This project restored 28 acres of wildlife habitat to native wetland, transitional and scrub plant communities along 1.7 miles of Upper Sulphur Creek, including removal of 3,600 feet of concrete channel to create a wider, soft-bottom stream channel.

The goal of this project was to enable the City of Laguna Niguel to restore approximately 7,900 linear feet of stream corridor of the Upper Sulphur Creek, which is a major tributary into Aliso Creek that drains into the ocean. The project included continued monitoring of water flow and quality parameters, establishment and diversity of plant communities and colonization by native fauna and migratory birds. The restoration led to more natural downstream functions in this coastal watershed and improved water quality.
