INTRODUCTION Tierra was contracted by Wetland Resources to conduct a cultural resources assessment for the Soundview Business Campus Project (the project), located in Section 3, Township 28 North, Range 4 East, Willamette Meridian, in Everett, Snohomish County, Washington. The project proposes to divide approximately 39 acres into 5 lots of 4 buildings and a paved area containing 650 parking stalls on Snohomish County Tax Parcel 28040300200100 (Figures 1-3). The project also includes the filling of four wetlands. Mitigation of wetland filling will through use of an off -site mitigation bank. This report has been prepared to assess the effects of the project on cultural resources, in accordance with Section 106 of the National Historic Preservation Act of 1966 (NHPA), as amended. PROJECT INFORMATION Facility Construction The project proposes to construct four buildings and parking lots and install utilities, storm water systems, and a central access road from 36`h Avenue NE. Work associated with the building facilities and roadway would be within the central portion of the site. Project development would require clearing, grading, and grubbing, which would necessitate the removal of trees and heavy undergrowth within the proposed footprint. Tierra understands the APE to be defined as the footprint of construction as described above and illustrated in Figures 1-5. Staging areas are to be located within the APE. REGULATORY CONTEXT National Historic Preservation Act Under Section 106 of the NHPA, agencies involved in a Federal undertaking must take into account the undertaking's potential effects to historic properties (36 CFR 800.16(l)(1)).The project will require a permit from the U.S. Army Corps of Engineers (USACE), a Federal agency, and therefore the project is considered a Federal undertaking. The work performed by Tierra was intended, in part, to assist in regulatory requirements for Section 106 of the NHPA and the implementing regulations in 36 Code of Federal Regulations (CFR) Part 800. A historic property is typically aged 50 years or older and is defined in 36 CFR Part 800.16(1)(1) as follows: ... any prehistoric or historic district, site, building, structure, or object included in, or eligible for inclusion in, the NRHP maintained by the Secretary of the Interior. This term includes artifacts, records, and remains that are related to and located within such properties. The term includes properties of traditional religious and cultural importance to an Indian tribe or Native Hawaiian organization and that meet the National Register criteria. The procedures under Section 106 generally require the Federal agency involved in the undertaking to identify the APE, inventory any historic properties that may be located within the APE, and determine if the identified historic properties located within the APE may be eligible to be listed in or eligible for listing in the NRHP. An APE is defined in 36 CFR 800.16(d), as follows: Tierra Archaeological Report No. 2014-077 2
