Many hillside lots have been cleared of the natural vegetation that once stabilized the slope. To control erosion (detachment and movement of soil by wind, water or gravity), use native plants and grasses with elaborate root systems of varying depths (click here for a list of recommended native plants). Deep root systems allow native plants to survive in severe drought conditions as well as hold the soil in place.

Slopes and stream banks need special attention. Slopes that are too steep (greater than a 3:1 ratio) inhibit plant growth, creating a bare bank that will further erode and grow steeper. Landowners should consider re-grading in order to promote bank stability. Biodegradable netting and erosion control blankets can help to stabilize slopes and prevent sediment pollution in creeks and waterways.

Before undertaking any grading or re-grading, check with the County building department to find out what permits and restrictions you will need to work with.

Before doing any streambank work, check with the California Department of Fish and Game to find out what kind of permitting is required.

Each municipality has regulations that limit the amount and time of year of grading to decrease the loss of soil and potential runoff to critical water bodies.
