New Manila International Airport. North-South Commuter Railway. Clark Freeport Zone. Infrastructure-driven appreciation. Land values rising 10 to 13 percent annually. The next CALABARZON. Buy now before prices double.
All of that is true. And none of it is the complete picture.
The complete picture includes 116 barangays in Bulacan submerged in one to six feet of floodwater as recently as August 2026. A water crisis so severe that San Jose del Monte declared a state of calamity in February 2026, affecting 250,000 people with dry taps. Residents in Calumpit who say they flood even during the dry season when there is high tide. And a groundwater depletion problem in Pampanga that engineers warned about years ago and that continues to worsen.
This guide gives you both sides of the story, the genuine infrastructure upside and the genuine livability risks, so you can make a property decision based on the complete truth rather than one half of it. This post connects to our How to Check if Your Property is Flood Prone Philippines and our Real Estate Investment Philippines: The Complete Guide.
Before the risks, the upside deserves honest presentation. The infrastructure investment flowing into Central Luzon is real, significant, and historically the most reliable driver of Philippine property appreciation.
The New Manila International Airport is being developed on a 2,500-hectare reclaimed site in Bulakan, Bulacan. Phase 1 construction began in January 2026 with two runways, a modern terminal, and facilities designed to serve up to 35 million passengers annually. Completion is expected by end of 2028.
The total project cost is PHP 735 billion, making it one of the largest private infrastructure investments in Philippine history.
SMC chair Ramon Ang said the first runway could be completed ahead of schedule, though the passenger terminal and logistics center may take longer.
The airport will be connected to NLEX via a dedicated six-lane highway, with proposals to extend the MRT-7 line to the NMIA site still under review.
Projected price growth for neighborhoods in the Bulacan airport corridor ranges from 8 to 12 percent annually. Property prices in Central Luzon rose approximately 6 to 9 percent over the past 12 months, with single-detached houses in Bulacan leading at nearly 13 percent annual growth.
Clark and Pampanga continue to benefit from the operational Clark International Airport and the upcoming North-South Commuter Railway Phase 1 completion expected in 2027. The area is a magnet for logistics companies, industrial parks, and executive housing. Pampanga is emerging as a key logistics hub due to its proximity to major transportation infrastructure.
Pampanga condos average around PHP 151,000 per square meter while Bulacan condos sit at PHP 126,000, making both significantly more affordable than Metro Manila’s PHP 140,000 to PHP 210,000 range. For investors priced out of BGC and Makati, this entry point combined with infrastructure-driven appreciation is a compelling combination.
House-and-lot projects outside Metro Manila have shown consistent demand. Cavite, Bulacan, Pampanga, and nearby provinces attract buyers including many overseas Filipinos seeking homes for their families. Remittances are at an all-time high and there is still a big housing backlog in the Philippines.
As recently as August 2026, 116 barangays in Bulacan remained submerged in one to six feet of floodwater with 8,728 people in evacuation centers. This is not a typhoon anomaly. It is a recurring annual reality.
Bulacan acts like the natural catch basin.
Several major rivers all flow into it:
before all of it empties into Manila Bay.
The land is flat and low, close to sea level, so once water arrives it has nowhere to go.
Rain, river water from upstream, and rising tides from the bay can all hit at the same time, with no natural slope to drain any of it away. This isn’t a risk that can be engineered away. It’s just how the land works, and it makes flooding a regular part of life there, not a rare disaster.
What makes it worse is that, the recent issue of flood control meant to manage this is often broken or unfinished. Heavy rain and river overflow put the water into the barangays in the first place. Normally it would drain back out through floodgates and channels into the river and out to Manila Bay. But in places like Barangay Iba, an unfinished floodgate actually blocked that natural drainage path, trapping the floodwater in the community instead of letting it flow out. So the water isn’t just arriving faster than before. It’s also staying far longer than it should, because the system meant to send it back out isn’t working.
That reality showed up clearly in August 2026: 116 barangays stayed underwater, one to six feet deep, and 8,728 people were still in evacuation centers. The worst hit spot was Barangay Meysulao in Calumpit, with water up to six feet. Calumpit sits right where the Angat and Pampanga rivers meet the tide coming in from the bay, so it makes sense it flooded worst. The other hardest hit towns follow the same pattern: Calumpit (28 barangays), Malolos (41), Hagonoy (25), Paombong (14), and Bocaue and Guiguinto (7 each), all of them close to Manila Bay, at the low end of the river system.
