Meydenbauer Streambank Protection
Streambank Restoration Project
Bellevue WA, summer 2009
City of Bellevue WA replaced an aging sewer system adjacent to Meydenbauer creek. A sheet pile wall was driven 27 feet into soil for reinforcement for the new roadway and sewer line. Envirolok was utilized to face the stream side of the sheet pile wall and prevent soil loss thru erosion. Envirolok also restored the biological function of the streambank, keeping the city in compliance with no net loss of biological function mandated by Washington Dept of Ecology. Project Background Access was extremely limited and all construction activities had to take place in a 12 foot right away. The roadway needed to be passable at all times and Sunmark Environmental was able to complete this job it 4 working days. All equipment was brought to the site daily as were the Envirolok system and backfill material.
Installation of Envirolok Vegetated Retaining Wall System, distributed and installed by Sunmark Environmental Services. Sunmark Environmental Services has a long history of working with native vegetation for erosion control, and is a Certified Installer of the Envirolok Vegetated Retaining Wall System
