The City of Sprague is proposing to refurbish a wastewater lift station and to construct an additional wastewater lift station. The existing lift station is located near First Street, immediately east of State Route 23. The proposed lift station will be installed at the southern end of the city, near South Dayton Street. Plateau was retained to help identify potential archaeological resources and potential historic properties in the project area prior to planned ground-disturbing activities.
Prefield research revealed nine archaeological resources and seven previously conducted surveys within a mile of the project; however, none of these sites fall within the project area. The Washington Department of Archaeological and Historical Preservation’s predictive model places the project area within an area of “Very High Probability” for encountering cultural resources based on environmental factors.
Plateau archaeologists conducted pedestrian survey that covered the entire project area, and placed five subsurface probes where possible, based on surface conditions and the location of subsurface utilities. No pre-contact or historic-era cultural materials or features were identified during the pedestrian survey or the subsurface probing. Plateau recommends that the proposed undertaking will not affect historic properties, and no further archaeological investigations are recommended prior to, or during, execution of this project.
Location: Lincoln County, Washington
