What act establishes policies for the preservation of historic properties?

The National Historic Preservation Act of 1966 is the foundational legislation that established policies for the preservation of historic properties in the United States. This act created a framework for the identification, evaluation, and protection of historic resources, enabling federal, state, and local governments to collaborate in preservation efforts. It also established the National Register of Historic Places, which is essential for recognizing and protecting significant historic districts, sites, buildings, and landscapes.

Moreover, the act set forth programs and incentives to support preservation activities, including grants and tax benefits. It emphasized the importance of maintaining the cultural heritage of the nation, guiding communities in not only recognizing but actively preserving their historic assets. This legislation has played a crucial role in promoting awareness and stewardship of America’s cultural history.

The other options either do not correspond to actual legislation relevant to historic preservation or contain inaccuracies regarding the dates or focus of the acts, thus lacking the legal framework that the National Historic Preservation Act provides.
