From the environmental point of view, future mobility (positive) and the change in the hydrological system (negative) are taken as trends from which the urban program needs to develop. This research starts with the conception that the Strategy of te Two Networks (S2N) internalizes a method that could help face the given challenges occurring both globally and as tested in San Francisco. The primary objective of this thesis, is to put this product of the Dutch planning tradition in another context and explore its potential in the San Francisco context. The theoretical foundation of the strategy for multifunctional Green-Blue infrastructures is driven by future mobility. The test-case of this approach is located in San Francisco. San Francisco lies in a unique natural context and possesses great capital which is of great value for the whole Bay Area. However, this capital is under pressure of future dynamics, caused by decades of human interference without acknowledging the natural conditions of the Bay. This uncertainty makes San Francisco an unsustainable city to for people to settle in the future. The aim of the project is to provide a method in which integrated engineering and urban planning and design will mitigate environmental crisis in a scenario of future technological interventions in mobility. Moreover, the aim is to revalue the S2N, in order to develop a conceptual framework that guides and structures this approach.
