Erosion Control for Inland Empire Slopes

On Inland Empire slopes, every winter storm can carry away soil, mulch, and even plantings. Erosion not only ruins your landscape, it can undermine structures and clog drains downhill. Fortunately, several proven methods stop soil from washing away. Here is how to control erosion on a slope.

Plant deep-rooted ground covers

Living roots are the best long-term erosion control. Fast-spreading, deep-rooted plants knit the soil together and absorb runoff. Good choices for our climate include trailing rosemary, ceanothus, native grasses, and myoporum. The denser the planting, the less bare soil exposed to rain.

Use mulch and erosion netting

While new plants establish, the slope is vulnerable. Cover bare soil with a thick layer of coarse mulch or install jute or coir netting, which holds soil in place and breaks down naturally as plants fill in. Avoid fine mulch on steep slopes — it floats away.

Slow the water down

• Terracing: retaining walls or low check structures break a long slope into steps that catch water and soil.
• Swales: shallow planted channels that intercept and slow runoff.
• Dry creek beds: rock-lined paths that direct water safely downhill.

Manage runoff from above

Often erosion starts with water dumping onto the slope from a downspout, driveway, or neighbor's property. Redirecting that water with drains and proper grading addresses the root cause. Drip irrigation (not spray) on the slope itself prevents your own watering from contributing to the problem.

Frequently asked questions

What is the fastest way to stop slope erosion?

Cover bare soil immediately with mulch or erosion netting, then plant deep-rooted ground covers for long-term stability.

Do retaining walls stop erosion?

Yes — by terracing a slope into level sections, walls dramatically reduce runoff and soil loss, but they need proper drainage to work.
