Abstract
Addis Ababa is currently undergoing city wide transformation with respect to its built environment
and provision of basic infrastructure services. Local street construction with cobblestone pavement is
one of the infrastructure development implemented in every part of the city. However, the
constructed local streets in many parts of the city are deteriorating within a short time after
construction. Therefore, the main objective of the study is; to device green infrastructure design and
technologies for the local streets of Addis Ababa in order to reduce the impact of stormwater runoff
and at the same time to enhance environmental quality of the city neighborhood.
In order to accomplish the objective, research methods were developed for each specific objective.
Case study method is then used in the research, by selecting two areas in Addis Ababa that are found
in the same local watershed, based on appropriate criteria. Consequently, the existing situation of
local streets and impact of stormwater runoff in the study areas is analyzed.
Based on the research findings, the research proposes site specific green street design and
technologies for the local streets of the study area. Moreover, the research tested and illustrated the
upscale effect of green infrastructure practices on watershed level using Arc GIS platform.
