The drive for a new Water Resources Development Act (WRDA) is gaining momentum on Capitol Hill with the rollout of a $5-billion proposal in the House. But the bill, introduced May 23 by Transportation and Infrastructure Committee Chairman Bill Shuster (R-Pa.), focuses on only U.S. Army Corps of Engineers projects and policies. The version that a Senate committee cleared in April is much broader. It may be difficult to reconcile the two and produce a final compromise measure this year.
