Northern Samar boosts coastal resilience with latest flood prevention structure

By David Vera

The Department of Public Works and Highways (DPWH) has announced the completion of a new flood prevention structure in Barangay Rawis, Laoang, Northern Samar, aimed at protecting coastal communities increasingly vulnerable to rising sea levels and stronger storms.

The flood mitigation structure includes a 117-meter reinforced concrete revetment built on a steel sheet pile foundation, along with a concrete road, sidewalk with curb and gutter, and two reinforced concrete box culverts to manage water flow. The project was funded by the General Appropriations Act of 2024, with a total budget of Php 29, 300, 446.86.

Designed to withstand strong wave action, the structure is positioned parallel to the shoreline to mitigate the effects of erosion and flooding in the area. The infrastructure is part of a broader effort to address climate-related challenges that have increasingly affected the Philippines, one of the nations most at risk from climate change.

In addition to enhancing coastal resilience, the new structure is expected to bolster the local economy and improve the quality of life for residents by providing protection from storm surges and reducing the risk of damage to homes and businesses. Community members, including long-time resident Maria, have expressed optimism about the project, viewing it as a source of security against severe weather.

This project is part of the Philippine government’s climate adaptation strategy, with DPWH prioritizing resilient infrastructure to protect communities at risk. The work in Northern Samar reflects a commitment to sustainable engineering solutions in response to environmental challenges, serving as a potential model for other vulnerable coastal regions.

The DPWH’s completion of the flood mitigation structure in Rawis represents a significant investment in the region’s future, enhancing community safety and fostering resilience amid evolving climate threats.
