2.0 Acceptance of Improvements: Upon completion of the improvements, Property Owner shall
contact the Weld County Department of Public Works and request an inspection of such improvements.
Upon request, County personnel will initiate the inspection, approval, and acceptance process.
3.0 Inspection, Approval, and Acceptance Process:
3.1 Upon completion of construction of all improvements as described in the Construction
Plans, Property Owner shall submit to the Weld County Department of Public Works a Statement
of Substantial Compliance by Property Owner's Engineer along with "as -built" drawings as
required in B.3.2.3, above, and shall request County inspection of the Improvements. County
personnel shall then inspect the improvements. If the County determines the improvements were
not constructed in accordance with the Construction Plans, the County shall direct the Property
Owner to correct the deficiencies. If the County determines the improvements were constructed in
accordance with the Construction Plans, the County shall initially approve the Improvements.
3.2 Two -Year Warranty Period. Such initial approval begins the two-year warranty period.
Upon completion of the two-year warranty period, County Public Works personnel shall, upon
request by the Property Owner, inspect the subject improvements, and notify the Property Owner
of any deficiencies. If any deficiencies are discovered, the Property Owner shall correct the
deficiencies. County personnel shall re -inspect the improvements after notification from the
Property Owner that said deficiencies have been corrected. If the County personnel fmds that the
improvements are constructed according to County standards, he or she shall approve the
improvements. Such final approval shall authorize the Property Owner to request the Board of
County Commissioners to release the Warranty Collateral.
3.3 Placement of Improvements into Service Prior to County Approval. If requested by the
Property Owner and agreed by the County, portions of the improvements may be placed in service
when completed according to the schedule shown on the construction schedule exhibit, but such
use and operation shall not alone constitute an approval or acceptance of said portions of the
improvements. County may, at its option, issue building permits for construction for which the
improvements detailed herein have been started but not completed according to the schedule shown
on the construction schedule exhibit, and may continue to issue building permits so long as the
progress of work on the improvements is satisfactory to the County, and all terms of this Agreement
have been faithfully kept by Property Owner.

PROJECT DESCRIPTION AND SCOPE
Project Location
The project lies in part of the southwest quarter of Section 32, Township 6 North, Range 65 West of
the 6th P.M., City of Greeley, Weld County, Colorado. The proposed road is located to the south of
O Street and to the west of North First Street and is generally located to the northeast of Greeley,
Colorado. The proposed road will be as an access road to four industrial lots south of O Street.
Currently, the access road is paved from O Street approximately 300 feet south along the western
property line of Taylors Implement Co. The proposed road will extend approximately 800 linear
feet south of what is currently paved. The approximate location of the site is shown in the Site
Vicinity Map on Figure 1.
Project Description
The O Street Pavement project is to consist of a subsurface soils investigation and pavement design.
The purpose is to develop anticipated pavement sections for the proposed road to accommodate the
future development of a parcel of vacant, semi -developed property for industrial/commercial use.
Geotechnical recommendations for the foundations for the surrounding areas are not included in this
subsurface soils investigation or this report. The proposed road will not be a thru road and will be an
access road to four industrial zoned lots.
Scope of Work
RMG was retained to assess the soil conditions and develop geotechnical engineering
recommendations for the pavement design portion for the proposed extension of a road off the south
of O Street. Our scope of services consisted of a field investigation, laboratory testing, engineering
analysis, and report preparation.
This report presents geotechnical engineering recommendations for the construction and installation
of the pavement extension of the road. The recommendations in this report are also contingent upon
completion of an observation of the soils by RMG, prior to the placement of pavement in order to
verify subsurface conditions for the specific excavated site.
The following is excluded from the scope of this report including but not limited to geologic, natural
and environmental hazards such as landslides, unstable slopes, seismicity, snow avalanches, water
flooding, corrosive soils, erosion, radon, wild fire protection, hazardous waste and natural resources.
Existing Site Conditions
At the time of our field exploration this portion of the development had been graded in the area of
the future road as well as to the east, where it appeared commercial buildings were planned for
future construction. Curb and gutter had not been installed along the current stretch of road
previously paved. Topography of the site generally sloped gently down from northern portion to the
southern portion of the site. Vegetation was not present at the site.

