Land surveyors - King County
Bellevue's neighbourhoods were mostly platted in the postwar decades, including Lake Hills in the late 1950s and Somerset's 22 divisions through the 1970s, while downtown towers and the Lake Washington, Lake Sammamish and Mercer Slough edges add commercial and shoreline work.
Most of Bellevue's residential ground was platted in one burst after the Second World War, when farmland east of the lake gave way to subdivisions along the new highway corridors at Eastgate, Newport Hills and Lake Hills. Lake Hills itself began in the late 1950s as a planned community built around its shopping center and joined the city in 1969; Crossroads was annexed in 1964, two years after its shopping center opened. Those plats are now sixty-plus years old, and the ramblers and split-levels on them are being replaced one lot at a time. A teardown on a 1950s plat often turns up original corner monuments that have been disturbed by decades of fencing, driveway and sewer work.
Somerset, above I-90, was built out in 22 divisions between the early 1960s and the late 1970s, which means neighbouring streets can sit on plats recorded more than a decade apart. The hill gives those homes their views and also gives them steep side yards, rockeries and retaining walls that frequently wander off the platted line. Bellevue's Development Services review treats steep slopes as critical areas, so a remodel on the hill usually needs the grade mapped before the design is settled.
Lake Washington frontage around Meydenbauer Bay and the west side, Lake Sammamish frontage on the east, and the Mercer Slough wetlands between them put a large share of the city near regulated shoreline. Dock, bulkhead and shoreline setback questions all depend on where the ordinary high water mark is actually located, not where an old deed places the water.
Downtown office and residential towers, and the Bel-Red redevelopment, generate steady ALTA/NSPS survey work for lenders and buyers, followed by construction staking once a project breaks ground and an as-built survey at completion. On the postwar plats the usual sequence is a boundary survey plus a topographic survey ahead of a rebuild. Larger lots in Lake Hills and Newport Hills are candidates for a short plat, while neighbours trading a strip of hillside use a lot line adjustment. Low ground near Mercer Slough and the lakeshore is where an elevation certificate comes up. Across the water, see Mercer Island, or north toward Kirkland.
