Location: Bellevue, WA

OCI was responsible for the removal of an asbestos concrete waterline suspended 5 feet above Kelsey Creek. The design required coordination with the fish window, evaluation of impacts to the stream, and addressing limited access to the site. OCI performed site visits, completed the design for the removal and streambank restoration, and documented the process and requirements in a technical memorandum. OCI also prepared plan drawings and JARPA permitting plan set. The team also provided permitting, engineer’s estimate, erosion and sediment control design, and utility coordination. The removal and restoration took place in the summer of 2012.
