Conformity assessment to development plan implementation as a tool for development control in Kisii Town, Kenya
The objective of this study was to determine if the current land use development patterns in Kisii Town conformed to development zones in approved 1972 Kisii Town Physical Development Plan. Spatio-temporal analysis guided by Object Based Image Analysis (OBIA) was undertaken using QGIS software, integrating satellite image epochs of 2005, 2010 and 2017. Results showed that all approved development zones were not conformed to by ensuing land use development patterns, thus denoting nonconformity. The study also tested the hypothesis that there was no statistically significant difference between approved land use development patterns in the 1972 Kisii Town Physical Development Plan and ensuing land use development patterns in 2017. The test however found a significant difference between the two paired samples (M = 43.555, SD = 34.661) and (M = 36.344, SD = 34.047), t (9) = 4.03, p = 0.003. The null hypothesis was as a result rejected at 95% confidence level. The study concluded that because conformity to the development plan declined by a mean of 7.206, its objective as a tool for development control in Kisii Town was not attained. Recommendation was made that since the plan is outdated, a comprehensive plan covering the entire town should be prepared to provide a framework for development control. Additionally, there is need to adopt a strict enforcement and monitoring regime that ensures compliance with the plan.
