Welcome to the Caltrans Erosion Control Toolbox, a one-stop reference for erosion control standards and guidance. The purpose of this site is to provide Caltrans Landscape Architects with a single location that provides access to the information necessary to design successful, effective and cost efficient erosion control treatments.
The new Permanent Erosion Control Establishment specification may be used on projects with challenging slope conditions. This set of specifications ensures that a Contractor will be available during the Erosion Control Establishment period to perform the repair work required to ensure the establishment of healthy, sustainable, long-term vegetation. For guidance on how to use this set of specifications, please click here.
The Caltrans Technical Guide to Erosion Control Treatment, first presented in the "Key Concepts" Erosion Control training is now available online. Click here to download a copy of the Erosion Control Technical Guide. Please note that the "BMP Data Sheets" formerly included in the Technical Guide are available by clicking on the underlined links below.
The table below provides a general overview of various erosion control Best Management Practices (BMPs) together with a very rough idea of cost. Select the erosion control treatment(s) most suited to meet your project deficiencies.
Click on the hyper-link at left to obtain more specific information regarding a BMP.
May or may not be recommended based on site conditions. Check with your Geotechnical engineer.
Generally Not Recommended
N/A Not Applicable - this treatment is typically not used in these conditions.
Treatments rated highly beneficial for soil cover include those that provide protection from raindrop impact and splash erosion. Treatments that provide good cover include loose mulches such as bark and compost, fiber included as part of hydroseeding, and rolled erosion control nets and blankets.
Treatments rated highly beneficial for soil health include those that improve soil texture, soil structure, fertility, and soil microbiology. Treatments that notably improve soil health include compost incorporate, duff, and reusing local topsoil.
Treatments rated highly beneficial for infiltration include those that slow runoff, improve soil structure and open up the soil texture to encourage infiltration of stormwater rather than encouraging runoff. Treatments that notably improve infiltration include compost incorporate, roughen soil and reusing local topsoil.
When selecting and combining various erosion control treatments, it is important, foremost, to clearly identify "success". While the specific definition of "success" will vary depending upon specific site conditions, in general, a successful erosion control treatment will address three specific areas - soils, water, and vegetation.
The goal of effective erosion control is twofold:
In the natural environment, these goals are fulfilled by vegetation, mulch/duff, and porous soils. Vegetation and the mulch/duff layer protect the soil from raindrop impact and surface erosion. Healthy, porous soils infiltrate water reducing runoff, and provide the water necessary to sustain healthy vegetation. The mulch/duff layer protects the soil surface from erosion, provides nutrients to sustain vegetation, and feeds soil microorganisms that contribute to a well draining soil structure.
