The Microsoft campus is within incorporated Redmond. https://aqua.kingcounty.gov/gis/web/VMC/misc/KC_HwysCitiesHS.pdf https://aqua.kingcounty.gov/gis/web/VMC/misc/KC_HwysCitiesHS... The only unincorporated land in that area is Marymoor Park and Bridle Trails State Park. The Link Light Rail will be opening a station next to the Microsoft campus in 2023, and Microsoft is paying to build a bike/pedestrian bridge over 520 at that location.
