In the context of upgrading and widening the road network of Gaborone, Botswana, the impacts on the stormwater management are examined. In addition, it is proposed that the new lanes that will be constructed in the major roads of Gaborone can have a zero or even negative impact on the stormwater discharge and volume by employing improved and environmental-friendly stormwater management practices, by means of permeable pavement systems. Such systems will be combined with foot and bicycle paths that will be constructed adjacent to the major roads. In this report an overview of the proposed scheme is presented along with a description of the permeable pavement system, as a sustainable alternative for urban flood management, in treating urban runoff for water reuse and recycling. Based on sketchy information about the flood characteristics of Gaborone, rough estimations and guidelines for the hydrological and hydraulic design of the roadside drainage system are also provided.
