(3.4) “Gravity-fed system” means any underground facility that is not pressurized and that utilizes gravity as the only means to transport its contents. These systems include sanitary sewer lines, storm sewer lines, and open-air irrigation ditches.

(6.7) “Subsurface utility engineering notification” means a notice to the notification association that a project is being designed by a licensed professional engineer and that the project will include the investigation and depiction of existing underground facilities that meet or exceed the ASCE 38 standard.  (6.8) “Subsurface utility engineering-required project” means a project that meets all of the following conditions:   The project involves a construction contract with a public entity, as that term is defined in section 24-91-102;    The project involves primarily horizontal construction and does not involve primarily the construction of buildings;      The project: (c) (I) The project:   Has an anticipated excavation footprint that exceeds two feet in depth and that is a contiguous one thousand square feet; or    Involves utility boring.       For purposes of this subsection (6.8)(c), the term “two feet in depth” does not include rotomilling, and the contiguous one thousand square feet does not include fencing and signing projects.       The project requires the design services of a licensed professional engineer.
