By the time she corralled her children and pets, the quickly rising water rushed into her home. There was no time to collect or mourn her belongings as she ushered her frightened children and pets into the neighbors’ motorboat, travelled to dry land, found shelter, and contacted her family and friends to confirm their safety. As chaos unfolded around her, she spared no thought for the financial issues that would soon plague her. Now, as she stands in the wreckage of her living room in Baton Rouge, observing the musty smell and texture saturating her entire house and all of its contents, she realizes that she alone bears the cost of all that the flood destroyed. Her mortgage did not require flood insurance, and her house had never flooded before. If only she had understood the flood risk posed by the elevation of her house, she would have bought flood insurance. Days pass before family, friends, and volunteers can remove affected possessions and drywall. The pile of ruined materials in her front lawn is so high it blocks her view of the street. Her pile of debris is one of thousands lining southeast Louisiana streets. 1 The Louisiana August 2016 flood is the most damaging national flood event since Superstorm Sandy in 2012—affecting nearly 190,000 occupied houses and more than 6,000 businesses and 500,000 people. 2 The historic flood occurred because floodplain development blocked rainfall drainage of the Amite and Comite Rivers into Lake Maurepas, causing backwater Copyright 2018, by DERBIGNY WILLIS. 1. Baton Rouge Area Chamber (“BRAC”) estimated that in East Baton Rouge Parish, more than 110,000 homes and 2,055 businesses are located in flood areas with 32,857 housing units located within flooded areas.

To resolve these issues, Louisiana local 8 governments must adopt mechanisms to protect properties from flood risk and encourage homeowners to become more resilient against flood risk by purchasing flood insurance. This Comment seeks to eradicate public misconceptions regarding flood risk by clarifying flood terminology critical to understanding current legal and policy issues. Part I explains state and federal roles in flood mapping, flood insurance, and regulations in flood zones, 9 examines the East Baton Rouge Parish Metropolitan Council’s amended building code in response to the August 2016 flood, and discusses current litigation against the State of Louisiana alleging that construction exacerbated August 2016 flood damages. 10 Part II analyzes issues that expose properties to flood risk, including local governments’ failure to exceed federal regulations for floodplain management, incomplete flood mitigation projects, and public misconceptions about flood risk. Part III proposes solutions via local, state, and congressional action, ultimately advocating that Louisiana residents in any flood zone purchase flood insurance, irrespective of flood zone categorizations.
