Re:Archaeology -Survey Requested,More information requested
Dear Ms.Timmons:
Thank you for contacting the Washington State Historic Preservation Officer (SHPO)and Department of
Archaeology and Historic Preservation (DAHP)and providing documentation regarding the above
referenced project.As a result of our review,our professional opinion is that the project area has the
potential to contain archaeological resources.Identification of cultural resources during construction is
not a recommended detection method because inadvertent discoveries often result in costly construction
delays and damage to the resource.We request a professional archaeological survey of the project area be
conducted prior to ground disturbing activities.The survey should be provided to DAHP and the
interested Tribes prior to ground disturbance.We also recommend consultation with the concerned
