A self-sustaining biofiltration system prevents flooding in San Francisco’s sport stadium and protects the nearby San Francisco Bay and freshwater resources from stormwater pollutants. Mark Lehnerz of Oldcastle Precast explains how. A large construction project such as a major-league sports stadium can include significant expanses of runoff-generating hardscapes.
