OCI was responsible for TESC Plan Sheets and TESC Plan Narrative to add one auxiliary lane on northbound I-405 from NE 195th Street to SR 527. The project also included improvement to storm drainage resulting from the road widening exercise. OCI utilized MGSFlood to size temporary sediment ponds and designed other TESC BMPs to help prevent, control, and handle sediment from exiting the work zone and entering the existing storm drainage system and waters of the State. OCI regularly attended Task Force meetings as required, assisted in the design of an asphalt grind plane, and reviewed spread calculations.
