TSP Part Four
Uses of the Seafloor

Part Four of the Territorial Sea Plan relates to Uses of the Seafloor. Oregon’s coast is a prime landing zone for fiber-optic telecommunication cables that cross the ocean floor from sites around the Pacific Rim. Other utilities, such as natural gas pipelines, may eventually be routed across Oregon’s Territorial Seabed. Proper placement of utility easements and installation of fixtures is required to avoid damage to or conflict with other ocean uses, such as commercial fishing, and to reduce or avoid adverse effects on marine habitats.
