Pacheco Marsh

Overview

Otherwise known as the North Reach of Lower Walnut Creek, Pacheco Marsh is a 122 acre former tidal marsh located adjacent to the mouth of Lower Walnut Creek. This portion of the restoration project is a partnership between the John Muir Land Trust and the Flood Control District.

undefined Opens in new windowThe partners’ goal for the site is to restore the degraded wetland habitat to historic tidal conditions and maximize habitat values while for allowing for compatible recreational uses.

The Flood Control District is focusing on the habitat restoration as part of the greater Lower Walnut Creek Restoration project, while the Land Trust is focusing on providing passive recreation opportunities (such as bird watching) and long term stewardship.  More Pacheco Marsh information can be found on the John Muir Land Trust's Pacheco Marsh website.

 

History

Pacheco Marsh historically was part of a broad marshland at the shoreline of Suisun Bay that was nurtured by periodic overflows from Walnut Creek. In more recent times, the Pacheco Marsh has been diked and drained, and then partially filled with dredge spoils. In the 1950s, a large sanitary sewer outfall and access road was constructed down the middle of the parcel, and the parcel at the north end of Pacheco Marsh was used to offload sand mined in the bay. In the 1980s, a 39 lot industrial subdivision was proposed to be built on the marsh which would have obliterated any remaining habitat value.

In the 1990s, the parcel owners defaulted on their property taxes, and in 2001, the parcel was acquired by the partners at a tax default sale. Soon afterwards, a feasibility-level restoration plan was prepared  and portions of this plan have been incorporated in the Lower Walnut Creek Restoration plans. 

Future

The partners are excited to restore the habitat of Pacheco Marsh and to open it up to the public.  To access Pacheco Marsh now, please sign up for a tour.
