Flood Mitigation Efforts

Project Money Goes 'Down the Drain' | October 2013

The state Motor Pool lost 150 vehicles and thousands of gallons of fuel in January 2012 when a flash flood caused damage in many areas of Salem. But Fleet & Parking Services recently completed an improvement project at the Motor Pool and staff report they are ready should Mother Nature put on a repeat performance.

Fleet & Parking Services staff; "We're ready for a flood."
By implementing new drainage strategies, the Airport Road property can now deal with an additional 250,000 gallons of water per minute. “In other words,” said manager Brian King, “we can now handle the same amount of water that would fill an Olympic-sized swimming pool in three minutes.” Guess they won't need that kayak. 

Several serious downpours in September gave the Motor Pool its first big wet test. The Motor Pool property is low to the water table and the property has a natural slope that lends itself to standing water. And then there’s Shelton Ditch, a creek that runs between Publishing & Distribution and the Motor Pool. But the September rains were no match for newly enlarged ditches in and around the property, which never filled to the top, or two new bio-swells (see photo below). 
 
Even the fuel tanks stayed high and dry now that Motor Pool installed a new inlet system that prohibits water from getting in. Also, the new valves are compliant with current EPA code, another benefit.

Fleet & Parking Services’ recent improvement project also included installation of LED lights on the back lot and park-and-ride lot, reducing energy consumption, saving $30,000 each biennium, and providing more light and increased safety to customers.