FIELD INVESTIGATION AND LABORATORY TESTING
The information included in this report has been compiled from field reconnaissance, exploratory soil
borings and soil laboratory testing. Monitoring programs, which typically include instrumentation and/or
observations for surface water flows, slope stability, subsidence, and similar conditions, are not known
to exist and were not considered applicable for the scope of this report.
Subsurface Investigation
The subsurface conditions on the site were investigated by drilling 3 exploratory test borings within
the proposed future roadway. The approximate locations of the test borings are presented in the
Boring Location Plan on Figure 2.
The test borings were advanced with a truck -mounted, continuous -flight auger drill rig to depths of
about 10 feet below the existing ground surface (bgs). Soil samples were obtained from the test
borings in general accordance with ASTM D-3550 utilizing a 2%2 -inch OD modified California
sampler. Additionally, bulk samples of the worst soils encountered were obtained for further testing.
The approximate depth of groundwater was investigated in each of the test borings at the time of
drilling. The Test Boring Logs are presented in Figures 3 and 4. An Explanation of Test Boring
Logs is presented in Figure 5.
Laboratory Testing
The moisture content and dry density for the recovered samples was obtained in the laboratory.
Grain -size analysis, Atterberg Limits, and swell/consolidation tests were performed on selected
samples for purposes of classification and to develop pertinent engineering properties. Additionally,
a Resistance "R -Value" test was performed on bulk sample collected from the pavement borings. A
Summary of Laboratory Test Results is presented in Figure 6. Soil Classification and Atterberg Test
Results are presented in Figure 7. The R -Value test results are presented in Figure 8.
SUBSURFACE CONDITIONS
Soil and Bedrock Profile
The subsurface materials encountered in the test borings were classified using the Unified Soils
Classification System (USCS). The subsurface materials encountered in the test borings generally
consisted of silty to clayey sand and sandy to silty clay extending to 10 feet below existing grade.
Additional descriptions and the interpreted distribution (approximate depths) of the subsurface
materials are presented on the Test Boring Logs. The classifications shown on the logs are based
upon the engineer's classification of the samples at the depths indicated. Stratification lines shown
on the logs represent the approximate boundaries between material types and the actual transitions
may be gradual and vary with location.

Groundwater
Groundwater was not observed in any of the test borings at the time of drilling or when checked the
day following drilling. Fluctuations in groundwater and subsurface moisture conditions may occur
due to variations in rainfall and other factors not readily apparent at this time. Development of the
property and adjacent properties may also affect groundwater levels.
CONCLUSIONS
The following discussion is based on the subsurface conditions encountered in the test borings and on
the project characteristics previously described. If conditions are different from those described in this
report or the project characteristics change, RMG should be retained to review our recommendations
and adjust them, if necessary. The results of this investigation indicate that the site is suitable for the
proposed project provided the recommendations presented herein are implemented.
As previously discussed the site is underlain primarily loose clayey to silty sand and soft sandy to silty
clay extending 10 feet below existing grade.
Geotechnical recommendations based on the field investigation and laboratory testing are presented
below. It must be understood that these recommendations should be verified prior to installing the
pavement.
PAVEMENT RECOMMENDATIONS
Pavement Subgrade
Pavement performance is directly affected by the degree of compaction, uniformity, and stability of
the prepared subgrade. The stability and quality of the pavement subgrade is particularly important
where high traffic volume and/or heavy axle loads are anticipated. Non -uniform pavement support
can result from variations in soil types and consistencies, particularly at transitions between cut -and -
fill areas. Our recommendations for a well -prepared and compacted pavement subgrade are
presented in the following paragraphs.
It is difficult to place new fill and/or pavement on a soft and yielding subgrade. After completion of
ono stripping, cutting, and/or over -excavation operations, and prior to the placement of any new fill or
base course, the exposed subgrades should be proof -rolled with heavy construction equipment. The
proof -rolling process delineates shallow zones of soft soils, which may require additional
compaction or removal.
mos
ao� In areas to receive additional fill or base course, we recommend the upper 1 foot of the existing
c soft/loose subgrade soils be scarified and moisture conditioned to 0% to +2% of optimum moisture
" and compacted to 95% of the maximum dry density as determined by the Standard Proctor method
N
oc� (ASTM D-698). The soils encountered at this site classified as A-4 according to AASHTO.
as . Following Section 203 of the most recent CDOT Standards, these A-4 soils contain greater than 35%
dim s fines, these soils will require obtaining optimum moisture content. Prior to placing any new fill, the
a_ t:4! • reworked subgrade should be proof rolled. This will improve the density of near -surface soils, and
mwa develop a firm base on which new fill soils can be compacted against. Stability of the subgrade
�Nxshould be verified prior to the installation of additional fill via proof rolling. Based on the existing

