Numerous government and non-governmental agencies are increasing their efforts to better quantify the disproportionate effects of climate risk on vulnerable populations with goal creating more resilient communities. Sociodemographic based indices have been primary source vulnerability information past few decades. However, using these fails capture other facets vulnerability, such as ability access critical resources (e.g., grocery stores, hospitals, pharmacies, etc.). Furthermore, methods estimate resource accessibility storms occur (i.e., in near-real time) not readily available local stakeholders. We address this gap by a model built strictly open-source data solve user equilibrium traffic assignment problem calculate how an individual's changes during immediately after flood event. Redundancy, reliability, recoverability metrics at household network scales reveal inequitable distribution flood's impact. In our case-study for Austin, Texas we found that most households least impacts floods experience volatile shifts metric values. Concurrently, quarter population often carries smallest burdens. show small moderate inequalities become large inequities when accounting communities' lower cope loss accessibility, carrying four times much burden quarter. The time developed can benefit emergency planning stakeholders helping identify require specific hazard events.
