BUILDING STRONG ® Proposed Grade Control Structure
BUILDING STRONG ® Byram’s Ford Industrial Park
BUILDING STRONG ® Stated Goals Prevent the headcutting at the battlefield location Limit maximum flood elevation to pre- project conditions Control velocity upstream to manage scour along the riverbanks
BUILDING STRONG ® Design The structure was designed to stop head- cutting and control flood elevations upstream to pre-project conditions which in turn aided in managing scour at the battlefield location and along the riverbanks by controlling velocity.
BUILDING STRONG ® Externalities Construction of the grade control structure would affect the channel upstream of this project and create pre-project conditions, i.e., flooding in areas that had not experienced flooding since the channel project began would now be flooded again.
BUILDING STRONG ®
The Value Ah Ha! The current flood levels can be maintained to limit maximum flood elevation to below pre-project conditions Grade controls can be distributed along the river rather than at a concrete waterfall Perfection Cost Functions 0% 100% Poor Value Best Value
