In 1991, Ormoc City was hit by a devastating flood brought by Typhoon Uring, causing tremendous damage of 5,000 deaths, 3,000 missing and 14,000 houses destroyed. A master plan study and a feasibility study were conducted to prevent this type of disasters in the future.

The main components include river improvement works for two rivers and construction of steel slit dams in the upper stream, which functions to check the drifting timbers and other debris. It was the first construction of this type of slit dam in the Philippines. All the construction works completed in August 2001. Based on the proposed guidelines, maintenance works are being carried out by the Flood Mitigation Committee, which consists of the engineers of the city and DPWH as well as people living along the river.
