Urban Forest generally refers to all types of vegetation that grow naturally or manually, within or surround by high-density human residential areas. This definition includes grasses, shrubs, and other vegetation, it is particularly that the most important component is urban trees, whether in individual or group forms, and in private as well as public space. (Blum, 2017) So, what if we plan ‘urban forest’ on the street? The street is a system: a transportation system, an ecosystem, and a system of social and economic interactions. The idea of a streetscape ecosystem is to mimic nature, building reciprocal relationships within an interconnected system to sustainably enhance the local environment, its resources, the community, and the local economy. Moreover, the street is a constructed waterway, there will be a disposal of pollutants without a good streetwater management. However, streetwater can be a resource and allow it to nourish trees and soils on its path to ground or surface waters.
