BOTTOM UP STREAM RESTORATION IN AUSTIN, TX: A CATCHMENT SCALE PARADIGM SHIFT
Urban development without the benefit of stormwater controls degrades stream structure and function. Regulations that apply controls to development are in place in most cities, but there is often a large and costly legacy of dysfunctional stream systems with water quality, erosion and flooding problems and no room or economic feasibility for traditional restoration. In Austin, Texas, building on an international movement, a watershed-scale proof of concept project is taking form that will test the hypothesis that dense, distributed stormwater control measures (SCMs), on both public and private property, can significantly buffer the negative effects of legacy urban development on stream hydrology. A small, 2.8 sq km urban catchment, with 47% impervious cover was selected to examine this hypothesis. With basic stream function as the ultimate endpoint, modeling results have validated changes in key hydrology measures and an economic analysis strongly favors a private property service delivery model. In addition to distributed SCMs, this experiment includes extensive riparian restoration and an intensive focus on outreach and education that looks closely at how we think about water and cities.
