Appraisal of development control activities in the peri-urban area of Osogbo metropolis, Nigeria.
The study identified and examined the activities of planning agencies involved in the development control of peri-urban area of Osogbo; assessed developers’ level of compliance with planning regulations in the development of the study area as well as identified and examined factors responsible for developers’ level of compliance with development control regulations with a view to evolving a policy guideline that could enhance the orderly arrangement of neighbourhoods in the study area. Both primary and secondary data were used for the study. Primary data were obtained from developers’ and heads of agencies in-charge of development control in the peri-urban area of Osogbo. Three (3) major peri-urban areas with clear boundary demarcation with Osogbo were selected for the study. These were areas along Osogbo-Ikirun Road in Olorunda Local Government Area; Ido-Osun and Ofatedo along Osogbo-Iwo Road both in Egbedore Local Government Area. Systematic random sampling technique was adopted in selecting residential buildings, from where developers were selected for survey. Reconnaissance survey revealed that there were a total of 4,941 buildings in the study area. These comprised 1,957 in Ayekale, 1,638 in Ofatedo and 1,346 in Ido-Osun. One out of every ten (10) buildings in each of the identified areas was surveyed. Using the above sampling procedure, 196, 164 and 135 buildings were selected from Ayekale, Ofatedo and Ido-Osun respectively. Information were also solicited from heads of Osun State Ministry of Lands, Physical Planning & Urban Development, Osun State Capital Territory Development Authority, Egbedore, and Olorunda Local Government Town Planning Authorities. Data collected were analyzed usingstatistical techniques such as frequency distribution, Chi-square, Analysis of Variance (ANOVA) Correlation Analysis and Factor Analysis. The study revealed that four different agencies were involved in the development control of peri-urban area of Osogbo. These are Osun State Ministry of Lands, Physical Planning and Urban Development, Osun State Capital Territory Development Authority, Departments of Town Planning and Land Services of Egbedore and Olorunda Local Government Areas. The various activities of these agencies included formulating and reviewing of town planning regulations, processing application for interim planning permit, approval of building plans, handling of appeals and petitions, preparation and design of development scheme, among others. The study established that developers’ level of compliance with planning regulations in the development of the study area varied as the socio-economic attributes varies. For instance, while the income of developers varied significantly in the study area (χ2 = 16.407 and p = 0.012), the period when developers submitted proposed development plan to agencies also differs in the three identified areas. The proportion of developers that submitted plans before embarking on construction in Ofatedo, Ido-Osun and Ayekale were 67.1%, 55.8% and 54.9% respectively. A total of 20.2% of developers in the study area violated planning regulation on approach set-back of building to the road. Using the Bivariate Correlation Analysis, the study revealed that the factors affecting Development control included absence of public enlightenment on the importance of development control (r = 0.332, p = 0.01), lack of data and information for decision making, lack of equipment and tools, inadequate skilled personnel and insufficient organisational structure for implementing development control (r = 0.316, p = 0.01). Others were insufficient legal framework, infiltration of corrupt and compromising officials, insufficient financial capability (r=0.333, p=0.01).The study concluded that development control activities in the study area were the sole responsibility of the identified government agencies.
