DESCRIPTION OF POTHOLE PROCEDURES
:
AIRX Utility Surveyors performs a full range of services including Utility Locating, Vacuum Excavation
to identify the depth and alignment of existing utilities, Video Inspection services and Subsidence
Monitoring.
When employed Utility Locating establishes an alignment beneath which the desired utility has been
traced. To convey this information to crews that follow mark outs are done using paint, nails or feathers
with appropriate annotation. On hard pavement AIRX uses white paint to identify the intended utility
while utility locators use paint of the appropriate color for that utility. On unpaved surfaces spikes with
pink feathers identify the alignment or pothole locations.
Vacuum excavation entails the use of a vacuum truck as a mode of extraction coeval with high-pressure
air or water as the mode of excavation. A hole is first cored or chiseled through the pavement 8 to 12
inches in diameter through which the vacuum hose and high pressure hose is inserted. Holes in substrate
materials such as sand excavate quickly while those in cobble may require considerable time. Trenches
are excavated in a similar fashion to expose multiple or fragile utilities, or when an interruption in
service, due to damage by conventional backhoe, can not be tolerated.
With all of the above m.ethods for locating buried utilities the method for annotating that information on
the surface is the same. The facility is traced on the surface and two nails or feathers are placed an offset
distance apart. This distance is noted on the middle left side of the sheet. Its significance is two fold:
First, it approximates the alignment of the centerline of the pipeline or encasement; and second, it
defines the point of depth measurement at the midpoint between the nails or feathers. The depth
measurement is rounded to the nearest 1/2 inch with a tolerance of +/- VA inch. Surveyors can measure
the coordinates of both points to gain an approximation of the alignment and take the depth measure at
the midpoint. Where requested, convenient or appropriate depth measurements may be taken from a
remote point, hub or surface, such as a valve can lid or curb. If that is done a note will appear on the
data sheet showing the location of the hub and the distance.
Potholes may be slightly offset from the alignment of the utility below. On pavement pink paint between
nails marks the alignment of the pipe along with the depth to the top of the utility and a brief description
of the utility below.
AirX potholing methods require potable water that was acquired off site, and all vacuumed water was
disposed of off site. Water used during the course of potholing was completely contained and no water
was allowed to escape into storm drains or natural drainages. Utility locating was initially provided by
Underground Service Alert and verified as required by AirX Utility Surveyors prior to potholing.
SITE SPECIFIC DETAILS
AirX was contracted by the City of Carlsbad to perform locating and potholing services in Carlsbad,
Califomia, for certain utilities for Task Allotment 1, Project 6608 for storm drain improvements. AirX
applied for its own Traffic Control and Excavation Permits and performed said work.
The project area was on Madison Street at Grand Avenue, Roosevelt Street 75 feet northwest of Carlsbad
Village Drive and Ocean Street northwest from Pacific Avenue until it tums north. AirX was tasked to
do 14 potholes, 4 at Madison, 1 at Roosevelt and 9 on Ocean Street. Traffic control was provided by
AirX and a permit was required by the City of Carlsbad. Traffic was fairly heavy on Madison and
Roosevelt during the noon hour and after about 2:30 pm. The traffic on Ocean Street was relatively
light. The soil stratification was mostly sandy clay and the potholes were backfilled with slurry and the
pavement was resurfaced with hot asphalt. Every Wednesday the Farmers Market is set up and traffic is
very heavy at that time. The results of the work have been written on the pavement and annotated in this
report.
PROJECT AREA PHOTOGRAPHS
Above Lef^ (I): Facing northeast on Grand Avenue from the Roosevelt Street Intersection looking toward Madison. In Phase U
of this project potholes PH 101 to PH 104 where in the Madison Intersection and PH 105 was right of the photo on Roosevelt.
Above Right (2): Facing southeast on Madison Street looking across Grand Avenue along the proposed alignment of the new
storm drain. Potholes PH 101 to PH 104 ran across this intersection along the left side of the photo from near to far.
Above Left (3); Facing northwest on the southeast bound side of Roosevelt Street with Carlsbad Village Drive at the back of the
camera. The current phase pothole location is near dead center of the photo, labeled pothole PH 105.
Above Right (4): Facing southwest al the same location as in photo 3, but looking from the right in that photo. 1 his is the
building water service not marked out in the previous phase. Carlsbad Village Drive is about 75 feet to the left of the photo.
Above Left (5): Facing south-southeast on Ocean Street as it curves northeast toward Garfield Street. Note the utilities changing
from off" curb in the street to back of curb. The utilities in this area are in a common trench, pothole PH 106 through PH 114.
Above Right (6): Facing northwest on southwest side of Ocean Street looking down the utility corridor and the proposed
alignment of the storm drain. The alignment follows from the mailbox stand, left, through the white 45 degree mark out just
outside the parking lane back toward the catch basin seen in photo 5. The last pothole is seen in the center of this photo.
