Floods seriously threaten economies, infrastructure, and communities, making them one of the most common and destructive natural events in the world. Practical flood management strategies and risk assessment are essential to mitigate these risks. This study aimed to design and develop a Web-GIS FRiMap Platform intending to establish a spatial database for assessing the barangays in flood-prone areas in Sagay. It also provided accessible and user-friendly tools for flood risk assessment and mapping. A Rapid Application Development (RAD) model was employed in the system's development, prioritizing excellent results and a rapid design cycle. The five evaluation criteria utilized were derived from ISO 25010:2011 software quality standards which included functional suitability, performance efficiency, usability, security, maintainability, and portability. The statistical tool Jeffrey’s Amazing Statistics Program (JASP) was also employed to calculate the grand Mean. The results showed that the developed platform received high effectiveness ratings from IT specialists, achieving a grand mean score of 4.40, which was interpreted as excellent, and from end-users, achieving a grand mean score of 4.53, which was also interpreted as excellent, indicating that the newly developed system offers a notably satisfactory quality. Furthermore, FRiMap empowers decision-makers, planners, and communities to proactively address the challenges of flood hazards and promote sustainable development. The Disaster Risk Reduction Management Office (DRRMO) recommended integrating a device for monitoring water levels, triggering alarms, and sending Short Messaging Service (SMS) notifications to responders during flooding events.
