This article develops automated, open-data-driven routines for identifying and dimensioning decentralised Nature-Based Solutions within existing urban catchments, introducing a block-based metric for stormwater mitigation potential and demonstrating, through a case study in Lyon (France), that strategic spatial allocation of interventions can yield significant project cost savings while achieving combined sewer overflow reduction targets.