soil R -Value result of 8 at an exudation pressure of 300 psi used in the pavement design, imported
structural (select) fill with the same or better R -Value should be used to construct this project.
Please note, imported fill is NOT base course.
We recommend all fill used to develop design subgrades consist of structural (select) fill, free of
organic matter and other deleterious material, in accordance with the Structural (Select) Fill section
of this report. Reworked on -site soils and import fill should be placed in 6 to 8 inch thick lifts and
compacted to a minimum of 95 percent of the material's maximum dry unit weight as determined by
the Standard Proctor procedure (ASTM D-698). The moisture content of subgrade soils containing
silt and clay should be at the soil's optimum water content and up to 2% over optimum. t the time of
compaction and should be maintained prior to final construction.
Once the subgrade material has been properly prepared and tested base course fill can be placed and
compacted in accordance with the Structural (Select) Fill section in this report.
Surface drainage around the pavement is also important to long-term performance. Curbs or slab
edges should be backfilled as soon as possible after pavement construction curing. Backfill and/or
shouldering should be compacted and sloped to prevent water from ponding and infiltrating under
the new pavement. Pavement joints and cracks observed over the life of the pavement should be
promptly sealed to prevent moisture intrusion into the subgrade.
Pavement Design
The pavement design was evaluated using Weld County Engineering and Construction Guidelines
(Standards) to estimate the anticipated Equivalent Daily Load Application (EDLA) for the future
industrial/commercial properties. From the Table 2.08.1: Flexible Pavement Design Criteria, the
minimum Equivalent Daily Load Application (EDLA) for a 2 -Lane industrial/commercial local road
is 50 which equates to 20 year design traffic Equivalent Single Axle Load (ESAL) of 365,000.
The existing subgrade soils were analyzed to determine their classification in accordance to the
USCS (ASTM D-2487) and the AASHTO (M-145). A Resistance Value (R -Value) test (ASTM D-
2844/AASHTO T-190) was conducted on the soil classified as the weakest subgrade material and
was determined to be 8 at an exudation pressure of 300 psi. A Resilient Modulus (MR) of 3,315 psi
was determined from these subgrade materials and CDOT Pavement Design Manual equations 2.1
and 2.2:
Equation 2.1: S1= [(R-5)/11.29]+3
Equation 2.2: MR = 10«si+18 X2)/6.241
Local subgrade drainage characteristics of the proposed pavement areas are considered to be fair to
good. Fair drainage characteristics were used to control the design. These characteristics, coupled
with the approximate duration of saturated subgrade conditions, results in an AASHTO design
drainage coefficient of 1.0.
For the thickness design of this proposed road, a design life of 20 years and a terminal serviceability
index of 2.5 were used in general accordance with Table 7-4. Reliability of 80% for local roads
(Table 7-4) and standard deviations of 0.44 for flexible design (Table 7-7) were also used following
criteria for local industrial/commercial roads in the Standards.
RMG — Rocky Mountain Group
6 RMG Job No. 172999
Summarized design variables for the flexible pavement design are provided in Table 1 below. The
thickness and type of asphalt and base course layers were determined in accordance with AASHTO
pavement design methodology. The recommended pavement thicknesses for flexible pavement are
provided in Table 2.
Pavement Criteria
The existing subgrade soils had an R -Value of 8.0 at an exudation pressure of 300 psi. The
AASHTO design chart nomographs for flexible pavements were used to determine the respective
structural numbers (Sn) for the proposed pavement thickness for the future street. The nomograph
method determined a structural number of 3.3. The nomographs are provided as Figure 10.

* Weld County Engineering and Construction Guidelines
Pavement Recommendations
The pavement section recommendations are based on the worst subgrade soils observed on site. The
on -site soils do not appear to be significantly different to require an additional pavement section on a
portion of the site.
The bottom 4" of HMA needs to be PG 64-22 (S)(75). The top 2" of HMA needs to be PG 64-
22(SX)(75). The HMA must be laid in lifts no greater than 4 inches.
The ABC Class 5 or Class 6 base course must have a minimum R -value of 68.

