A recent study by Akagwu, et al., (2024) titled “INVESTIGATION OF SUSTAINABLE URBAN DRAINAGE UTILIZATION IN RESIDENTIAL PLOTS IN AMUWO-ODOFIN, LAGOS, NIGERIA” published in the Journal of African Innovation and Advanced Studies shows residential plots do not follow approved design setbacks during development, leading to limited open spaces covered with impervious materials.

Non-compliance with setback regulations limits open spaces, hindering effective SUDS implementation and compromising urban sustainability in Amuwo-Odofin– Akagwu, et al., 2024
The article explores the implementation of Sustainable Urban Drainage Systems (SUDS) in residential areas of Amuwo-Odofin, Lagos, Nigeria. The primary focus is on integrating SUDS into site planning for residential plots to enhance environmental sustainability. The study delves into how SUDS can be effectively utilized within residential plots to manage stormwater, reduce flood risk, and promote sustainable urban development. It emphasizes the importance of incorporating SUDS in the initial stages of site planning and development.
How the Study was Conducted
The study focused on residential plots in three categories of estates in Satellite Town. The total research population was 1,343 residential plots. A sample size of 567 residential plots was calculated using a sample size calculator with a 95% confidence level and a 5% confidence interval. The authors employed data through questionnaires distributed to the house heads of the selected residential plots. The questionnaire was divided into four subsections to gather information on social status, residential site plan, SUDS status, and effects and perceptions of SUDS. The authors sorted collected data and analyzed using the Statistical Package for Social Sciences (SPSS) Version 21. Spearman correlation analysis was employed to assess the relationship between site setbacks and SUDS potential.
What the Authors Found
The authors found that most residential plots do not follow approved design setbacks during development, leading to limited open spaces covered with impervious materials. In addition, the author posits that increasing setback distances within residential plots can create more opportunities for Sustainable Urban Drainage Systems (SUDS) implementation.
Why is this Important
Urban Sustainability: By examining the utilization of Sustainable Urban Drainage Systems (SUDS), the study contributes to urban sustainability efforts. SUDS help manage stormwater runoff, reduce flooding, and enhance water quality in urban areas.
Environmental Impact: The research highlights the impact of setback distances on open spaces within residential plots. Increasing these distances can lead to more unpaved areas, promoting natural elements and biodiversity.
Policy Implications: The study’s recommendations emphasize government enforcement of setback regulations and education about the importance of SUDS. Implementing these recommendations can enhance urban planning and environmental resilience.
What the Authors Recommend
The authors recommend that the government should strictly enforce setback distance regulations to ensure adequate unpaved areas are maintained within residential plots. Additionally, it suggests the introduction of natural elements, such as vegetation and permeable surfaces, into these unpaved areas. This approach would not only enhance the aesthetic value of residential environments but also improve their ecological sustainability by facilitating natural water infiltration and reducing surface runoff.
In conclusion, the study by Akagwu et al. underscores the critical importance of adhering to setback regulations and integrating Sustainable Urban Drainage Systems (SUDS) in residential plots to foster urban sustainability in Amuwo-Odofin, Lagos. By ensuring adequate unpaved areas and promoting natural elements within residential environments, cities can significantly enhance stormwater management, reduce flood risks, and improve ecological resilience. The research highlights a vital pathway towards sustainable urban development, emphasizing the need for strict enforcement of setback policies and public education on the benefits of SUDS. Implementing these measures will not only enhance the aesthetic and environmental quality of urban areas but also contribute to a more sustainable and resilient future for rapidly growing cities.
