Larimer County Offices, Courts, District Attorney, Landfill, Household Hazardous Waste, and Recycle Center are all closed on Thanksgiving Day, November 26, 2015.
County Offices are also closed on Friday, November 27 while the Courts, District Attorney, Landfill, Household Hazardous Waste, and Recycle Center are open. Critical services at Larimer County will not be disrupted by this closure.
The purposes of these Guidelines are to:
All contractors and public utility agencies
must obtain a Right-of-Way Permit for any work performed within
the public rights-of-way of the Larimer County entities listed
below. The storage of materials and equipment within the public
rights-of-way also requires a Permit.
To preserve the original investment of the
street and roadway systems within Larimer County, minimize the
disruption and maximize the safety to the traveling public caused
by construction, and reduce future maintenance problems, it is
the policy of the Local Entities within Larimer County to require
the installation of new utilities across existing streets be done
by boring or tunneling. Open cutting of existing streets for
the installation of new utilities will be permitted only when
it can be proven it is not possible to use boring or tunneling
Applicants for Right-of-Way Permits must plan
for adequate time for review and approval by the affected Local
Entity and any other involved agencies. Generally, the greater
the scope of work, the longer the permit review and approval process

license and insurance certificates.
Once the permit form and all required submittals
have been reviewed and found to be complete, the Permit may be
approved by the Local Entity.
The approved Permit is issued to the Applicant.
Any modifications to the approved permit including any schedule
or scope changes must be submitted in writing to the Local Entity
for their review and approval. The Applicant is solely responsible
for all work for a period of two (2) years following the project
Permit Applicants are responsible for obtaining
separate permits or permission as may be required. Examples may
be when work is proposed within state highway, railroad or irrigation
company right-of-ways, or private property.
The following general conditions apply to all work done within the public rights-of-way such as utility line installation or repairs performed by any contractor or utility department, public or private.
When the final surface is not immediately installed,
it shall be necessary to place a temporary asphalt surface on
any street cut opening. The temporary surface installation and
maintenance shall be the responsibility of the Permittee until
the permanent surface is completed and accepted. It shall be
either a hot mix or cold mix paving material. Temporary surfaces
shall be compacted, rolled smooth and sealed to prevent degradation
of the repair and existing structures during the temporary period.
Permanent patching shall occur within two (2) weeks except as
outlined by the Local Entity in the Permit.
All permanent pavement patches and repairs
shall be made with "in kind" materials. For example,
concrete patches in concrete surfaces, full depth asphalt patches
with full depth asphalt, concrete pavement with asphalt overlay
patches will be expected in permanent "overlaid" concrete
streets, etc. In no case is there to be an asphalt patch in concrete
streets or concrete patch in asphalt streets. Any repair not
meeting these requirements will be removed and replaced by the
Contractor at his expense. Refer to Section 4 for details.
All work shall be done in an expedient manner.
Repairs shall be made as rapidly as is consistent with high quality
workmanship and materials. Use of fast setting concrete and similar
techniques are encouraged whenever possible without sacrificing
the quality of repair. Completion of the work including replacement
of pavement and cleanup shall normally be accomplished within
two (2) weeks after the repair work or activity involving the
cut is done. Extension of time for completion shall be with the
written approval of the Engineer. If the repairs are not completed
in the allotted time, the Local Entity has the right to repair
the street at the Contractor's expense.
Removal and replacement of unsatisfactory work
shall be completed within fifteen (15) days of written notification
of the deficiency unless deemed an emergency requiring immediate
action. In the event the replacement work has not been completed,
the Local Entity will take action upon the Contractor's bond to
cover all related costs.
The Contractor's blasting procedures shall
conform to Federal, State, and local ordinances. The Contractor
shall acquire all required permits prior to the start of blasting.
Blasting for excavation will be permitted only
after securing the approval of the Engineer. The Engineer will
fix the hours of blasting. The Contractor shall use the utmost
care to protect life and property. All explosives shall be safely
and securely stored in compliance with local laws and ordinances,
and all storage places shall be clearly marker "Dangerous
Explosives". No explosives shall be left unprotected where
they could endanger life or property
When blasting in trenches, the Contractor shall
cover the area to be shot with earth backfill or approved blasting
mats. Prior to blasting, the Contractor shall station flaggers
and provide signals of danger in suitable places to warn people
and stop vehicles. The Contractor shall be responsible for all
damage to property and injury to persons resulting from blasting
or accidental explosions that may occur in connection with the
use of explosives.
Where ground water is encountered in the excavation,
it shall be removed to avoid interfering with the work. It is
the Contractor's responsibility to comply with all Federal, State
and local permitting requirements prior to beginning any dewatering
Bituminous pavement shall be saw cut to clean,
straight lines and should be perpendicular or parallel to the
flow of traffic. (See Section 4(B)(2)(a))
In existing pavement, all excavations within
36" of the edge of the asphalt shall require removal and
replacement from the edge of asphalt to the excavation edge.
