Drainage Solutions in Sherwood
Drainage in Sherwood is split — newer subdivisions usually have functional drainage by design; older streets sometimes need help with grading or downspout management. Heavier clay on the Bull Mountain slopes adds a layer of planning for the rising-terrain properties.
About working in Sherwood
What we've learned installing drainage solutions in Sherwood.
Sherwood has been one of the fastest-growing cities in our service area for the last decade. Newer construction, family-heavy neighborhoods, and rapidly maturing landscapes mean we see a strong mix of fresh installs and refresh/redesign work.
Terrain & soil
Mostly flat to gently rolling. Soils transition from the loamy Tualatin Basin profile in the lower elevations to clay-heavier on the rising terrain toward Bull Mountain. Drainage planning is generally straightforward unless the lot is on the south-facing slopes.
Properties we work on
Heavy concentration of 2000s-2020s subdivision construction. Lots run 0.15-0.3 acre with mature landscaping starting to need refresh on the older streets. Family demographics mean kid- and pet-friendly designs are a constant — turf, soft hardscape edges, room for play.

Common questions
What Sherwood homeowners ask about drainage solutions.
Why does my yard have standing water?
Usually one of three things: grade slopes water toward the house instead of away, soil is too compacted to absorb runoff, or roof downspouts dump too close to the foundation. We diagnose during the free site visit (ideally during or right after a rain).
What's the difference between a french drain and a channel drain?
A french drain is a perforated pipe buried in gravel that collects subsurface water — best for soggy lawns and slope runoff. A channel drain is a surface grate across driveways or walkways that catches sheet runoff. We often combine both depending on what's actually moving water on your property.
How much do drainage solutions cost?
Simple downspout extensions and surface grading start around $1,500. Full french drain systems with restoration run $4,000–$12,000. Foundation drainage repairs can run higher. We give a locked quote after the site visit.
Will drainage work damage my existing landscape?
We minimize disturbance and restore everything we touch — sod, plants, hardscape edges. Drainage often hides under landscape once we're done; you shouldn't see it.
Do you require an upfront payment?
No. We never require upfront payment. The free site visit gives you a locked quote, and you're not invoiced until the work is complete.
