Sustainable Community Transformation and Planning Based on Community Layout and Low Impact Development Concept

Abstract

The Sustainable Cities and Communities emphasized in the United Nations Sustainable Development Goals are cities and residential communities that prioritize inclusivity, safety, and resilience against disaster risks. China's urbanization process has embarked on a trajectory of rapid development, characterized by substantial advancements in urban construction and continuous enhancements to the urban landscape and environment. Confronted with an immense urban population scale, the sustainable transformation of traditional communities has emerged as the primary focus for establishing resilient communities. This paper compares the disparities between communities established by the traditional community model and sustainable community concept, scrutinizes the limitations of traditional community models, and proposes strategies for the sustainable transformation of traditional communities through adopting low impact development concepts in rainwater management. For the "block" layout, this paper proposes enhancing the connectivity of green spaces and promoting diversity. For the "central" layout, it is recommended to optimize access roads, including pedestrian and vehicle routes, by integrating green spaces. In the case of an "intensive" layout, emphasis should be placed on improving resource utilization efficiency through multi-functional approaches. For the planning of new sustainable communities, this paper puts forward suggestions from the micro and macro planning levels.
