Drainage Solutions in Woodland, WA
High water table and floodplain ground. French drains, catch basins, downspout tightlines and regrading for yards that hold water every winter.
Free Estimate in WoodlandDrainage Solutions in Woodland: what is different here
Woodland has the hardest drainage conditions we work in. On low ground near the Lewis River, the winter water table can sit within a foot or two of the surface, and that changes the physics: a French drain moves water to a lower place, and if there is no lower place, it does nothing.
Where the water table is the problem, the answer is surface management rather than subsurface drainage. Raising planting beds and lawn areas above the wet zone, shaping swales to move surface water off, and choosing plants that tolerate wet feet all work with the site rather than fighting it. Contractors who install a standard French drain here take your money and leave you with the same wet yard.
Floodplain regulations apply to a number of Woodland properties and restrict fill and grading. It is worth confirming your flood zone before planning work that moves material.
How we build it
- On-site diagnosis before any pricing
- Washed drain rock and filter fabric on every French drain
- Catch basins and area drains at collection points
- Downspout tightlines routed well away from the foundation
- Dry wells where no gravity outlet exists
- Corrective grading and swales
Clark County takes about 37 inches of rain a year and under three inches of it falls in summer, so the wet season runs October through May. On the poorly drained soils that fill our basins and drainageways, water that has nowhere to go will find your lowest ground, your crawl space or the back of your retaining wall. Drainage is the least glamorous thing we do and by far the most valuable.
About 15 minutes north of Ridgefield up I-5. Estimates in Woodland are free, and the price we put in writing is the price.

Drainage Solutions in Woodland: questions we get
Will a French drain work if our water table is high?
Only if there is somewhere lower for the water to go. Low Woodland ground can have groundwater within a foot or two of the surface in midwinter, and a drain sitting below that is in water rather than collecting it. This is the first thing to establish before spending money here.
How do we find out where our winter water table sits?
By looking in winter, which is why we push for a wet-season assessment on low ground. Test holes tell you a great deal, and how the property behaves in January tells you the rest. Designing a system in August on a river-flat lot is guessing.
What works when there is nowhere lower to send the water?
Usually raising what matters above the problem rather than draining the whole site — building up planting areas, setting hardscape at a workable level and shaping the surface to move water — combined with a piped route to any genuine outlet, or a sump where there is truly no gravity option.
Why would a dry well be the wrong choice here?
Because it depends on the ground beneath accepting water. Where the winter water table is close to the surface, a dry well fills early in the season and stays full, leaving no capacity in exactly the months you needed it. On low ground it is frequently the wrong tool.
Are we allowed to regrade or bring in fill?
That depends on your flood zone. Properties on the flat near the Lewis River can sit in mapped floodplain, which restricts grading, fill and structures. Raising a low yard is exactly what a homeowner instinctively wants to do and exactly what those rules can limit, so confirm your position first.
Which authority handles drainage work here?
Woodland straddles the Clark and Cowlitz county line, so it depends where your address sits — and near the river there may be additional review. We confirm before quoting rather than assuming from the postal address, which is not a reliable guide in this area.
Do sump systems make sense on a Woodland lot?
Where there is genuinely no gravity outlet, sometimes it is the only honest answer. It is a mechanical system, so it needs power, maintenance and an acceptance that pumps fail. We would always look for a gravity solution first, but we will not invent one that is not there.
Is drainage worth doing before we build anything else?
On low ground near the river, emphatically. Water is the factor that decides what a property here can ever support, and everything else — patio, lawn, planting, walls — depends on it. Building first and draining afterwards is how people end up paying twice.
