Houston Flooding According to FEMA, there are 8 to 10 million households in floodplains (credit: weather.com).

HOUSTON—Throughout time, floods have altered the floodplain landscape. In addition, people have been historically attracted to bodies of water as places for living, industry, commerce and recreation. During early settlements, floodplains provided fertile soils for prime agricultural lands. Settlements emerged along rivers and other waterways for water and food supply, and access to transportation and recreational pursuits.
