Grade Stabilization Structure POLLUTANTS ADDRESSED: Nutrients and Organics, Salinity, Sediments
DESCRIPTION: Rock, alone or combined with brush or biologs, is used to control the grade and head cutting in natural and artificial channels, preventing the formation or advance of gullies.
Urban areas ADDITIONAL BENEFITS: Rocks, brush, and biologs provide habitat for small wildlife species.
LOAD REDUCTION MECHANISM: Nutrients/Organics Management- If brush or biologs are used, plants will take up excess nutrient runoff.
POTENTIAL TREATMENT AREAS: Streamside
Salinity Reduction- If brush or biologs are used, plants will take up dissolved salts from water runoff.
ALTERNATIVE MANAGEMENT MEASURES: Brush Trench Erosion Water Management Irrigation Control Fabric
Sediment Reduction – Grade stabilization structures can reduce slope erosion thus reducing the amount of sediments carried into streams.
PERMITTING REQUIREMENTS: ACOE 401 and 404 permits may be required. Contact county regional flood control district.
LAND USE CLASSIFICATION: Grazing lands Agricultural lands Cleared areas
Arid Southwest BMP
