Neighborhood Livability

Community members in Tualatin are fighting for neighborhood livability, against the negative impacts of the Lam Research campus which include air pollution, noise pollution, and light pollution. Our efforts in 2024 and 2025 resulted in a significant redesign of Lam's TUX project and the prevention of major traffic problems. We are currenty working to stop Lam's Building B Chemical Management Systems (CMS) Expansion, as it poses grave risks to the health of the surrounding residents.

Chemical Release Plan

CMS Update

On Monday, October 12, 2026 despite compelling testimony and evidence in support of the land-use appeals, the Tualatin City Council voted unanimously to affirm the staff-level decision approving Lam’s Building B expansion. The City has once again missed a golden opportunity to protect the neighborhood from the foreseeable negative impacts of Lam's development. City Council voted on November 9, 2026 to finalize their decision and adopt Lam's findings.

Save Tualatin Road The City has taken the position that the issues raised by the community are performance standards not approval criteria and therefore Lam does not need to demonstrate compliance with any environmental regulations during the land use review process. Soon the City will mail their Notice of Decision to all who participated. Then, the community will have 21 days to decide if we want to appeal this to the Oregon Land Use Board of Appeals (LUBA).

Back in March 2026, Lam submitted this land use application (AR26-0002) to expand Building B, with a larger chemical management area, another scrubber exhaust, more air pollution, and more noise pollution beyond the scope of the TUX project (which was approved in 2025 and is currently under construction) The community submitted Public Comments in opposition. Two residents appealed the staff-level decision. A Public Hearing was held on 9/14/2026 (video) and the record is closed.

Despite Lam’s reassurances that no toxics are stored in the bulk gas yard, it turns out that Lam does store and use Extremely Hazardous Substances (EHS) onsite. The above image is from Lam's Offsite Chemical Release Plan which was first made public in September 2026.

Noise Ordinance Proposal

Tualatin's Noise Ordinance has a fatal flaw: Variances. The code currently allows any violator to apply for a variance (an exemption) and the City Manager can grant the variance without public notice, without public input, without a public hearing, and without even notifying the City Council.

The residents of Tualatin are requesting a new noise ordinance, and a moratorium on noise variances, in order to address the issues outlined in our Noise Ordinance Proposal. This is necessary to preserve and protect neighborhood livability.

Noise Pollution from Lam

Noise from Lam's Tualatin facility has plagued the nearby community for more than three years. Lam’s rooftop fans can be heard over a mile away on Durham Road in Tigard. Nearby Tualatin residents are being kept awake at night by this equipment. For the neighbors who live across the street from Lam’s gas plant, the continuous high-pitched hiss is a constant annoyance. Lam's noise model predicts that the TUX expansion will be even louder. Lam decided to locate their facility next to an established neighborhood, and Lam needs to operate in a way that is compatible with the surrounding community. We are asking Lam Research and the City of Tualatin to restore peace and quiet to our neighborhood.
