Mayor Celso Lobregat yesterday afternoon urged officials of barangays identified as prone to flashfloods and landslides to develop an early warning system in a bid to reduce the risk in case of disaster and other environmental hazards.

Lobregat said the early warning system is very important in every barangay to alert the people of the impending disaster and pave way for the evacuation to safer grounds, thereby reducing the risk of any disaster.

“They should come up with a master plan on the preparedness and mitigation such as determining the evacuation sites, escape routes, mode of transportation, and early warning system per type of geohazard that should be incorporated in the general disaster plan,” the chief executive said, citing the recommendation of the Mines and GeoSciences Bureau.

This, as he warned that flooding is imminent because the city proper is situated on a low-lying deltaic and flood-plain environment where the elevation is typically below 5 meters above the mean sea level.

A geohazard investigation of the Geosciences Division of the Mines and GeoScience Bureau showed that of the city’s 98 barangays, 77 are susceptible to flood during incessant rains.

These are (High Risk) Ayala, Baliwasan, Calarian, Campo Islam, Labuan, Limpapa, Maain, Mariki, Paonanca, Patalon, Recodo, Rio Hondo, San Jose Cawa-Cawa, Sinubong, Sinunuc, Sta. Barbara, Sto. Nino, Talisayan, Zones 1-4, Arena Blanco, Bolong, Busay, Cacao, Culianan, Dita, Divisoria, Guisao, Guiwan, Lamisahan, Landang Gua, Landang Laum, Licomo, Limaong, Lunzuran, Manalipa, Manguu, Muti, Pangapuyan, Panubigan, Pasilmanta, Putik, Quiniput, Salaan, Sangali, Sta. Catalina, Taguiti, Talon-Talon, Taluksangay, Tictabon, Tumitus, Tugbungan, Tumalutab, Victoria, Vitali, (Moderate to High) Camino Nuevo, Canelar, Cawit, La Paz, San Jose Gusu, San Rque, Tulungaung, Tumaga, Boalan, Bunguiao, Cabaluay, Curuan, Kasanyangan, Mampang, Manicahan, Sibulao, Talabaan, Tetuan, Tictapul and Zambowood.

The same geohazard investigation report also identified the 44 landslide-prone barangays (High Risk) as Tumaga, Divisoria, Lumayang, Lumbangan, Mercedes, Muti, Putik, Salaan, Sibulao, Tagasilay, Taguiti, Tigbalabag, (Moderate to High) Baluno, Cabatangan, Capisan, Dulian (Upper Pasonanca), Labuan, Limpapa, Maain, Malagutay, Pamucutan, Pasonanca, Patalon, San Roque, Sinubong, Sinunuc, Tulungatung, Bunguiao, Cacao, Calabasa, Curuan, Dulian (Upper Bunguiao), Guisao, Lamisahan, Lanzones, Lapakan, Lauan, Lubigan, Lunzuran, Quiniput, Sangali, Tictapul, Tolosa and Vitali.

The study concluded that urban development reduces the capacity of natural underlying materials to absorb rain water. Clogged sewer/canals also add to the problem of flooding. Waste materials are dumped along rivers and creeks which also amplified the problem.

Coastal hazard, according to the study, is another problem since there are residential dwellings within tidal flats and high tide levels. Cultural issue holds back permanent solution to this circumstance.

It was recommended that the effects of storm surges and possibly tsunamis could be mitigated through establishment of buffer zones of about 50 meters above and away the highest tide level for the community along the shoreline. To avoid potential direct threat to the lives of the community, it is highly prohibited for the community to reside within mangrove areas and tidal flats. — Vic Larato
