The Municipality of Taytay in Rizal, Philippines, is increasingly exposed to overlapping natural and public health hazards. With the compounding impacts of typhoon-induced flooding, rain-induced landslides, and dengue outbreaks, the need for an integrated and strategic disaster risk reduction and management (DRRM) framework is urgent. This research presents a comprehensive multi-hazard action plan anchored on the four DRRM pillars: Prevention and Mitigation, Preparedness, Response, and Rehabilitation and Recovery. Through mixed-methods research—comprising community surveys, key informant interviews, and document review—the study identifies local strengths, weaknesses, and opportunities for hazard response. The action plan targets the municipality’s most vulnerable barangays and outlines actionable programs, projects, and activities (PPAs), emphasizing capacity-building, early warning mechanisms, infrastructure maintenance, and community education. It aims to enhance coordination among stakeholders and strengthen Taytay’s resilience to concurrent disasters. The study contributes a practical model for other local government units (LGUs) facing similar multi-hazard risks.
