Potholing means the practice of digging a test hole to expose underground utilities to ascertain the horizontal and vertical location of the facility.

Potholing means an excavation process that involves making a series of small test holes to accurately locate underground lines. Potholing is also known as daylighting.

More Definitions of Potholing

Potholing means a term used for the method of exposing an existing underground facility, by the means of hand digging, for the purpose of determining the facilities exact location.

Potholing means excavating the area above an underground facility to determine the precise location of the underground facility, without damage to it, before excavating within two (2) feet of the marked location of the underground facility, as required in Minnesota Statutes, Section 216D subd. 3a.

Potholing to expose other existing subsurface utilities during construction in order to maintain clearance and avoid damage to underground facilities during HDD installation activities is exempt from further review under this PA. 1. HDD installation of new infrastructure that occurs within the vicinity of other existing subsurface utilities require that the existing utilities be periodically exposed via excavation to ensure the new infrastructure does not conflict with existing utilities. The method of exposure is referred to as “potholing.” Potholing is required by code whenever new infrastructure is within forty-eight (48) inches plus half the diameter of an existing utility. Potholing involves removing an approximately nine (9)-inch-diameter soil column from the ground surface to the top of the existing utility via a vacuum truck. Potholing intervals are determined in the field and are conducted to the minimum extent necessary to ensure that new infrastructure maintains proper clearance from existing utilities. Potholing will typically occur within previously disturbed soils overlying the existing utilities, as most of the existing utilities requiring exposure are large enough to have required installation via mechanical trenching (e.g., water and sewer mains). Because potholing requires minimal ground disturbance and occurs only above existing utilities, there is minimal potential for this activity to adversely affect historic properties. Furthermore, areas to be potholed could not be archaeologically surveyed safely, and archaeological monitoring would be ineffective because the soil is vacuumed into a truck and the resulting hole is too small for adequate archaeological inspection. Therefore, potholing is exempt from further review under this PA.

Potholing pavement cores to expose existing utilities shall be made with an 18” diameter keyhole pavement core. Pavement core locations shall not be placed in the wheel path whenever possible. Vacuum excavation shall be utilized to expose underground utilities. Pavement cores shall be repaired within the same working day. The pavement core shall be retained and reused to fill the core hole.

Potholing. It is assumed that 8 potholes (4 feet x 4 feet x 6 feet deep) will be required. City approval is needed prior to proceeding with this task. Exact timing of the potholing will be coordinated with the City and may occur during a later project phase. Potholing will be performed by a subconsultant.
