Excavation Contractors in Vancouver, WA

Excavation contractors in Vancouver work across a city of 190,915 people (2020), estimated at 199,698 by 2025, sitting at about 180 feet on the north bank of the Columbia across from Portland. Fort Vancouver began as a Hudson's Bay Company post in 1825, and the city incorporated on January 23, 1857. Housing units grew from 70,005 in 2010 to 81,809 in 2020, so both very old and very new homes need earthwork.

The terraces

The Missoula floods left a staircase of terraces across Clark County, named the "Heights," "Mill Plain," "Fourth Plain" and "Fifth Plain." Those names are now major east-west streets. Many neighborhoods sit on fast-draining gravel; the USDA Sifton soil series has its type location in east Vancouver near NE 86th Street, with very gravelly coarse sand under volcanic ash. Drywells often work well there, but deep trenches in loose gravel need protection against caving.

Older west side, wartime neighborhoods

West Vancouver holds downtown and most historic areas. During World War II, developments like Fruit Valley, Fourth Plain Village, Bagley Downs, Ogden Meadows, Burton Homes and McLoughlin Heights went up and were later annexed. Homes of that age need sewer laterals, water services and drainage repairs.

Weather

The climate table shows about 37.47 inches of precipitation on 161 days a year, and only about 2.8 inches of snow. Cold east winds pour down the Columbia River Gorge, and silver thaw ice storms can shut the city down. The 1948 flood nearly topped the piers of the Interstate Bridge.

Permits

The City of Vancouver handles permits inside city limits; Clark County handles the unincorporated communities around it. Right-of-way work, drywells and tree removal each have their own rules, and we check what applies to your address.

Infill and ADUs

ADUs and infill homes on existing lots need footings, utility trenches and drainage squeezed onto small lots between existing homes.
