Mapping period: September 11th until October 9th 2015
Surface area: 1.28 km2
Flood prone area: 0.35 km2 (27%)
Population (2012 census): 21,486
Total number of buildings: 4,021
Buildings at risk of flooding: 959, of which 1 is a school building.
Description and recommendations: As both the China and Kibangu rivers cut across Mzimuni in the south, where Mtambani and Mwinyimkuu subwards are located, most of the buildings along these rivers are frequently affected by flooding during the rainy seasons. The eastern part of the ward, home to Mwinyimkuu and Idrisa subward, is adjacent to the Msimbazi river, leaving most buildings there at high risk of flooding.
