Trestle Glen Boulevard Fire Flow Improvement Project

Marin Municipal Water District is scheduled to begin a fire water line improvement project on the entire length of Trestle Glen Boulevard on October 5, 2017. The project consists of trenching in the street, replacing underground water lines and restoration of the street. One lane of Trestle Glen Boulevard will be shut down with alternating one-way traffic controls between the hours of 9AM - 3PM. The work is estimated to be completed in one month, but weather delays and other unforeseen circumstances may extend construction work further.

Sugarloaf Drive Landslide Repair Project

Over the last winter, a landslide occurred on an open space parcel owned by the Town of Tiburon near 98 Sugarloaf Drive. The project has been separated into three phases:

  1. Installation of drilled piers and a concrete grade beam
  2. Relocation of utilities located within the landslide area
  3. Reconstruction of the hillside and placement of large boulders
The first phase of the slide repair project has been completed and the next two phases are projected to begin as soon as mid to late-August. Work on the second phase will be performed by the respective utilities (PG&E and AT&T) and may result in temporary interruptions to utility service while the work occurs. The third phase is projected to begin in early September and will be performed by a contractor working for the Town of Tiburon. 

The project consists of a landslide repair on a steeply sloping area in a somewhat inaccessible portion of Town of Tiburon open space adjacent to residences. The project involves the installation of a slope stabilization cascade buttress in a debris slide area, which will include minor grading to remove loose material and allow the placement of large boulders with a keyway system for permanent stabilization of the debris slide. The area of stabilization work is approximately 50 feet long by 20 feet wide. It is estimated that work shall be completed within 35 working days from the start of the project. 

During the third phase of the project where the large boulders are placed, it is expected that there will be some delays to traffic and the potential for road closures near 98 Sugarloaf Drive. A large crane or excavator will be required to lower boulders into place and it is anticipated that the equipment will fill the entire width of the street. Pre-notification mailers or doorhangers will be distributed once the project gets closer to starting to notify residents when this work will be scheduled. Access for emergency vehicles will always be maintained and close coordination will be done with the Tiburon Police Department and Tiburon Fire Protection District.
