In urban and suburban settings, storm water management and design is a well-developed and widely practiced profession, but the situation in exurban areas is far different. Beyond the metropolitan fringe, lower residential densities and smaller capital budgets limit storm water improvements, which heighten the need for sound storm water management by planners and private property owners. This chapter describes the impact that dissection of landscapes by infrastructure can have on storm water and stream stability in exurbia. It considers how, and why, roads and utilities and the siting of homes and exurban subdivisions impact drainage networks and contribute to flood hazards. Recommendations for dealing with storm water management in exurbia are also discussed.
