News report: Stargate Lighthouse Campus

Wisconsin Public Radio reported water, electricity, noise and transmission-route questions at a September 10, 2026 community event for Port Washington's Lighthouse campus. Earlier reporting described construction-noise, light and traffic complaints and a city-announced hours change. These are outlet accounts, not measured impacts, a formal complaint case or proof that every concern was resolved.

Record status: unknown. The current outcome of the documented resource and construction questions is unknown in this bounded review. A reported hours amendment and developer plans do not establish actual mitigation completion, measured noise or water conditions, current transmission approval or resolution of every concern.

Event date: September 10, 2026

Source publication date: September 11, 2026

Disposition date: Not established

Concern sources checked: October 18, 2026

The newer report's photo caption expressly identifies September 10, 2026 as the community conversation. This was a company informational event, not a formal agency hearing. The earlier reported hours amendment and its scheduled start are separate events. The original current report was published September 11, 2026 and updated that day; the construction-hours report was published March 20. The original company campus page has no independently established first publication day.

Company-published statement

Vantage Data Centers stated that Lighthouse would use closed-loop cooling and that it plans water restoration, wetland measures and a planted berm for sound mitigation. These are company plans and commitments, not independently verified water use, completed mitigation or permit outcomes.

The original campus page explicitly identifies Port Washington and Lighthouse. Its resource and design statements relate to the reported questions, but it is not an express reply to every construction complaint or an original transmission decision. First publication date is unknown.

Counts describe attributed documentation, not harm or severity. Allegations, procedural outcomes and published replies retain their separate scope.

News report: Microsoft Mount Pleasant Data Center Campus

Wisconsin Public Radio reported a lawsuit alleging noise at Microsoft's Fairwater facility in Mount Pleasant, alongside separate construction-dust, light and traffic concerns elsewhere on the campus. This is an outlet report of allegations and community questions, not an independently inspected court filing, measured impacts or a current compliance finding.

Record status: unknown. The present lawsuit disposition and outcome of the documented concerns are unknown in this bounded review. Microsoft's statements about mitigation and ordinance compliance are company positions, not independently checked measurements, a final case decision or resolution of all campus construction concerns.

Event date: Not established

Source publication date: July 2, 2026

Disposition date: Not established

Concern sources checked: October 18, 2026

The report describes a Wednesday lawsuit filing but no independently inspected original complaint or exact filing date was established in this bounded review. Event date remains unknown; a day was not inferred from the publication calendar. The original WPR report was published July 2, 2026. The selected company update is explicitly dated July 20; earlier June 18 and April updates are separate statements. The exact first creation date of the changing company page is unknown.

Raised or recorded by Wisconsin Public Radio.

Company-published statement

Microsoft stated in its July 20 update that sound evaluation, short-term mitigation and monitoring were continuing, with additional sound-reduction measures under evaluation. These are company reports, not an independently verified noise result, current compliance determination or final lawsuit outcome.

The original dated update concerns Mount Pleasant Fairwater 1 and the reported humming sound. It is later than the WPR report, but it does not expressly answer every lawsuit allegation or the separate construction-dust, light and traffic questions elsewhere on the campus.

Response publication date: July 20, 2026
