Early to mid 2024: Complaints begin

Residents and local governments report flood control projects that are unfinished, poorly built, or not visible at all — despite large budgets under the administration of President Ferdinand Marcos Jr. The Commission on Audit starts flagging irregularities in Department of Public Works and Highways projects, including missing structures, relocated works, and payments for flood controls that already existed, especially in Bulacan.

Late 2025: Arrests and political fallout

27 November 2025: Lawmakers named
