Document Description
The California Department of Transportation (Caltrans) proposes an emergency Director’s Order project to address damages caused by the Tamarack Fire at five locations along State Route (SR) 89 between post miles (PM) 15.21 and 16.87, in Alpine County. The scope of work at Location 1 (PM 15.21) proposes replacing the existing 48” Corrugated Steel Pipe (CSP) with a 10’x10’ Reinforced Concrete Box culvert, excavating upstream of the culvert to restore the channel, and Rock Slope Protection (RSP) placement upstream of the inlet. At Location 2 (PM 15.65) and Location 3 (PM 15.84) RSP will be placed at the inlets and outlets. At Location 4 (PM 16.02) a new metal debris rack will be installed approximately 25’ upstream from the inlet. At Location 5 (PM 16.87) excavation will occur and RSP will be placed upstream and downstream of the existing culvert to restore the channel and control slope erosion. A Drainage Easement may be required at Location 1 and Temporary Construction Easement may be required for the work at Location 2. The purpose of the project is to restore flow of the natural channels and ensure function of the associated culverts to handle debris created from the fire. The project is needed to prevent the loss or impairment of life, property, or essential public services along this section of SR-89.
