Which term describes zones created to separate incompatible land uses?

• A. Nonconforming Use
• B. Spot Zoning
• C. Environmental Protection Laws
• D. Buffer Zones

Answer: (D)

The idea here is about creating space between land uses that don’t mix well in order to reduce conflicts like noise, glare, pollution, or safety concerns. A buffer zone is exactly that: a designated area placed between incompatible uses, often featuring landscaping, fencing, or setbacks, to soften the transition and protect sensitive nearby activities.

Buffer zones act as a screen or barrier, slowing any negative impacts from one side so nearby uses—such as homes adjacent to a commercial, industrial, or high-traffic area—aren’t directly exposed. They’re about separation and mitigation, not about changing a property’s use or granting special treatment to a single parcel.

Nonconforming use refers to a longtime established use that continues after zoning changes, not about creating separation between uses. Spot zoning describes giving a single property a distinct zone that diverges from the surrounding pattern, which is separate from the concept of a general protective margin. Environmental protection laws govern safeguarding natural resources and public health, but they aren’t specifically about zoning away incompatible uses with a dedicated buffer area.

So, the term that fits is buffer zones: areas designed to separate incompatible land uses and mitigate their impacts.
