Name one major legislation that significantly influenced land use planning in the United States.

The National Environmental Policy Act (NEPA) is a pivotal piece of legislation that significantly influenced land use planning in the United States. Enacted in 1969, NEPA established a framework for environmental protection during the planning and implementation of federal projects. One of its key components is the requirement for federal agencies to assess the environmental impacts of their proposed actions through the preparation of Environmental Assessments (EAs) and Environmental Impact Statements (EISs).

This process encourages agencies to consider environmental consequences and engage the public, fostering transparency and informed decision-making. By mandating that potential environmental impacts be evaluated, NEPA has played a crucial role in shaping land use planning practices across the country. It has created a legal context in which environmental considerations must be integrated into planning processes, ultimately promoting sustainable land use and development.

In contrast, other legislation listed may pertain to specific aspects of land use or development funding, but they do not have the same broad, foundational impact on the planning paradigm as NEPA.
