DPWH flood control projects in Santiago

The government’s Sumbong sa Pangulo portal lists 16 flood control projects in Santiago, with a combined contract cost of ₱976M, completed between 2022 and 2024.

The project list the government published in August 2025, when the flood control scandal broke. Approved contract records: project counts and contract costs only. A project’s location is not a finding of wrongdoing, and this list does not mark any project as ghost or substandard. A province’s figures include the cities inside it.
