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.

- Dry wells where no gravity outlet exists
- Corrective grading and swales
Clark County sits on heavy clay and takes roughly forty inches of rain a year, most of it between October and May. 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
Why does my yard hold water all winter?
Almost always a combination of Clark County clay subsoil, compaction from construction equipment, and a grade that does not fall anywhere. Clay drains extremely slowly, so once the top few inches saturate in November, additional rain has nowhere to go until spring. The fix is giving the water a path out rather than waiting for it to soak in.
How much does a French drain cost?
It depends on length, depth, whether we can get a machine to the trench line, what the trench has to cross, and how far the outlet is. A short run in an open back yard is a very different job from a hundred feet of hand-dug trench between a fence and a house. We price it after walking it, and the number we give you is fixed.
Can I just fill in the low spot with soil?
Occasionally, if it is a genuinely isolated dip. Usually it moves the problem rather than solving it, because the water still has nowhere to go and simply ponds at the new low point. If the water is arriving from uphill or from your roof, filling does nothing.
