Santa Cruz Route 17 Drainage Improvement

ongoing

The project proposes to replace or repair 13 drainage culverts between post miles 0.0 and 12.5 on State Route 17 in Santa Cruz County. Multiple culvert structures within the project limits are in various states of disrepair and, if not addressed, could lead to failure or damage to the roadway along State Route 17. The project would repair or replace culverts that have deteriorated due to age and would not construct new culverts at new locations. Additionally, improvements to drainage systems would help to minimize the discharge of sediment into the San Lorenzo River watershed. Reducing the sediment load in the receiving waters of the San Lorenzo River watershed will allow Caltrans to comply with a regulatory order called a sedimentation/siltation Total Maximum Daily Load, which is imposed and enforced by the Central Coast Regional Water Quality Control Board.
