Flood protection exercise Oct. 17 at RiverScape MetroPark
A nearly 200-foot-long temporary floodwall will be installed at RiverScape MetroPark Wednesday morning as part of a flood protection exercise.
“When RiverScape was developed, a portion of the levee was removed,” says Jamie Johnson, MCD field operations manager. “We work with Five Rivers MetroParks to practice installing the floodwall to keep everyone current on the procedure should the river ever rise high enough to require it.”
Caps are removed from the plaza floor area, and posts are put into the openings. A crane will be used to install sections of aluminum stoplogs. The main floodwall is about 3 or 4 feet high and about 160 feet wide with another smaller opening – about 30 feet wide – west of the plaza.
“It’s unlikely that we would ever need to install the floodwall,” Johnson says. “It would take an event bigger than the Great Flood of 1913, which brought between 9 and 11 inches of rain over a 72-hour period across the entire 4,000-square-mile watershed.”