Construction Recommendations
The subgrade and any fill should be prepared in accordance to the Pavement Subgrade section of
this report. Prior to placement pavement, the subgrade and/or imported fill should meet compaction,

moisture, and stability requirements. Testing and observation of these items should be conducted by
RMG as the Geotechnical Engineer.
Drainage of surface and subsurface water is also a critical component of pavement performance.
Wetting of the subgrade soils will cause loss of support strength resulting in premature pavement
distress. Surface drainage should be designed to remove all water from paved areas. Regular active
maintenance of pavements, which includes filling of cracks and joints, is required to minimize water
infiltration and lengthen pavement life.
Structural (Select) Fill
Structural fill for this project should be in accordance with this report section. Areas to receive
structural fill should have topsoil, organic material, and construction debris removed as preparation
for structural fill placement. The upper 12 inches of the exposed surface soils should be scarified
and moisture conditioned for a loose generally even thickness layer to facilitate compaction.
Compact this subgrade soil to a minimum of 95 percent of the maximum dry density and 0% to +2%
of optimum moisture content as determined by the Standard Proctor test (ASTM D-698/AASHTO
T-99).
Structural fill materials should be approved by the RMG prior to hauling it to the site. We
recommend project structural fill consist of a granular material, having Atterberg limits values of 40
maximum for liquid limit and 20 maximum for plastic index, and have a minimum R -Value of 8.
The base course material must have a minimum R Value of 68.
Structural fill should not be placed on frozen subgrade or allowed to freeze during moisture
conditioning, placement and compaction phases of earthwork construction. Structural fill placed on
slopes should be benched into the slope. Maximum bench heights should not exceed 4 feet and
bench widths should be wide enough to accommodate compaction equipment.

Structural fill should be placed in even loose lifts not exceeding 8 to 12 inches, moisture conditioned
to facilitate compaction (within 2 percent of the optimum moisture content) and compacted to a
minimum of 95 percent of the Standard Proctor test (ASTM D-698/AASHTO T-99) maximum dry

To verify the condition of compacted subgrade, density tests should be performed during placement.
The first density tests of the prepared subgrade should be conducted as a quality check when about

INTRODUCTION
This report presents the results of our subsurface exploration and geotechnical engineering
services performed to evaluate the existing pavements and underlying subgrade for a section of
Cimarron Court near the intersection with O Street in Greeley, Colorado. The purpose of these
services is to provide information and geotechnical engineering recommendations relative to:
Subsurface soil conditions Groundwater conditions
Site preparation and earthwork Pavement design and construction
The geotechnical engineering scope of services for this project included the advancement of two
test borings to approximately 101/2 feet below existing site grades.
Maps showing the site and boring locations are shown in the Site Location and Exploration
Plan sections, respectively. The results of the laboratory testing performed on soil samples
obtained from the site during the field exploration are included on the boring logs and as separate
graphs in the Exploration Results section of this report.

GEOTECHNICAL CHARACTERIZATION
Subsurface Profile
We have developed a general characterization of the subsurface conditions based upon our
review of the subsurface exploration, laboratory data, geologic setting and our understanding of
the project. This characterization, termed GeoModel, forms the basis of our geotechnical
calculations and evaluation of site preparation and foundation options. Conditions encountered at
each exploration point are indicated on the individual logs. The individual logs can be found in the
Exploration Results section and the GeoModel can be found in the Figures section of this report.

As noted in General Comments this characterization is based upon widely spaced exploration
points across the site and variations are likely.
Groundwater Conditions
Groundwater was not observed in the remaining borings while drilling, or for the short duration the
borings could remain open. However, this does not necessarily mean the borings were terminated
above groundwater, or the water levels summarized above are stable groundwater levels. Due to
the low permeability of the soils encountered in the borings, a relatively long period may be necessary
for a groundwater level to develop and stabilize in a borehole. However, we do not believe
groundwater will impact the proposed project.
Laboratory Testing
Representative soil samples were selected for swell -consolidation testing and exhibited 0.2 and
0.3 percent swell when wetted. Samples of site soils selected for plasticity testing exhibited
moderate plasticity with liquid limits ranging from 27 to 35 and plasticity indices ranging from 16 to
23. Laboratory test results are presented in the Exploration Results section of this report.
GEOTECHNICAL OVERVIEW
Based on subsurface conditions encountered in the borings, the site appears suitable for either
overlaying the existing pavement with asphalt or completely milling the existing pavement and
placing a new section of asphalt. Site grades will likely be adjusted and drainage modifications
from the current site conditions are likely. These conditions will require particular attention in
project planning, design and during construction and are discussed in greater detail in the
following sections.

