Spring Snow Melts and Flooding - Protecting Your Property in a Changing Climate

As spring approaches in Southeastern Michigan, the familiar thaw of winter snow brings renewed warmth—but also increased risks of flooding. The combination of snowmelt, heavy rainfall, and aging infrastructure has made flooding a recurring issue across the region, especially as climate change intensifies weather patterns. For Ann Arbor residents, understanding the history of flooding, how to protect your property, and what to do if you experience flooding is key to staying prepared.

The History of Flooding in Southeastern Michigan

Flooding has long been a challenge in Southeastern Michigan, but recent years have shown an uptick in both frequency and severity. Cities like Ann Arbor, Detroit, and Dearborn have all faced catastrophic floods, with the June 2021 storms serving as one of the most devastating examples. That storm dropped nearly 7 inches of rain in some areas, overwhelming stormwater systems and flooding thousands of homes.

In Ann Arbor, neighborhoods like Pittsfield Village and parts of Southeast Ann Arbor were hit particularly hard. As climate change continues to cause more extreme and unpredictable weather, experts predict that these kinds of events will become more common.

Why Is Flooding Getting Worse?

Climate change plays a significant role in the increased risk of flooding in Michigan. Warmer temperatures lead to more intense storms, heavier rainfalls, and faster snowmelt—factors that strain stormwater systems not built to handle such large volumes of water. Additionally, urban development can reduce natural drainage areas, making flooding worse in certain neighborhoods.

What Neighborhoods Are Most at Risk in Ann Arbor?

Some neighborhoods in Ann Arbor are more prone to flooding due to their location, topography, and infrastructure.

Southeast Ann Arbor (Pittsfield Village): Experienced major flooding during the 2021 storm, prompting city investigations into drainage improvements.
Downtown Ann Arbor: Low-lying areas with older stormwater systems are at risk during heavy rains.
West Ann Arbor: Certain pockets are vulnerable due to their proximity to natural creeks and wetlands.
Floodplain Zones: Properties near the Huron River and other bodies of water are naturally at higher risk.

The City of Ann Arbor provides updated Flood Insurance Rate Maps (FIRM) to help residents determine if their property falls within a floodplain.

How to Protect Your Property from Flooding

While flooding can't always be avoided, there are proactive steps you can take to reduce damage:

Install a Sump Pump: A sump pump with a battery backup can remove water from your basement during heavy rains.
Waterproof Your Basement: Seal cracks in foundation walls and apply waterproof coatings to reduce leaks.
Clear Gutters and Drains: Regularly clean gutters and downspouts to ensure proper drainage away from your home.
Elevate Appliances and Electrical Systems: Raise furnaces, water heaters, and electrical systems above potential flood levels.
Landscape for Drainage: Use native plants and grading to improve water flow away from your property.

What to Do if You Experience Flooding

If flooding does occur in your home or neighborhood, it's important to act quickly:

Ensure Safety First: If water levels pose a risk to life, call 9-1-1 immediately.
Report Flooding: Contact the Washtenaw County Water Resources Commissioner at 734-222-6860 for street flooding and drainage issues.
Document Damage: Take photos and videos of all damage for insurance purposes.
Contact Your Insurance Company: Report the incident as soon as possible to start the claims process.
Professional Cleanup: Hire certified restoration companies like Restoration 1 of Ann Arbor or SERVPRO of Ann Arbor to handle water extraction and mold prevention.
Well Water Testing: If you rely on a private well, contact the Environmental Health Division at 734-222-3800 to test for contamination.

Preparing for the Future

With climate change driving more extreme weather, flooding will continue to be a growing concern in Ann Arbor and across Southeastern Michigan. The City of Ann Arbor is working on stormwater management improvements, but homeowners must also take responsibility for protecting their properties.
