The Corps of Engineers, Walla Wall a District, requires a comprehensive evaluation of the radial gates at the Mill Creek Flood Control Project. The District retained HDR Engineering, Inc. to perform inspection and testing of the radial gates through Task Order No. 5 under Contract DACW68-OO-D-OOO1. The task order scope of work includes review of project information, an initial meeting and inspection, comprehensive field inspection of the radial gates, testing of gate hoist machinery, and preparation of a report. The scope of this inspection includes: Review of design, construction, maintenance and operations information provided by the District; hands-on visual inspection of accessible upstream and downstream portions of six radial gates; visual inspection of the hoists and hoist equipment; observation and testing (where possible) of gates and hoists while operating; a report including documentation of the design and operation of the gates and hoists, inspection and testing results, conclusions and recommendations. The Mill Creek Flood Control Project is located three miles east of Walla Walla, Washington on Mill Creek, a tributary to the Walla Walla River. The project includes an off-stream earthfill storage dam, two concrete-lined outlet channels, a diversion dam, intake canal headworks to Mill Creek Lake and division works on Mill Creek with an intake to the Yellow Hawk - Garrison Canal.