PAVEMENTS
Pavements — Subgrade Preparation
lierracon
GeoReport
Based on subsurface conditions encountered in the borings, the site appears suitable for either
overlaying the existing pavement or completely milling the existing pavement and placing a new
section of asphalt. Weld County requires extending the new pavement, whether overlaid or a
new section, to extend a minimum of 1 foot into the existing pavement (O Street), with a minimum
thickness of 2 inches. This tie-in will require milling a portion of O Street.
If a complete milling option is selected, the resulting pavement subgrade may not be suitable for
pavement construction and corrective action will be required. The subgrade should be carefully
evaluated at the time of pavement construction for signs of disturbance or instability. We
recommend the pavement subgrade be thoroughly proof rolled with a loaded tandem -axle dump
truck prior to final grading and paving. All pavement areas should be moisture conditioned and
properly compacted to the recommendations in this report immediately prior to paving.
Pavements - Design Recommendations
Design of pavements for the project have been based on the procedures outlined in the 1993
Guideline for Design of Pavement Structures prepared by the American Association of State
Highway and Transportation Officials (AASHTO) and the Weld County Engineering and
Construction Guidelines as well as the City of Greeley Design Criteria and Construction
Specifications.
A sample of the fill materials selected for swell -consolidation testing swelled approximately 0.3
percent when wetted under an applied pressure of 150 psf which is less than the maximum 2
percent criteria established for determining if swell -mitigation procedures in the pavement sections.
Therefore, swell -mitigation of the subgrade materials prior to pavement operations is not required.
Traffic patterns were documented in the traffic impact study (Kellar Engineering, report dated May
31, 2019) which estimated 198 daily trips will be generated. In addition, RMG Engineers (report
dated October 29, 2019) estimated an 18 -kip equivalent single -axle load (ESAL) of 365,000 for
the proposed development area. These assumed traffic design values should be verified by the
civil engineer or owner prior to final design and construction. If the actual traffic values vary from
the assumed values, the pavement thickness recommendations may not be applicable. Terracon
should be contacted so that the design recommendations can be reviewed and revised if
necessary.
Similar to the RMG report, a terminal serviceability index of 2.3 was utilized along with an inherent
reliability of 80 percent and a design life of 20 years. Using the correlated design R -value of 11,
appropriate ESAL, environmental criteria and other factors, the structural numbers (SN) of the

pavement sections were determined on the basis of the 1993 AASHTO design equation. For the
overlay option, a reduced asphalt layer coefficient was used to determine the overlay thickness.
In addition to the flexible pavement design analyses, a rigid pavement design analysis was
completed based upon AASHTO design procedures. Rigid pavement design is based on an
evaluation of the Modulus of Subgrade Reaction of the soils (k -value), the Modulus of Rupture of
the concrete, and other factors previously outlined. The design k -value of 100 for the subgrade
soil was determined by correlation to the laboratory test results. A modulus of rupture of 600 psi
(working stress 450 psi) was used for pavement concrete. The rigid pavement thickness for each
traffic category was determined on the basis of the AASHTO design equation.
Recommended minimum pavement sections are provided in the table below.

The overlay section of HMA will be PG 64-22(SX)(75) per Weld County and will be placed in a single lift.
CDOT recommends asphalt lift thickness range from 11/2 to 2% inches for Grading SX and 2 to 3 inches for
Grading S.
Weld County requires the minimum R value for the aggregate base course to be 68 or greater.
For newly constructed asphalt pavements, we recommend placing a bottom lift consisting of 4 inches of
PG 64-22(S)(75) and a top lift consisting of 2 inches of PG 64 (SX)(75).
Aggregate base course (if used on the site) should consist of a blend of sand and gravel which
meets strict specifications for quality and gradation. Use of materials meeting Colorado
Department of Transportation (CDOT) Class 5 or 6 specifications is recommended for aggregate
base course. Aggregate base course should be placed in conformance with the most current
CDOT Standard Specifications for Road and Bridge Construction.
Asphaltic concrete should be composed of a mixture of aggregate, filler and additives (if required)
and approved bituminous material. The asphalt concrete should conform to approved mix
designs stating the Superpave properties, optimum asphalt content, job mix formula and
recommended mixing and placing temperatures. Aggregate used in asphalt concrete should
meet particular gradations. Material meeting CDOT Grading S and SX specifications or
equivalent are recommended for asphalt concrete. Mix designs should be submitted prior to
construction to verify their adequacy. Asphalt material should be placed in maximum 3 -inch lifts

