Document Description
The California Department of Transportation (Caltrans) is proposing the State Route (SR) 116 Slide Repair Project (Project) to install a soldier pile retaining wall with tiebacks and upgrade the drainage system at postmile (PM) 9.55, between the unincorporated communities of Guerneville and Monte Rio in Sonoma County (Figure 1-1). The Project is considered a Major Damage (Permanent Restoration) project. During multiple storm events the slope between the westbound lane and Old Monte Rio Road has slipped, causing mud and debris to spill onto SR 116. The existing slide continues to move during precipitation events and requires frequent maintenance to keep the highway open.
