This paper looks at flooding reduction through effective stormwater management strategy in urban areas. The management of urban stormwater has recently been recognized as a complex problem facing Local Governments and Urban areas all over the world. This has called for a more integrated approach to urban storm water management for urban areas and for all cities. The study was carried out with the main objective of establishing the effects of urban stormwater management strategy in reducing flooding in Mombasa County.

The challenges faced in urban stormwater management as found out include: inadequate planning in urban communities, Lack of stakeholder's participation and low level of community awareness in urban stormwater management. The data collected was analyzed quantitatively and qualitatively and was used to test the research findings. The results indicated that planning, stakeholders involvement and participation and public awareness and outreach campaigns greatly affects storm water management towards reducing flooding. It can therefore be suggested that from these three outcomes the storm water management may be said to have achieved envisioned and its long term impact of reducing flood risk. It is suggested that enforcement of policy and regulation on planning and development matters be given more attention and a more focused communication strategy need to be developed.

Public outreach and education campaigns further plays a pivotal role as the city management and county government often develop part of their education programs by considering more targeted information on particular topics. It is strongly recommended that an enhanced integrated stormwater management strategy be developed and be put into use for effective stormwater management for Mombasa County
