West Seattle Add Gravel to Swale
Homeowner’s Issue
West Seattle yards sit on a mix of glacial till, compacted urban fill, and pockets of sandy loam—conditions that make surface runoff unpredictable. Winters bring long stretches of rain and short, hard storms; low spots and driveway swales underperform, creating standing water, muddy edges, and eroded channels. On hillier blocks near Admiral and on gentle slopes toward Alki and Lincoln Park, swales can funnel water too fast, carving ruts and carrying sediment toward storm drains. Shady north-facing slopes promote moss and slow infiltration, while sunnier slopes dry quicker but still need stable surfaces to prevent erosion.
HOAs and neighbors notice standing water fast—curb appeal drops and muddy walkways become safety hazards. Many West Seattle homes have limited access for big equipment, narrow alleys, and steep driveways that complicate repairs. City rules favor sustainable measures and discourage chemical use; adding properly sized, clean gravel and selective native plantings is an accepted, low-impact fix. A well-executed gravel swale reduces erosion, filters sediment, and keeps water moving where the city wants it—without heavy infrastructure or long shut-downs.
Our Quality Service
We assess the swale geometry, soil, and downstream connections before any work. For small residential swales we use hand tools, wheelbarrows, and a plate compactor when needed; larger runs may require a tracked mini-excavator if site access allows. Typical timeline: a half- to full-day for a 10–30 ft swale; one to two days for more complex, slope-prone jobs. We never use herbicides—only mechanical, organic weed control and native plantings for stabilization.
Local know-how: we size gravel to balance infiltration and stability for West Seattle’s rain patterns, account for slope and potential salt exposure near the waterfront, and recommend native sedges or bunchgrasses where planting helps filtration. Work includes clean-up and either haul-away or green‑bin disposal per your preference. Benefits: safer walkways, improved curb appeal, reduced erosion, and less maintenance through the wet season.
What’s Included
- Onsite assessment of swale slope, soil, and outlet.
- Clearing of leaves, debris, and surface weeds by hand.
- Minor reshaping of the swale profile for correct flow.
- Installation of clean, washed gravel to specified depth and width.
- Light compaction and final grading to ensure stable surface.
- Final inspection and siting advice for future maintenance.
Options / Upgrades
- Landscape fabric under gravel for heavy weed pressure (organic option available).
- Native plant plugs (sedges, Juncus, Carex) to improve filtration.
- Organic weed control treatments (mechanical + vinegar-based spot control).
- Haul-away to dump vs. sorting for City green‑bin/composting (we follow Seattle compost rules).
Before & After / Expectations
Expect noise from compactors or small machinery on larger jobs and a bit of mud while we excavate. We’ll protect lawn edges, gates, and hardscape, and stage gravel to minimize driveway disruption. Debris can go in your green bin if compostable; concrete or excess rock may be hauled away (fees disclosed up front).
After: the swale should show immediate improvement—no standing puddles after normal rain events and less side erosion. Maintenance: check for sediment build-up and rake gravel level after heavy storms (annually or after major events). Watering for plantings is minimal after establishment; in dry summers hand-water native plugs for first two seasons. Moss and ivy on shady slopes need mechanical removal and periodic inspection.
FAQs
Q: How deep and wide will the gravel layer be?
A: Typically 1–3 inches of washed gravel over a re-shaped base; width set to existing swale or to design specs for flow capacity.
Q: Will this stop all flooding?
A: No single fix guarantees zero flooding during extreme storms. Gravel improves drainage, reduces pooling, and prevents erosion for usual West Seattle rains.
Q: Can you work on steep or narrow access properties?
A: Yes. We size our approach to access constraints—hand crews for tight jobs, tracked equipment where space allows.
Q: Do you use pesticides or herbicides?
A: No. We use mechanical removal, organic spot control, landscape fabric options, and native plants to manage weeds sustainably.
