摘要

Urbanization is increasing globally, driving rapid development to meet housing needs, and creating major challenges for stormwater management as impervious surfaces expand. Low impact development (LID), decentralized systems that mimic natural processes of infiltration, evaporation and retention, is widely promoted to mitigate these impacts. However, traditional LID approaches often prioritize hydrological performance alone, neglecting broader social and ecological benefits (i.e., recreation, aesthetics, biodiversity). This study introduces an approach adapted from Kaykhosravi et al. (2019) to integrate hydrological-hydraulic performance, but here we also incorporate social well-being (SW) indicators into the planning process for a new development. We propose the LID Priority Index (LIDPI), combining a Hydrological-Hydraulic Index (HHI) and a Social Well-Being Index (SWI) using GIS-based analysis. Applied to a new residential development in its planning phase, results show that priority locations for LID shifted substantially when social benefits were included. This framework enables planners to embed social well-being benefits early in design, improving environmental performance and community livability.
