Erosion control and water pollution control are critical elements of construction and maintenance work. Engineers, inspectors and maintenance crews receive training on the design and installation of Best Management Practices and regulations pertaining to water quality.
Mulching is the simplest, least expensive and often most effective means of protecting soil surfaces against erosion and preventing sedimentation into streams.
More information about Best Management Practices for erosion control can be found at:
- San Mateo County Watershed Protection Standards
- Start at the Source, Bay Area Stormwater Management Agencies Association
- Best Management Practices page on the STOPPP website
- Erosion and Sediment Control Field Manual, by San Francisco Bay Regional Water Quality Control Board and distributed by the Association of Bay Area Governments ($30.00)
- Guidelines for Protecting Aquatic Habitat and Salmon Fisheries for County Road Maintenance, by FishNet4C
