Federal, state and local statutes may require environmental assessments prior to development. Landmark Archaeological & Environmental Services locates and identifies archaeological/cultural resources within your project area or potential project area.

Throughout the entire archaeological assessment process, Landmark personnel work with you to (1) ensure proper compliance with State and Federal regulations, (2) make efficient use of your time and money, and (3) produce quality work within your work schedule. Landmark understands that keeping you informed is part of our job... and we prefer it that way.

As part of the environmental assessment process, we can provide the following services:

  • Project region overviews (Overviews)


  • Literature and site file checks (Records checks)
    • Research of an individual project area that indicates the presence or absence of previously recorded archaeological sites, and or the potential for discovery of additional cultural resources.

  • Archaeological survey (Phase I a)
    • Systematic investigation of a project area to identify archaeological sites.

  • Archaeological survey (Phase I b)
    • A more intensive and focused systematic investigation of a project area to make assessment of specific areas, and to guide Phase II testing.

  • Archaeological survey (Phase I c)
    • Systematic investigation of deep and well-drained alluvial soils to locate buried archaeological sites and features.

  • Archaeological site testing (Phase II)
    • Sampling of a potentially significant archaeological site to determine the presence of intact sub-surface deposits and evaluation of site's eligibility for nomination to the National Register of Historic Places.

  • Archaeological mitigation (Phase III)
    • Extensive and intensive sampling of a significant archaeological site aimed at reasonable data recovery in order to mitigate adverse effects of proposed federal and state undertakings.

      Fieldwork may include archaeological monitoring of disturbances in sensitive areas.

      Recordation and documentation: detailed reports with full recommendations are submitted at the completion of each phase of investigation described above.

We understand the need for haste in most cases, and take this into consideration as your work is scheduled. Fieldwork is carried out year-round, using heated shelters if and where possible. The weather may not be flexible...but we are.

Clients receive a comprehensive report that states our chosen procedures, results, and recommendations. This report is also filed at the Indiana Department of Natural Resources, Division of Historic Preservation and Archaeology (IDNR, DHPA), providing a reference for future archaeological resource assessments.

National Register Nomination

The National Register of Historic Places (NRHP), administered by the Department of the Interior and the National Park Service, is the Nation's official list of cultural resources that have been determined worthy of preservation. Landmark personnel have been involved in preparing numerous National Register nominations including "districts, sites, buildings, structures, and objects that are significant in American history, architecture, archaeology, engineering, and culture" as provided for by the NRHP nomination form criteria.

National Landmark Nomination

Landmark can assist with documentation and nomination of culturally significant properties with the National Historic Landmarks program.

Historic Structure Surveys

Landmark Archaeological and Environmental Services may be called upon to identify and document historically or architecturally significant structures within a given project area. These assessments are made by assembling descriptions that include historical documents, maps, blueprints and photographs depicting structures and landscapes. Determination of eligibility and nomination to the National Register of Historic Places (NRHP) may also be accomplished as a part of this evaluation process.
