Abstract

Flood is a major disaster in Balikpapan City. One of the locations experiencing high flooding is in the Damai settlement area (Ampal River Watershed), especially in Mayor Polisi Zainal Arifin Street. One of the causes of this flood-prone area is the suboptimal drainage conditions. This study aimed to assess the drainage services in the Damai settlement area (Ampal River Watershed), of Mayor Polisi Zainal Arifin Street to observe the drainage services and overcome flood problems. Achieving such goals was done by analyzing the service level of the drainage channel by using the scoring and weighting method. The scoring and weighting method produced classifications of drainage services in the Damai settlement area (Ampal River Watershed) on Mayor Polisi Zainal Arifin Street, namely, medium and bad drainage services. There is segment 2 channel 2A, segment 3 channel 3A, segment 4 channel 4A, and segment 5 on channel 5A and 5B classified as having bad service level and there are 13 channels classified as having moderate service levels.
