Living in an area prone to flooding can cause a host of challenges to homeowners. But did you know your landscaping can help proactively protect your yard? Read on for some smart landscaping features you can incorporate into your yard design to reduce the risks flooding poses to your property.

1. Purposeful Grading and Swales

Grading of your landscape helps direct water in specific directions. If you live in a flood-prone area, you’ll want to make sure the grading keeps rainfall away from your home’s foundation by sloping gently away from the house. That way, it won’t pool near the structure itself. Adding swales – which are shallow, elongated depressions that direct water away from vulnerable areas of your property – to your landscaping can help avoid flooding, too.

2. Permeable Surfaces

Impermeable surfaces in your landscaping may cause runoff issues. Replace traditional paved surfaces with permeable alternatives to improve water absorption on your property. Some permeable options include:

• Gravel driveways instead of asphalt or concrete
• Permeable pavers for patios and walkways
• Porous concrete for driveways and sidewalks
  

As water seeps through these materials, it’s effectively absorbed by the soil underneath and reduces surface runoff during heavy rainfall.

3. Flood-Resistant Plants

Another smart landscaping feature that can help when landscaping in flood-prone areas is choosing the right plants. Opt for native species that are well-adapted to local climate conditions and can withstand periodic flooding. 

Some excellent choices of flood-resistant plants include

• Ferns
• Daylilies
• Shrubs such as winterberry or Virginia willow
• Bottomwood trees such as elms, cottonwoods, and some maples.
  

These plants not only help stabilize the soil but also absorb excess moisture, making them assets for flood-prone properties.

4. Barriers

Landscaping features can also be used to serve as natural barriers against flooding. Here are a few stylish options you might consider

• Retaining walls: These structures can help manage water flow and prevent soil erosion on sloped properties.
• Berms: Raised, rounded areas of earth can direct water away from your home and protect low-lying areas.
• Dense hedgerows: Strategically planted shrubs and trees can slow down and absorb flood waters before they reach your home.

Scott Westfall, a top real estate agent in Virginia Beach, shares this insight: “In flood-prone areas like ours, smart landscaping not only provides curb appeal – it protects your investment. Incorporating natural barriers, rain gardens, etc. can mitigate flood risks while also enhancing your house’s long-term property value.”

5. Strategic Mulching

Choosing your mulch wisely can also impact your property’s resistance to flooding. Choose mulches like shredded bark or wood chips in your garden beds, which are heavier and can create a protective barrier against rain and soil erosion.

6. Effective Drainage Systems

One major factor in your home’s flood resistance is having a proper drainage system. Homes in flood zones need a system that is well-designed to manage the excess water the property is prone to hosting.

Consider implementing one or more of the following into your home’s drainage system

• French drains: These underground trenches filled with gravel help redirect water away from your home’s foundation.
• Catch basins: These structures collect and divert surface water to prevent pooling in low-lying areas.
• Downspout extensions: Direct roof runoff away from your home’s foundation by extending downspouts at least 5 feet from the house.
  

7. Rain Gardens

Rain gardens on properties prone to flooding are a great way to redirect and use all that extra water. They are shallow, depressed sections of landscaping designed to collect rainwater that runs off a roof, street, or driveway. Inside the garden, plant grasses or flowering perennials that thrive in moist areas, using porous soil to reduce flooding risks to the rest of your property. Rain gardens can also benefit your environment by providing a safe habitat for helpful birds and insects.

Cover Your Bases with Flood Zone Landscaping

There are a few other considerations when it comes to landscaping strategies for flood-prone areas. Local regulations need to be considered, especially if your property is part of an HOA. Some areas may have specific requirements for landscaping, so be sure to check with your municipality and consult experts if necessary.

You also want to make sure you have a plan for regular maintenance of your flood-resistant landscaping. Keep drainage systems clear of debris, trim plants regularly, and inspect your yard for any signs of erosion or water accumulation. By staying proactive, you can maximize the flood protection benefits on your property.

Conclusion

By implementing wise landscaping choices, you can significantly mitigate any flooding threats to your property. These strategies will help you protect your home and improve your landscaping’s beauty and functionality. With thoughtful planning and regular maintenance, your yard can be resilient and flourish even in flood-prone areas.
