STA 10+43 and continuing east to STA 24+85, east of College Avenue and west of Lemay Avenue, near the
proposed Fossil Creek Bridge in Fort Collins, Colorado. This study was performed in general accordance
with our Proposal No. C2000297 (Revision No. 1) dated October 11, 2000, as well as the City of Fort Collins
Pavement Design Criteria.
Terracon prepared a geotechnical engineering pavement report containing subsurface field and laboratory
data for the site on November 24, 2000. That report was submitted to the City of Fort Collins' Engineering
Department and was based on the field and laboratory test results from test borings drilled at the site on
November 17, 2000.
We have prepared a final pavement design based on traffic data provided by the City of Fort Collins. The
results of our pavement design including design criteria and the pavement recommendations are attached.
We appreciate the opportunity to be of service to you on this phase of your project. If you have any
questions concerning this report, or if we may be of further service to you, please feel free to contact us at

FORT COLLINS, COLORADO
TERRACON PROJECT NO. 20005237
NOVEMBER 29, 2000
INTRODUCTION
This report contains the results of our pavement design for the proposed Fossil Creek Parkway
extension beginning at STA 10+43 and continuing east to STA 24+85, east of College Avenue and west
of Lemay Avenue, near the proposed Fossil Creek Bridge in Fort Collins, Colorado. The site is located in
the North 1/2 of Section 12, Township 6 North, Range 69 West of the 6th Principal Meridian.
The purpose of these services is to provide pavement sections for the proposed street improvements
within this portion of the proposed development.
The conclusions and recommendations contained in this report are based upon the results of field
and laboratory testing, engineering analyses, our experience with similar soil conditions and our
understanding of the proposed project. A geotechnical engineering pavement report was prepared
for the site by Terracon on November 24, 2000, and was based on test borings drilled at the site on
November 17, 2000, after roadway utilities were installed and subgrade was completed to near final
grades.
PROPOSED CONSTRUCTION
The proposed Fossil Creek Parkway roadway extension is to be constructed east of College
Avenue at STA 10+43 and continue east toward Lemay Avenue to STA 24+85. The roadway will
cross over the proposed Fossil Creek Bridge and is considered to be a major collector serving the
Fossil Creek Meadows 1s' Filing and the Huntington Hills 71h Filing residential developments to the
north and future projects to the south.
PAVEMENT RECOMMENDATIONS
Based on the subsurface conditions encountered at the site, it is our opinion the proposed pavement
construction is feasible at the site from a geotechnical engineering point of view. It should be noted
that siltstone/sandstone bedrock was encountered at an approximate depth of 4-feet below existing
site grades in the general vicinity of Test Boring No. 4 during the initial drilling operations. The City of
Fort Collins requires that a minimum separation of 3-feet exist between the bottom of the pavement
structure to the top of potentially expansive and/or impermeable bedrock. Therefore, after the
Geotechnical Engineering Report - Pavement Thickness Evaluation
Fossil Creek Parkway Extension
Terracon Project No. 20006237
subgrade elevations have determined and prior to pavement construction, it may be necessary that a
further exploration be performed to delineate and/or determine the depth to bedrock.
It is suggested that a series of 3 to 4 foot depth backhoe test pits be excavated in the general vicinity
of Test Boring No. 4 to better define the depth to bedrock. It is recommended that during the -
backhoe test pit operations, a representative from Terracon and the City of Fort Collins be present to
document the soil profile and the depth to bedrock. If bedrock is encountered within the upper 3 feet r
of subgrade beneath the pavement section, the bedrock should be removed and replaced with an
approved fill material. The on -site overburden soils are suitable for reuse as fill material. The
replaced fill material should be moisture conditioned, placed in uniform lifts and compacted to at least
95 % of Standard Proctor Density ASTM D698. If during the additional backhoe test pit procedures,
bedrock is not encountered within 3-feet of final subgrade, no additional subgrade preparation is
necessary.
-T
Asphalt concrete underlain by crushed aggregate base course; full -depth asphalt pavement
underlain by crushed aggregate base course and non -reinforced concrete pavement are feasible "
alternatives for the proposed pavement sections. Based on the subsurface conditions encountered
at the site, it is recommended that the Fossil Creek Parkway extension be designed using an "R-
Value" of 13.
Pavement Design and Construction
Design of pavements for the project have been based on the procedures outlined in the 1993
Guideline for Design of Pavement Structures by the American Association of State Highway and
Transportation Officials (AASHTO), City of Fort Collins design criteria, and the following data. The
City of Fort Collins provided the equivalent daily axle loads (EDLAs) for the project. For flexible
pavement design, a design life of 20 years was utilized. Using a correlated design R-value of 13,
appropriate ESAL/day, environmental criteria and other factors, the structural numbers (SN) of the
pavement sections were determined on the basis of the 1993 AASHTO design equation.

