The incidence of occasional flooding of an estate, a tank farm in Bonny Island, Niger Delta was investigated. The study was carried out to identify the remote causes of flooding and in turn proffer a solution. Detail field investigation involved identification of thirty-one roadside drains of rectangular cross-section; measurement of drains inverts (spot heights) at selected locations yielded estimates of longitudinal slopes (0.000416 – 0.0074 m/m), a case of very mild slopes. The invert profiles of 15 roadside drain indicated a case of inconsistent slopes, a mix of positive and negative slopes over short intervals, the observation accounts for siltation and ponding in the drains
