Impact analysis
Microsoft is already the city's top taxpayer at roughly $11 million a year in property tax, and the annexation brings more tax base but also infrastructure obligations.
Landowners selling the property, Microsoft, construction and tech workers, and the city's tax base.
Nearby Sweetgrass and county residents fear noise, water strain, and property value losses; the city loses negotiating leverage once land is zoned.

The council advanced the largest annexation in city history — about 3,460 acres for a possible Microsoft data center campus.
