Abstract

ABSTRACT - Dense population settlements along riverbanks are a common problem that occurs in cities in Indonesia. Settlements along the riverbank are vulnerable to flooding. It is not easy to move residents from the area because of the strategic and economic value of the area for urban residents, especially the lower middle class. The purpose of this study is to find a solution for flood-prone areas by making settlement plans to minimize the impact of flood disasters.
The study was conducted in Cimacan, Haurpanggung Village, Tarogong Kidul District, Garut Regency. Research data collected by survey method. To get a history of floods that have been experienced by residents, questionnaires were used with the snowball method. Respondents taken were 22 respondents who had lived in 2 RWs for at least 5 years.
Based on the research results, it is known that the average flood height is 40-50 cm with the distance of water entering the settlement 50-60 meters from the river bank. The average number of houses submerged by floods is 40-50. To minimize the impact of losses from flood disasters, it is necessary to re-arrange the settlement space in Cimacan Village by setting green open space in the restricted zone to build houses, making infiltration wells and modifying residential building models. Model houses that are suitable to be built are like a stage house with a height of 60-70cm and a width of 30x30cm.
