Final answer:
Street addresses are not a legal description used in Iowa; instead, the state utilizes metes and bounds, government survey system, and reference to a recorded plat for defining property boundaries.
Step-by-step explanation:
The legal description that is NOT used in Iowa is a street address. Legal descriptions of property are essential for identifying property boundaries and are a matter of public record. The three common legal descriptions used in Iowa include metes and bounds, government survey system, and reference to a recorded plat. The metes and bounds system dates back to English settlers during the colonial period and involves describing plots of land using natural landmarks such as trees, rocks, and streams. These would be registered with government authorities to establish legal claims to the land. However, the system's reliance on impermanent landmarks can lead to difficulties in establishing precise boundaries.
