Normandy Park Slope Stabilization Services

Hey, Normandy Park neighbors! If you’ve got a steep yard struggling with clay soils and the winter rains that seem to come out of nowhere, you probably know how quickly things can spiral out of control. When water gets a mind of its own, it can turn your lovely slope into a muddy disaster. That’s where we step in! At Neat & Tidy Landscaping, we specialize in drainage solutions, smart planting, and effective structures to keep your hillside intact and your outdoor space enjoyable.


What’s the Problem?

You might be facing some familiar challenges:

  • Seasonal slumps, rills, or scars left behind after heavy storms.
  • Bare slopes that only grow weeds and lose mulch instead of roots.
  • Downspouts pouring water directly onto your slope, creating mini rivers.
  • Old timber edging or failing rocks that seem to be on a downhill journey.
  • Temporary fixes like fabric and bark that wash away faster than you can say “landslide.”

What We Build (function first, aesthetics second)

We focus on practical, effective solutions, and here’s our game plan:

  • Drainage Controls — We set up intercept swales, French drains, dispersion trenches, splash pads, and safe outlets to redirect water flow away from your slope.
  • Erosion-Control Surfaces — Utilizing jute/coconut (coir) netting, straw wattles, and coir logs designed to slow and disperse water effectively.
  • Vegetated Stabilization — We plant deep-rooted, native Pacific Northwest shrubs and groundcovers in a strategic grid pattern, plus live stakes in wetter areas to promote stability.
  • Rockeries & Small Retaining Walls — We can rebuild gravity rockeries and construct low walls (under 4 feet) with proper drainage, fabric separation, and weep/pipe systems.
  • Terracing & Access Paths — We create landings, hillside steps, and safe service paths, making it easy for you to maintain your bank.

Just a heads-up: if you need a tall retaining wall or live in an ECA (Environmentally Critical Area), you’ll likely need a geotechnical engineer and permits. But don’t stress—we’ll help you navigate that early in the process!


Our Method (why it actually holds)

Here’s how we ensure your slope stays put and looks good doing it:

  1. Assess Water & Soil — We analyze shot grades, soil types, existing seeps, and contributions from neighboring properties.
  2. Control Water Inputs — We divert roof water into solid piping with a legal outlet while preventing sheet flow at the top.
  3. Stabilize the Surface — Coir/jute and wattles are placed on contour, and we plant right through the netting for immediate impact.
  4. Planting for Stability — We use dense, layered natives like salal, evergreen huckleberry, kinnikinnick, oceanspray, and deer ferns, grouped together for maximum effect.
  5. Right-Sized Structures — We build rockeries, add short tiers, or create low walls with proper bases, drainage, and geogrid as necessary.
  6. Finish for Maintenance — We ensure access steps, mower/handline edges, and mulch (2–3 inches) are securely anchored under the netting—not just floating above it.

Quick Specs We Aim For

  • Netting: 7–8 oz coir/jute pinned every 18–24 inches; overlaps 6–12 inches for maximum stability.
  • Wattles/Coir Logs: Placed on contour 10–20 feet apart vertically (depending on the slope) and staked at 3–4 feet intervals.
  • Plant Density: 1–1.5 plants per square foot for groundcover; 3–5 feet stagger for shrubs; live stakes 18–24 inches apart in wet areas.
  • Mulch: 2–3 inches of fine bark or wood chips under the netting on steep sections; avoid loose rock mulch on fast slopes.
  • Drain Fall: Target ~1% (⅛ inch per foot) minimum on conveyance lines; must daylight or disperse according to code.

Reality Checks (no sugar-coating)

Let’s keep it real, folks:

  • Water wins. If you don’t redirect it, your slope will take care of it—somewhere you won’t like.
  • Fabric on bare clay with bark thrown on top is not stabilization; it’s just a slip layer waiting to happen.
  • Removing large trees can destabilize soils; pruning or underplanting is often a better option.
  • Big walls need proper design; we won’t simply stack materials and hope for the best.

Our Annual Maintenance Plan

To keep your slope in tip-top shape, we offer:

  • Storm Season Checks — We inspect wattles, pins, and inlets after the first big fall rains.
  • Vegetation Establishment — We hand-water deep roots in the first year and spot-irrigate hotter/south-facing areas.
  • Weed & Invasive Control — We patrol for blackberries and ivy to ensure a healthy native canopy thrives.
  • Edge & Access Upkeep — We keep paths and steps safe so you can effortlessly reach those tricky spots.

We’re all about low-maintenance landscaping. Our goal is to minimize your headaches between visits and make your life easier!


Service Cadences

  • Quarterly — Perfect for fall storm prep, winter/spring checks, and summer tidying.
  • Bi-Monthly — Recommended for active slopes, new installations, or heavy water inputs.

(Fresh builds often start monthly for 60–90 days, and then we taper off.)


What Annual Maintenance Includes

  • Cleaning out inlets/outlets and flushing cleanouts where installed.
  • Re-pinning netting/wattles and replacing any that have floated away after storms.
  • Topping up mulch where it’s thin and raking it back from stems.
  • Cutting back and filling in plants to achieve density targets.
  • Providing photo updates and a simple slope log so you can track trends.

Why Annual Maintenance Matters

  • Prevents rills before they develop into gullies.
  • Keeps roots winning — dense cover outcompetes weeds and prevents erosion.
  • Protects paths & patios below the slope from damage.
  • Saves you money — small resets can avoid costly major rebuilds down the line.

How It Works

  1. Free Estimate — We can do a quick walkthrough or check out your photos for straightforward, upfront pricing.
  2. Plan & Permits — We develop a drainage plan, select materials, and create a plant palette while flagging any ECA/engineering needs.
  3. Build Day(s) — We start with drainage, then lay down stabilization layers, and finish with planting and access paths.
  4. Follow-Up — We provide a watering and establishment guide along with a tailored maintenance schedule.
