Berm
Definition and meaning of Berm in real estate.
A berm is a raised mound or barrier of earth, concrete, or stone designed to direct water runoff, prevent erosion, or act as a visual and sound barrier. In residential landscaping, it is often built to protect structures from flooding.
In more detail
Berms serve both functional and aesthetic purposes in property management and construction. When built near a driveway or garage entrance, a berm acts as a lip to prevent stormwater from entering the building. In larger residential developments, earthen berms are often landscaped with trees and shrubs to block highway noise and enhance privacy for homeowners.
Properly constructing a berm requires careful planning of drainage paths so that diverted water does not cause flooding issues for adjacent properties.

Frequently asked questions
Do you need a permit to build a berm on your property?
This varies by municipality, as changes to land grading can affect local drainage patterns and storm runoff, so checking local zoning codes is recommended.
How do you prevent a dirt berm from eroding?
Planting ground cover, grass, or shrubs on the berm helps bind the soil with root systems, and adding mulch or decorative stones reduces surface wear from rain.
