Cultural Resources

Clients throughout the country rely on our cultural resource team to provide timely, cost-effective, and accurate investigations for National Historic Preservation Act (NHPA) Sections 106 and 110 compliance ensuring smooth coordination with federal and state regulatory agencies.

Historical resources are rapidly disappearing, and when removed, can never be restored.

Investigating history, architecture, archaeology, and culture provides agencies, engineers, communities, and developers an opportunity to engage the past and facilitate understanding of our shared past and present. From initial desktop survey to advanced excavations and documentation, Impact7G provides detailed, quality historic preservation studies that meet or exceed Federal, State, and local requirements that enrich the knowledge of our past while reinforcing a sense of place and identity in our communities.

Case Study: Historic Context & Evaluations of Low Head Dams

Impact7G evaluated 131 dams across Iowa, developed historic contexts at a statewide level, and created methods for researching and determining significance for dams in the Midwest.

Phase IA, I, & II Archaeological Investigations

We conduct archaeological investigations to meet your specific project needs, from an initial desktop assessment to advanced excavations and documentation. A Phase IA assessment provides information on archaeological sensitivity determining the potential for intact archaeological resources present in an area.

A Phase I intensive survey is completed to identify all archaeological sites within the project area through field examination. During a Phase II survey, an intensive site examination is conducted on targeted sites previously identified through controlled testing to collect sufficient data for National Register eligibility determinations. Our team of experts will work closely with project managers during all steps of an archaeological investigation to facilitate the entire process seamlessly.

Geoarchaeological Investigations

We also offer advanced expertise in geoarchaeological modeling and documentation to facilitate project decisions over a large geographical area. Use of geoarchaeological investigations aids in determining where and how deep potential archaeological sites can occur. Our team commonly examines large swaths of land using mixed geomorphological analysis through landscape/soil analysis, archival research, and subsurface testing. We provide clients with GIS-based files and images for accurate documentation needed for the Section 106 process. Detailed geoarchaeological analysis often leads to lowered costs associated with advanced stages of archaeological research.

Architectural History Surveys & Documentation

Prior to construction or development projects, Impact7G is commonly tasked with identifying architectural properties to evaluate their potential eligibility for the National Register Historic Places. Our team utilizes historic data sources, specialized knowledge of architectural history, historic maps, and other sources for determining property significance. Impact7G can undertake these evaluations on single buildings as well as large-scale surveys involving hundreds of potentially affected properties. Impact7G also has experience with advanced architectural documentation projects meeting all standards for mitigation of adverse effects.

Historic Property Research & Documentation

Considering effects to historic properties before destruction provides nearly everyone, from school children to professional researchers, information needed to inspire community involvement and conservation of our shared history. Thorough historic resource documentation provides State and Federal agencies data necessary for informed decisions while providing clients smooth navigation of regulatory processes, resulting in fewer project delays, greater knowledge of our past, and preservation of some of our most cherished resources.

Impact7G will be an extension of your team at all times.
