The very existence of New Orleans has historically been defined by its relationship to water. The city was founded at a key strategic location on the Mississippi, where it controlled military and trade access to the river. Nevertheless, today the city has a deeply troubled relationship with water. Within the city, continuing subsidence increases the city’s vulnerability to flooding. Outside the city limits, the coastal land loss threatens the very existence of the city in the next 100 years. As the coast moves inland, it creates confusion about what is coast and what is lake and where the city could exist. While not yet clearly perceived, the city is now truly coastal and connected directly to the Gulf of Mexico through its eastern shore, on the formerly enclosed Lake Borgne, now open to the Gulf. The entire map of the coast has changed and our understanding of the relationship between land and sea needs to catch up to reality (Figure 14.1).
