Public Comment Period

The draft Initial Study/Mitigated Negative Declaration (IS/MND) is available for review. The public comment period is April 29 – May 31, 2019 at 5:00 p.m. The IS/MND provides information regarding the setting of the project area, the project description, analysis of potentially significant environmental impacts that could result from implementation of the proposed project, and mitigation measures to reduce potentially significant environmental impacts to a less than significant level.

Project Description

Used year-round as a recreational trail, with a lower segment accessible by emergency vehicles, the upper segment of Ponti Fire Road is geologically unstable. A section of the fire road experienced a major landslide in 2005. the proposed project was identified as a potential road to multi-use trail conversion project during the Region 3 proposed designation process in August 2016. The purpose of the proposed project is to implement the MCOSD road and Trail Management Plan to provide the public with a safe multi-use trail system to enhance to visitor experience, reduce the environmental impacts on sensitive resources by reducing sedimentation and erosion, and establish a sustainable system of roads and trails that meet design and management standards and would provide year-round access along the trail alignment.

This project is being developed in conjunction with the Marinwood Fire Department, Novato Fire Protection District, Marin County Fire Department, Marinwood Community Services District, open space neighbors, and the Marin County environmental community.
