Surabaya, the second largest city in Indonesia, is highly vulnerable to flooding due to its physical typology and inadequate drainage infrastructure. The city's vulnerability is exacerbated by the limited open space to accommodate and infiltrate rainfall runoff water, causing further environmental impacts. This thesis aims to develop a comprehensive flood management plan for Surabaya, focusing on the integration of Water Sensitive Urban Design (WSUD) principles to reduce flood risk in highest floodprone area. This thesis addresses comprehensive flood risk mapping and explores suitable WSUD elements to effectively manage stormwater in areas of highest flood vulnerability area in Surabaya City. This thesis uses a multicriteria spatial analysis approach to identify flood-prone areas in Surabaya using the latest data, identifies appropriate WSUD elements to be adapted to the inventory data of physical, policy, and biological conditions in the study area based on LaGro's (2007) method, and uses volume raster analysis to determine flood storage needs so that it is known how much and what WSUD elements to use. The methodology includes the development of a landscape planning strategy to control flooding in one of the most flood-prone areas, which adapts WSUD elements to local policies and adjusts based on the results of spatial analyses so that what is applied will be relevant to the conditions and policies in the study area so that the method carried out in this planning provides an example for integrating WSUD concepts into policies and conditions specifically in Surabaya. The planning results show that the application of WSUD elements can contribute to providing flood water storage of 148,500.00? m?^3, exceeding the capacity requirement 23.883,4? m?^3, creating new public green spaces amidst the dense development of built areas of the City. The study provides a model for flood control planning in Surabaya, demonstrating the potential of WSUD in creating sustainable and resilient urban environment.
