What is the Territorial Sea Plan?

The State of Oregon holds the waters, shoreline, and living resources of its shoreline in trust for the public. The state has therefore established in law a program of planning and management that includes ocean resource goals and policies. The Oregon Territorial Sea Plan (TSP) was first adopted in 1994 and provides detailed guidance to state and federal agencies to manage uses within the state’s territorial sea, from shore to three nautical miles offshore. State ocean resources are governed by a tapestry of authorities at multiple government scales, and the TSP acts as a coordinating framework from which individual agencies institute regulations and management activities. 

The Ocean Policy Advisory Council (OPAC) was given the responsibility of stewarding the TSP, in conjunction with the Oregon Land Conservation and Development, when necessary to deal with new concerns as they occur.

Updating the Rocky Habitat Management Strategy, May 2023

May 2023 UPDATE:
On April 20, 2023 The Land Conservation and Development Commission unanimously adopted an amendment to Part Three of the Oregon Territorial Sea Plan (TSP), the Rocky Habitat Management Strategy. The decision added six new management areas that reflect the needs of the communities that proposed them. Rocky Habitat Management Areas focus on balancing use and conservation through the enhancement of visitor experiences with education and interpretation to limit wildlife disturbance and habitat degradation.

These designations completes a multiple year effort led by the Ocean Policy Advisory Council to revise the Management Strategy and was focused on site management designations along areas of Oregon’s iconic rocky shoreline. The effort included extensive input from agencies, organizations, governments, and general rocky coast users on revisions to the Plan.

To learn more about each of the recommended sites, you can view the Further Evaluation Workshops page, or watch the OPAC meeting videos from September 29 or December 9.    

Managing Oregon's rocky coastline is a shared responsibility. In fall 2018, the Oregon Department of Land Conservation and Development (DLCD) gathered decision makers across the state to begin an amendment to the Rocky Shores Management chapter (Part Three) of the Oregon Territorial Sea Plan (TSP). The plan acts as a coordinated vision for marine resources in Oregon and guides the actions of state and federal agencies that are responsible for managing coastal and ocean resources in the public trust. The amended rocky habitat plan will incorporate the best available science and consider the needs, concerns, and values of Oregonians balanced with the state’s goals for a resilient coastal ecosystem that can provide enduring opportunities for its users.
The rocky habitat site management proposal process is tentatively planned to re-open for submissions October 1, 2023. 
Access the Rocky Habitat Web Mapping Tool here:
The new Rocky Habitat Web Mapping Tool contains a wealth of coastal resource information, and provides an opportunity for interested members of the public to generate and submit proposals for coordinated management changes to Oregon's marine rocky habitats. Site designation proposals collected by this tool will be reviewed for potential incorporation into the Rocky Habitat Management Strategy.

Plan History

In 1991 the Oregon Legislature amended ORS chapter 196 to establish the Ocean Policy Advisory Council (OPAC) made up of a variety of ocean stakeholders, local governments, and state agencies, and charged it with providing the governor and state agencies with policy advice on ocean matters. The legislation gave the Department of Land Conservation and Development (DLCD), which includes the state’s federally-approved coastal management program, primary responsibility for ocean planning and providing assistance to OPAC. One of OPAC’s basic duties was to prepare a Territorial Sea Plan (TSP) for managing the resources and activities in the state's territorial sea.

Territorial Sea Plan Part Five: Marine Renewable Energy Development

Part Five of Oregon's Territorial Sea Plan describes the process for making decisions concerning the development of renewable energy facilities (e.g. wind, wave, current, thermal, etc.) in the state territorial sea, and specifies the areas where that development may be sited.  The requirements of Part Five are intended to protect areas important to renewable marine resources (i.e. living marine organisms), ecosystem integrity, marine habitat and areas important to fisheries from the potential adverse effects of renewable energy development (facility siting, development, operation, and decommissioning).  Part Five provides a system to identify the appropriate locations for that development which minimize the potential adverse impacts to existing ocean resource users and coastal communities.

Public comment is scheduled into meeting agendas.
Meeting Protocol for Public Comment 
To allow the Working Group to have efficient discussions during meeting:
  • Public comment will only be accepted during predetermined public comment agenda items (~15 minute at beginning and end of meeting).
  • In the event a large number of individuals would like to comment, time will be divided to allow all parties an equal amount of time to speak.
  • Additional dialog and questioning between the Working Group and the commenting entity should be avoided to keep meetings on track. 


Offer comment during a formal comment period

Once the Working Group has reviewed submitted site proposals, a formal 30-day public comment period will be opened. Check back here or sign up for email updates for information about public comment opportunities and events.

If you have a question or if you are affiliated with a group requiring government consultation please contact the Working Group
chair person or staff member.

Resource Inventory Maps

Informed decision making, the heart of Goal 19 and the Oregon Ocean Plan, depends upon adequate information about ocean resources and uses and the effects of any proposed action on those resources and uses. This page contains information about ocean and coastal resource inventories, as well as interactive maps of existing resource inventory information.
