DESCRIPTION OF POTHOLE PROCEDURES

AIRX Utility Surveyors performs a full range of specialized engineering services including Underground Utility Location and Vacuum Excavation (to verify depth and alignment of underground utilities).

Underground Utility Location employs sophisticated electronic locating devices to trace the route of an underground utility; then the route is marked on the surface with marking paint in paved areas, or with 60 penny nails and feathers in unpaved areas.

Vacuum excavation employs a vacuum truck in conjunction with high-pressure air or water to excavate material and expose an underground utility. A 10 to 12-inch diameter hole is first cored or chiseled through the pavement so that the vacuum hose and high-pressure air or water hose can be inserted.

Utilities found during potholing are located on the surface by placing two reference points (typically 36” apart) on either side of the pothole along the centerline (or edge) of the utility, using paving nails or 60 penny nails as appropriate. Depth measurements (to the nearest ½ inch) are taken midway between the two reference points.

Utility alignment, depth, and other data is marked with pink paint (on pavement), or on wood lath (unpaved areas).

SITE SPECIFIC DETAILS

AIRX was contracted by County of San Diego to perform utility locating and potholing services on Japatul Road, Fuerte Drive, Campo Road, Conard Drive, Elmdale Drive, Jamacha Road, and Alta Drive in San Diego County. A total of 30 potholes were excavated, and 4 manholes were dipped to establish conflicts and connection points on a variety of utilities. The results of the data are contained in the attached spreadsheet and data sheets.

In preparation of these excavations, AIRX marked out the dig locations and called in for USA (Underground Service Alert). All traffic control plans and permits were drawn and applied for by AIRX and all traffic control was set up by

AIRX.

All the excavations and discovery went without any incident. Any changes and adjustments are mentioned in the Pothole Tabulation Report and the Pothole Data Sheets. All the results were annotated on the ground and in this report. It is AIRX’s recommendation that all pothole locations and the active mark out should be surveyed to aid in the adjustment of utilities on the final plan and profile.

At each pothole location, the utility alignment was marked with pink paint, as well as paving nails or feathers. AIRX used potable water acquired offsite for excavation and all water and material vacuumed was disposed of off-site. No water was allowed to flow into storm drains or natural drainages. The potholes were covered with clean backfill material and compacted to 95% density in 3” lifts. The pavement was patched with Aquaphalt All field work was performed between November 16, 2022, and February 9, 2023.
