Introduction

– Resource Description

– Laws & Regulations

– Range of potential impacts and protective measures

– Internal processes and costs

Resource description: archaeological sites• Archaeological

resources or sites: locations that contain evidence of previous human presence or activity

• Evaluating archaeological resources is an exercise in discovery

Living floor from Newberry Crater, ca. 9500 BCE

Why is ODOT involved?• Seven federal laws and three Oregon state laws

regulate the protection of archaeological resources

• It’s the right thing to do:

– Tribal relationships

– Stewardship responsibilities

National Environmental Policy Act (NEPA):• Stipulates that federally assisted undertakings

must evaluate effects to natural and cultural resources

• Culminates in preparation of an Environmental Assessment (EA) or Environmental Impact Statement (EIS)

• Allows for public and tribal involvement in decision making process.

National Historic Preservation Act (NHPA), Section 106:• Requires federally

funded undertakings to take into account effects to cultural resources, including archaeological resources

• Specifies a process and establishes criteria by which to evaluate cultural resources

Sagebrush bark sandals from Fort Rock cave, ca. 9000 BCE

Department of Transportation Act, Section 4(f):• Specifies that transportation projects should

strive to protect cultural resources

• If a feasible alternative exists where the transportation project can be constructed and avoid the cultural resource, 4(f) requires the selection of that alternative

• Only applies to archaeological sites if preservation in place is warranted

Example: Mosier Mounds Complex, Wasco Co.

Columbia River Gorge National Scenic Area Act (CRGNSA):

• Establishes specific processes for dealing with protection of cultural resources within the Gorge National Scenic Area

– Confederated Tribes of the Warm Springs– Confederated Tribes of the Umatilla– Yakama Indian Nation (Washington)– Nez Perce Tribe of Idaho

• Mandates consultation with Columbia River Treaty Tribes

ORS 97.740: Indian Graves and Protected Objects• Specifies penalties for disturbance of

Indian graves or funerary/sacred objects

• Persons disturbing such remains, including through inadvertence, must reinter at own expense, in coordination with the appropriate Tribe(s)

ORS 358.905: Archaeological Objects and Sites• Specifies that removal or

excavation of archaeological material must be authorized by a permit issued by State Parks and Recreation Department (SHPO)

ORS 390.235: Archaeological Sites and Historical Materials• Specifies that no

permit is effective without approval of state agency managing public land, and appropriate Indian Tribe(s)

Stewardship and Government-to-Government Relationships

• Coordination and positive relationships with Oregon’s Tribes are critical for success of projects involving archaeological resources

• Executive order 96-30: Tribes have legal status as independent nations, relationship is one of government to government.

• Regulations consider a resource’s information potential; prehistoric sites often possess a cultural significance for the Tribes that transcends information value.

Potential range of impacts:

• Ground disturbance:

– Staging of equipment and material

– Embankment

– Guardrail installation/flaring

– Culvert extensions, etc.

Urban archaeology:• Difficult to identify through

field survey; despite extensive disturbance, potential exists for undiscovered sites during construction

• Coordination is key: contact ODOT archaeologists if cultural material is encountered during project construction

Protective Measures: Specifications 00170.51: Protection of Cultural Sites

• Lists federal and state laws that address protection of cultural resources on the job

• Details protective measures to maintain and consequences of disturbance

• Streamlines the process for regulatory buy-off

Protective Measures: No work zones

• Cost: in most circumstances no work zones satisfy federal regulations and Tribal concerns without further cost, time

• Visibility: demonstrates ODOT’s commitment to protecting sensitive areas to Tribes and Regulators

• Assists contractor in knowing exactly where sensitive areas are on a project

• Avoids accidental disturbance to resources during project construction.

Protective Measures: No work zones

• Typically Typically extend extend from ditch from ditch line to line to right-of-right-of-way way boundaryboundary

Protective Measures: No work Protective Measures: No work zoneszones

Internal Procedures: Phase I• Consists of a search of

archaeological sites records and historic documents

• Field survey and exploratory sub-surface probing when appropriate

• Averages one month to complete, with minimal cost, ca. $4k

Internal Procedures: Phase II

• Sub-surface testing to determine boundaries, content, integrity and significance

• If sites are not significant, no further investigation is necessary; if site is significant and unavoidable, mitigation strategies must be identified (phase III)

• Phase II averages 3-6 months, and costs an average of 30k per site.

Internal Procedures: Phase III• If a significant

site is unavoidable, data recovery records and preserves information from the site

• Time-consuming and costly; development and review of data recovery plan can take 6-9 months, and fieldwork is labor and time intensive. Phase III begins at ca. 100k and can exceed 1000k.

Conclusion• Coordination early in project development

• Communication on scope changes and willingness to explore creative solutions

• Early identification, communication and protective measures help to ensure projects– avoid resource conflicts,

– obtain clearance from Tribes and Regulators

– stay on schedule
