Project Overview

The Tideflats subarea planning process is intended to create a shared long-term vision and more coordinated approach to development, environmental review, and strategic capital investments in the Tideflats. Completion of the subarea plan will support the ongoing eligibility for and prioritization of transportation funding in the regional manufacturing and industrial center.


The overarching themes for the subarea planning process will include:

  • Economic Prosperity for All
  • Environmental Remediation and Protection
  • Transportation and Capital Facilities Planning
  • Public Participation and Outreach

See the Tideflats Subarea Work Plan for more detailed information on anticipated planning outcomes.




Environmental Impact Statement

Determination of Significance

The City of Tacoma has determined that the Tacoma Tideflats Subarea Plan is likely to have a significant adverse environmental impact. An EIS under RCW 43.21C.030(2) (c) will be prepared.

Scoping and Alternatives

On October 18, 2022, the City Council affirmed the Steering Committee's recommended Alternatives as the basis for the Plan and EIS. The Alternatives include a No Action Alternative and three Action Alternatives. It is anticipated that the alternatives will be based on variations of elements such as the mix of industrial zoning and land uses, employment growth scenarios, transition areas, housing types and location, sea level rise adaptation strategies, fish and wildlife habitat restoration, and shoreline public access and recreation.

For purposes of the No Action Alternative, it is assumed that development would occur within the Tacoma Tideflats Subarea based on existing zoning and development standards. Development or redevelopment that is proposed within the Tacoma Tideflats Subarea in conjunction with the No Action Alternative would undergo environmental review on a project-by-project basis. Such projects would be subject to site-specific mitigation and potential SEPA-based appeals.

Environmental, Cultural and Economic Importance

The Tideflats is a unique environment containing shoreline, river deltas, tidal creeks, freshwater and salt marshes, naturalized creeks, and river channel corridors.


With an area of over 5,000 acres of waterfront land providing vital saltwater and estuarian habitat for salmon, shellfish and other marine life, the Tideflats is an economic center that includes industrial and manufacturing and maritime activity in a world class port and is the ancestral lands of the Puyallup Tribe of Indians.


The area is also designated as the Port of Tacoma Manufacturing Industrial Center (MIC). The MIC is home to Tacoma and Pierce County’s highest concentration of industrial and manufacturing activity and is the work site for about 9,800 employees.

In recognition of the regional significance of the MIC, the City of Tacoma, Port of Tacoma, Puyallup Tribe of Indians, City of Fife, and Pierce County have partnered to develop a Tideflats Subarea Plan for adoption by the City of Tacoma as part of the City’s Comprehensive Plan.


Geographic boundaries

The Plan area is based on the current Port of Tacoma Manufacturing Industrial Center (MIC) which is defined both in the Puget Sound Regional Council’s VISION 2040 as well as the City of Tacoma Comprehensive Plan.  However, studies and recommendations from the Plan process will likely extend beyond this Plan area, including the lands immediately adjacent to the MIC and depending on the topic under review (air and water quality, traffic impacts, freight corridors, land use transitions, economic impacts and strategies, etc.).


Planning for the Future

The Subarea Plan process will provide:

  • Potential text and map amendments to other elements of the City’s Comprehensive Plan
  • Potential Amendments to the City’s Land Use Regulatory Code
  • Potential amendments to City Zoning districts
  • Amendments to the Shoreline Master Program
  • Information to support local and regional Capital Facilities Programs
  • An environmental impact statement (EIS).


Frequently Asked Questions:

What State laws or planning requirements affect the subarea and development of the Subarea Plan?

The State of Washington has multiple layers of policies that come into play when developing a subarea plan. The Tideflats Subarea Plan must be consistent with the following:

  • State Environmental Policy Act (SEPA) environmental review
  • Growth Management Act (GMA)
  • Shoreline Management Act (SMA)
  • The Puyallup Land Claims Settlement
  • The Container Port Element and elements for certification of a Manufacturing and Industrial Center (MIC) by the Puget Sound Regional Council (PRSC)

How long will it take to complete the Tideflats Subarea Plan?

A Draft Subarea Plan and Final Environmental Impact Statement are anticipated to be completed by the end of 2022. 


Once completed, the Tideflats Subarea Plan (TSAP) Steering Committee will provide the City's Planning Commission with a recommendation on the Draft Subarea Plan. The City legislative process for approval of the Comprehensive Plan Amendment will then begin. This includes Planning Commission review and recommendation followed by City Council review and action. This legislative process could take up to an additional year.

