Low Impact Development (LID) strategies offer multiple benefits, including flood prevention, urban diffuse pollution control, and the creation of alternative water sources by increasing permeable surfaces. This study applies a multi-scale, multidisciplinary holistic and adaptive strategy framework for flood management in a high-density urban area in Ankara to identify suitable zones for LID implementation. The framework integrates field research, remote sensing, statistical learning, and expert input bridging engineering and urban planning perspectives, consist of (i) LID land suitability at the pixel scale and (ii) LID planning with prioritization at the neighborhood scale. Land Use and Land Cover classification was conducted on Google Earth Engine using the Random Forest algorithm and WorldView-4 satellite imagery. Six commonly used Multi-Criteria Decision-Making (MCDM) methods were employed to assess land suitability using MetaRanking. Neighborhood-scale analysis identifies priority zones for LID implementation by evaluating building density, runoff accumulation, and the intersections of impermeable surfaces with high-density areas. According to MCDM findings, bioretention cells are the most suitable LID type (29.8 %), while rain barrels account for 24.1 % of building coverage. The suitability analysis highlights the northwestern region of the study area as a priority zone for LID applications. Proposed green corridors and permeable pedestrian pathways can further enhance water retention and urban resilience. The plant species selected for LID systems are drought-tolerant, region-specific, and derived from floristic studies conducted in Ankara, considering both ecological and aesthetic contributions. This holistic approach addresses the complexities of urban hydrology, spatial planning, and socioeconomic dynamics, promoting sustainable and equitable urban landscapes.
