Drainage Solutions in Lake Oswego
Drainage in Lake Oswego varies by property. The deeper well-drained loam in many neighborhoods means drainage is sometimes less critical than in clay-heavy cities, but lake-adjacent and hillside properties still need careful planning. Tree preservation rules constrain trench routing.
About working in Lake Oswego
What we've learned installing drainage solutions in Lake Oswego.
Lake Oswego is our highest-end project territory. Premium homes, mature landscapes, and demanding aesthetics mean we spec natural stone, engineered drainage, and architectural integration on most jobs. The bar for finish quality is higher here than anywhere else in our footprint.
Terrain & soil
Hillside lots dominate the older neighborhoods around the lake. Soils are deep, well-drained loam in most areas — better natural drainage than the I-5 corridor average. Slope work is common but less extreme than West Linn.
Properties we work on
Premium residential market. Properties run 0.25-1+ acre with established trees, lake views (for the premium tier), and architecturally significant homes spanning every decade from 1920s craftsman to 2020s modern. Lake frontage and Oswego Lake Corporation rules apply to lake-adjacent properties.

Permits in Lake Oswego
Lake Oswego's permit process is more involved than smaller cities — design review applies to many properties, and tree preservation is taken seriously. We plan permit timelines conservatively and coordinate the review with the homeowner from quote stage onward.

Common questions
What Lake Oswego 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.

We work the I-5 corridor from Canby (our HQ) through Aurora, Hubbard, Oregon City, West Linn, Wilsonville, Tualatin, Sherwood, Lake Oswego, Portland, and Salem.
