STATEMENT OF WORK

Repair of the Tenasillahe Island Dock & Ramp March 17, 2021

1. GENERAL:

1.1 The US Fish and Wildlife Service (Service) requires an experienced marine contractor to conduct repairs of a dock with attached ramp on the Tenasillahe Island Unit of the Julia Butler Hansen Refuge for the Columbian White-tailed Deer (JBH Refuge), located in Clatsop County, Oregon.

This includes habitat management and levee maintenance projects that are directly tied to the protection and enhancement of the threatened Columbian white-tailed deer on Tenasillahe Island (one of only two secure subpopulations). The dock and ramp are required to move equipment, cattle, etc. between Tenasillahe Island and the Refuge Mainland Unit, Cathlamet, Wahkiakum County, Washington.
