Preface
This is the first edition of CSA S250, Mapping of underground utility infrastructure.

Scope
1.1 General
This Standard specifies mapping requirements for the recording and depiction of underground utility infrastructure and related appurtenances at or below grade. This Standard does not apply to utility infrastructure that is normally above grade (e.g., overhead wires, pole-mounted transformers, antennas, and dishes).

1.2 Application
This Standard applies to proposed, existing, abandoned in-place, retired, or reserved for future use, underground utility infrastructure. This Standard applies to the generation, storage, distribution, and use of mapping records to ensure that underground utilities are readily identifiable and locatable. Application of this Standard will ensure that accurate information about the location and nature of the underground utility infrastructure is captured and available for future projects. See more
