Examining the impacts of urban development on storm water drainage. A case of Eastleigh Section 1

This research project examines the impacts of urban development on storm water drainage in
Eastleigh Section I and this was undertaken to provide possible planning solutions that can be
implemented to solve the current problems associated with poor storm water drainage and in
addition to that address in the interrelated environmental, physical, social and economic
development challenges experienced in the study area.
The study sought to examine the impacts of urban development on storm water drainage and the
following specific areas were identified as key areas for examination in the light of the research
objectives: find out the nature of existing urban development in study area and how this affected
storm water drainage; existing drainage network, its location, spatial organization, operation and
its adequacy; examining the causes and effects of poor storm water drainage; identify the current
challenges facing planning and management of urban storm drainage in the study area and also
identify the policies and institutional framework which governs storm water drainage provision
and management and finally suggest possible planning interventions to address poor storm water
drainage system in Eastleigh section I area.
In the light of the set objectives the study established the key development challenges faced in
the study area which can be summarized as continued environmental degradation arising from
poor solid waste management and bursting of sewers, destruction of infrastructure facilities such
as road, gutter, curb, drains and sewer manholes, inaccessibility of properties and frequent
flooding nuisance among others. Problems related to poor storm water drainage was further
exacerbated by the weak institutional regulation, poor law enforcement, inadequate capacity
building and ineffective public participation in the planning and management of urban
infrastructure and utility services.
The study analyzed the secondary and primary data collected from the field and on the basis of
these findings a number of recommendations were put forward suggesting improvement and
expansion of key urban infrastructure and utilities services such improving road and drainage
network, upgrading water supply and sewerage system and at the same time adopting proper
solid waste management to solve key planning challenges associated with the poor storm water
drainage in Eastleigh Section I.
In the light of both findings and recommendations the study finds it necessary to conclude that
storm water drainage cannot be planned in isolation and recommends the adoption of integrated
approach to solve the poor storm water drainage currently experienced in the study area.
