About The Project
In 1974, led by an innovative Board of Directors, MVSD became the first Wastewater Treatment Plant on the West Coast to utilize treated wastewater for wetland creation. The resulting Moorhen Marsh saved the District’s rate payers millions of dollars by eliminating the need for a deep water outfall while establishing a 21-acre habitat that benefits numerous aquatic and terrestrial species. Almost 40 years later, MVSD produced the Moorhen Marsh Management Plan which calls for significant improvements to this historical wetland.
Pre-construction activities for Phase A including pond dewatering, fish rescue, vegetation cutting, and wildlife exclusion fence installation will run between January and April 2017. The Phase A improvements will be constructed between mid-June and November of 2017. As proposed, the Phase B timeline in 2018 will mimic the Phase A schedule.
During Phase A construction, Moorhen Marsh will be closed to the public from mid-June through November 2017. Phase B construction will likely close the marsh mid-May through November 2018.

MVSD regrets any inconvenience to our wetland visitors that may be caused by the Project. Please be patient as we work to improve this important wetland for wildlife and human visitors alike.