Concrete pavement, cross pans, driveways, streets
and alleys shall be removed to neatly sawed edges cut to full
When trenches are excavated in streets or alleys
which have only a gravel surface, the Contractor shall replace
such surfacing on a satisfactory compacted backfill with gravel
conforming to CDOT Class 5 or Class 6 aggregate base course.
Gravel replacement shall be one (1) inch greater in depth to that
which originally existed, but not less than four (4) inches.
The surface shall conform to the original street grade. Where
the completed surface settles, additional gravel base shall be
placed and compacted by the Contractor immediately after being
notified by the Local Entity, to restore the roadbed surface to
Some streets may have been treated with a special
surface treatment to control dust and/or bind the aggregates together.
In these cases the Contractor is responsible for installing the
gravel surface in the same manner as what was existing. Such
surface treatments shall be of the same chemical composition as
what existed prior to the excavation work. The Engineer shall
note on the permit the surface treatment that will be required.
Concrete shall be removed to neatly sawed edges
to full depth for sidewalks and curb and gutter and shall be saw
cut in straight lines either parallel to the curb or perpendicular
to the alignment of the sidewalk or curb. Any removal shall be
done to the nearest joint. Replaced sections may require doweling
connections if required by the Engineer.
FLOWABLE-FILL WILL BE REQUIRED AS UTILITY TRENCH
BACKFILL FOR ALL TRENCHES UNLESS OTHERWISE APPROVED BY THE ENGINEER.
Refer to Section 5 for compaction requirements. This requirement
applies to all pavement and gravel locations. Flowable-fill vibration
may be required.
The recommended mix for flowable-fill is shown
below. Concrete backfill will not be allowed within the
public right-of-way. Flash-fill may be used if approved by the
Engineer. Refer to CDOT specification 206.02.
|Cement||42 (0.47 sack)|
|Water||235 (39 gallons or as needed)|
|Coarse Aggregate (Size No. 57)||1700|
|Sand (ASTM C-33)||1845|
The maximum desired 28-day strength is 60 psi.
The above combination of material, or an equivalent, may be used
to obtain the desired "flowable-fill".
Flowable-fill or flash-fill shall be prohibited
as a temporary or permanent street surface. Trenches shall initially
be backfilled to the level of the original surface. After the
flowable-fill has cured, the top surface of the flowable-fill
shall be removed and the temporary or permanent surface shall
Bridging and cutback requirements as described
in these standards may still be required if the
street failures indicate a clear need.
Repair of failed trenches will be the responsibility of the party requiring the trench.
When "non flowable-fill" backfill
material has been pre-approved by the Engineer, backfill in existing
or proposed streets, curbs, gutters, sidewalks and alleys is divided
into three (3) categories: initial, intermediate and final lifts
as defined below:
Excavated material may be used in the intermediate
layer provided that it is deemed suitable by the Engineer.
Maximum dry density of all soil types used
will be determined in accordance with AASHTO T 99 or AASHTO T
180. These densities will be determined prior to placement of
When a hydro-hammer or drop hammer compaction
machine is used for compaction of fill in trenches, the maximum
layer shall be 30 inches.
See "Testing" section.
The subgrade for the pavement structure shall
be graded to conform to the cross sections and profile required
by the construction plans. Prior to the placement of aggregate
base course or sub-course, the subgrade should be properly prepared.
The subgrade should be scarified to a minimum depth of six (6)
inches, moisture adjusted as necessary, and recompacted to not
less than the following:
Prior to approval to place the base or sub-base course, all utility main and service trenches shall be compacted to not less than the above referenced densities required for the given soil classification. This density requirement also applies to all utility trenches within the public rights-of-way from a point four (4) feet beyond the edge of asphalt and descending at 1:1 outward.
Any damage, even superficial, to the existing
asphalt surface in the vicinity of the work shall be repaired
at the expense of the Contractor, including but not limited to
gouges, scrapes, outrigger marks, backhoe bucket marks, etc.
A slurry seal type covering will be considered the minimum repair.
Patching may be required, at the discretion of the Local Entity.
All street cuts shall be patched as per the
guidelines of Section 4 below.
In streets that are less then five (5) years
old the Local Entity reserves the right to deny any street excavation
or require repairs that are over and above these specifications.
- There may be situations where the patching standards are considered
inappropriate. For example, rebuilding half of a road today when
we know the road is due for reconstruction at a different profile
in 2-3 years. In these cases, the Permit Holder can provide a
more modest patch adequate to accommodate traffic for the 2-3
year period. In addition, the Permit Holder may be required to
make a financial contribution to the street maintenance, rehabilitation
or reconstruction program to support the more permanent improvements
that are anticipated. This determination shall be made by the
- Mutual acceptance of these guidelines is expected to evolve
over time with experience in the field. Disagreements over requirements
and cost sharing are inevitable. In cases where agreement cannot
be reached, the dispute shall not deter the Contractor from compliance
to the specific Permit or guidelines provided by this document
unless approved by the Engineer.
