West Linn Concrete on Hills, Rock and Rivers
West Linn's motto is "City of Hills, Trees and Rivers," and each of those shapes what homeowners need from concrete contractors in West Linn. The city sits at about 679 feet, between the Willamette and Tualatin rivers, and many lots are sloped and wooded. The 2020 census counted 27,373 residents and 10,491 housing units. We pour and replace driveways, patios, walks, steps and slabs across the city.
Old townsites and newer hillsides
West Linn incorporated in 1913 and merged with the town of Willamette in 1916. It also takes in former townsites such as Bolton, Multnomah City, Sunset City and West Oregon City, and later annexed Cedaroak, Marylhurst and Hidden Springs. The population grew from 3,933 in 1960 to 16,367 in 1990 and 22,261 in 2000. That mix means you can find an early 1900s house in the Historic Willamette area and a 1990s home in Tanner Basin within a few miles. The concrete on each tells a different story, and we plan the work to suit the house.
Building on rock and slope
Part of West Linn sits on rocky ground left by the Ice Age floods. The 26-acre Camassia Natural Area, for example, is on a rocky plateau exposed by the Bretz Floods. On hillside lots, excavation can hit rock or a thin layer of soil over it, and driveways often have steep runs and tight turns. We set grade carefully, compact a solid base, and use a broom finish across the slope for traction. Where water runs downhill toward the garage or the house, we plan drainage at the top and bottom of the slab.
West Linn's climate data lists about 44 inches of precipitation a year, more than the valley floor around Tigard, so drainage matters even more here.
Tree permits and concrete layout
West Linn requires a tree removal permit for most trees 12 inches or more in trunk diameter, and for Oregon white oak, Pacific madrone and Pacific dogwood at 6 inches or more. Removing a street tree requires a Street Tree Replacement Form. Processing can take up to 30 business days, including a decision period and an appeal period. Because so many lots are wooded, we design driveways and patios to avoid removals where possible, and if one is unavoidable, we build the permit timeline into the schedule.
Access on hillside streets
Many West Linn streets are narrow and steep, with tight turns and little room to stage equipment. We plan truck placement, pump use and the order of work around the site, and we protect neighbors' driveways and landscaping on the route in. On a sloped driveway pour, we place and finish from the bottom up and control the mix so it holds its position on the grade.
At the falls
The Willamette Falls Locks, completed in 1873, made the falls passable to river traffic; they closed in 2011. The T. W. Sullivan Hydroelectric Plant and the Willamette Falls Pulp and Paper Company both started in 1889. Homes in the older Willamette area near the river have some of the city's oldest walks and steps.
