership in High Performance and Sustainable Buildings Memorandum of Understanding (2006). The five guiding principles of sustainability in this document are:
- Employ Integrated Design Practices
- Optimize Energy Performance
- Protect and Conserve Water
- Enhance Indoor Environmental Quality
- Reduce Environmental Impact of Materials
Special attention shall be paid to complying with sustainability requirements in an integrated way. Building design and siting should enhance the performance of the project.
Integrated Pest Management (IPM)
A decision-making process that coordinates knowledge of pest biology, the environment, and available technology to prevent unacceptable levels of pest damage, by cost-effective means, while posing the least possible hazard to people, resources, and the environment.
The authenticity of a property's historic identity, evidenced by the survival of physical characteristics that existed during its historic or prehistoric period; the extent to which a property retains its historic appearance.
Intelligent Transportation System (ITS)
Systems that utilize electronics, communications and information processing to improve the efficiency and safety of surface transportation. See Intelligent Transportation Systems Joint Program Office.
Interdisciplinary Team (IDT)
Project team that includes designers (architects, engineers, landscape architects), planners, resource/compliance specialists, editors, visual information specialists, and resource specialists; IDT may be composed of any combination of National Park Service park, regional, and/or Denver Service Center employees and Architect/Engineers or other private enterprise employees.
- A prime contractor or an actual or prospective offeror whose direct economic interest would be affected by the award of a subcontract or by the failure to award a subcontract. (FAR 26.101 - Federal Acquisition Regulation)
- For the purpose of filing a protest, an actual or prospective offeror whose direct economic interest would be affected by the award of a contract or by the failure to award a contract. (FAR 33.101)
A mode is a particular form of transportation, such as automobile, transit, carpool, ship, bicycle. Intermodal refers to connections between modes.
Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA)
This landmark $155 billion federal legislation signed into law in December 1991, called for broad changes in transportation decision-making, and included major revisions to metropolitan and statewide planning processes. ISTEA emphasized diversity and balance of modes, as well as the preservation of existing systems over construction of new facilities. The law expired in September 1997, and was followed by the Transportation Equity Act for the 21st Century (TEA-21), which was superseded by the the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) in August 2005.
Communication of the historic and cultural values of a historic structure to a visitor through a variety of media.
Interpretive Prospectus (IP)
Identifies specific interpretive themes and objectives. It contains recommendations on appropriate media for interpretive exhibits.
Introduction (Cultural Landscape Report (CLR))
The introduction includes five sub-sections:
- management summary describing the purpose of the project
- historical overview that provides a brief historical context for the landscape
- description of the scope of the project and methodology for completing it
- description of study boundaries
- summary of findings
