For the past 3 days already, I have been stuck in my condotel due to the heavy rains and flooded streets in Metro Manila. Although technically, the private corporations have not suspended work and I can easily go to the office to report, my co-workers who come from farther parts of the Metropolis are either stranded or worst, flooded, and hence can’t come to work. So rather than coming to the office to report to an empty space, it will be better to simply stay inside as advised by government agencies.
But being stuck inside in this weather, miles away from home, although comfortably dry and well-provisioned, is anything but fun. It does get boring after a day and a half of virtually doing nothing, just sitting in front of the computer. Soon, movie marathons become passe and staring at Facebook status and Twitter feeds become mind numbing. Reading online articles lose their appeal and I would want nothing more than to simply go out there and be part of the action.
Of course, I can be a volunteer but on second thought, I’d rather stay inside and keep dry. After all, despite everything being familiar, I am still on foreign grounds.
Metro Manila, in the past, didn’t get flooded this bad. I recall that it was my hometown in Bicol which was regularly afflicted with stormy weathers and the constant recipient of donated relief goods. But now, it seems the tides have changed and areas which didn’t use to be affected are now severely affected. So the question, begging to be answered, is why?
I found this information post in Facebook which summarizes the answer to that question – WHY?
10 Reasons Why It Floods in Manila
By: Paulo Alcazaren
It’s the rainy season once again and we face the yearly problem of flooding in Metro Manila. I keep getting calls from broadcast media asking for interviews about the problem, its historical origins and urban redevelopment solutions. Giving these interviews I feel like a broken record enumerating the reasons for floods in the metropolis, so I figure it would be good just to list them once and for all. This list may not contain all the reasons but these, in my opinion, are the major ones:
1. It floods because it rains. The rains and the typhoons that bring them have increased in magnitude. Yes, it’s Climate Change. To deny this is futile. It’s here now and makes all historical flood levels well, history. The paths of typhoons have also become unpredictable (not that we have enough weather men to predict them—many of our good ones have left for better-paying jobs overseas). Typhoons now cross parts of the archipelago that did not use to have them regularly and so people are caught unprepared. Despite these changes in patterns, Metro Manila still gets dumped with rain, especially since its total area, and population in this area, is equivalent or larger than most provinces and many regions in the country.
2. It floods because of population and urbanization. Metro Manila has a population of 12 million and counting. Urbanization, specifically urban sprawl is a manifestation of all these millions living together and needing houses, buildings, roads, parking lots and infrastructure. All these cover ground that used to be open and which used to be able to absorb much of the storm water that fell on the metropolis. In our lifetimes we’ve seen fringes of the metropolis gobbled up and transformed from cogon and rice fields to thousands of subdivisions, hundreds of shops and malls, hectares of paved-over parking lots, dozens of business districts. All this hard covering serves to channel all the storm water much faster into an already inadequate drainage system designed decades ago when the reality was much more open land and much less rain. The open ground before served to mitigate the volume of rain that flowed into these drains, esteros and our rivers. We also had more plant cover and trees in the metropolis to help sop up all this water. Our previously open parks are now covered too with all manner of government buildings or basketball courts and parking lots.
3. It floods because the rain comes down from denuded uplands. Metro Manila floods come from elevated surrounding regions, all the way up to the Sierra Madres. There, we have lost almost all of our original forest cover from illegal logging. All this forest cover lost makes millions of hectares of upland a bald watershed that flows freely into the metropolis. This situation is repeated around almost all major urban areas in the country. The source is upstream and this is where solutions should start, although it is among the longest-term solutions. We need to recover our forest cover to reduce the amount of rain that floods our low-level metropolis.
4. Metro Manila is not only low but it is sinking. Ground water extraction due to deep wells is causing major areas of the metropolis to sink. The north section of CAMANAVA and the southern cities from Pasay onwards have sunk from a foot to over a meter and this has made those areas more vulnerable to floods and storm surges. Scientists have pointed to the fact that this flattening has increased the reach of storm surges from the seaside to as much as twenty kilometers inland. So we get it from both ends in a perfect storm—from the mountains and from the sea. The ground is also sinking due to the weight of all that concrete, buildings and infrastructure mentioned in reason no. 2 above.
5. It floods because we have less drainage than before. Reports have it that we have lost almost half of our metropolitan esteros and canals. We used to have over forty kilometers of them and now we only have about twenty. Many have been lost to development, disappearing without a trace (now it regularly floods where they used to be of course).
6. It floods because many of those esteros, canals and waterways of our metropolis we have left are chock-full of informal settlers. Because there are no alternatives for low-income mass housing, desperate people settle in desperate areas. These settlements have little by way of solid waste management and sewers. All these go to the waterways, filling many of them so solid that dogs can cross over them. And we wonder why it floods. Many of these drainage ways and easements were identified in the several master plans made for Manila and Quezon City. Planners over half a century ago had allocated as much as 50 meters of space on either side of these but greed set in and these easements disappeared and what little was left are now our favelas teeming with millions.
7. It floods because the main flood control system started in the 70s was never completed. The Manggahan floodway was only one half of the picture. It was meant to channel floodwater into Laguna de Bai. The lake was meant only as a holding area and the excess water was to have been flushed from there to Manila Bay via the Paranaque spillway. That spillway was never built. To build it now would cause trillions and urban sprawl has seen its path covered with more millions of people and thousands of structures.
8. It floods because what little left of our drains and flood control infrastructure is ill-maintained. Reaching many of them is a problem because of informal settlements. Overlapping jurisdictions of local and national agencies conspire to dissipate responsibility and funding for this vital task of ensuring our drains are unclogged and free. It’s just like homeowners not cleaning their gutters of debris before a rainy season. When the typhoons come the gutters overflow.
9. It floods because urban development is un-planned and unfettered. Mega-developments that see clusters of 30-40 story towers on retail podiums surrounded by hectares of parking cause havoc in districts planned with drainage infrastructure meant for low-density development. Because there is a lack of planning context (actually a lack of any planning at all) all drainage, road and traffic infrastructure is useless to carry the additional load—that’s why most flooded areas are also traffic-clogged.
10. The final reason it floods in this short list (and there are many other reasons) is politics. Metro Manila is made up of 16 cities and one town (Pateros). Floods do not respect political boundaries and will flow from one city to the next yet we continue to address flooding (as well as all other urban problems) within the confines of individual LGUs. It does not make sense. Politics also conspires to keep informal settlers where they are because they represent votes. The overlapping jurisdictions is also exacerbated by another layer—that of national government and yet a third layer on top of these, that of the MMDA. The ultimate fourth layer of discord is the fact that the source of floods is beyond the political jurisdiction of Metro Manila and in the hands of the provinces around it. Any sustainable solution to flooding must be at this regional context and the assumption that, within the metropolis, governance is rationalized to address this one big problem as one effort, not the uncoordinated effort of seventeen government units, the MMDA and national agencies. Politics has divided and conquered us …and it is also drowning us in yearly and constant floods.

Given the above reasons, what is the best way to solve this flooding problem in Metro Manila? I say, we begin providing solutions for the 10th reason above. LGUs, not just in Metro Manila but also in the adjoining regions should come together as one and share the responsibility of addressing the solutions for the other reasons provided. If you look at it, it is never too late to start solving today’s problems for a brighter tomorrow. All it takes is the discipline and the drive to actually do something about all this.
Have a safe and dry week everyone!
