THE BIRTH OF THE HYDRO-REGION. The Continental Compact incentivizes a series of Hydro-regions, each leveraging a piece of new infrastructure in an existing water basin. The resulting megalopolis allows new water-rich urbanism to grow over a period of one hundred years. Conversely, it allows existing water-poor urbanism in Los Angeles, San Diego, San Francisco, Phoenix, and Denver to slowly shrink via attrition. The positive environmental and financial benefits of the revised policy will be significant, saving energy, reducing carbon emissions, slowing subsidence, lowering infrastructure costs, and regenerating California’s deltas.
