OR 219: Hillsboro to Silverton Highway @ Wilsonville Road
Yamhill County, Oregon
Key No. 09274, File Type E Report Prepared By: Alex McMurry, ODOT Cultural Resources Specialist, January 2004
Report Reviewed By: Rosalind Keeney, ODOT Cultural Resources Team Leader
The area surveyed for the OR 219: Hillsboro to Silverton Highway @ Wilsonville Road contains two historic resources, one of which (Map ID#1: 1200 S Springbrook Road) may be potentially eligible for listing on the National Register of Historic Places. If this resource is determined to be potentially eligible through further research and documentation, project designs should be developed that avoid the resource if possible. If this property is impacted (either directly or indirectly) the project’s effects to this resource shall be determined as per the guidance established in Section 106 of the National Historic Preservation Act of 1966 and Section 4(f) of the Department of Transportation Act. It is anticipated that the resource will be determined potentially eligible for the National Register at the time of this writing.
High crash rates at the intersection of Wilsonville Road and OR 219 necessitate safety improvements for this intersection, which has been a top 10% SPIS site for a number of years. The problems stem from high traffic speeds on OR 219, excessive delays on the side street, and numerous conflict points in the immediate area. The safety issues at this intersection will be resolved by disconnecting Wilsonville Road from OR 219 and building a new alignment that will connect Wilsonville Road to OR 219 approximately 300 feet north of the current intersection. Traffic will be routed along Springbrook Road to the proposed intersection location, which will have a traffic signal installed. OR 219 will be widened near the proposed intersection to accommodate a single left turn refuge for traffic turning onto Wilsonville Road from OR 219.
In addition to the intersection realignment at Wilsonville Road, access from Sandoz Road and Adolf Road will be changed as a part of the project. The intersection of Adolf Road with OR 219 may be closed or redesigned as a part of the project, and turning movements between OR 219 and Sandoz Road will be limited to right turn only from OR 219 onto Sandoz Road and right turn only from Sandoz Road onto OR 219.
The proposed realignment of Wilsonville Road will pass through an open park space just south of an electrical substation (see attached aerial photo for current alignment proposal).
Definition of Area of Potential Effect (APE)
For Section 106 purposes, the Area of Potential Effect (APE) is roughly defined as the project’s Area of Potential Impact, which includes the existing ODOT right of way along OR 219 near its intersection with Wilsonville Road. The APE also includes tax lots bordering Springbrook Road and Wilsonville Road near the proposed intersection improvement and tax lots bordering the ODOT right of way along OR 219 in the area of the proposed intersection and left turn refuge. See below for a map of the APE.
Map of Area of Potential Effect (APE)
Methods used to identify newly-discovered or previously documented historic resources in the Area of Potential Effect included a reconnaissance level survey of the APE and a review of the Yamhill County Cultural and Historic Resources Inventory at the Oregon State Historic Preservation Office. During the field (reconnaissance) survey, resources that appeared to be 45 years of age or older were photographed and inventoried, and are the subject of this report. Properties within the APE shown on the map above that were identified during the field survey are shown on Table 1: Historic Resources Identified.
Literature Search: The review of the City of Newberg and Yamhill County Cultural and Historic Resources Inventories and State Historic Preservation Office (SHPO) database resulted in the finding of one resource within the project area that has been previously documented at SHPO. This resource is the house and barn located at 1200 S Springbrook Road, identified in this report as Map ID#1 (SHPO #1636, Yamhill County).
Field Survey: A reconnaissance level field survey was conducted on January 13, 2004 by Alex McMurry, ODOT Cultural Resources Specialist. The on-site survey was undertaken to verify the presence of cultural, architectural, and engineering resources that appear to be 45 years old or older. Resources that meet this age were photographed and a cursory level of information was compiled for each resource, including property name, address, approximate construction date, stylistic influence or resource type, and tax lot number. A preliminary analysis of National Register eligibility was also made for the identified resources. The results of the on-site survey are given in the attached Table 1: Historic Resources Identified. Resources identified during the field survey are located on the attached Historic Resource Location Map.
The reconnaissance level survey resulted in the determination that one resource within the project APE may be potentially eligible for listing on the National Register of Historic Places. Further research is necessary to make a definitive Determination of Eligibility for this resource, the house and barn located at 1200 S Springbrook Road. This resource is considered to retain sufficient integrity and to be of sufficient age to be considered potentially eligible for listing on the National Register of Historic Places. This resource will require preparation of a Section 106 Determination of Eligibility to ascertain the historic significance and material integrity of the resource.
In conclusion, there is one historic resource (Map ID#1: 1200 S Springbrook Road) in the project Area of Potential Effect (APE) that may be potentially eligible for listing on the National Register of Historic Places. This property will require research and documentation for compliance with Section 106 of the National Historic Preservation Act. Project impacts to this historic resource will also be assessed according to the guidance established in Section 106 and Section 4(f) of the Department of Transportation Act.
