Mapping Green Infrastructure for Storm Water Management: A Spatial Analysis in Northern Virginia, USA

Younsung Kim*, Colin Chadduck and Vanessa Guerra

Green infrastructure is a range of measures that use plant or soil systems, permeable pavement, storm water
harvest, and reuse to store, filtrate, or evapotranspiration storm water and reduce flows to sewer systems or to surface
waters. Modifying regional capital assets with green infrastructure systems can provide multiple benefits, such as
slower rates of evaporation, reduced regional heat, and social benefits like communal green spaces. In this study, we
aim to create a spatial methodology to identify desirable places for green infrastructure where those benefits could be
maximized in communities. To apply the methodology, the eastern Fairfax County, along the Route One Corridor in
Virginia, was chosen as an experimental case. We find that multidimensional considerations can facilitate the creation
of green infrastructure systems in places where storm water mitigation capacity and capital flow are strengthened, and
long-term communal benefits are reaped more significantly.
