Question

what is a key reason for zoning regulations in land use planning?
to raise construction costs
to limit public access to land
to enhance short - term profitability
to reduce environmental impacts

Explanation:

Zoning regulations in land use planning are typically aimed at managing land use to achieve various goals. Raising construction costs (first option) is not a key reason as regulations usually seek reasonable development. Limiting public access (second option) is not a primary goal; land use planning often considers public access appropriately. Enhancing short - term profitability (third option) is not a key reason as zoning is more about long - term, sustainable land use. Reducing environmental impacts is a key reason as zoning can separate incompatible land uses (e.g., industrial and residential) to protect the environment, manage resources, and promote sustainable development.

Answer:

D. to reduce environmental impacts
