A significant residential population is developing in the downtown core, as more high-rise condominium and apartment complexes are built. The area also contains long-standing well-maintained single-family neighborhoods to the north and south, sharply delineated from the high-density downtown by Main Street on the south and Northeast 12th Street on the north. The vast Mercer Slough Park, a unique wetlands habitat and recreational area, and Bellevue Downtown Park – acclaimed for its award-winning “belvedere” design – are also landmarks of West Bellevue.
