Measuring Flood Stigma: The Case of Harris County and Hurricane Harvey

In recent years, the Upper Texas Gulf Coast has been the subject of catastrophic flooding. Tropical Storms ranging from Allison to Harvey and recently Imelda have wreaked havoc on the Houston Area. Flooding in Houston is not restricted to Tropical Cyclones but other intense down pours continue to highlight the vulnerability of drainage in the area. Consequently, inundated homes and lake freeways have become the symbol for property loss in Houston. Amid a thriving real estate market, the frequency of flooding and the limited impact of a frail migration process is an ongoing concern. The central thesis is how is the housing market responding to these cataclysmic flooding events?

This paper examines the impact of flooding on real property values in Harris County, Texas. The analysis is done on residential single family property. Using sales price of single family houses before and after hurricane Harvey, a hedonic model is used to measure the impact. The paper outlines Harris County single family housing inventory exposure to flood hazard areas. The result shows that the housing market is recovering from the devastation. However, repaired flooded houses are selling for less in comparison to non-flooded houses in similar condition.
