Facing a lot of challenges brought by climate change, this thesis aims to explore long-term landscape-based solutions for the vulnerable low-lying area in Miami-Dade County to increase the adaptation towards Climate Change through the integration of flood impact mitigation and environment enhancement on spatial-social-ecological aspects. Public spaces are taken as the potentials and transformed into landscape infrastructures, building up the landscape infrastructure system which could facilitate functional, ecological and social relationships between human and natural processes. This system integrates water layer, vegetation layer, and activity layer which could bring multiple values in order to achieve the goal of flood impact mitigation and environment enhancement at the same time.
