Erosion control and slope protection in Evergreen, Colorado

When water has no choice but to run downhill, the slope takes the hit. We protect it with rock, erosion control blankets, wattles and revegetation, designed and engineered for your site.

Which slopes need protecting

The ones that erode easily, and the ones under the direct influence of drainage: slopes that will receive runoff, or where water is channeled and has nowhere to go but downhill.

There are many ways to go about it. As with any challenge, proper design and engineering is the best approach.

Drainage first, then the slope

The first step is controlling the water on the driving surface. Once that water is directed to specific spots, those spots have to be protected.

Skip that second step, and the slopes receiving the water erode even faster than before. That's why we treat drainage and erosion control as one job, not two.

How we protect an eroding slope

On slopes that will erode easily, revegetation is the long-term fix. The blanket protects the slope while the seed takes hold.

  1. Organic soil base

    A base layer of organic soil, so the seed has the right conditions to germinate.

  2. The right seed mix

    Chosen for the site conditions, which vary across the Front Range, and for the result you want: green grass or a native mix with wildflowers.

  3. Seeding

    Hand spread and raked in, or applied with a hydroseeder, depending on the slope and the size of the area.

  4. Erosion control blanket

    Blankets that completely cover the hillside, protecting the seed and holding the soil while it germinates. They break down over time.

  5. Watering

    Proper watering during germination is very important. It's what turns seed into a slope that holds.

Rock and riprap

Where water is channeled, rock armors the ground so fast water can't cut it away.

Straw wattles

Long tubes of straw-like material placed in drainages to slow the water before it ruts the hillside.

Hydroseeding

Seed sprayed on in a slurry, a practical way to cover larger or steeper slopes evenly.

Erosion control questions

Do you do hydroseeding?

Yes. Depending on the slope and the size of the area, we either hand spread and rake in the seed or apply it with a hydroseeder.

What kind of seed do you use?

It depends on the site and what you want. Conditions vary across the Front Range, so the seed mix is chosen for your slope. Some people want green grass; others want a native mix with wildflowers.

Does the erosion control blanket have to be removed?

No. The blankets break down over time, after they've protected the seed and held the soil while it germinates.

Why fix the drainage before the slope?

Because slopes erode fastest where water is directed at them. We control the water on the driveway first, then protect the spots where that water goes.

Got a slope that's washing away?

Text a few photos of the slope and where the water comes from, and we will tell you what to expect.
