East Hampton Town needs a summer plan. Relatively recently, officials presented a set of hamlet-specific vision documents intended to guide redevelopment and new projects in the commercial centers with an eye toward a mix of business and residential needs and an emphasis on affordable living for workers. These studies were quite nice and contained some exciting ideas. What the hamlet plan authors did not do was look at the reality of East Hampton’s resort, day-trip, and short-term rental economy in a coherent way.
