Treasure Island is sinking. This speculative proposal faces this difficult reality head on and uses it as a starting point for rethinking the highest and best use for the almost 100 year old, man-made island on San Francisco Bay. The design proposes a radical combination of hyper-dense urbanism combined with abundant nature, one reinforcing the other.

By shoring up the Western (seaward) side of the island with a dense urban spine, the Eastern half of the island is saved from erosion by strong bay currents and freed up to become outdoor space for recreation, native plant and animal habitat, and a site for harnessed natural processes such as water filtration and food production. The high density commercial and residential life at the heart of the Bay provides a potent economic and conservation engine for the entire area while demonstrating a more sustainable vision for the future.
