DPWH Flood Risk Management and Resiliency Program

Outcome:

Protect lives and properties against major floods and other calamities

Strategy No. 1

River Basin Approach for Effective Flood Control Program

Actions Taken:

• Adopt “river basin approach” in preparing master plan and feasibility study of flood management and water resource management • Ongoing implementation of the Flood Management Master Plan for Metro Manila and Surrounding Areas • Complete the master plan and feasibility study of the 18 major rivers by 2016 • Prepared/submitted to OP proposed Water Sector Restructuring Plan adopting an Integrated Water Resources Management approach in a convergence program with DA, DAR, NIA, and DENR • Upgraded engineering design standards for flood control, drainage and slope protection works 2

DPWH Flood Risk Management and Resiliency Program: Outcome:

Protect lives and property against major floods and other calamities

Strategy No.2

Design and construct disaster resilient public infrastructure facilities.

Actions Taken: • Implement Structural Resiliency Program in new construction and in the reconstruction of calamity damaged infrastructures upgraded roads and bridges, school buildings, hospitals, public housing, and other infrastructure facilities • Recover road right of way of critical national roads and bridges and upgrade design to ensure flood-free at all times • Identify public facilities as safe Shelter Centers in disaster prone municipalities for resilient design and redundancy to also be used as emergency command center and evacuation facility • Use geo-hazard maps and NOAH data for infrastructure planning and disaster risk reduction measures • Strict enforcement of water easement laws and removal of informal settlers and structures on waterways and no build zones 3