Local drainage characteristics of proposed pavement areas are considered to vary from fair to good _
depending upon location on the site. For purposes of this design analysis, fair drainage
characteristics are considered to control the design. These characteristics, coupled with the
approximate duration of saturated subgrade conditions, results in a design drainage coefficient of 1.0
when applying the AASHTO criteria for design.

Fossil Creek Parkway Extension
Terracon Project No. 20005237
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 pounds per cubic inch
(pci) for the subgrade soil was determined by correlation to the laboratory tests results. A modulus of
rupture of 650 psi (working stress 488 psi) was used for pavement concrete. The rigid pavement
thicknesses for each traffic category were determined on the basis of the AASHTO design equation.
Recommended minimum thickness alternatives for flexible and rigid pavements, summarized for
each street, are as follows:

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 base course.
Aggregate base course should be placed in lifts not exceeding six inches and should be compacted
to a minimum of 95% Standard Proctor Density (ASTM D698).
Asphalt concrete and/or plant -mixed bituminous base course should be composed of a mixture of
aggregate, filler and additives, if required, and approved bituminous material. The bituminous base
and/or asphalt concrete should conform to approved mix designs stating the Hveem properties,
optimum asphalt content, job mix formula and recommended mixing and placing temperatures.
Aggregate used in plant -mixed bituminous base course and/or asphalt concrete should meet
particular gradations. Material meeting Colorado Department of Transportation Grading C or CX
specification is recommended for asphalt concrete. Aggregate meeting Colorado Department of
Transportation Grading G or C specifications is recommended for plant -mixed bituminous base
course. Mix designs should be submitted prior to construction to verify their adequacy. Asphalt

Maximum Allowable Slump.....................................................................4 inches
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. Other specifications outlined by the Colorado
Department of Transportation should be followed.
Longitudinal and transverse joints should be provided as needed in concrete pavements for
expansion/contraction and isolation. The location and extent of joints should be based upon the final
pavement geometry and should be placed (in feet) at roughly twice the slab thickness (in inches) on
center in either direction. Sawed joints should be cut within 24-hours of concrete placement, and
should be a minimum of 25% of slab thickness plus 1/4 inch. All joints should be sealed to prevent
entry of foreign material and dowelled where necessary for load transfer.

(Huntington Hills Parcel "J" Development)
Fort Collins, Colorado
EEC Project No. 1982124
Mr. Campbell:
Earth Engineering Consultants, Inc. (EEC) personnel have completed the evaluation you requested
for proposed improvements to Fossil Creek Parkway and Mail Creek Lane to the west of the
proposed multi -family development at Huntington Hills Parcel "J". Results of that evaluation are
provided with this report.
We understand that as a part of the Huntington Hills Parcel "J" development, Fossil Creek Parkwav
will be constructed from existing termination points to the east and west of the Parcel J development.
It is anticipated that improvements to the existing Fossil Creek Parkway and Mail Creek Lane to the
west of the Parcel J development will be required both as a result of traffic from the proposed
development and increased "cut through" traffic accessing Huntington Hills from South College
Avenue and the Miramont development area. The purpose of this report is to evaluate the structural
improvements required to the existing roadways because of traffic generated by the multi -family
development on Parcel`:J and from projected overall increased traffic.
To develop information on existing pavement and subgrade conditions, EEC personnel advanced
eight borings within the existing pavement areas. Six borings were drilled through the existing
Fossil Creek Parkway pavement and two borings advanced through existing Mail Creek Lane

