The NFIP is often referred to as a “three-legged stool”, meaning there are 3 different parts that help support the program – Flood Insurance, Floodplain Development Regulations, and Floodplain Maps.

Some methods of flood control have been practiced since ancient times. These methods include planting vegetation to retain extra water, terracing hillsides to slow flow downhill, and the construction of floodways (man-made channels to divert floodwater).

Forms of Flood Mitigation They include floodwalls/seawalls, floodgates, levees, and evacuation routes.

Some of the common techniques used for flood control are installation of rock berms, rock rip-raps, sandbags, maintaining normal slopes with vegetation or application of soil cements on steeper slopes and construction or expansion of drainage channels.

Methods of control of flooding are as follows:

• Control the water level dams check dams.
• Build barriers(Levees) embankments flood walls.
• Alter the river's channel Straighten it Widen and deepen it.
• Control land use around the river (land use zoning)
• Flood embankments.
• Floodways.

Levees, Dams, Dikes, and Weirs These barriers, often built along rivers, help regulate water levels or flows and prevent flooding.

Control of Floods. Some methods of flood control have been practiced since ancient times. These methods include planting vegetation to retain extra water, terracing hillsides to slow flow downhill, and the construction of floodways (man-made channels to divert floodwater).

1. To reduce the risks from flood and channel migration hazards. 2. To avoid or minimize the environmental impacts of flood hazard management.

What Causes Floods?

• Heavy rainfall resulting from tropical weather disturbances.
• Deforestation.
• Improper agricultural practices.
• Inadequate design of drainage channels and structures.
• Inadequate maintenance of drainage facilities, blockage by debris brought by flood waters.
• Construction of settlements in flood plains.

Explore structural improvements

• Stormwater pumps. With higher seas, water doesn't drain out as easily.
• Upgrade roads and bridges.
• Improved stormwater drainage systems.
• Flood control measures.
• Levees, Dams, Dikes, and Weirs.
• Tide and Flood Gates.
• Seawalls and Floodwalls.

Forms of Flood Mitigation They include floodwalls/seawalls, floodgates, levees, and evacuation routes. Nonstructural measures reduce damage by removing people and property out of risk areas. They include elevated structures, property buyouts, permanent relocation, zoning, subdivision, and building codes.

Flooding is an overflowing of water onto land that is normally dry. Floods can happen during heavy rains, when ocean waves come on shore, when snow melts quickly, or when dams or levees break. Damaging flooding may happen with only a few inches of water, or it may cover a house to the rooftop.
