Urban development is considered one of the most sustainable development pillars. It focuses on enhancing the quality of life for local communities. When new urban districts are attached to heritage districts, the communities of the new districts make greater impact on the heritage districts. This is where it gets complicated, since a strict balance is needed to apply urban development while conserving the heritage districts themselves. Many heritage sites have a great problem, which is urban interference with the heritage zones at site borders. This is what happened in The Pyramids heritage district, which was affected by The Pyramids Gardens neighborhood and Kafr El Gabal, Kafr Ghataty and Nazlet El Seman areas. This resulted into urban pressure on the infra-structure, causing negative impact on the heritage site. This is the main research problem, while the research objective is to make an assessment to manage urban districts, which are attached to heritage districts. The proposed management approach can balance between development and conservation, by following the approach of analytic study.
