What is the maximum angular closure for Suburban and Subdivision Property Surveys (Category II)?

The maximum angular closure for Suburban and Subdivision Property Surveys, categorized as Category II, is established as twenty-five seconds times the square root of the number of angles turned. This standard accounts for the precision required in suburban and subdivision surveys, where numerous angles are common due to the layout of residential developments.

As the number of angles increases, the acceptable angular error also increases, which is reflected in the formula that uses the square root of the number of angles turned. This method allows surveyors to standardize their measurements while remaining within the tolerable limits for accuracy. The choice of twenty-five seconds strikes a balance, providing a margin for error that is sufficiently tight for typical subdivision work, ensuring that the final results are reliable and can support further land development or property transactions.

Other options suggest different values, which do not align with the established standards for this category of survey, thus making them less suitable for this particular context.
