The population density in Jersey City and Hoboken is rapidly increasing. At the same time, climate change and poor drainage systems also plague these two cities. These problems create multiple interrelated issues like a lack of open space and a need for flood mitigation. On the other hand, there are many vacant lots in the city fabric, both private and public. This design proposal focuses on borrowing private lots over a period of time to create temporary pop up spaces and redesigning permanent vacant spaces to resolve flash flood issues on publicly owned lots.
