Ballona Wetlands Restoration

Despite changes caused by human activity over the last century, including oil extraction and dredge spoils from marina construction, the Ballona Wetlands continue to provide habitat for threatened and endangered species while providing scenic open space in the heart of Los Angeles County. When California's Department of Fish and Game took title to the historic wetlands and a section of the channel of Ballona Creek, restoration planning began.

ESA worked to refine a series of alternatives for habitat restoration, flood management, and public access based on extensive stakeholder input and scientific review. The alternatives provide a long-term vision for achieving project objectives, incorporating phasing and adaptive management. ESA addressed planning for biology, flood management, infrastructure, hydrodynamics, water quality, public access, and cost estimating. Our team provided technical support for the environmental impact analysis for the two preferred restoration alternatives.

ESA worked to restore and enhance 600 acres of native estuarine and upland habitats along both sides of the Ballona Creek channel in Los Angeles County. Together with restoring estuarine functions, the project provides public access and recreational opportunities consistent with the site's resources.
