The College Avenue project entails reconstruction of the roadway as a two lane road with a center turn lane in certain locations, left turn lanes at some intersections, and wetland/riparian enhancement and culvert replacement along Garrison Creek. Along Rose Street, the reconstruction includes a two lane road with a center turn lane. The project also includes sidewalks on both sides of College Avenue, and a multi‐use path on the south side of Rose Street. Additional improvements include street lighting and landscaping, and may include replacement or new installation of water, sewer, and storm water utilities. The project is being funded by the Federal Highway Administration. As this is a federally funded project, the potential impacts to historic properties must be considered prior to implementation, as per Section 106 of the National Historic Preservation Act.
The background research identified eight previously recorded archeological sites and two National Register of Historic Places properties within 1.0 mile (1.6 kilometer) of the proposed undertaking. There are 26 structures included on the Department of Archaeology and Historic Preservation’s Historic Properties Inventory that lie adjacent to the project boundaries. Cartographic and historic references indicate that the project area lies within an area active with development as early as the 1870s.
Plateau conducted cultural resources survey, a review of potential historic properties along the route, and monitored geotechnical investigations for the project. No Native American or historic era cultural materials or features were identified during the cultural resource survey of the proposed road reconstruction project. The proposed undertaking will result in No Historic Properties Affected, and no further archaeological investigations are recommended prior to, or during, execution of this project.