Here’s what matters most for anyone buying property. Residents of Barangay Frances in Calumpit say flooding isn’t just a typhoon thing. It happens even in dry season, whenever high tide comes in at the wrong time.
That’s the key point: it’s the land’s shape causing the flooding, not just bad weather.
Looking at flooding records over several years, the same towns keep showing up: Calumpit, Hagonoy, Paombong, Bulakan (where NMIA airport is), Bocaue, the low parts of Malolos, Obando, and Balagtas. These aren’t random, out of the way places. They’re the same towns used in ads for developments near NMIA.
Here is the specific concern that no NMIA-adjacent property marketing raises: the airport itself is being built on reclaimed land along Manila Bay in Bulakan municipality, one of the most flood-affected municipalities in the province.
Reclaimed land along Manila Bay is inherently vulnerable to storm surge and high tide flooding. SMC’s construction has already faced delays due to difficulties acquiring sand for land development.
The airport’s engineering includes flood mitigation for the site itself, but the roads, communities, and residential developments being marketed as NMIA-adjacent are not all on the same engineered platform as the airport proper.
Before buying any property marketed as being near the NMIA, verify its specific elevation, its flood susceptibility rating on HazardHunterPH, and whether the roads between the property and the airport remain passable during typhoon season. The appreciation thesis requires you to be able to reach the airport. If the roads flood every wet season, the connectivity benefit is seasonal rather than year-round.
Not all of Bulacan floods with equal severity. The municipalities with consistently lower flood exposure are those at higher elevation, away from Manila Bay and the major river systems:
San Jose del Monte (SJDM): Elevated position with significantly lower flood risk than the coastal municipalities. Connected to SJDM City by MRT-7 (under construction). Lower flood risk but, as discussed below, currently the epicenter of Bulacan’s water crisis.
Norzagaray: Higher elevation, adjacent to the La Mesa watershed area. Lower flood risk. Further from the NMIA but near established Angat River water resources.
Parts of Santa Maria and San Ildefonso: Elevated terrain with lower flood susceptibility. Due diligence required on specific barangay level.
The pattern is clear: the Bulacan municipalities closest to Manila Bay and the major river systems carry the highest flood risk and are also the most marketed NMIA-adjacent locations. The municipalities with lower flood risk are further from the airport site and benefit less directly from NMIA-driven appreciation.
San Jose del Monte declared a state of calamity in February 2026. Around 250,000 people, roughly a third of the city’s population, had dry taps. This situation persisted through July 2026.
San Jose del Monte’s PrimeWater Disaster
San Jose del Monte in Bulacan has been under a state of calamity since February 25, 2026, as more than 47,611 households across most of the city’s 62 villages faced dry taps due to poor water service delivery by PrimeWater. The calamity declaration allowed the city to fast-track relief and coordinate with LWUA, MWSS, and NWRB for long-term solutions.
The change in ownership of PrimeWater in late 2025 was widely expected to signal a fresh start. As of July 2026, thousands of families in San Jose del Monte continued to endure a debilitating water crisis with only a handful of media organizations devoting sustained attention to it.
Metro Pacific Water took over the Bulacan supply system in June 2026 with President Andrew Pangilinan acknowledging the urgency of the situation. Comprehensive rehabilitation of the distribution grid will require sustained capital deployment over an extended period.
For property investors, the water crisis in SJDM is a material livability issue. A house with dry taps is not a home that retains its value or its tenants. The Metro Pacific Water takeover is the most positive development available, but rehabilitation of a broken distribution system is measured in years, not months. Buyers targeting SJDM properties should ask specifically about water supply reliability in the specific village before purchasing, and should factor in the cost of deep well installation or water delivery as a practical interim measure.
If the risk outweighs the reward, I’d rather choose a different location, especially for long-term investment or a home I plan to live in for years.
Bulacan’s geography isn’t something that improves on its own, and flood control projects meant to manage it have a documented track record of being unfinished, underbuilt, or outright fraudulent.
Buying here for the long run means betting that this changes. Right now, that’s not a bet the evidence supports.
