Between 1950 and 2050, the share of the world's population that lives in cities is predicted to grow from 30% to 66%. This rapid urbanization has environmental consequences for local communities. Coastal slums especially deltas are one of the most affected areas by urbanization. The Nile Delta in Egypt is an example of such a growing area. In 2002, the International Coastal Road (ICR) was established north of the Nile Delta.
Due to its geographical location on the Mediterranean coast and AL-BURLLUS Lake, BURJ AL-BURLLUS city was affected by the (ICR) construction. (ICR) added a large area to the old city of BURJ AL-BURLLUS. The ICR had many positive effects locally and internationally, But if the (ICR)'s side effects are not avoided by well studying, the problems will be further complicated by another urbanization project like the proposed railway line.
The use of time series maps shows that the city of BURG ELBURULLUS is one of the cities that has undergone the most Environment and physical changes, since the area which is cut off from the lake and used as an extension of the city. The added area has reached half the area of the old city. The researcher's observation numerous changes in the new expansion area. The changes had significant impacts at all economic, social, and environmental levels, but the focus of the study was clearly on the environmental and physical impacts, then the research reaches to reflections of urbanization in environmental Impacts on Existing urban areas.
