Andrée Clark Bird Refuge Restoration
Construction of the Andrée Clark Bird Refuge Restoration is underway, and is anticipated to be complete in December 2022.
The Andrée Clark Bird Refuge is a 42-acre passive City park on East Cabrillo Boulevard that contains a shallow 32-acre brackish lake. The lake is an historic salt marsh that was once connected to Sycamore Creek. The salt marsh was dredged in the late 1920’s to provide a year-round water feature and to improve habitat for open water bird species.
Poor water quality conditions and strong odors at the lake have been problematic since the 1930s. The accumulation of nutrients, lack of flushing storm events, and drought conditions lead to low dissolved oxygen levels, cyanobacteria blooms, poor water clarity, and strong odor events.
The Creeks Division collected several years of data and evaluated of a number of potential techniques for improving water quality conditions in the Bird Refuge. A restoration plan has been developed to replace the weir gate with an improved design, construct an upstream treatment wetland at the Municipal Tennis Courts on Old Coast Highway, restore habitat around the lake with the installation of native plants and trees, and to restore dune and salt marsh habitats at the mouth of the Bird Refuge on East Beach.