Concrete should be deposited by truck mixers or agitators and placed a maximum of 90 minutes
from the time the water is added to the mix. Longitudinal and transverse joints should be provided
as needed in concrete pavements for expansion/contraction and isolation per ACI 325. The
location and extent of joints should be based upon the final pavement geometry.
Although not required for structural support, a minimum 4 -inch thick aggregate base course layer
is recommended for the PCC pavements to help reduce the potential for slab curl, shrinkage
cracking, and subgrade "pumping" through joints. Proper joint spacing will also be required for
PCC pavements to prevent excessive slab curling and shrinkage cracking. All joints should be
sealed to prevent entry of foreign material and dowelled where necessary for load transfer.
For areas subject to concentrated and repetitive loading conditions such as dumpster pads, truck
delivery docks and ingress/egress aprons, we recommend using a portland cement concrete
pavement with a thickness of at least 6 inches underlain by at least 4 inches of granular base.
Prior to placement of the granular base, the areas should be thoroughly proof rolled. For dumpster
pads, the concrete pavement area should be large enough to support the container and tipping
axle of the refuse truck.
Pavement performance is affected by its surroundings. In addition to providing preventive
maintenance, the civil engineer should consider the following recommendations in the design and
layout of pavements:
Site grades should slope a minimum of 2 percent away from the pavements;
The subgrade and the pavement surface have a minimum 2 percent slope to promote proper
surface drainage;
Consider appropriate edge drainage and pavement under drain systems;
Install pavement drainage surrounding areas anticipated for frequent wetting;
Install joint sealant and seal cracks immediately;

GeoReport
Seal all landscaped areas in, or adjacent to pavements to reduce moisture migration to
subgrade soils; and
Placing compacted, low permeability backfill against the exterior side of curb and gutter.
Pavements - Construction Considerations
Openings in pavement, such as landscape islands, are sources for water infiltration into
surrounding pavements. Water collects in the islands and migrates into the surrounding subgrade
soils thereby degrading support of the pavement. This is especially applicable for islands with
raised concrete curbs, irrigated foliage, and low permeability near -surface soils. The civil design
for the pavements with these conditions should include features to restrict or to collect and
discharge excess water from the islands. Examples of features are edge drains connected to the
storm water collection system or other suitable outlet and impermeable barriers preventing lateral
migration of water such as a cutoff wall installed to a depth below the pavement structure.
Pavements - Maintenance
Preventative maintenance should be planned and provided for an ongoing pavement
management program in order to enhance future pavement performance. Preventive
maintenance consists of both localized maintenance (e.g. crack and joint sealing and patching)
and global maintenance (e.g. surface sealing). Preventative maintenance is usually the first
priority when implementing a planned pavement maintenance program and provides the highest
return on investment for pavements.
EARTHWORK
The following presents recommendations for site preparation, excavation, subgrade preparation,
fill materials, compaction requirements, utility trench backfill, and grading and drainage.
Earthwork on the project should be observed and evaluated by Terracon. Evaluation of earthwork
should include observation and/or testing of over -excavation, removal of existing asphalt section
(if selected), subgrade preparation, placement of engineered fills, subgrade stabilization and other
geotechnical conditions exposed during the construction of the project.
Site Preparation
If the complete repaving option is selected, completely remove the existing pavement and
underlying base course to native subgrade. Existing vegetation, topsoil, and any other deleterious
materials present in the existing shoulders, should also be removed from the proposed construction
areas
Prior to the placement of fills, the site should be graded to create a relatively level surface to receive
fill, and to provide for a relatively uniform thickness of fill beneath proposed structures.

Excavation
lierracon
GeoReport
It is anticipated that excavations for the proposed construction can be accomplished with
conventional earthmoving equipment.
The soils and pavements to be excavated can vary significantly across the site as their
classifications and measurements are based solely on the materials encountered in widely -spaced
exploratory test borings. The contractor should verify that similar conditions exist throughout the
proposed area of excavation. If different subsurface conditions are encountered at the time of
construction, the actual conditions should be evaluated to determine any excavation modifications
necessary to maintain safe conditions.
If unexpected underground facilities are encountered, such features should be removed and the
excavation thoroughly cleaned prior to backfill placement and/or construction.
The subgrade soil conditions should be evaluated during the excavation process and the stability
of the soils determined at that time by the contractors' Competent Person. Slope inclinations flatter
than the OSHA maximum values may have to be used. The individual contractor(s) should be
made responsible for designing and constructing stable, temporary excavations as required to
maintain stability of both the excavation sides and bottom. All excavations should be sloped or
shored in the interest of safety following local, and federal regulations, including current OSHA
excavation and trench safety standards.
As a safety measure, it is recommended that all vehicles and soil piles be kept a minimum lateral
distance from the crest of the slope equal to the slope height. The exposed slope face should be
protected against the elements
Subgrade Preparation
Weld County requires subgrade preparation to be completed in accordance with the most current
CDOT Standard Specifications for Road and Bridge Constructions.
After the bottom of the excavation has been compacted, engineered fill can be placed to bring the
pavement subgrade to the desired grade. Engineered fill should be placed in accordance with
the recommendations presented in subsequent sections of this report.
The stability of the subgrade may be affected by precipitation, repetitive construction traffic or
other factors. If unstable conditions develop, workability may be improved by scarifying and
drying. Alternatively, over -excavation of wet zones and replacement with granular materials may
be used, or crushed gravel and/or rock can be tracked or "crowded" into the unstable surface soil
until a stable working surface is attained.

