LANDSCAPE WATER MANAGEMENT
Drainage Solutions for Seattle-Area Landscapes
Standing water, excessive runoff, erosion, and poor drainage can damage landscapes and hardscapes and make outdoor spaces difficult to use. Seattle Rockeries provides professional drainage solutions designed for the wet climate, slopes, and challenging soil conditions found throughout the Seattle area.

Solutions for Yard and Landscape Drainage Problems
Effective drainage starts with understanding how water moves across your property. Low areas can collect water, slopes can direct runoff toward patios or other improvements, and poorly managed drainage can contribute to erosion and unstable soil.
Seattle Rockeries evaluates the conditions affecting your property and develops drainage and grading solutions that help move, collect, or disperse excess water. Depending on the site, a project may incorporate one or more drainage methods.
Our Landscape Drainage Services
French Drains
French drains collect subsurface and surface water and redirect it to a more appropriate location. They can be particularly useful where water collects along slopes, landscape features, or retaining walls.
Dry Wells
Where site conditions permit, a dry well can collect runoff and allow water to disperse gradually into the surrounding soil rather than remaining on the surface.
Swales
Carefully shaped landscape swales can help direct surface runoff across a property while integrating naturally with the surrounding landscape.
Landscape Grading
Proper grading reshapes the landscape to encourage water to flow away from problem areas. Grading may be used on its own or as part of a larger drainage solution.
Erosion Control
On sloped properties, uncontrolled runoff can carry away soil and affect landscape stability. Drainage improvements can be combined with rockeries, retaining walls, terracing, and other measures to help manage runoff and erosion.
Integrated Drainage Solutions
Drainage problems do not always have a single solution. Depending on the property, Seattle Rockeries can combine grading, drains, swales, and hardscape improvements into a coordinated approach to water management.
Drainage Designed for Pacific Northwest Conditions
Western Washington's rainy season can expose drainage problems that are less noticeable during the drier summer months. Repeated rainfall can saturate soil, create standing water, increase runoff, and contribute to erosion, particularly on sloped properties.
Seattle Rockeries has extensive experience working with the terrain and outdoor construction challenges found throughout the Seattle area. We look at drainage as part of the overall landscape rather than treating water problems in isolation.
Drainage and Retaining Walls
Water management is especially important around retaining walls. Water accumulating behind a wall can increase pressure and contribute to long-term performance problems. Proper drainage may include drain rock, drainage pipe, grading, or other measures appropriate to the wall and site conditions.
If your project involves both drainage and a retaining wall, Seattle Rockeries can evaluate how the two should work together. You can also learn more in our guide to proper drainage behind a retaining wall in the Pacific Northwest.
How We Approach a Drainage Project
Evaluate the Property
We look at slopes, low areas, runoff patterns, existing hardscapes, and other site conditions contributing to the drainage problem.
Identify the Right Solution
Based on the site, we determine whether grading, a French drain, dry well, swale, erosion-control measures, or a combination of approaches is appropriate.
Install the Drainage Improvements
Our team completes the necessary excavation, grading, drainage, and related landscape construction work.
Serving Seattle and the Eastside
Seattle Rockeries provides landscape drainage and hardscape services throughout Seattle and surrounding communities, including Bellevue, Issaquah, Kirkland, Mercer Island, Redmond, Renton, and Sammamish.
