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 contains the information necessary to design successful, cost-effective and sustainable erosion control treatments.
The Permanent Erosion Control Establishment specification may be used on projects with challenging slope conditions. This set of specifications and bid item ensure 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 offers tools to assist in the design of sustainable erosion controls on project sites. Click here to download a copy of the Erosion Control Technical Guide.
The table below provides a general overview of various erosion control Best Management Practices (BMPs). Select the erosion control treatment(s) best suited to address deficiencies identified with a project.
Click on the hyper-link at left to obtain more specific information regarding a BMP.
Treatments rated highly beneficial for infiltration include those that slow runoff, improve soil structure and open up the soil texture to increase infiltration of stormwater rather than encourage runoff. Treatments that notably improve infiltration include incorporate materials, roughen soil and preserve existingl topsoil.

Generally Not Recommended
N/A Not Applicable - this treatment is typically not used in these conditions.
When selecting and combining various erosion control treatments, it is important, foremost, to clearly identify "success." Success is dependent upon site specific conditions, however, a successful erosion control treatment will sustainably address three specific areas - soils, water, and vegetation.
The goal of effective erosion control is twofold:
The Natural Environment As "Success"
In the natural environment, these goals are fulfilled by vegetation, mulch/duff and porous soils. Vegetation protects the soil from raindrop impact and surface erosion. Healthy, porous soils infiltrate stormwater, reduce runoff, and retain water necessary to sustain healthy vegetation. The mulch/duff layer protects the soil surface from erosion, provides nutrients to sustain vegetation, and feeds microorganisms that contribute to a well draining soil structure.