Who approves the Tideflats Subarea Plan?

In accordance with the Comprehensive Plan, One Tacoma, the City Council has approval authority for the subarea plan.


In some cases, additional approvals or certifications may be required after the Council approves the plan. Any modifications to the City’s Shoreline Master Program, for example, must be reviewed and approved by the State Department of Ecology before those modifications take effect. In addition, the City must receive plan certification from the Puget Sound Regional Council to maintain transportation grant eligibility.


What is the Role of the Steering Committee and who is represented on it?

The Tideflats Subarea Plan is being jointly funded and developed through an interlocal agreement between the City of Tacoma, the Port of Tacoma, Puyallup Tribe of Indians, Pierce County and City of Fife. The Steering Committee is  comprised of two elected officials from each the partner governments. The role of the Steering Committee is to develop and recommend a draft Subarea Plan to the City of Tacoma Planning Commission and to provide continued comment and feedback throughout the City adoption process.

What is the role of the Tideflats Advisory Group and who is represented on it?

The Tideflats Work Plan specifies the stakeholder group, called the Tideflats Advisory Group (TAG), to include adjacent jurisdictions, neighborhood councils, business and industry professionals, labor groups, environmental subject matter experts and regional economic professionals. 


How can I provide comment during development of the Tideflats Subarea Plan?

The Tideflats Subarea Plan (TSAP) will be developed through an extensive public process. There will be opportunities for public comment on the scope of work and environmental review, opportunities to provide feedback on specific studies and plan proposals, and both the Planning Commission and City Council will conduct a public hearing on a Draft Subarea Plan.


The TSAP Steering Committee approved a Public Engagement Plan (PEP) that will guide outreach and engagement efforts and strategies.

Is the Northeast Tacoma Buffer Zone application being considered in the Tideflats Subarea Plan?

Yes, the application will be considered within the scope of work for the planning process. In March, 2017, the Northeast Tacoma Neighborhood Council submitted an application to amend the Comprehensive Plan and Land Use Regulatory Code to implement a buffer zone between the residential areas of Northeast Tacoma and the industrial tideflats along Marine View Drive. On May 9, 2017, the City Council adopted Resolution No. 39723, initiating the subarea planning process for the Tideflats. In addition, this Resolution directed staff to consolidate the application within the broader scope of work for the Tideflats Subarea Plan.


Does the Growth Management Act contemplate planning for ports?

In 2009, the Washington State Legislature amended the Growth Management Act (RCW 36.70A.085) to include a requirement for a Container Port Element in the Comprehensive Plan for cities that contain a marine container port with annual operating revenues in excess of $60 million. The City of Tacoma falls into this category.

Accordingly, the City of Tacoma, in collaboration with the Port of Tacoma, adopted a Container Port Element within the Comprehensive Plan in 2014. The element provides policy guidance to achieve the following:

  • Protection of core areas of container port and port-related industrial areas within the City;
  • Efficient access to the core area through freight corridors within the city limits;
  • Protection against potential land use conflicts along the edge of the core area; and
  • Identification of key transportation corridor improvements.

The Container Port Element is available on the City’s One Tacoma Comprehensive Plan webpage at cityoftacoma.org/onetacoma

What are the Interim Regulations and how are the Interim Regulations associated with the Tideflats Subarea Plan?

On November 21, 2017 the Tacoma City Council adopted Amended Ordinance No. 28470, establishing interim regulations for the Tideflats and other industrial zoning districts. The intent of the Interim Regulations is primarily to put a pause on certain land use and development that could impact the subarea planning process, and to maintain abaseline of use and development for review for the subarea plan Environmental Impact Statement(EIS).


As part of the recent extension of the Interim Regulations, the City Council directed the Planning Commission to reconsider the issues, update findings of fact, and provide a new recommendation to the City Council for land use code amendments that would replace the interim ordinance. For more information on this process, please visit, cityoftacoma.org/tideflatsinterim

Why is an Environmental Impact Statement (EIS) included in the subarea planning process?

By including the Environmental Impact Statement (EIS) in the subarea planning process, we can streamline implementation of projects that align with the approved subarea plan.


An EIS is prepared when a public agency proposes an action, such as adoption of a subarea plan, and determines that this action may result in significant adverse impacts. The EIS is a document that provides an impartial discussion of potential impacts of the proposal and measures to address those impacts. The EIS process provides public review and comment on the topics to be studied in the EIS (referred to as the scoping process) and on the Draft EIS findings.
