Recent revisions to the DC Water Project Design Manual Volume 3 - Linear Infrastructure Design July 2018 require subsurface utility engineering:

“3.2 SUBSURFACE UTILITY ENGINEERING Utility designations shall be performed during design as described in CI/ASCE 38-02 to identify underground utilities. Unless otherwise stated, the minimum utility survey designation for locations anticipating excavation work shall be Level C. Level A is required when an excavation will be within 12 inches of an existing water or sewer utility. Level B is required for new water and sewer assets that will be located within two (2) feet of other buried utilities. Levels B and A may be required in other site(s) specific circumstances when directed by DC Water. “
