Post-project monitoring data shows that the Cooley Landing Salt Pond breached-levee restoration is meeting the established project objectives by creating diverse habitat, which is evolving towards a mature marsh system. Engineered design elements, including breach channel training berms and levee borrow ditch blocks, have encouraged the re-occupation of the historic tidal channel footprint and prevented the development of primary channels in the artificial borrow ditch. The restored marshplain has aggraded by a maximum of 0.6 to 0.8 ft in the last two years and vegetated with pickleweed. The breaches provide adequate tidal drainage and low tide drainage is controlled by the elevation of the rapidly eroding outboard mudflat channels.
