I-5 JBLM Vicinity Congestion Relief Project, South Study Area: Supplemental Environmental Assessment and Online Public Meeting – Archaeological and Historic Resources

Projects that receive federal funding or are subject to federal approval must comply with Section 106 of the National Historic Preservation Act (NHPA) of 1966. This Act requires federal agencies to evaluate the effects of federally funded or permitted projects on historic properties and consult with stakeholders to avoid, minimize, or mitigate adverse effects.

JBLM was first established as Camp Lewis in 1917 and several of the earliest buildings are still standing.  The Fort Lewis Garrison Historic District (Historic District), located immediately adjacent to I-5 north of Exit 119, is eligible to be on the National Register of Historic Places (NRHP) and is listed on the Washington Heritage Register. The Red Cross Hostess House (Family Resource Center), Red Cross Field Office and the Red Shield Inn/Lewis Army Museum are unique historic structures located on JBLM adjacent to I-5.  The Red Cross Hostess House and Field Office buildings are NRHP eligible and the Red Shield Inn is listed on the NRHP.

The project would permanently affect 3.8 acres of the 494-acre Historic District and temporarily affect an additional 2.1 acres. These impacts are unavoidable because the western edge of the Historic District touches the edge of northbound I-5 where the widening would take place.  Several design features are planned to minimize impacts to the Historic District including slightly narrower travel lanes on I-5, a compact interchange configuration, retaining walls instead of fill slopes, and all stormwater facilities located outside the historic district.

No historic buildings would be adversely impacted by the project. Due to the minimal amount of land affected, the project would not diminish the significance or integrity of the historic district or buildings on JBLM. The project would not adversely affect historic resources.
