Survey plans under DAO 2007-29 must depict which element to define property extents?

• A. Adjacent property boundaries
• B. Soil type
• C. Vegetation cover
• D. Land elevation

Answer: (A)

Defining property extents relies on fixed legal boundaries that anchor a parcel in relation to its neighbors. In a survey plan, showing the boundaries of adjacent properties provides the essential reference framework—bearings, distances, and corner markers that delineate where the subject land ends. This makes the extent of the parcel precisely locatable on the ground and reproducible for title description and registration, preventing encroachments and ambiguities.

So, adjacent property boundaries are the element that define the extent. Soil type, vegetation cover, and land elevation describe surface conditions or topography and do not determine the legal limits of a parcel. They may appear for context, but they don’t establish the boundary.
