The need to protect flood-management infrastructure from floods January 25, 2021 | 7:15 pm By Dr. Andreas Klippe Eleven years ago in September 2009, Tropical Storm Ondoy (international name: Ketsana) plunged many parts of the National Capital Region (NCR) into waist- to rooftop-level floodwaters. The people of NCR, especially those in the cities of Pasig, Quezon, Manila, Caloocan, Muntinlupa, and Marikina lost their homes and livelihoods. Some, unfortunately, lost their lives. Cold, tired, hungry, and weak, some even had managed to climb the highest parts of their houses, waiting for the flood to cease. Eleven years later, with the horror of Ondoy still in the consciousness of some, another typhoon struck the capital. Typhoon Ulysses (Vamco), again, brought the people of NCR to another horrendous, heart-stopping calamity.
