The project entitled “Improvement of trunk infrastructure outside Tan Hoa – Lo Gom Basin, Sectoral Project No. 5 & 6” is a sub project under Ho Chi Minh City, Urban Upgrading Project, Vietnam. This project is funded through a credit loan from the World Bank. The project covers 7 districts. (Districts 4, 8, 9, 12, Thu Duc, Go Vap and Binh Tan). Three of the districts are located in low-lying areas subjected to tidal influence. The design involves the assessment on the increase of rainfall intensity and tide level over the recent years due to climatic changes and land subsidence. The problems encountered in each area are unique and the solution required is different in order to suit the physical environment and development plan of each area. The challenges faced include working in congested areas with numerous utilities laid underneath roads without records. Extensive dialogues with residents displaced were conducted to draw-up resettlement action plan and environmental management plan.
