Popis: The Philippines is prone typhoons due to its geographical location. The municipalities of Los Baños and Bay in the province of Laguna are highly flood-prone due to their proximity to Laguna de Bay or Laguna Lake. Large areas of Bay fall within the watersheds of Mt. Makiling Forest Reserve (MMFR) which are tributaries to the lake. The back flow of water into the trubutaries during heavy rainfall can cause flooding and result to socio-economic and physical impacts. The study aims to: determine the association of typhoon awareness, mitigation practices, and resilience practices with the socio-economic and socio-demographic profile of Barangay (village) Santo Domingo residents; generate a Flood Susceptibility Map, map the designated evacuation sites using Geographic Information System (GIS); and provide recommendations to promote awareness and reduce the impacts of typhoon. Ninety-six households were selected randomly based on the sampling design with 95% confidentiality. Key Informant Interviews (KIIs) and Socio-economic surveys (SES) were also conducted. STATA ver. 12 and Fisher’s exact test were used to evaluate the significance of the socio-economic and socio-demographic components in relationship to awareness, mitigation, and resilience. Barangay Santo Domingo has high level of awareness (0.9647), high level of mitigation practices (0.8303) and high level of resilience (0.8842). The monthly income of respondents has a strong correlation with mitigation practices while house ownership signifies moderate association to resilience practices. Chi-square test of independence showed that there is no significant difference among the puroks (zones within the barangay). Based on the generated Flood Susceptibility Map, majority of the land area (197.23 hectares) of Barangay Santo Domingo belongs to the high susceptibility category which led to the identification of six evacuation sites. Awareness is necessary for disaster preparedness. Effective planning and management are essential to increase awareness and reduce the detrimental effects of flooding.
