ITEM TITLE: RESOLUTION OF THE CITY COUNCIL OF THE CITY OF CHULA
VISTA ADOPTING A UTILITY TRENCH MORATORNM POLICY
SUBMITTED BY: DIRECTOR OF PUBLIC WORKS
ASSISTANT DIRECTO OF ENGINEER
REVIEWED BY: CITY MANAGER

4/STHS VOTE: YES ^ NO
SUMMARY
Utility trench cuts affect the appearance of City streets and reduce the life of the pavement.
Although the City has adopted construction standazds to reduce the impact of utility trenching on
City streets, these standards do not set more stringent criteria to streets that have been recently
constructed, sealcoated, overlaid, or reconstructed. Staff recommends adoption of a utility
trenching moratorium requiring more stringent repair and resurfacing than existing City
Construction Standards for streets that have been sealcoated within the previous year and have
been constructed, overlaid, or reconstructed within the previous three years.
ENVIRONMENTAL REVIEW
The Director of Development Services has reviewed the proposed activity for compliance with
the California Environmental Quality Act (CEQA) and has determined that there is no possibility
that the activity may have a significant effect on the environment. Therefore, pursuant to Section
15061 (b)(3) of the State CEQA Guidelines the proposed action consisting of adoption of a
Utility Trench Moratorium policy is not subject to CEQA. Thus, no environmental review is
necessary.
RECOMMENDATION
Council adopt the resolution.
BOARDS/COMMISSION RECOMMENDATION
Not applicable.
DISCUSSION
Several studies have shown that utility trench cuts can reduce the service life of pavement in a
public street by as much as 50 percent. Trench cuts affect not only the pavement itself, but also
loosen the underlying base and soil, thereby causing sags and cracks over, and in the vicinity of,
the utility trench, even when repairs aze performed to City and other accepted standazds.

Recognizing the need to control excavations in public streets, Council adopted Chapter 12.16 of
the Chula Vista Municipal Code (Attachment 1), last modified in 1969 by Ordinance No. 1205.
This chapter requires parties excavating within public paved areas to repave the area in
accordance with standard specifications and to assure that the street; alley and/or sidewalk is
restored to the same condition it was in prior to the excavation. The party repaving the
excavation is required to correct any settlement that has occurred within 30 days. If the Director
of Public Works determines that it is necessary, a sealcoat can also be required to be placed
within two years after repaving is completed.
Since the effect of a utility trench extends beyond the trench itself, most cities have adopted a
"T-trench" repair for utility excavation, which extends the replacement of aggregate base and
pavement beyond the actual trench itself. The Public Works Department has adopted this type of
design in its Trench Backfill and Surface Restoration Construction Standards, CVCS-3 and
CVCS-4 (Attachment 2).
One issue that is not adequately addressed is the impact that utility trenching has on streets that
have been newly constructed or rehabilitated. The main purpose of pavement rehabilitation and
maintenance is to extend the life of an existing pavement. It is estimated that an overlay can
extend the life of pavement by as much as 20 years. If utility trenching reduces pavement life by
up to 50 percent, this is a significant reduction in the effectiveness of the City's investment.
One way that City staff attempts to reduce the effect of trenching on newly resurfaced streets is
through discussions at the Utility Coordination Committee, which is held monthly at the Public
Services Building. City staff and representatives of the utility companies attend and discuss their
upcoming projects, including pavement rehabilitation programs and planned utility upgrades.
Through these discussions, the City strives to schedule pavement rehabilitation after scheduled
work by the utility companies; in many cases, the utility companies accelerate their planned
work in order to reduce impacts to the City's constructionschedules.
However, the City also recognizes that there is emergency and unplanned work that must be
done on utilities. City staff has researched several utilities trenching policies throughout
California and the United States. Most of these policies establish a moratorium period, during
which additional work over and above the standard repair methods must be used. The minimum
period established under the proposed moratorium policy is one year for sealcoats and three
years for overlays, reconstruction and new streets. Over the past few years, City staff has been
informally requiring that utility companies comply with these requirements. However, it is
recommended that the City formally adopt such a policy (Attachment 3). This policy will not
supercede other existing rules and regulations regarding utility trenching and pavement repairs.
During the past few years, the City's Pavement Asset Management Committee has been
monitoring the policies of other agencies, particularly in the San Diego area. If other agencies
should adopt more stringent requirements, such as a longer moratorium periods, the Cornrnittee
will reevaluate the policy and propose amendments, if necessary.

