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

3

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

Project Description: • Cagayan River - Revetment structures for the most serious eroded areas of land by river flow were selected at suitable sections, namely Alibago, Enrile and Cataggaman Sites.

• Tagoloan River - Construction of river dike and partial excavation of river channel together with drainage channel improvement.

• Imus River - Construction of two off-site retarding basins along Imus River.

Project Cost: • P 5,411 Million (USD124.40 Million)

NB Approval: • November 8, 2011

Status: • As of 25 March 2014, the consultancy works for the DED is 27.70% complete.

Asset Management of Flood Control and Drainage Structures

• Establishment of improved/upgraded flood control database system using

GIS and GPS technology

• Development of mechanism for efficient Asset Management System (AMS)

• Evaluation of the existing and proper study of future communication system

for AMS

• Formulation of Operation and Maintenance (O & M) Manual

• Training of flood control engineers on database management

• Evaluation of the achievement and progress of FRIMP including

sustainability activities
