Tacoma adopts updated critical-area rules under Ordinance No. 29114

Tacoma has adopted updated regulations for environmentally sensitive and hazardous areas, changing the framework used to review some development, construction and other land-use activity.

The Tacoma City Council adopted Amended Substitute Ordinance No. 29114 on July 14, 2026. The ordinance updates the city’s Critical Areas Preservation Ordinance and amends Tacoma Municipal Code Chapter 13.01, which contains definitions, and Chapter 13.11, which governs critical-area preservation.

What Tacoma changed

The update is part of the periodic review required under Washington’s Growth Management Act. City materials say the revisions incorporate updated scientific information, align the regulations with the One Tacoma Comprehensive Plan and other applicable policies and laws, and respond to updated guidance for environmental conservation and natural hazards.

The ordinance addresses five categories of critical areas:

Wetlands;
Fish and wildlife habitat conservation areas, including streams and related habitat;
Critical aquifer recharge areas;
Frequently flooded areas; and
Geologically hazardous areas.

The city says the adopted revisions include updated guidance for wetlands and wetland buffers, stream buffers and Oregon white oak protections. The ordinance also updates definitions and procedural provisions.

What it means for property owners and developers

The changes do not apply uniformly to every property in Tacoma. Their practical effect depends on whether a site contains, borders or could affect a mapped critical area and on the type of proposed activity.

For property owners, developers and land-use applicants, work such as clearing, grading, construction or redevelopment may require additional site information, critical-area verification, environmental studies, buffers, vegetation protections, mitigation or other review steps. The updated definitions and standards may affect how an application is evaluated when environmentally sensitive areas or natural hazards are involved.

Applicants should not treat earlier draft amendments, Planning Commission materials or public comments as the final law. The Planning Commission recommended a revised draft after the public-review process, and the City Council later adopted Ordinance No. 29114. The enacted ordinance and any associated transition provisions control.

The ordinance changes regulatory standards. It does not, by itself, approve or reject a particular development project.

When the rules take effect

The council adopted the ordinance on July 14. Tacoma’s legal notice, published in the Tacoma Daily Index on July 16, stated that the council had passed Amended Substitute Ordinance No. 29114.

The city’s Critical Areas Ordinance Update page says the regulations take effect 10 days after the council decision is posted in the newspaper. Counting from the July 16 publication produces an apparent effective date of July 26, 2026. That date should remain a calculation rather than a fully confirmed legal conclusion until the final ordinance and publication record establish the effective-date language and any applicable transition provisions.

Existing permits and pending applications may be governed by vesting or other transition rules. Those provisions can determine whether a project is reviewed under earlier or updated standards.

Why the rules matter in Tacoma

Critical-area questions have surfaced in local development disputes, including the Preserve Tacoma project in South Tacoma. The News Tribune reported that neighbors raised concerns about possible eagle and hawk nesting areas during tree clearing, while the developer disputed the claims and city officials said they had not received verified information documenting an active eagle nest on or adjacent to the site.

That dispute is separate from Ordinance No. 29114 and does not establish why the council adopted the update. It does show why habitat information, environmental review and documentation can become important when development occurs near potentially sensitive areas.

What affected applicants should do

Property owners and applicants should check Tacoma’s critical-area mapping, confirm the status of any permit or land-use application, and review the final ordinance for effective-date and transition provisions.

For project-specific guidance, applicants should contact Tacoma Planning and Development Services. The ordinance establishes updated city standards, but its application depends on the site, proposed work and procedural status of each project.
