The design is structured to be achieved over three stages, between today and 2090, accommodating forecasted sea-level rise from three to twelve feet. This plan integrates regional ecologies including a flood-plain forest, wind gap meadows, and tidal marshes, bringing an overdue ecological point of view. Monuments are adapted, protected, or relocated. This will make the Tidal Basin: A Place for People that will be better integrated into the experience of future generations through improved scale, connectivity, and flexibility of space; A Cultural Landscape in which ecology will merge with history and culture for a more complex and meaningful landscape; and An Engineered Landscape where infrastructure and actively managed ecology will mediate the natural and the man-made, securing the National Mall from rising tides.
