What is the "Base Line" requirement for a new subdivision?

The "Base Line" requirement for a new subdivision refers specifically to the need for accurate and reliable reference points for determining the layout and geometry of the subdivision. The correct answer highlights that two sufficient monuments must be set on a street line to establish this geometry for future surveys. Monuments provide physical markers that help surveyors maintain consistency between the current survey and any future work. This is essential in ensuring that property lines and boundaries are defined precisely, facilitating the development process and preventing disputes over land use.

In contrast, extending a line from the center of the main street or defining a boundary that indicates property lines does not inherently provide the necessary geometric framework that the base line requires. Similarly, a line indicating available utilities pertains to infrastructure rather than the foundational geometric setup essential for accurate subdivision surveying. Thus, the emphasis on setting clear monuments on a street line is crucial for maintaining the integrity of property boundaries and ensuring the proper orientation of the subdivision as it is developed.
