Durum

The Marina Fire burned 654 acres of steep slopes between its ignition on June 24, 2016 and its containment on July 7, 2016.  The fire was named for its proximity to the nearby old marina on Mono Lake. Prior to the fire, Caltrans had programmed a phased rockfall mitigation project to address rockfall originating from six cut slopes along US 395 from post mile 53.2 to 53.7.

Açıklama

In Mono County, California temporary, flexible rockfall fences were installed to provide rockfall protection to US 395. 

Two Geobrugg flexible rockfall fences, 2,000 linear feet of GBE-500A-R (3 m height) and 1,500 linear feet of model GBE-500A-R (4 m height) were recommended and installed.

A unique aspect of this project was the uncertain location of a critical utility and design modifications that allowed the rapid installation of the fence posts while minimizing risk to the utility. 

Subsequent to the Marina Fire, this section of roadway experienced rockfall events from source areas outside the Caltrans right of way, and resulted in a need for rapid mitigation of the increased rockfall.
