Evaluation of Plan Implementation: Peri-Urban Development and Diobu Layout plan, 1975-2018

This work is on the implementation of Diobu Layout plan of 1975 to 2018 with a view to examine if the actual spatial development in the area conforms to the prepared plan from the plan implementation perspective. Both primary and secondary sources of data were employed. The primary data were gotten via the use of direct observation; interview granted to selected key informants and ground trotting of existing development status of the area. The secondary date used included satellite imageries from both Landsat and Google. The result of the analysis revealed sharp deviation in development among the different land uses leading to amorphous and uncoordinated growth contrary to the Master plan prepared for it. These deviations can be understood in the context of rapid population, economic growth and response to market forces. Spatial expansion of Diobu settlement greatly precipitates the formation of new districts, changing the morphology of the area, thus posing serious concerns of urban threshold, but not without some consequences. The study advocates for stricter enforcement measures in line with existing development control legislations and regulations. Ensuring that development complies with land use regulations therefore requires periodic and regular field visits and/or site inspections. This is the only practical way to ensure that proposed development in Diobu conforms to stipulated guidelines for urban development planning of the area.
