Mark Merkelbach worked with the SWA Laguna Beach office to provide hydraulic and ecological design of the  Baxi Island in Changsha, China. This involved modeling river water surface elevations which were used as a basis for design of permeable island levees, multiple wetland complexes, and habitat wood structures. This project was recently recognized as a ULI Urban Open Space Award Finalist.
