The Town of Twisp is planning to construct a tennis court and associated trail. The area of potential effect covers 0.3 acres within Twisp Park. The project includes the installation of concrete slab for the tennis court, measuring 120 feet long by 60 feet wide.
The cultural resource survey for the Twisp Tennis Court Project was intended to identify potential archaeological resources and potential historic properties in the Project Area prior to planned ground disturbing activities. A review of previously recorded cultural resources and archaeological surveys found 13 archaeological resources and 26 previously conducted surveys within 1.0-mile of the Project Area; however, none of these sites fall within the Project Area.
The archaeological fieldwork was completed and included inspection techniques to identify both surface and subsurface archaeological resources. Plateau archaeologists conducted pedestrian survey that covered the entire Project Area, and placed 5 subsurface probes where possible, based on the location of subsurface utilities, resulting in no additional cultural resources located.
Given the lack of identified cultural materials during the field survey, Plateau recommended that this project result in No Historic Properties Affected. However, given the findings of the background research, and out of an abundance of caution, Plateau recommended that all ground disturbing activities take place under the guidance of an Inadvertent Discovery Plan. In the event that cultural materials are encountered during implementation of this project, the IDP provides appropriate protocols and procedures to follow in accordance with state and federal laws.
