A satellite-monitoring research agenda for urban stormwater infrastructure: capabilities, gaps, and a community-benchmark proposal

Saurav Kumar 

Urban stormwater best management practices (BMPs) are a core component of urban-resilience portfolios worldwide. Per-asset performance monitoring, however, is both limited and difficult to enumerate at the global scale. We argue that publicly available satellite Earth observation has reached the capability point at which the resulting accountability gap can be closed at portfolio scale, and that the binding constraint on this transition is now community benchmark data rather than satellite data. We identify three operational capabilities available now. First, Human-in-the-loop segmentation efficiently yields survey-grade asset footprints. Second, the BMP type, historically the most difficult to discriminate, is recoverable from learned multi-physical embeddings. Third, per-asset spectral departures beyond seasonality and regional weather are detectable. All three capabilities share the same underlying gap: a lack of community benchmark data that limits operationalization. This is the single research-agenda priority capable of converting present-day satellite capability into deployable accountability for a major class of urban environmental infrastructure that today operates with little per-asset verification.