The concrete pavement shall be replaced with
4,000 psi concrete to match the finish and thickness of the existing
pavement, but not less than eight (8) inches thick. All concrete
construction shall be protected from vehicular traffic, including
contractor vehicles, until the concrete has achieved eighty (80)
percent of its ultimate strength. Concrete shall be coated and
sealed with a uniform application of membrane curing compound
applied in accordance with manufacturer's recommendations.
The use of quick curing concrete (3000 psi
strength within 48 hours) shall be used on all arterial and collector
streets when repair areas are less than 500 square feet or when
temperatures are below 40° F. Quick curing concrete repairs
may be opened to traffic within two (2) days or when the concrete
has achieved eighty (80) percent of its ultimate strength.
Where existing cracks or damage are adjacent
to the area being repaired the repair area shall include the cracked
or damaged concrete. Pavement repairs shall include all areas
of damage, including leak test holes, pot holes, equipment and/or
material scaring of the exiting surface.
When repairing concrete, removal perimeter
shall be sawcut and replacement concrete shall be doweled into
the old concrete as directed by the Engineer.
Following placement of the asphalt surface,
the joints where the new asphalt abuts the old shall be sealed
with a fog or painted coat of bitumen cement.
Joints shall be thoroughly cleaned of all foreign
material then filled with a hot-poured elastic type joint filler
conforming to M 173, ASTM D1190-80 or ASTM D1751-83, D1752-84,
D3405-78, D3406-78, D3407-78 or silicone sealants or others as
approved by the Engineer. Joint material shall be filled to within
1/2 inch of the surface. Excess material shall be scraped off
to provide a smooth riding surface.
Every street and street repair situation is unique. Design criteria and construction standards cannot address every situation but, in order to maintain some form of consistency, these standards have been developed. In most cases, they provide the minimum acceptable standards for construction or repair. Consequently, when strictly applied, they will provide the minimum acceptable product. Therefore, this criteria has been developed to maintain the same integrity of the street pavement and subsurface condition prior to its being cut for utility installations.
To achieve the goal of "Quality"
or "Excellence" in street repairs, then these criteria
shall be viewed as guidelines when used in conjunction with good
planning and judgment. This will restore the street to an acceptable
condition with minimal patching failures. In most cases, it will
be necessary to exceed the minimum standards to achieve a quality
Issues that shall be considered in a quality
approach to street repairs are as follows (these criteria must
all be balanced against the long-term maintenance needs of the
Does the final appearance of the street suggest the repairs were planned, or that they happened by accident?
Are the transitions on and off of the repair
smooth? Does the patch itself offer a smooth ride? Are the joints
located outside of the normal wheel path?
Is the repair consistent with the long-term
pavement management strategy for the particular street?
For example, suppose the repair of a utility line requires an overlay on half of a street, and that the condition of the remaining half of the street might also warrant an overlay. We may decide at that point to overlay the entire street, with Local Entity's street authority and the utility splitting the cost of the overlay. In such a case, the utility may be able to save the cost of grinding half the street. The Local Entity's street authority will allocate a reasonable percentage of their annual overlay program to accommodate their share of these situations. This includes minor (2-3 block) maintenance projects and larger capital improvement projects (major water line extension). Coordination for these types of cooperative repairs should occur as far in advance of actual construction as possible.
b. Do not allow the edges of patches to fall
in existing wheel paths. The edges of patches parallel to the
direction of traffic shall be limited to the boundaries of lanes
or to the centerline of travel lanes.
c. Patches should have a smooth longitudinal
grade consistent with the existing roadway. Patches should also
have a cross slope or cross section consistent with the design
of the existing roadway.
Will the repair pose any future maintenance
problems or make future maintenance more difficult?
The contractor is required to provide material
testing for each phase of the work and at no cost to the Local
Entity. The Independent Geotechnical Testing Firm chosen to perform
this work for the Contractor must be qualified and identified
on the Permit application.
All construction work within the public rights-of-way
shall be subject to inspection by the Engineer and certain types
of work may have continuous inspection. It shall be the responsibility
of the Contractor to provide safe access for the inspector to
perform the required inspections.
It shall be the responsibility of the person
performing the work authorized by the Permit to notify the Engineer
or his authorized representatives that such work is ready for
inspection. The Engineer requires that every request for inspection
is to be received at least twenty-four (24) hours before such
inspection is desired. Such requests may be in writing or by
telephoning or faxing the Engineer.
The Engineer may make or require other inspections
of any work as deemed necessary to ascertain compliance with the
provisions of these Guidelines or the Local Entity's Street
Design and Construction Standards, or Municipal Code. Any
work performed without the required inspections shall be subject
to removal and replacement at the Contractor's expense, regardless
of the quality of the work.
Where large scale projects exceed the ability of the Local Entity to provide inspection, the contractor or utility company will incur the cost of a private inspection firm. This inspection firm will be mutually agreed upon by the Permit applicant and the Local Entity prior to issuance of the Permit.
