Streetscape Environmentalism: Floods, Social Justice, and Political Power in San Antonio, 1921–1974

San Antonio's Zarzamora Creek, often dry and overlooked, becomes a significant force during heavy rainfall due to the confluence of meteorological patterns and geological structures. The study reveals how San Antonio's location near the 100th meridian, which separates humid East from arid West, exposes it to extreme weather events like El Niño and La Niña cycles. These conditions, combined with the Hill Country's elevated catchment basin, funnel rainwater into channels that can cause devastating flash floods. The research highlights the interplay between weather patterns, geology, and riparian systems, contributing to San Antonio's designation as 'Flash-Flood Alley' by the National Weather Service.
