Marin County Open Space District Region 6 Trail Designation Process

In 2015, the Marin County Open Space District (MCOSD) began a collaborative public process to formally designate a road and trail system in county preserves. This process is taking place on a region-by-region basis. Regions 1-5 have been designated, while designation is currently active for Region 6 (Old Saint Hilary’s, Tiburon Ridge, and Ring Mountain preserves). A goal of the process is to create a designation map. A designated road or trail is one that appears on an official MCOSD preserve map and is marked with signs.

On Wednesday, November 17, the Marin County Open Space District (MCOSD) hosted an online community workshop on designating a formal road and trail system in Region 6, which includes Ring Mountain and Old St. Hilary’s preserves. Principal Natural Resources Planner Jon Campo described the planning process and draft concept maps, and outlined opportunities for public comment. Attendees participated in a question-and-answer session.

Concept Design Alternatives for a Beach Restoration Project at Greenwood Beach System (Blackie's Pasture), Tiburon, Marin County

Beach Restoration 1
Beach Restoration 2

The project aims to demonstrate that bay beaches as a living shoreline design approach are a viable alternative to riprap and seawalls. Living shoreline techniques reinforce the shoreline and minimize coastal erosion, while restoring natural habitats for estuarine and coastal organisms. Through strategic placement of native vegetation and natural materials such as sand, gravel, and cobble, bay beaches can protect tidal marshes behind them from further erosion. Building on preliminary designs funded through a partnership between the Marin Community Foundation and California State Coastal Conservancy, the project will develop near-final designs for a gravel beach that will provide nature-based shoreline protection and enhance valuable coarse-grained beach habitat. The goal of the project is to complete CEQA documentation and permit applications and be ready for final design and implementation of the gravel beach design.

As part of Blackie’s Pasture Beach Restoration Project, the County of Marin will be placing sand tracers at four different locations at the site to assess how the sediment moves around during bigger storm events.  They will need to place some fluorescent dye at those locations and locate with a UV flashlight for analysis.  The dye is environmentally safe and there may some initial visibility but county staff will try to minimize impact as much as possible.
