Shoreline Slope Stabilization Services

Hey Shoreline residents! If your property has steep slopes, especially with those clay soils and our infamous winter rains, you know how quickly things can go downhill—literally! When water has its way, it can wreak havoc on your landscape, but don’t sweat it! At Neat & Tidy Landscaping, we’re all about drainage solutions, smart plant choices, and solid structures to keep your hillside intact and ready for all your outdoor activities.


What’s the Problem?

Here are some of the common challenges you might be facing:

  • Seasonal slumps, rills, or ugly scars left after heavy storms.
  • Bare slopes that only seem to attract weeds and lose precious mulch rather than develop strong roots.
  • Downspouts dumping water right onto your slope, creating mini rivers.
  • Old timber edging or crumbling rocks that are clearly on their way out.
  • Temporary fixes like fabric and bark that wash away in a heartbeat.

What We Build (function first, aesthetics second)

Our focus is on creating solutions that not only look good but work effectively! Here’s our game plan:

  • Drainage Controls — We set up intercept swales, French drains, dispersion trenches, splash pads, and safe outlets to efficiently redirect water flow.
  • Erosion-Control Surfaces — We use jute/coconut (coir) netting, straw wattles, and coir logs to slow down and spread out water strategically.
  • Vegetated Stabilization — Our team plants deep-rooted, native Pacific Northwest shrubs and groundcovers arranged in a grid pattern, along with live stakes in wetter areas for extra stability.
  • Rockeries & Small Retaining Walls — We reconstruct gravity rockeries and build low walls (under 4 feet) with proper drainage, fabric separation, and weep/pipe systems for durability.
  • Terracing & Access Paths — We create landings, hillside steps, and safe service paths to help you easily maintain your bank.

Just a heads-up: if you need a tall retaining wall or live in an ECA (Environmentally Critical Area), you may require a geotechnical engineer and permits. No worries—we’ll help you navigate that early on!


Our Method (why it actually holds)

Here’s how we ensure your slope stays put:

  1. Assess Water & Soil — We examine shot grades, soil types, existing seeps, and water contributions from neighboring properties.
  2. Control Water Inputs — We divert roof water into solid piping and a legal outlet while stopping sheet flow at the top of your slope.
  3. Stabilize the Surface — Coir/jute and wattles are placed on contour, with immediate planting through the netting.
  4. Planting for Stability — We use dense, layered natives like salal, evergreen huckleberry, kinnikinnick, oceanspray, and deer ferns planted close together for maximum impact.
  5. Right-Sized Structures — We construct rockeries, add short tiers, or build 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!

Quick Specs We Aim For

  • Netting: 7–8 oz coir/jute pinned every 18–24 inches; overlaps 6–12 inches for extra security.
  • Wattles/Coir Logs: Positioned on contour 10–20 feet apart vertically (depending on slope) and secured 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 wetter areas.
  • Mulch: 2–3 inches of fine bark or wood chips under the netting on steep sections; avoid loose rock mulch on steep 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 charge—somewhere you won’t appreciate.
  • Fabric on bare clay topped with bark is not stabilization; it’s just a slip layer waiting to fail.
  • Removing large trees can destabilize soils; pruning or underplanting is often a smarter choice.
  • Big walls need proper design; we won’t just stack materials and cross our fingers.

Our Annual Maintenance Plan

To keep your slope looking sharp, we offer:

  • Storm Season Checks — We inspect wattles, pins, and inlets after the first big rains of fall.
  • Vegetation Establishment — We hand-water deep roots during the first year and spot-irrigate those hot, south-facing areas.
  • Weed & Invasive Control — We keep an eye out for blackberries and ivy to ensure a healthy native canopy.
  • Edge & Access Upkeep — We maintain paths and steps to ensure safe access to all areas of your landscape.

We’re all about low-maintenance landscaping. Our aim 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 tidy-ups.
  • Bi-Monthly — Recommended for active slopes, new installations, or heavy water inputs.

(Fresh builds often start monthly for 60–90 days, 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 away from plant stems.
  • Cutting back and filling in plants to achieve the desired density.
  • Providing photo updates and a simple slope log so you can track trends.

Why Annual Maintenance Matters

  • Prevents rills from developing 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 identifying 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.
