About the Project

  1. Overview
  2. Project Timeline

The slope had been sliding and failing over time. Black tarps were put into place to protect the slope from erosion and damage from rain events.

Crews removed the tarps and then cleared loose rock and soil from the slope. 

The slope was stabilized using shotcrete, an application method where a four-inch layer of concrete is sprayed onto the slope, matching its contours. Before the concrete was applied, crews installed metal bars across the slope to tie the concrete to the slope. 

Massana Construction is the project contractor. The construction cost is approximately $353,000 and is funded with County Road Funds.

Plans, specifications, and bid tabulations for this project are available through the Pierce County Procurement and Contract Services website. Access is provided by going to
