Objective:
After the flood events brought about by
typhoons Ondoy and Pepeng in September and October 2009, respectively,
that caused severe damage in Metro Manila and surrounding areas, the
World Bank has provided a technical grant in the amount of $1.5 million
under the Global Facility for Disaster Reduction and Recovery Trust Fund
of the Australian Agency for International Development (AusAID).
A flood risk assessment study for the
entire Metro Manila and surrounding basin area was undertaken from
February 2011 to February 2012, to prepare a comprehensive flood risk
management plan for the same and to determine a set of priority
structural measures, which will still undergo individual feasibility
studies and detailed design prior to implementation, including
nonstructural measures that will provide sustainable flood management up
to a designated safety level and serve as the roadmap/vision of the
government until 2035 (23 years from now).
Guiding principles for master plan development:
1. Adopt the principles of integrated water resources management and river basin approach
2. Develop a safe society with resiliency to floods through:
- Structural measures for the river basins and waterways
- Structural measures for the Laguna lakeshore, and
- Improvement of the urban drainage system
5. Strengthen community-based flood risk management—land use and solid waste
6. Utilization of runoff waters as water resources, etc.
7. Reforestation and watershed management
Three major flooding occurrences:
1. Huge volume of water coming from Sierra Madre
2. Drainage capacity constraints in core area of Metro Manila
3. Low-lying communities around Manila Bay and Laguna Lake
