SUSTAINED investments in flood mitigation and climate adaptation are yielding measurable results in Quezon City, where the number of displaced families during the latest Southwest Monsoon (Habagat) fell by approximately 80 percent compared to last year.
Data from the city government shows that during the onset of the Habagat on July 23, 2025, a total of 10,576 families (35,847 individuals) sought shelter in evacuation centers.
Following heavy rainfall from August 2 to 11, 2026, that number dropped significantly to 2,146 families (8,220 individuals).
City officials attributed the sharp decline to science-based infrastructure under the QC Drainage Masterplan, enhanced disaster preparedness, and inter-agency coordination.
“Our priority has always been to protect the lives of our QCitizens. The significant reduction in the number of evacuees… are encouraging signs that our investments are making a difference,” Mayor Joy Belmonte said, adding that the city’s ultimate objective remains zero casualties.
Key infrastructure developments implemented by the Quezon City Department of Engineering (QCDE) contributed to managing stormwater.
Along flood-prone G. Araneta Avenue, three ongoing detention basin projects temporarily stored 2,990 cubic meters of floodwater during the August rains—58 percent of their total planned capacity.
Once finished, these basins will hold 5,140 cubic meters of water. Five newly installed flap gates along Araneta Creek also prevented backflow into drainage lines.
Additionally, newly completed retention ponds at the Quezon Memorial Circle and detention basins under covered courts in Barangays Sta. Monica and Tandang Sora effectively mitigated localized flooding.
Dredging and pumping operations were executed in tandem with the Department of Public Works and Highways (DPWH) to discharge runoff into the San Juan River.
The city complemented its structural measures with a whole-of-government response.
The Social Services Development Department managed evacuation centers and provided meals, while the Health Department distributed medicines and vaccines. Notably, the City Veterinary Department provided designated pet evacuation areas.
City officials emphasized that work will continue on the Drainage Masterplan and regional waterway coordination to address long-term climate risks.
