This takes part in the predominance in urban competitiveness inspite of the potential pressure on accommodation and urban services need to be developed. These can be seen as the driving factor to the rapid urbanisation process particularly in suburbs which are actually the place for local ecological system . watercourse and vegetation referred to as the safety buffer against environmental harzards to ensure urban sustainable development. Relied on the engineering development in construction to change the natural environment many cities have seen several new development areas located on low-laying lands vulnerable to environmental attacks such as extreme floods. Addtionally this process will also exacerbate the increasing pollution of urban environment even potential trigger and spread of diseases. Hence the urbanisation and development of sub-urban areas need to be thouroughly considered from different viewpoints from the economic development versus environmental hazards. By using the results from the research published by Duy et al. 2017 2018 and Duy 2019 in cooperation with additional secondary data this paper blames potential environmental problems related to the uncontrolled urban concentration and urbanisation in suburbs. This allows an inform to the challenges to HCMC with the highlights in urban floods air and noise pollution and disease hazards in order to raise some .
