Kennec Completes Design and Construction Management of California's
First Landslide Repair Using TDA!
In September of 2007, the CIWMB in partnership with the Mendocino County of Public Works, successfully completed the first TDA slide repair project in California. The completed section of Marina Drive will no longer be a yearly maintenance cost and pending road failure for the county. KENNEC participated by developing the design and performing the Construction management of the project. This type of design is unique for California and holds promise as a new cost effective technique for permanently repairing road failures in the California hills.

Kennec Understands TDA! The California Integrated Waste Management Board (CIWMB) with the help of KENNEC and Dr. Dana Humphrey are implementing Tire Derived Aggregate (TDA) applications in California. Download the CIWMB Brochure. Current Projects involving the use of recycled tires are retaining wall construction in Riverside California, and slide repairs in Humboldt, Mendocino, and Sonoma Counties. From the community of Kneeland in Humboldt County to the City of Riverside, KENNEC is providing Design and Geotechnical services, Construction Management, Internet based Information and Collaboration Software, and coordination efforts to the Board for their program and during the projects. KENNEC proudly helped coordinate and manage the construction of the most recent retaining wall TDA project in Riverside County (Wall 207). KENNEC worked with Dr. Humphrey, the CIWMB, and CalTrans to complete this project. Included in the project was installation of various sensors in the wall that are continuously monitoring and recording data, which is then downloaded via telemetry. With the completion of our Internet based information/education project, we will be able to view the data from this and other projects online, in "real time".
