Building Encroachment on the Ntawogba Stormwater Drainage Servitude in Port Harcourt City, Nigeria
Settlement intrusion into natural stormwater servitude is an organic phenomenon that occurs in urban areas if unchecked. This study evaluates the encroachment of building developments on the Ntawogba natural stormwater drainage servitude in Port Harcourt. The study employs both quantitative and qualitative approaches. The study utilised a survey research methodology based on data obtained from a non-probability sample of forty (40) buildings selected purposively from the two-hundred and six (206) buildings observed as encroaching on the 15metres setbacks along the Ntawogba stormwater canal after a ground-truthing exercise and listing of buildings. Geographic Information System (GIS) was used for mapping the buildings within the stormwater servitude. Key informant data were obtained using a structured open-ended interview schedule from two (2) sources; the Director Building Plan Approval and Regulation and Director Development Control in the Rivers State Ministry of Physical Planning and Urban Development. The research found that the lack of stormwater management in the study area and extensive urban development particularly on wetlands due to the pressure of urbanisation and poor development control mechanisms were responsible for the 206 buildings on the stormwater drainage reserve. The study recommends that the stormwater sector plan of the Port Harcourt Master Plan, 1975 and the Greater Port Harcourt City Development Plan of 2009 to guide, monitor, control and manage the areas designated as stormwater servitude should be implemented to achieve sustainable urban growth and development. Agencies of Government should forthwith stop granting development permits to properties that fall within the stormwater servitude and the Rivers State Government should take steps to demolish all buildings encroaching on the Ntawogba canal to restore effective management and conservation of natural stormwater drainages.
