Flood By Numbers is a 100 sq-ft exhibit that highlights the devastating nature of flooding in the United States through the use of dynamic graphics, first person audio narratives and printed materials. By creating the Flood By Numbers exhibit, Acclivity Associates helps shoulder the task of communicating flood risks and highlighting the importance of flood mitigation.

Lives and property are at stake and Acclivity intends to compel individuals to act on their own behalf. The numbers say so much- floods are deadly and costly. Incredible amounts of people and resources must be deployed in response to major flooding. A wide range of factors and considerable energy goes towards flood mitigation.


Floods cause hundreds of deaths and billions of dollars in property damage in each year. When floods make the headlines, there is a heightened awareness about the dangers and losses related to the event. Yet when faced with personal choices regarding property and life, people still build on flood prone land, opt out of flood insurance, drive through flooded roads and allow children to play in flood waters. Behavioral change, particularly when danger does not seem imminent, is hard.

Despite this challenge, floodplain managers have implemented numerous policies and programs to help communities and protect the public.

More than 9,400 Certified Floodplain Managers throughout the country work to mitigate flood risks. Before, during and after the storm, they have proven themselves as invaluable community resources. They provide management guidance to community leaders, build awareness of flood prone areas, educate the public and participate on emergency response teams.

Through the implementation of local floodplain ordinances, floodplain managers prevent approximately $1.1 billion in flood damage each and every year.

Developing appropriate floodplain management means that planners and policy-makers must consider factors such as public safety, property protection, economic development and environmental conservation. In the 80-year history of federal flood control, engineered structures such as dikes, dams and levees were the primary physical solution to flood mitigation. Within the last 25 years, wetland and floodplain protection and restoration projects also have been shown to slow floodwaters as well as help to control erosion and maintain habitats. Today, flood policy has become a combination of built structures, natural protection, building ordinances, flood insurance and public education, a result of the complex needs of growing communities.
