The Indonesian disaster board also noted that flood events has increasing pattern for today and future ...time. One of the strategic ways to decrease the impact of flooding is delivering the emergency infrastructures to the needs immediately. The faster delivery makes less impact of disaster events. Therefore, this paper synthesizes a rapid model of assessment from the full assessment of emergency infrastructure need in Sidoarjo Flooding 2020. During the synthesize, the model can reduce duration of assessment from 148 days to four days only. Within the time, eight main steps include finding relevant emergency infrastructures, determining emergency infrastructures needed, assessing emergency infrastructures needed and confirming the actual emergency infrastructure needed. Those eight steps should be taken by encouraging more FGD and in-depth interviews for key relevant stakeholders, guided by specific checklist and filling the gap forms. Strict forms and guidelines provided to help the process in achieving four days assessment period. Consequently, the authorities can use the output assessment for emergency infrastructure program delivery starting from the fifth days after the events.
