White Meadows Road Slip Out

This project involved a landslide affecting a 140 ft section of county road within steep terrain at a 7% road grade.  Blackburn Consulting conducted a site investigation and evaluated repair options, including reconstructed embankment; tie-back soldier pile wall; roadway realignment; soil nail wall; and MSE retaining wall.  The MSE wall was concluded to be most straightforward and cost-effective.  In cooperation with county engineering staff, we completed project plans and specifications.  The county constructed the wall with its own crews while we provided construction management and materials testing.  The project was successfully completed on an accelerated schedule and represents a model for future cooperation to achieve substantial cost and time savings.
