CABRAL, PhD. Undersecretary for Planning and Public Private Partnership Service, Department of Public Works and Highways and 2017 National President – Philippine Institute of Civil Engineers (PICE) Building a Disaster Resilient Philippines Manila Polo Club, Makati City 25-26 April 2017 A NATURAL DISASTER CAN PARALYZE TRANSPORTATION SYSTEMS LOSS OF FUNCTION OF A TRANSPORTATION SYSTEM CAN PARALYZE LOCAL, REGIONAL, AND INTERNATIONAL EMERGENCY RESPONSE FEATURES THAT AFFECT RESILIENCY ▪Different modes of trans-portation are interconnected ▪They interact with each other and other elements of a community’s built environ-ment; hence, the name, Lifeline systems”. ❑ HIGHWAY SYSTEMS Flooding from tropical storms, and typhoons, Landslides (rock falls, spreads, slides, flows) Earthquakes Livable, Sustainable and Resilient Communities (Disaster Risk Reduction and Climate Change Adaptation Program) What is being been done so far BY DPWH? 5 2017-2022 Philippine Development Plan Key Principles of Spatial Development Integration of leading and lagging areas and urban-rural linkages through transportation networks Improvement of access to social services Identification of locations of major infrastructure to maximize their benefits Improvement of local, national, and international connectivity Promotion of sustainable development and Source: pdp.neda.gov.ph resiliency 2017-2022 Philippine Development Plan Strategic Framework (Targets) Growth in gross domestic product (GDP) is expected to strengthen at 7 to 8 percent. Growth will be more inclusive as manifested by a lower poverty from 21.6 percent in 2015 to 14.0 percent in 2022. Unemployment rate will decline from the current 5.5 percent to 3-5 percent in 2022. Greater trust in government and in society. Individuals and communities will be Source: pdp.neda.gov.ph more resilient.

DPWH Commitment (Disaster Risk Reduction and Climate Change Adaptation) Slope Protection ▪ Construction of Slope Protection will ensure that accessibility and mobility of the National Road Network is unhampered during the occurrence of natural disasters ▪ All the slope protection projects along the Primary Road Network within the Provinces with Medium to Very High Level of Risk to Typhoons and Geophysical Disasters identified by Manila Observatory and DENR will be committed in the PGS Scorecard Livable, Sustainable and Resilient Communities (Disaster Risk Reduction and Climate Change Adaptation Program) A. Structural Measures: 1. Construct/rehabilitate flood Mitigation structures along major basins and principal rivers. 2. Construct water impounding projects to optimize water resources. 3. Upgrade/improve drainage capacity. 4. Construct Water Supply & Rain Water Collection System. 5. Rehabilitate, retrofit and strengthen existing bridges. 6. Provide safe and alternative access to highly vulnerable areas. 7. Improve national roads vulnerable to flooding, landslide and slope failure. 8. Build evacuation centers incorporating requirements prescribed by NDRRMC B. Non-Structural Measures: 1. Complete and update the flood control and drainage master plans and feasibility studies of Major River Basins and Principal Rivers. 2. Clear waterway easements in coordination with LGUs and MMDA. 3. Pursue accreditation of flood control engineers through capacity building and transfer of technology. 4. Upgrade quality standards based on Design Guidelines, Criteria & Standards (DGCS) 2015 which incorporates resilient design to address climate change impacts to all infrastructures. 5. Deploy equipment and manpower within 24 hours from the first advisory of NDRRMC, PAG-ASA and PHIVOLCS. 16 Livable, Sustainable and Resilient Communities (Disaster Risk Reduction and Climate Change Adaptation Program) A. Structural Measures 17 DPWH conducts assessment: Necessary for old (important) structures – long years of existence – degradation of strength/aging of materials, wear and tear, exposure to elements Need to be maintained – usage, durability, serviceability, avoid deterioration DPWH conducts assessment: Need rehabilitation/repair – construction defects, design failure, material aging - cost-effectiveness Upgrade to new standards – continuous code development based on current technology, code compliance Retrofitting/Strengthening- depends on the results of the assessment Structures for Inspection Seismic Vulnerability Assessment First Level Inspection -- Rapid Visual Screening Procedure (RVS) FEMA 154 (PICE/ASEP/OCD DQRP / Preparation of Reports DPWH-TFBBI) -- BOD Earthquake Hazards Form Detailed Evaluation Required?
