Road and Urban storm water drainage integration: to understand the level of integration between urban road and storm water drainage facilities

In Ethiopian cities/urban centers the attention towards urban storm water drainage is very low. This work gives an emphasis to storm water drainage management-as storm water/urban flooding increase with urbanization. Also this study needs to concentrate on sustainable storm water management instead of the conventional ones due to its numerous advantages. This is to mean the attention to on-site infiltration should be emphasized. The use of grassing-in general porous structures will encourage on-site infiltration by reducing urban flooding. urbanization in general leads to deforestation. Deforestation along with impervious structures in urban centers reduces the infiltration capacity a land. Thus, to properly manage storm water in a given urban area municipalities should emphasize on sustainable storm water drainage management than the conventional one, which is concentrate on the use use of solid or impervious structures.
