DAVAO CITY – In a decisive move to mitigate the perennial flooding that affects low-lying coastal communities, the Davao City Local Government Unit (LGU), in coordination with the Department of Public Works and Highways (DPWH), officially broke ground on a PHP 450-million flood control system this morning. The project targets three of the most vulnerable barangays: Bucana, Maa, and Talomo Proper.
City Mayor Sebastian “Baste” Duterte led the ceremonial unveiling of the project plaque at the Bucana Elementary School grounds, emphasizing that the initiative is not just about infrastructure but about safeguarding the lives and livelihoods of nearly 15,000 residents who have suffered from water surges during the southwest monsoon (Habagat) and tropical cyclones over the past decade.
“Every year, we see the same images—ankle-deep mud, damaged electronics floating in the streets, and children having to be rescued from rooftops in the Bocaue area. This is our administration’s concrete answer to that recurring nightmare,” Mayor Duterte stated during his 15-minute address. He added that the project is fully funded by the national government’s “Build Better More” program but is being prioritized by the local Disaster Risk Reduction and Management Office (DRRMO).
Engineering Details and Scope
Engineer Reynaldo Tagle, the project head from DPWH-Davao, explained the technical components of the plan. The project is divided into two phases. Phase one involves the construction of a 2.7-kilometer concrete dike reinforced with sheet piles along the Davao River delta, where water frequently backflows into residential zones during high tide. Phase two includes the installation of five automated pumping stations equipped with real-time water level sensors that will alert the city’s command center the moment flooding reaches critical levels.
“We are using a ‘retention and drainage’ hybrid model. Instead of simply pushing water downstream, we are creating two temporary storage basins in Barangay Maa that can hold up to 18 million liters of stormwater. This will release pressure on the main river channel,” Tagle explained. He noted that construction is scheduled to last 18 months, with the target completion set for December 2027, just before the next major typhoon cycle.
Community Reaction and Resettlement Concerns
While officials celebrated the groundbreaking, some residents voiced mixed reactions. Lurline Sarmiento, a 58-year-old sari-sari store owner in Barangay Bucana, expressed relief but also anxiety. “We are happy they are finally doing this. But the engineers told us that to build the dike, our houses that are within the 10-meter easement zone will have to be demolished. Where will we go? We have been here for 30 years,” she told this reporter in an interview.
Addressing these concerns, City Planning Coordinator Ivan Cortez clarified that the LGU has allocated a separate PHP 50 million budget for the relocation of at least 200 informal settler families (ISFs) affected by the dike’s footprint. “We have identified a resettlement site in Barangay Los Amigos, Tugbok District. The area is already being prepped with basic utilities. We are not evicting them without a roof to move to,” Cortez assured. He added that a social mapping team will begin door-to-door surveys next week to validate affected residents.
Integration with the Coastal Road Project
The flood control project is not an isolated effort. It is strategically linked to the ongoing Davao City Coastal Road, a 18-kilometer thoroughfare that aims to decongest the city center. Engineers confirmed that the new dike will actually serve as the foundation for a multi-purpose bike lane and pedestrian walkway, turning a safety feature into a recreational amenity. This dual-purpose design mirrors similar successful projects in Bangkok and Rotterdam, adapted to local seismic and weather patterns.
Seasonal Outlook and Weather Warnings
The groundbreaking comes at a critical time. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) recently raised the La Niña alert, predicting above-normal rainfall for the Davao Region starting late June. While the flood control project will not be completed in time for the upcoming rainy season, the DPWH has assured the public that temporary measures—such as increased dredging of the river and prepositioning of rescue boats—are already in place.
Vice Mayor J. Melchor Quitain, who chairs the City Council’s committee on infrastructure, urged residents to remain vigilant. “This project is for your grandchildren. For now, we ask for your patience and cooperation. We have trained 200 new DRRMO responders this quarter. We are improving our early warning systems. We will get through this rainy season together,” Quitain said.
Economic Impact
Beyond safety, local economists predict that solving the flooding issue in the coastal barangays will unlock significant economic potential. The Davao City Chamber of Commerce and Industry (DCCCII) released a statement commending the project. “Flooding in Bucana and Maa disrupts supply chains for fish products and agriculture coming from the southern routes. A reliable flood control system will reduce logistics costs for small businesses by up to 15% during the monsoon months,” the statement read.
As the ceremony concluded, heavy equipment started clearing a section of the riverbank. For many watching from their wooden porches, it was a moment of cautious hope. Whether the concrete dikes and pumping stations will finally tame the Davao River’s fury remains to be seen. But for the first time in years, the city is betting on engineering, not just sandbags, to win that battle.
The DPWH will hold a community consultation meeting every Friday at the Barangay Bucana Hall to address ongoing concerns and construction updates. Residents are encouraged to attend.
