Flood Factors across Volusia County.
A property's Flood Factor is an indicator of its comprehensive flood risk, ranging from 1 (minimal) to 10 (extreme). Properties with higher Flood Factors are more likely to flood.
Volusia County has likely experienced flooding in the past.
Based on a recreated model of the flood, 551 properties in Volusia County were impacted by Hurricane Irma in September, 2017. Learn more about historic floods.

Flood risks vary by depth and likelihood
Deeper floods from major events, like hurricanes, are less likely to occur, but cause greater damage than more shallow flood events, like heavy rains.

Environmental Changes
Flood risks are increasing because of the environment.
A changing environment means higher seas, new weather patterns, and stronger storms. As the atmosphere warms, there is more evaporation and more water available when it rains.
A warmer atmosphere also means warmer oceans, which can intensify flooding from hurricanes and offshore storms. Sea level rise also increases coastal flood risks, as higher seas mean there's more water available when high tides and coastal storms cause flooding.

Community Solutions
There are solutions to protect this area.
Although flood risk can never be completely eliminated, communities that adapt to higher flood risks can limit flood damage and lower flood insurance costs. Learn more about solutions.
Green infrastructure is a cost-effective and sustainable flood management approach that gathers and removes water at its source.
Open Spaces
By providing space for managed flooding, communities can reduce the flood risks for homes and businesses. These spaces can include cemeteries, golf courses, and parks.
Marshes and Wetlands
Restoring or constructing new marsh or wetlands provides areas for water to be stored, therefore reducing flooding.
Rain Gardens and Bioswales
Rain gardens reduce flash flooding by collecting rainwater and allowing time for the water to be absorbed or carried away. Bioswales are larger but functionally similar, and usually a part of a larger stormwater drainage system.
Beach Dunes and Renourishment
Beaches and dunes work as natural walls to reduce the impact of storm surges. Adding sand to make beaches bigger helps limit coastal erosion and protect communities from flooding.
Natural Barriers
Restoring and building up natural infrastructure such as barrier islands, oyster and coral reefs, mangroves, seagrass, and salt marshes is a cost-effective and eco-friendly way to reduce flood risks.
