UPDATED: MAY 21, 2019

Community Engagement

Parks staff led an educational walk at McInnis Marsh on Tuesday, May 21, 2019 from 10am to 1pm, speaking about restoration opportunities along the lower sections of Las Gallinas and Miller Creeks. James Raives and Sarah Richards, who are heading up this project, discussed the vision for the McInnis Marsh restoration. Naturalist Shannon Burke led a walk along the levees for a closer look at the project area and the animals that will benefit.  

Overview

The McInnis Marsh project proposes to restore subtidal and intertidal habitat at an 180-acre area of diked wetlands within McInnis Park, home to protected species including black rail, Ridgway's rail, and salt marsh harvest mouse. It will also help protect McInnis Park golf course from sea level rise and maintain the San Francisco Bay Trail connection to Las Gallinas Valley Sanitary District..

Through a grant from the California Department of Fish and Wildlife and Measure A funding, Marin County Parks has hired Environmental Science Associates (ESA) to design the project and prepare plans and specifications. ESA has prepared an initial draft of the project designs, which is currently under review. We also hired Prunuske Chatham Inc. to prepare an environmental assessment of the project.

Proposed Features

  • Lower levees that separate the marsh from Miller Creek, Gallinas Creek, and San Pablo Bay.
  • Breach Miller and Gallinas Creeks to allow flow into the marsh at lower tides..
  • Construct an ecotone levee between McInnis Park Golf Course and the marsh.
  • Install a new Bay Trail connection to Las Gallinas Valley Sanitary District property.
