City of Portland, Water Bureau – Walker Creek Fish Passage Culvert – Environmental – Less than $5 Million – Project of the Year 2011
Consultant: Murray, Smith & Associates, Inc.
Contractor: Moore Excavation, Inc.
– Subcontractor: Ferrari Enterprises, Inc.
This project re-established fish passage to Walker Creek in the Bull Run watershed. The new culvert is 58-inches tall and 18-feet wide with an open bottom to mimic natural streambed conditions. It was installed directly below two Portland water Bureau supply conduits that provide potable water to 850,000 customers, so special care was taken to support the conduits and keep them operational during construction.
