Bob and his team planted a row of privacy hedges along my fence. He was responsive, knowledgeable and his crew did a great job with the trees. Would recommend!

Expert Retaining Walls in Premier Outdoor Spaces In The PNW
Retaining walls are one of the most practical landscape construction solutions for Snohomish County properties. The county's hilly terrain, with elevations ranging from sea level to over 1,500 feet, means many yards lose usable space to steep slopes and runoff. Snohomish County soils also tend toward clay and glacial till, which shift seasonally and hold water, putting extra pressure on any wall that isn't built correctly. At Summit Landscape Company Snohomish, we assess your slope angle, soil conditions, and drainage patterns before recommending a wall type and design. We build walls with proper gravel backfill and drainage systems to manage the region's heavy rainfall and prevent hydrostatic pressure buildup. Whether you need a single low wall to level a planting bed or a terraced system to tame a steep backyard, we size and build each wall to match your site. The result is stable ground, reduced erosion, and yard space you can actually use. Contact Summit Landscape Company Snohomish to schedule a site assessment.

FAQ
Retaining Walls FAQ
Common questions about retaining walls in Premier Outdoor Spaces in the PNW.
Retaining walls over 4 feet tall in Snohomish County require a building permit and engineered plans. Walls 4 feet and under are generally exempt, unless they support a surcharge such as a driveway or fill material above them.
Most retaining wall failures in Snohomish County come from poor drainage behind the wall. Clay-heavy soils hold water and build up hydrostatic pressure, which pushes the wall outward over time if gravel backfill and drainage pipes are not installed correctly.
A terraced wall system works well for steep slopes in Snohomish County because it breaks one tall wall into multiple shorter walls, reducing the soil load on any single structure. The right design depends on your slope angle, soil type, and how you plan to use the space.
Yes, we assess site access as part of every retaining wall evaluation in Snohomish County. Tight access affects equipment selection and material delivery, so we plan for those conditions before work begins.
Signs that a retaining wall needs attention include visible leaning, bulging, cracking, or soil washing out from behind or beneath the wall. Snohomish County's wet winters accelerate these issues, especially in walls without adequate drainage.
Yes, we handle site grading and wall construction together as part of our landscape construction work in Snohomish County. Combining both scopes means the grading and drainage work supports the wall from the start.
