Delaware’s unique geography makes it especially vulnerable to flooding and sea-level rise, placing the First State at the forefront of climate change impacts in the United States. As the lowest-lying state in the nation, Delaware faces growing risks from coastal storms, heavy rainfall, and rising tides that threaten homes, infrastructure, and communities across the state.
State leaders are using Delaware Flood Awareness Week to encourage residents to understand their flood risk and prepare for emergencies. The initiative highlights the importance of knowing evacuation zones, planning ahead for extreme weather events, and considering flood insurance to protect property and finances.
Delaware’s Low Elevation Increases Flood Risk
“As the lowest-lying state in the nation, Delaware is on the front lines of climate change and flooding,” said Governor Meyer. “I want to thank DNREC and DEMA for their partnership in leading Flood Awareness Week, helping Delawareans better understand their risks, prepare ahead of time, and protect what matters most.”
Because much of Delaware sits only a few feet above sea level, the state is highly susceptible to flooding from coastal storms, tidal surges, and intense rainfall. Rising sea levels are further increasing the frequency and severity of flooding events.
According to state officials, sea levels have risen more than seven inches in the past 30 years at one Delaware tide gauge. Combined with heavier precipitation and stronger storms linked to climate change, this trend is expected to expose more homes, roadways, and businesses to flood hazards in the coming decades.
“Know Your Zone” Campaign Helps Residents Prepare
Throughout Flood Awareness Week, the Delaware Department of Natural Resources and Environmental Control (DNREC) and the Delaware Emergency Management Agency (DEMA) are promoting the message “Know Your Zone.”
Understanding flood evacuation zones can help residents react quickly when severe weather strikes and prevent confusion during emergencies. Delaware residents can learn which evacuation zone they live in, work in, or frequently visit by using online tools provided by the state.
“Delawareans are already seeing more powerful storms and increased flooding because of climate change, and Flood Awareness Week is a time for people to understand their risks and be prepared. That education is one of the goals of our state’s Climate Action Plan,” said DNREC Secretary Greg Patterson.
Using the state’s flood planning resources, Patterson noted that he discovered his own neighborhood faces potential flood risk and that his family must be prepared to evacuate if authorities issue an order for Evacuation Zone D.
Flooding Is Delaware’s Most Common Natural Disaster
Emergency officials emphasize that flooding can happen quickly and with little warning, making preparedness essential for Delaware residents.
“Flooding is the most common natural disaster in Delaware, and it can happen with little warning,” said DEMA Director A.J. Schall. “Taking simple steps now can make a critical difference when severe weather strikes.”
Residents are encouraged to learn evacuation routes, sign up for emergency alerts, and review evacuation planning resources available through the state’s preparedness website.
Officials also stress that flood insurance is an important financial safeguard, even for homeowners and renters who do not live in designated high-risk flood zones. Standard homeowners insurance policies typically do not cover flood damage.
Educational Resources and Webinar Available
As part of Flood Awareness Week, DNREC will host an educational webinar titled “Top 3 in 30,” which will highlight the most important floodplain management and planning information residents should know in just 30 minutes.
The virtual webinar is scheduled for Thursday, March 19 at 2 p.m., and will provide practical insights on understanding flood risk and using Delaware’s flood planning tools.
Climate Change Driving Future Flood Challenges
Delaware’s updated Climate Action Plan outlines how climate change is expected to intensify flooding risks statewide. Rising sea levels, increased coastal erosion, and more frequent heavy rainfall events could overwhelm drainage systems and expose additional neighborhoods to flood damage.
For new residents and homebuyers considering relocation to Delaware, understanding local flood risk is an important step in choosing a property and preparing for extreme weather events.
State officials hope Flood Awareness Week will encourage residents to take proactive steps that improve safety and resilience across Delaware communities.
By learning evacuation zones, understanding flood risks, and considering flood insurance coverage, Delaware residents can better protect their homes, families, and investments in a state where water and weather will increasingly shape the future.
