Historic properties within the project have been researched and identified through field survey and background research.
Any identified adverse effects to historic properties will be avoided or minimized and mitigated where necessary.
The Oregon State Historic Preservation Office, federally-recognized tribes, project consulting parties and the general public will be consulted throughout these efforts.
In June 2019, a Historic Resource Baseline Report was completed that summarizes built environment resources in the APE. In May 2021, an in-depth analysis of resources that were identified in the Baseline Report was completed and documented in the Determinations of Eligibility.
The Area of Potential Effect (APE) is the geographic area where the project actions may result in impacts to cultural resources.
SHPO is the State Historic Preservation Office.
THPO is the Tribal Historic Preservation Office.
NHO is the Native Hawaiian Organization.
ACHP is the Advisory Council on Historic Preservation.
To identify eligible historic and archaeological resources, we:
The term “effect” is defined under 36 CFR §800.16(i) as an “alteration to the characteristics of historic property qualifying it for inclusion in, or eligibility for the National Register.” The project’s impact on the property’s use, character, location, and setting are considered when determining its effect on the historic property. An effect is considered adverse under 36 CFR §800.5(a)(1) when it will endanger those qualities that make the property eligible for inclusion in the National Register. Adverse effects of a project can be direct or indirect. Typical examples include:
For additional information, visit the Advisory Council on Historic Preservation's webpage on the Section 106 process.
Three historic resources that are potentially eligible for listing in the National Register of Historic Places may be impacted by the project.
One archaeological resource identified is NRHP-eligible and will be impacted by the project.
We are currently evaluating the potential alternatives to avoid adverse effects to the identified significant resources.
We have prepared draft Section 106 Finding of Effect documents assessing the adverse effects. We are currently working with our Section 106 consulting parties to finalize the documents and share for public review.
We will continue consultations to mitigate the proposed adverse effects as part of the Section 106 process. This summer, we will conduct additional public outreach to gather input as we develop measures to mitigate for adverse effects.