Description
Per Section 203 of the Colorado Department of
Transportation (CDOT) Standard Specifications for Road
and Bridge Construction
We recommend engineered fill be tested for moisture content and compaction during placement. Should the
results of the in -place density tests indicate the specified moisture or compaction limits have not been met,
the area represented by the test should be reworked and retested as required until the specified moisture
and compaction requirements are achieved.
Specifically, moisture levels should be maintained low enough to allow for satisfactory compaction to be
achieved without the fill material pumping when proof rolled.
Moisture conditioned clay materials should not be allowed to dry out. A loss of moisture within these materials
could result in an increase in the material's expansive potential. Subsequent wetting of these materials could
result in undesirable movement.
Utility Trench Backfill
All trench excavations should be made with sufficient working space to permit construction including
backfill placement and compaction.
All underground piping within or near the proposed improvement should be designed with flexible
couplings, so minor deviations in alignment do not result in breakage or distress. Utility knockouts
should be oversized to accommodate differential movements. It is imperative that utility trenches be
properly backfilled with relatively clean materials. If utility trenches are backfilled with relatively
clean granular material, they should be capped with at least 18 inches of cohesive fill in non -
pavement areas to reduce the infiltration and conveyance of surface water through the trench
backfill.
It is strongly recommended that a representative of Terracon provide full-time observation and
compaction testing of trench backfill within pavement areas.
Grading and Drainage
Pavement performance is affected by its surroundings. In addition to providing preventive
maintenance, the civil engineer should consider the following recommendations in the design and
layout of pavements:
Site grades should slope a minimum of 2 percent away from the pavements;
The subgrade and the pavement surface have a minimum 2 percent slope to promote proper
surface drainage;
Consider appropriate edge drainage and pavement under drain systems;
Install pavement drainage surrounding areas anticipated for frequent wetting;
Install joint sealant and seal cracks immediately;
Seal all landscaped areas in, or adjacent to pavements to reduce moisture migration to
subgrade soils; and
Placing compacted, low permeability backfill against the exterior side of curb and gutter.

Construction Observation and Testing
lierracon
GeoReport
The earthwork efforts should be monitored under the direction of Terracon. Monitoring should
include documentation of adequate removal of vegetation and topsoil, proof rolling, and mitigation
of areas delineated by the proof roll to require mitigation. Each lift of compacted fill should be
tested, evaluated, and reworked as necessary until approved by Terracon prior to placement of
additional lifts.
In areas of excavations, the bearing subgrade should be evaluated under the direction of
Terracon. In the event that unanticipated conditions are encountered, Terracon should prescribe
mitigation options.
In addition to the documentation of the essential parameters necessary for construction, the
continuation of Terracon into the construction phase of the project provides the continuity to
maintain Terracon's evaluation of subsurface conditions, including assessing variations and
associated design changes.
GENERAL COMMENTS
Our analysis and opinions are based upon our understanding of the project, the geotechnical
conditions in the area, and the data obtained from our site exploration. Natural variations will occur
between exploration point locations or due to the modifying effects of construction or weather.
The nature and extent of such variations may not become evident until during or after construction.
Terracon should be retained as the Geotechnical Engineer, where noted in this report, to provide
observation and testing services during pertinent construction phases. If variations appear, we

own risk. No warranties, either express or implied, are intended or made.
Site characteristics as provided are for design purposes and not to estimate excavation cost. Any
use of our report in that regard is done at the sole risk of the excavating cost estimator as there
may be variations on the site that are not apparent in the data that could significantly impact
excavation cost. Any parties charged with estimating excavation costs should seek their own site
characterization for specific purposes to obtain the specific level of detail necessary for costing.
Site safety, and cost estimating including, excavation support, and dewatering
requirements/design are the responsibility of others. If changes in the nature, design, or location
of the project are planned, our conclusions and recommendations shall not be considered valid
unless we review the changes and either verify or modify our conclusions in writing.

