West Seattle Trench drain gravel fill

Homeowner’s Issue

West Seattle yards face a familiar set of problems: heavy fall and winter rains, pockets of compacted glacial till, shallow topsoil on bluff edges, and shady corners that hold moss and runoff. Low spots near driveways and foundations collect water, and older curb cuts or compacted lawn strips can channel stormwater into lawns instead of letting it soak in. In neighborhoods from Admiral to High Point, tree roots and clay layers slow infiltration; near Alki and Lincoln Park you’ll see coarser soils but still heavy surface flow during storms.

Sun exposure varies block-to-block—south-facing slopes dry faster and support drought-tolerant plantings, while north or heavily treed lots stay wet and mossy. Many HOA rules in West Seattle favor tidy, low-profile drainage solutions that don’t block sightlines or neighbor access. City water-use advisories in midsummer make it smart to rely on passive infiltration systems instead of watering to compensate for poor draining soil. The result: without a planned trench drain and gravel fill, homeowners deal with muddy paths, stressed plants, and foundation risk. A sustainable, permeable trench filled with appropriately sized gravel and fabric lets water move where it belongs — into the ground — and reduces surface runoff that causes erosion and messy yards.

Our Quality Service

We design and install trench drains focused on local realities: correct slope, edge restraint where needed, and gravel media sized for Seattle rainfall patterns. Work begins with a site survey to map flow, identify utilities, and pick a route that meets HOA sightline rules and neighbor access. Typical install day includes excavation, laying geotextile fabric, graded gravel fill, and compacted top dress that blends into lawn or planting beds.

We use hand tools and small machinery to protect roots and minimize damage in tight West Seattle lots; larger builds get a compact excavator when access allows. Timelines: most small trenches finish in one day; longer runs or slope work may take two. We follow sustainable practices only—no herbicides—using organic weed control, compost-based topdress, and native-friendly edging. Benefits include safer walkways, reduced foundation moisture, improved curb appeal, and less weekly maintenance.

What’s Included

• On-site assessment and drain routing plan.
• Excavation to grade with proper fall for runoff.
• Geotextile fabric installation to limit fines.
• Gravel fill sized and compacted for infiltration.
• Surface blending: level finish that matches existing landscape.
• Site cleanup and disposal of excess soil (dump fees disclosed up front).

Options / upgrades:

• Biodegradable erosion control mat for steep runs.
• Extra gravel reserve for high-flow areas.
• Organic, manual weed control and moss scraping (no herbicides).
• Haul-away soil vs. green bin/composting options.
• Low-profile grate or stepping-stone finish where ADA or HOA requires.

Before & After / Expectations

Expect some noise during excavation and a day or two of disturbance; tight access yards may need more time. We leave the trench functional the same day; planting or turf repairs can follow once settled—usually within 1–3 weeks. Debris and excess soil are removed or staged per your choice; we disclose haul charges before work.

Care tips for West Seattle:

• Avoid heavy foot traffic on fresh fill for 48–72 hours.
• Inspect gravel in spring and after big storms; top-up if fines collect.
• Summer watering is rarely needed for trench areas; use water savings elsewhere.
• In shady, moss-prone corners prune canopy for airflow to reduce moss buildup.
• Annual hand-raking of visible detritus keeps infiltration working; we offer maintenance visits.

FAQs

• Q: How long does an average trench take?
  A: A standard 10–20 ft trench with gravel fill is usually completed in one day; longer or steep runs may need a second day.

• Q: Will this disturb tree roots?
  A: We plan routes to avoid major roots. When roots are unavoidable we use hand-excavation and root-safe practices to minimize impact.

• Q: Do you use chemicals to control weeds?
  A: No. We use fabric, organic mulches, manual removal, and compost top-dress—no herbicides.

• Q: What seasonal window is best?
  A: Install any time soil isn’t frozen. Fall and spring are ideal for testing function through wet periods; summer installs are fine if irrigation is managed.
