Which tool is most effective in preserving historic neighborhoods while accommodating new growth?

• A. A historic preservation overlay district.
• B. An environmental impact overlay.
• C. A general zoning overlay.
• D. A performance-based zoning approach.

Answer: (A)

Balancing preservation with growth relies on a zoning tool that adds targeted protections for historic resources while still permitting compatible new development. A historic preservation overlay district does exactly this by identifying historic resources, establishing design guidelines, and requiring review of changes to ensure the neighborhood’s character is preserved as new growth occurs. It can also provide incentives or streamlined processes to encourage preserving key buildings and streetscapes, making infill and renovations fit the historic context.

Other options focus on different aims. An environmental impact overlay targets environmental resources and may constrain development for ecological reasons rather than preserving historic character. A general zoning overlay is too broad to safeguard specific historic qualities. A performance-based zoning approach emphasizes outcomes but without explicit historic preservation standards, it may not reliably protect historic fabric unless preservation criteria are built into the performance requirements.