EXPLORATION AND TESTING PROCEDURES
Field Exploration
The field exploration program consisted of the following:
Number of Borings
2
Boring Depth (feet)
lierracon
GeoReport
Location
10 Existing pavement areas
Boring Layout and Elevations: We used handheld GPS equipment to locate borings with an
estimated horizontal accuracy of +/-20 feet. A ground surface elevation of 500.0 feet was assigned
to the top of the existing asphalt surface.
Subsurface Exploration Procedures: We advanced soil borings with a truck -mounted drill rig
using continuous -flight, solid -stem augers. Three samples were obtained in the upper 10 feet of
each boring and at intervals of 5 feet thereafter. Soil sampling will be performed using modified
California barrel, or standard split -barrel sampling procedures. For the standard split -barrel
sampling procedure, a standard 2 -inch outer diameter split -barrel sampling spoon is driven into
the ground by a 140 -pound automatic hammer falling a distance of 30 inches. The number of
blows required to advance the sampling spoon the last 12 inches of a normal 18 -inch penetration
is recorded as the Standard Penetration Test (SPT) resistance value. The SPT resistance values,
also referred to as N -values, are indicated on the boring logs at the test depths. For the modified
California barrel sampling procedure, a 2116 -inch outer diameter split -barrel sampling spoon is
used for sampling. Modified California barrel sampling procedures are similar to standard split -
barrel sampling procedures; however, blow counts are typically recorded for 6 -inch intervals for a
total of 12 inches of penetration. The samples were placed in appropriate containers, taken to our
soil laboratory for testing, and classified by a geotechnical engineer.
In addition, we observed and recorded groundwater levels during drilling observations.
Our exploration team prepared field boring logs as part of standard drilling operations including
sampling depths, penetration distances, and other relevant sampling information. Field logs
included visual classifications of materials encountered during drilling, and our interpretation of
subsurface conditions between samples. Final boring logs, prepared from field logs, represent
the geotechnical engineer's interpretation, and include modifications based on observations and
laboratory test results.
Property Disturbance: We backfilled borings with sand and pea gravel, and capped with non -
shrink grout after completion. Our services did not include repair of the site beyond backfilling our
boreholes, and patching existing pavements/surfaces. Excess auger cuttings were dispersed in
the general vicinity of the boreholes. Because backfill material often settles below the surface

after a period, we recommend checking boreholes periodically and backfilling, if necessary. We
can provide this service for additional fees, at your request.
Laboratory Testing
The project engineer reviewed field data and assigned various laboratory tests to better
understand the engineering properties of various soil strata. Laboratory testing was conducted in
general accordance with applicable or other locally recognized standards. Procedural standards
noted in this report are for reference to methodology in general. In some cases, variations to
methods are applied as a result of local practice or professional judgement. Testing was
performed under the direction of a geotechnical engineer and included the following:
Visual classification
Dry density
Grain -size analysis
R -value
Moisture content
Atterberg rg limits
One-dimensional swell
Our laboratory testing program includes examination of soil samples by an engineer. Based on
the material's texture and plasticity, we described and classified soil samples in accordance with
the Unified Soil Classification System (USCS). Soil and bedrock samples obtained during our
field work will be disposed of after laboratory testing is complete unless a specific request is made
to temporarily store the samples for a longer period of time.

DESCRIPTIVE SOIL CLASSIFICATION
Soil classification as noted on the soil boring logs is based Unified Soil Classification System. Where sufficient laboratory data
exist to classify the soils consistent with ASTM D2487 "Classification of Soils for Engineering Purposes" this procedure is used.
ASTM D2488 "Description and Identification of Soils (Visual -Manual Procedure)" is also used to classify the soils, particularly
where insufficient laboratory data exist to classify the soils in accordance with ASTM D2487. In addition to USCS classification,
coarse grained soils are classified on the basis of their in -place relative density, and fine-grained soils are classified on the basis
of their consistency. See ' Strength Terms" table below for details. The ASTM standards noted above are for reference to
methodology in general. In some cases, variations to methods are applied as a result of local practice or professional judgment.
LOCATION AND ELEVATION NOTES
Exploration point locations as shown on the Exploration Plan and as noted on the soil boring logs in the form of Latitude and
Longitude are approximate. See Exploration and Testing Procedures in the report for the methods used to locate the
exploration points for this project. Surface elevation data annotated with +/- indicates that no actual topographical survey was
conducted to confirm the surface elevation. Instead, the surface elevation was approximately determined from topographic
maps of the area.