pavement. The borings extended to depths of approximately 10 feet below top -of -pavement. Those
borings were performed using a truck -mounted, CME-45 drill rig equipped with hydraulic head
employed in drilling and sampling operations. After completion of the borings, the boreholes were
backfilled with the auger cuttings and the pavement surface patched with a commercial patching
compound.
Samples of the subsurface materials encountered in the borings were obtained using split -barrel and
Califomia barrel sampling procedures in general accordance with ASTM Specification D-1586. In
the California and split -barrel sampling procedures, standard sampling spoons are driven into the
ground by means of a 140-pound hammer falling a distance of 30 inches. The number of blows
required to advance the standard samplers is recorded and is used to estimate the in -situ relative
density of cohesionless materials and, to alesser degree of accuracy, the consistency of cohesive
soils. Additional samples were obtained from auger cuttings for Hveem R-value testing of the
subgrade materials. All samples obtained in the field were sealed and returned to the laboratory for
further examination, classification and testing.
Moisture content tests were completed in each of the recovered samples. The unconfined strength
of the samples was estimated using a calibrated hand penetrometer. Atterberg limits and washed
sieve analysis tests were completed to evaluate plasticity and percent of fines in the subgrades.
Swell/consolidation tests were performed on selected samples to evaluate the soil's tendency to
change volume with variation in moisture content. A Hveem stabilometer R-value test is presently
being performed and results of that test will be provided upon completion of the laboratory testing.
As a part of the testing program, all samples were examined in the laboratory by an engineer and
classified in accordance with the attached General Notes and the Unified Soil Classification System,
based on the soil's texture and plasticity. The estimated group symbol for the Unified Soil
Classification System is shown on the boring logs and a brief description of that classification is
included with this report.
Based on results of the field borings and laboratory testing, subsurface conditions can be generalized
as follows.

Along Fossil Creek Parkway, the pavement section consisted of 2 to 3 inches of asphaltic concrete
pavement overlying 16 to 21 inches of aggregate road base. Along Mail Creek Lane, the thickness
of the asphalt wearing surface was approximately 4 inches with approximately 12 to 14 inches of
aggregate base. The underlying subgrade soils consisted of low to moderate plasticity lean clay with
varying amounts of silt and sand. The lean clay was generally colored brown and light brown
although occasional gray and dark gray zones were observed. The lean clay soils were generally stiff
to very stiff with limited zones of soft or hard materials. The cohesive site soils generally showed
^
low potential for volume change with variation in soil moisture content although higher swell was
observed in one relatively dry sample obtained from near the College Avenue intersection.
These soils were generally relatively moist in their in -situ conditions although free water was not
observed in any of the borings at the time of drilling. Those boreholes were backfilled immediately
after completion precluding long-term observations of groundwater conditions. Fluctuations in
groundwater conditions can occur over time depending on variations in hydrologic conditions and ^
other conditions not apparent at the time of this report. Zones of perched and/or trapped may also be encountered at times throughout the year in more permeable zones interbedded in the subgrade --
soils. The location and amount of perched water can also vary over time depending on variations
in hydrologic conditions and other conditions not apparent at the time of this report.
Analysis and Recommendations
The existing pavement section on Fossil Creek Parkway generally includes 2 inches of asphalt ^
wearing surface overlying at least 16 inches of aggregate base course. A thicker asphalt wearing
surface was observed on Mail Creek Lane. The existing subgrade soils consist of low to moderate
plasticity lean clay. Based on previous work completed in this vicinity, we estimate the R-value of
the subgrade soils would be on the order of 7 to 11. R-value testing is being completed on a
representative sample obtained for this project and results of the R-value test will be provided upon
completion. For the evaluations completed at this time, we have estimate a conservative R-value
of 5 for the subgrade soils.
EEC Project No. 1982124

For this project, we have evaluated the needed improvements to Fossil Creek Parkwav and Mail
Creek Lane under three sets of traffic conditions. Those conditions include an evaluation of the
roadway under existing traffic conditions over the next 20 years, a roadway sufficient to carry the
total projected traffic over a 20 year design life and the roadway section required to carry the
projected traffic excluding traffic generated by the Parcel J multi -family project traffic. Traffic
volumes were obtained from the "Huntington Hills Apartments Transportation Impact Study"
prepared by Matt Delich and Ruth Rollins in November of 1998.
For all evaluation, 5% "truck" traffic was assumed with a truck load factor of 0.4. Fossil Creek
Parkway was assumed to be an arterial street when extended and a collector under present
configuration. Mail Creek Lane was assumed as a collector. For this evaluation, a Hveem
stabilometer R-value of 5 was used for the subgrade. After completion of the R-value testing, we
will re-evaluate the required additional asphalt section for each of the roadways. We anticipate the
numbers provided in this report are conservative by approximately %z inch of asphalt for each of the
sections.
Table 1 below indicates the thickness of the asphalt overlay required for each of the outlined traffic
scenarios.

current traffic projected over a 20-year life. To meet background traffic which would involve the
continuation of Fossil Creek Parkway without the construction of the Parcel J multi -family housing
units, an additional 4 and 2 inches of pavement should be placed on Fossil Creek Parkway and Mail
Creek Drive, respectively. Construction of the Fossil Creek Apartments would add a requirement _
for an additional '/z inch of asphalt on both Fossil Creek Parkway and Mail Creek Lane.

