Brownfield redevelopment is regarded as one of the most essential approaches to sustainable urban growth, as many cities suffer from a shortage of urban expansion regions other than agricultural areas, necessitating the optimum use of existing urban blocs. When we examine Egyptian cities, we discover a high demand for a brownfield approach in Egyptian delta cities. Because of the high value of agricultural land in exchange for expansion, as well as the huge demand of these cities to localize certain essential services, as well as the necessity of investors for plots of land, as well as to raise some environmental rates, such as the per capita share of green spaces. The main question for the research is: What is the executive framework for the Brownfield redevelopment applying to case studies as sample of the delta cities in Egypt? The research reviews the theoretical background on the brownfield approach. The research also discusses the analysis of brownfield from a sustainability perspective, with a review of the most important criteria, indicators, factors, phases and stages affecting the development of brownfield. Finally, the research is applied to the cities of Al-Mahalla al-Kubra and Kafr al-Zayat in the Delta to reach an executive framework for developing the brownfield in case studies. The research has identified several practical and implementable steps that can be applied to the case studies using the Brownfield approach. According to its unique characteristics, nature and considering its need for redevelopment and development of certain sites that are no longer utilized.
