The Town of Winthrop is planning additional water system improvements which implements aspects of the Town’s six year plan addressing water quality, reliability, maximum demand, and flow. The area of potential effect (APE) covers approximately 11.9 acres. Phase 2 of the project includes replacement of approximately 1,620 linear feet of 6-inch waterline with 12-inch waterline. This phase is located along State Route 20. Phase 3 of the project includes the replacement of 1,400 linear feet of 6-inch waterline with 8-inch waterline, and installation of about 2,250 linear feet of new 8-inch waterline to create a loop in a dead-end water main and increase quality.
This project is partly funded by a Drinking Water State Revolving Fund (DWSRF) grant provided by the Washington Department of Health, the Town of Winthrop must meet the requirements of the Section 106 of the National Historic Preservation Act, and consider the potential impacts to historic properties prior to project execution.
The pedestrian survey and subsurface investigations for the Winthrop Water System Phase 2 and 3 Improvements Project resulted in no newly recorded archaeological resources during the pedestrian survey or subsurface investigations. The proposed undertaking will result in No Historic Properties Affected, and no further archaeological investigations were recommended prior to, or during, execution of this project.
Location: Okanogan County, Washington
