Drainage Solutions in Portland
Drainage in Portland is the most complex jurisdiction we work in. BES stormwater rules apply to many projects. Tree code constrains trench routing. Each neighborhood has its own quirks — we evaluate property-by-property.
About working in Portland
What we've learned installing drainage solutions in Portland.
Portland is the largest city in our service area, but we're selective about which neighborhoods we take work in. We focus on the close-in southwest and inner-east neighborhoods where the project profiles fit our crew strengths — hardscape, drainage, and full-yard transformations on established residential lots.
Terrain & soil
Massively variable. Southwest has hills and basalt; east of the river is mostly flat alluvial soil; the hills above Burnside are deep loam over clay. Drainage planning has to be done lot-by-lot in Portland more than anywhere else in our footprint.
Properties we work on
Anything from 1900s craftsman bungalows on 0.1 acre to 1+ acre lots in the Southwest hills. Mature landscapes are the norm — most projects involve working around existing trees, hardscape, and infrastructure.
Neighborhoods we serve
- Southwest Portland (Multnomah, Hillsdale, Burlingame)
- Sellwood-Moreland
- Eastmoreland
- Laurelhurst
- Hawthorne
Permits in Portland
Portland's permit process is the most complex in our service area. Tree code, BES (Bureau of Environmental Services) stormwater requirements, and historic overlays all kick in depending on neighborhood. We quote permit timelines conservatively here.

Common questions
What Portland 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.
What areas do you serve?
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.
Are you licensed and insured?
