5. Project Description:

The project entails construction of a concrete retaining wall along a one-way/single-lane segment of Conzelman Road that follows a steep coastal ridge line. Erosion of the coastal bluff has threatened stability at a point along the roadway shoulder for over two decades. Approximately 12

A14 Page 2 of 2 v1 Mar2025 years ago the roadway was realigned several feet away from the bluff and a guardrail installed to protect motorists. Coastal erosion has continued, and the roadway is now partially undermined at the top of the bluff. A concrete retaining wall with deep pile foundations will be constructed to shore up the roadway prism at the erosion site. The wall will have a steel bridge rail affixed to the top. Existing steel guardrail will be adjusted to align with the bridge rail. Selected details from preliminary engineering plans are shown below.
