Why It Matters
Both chambers of the 119th Congress are advancing competing Water Resources Development Act of 2026 (WRDA 2026) bills that include provisions designed to protect authorized water infrastructure projects from executive branch pauses and cancellations, according to a Congressional Research Service (CRS) report on Army Corps provisions in the legislation. The report identifies a central tension: the Trump administration has taken a series of unilateral actions affecting the U.S. Army Corps of Engineers (USACE), and Congress is now using the biennial WRDA process to push back.
In an October 17, 2025, social media post, Office of Management and Budget Director Russell Vought announced that USACE would immediately pause more than $11 billion in civil works projects and consider them for cancellation, citing lower-priority status, with projects in New York, San Francisco, Boston, and Baltimore among those named. Congress responded by including language in the fiscal year 2026 appropriations explanatory statement prohibiting USACE from pausing or terminating any project without providing prior written notice and justification to the appropriations committees.
The Big Picture
Two WRDA 2026 bills are moving through the 119th Congress: H.R. 9497, passed by the full House in September, and S. 4949, reported in July by the Senate Committee on Environment and Public Works. CRS notes that enacted WRDAs typically draw on provisions from both chambers' bills, meaning the final version will likely be a negotiated blend.
In August 2025, USACE paused completion of final feasibility reports involving nonstructural flood risk measures "at scale," with a March 2026 memo identifying only certain pilot projects to proceed. The Senate bill's Section 1118(b) would prohibit termination of the National Nonstructural Committee without congressional authorization, while the House bill's Section 132 would express a sense of Congress that nonstructural and structural features deserve equal consideration.
An October 15, 2025, memorandum required that all USACE legislative affairs activities be coordinated with the Office of the Assistant Secretary of War (Legislative Affairs) before any legislative engagements or responses to congressional requests. H.R. 9497's Section 135 would direct USACE to provide information and technical assistance expeditiously, while S. 4949's Section 1104 would require written responses within 30 days of a member's request.
On project delivery, H.R. 9497 would replace existing federal cost and time limits for feasibility studies with guidance and study-specific deadlines, while S. 4949 would allow a lower level of design maturity if sufficient for required cost estimates. The Senate bill would also require categorical exclusions from National Environmental Policy Act (NEPA) documentation for actions with federal project costs less than $50 million carried out under environmental infrastructure assistance authorities or continuing authorities programs.
The Bottom Line
The two bills have yet to be reconciled, and the final provisions of a potential enacted Water Resources Development Act of 2026 may vary from the contents of the bills as they currently stand. Whether Congress can codify durable guardrails on executive discretion over USACE funding flows, or whether the final WRDA 2026 softens those constraints in conference, is the central question as the bills move toward a potential Senate floor vote.
