Also this resulted to the Disaster Coordinating Council (BDCC). water overflowing on both ends of the said land bridge thus expanding areas susceptible to inundation. If the culverts are no longer effective, damming is the next possible scenario and breaching is not a remote one thus threatening the community of Lingayon from potential debris/mud flows in the future. Recommendation-continuous declogging of the culverts through dredging and/or appropriate engineering measures should be applied on the bridge.
