Local governments in the central Puget Sound region are moving to restrict new federal immigration detention sites, a shift that may have implications for communities farther south, including those along the I‑5 corridor in Cowlitz County.

According to reporting by The Seattle Times, the Tukwila City Council voted on Monday to prohibit the development of any new U.S. Immigration and Customs Enforcement (ICE) detention or correctional facilities within city limits. The vote followed public comment from 25 speakers who opposed additional ICE presence in Tukwila.

ICE currently operates a Department of Homeland Security office in the city, and according to reporting by WIRED, the agency had planned to expand into an 85,000‑square‑foot building in the Riverfront Technical Park. Property records identify the building’s owner as Sabey Corporation, which also owns a DHS facility on Tukwila International Boulevard. The site has not been finalized for ICE use, and a “For Lease” sign remains posted on the property, according to MyNorthwest. The building is located near King County International Airport, where ICE runs deportation flights out of Washington.

The Seattle Times reported that Tukwila’s measure blocks rezones and local permits related to detention centers but does not apply to private lease agreements, which do not require city approval. ICE did not confirm its current plans in comments to The Seattle Times, and the agency did not provide additional public statements.

Seattle officials are considering a similar citywide pause on new detention centers. According to reporting by The Seattle Times, the proposed Seattle legislation would enact a one‑year halt on any major additions to public or private jail or detention facilities. Discussions began after a December posting on the U.S. General Services Administration’s website sought feedback on a potential new immigration detention facility in Seattle. Councilmember Alexis Mercedes Rinck told The Seattle Times that such a facility would not align with the city’s stated goals as a welcoming jurisdiction.

Earlier this month, SeaTac adopted its own moratorium. According to reporting by The SeaTac Blog, the SeaTac City Council barred the creation or expansion of federal detention centers within city limits. SeaTac City Manager Jonathan Young told the council that further expansion of federal detention operations would likely conflict with the community’s safety needs, according to The SeaTac Blog.

SeaTac officials also reviewed the city’s use of Flock license‑plate‑reader cameras and opted to limit access while state lawmakers consider Senate Bill 6002, which could alter how such data systems may be used across Washington.

While Tukwila, Seattle, and SeaTac are separated from Cowlitz County by more than 100 miles, these decisions highlight emerging local‑control strategies around federal detention activity—an issue that has periodically surfaced in Southwest Washington as federal contractors and agencies evaluate real estate options along the I‑5 corridor. No similar proposals have been publicly discussed by local governments in Longview or Kelso this year, but the actions taken farther north demonstrate how quickly such proposals can prompt municipal responses.

Why this matters for Southwest Washington

Immigration enforcement infrastructure—whether proposed office relocations, detention centers, or transportation hubs—often follows transportation corridors. As metropolitan governments set limits on new or expanded facilities, federal agencies may shift their focus to suburban or smaller‑city markets where zoning regulations are less restrictive. For cities in Cowlitz County, the policy direction in the Puget Sound region serves as an early indicator of how other municipalities are responding to prospective ICE or DHS expansions.

Any future proposal affecting Southwest Washington would likely require coordinated review of land‑use law, public safety considerations, and community impact—issues that have been central to the debates unfolding in Tukwila, SeaTac, and Seattle.
