Document Description
A section of SR 299 is failing due to subsurface water flow under the highway. Caltrans will place a 200' underdrain on the uphill side of the highway to intercept subsurface water. Horizontal drains will be placed on the uphill side of the highway and slope indicators will be installed to determine the elevation of the slip plane. The highway will be repaired to preserve the ride. Excess material will be disposed at the Slattery Pond disposal site. During construction, all work will comply with the Caltrans Statewide Storm Water Management Plan to ensure sediment does not reach the adjacent creek. Adequate erosion control measures will be included as part of the completed project to protect slopes.
