The growth of Banda Zone B1 & B3 has over time been characterized by informal and unplanned settlements. As a low-lying urban area between Kireka hill and Banda hill, Banda Zone B1 & B3 has over many years experienced floods that are a result of high intensity rainfall which has often caused storm water runoff that exceeds the capacity of the current drainage system.

The main objective of this project is to assess the causes of the flooding in Banda Zone B1 & B3 and to come up with integrated flood mitigation and adaptation measures.

Since most of the settlements in Banda Zone B1 & B3 are informal and unplanned, this project takes up a scenario approach when estimating floods in flood modeling. The scenario approach takes into consideration the current state, possible and future scenarios of development in the area when modeling floods.

An integrated flood risk mitigation and management plan for Banda Zone B1 & B3 was achieved basing on the modeled floods in PCSWMM. In relation to the various scenarios of development in the area, drainage systems were then proposed for each of the scenarios and presented in this report. The total discharges at the outfall were also presented and used to compare the different scenarios of development.
