Living in Mercer Slough

Mercer Slough is a quiet, nature-oriented neighborhood in south-central Bellevue defined by its proximity to the 320-acre Mercer Slough Nature Park — the largest remaining wetland on Lake Washington. The housing stock is almost entirely condos and townhomes, with no single-family inventory. The all-residential median price of $550K makes it one of the more affordable entry points into Bellevue, though transaction volume is extremely low (1-4 sales per quarter). The neighborhood appeals to nature lovers, kayakers, and buyers who want Bellevue School District access at a moderate price point.

Mercer Slough is defined by nature, not walkable errands. The 320-acre Mercer Slough Nature Park offers 7+ miles of boardwalks and trails, a u-pick blueberry farm, kayak/canoe water trails, the Winters House historic site, and the Environmental Education Center (run jointly with Pacific Science Center). Daily errands require a car — the nearest grocery and commercial options are in Factoria or Old Bellevue. The South Bellevue light rail station provides transit access to downtown Bellevue and Seattle.

Developments & What's Coming

Richards Valley Subarea Plan Update

Planned — 2027-20282028

City of Bellevue is scheduled to update the Richards Valley Subarea Plan in 2027-2028. The subarea, which borders Mercer Slough to the east, is envisioned for a mix of housing, retail, and small business uses. Current zoning allows light industrial and office; the update could unlock residential density.
