Terrain Characteristics and Planning Challenges for Stadia Infrastructure in Deltaic and Coastal Environments in South-South Region of Nigeria

Abstract

Building large sports facilities in deltaic and coastal areas presents significant planning challenges due to the specific characteristics of the land. This research investigates the viewpoints of professionals regarding the impact of terrain on stadium planning choices, developmental limitations, and performance results within Nigeria's South-South region. It employs a qualitative comparative methodology, drawing on physical, environmental, and institutional planning considerations. This study uses a qualitative research approach, relying on secondary data analysis. The data comes from geotechnical reports, environmental impact assessments , planning documents, satellite images, and existing academic and policy sources. Four stadiums in the South-South region were chosen for this study. They were selected to represent a variety of environmental conditions, including low-lying areas prone to flooding, land that had been reclaimed, swampy soils, and slightly elevated terrains. Thematic analysis and cross-case comparison were used to examine the data. This helped identify the main challenges related to the terrain and their effects on the results of the stadium planning. The results show five common land features that affect stadium construction: unstable soil, high groundwater levels, a risk of flooding, ecological sensitivity, and limited natural drainage. The terrain's features significantly influenced the planning decisions about foundation systems, site preparation costs, construction schedules, maintenance needs, and the facility's long-term performance. The research also highlights distinct professional priorities: planners and architects prioritize site suitability and land-use compatibility; engineers concentrate on soil stability and structural safety; environmental regulators emphasize ecosystem protection; and project owners are chiefly concerned with cost overruns and project viability. The comparative examination of the case studies reveals that stadiums situated on well-drained or moderately elevated land demonstrated enhanced construction efficiency, reduced maintenance requirements, and increased operational resilience relative to those built on reclaimed or flood-prone locations. The results highlight a significant correlation between planning strategies that respond to the terrain—specifically, thorough site investigation, adaptable foundation design, and integrated drainage planning—and enhanced stadium functionality, longevity, and environmental performance. In conclusion, the study's results indicate that the characteristics of the terrain significantly affect the results of stadium planning in Nigeria's South-South region. Building stadium infrastructure that can withstand environmental challenges and is sustainable requires a careful approach. This involves using design principles that consider the terrain, conducting thorough geotechnical assessments early in the project, and following planning policies that are specific to the local context. The research suggests that IIARD International Journal of Geography & Environmental Management planning authorities should enforce strict site evaluation standards. It also recommends that design professionals use solutions that adapt to the terrain, and that policymakers create guidelines specific to each region to guide stadium development in Nigeria and similar deltaic areas.
