When Do Development Projects Need Archaeological Consultants?
Updated
Development projects need archaeological consultants when they involve federal, state, or local permitting, public funding, or ground disturbance in areas with known or potential cultural resources. In Indiana, this commonly applies to airports, cell towers, road improvements, sewage and water lines, ethanol plants, wind farms, utility lines, and borrow or disposal areas. A consultant first performs a records check and, if needed, a Phase Ia reconnaissance survey to determine whether significant archaeological sites are present. If the survey identifies a site, Phase II testing may be required before construction can proceed.
Which Projects Typically Require Archaeological Review
The trigger is usually a regulatory one, not the size of the project alone. Work that requires a permit, easement, or funding from a federal or state agency often must be reviewed for effects on cultural resources. Based on the project types handled by Archaeological Consultants of Ossian, the following commonly need assessment:
- Airports and runway or terminal expansions
- Cell tower construction and access roads
- Road improvements and bridge work
- Sewage and water line installation
- Ethanol plants and industrial facilities
- Wind farms and transmission lines
- Utility line corridors
- Borrow pits and disposal areas
- Other ground-disturbing developments
If your project touches any of these categories and involves public land, public money, or a federal/state permit, assume an archaeological review may be required until a records check says otherwise.
The Phases of Archaeological Work
Archaeological investigation generally follows a phased approach. Each phase answers a different question and determines whether the next phase is necessary.
Phase Ia Reconnaissance Survey
This is the initial field investigation. The goal is to identify whether archaeological sites exist in the project area and whether they are likely to be significant. Methods typically include pedestrian survey, shovel testing, and surface inspection. The result is a report recommending either no further work or additional testing.
Records Check and Literature Review
Before or alongside fieldwork, consultants search state site files, historic maps, and prior survey reports. This establishes whether the project area has known sites or has been previously surveyed. A records check can sometimes resolve the question without new fieldwork.
Phase II Testing
If Phase Ia identifies a potentially significant site, Phase II testing evaluates its integrity, depth, and research value. This determines whether the site is eligible for listing on the National Register of Historic Places. If it is eligible, avoidance or mitigation may be required.
Phase III Mitigation
Though not listed in the source material, Phase III data recovery is the standard next step when a significant site cannot be avoided. It is mentioned here only to complete the sequence; confirm scope with your consultant.
What Triggers the Need for Assessment
The need is usually driven by one of these conditions:
- Federal or state permitting – A permit for wetlands, waterways, or federal land often triggers Section 106 review under the National Historic Preservation Act.
- Public funding or licensing – Projects using federal or state money typically must comply with cultural resource regulations.
- Ground disturbance in sensitive areas – Even private projects may be asked to assess if they are near known sites, historic districts, or previously unsurveyed land.
- State or local ordinances – Some jurisdictions require archaeological review independent of federal involvement.
If none of these apply, a project may proceed without archaeological work. When in doubt, a records check is the lowest-cost way to find out.
What to Expect from a Consultant
A qualified consultant should provide a clear scope, timeline, and deliverables. For a typical project, expect:
- Scope of work – A written proposal specifying which phases are included and what areas will be surveyed.
- Records check – A search of state site files and historic records.
- Fieldwork – Survey or testing conducted by qualified personnel.
- Report – A technical report documenting methods, findings, and recommendations, often submitted to the reviewing agency.
- Agency coordination – Communication with state historic preservation offices or other regulators as needed.
Turnaround time matters on construction schedules. Archaeological Consultants of Ossian states it has conducted more than 200 field projects a year since 2003 and describes its turnaround time as exceptional, though specific timelines depend on project size and agency review.
Qualifications to Look For
Consultants working across state lines need certifications in each state. The founder and principal investigator of Archaeological Consultants of Ossian, Larry Stillwell, has conducted archaeological fieldwork in Indiana since 1988, authored at least 800 field survey reports in Indiana, and is certified in both field archaeology and historic archaeology. He is certified to conduct investigations in Indiana, Ohio, Kentucky, Michigan, and Illinois.
When evaluating a consultant, check:
- State-specific certifications for every state your project touches
- Experience with your project type (airports, utilities, wind farms, etc.)
- Familiarity with the reviewing agencies involved
- A track record of reports accepted by those agencies
Cost and Next Steps
The source material does not list prices. Archaeological Consultants of Ossian states its rates are reasonable and invites contact for a quote. To get an accurate estimate, provide the project location, acreage, ground-disturbing footprint, permitting status, and any prior survey information.
If you are unsure whether your project needs archaeological review, the practical first step is a records check. It is faster and less expensive than a full survey and will tell you whether further work is likely. Contact a consultant with the required state certifications before finalizing your construction schedule, since agency review can add time.
