What Mercer Island brings
The island climbs from 18 feet at the Lake Washington shoreline to 394 feet on a plateau that runs north to south through its center, cut by a series of ravines, and its 10,570 housing units filled in steadily after the first floating bridge opened in 1940. Ravine shade and shoreline damp keep the wet half of the year working on interiors and exteriors alike: mildew in baths and on north-facing sills, moss and algae on decks, roofs and walkways, rain-tracked grit at the door, and low winter light that shows every streak on lake-view windows.
Retail and offices concentrate in Town Center, the roughly 70-acre district that was a separately incorporated town until the two municipalities merged in 1970 and that gained a 2 Line light rail station in the Interstate 90 median in March 2026, while the Mercer Island School District runs six schools and about 4,000 students from 4160 86th Avenue SE.
