Los Angeles County On-Call Environmental Services

Supporting Sustainable Water Supplies and Healthy Watersheds

Los Angeles County Department of Public Works provides sustainable water supplies and healthy watersheds while reducing flood risk for more than 10 million people in Los Angeles County. Since 1997, through on-call contracts, our Environmental Group has supported the County with various water resources projects by providing environmental review and biological and cultural support services.

The award-winning Santa Anita Oak Woodland Project was one of many projects we’ve worked on with the County. Projects have included maintenance, repair, and construction of channels/basins, streams, dams, bridges, and other facilities.
