In this graduation project, I have tried to focus on the aspects of socio-economic development and resilience to sea level rise in the San Francisco Bay region. The comparison is between two cases namely East Palo Alto and Foster City which has a variable difference in their socio–economic the system in terms of the communities that it hosts and the vulnerability due to risk that is generated by the type of flood risk management deployed towards flooding. The project also compares the spatial quality and synergies generated by its social systems to understand what qualities exists and what qualities should be added in order to attain a sustainable urban environment.
