In civil and surveying practice, which specific drawing or mapped document is created to show property lines, lot boundaries, dimensions, and related information used to calculate areas and locate building projects and facilities?

Introduction / Context:
Land development, permitting, and construction layout rely on accurate legal and geometric descriptions of parcels. The drawing that formally records lot divisions, boundaries, easements, and related survey data is foundational to planning and design.

Given Data / Assumptions:

• We need a mapped document that shows property lines and supports area calculations.
• The drawing must help locate building projects and facilities with respect to legal boundaries.
• We distinguish among traverse notes, contours, general city maps, and plats.

Concept / Approach:

A plat (or plat map) is a legal map drawn to scale that documents subdivisions, lot lines, public ways, easements, and other boundary information. Plats are recorded to establish ownership delineation and form the basis for calculating lot areas and siting structures within setbacks and zoning constraints.

Step-by-Step Solution:

Verification / Alternative check:

Surveying practice distinguishes field traverse data (measurements and bearings) from the finalized recorded plat. Contour or city maps lack the legal precision for property lines required for permitting and deeds.

Why Other Options Are Wrong:

Traverse: refers to a sequence of measured lines used during surveying; it is raw or intermediate data, not the finalized legal map.

Contour: shows equal elevations, useful for grading but not for legal property delineation.

City map: gives broad geographic context but typically does not establish legal parcel boundaries.

Common Pitfalls:

Confusing topographic maps with plats. While both are to scale, only the plat establishes legal boundary descriptions needed for deeds and permits.

Final Answer:

Plat
