San Joaquin Marsh Reserve Water Conveyance and Drainage Improvement
MND - Mitigated Negative Declaration
Present Land Use
Open Space - General in 2007 LRDP
The Project would improve the long-term water management and habitat value of the San Joaquin Marsh Reserve (Marsh Reserve) located in City of Irvine, Orange County, California. The Marsh Reserve is owned by the University of California (UC) and managed by the UC Natural Reserve System (NRS) and by the University of California, Irvine (UCI). The Project proposes new- and repair of- existing hydrology and water quality infrastructure to better manage flows within the Marsh Reserve.
Design Goal 1 proposes infrastructure establishment and/or modifications that anticipate impacts of climate change (e.g., drought, flooding, and sea level rise). Design Goal 2 focuses on water sourcing, treatment, and measurement (from Irvine Ranch Water District (IRWD) or San Diego Creek). Construction is anticipated to take approximately 8 to 10 months total and may occur in two phases, likely one phase for Design Goal 1 and one phase for Design Goal 2. The Marsh Reserve would continue to function as a preservation area during and after construction.
