Results showed the businessmans generally realize that their business location prone to flooding, however not all have the high desire to do something to mitigate flood risk. Respondent tend to expectfrom government program. Estimation results of total structural damages assessment is Rp 258 908 010 and total losses value is Rp 545 848 100. If normalization program goes well and with the assumption can reduce the average height of flood inundation until 72.72% of previous, then total losses value will decrease to 42%. If it can reduce the average flood duration until 96.84% of previous, then total losses value will decrease to 61%. Results of flood vunerability analysis showed that small scale bussiness units are more vulnerable to flooding, and bussines units located in Rawa Buaya are more vulnerable to flooding if related to the flood duration, whereas bussines units located in Kedoya Selatan are more vulnerable to flooding if related to inudation.
