It explores the relationship between housing development and compliance with building and planning laws in the city. It uses a combination of quantitative and qualitative methods in examining possible factors that may have contributed to inner city settlements becoming slums. The findings show that factors such as sewage disposal, drainage planning, the condition of roads and solid waste management amongst others, have aided in determining the quality of urban environment and ultimately creating slums in Yenagoa. http://pubs.sciepub.com/jcd/3/1/7/jcd-3-1-7.pdf slums planning regulations environment waste disposal infrastructure