DECISION MAKER CONFLICT
Staff has reviewed the decision contemplated by this action and has determined that it is not site
specific and consequently the 500 foot rule found in California Code of Regulations Section
18704.2(a)(1) is not applicable to this decision.
CURRENT YEAR FISCAL IMPACT
This action will have no direct fiscal impact.
ONGOING FISCAL IMPACT
This action will have no direct fiscal impact. However, it may have an indirect positive fiscal
impact in that it will lengthen the life of the City's pavement, thereby decreasing the cost of
pavement maintenance and rehabilitation.

BACKGROUND
Utility trenching in existing streets reduces the life of pavement. In order to reduce the impact of
utility trenching, the City has adopted construction standards (CVCS 3 & 4), which were last amended
in January 2004. Chapter 12.16 of the Municipal Code also allows the Director of Public Works to
require the person repaving the excavation to apply a seal coat at any time within two years of the time
of repaving. City staff has informally required utility companies that excavate in recently repaved
streets to meet higher standazds in order to protect the City's street ixivestment.
PURPOSE
The purpose of this policy is to protect the integrity of City streets by implementing a trench cut
moratorium to limit developers, utility companies, and City crews from digging trenches in newly
paved or sealed streets, except under emergency circumstances.
Public interest in the integrity, ride-ability and appeazance of new street surfaces is significant.
Citizens do not appreciate utility trench cuts conducted on newly resurfaced streets, and such trench
cuts reduce the pavement life. However, in the event of an emergency or new development, it will
occasionally be necessary to cut into a street that has been recently paved or repaved. The following
formalizes the City's moratorium and establishes requirements for repairing trenches in newly paved
and sealed public streets.

2. Trench Repair Requirements for Streets under Moratorium
The following trench repair requirements aze in addition to those listed in CVCS 3 & 4:
• Lateral trenches (perpendicular to the curb) -Extend T-cut grind and overlay limits to
3 feet beyond each side of the trench.
• Longitudinal trenches (parallel to the curb) -Grind 1-1/2 inches minimum and place
1-1/2 inches minimum overlay over the entire lane that is impacted (regardless of the
classification of the street).

RESOLUTION OF THE CITY COUNCIL OF THE CITY OF
CHULA VISTA ADOPTING THE UTILITY TRENCH
MORATORIUM POLICY
WHEREAS, utility trenches affect the appearance of City streets and reduce the life of
the pavement; and
WHEREAS, in order to control the type and method of trenching for utilities, the City
previously adopted Ordinance No. 1205, requiring that the street be restored to the condition it
was in prior to the excavation. The City has also adopted Trench Backfill and Construction
Standards, in order to extend the repair of pavement and base beyond the actual trench itself; and
WHEREAS, additional regulation is needed to address the impact that utility trench have
on streets that have been recently constructed or rehabilitated in order to protect the City's
investment; and
WHEREAS, the minimum moratorium period customarily required for trenching is one
year for seal coats and three years for overlays, reconstruction and new streets. Trenching that is
done during the moratorium period is required to meet more stringent requirements, as addressed
in the proposed Utility Trench Moratorium Policy (Exhibit A); and
WHEREAS, the City has informally been requiring local utilities to comply with these
policies. However, a formal Council policy is needed in order to provide specific guidelines that
can be enforced.
NOW THEREFORE, BE IT RESOLVED that the City Council of the City q~Chula
Vista adopts the Utility Trench Moratorium Policy. ,,~ ~~~~
