Expanding impermeable surfaces has increased localized flooding and stormwater management challenges in cities, suburban areas, and small towns. Green stormwater infrastructure can reduce stormwater runoff through infiltration, storage, and evapotranspiration; however, these installations have high variability in hydrologic performance. By combining field-collected native soils data, modeling, and surface design, this work rethinks green stormwater infrastructure in place through community research co-creation with quantitative evaluation of green stormwater infrastructure performance in context. Probabilistic models predict green stormwater infrastructure failure based on variability in space and time. Results indicate that green stormwater infrastructure can function reliably in combination with grey infrastructure under a wide range of conditions, with important environmental justice considerations in sustainable stormwater management.
