The United States, today, remains an auto-oriented suburban nation. To be sustainable, however, communities ought to emphasize walkability to mitigate the unsustainable negative externalities of driving. We use New Castle County, Delaware, to analyze the relationship between walkability and socioeconomic indicators and the presence of walkability-related plan recommendations from the past 10 years to determine the degree to which policies reflect best practices from literature. We find statistically significant demographic and socioeconomic differences between the most walkable and least walkable areas in New Castle County. We also find limited recommendations that emphasize best practices from the literature and conclude that most plans evaluated in our chapter neither prioritized the elements most conducive to walking behavior nor provided detailed policy prescriptions that would aid implementation efforts.
