DPWH Southern Leyte braces for La Niña

MAASIN CITY, Southern Leyte, June 23 (PNA) -– The Department of Public Works and Highways Southern Leyte District Engineering Office (DPWH-SLDEO) is stepping up preparations for the rainy season, especially that many areas in the province have been tagged as vulnerable to rockslides, landslides, and flooding.

On top of regular flood control projects, the DPWH-SLDEO has been cleaning up drainage system and desilt rivers and other waterways to prevent flood water surge.

“This is our regular activity, but we have intensified this in the past few weeks in anticipation of La Niña that will likely hit many parts of our country in the second half of this year,” said District Engineer Ma. Margarita Junia.

For 2016, the DPWH has set aside PHP50 million for slope protection in landslide-prone road sections, PHP20 million for drainage rehabilitation, and PHP27 million construction of flood control system in Maasin City.

The DPWH field office has also identified specific areas from Sogod town to San Ricardo town where they will preposition heavy equipment for road clearing in the event of rainfall-induced landslides and rockslides.

These road sections are vital link from Luzon to Mindanao as part of the nautical highway’s eastern seaboard route.

With the onset of rainy season, the SLDEO reiterated its PHP109 million budget proposal to pilot a project that would completely prevent rock falls and soil erosion, utilizing Swiss technology.

The province would be the first in Eastern Visayas to pilot road slope stabilization control system developed by Swiss firm, Geobrugg.

Junia said they are proposing to pilot a section in Barangay Kahupian in Sogod town for the stabilization control project in the most critical section, which has an ascending roadway and multiple blind curves.

The technology, according to Junia, has been used as permanent solution to geohazards in other parts of the country under the Technical Cooperation Projects of the Japan International Cooperation Agency.

The Mines and Geosciences Bureau (MGB) has recently ranked Southern Leyte province as the seventh most vulnerable to heavy landslides in the Philippines. Based on MGB’s geohazard mapping and assessment, the province recorded a 78 percent landslide probability. (PNA)
