IV.
Utility Locates and Excavation
All excavators shall call (811) to utilize the North Carolina One-Call Center (NCOCC) for locate
requests, marking, positive response, etc. prior to excavation and with proper request times (i.e 48hours in advance). Excavators shall exercise appropriate caution to avoid damage and ensure safety.
All excavators fall under North Carolina General Statute 87 and City of Wilmington Code Chapter 11,
Articles I and V for adherence to excavation rules and penalties. (Section 11-95).
V.
Emergency Excavations
In case of an emergency excavation, applications for permits and fees shall be made no later than 24
hours following excavation. An emergency situation is considered a sudden loss or failure of service
or an accident to a utility facility where the impacts are deemed an imminent danger to the public
health and safety. In the case of an emergency the utility facility may be accessed for necessary
repairs and site control.
VI.
Traffic Control & Public Notification
All excavations affecting motorists and pedestrians shall require a proper traffic control plan submitted
with each ROW application. The plan shall be based on the type of street(s) and the amount of traffic
using the Manual of Uniform Traffic Control Devices (MUTCD Part 6 –Temporary Traffic Control) for
guidance. Depending on the impact to traffic, businesses or residents, public notification plans (signs,
advertisements, flyers, etc) may be necessary and submitted as part of the permit. (Section 11-94).
VII.
Trench and Street Repair
Reference shall be made to City of Wilmington Technical Standards and Details for all repairs. See
SD 1-05 for street repair. Excavators shall factor soil contents and soil moisture when backfilling a
trench with the intent to avoid the creation of voids, soil bridging or settlement.

Backfill shall be suitable material that is free from heavy clay, gumbos, debris, organics and
little to no excessive moisture.
Select backfill may be substituted or required by City to achieve compaction, (i.e. #57, ABC,
crushed limestone, clean sand, flowable fill, etc).
8-inch of aggregate base course (ABC) material shall be used on City streets.
Backfill and base materials shall be compacted in 12” maximum lifts.
Soil shall be compacted by a mechanized tamper (i.e jumping jack) for most excavations,
however, vibratory rollers > 18” width may be used for larger excavations. Under no
circumstances shall the plate tamp method be used.
All approved castings shall be set flush to grade and supported if applicable.
ABC and subbase compacted to 98% and backfill and embedment compacted to 90% of the
maximum dry density as determined by the modified AASHTO Method T-99.
1-foot cutbacks of existing asphalt shall be made on undisturbed soil. Clean square cuts shall
be applied with tack to all asphalt joints.
Superpave 9.5A or B asphalt shall be installed in lifts to match the existing pavement
thickness in or 2” minimum. Minimum asphalt density is 90% of maximum specific gravity.

VIII.
Pavement Restoration
Where excavations impact the pavement, the applicant shall provide the dimensions on the permit.
Applicant shall utilize Figure1, to develop the limits of pavement restoration. All pavement restoration
cuts shall tend to be linear and perpendicular while avoiding the wheel path. Where an applicant
requires multiple cuts in a block or section of street, the City reserves the right to require full lane or
full width restoration. (Section 11-96). For instance, if 35% of the asphalt or consecutive cuts are
made within a block (typical 500’) or lane the City may require full lane or full width restoration.
Additionally, no pavement restoration shall be left less than 5’ from the edge of curb or roadway.
Where utility excavation occurs on a newly resurfaced area or a substantial road section (i.e high
volume), additional paving and/or milling may be required. Extended milling shall extend a minimum
of 10’ either side of the excavation. Milling shall be no less than 1-inch in depth. An applicant may
also be asked to extend pavement in collaboration with the City Streets department or others to assist
with efforts to maintain streets in good working condition.
IX.
Restoration for all other City Facilities
Where excavations impact other City facilities such as stormwater piping or boxes, driveways,
curbing, sidewalks, signs, traffic loops, lighting, landscaping, etc the contractor shall reference all
applicable City of Wilmington Technical Standards and Details to restore these facilities. Directional
drilling methods may be used to cross under a driveway, curb or sidewalk; however, there will be no
tunneling or jetting for this purpose. Concrete provided for restoration shall be from a drum mix.
X.
Quality Control and Inspections
The City requires strict adherence to standard details and permit requirements. Observation and
Quality Control testing may be performed and/or required for compaction efforts, densities, stone or
asphalt thickness, materials delivered, job mix formula, trucking tickets, etc. At no cost to the City,
these observation and testing efforts may be required, with any testing results submitted to the City
within 2 business days. These tests may include observation, compaction, stone densities, asphalt
cores, asphalt densities, etc. Failure to adequately meet minimal standards or test requirements shall
result in re-excavation and re-work of the trench or restoration to the satisfaction of the City.
XI.
Temporary Repair
Where construction activities require a trench to be backfilled or covered for any reason, including
restoring traffic, resuming construction, or awaiting asphalt restoration, the contractor shall safely
maintain the trench and all traffic control until the following temporary pavement repairs are made on a
suitable base in a safe manner:
Less than 24-hours
30 days >1 day (i.e. next week)
> 30 days (permanent)
– 6” compacted ABC stone
– 2” hot mix or cold patch asphalt
– 2” minimum hot mix asphalt
Steel plates may be used up to 30 days with prior approval from the City. Cold patch materials are not
considered a permanent pavement application and thus are only acceptable for a period of 30 days.
Depending on the type of street and weather conditions the City reserves the right to determine the
type of temporary asphalt repairs required at that time.

XII.
Final Asphalt and Striping Restoration
Upon completion of the utility work the contractor restore pavement and striping in a timely manner to
minimize impacts to the travelling public, typically 3-5 business days. Appropriate tack shall be used
and Superpave 9.5A or B asphalt shall be applied in lifts to match existing thickness or a minimum of
2-inches with a minimum density of 90%. Any alternate material shall first be approved by City
Engineering prior to placement. Under no circumstances shall the contractor attempt to skim patch on
top of existing asphalt.
Removed traffic markings or striping shall be restored within 3 days using original thermo-plastic or
paint materials.
XIII.
Brick Street Restoration
Excavators shall become familiar with City requirements to secure the bricks for reuse in a careful
manner and deliver to the City Operations center by contacting the Streets department. The
excavation of bricks shall generally be performed by hand with pry bar tools to avoid damage, stacked
on wooden pallets and wrapped for delivery. Typically, for the final layer, excavators install 12-inches
of compacted ABC (98% density) and then notify City of completion for subsequent installation of
bricks.
XIV.
Concrete Street Restoration
Upon completion of the trench the utility or contractor shall be allowed to pour concrete. The common
standard shall be 4000 psi concrete. Any alternate material shall be first approved by the City
Engineer prior to placement. New concrete shall be applied to the same thickness as existing
conditions or a minimum of 6-inches.
XV.
Worksite Safety and Access
Any Permittee conducting repairs, excavation or utility work shall take reasonable actions and
precautions to ensure that such work does not endanger people or property, nor interfere with the free
and proper use of public streets, alleys, sidewalks, bridges, etc. nor hinder with the operation of any
other utilities, etc. (Section 11-91).
XVI.
Warranty
All excavations and street repairs shall be guaranteed against failure for a period of 18 months after
completion of asphalt restoration. The warranty period shall start the first of the month following
th
completion. Example: a repair completed on the 20 of June shall be warranted from July 1st until
st
December 31 the following year. A failure is defined as settlement greater than 1/8 -inch in depth as
determined by the DOT straight edge method, pulled joints, cracking of the patch; etc. Upon discovery
of failures from inspections, the City may contact Applicant of such failures to make repairs as
needed. (Section 11-96).
