Environmental Mitigation

Arroyo Seco Restoration Project, Pasadena, CA


    As Director of Environmental Affairs for Browning Ferris Industries, James Aidukas assembled and led a wetland and riparian mitigation team in finding a potential mitigation site in Pasadena, CA, and developed a world-class mitigation for 6 acres of wetlands and 20 acres of riparian mitigation in the Lower Arroyo Seco. Tasks included CEQA processing and approval, agency processing and approval, design, construction and final acceptance by the city county, state, and federal agencies.
    The project involved diversion of flow from a concrete-lined flood control channel into a former (pre-flood control) alluvial terrace of the arroyo, grading to recreate a stream system reminiscent of historic flow patterns, and revegetation with native plants indigenous to the area.
    This site is considered one of the best wetland mitigation projects in the Los Angeles basin by the Corps of Engineers and the County of Los Angeles.

Chatsworth Reservoir Mitigation Project, Chatsworth, CA

    As consultant to BFI, Mr. Aidukas served as the lead on a mitigation team developing a design and permitting concept for the creation of 27 acres of wetlands and 13 acres of riparian mitigation for BFI at the Chatsworth Reservoir site. This mitigation was a U.S. Army Corps of Engineers and California Fish and Game condition of approval for the BFI Sunshine Canyon city landfill expansion.  Mr. Aidukas' services included interfacing with regulatory agencies, the Department of Water and Power, the Los Angeles City Council, and the City Attorney's Offices.

Bull Creek Restoration Project, Granada Hills, CA

    Beginning in the Santa Susana Mountains and encased in a concrete flood control channel, Bull Creek travels south from Granada Hills through the San Fernando Valley.  The restoration project led by Mr. Aidukas included working with Los Angeles County Flood Control, the City of Los Angeles Valley District Office, the local city council member and area homeowners.

    A low-flow creek bed had been constructed atop the high-flow, buried concrete channel in the 1970's, but had become the neglected.  The restoration began by removing illegally dumped trash, tires, mattresses, and old appliances then removing and eradicating non-native vegetation and palm trees over a three mile stretch through Granada Hills.  The project removed impediments to the creek flow and provided the area with access to a recreational trail alongside the creek and riparian habitat.