SECTION 01570
TREE PROTECTION
April 10. 2002
A. Tree Barriers:
All trees which will be preserved, but are within the limits of construction, must be protected from all
damage associated with construction. A sturdy, physical barrier (fluorescent orange in color) must be
fused in place around each tree for the duration of construction. This barrier will be placed no closer than
six (6) feet from the trunk, or one-half of the drip line, whichever is greater. The barrier itself must he
fixed so it cannot be moved easily, but the material can be flexible, such as orange safety fence attached
to metal T-posts driven into the ground, but must act as an effective deterrent to deliberate or accidental
damage of each tree. The Project Engineer or Manager must approve actual materials and location of
barrier.
The movement or storage of equipment, material, debris, or fill within these required protective barriers
is completely prohibited.
In situations where the construction will come closer to a tree than six (6) feet, the orange barrier must
still be erected. However, additional padding must be placed around the trunk of each tree starting at
ground level and proceeding up the trunk to a height of six or seven feet. Padding should be a minimum
eight (8) inches thick, and made of a material strong enough to protect the bark from accidental impacts
with hand tools or power equipment.
B. Accidental Poisoning:
During the construction, the Contractor shall not cause, or permit the cleaning of equipment or material
within the root zone of any tree. The Contractor shall not store or dispose of waste material including,
but not limited to; paints, solvents, asphalt, concrete, mortar, or any other material harmful to the life
of a tree, within the root zone of each tree, or group of trees.
C. Root Pruning Specifications:
When the cutting of tree roots is necessary, each final cut must be made as cleanly as possible for all roots
over three (3) inches in diameter using the following method:
1. The line of excavation will be drawn out and appropriate excavation equipment used to clear the area
at least six inches in front of the actual finished excavation line. Roots can then be cut using tools
such as axes, stump grinders, or trenchers.
2. Each root over three (3) inches in diameter will then be cut cleanly back to the excavation line using
stump grinder operated by an experienced licensed arborist. A sharp hand or bow saw is acceptable
for roots under three (3) inches in diameter. Axes and trenchers do not cut roots cleanly and will not
be used for final root cuts.
D. Contractor shall coordinate with the Owners' Field Representative prior to and during the tree
protection erection and root pruning activities. Owners' Field Representative, at his/her opinion, will
contact the City Forester and/or City Arborist for advice and approval of the to
protection measures
taken by the Contractor and also the City's advice and approval during the root pruning activities.

Dear Mr. Baker:
March 26, 2001
Enclosed is the EEC update, dated March 19, 2001, to their original report for Fossil
Creek Parkway/Mail Creek Lane prepared January 13, 1999. This update provides the
final R-value as specified in the 1999 report and thus completes that report. As noted in
their letter, they believe that the 1999 report is applicable for this project.
Should you have any questions regarding the report, please do not hesitate to contact
EEC or myself.
Sincerely,
TST, INC. CONSULTING ENGINEERS

E. No damaging attachments, wires, signs, permits or other objects maybe fastened by any means to any
tree preserved on this project.
Violation of Specifications and Penalties for Damaging Trees:
Any violation of these specifications will lead to penalties based on the type of violation and/or the
resulting damages, and may be grounds for the termination of this contract. The penalties will be assessed based on the amount of damage done and the total value of that tree, or _
group of trees, prior to the damage. The minimum penalty will be $100.00. Penalties for any damage
will be based on the total value of the tree as determined by the City Forestry Division staff and the —
severity of the damage as a proportion of the total value of that tree. This could include up to the full
value of the tree.
As an example, there are two American Elm trees to be preserved on another —
project. They are valued at $7, 960 and $6, 667 for the south and north trees
respectively. The south tree is approximately 100 inches in circumference,
therefore each inch is worth one -hundredth of the value, or $79.60 per inch.
Similarly, the north tree is 91 inches in circumference, making each inch worth
$73.26. To extend this to penalties paid, if one inch of the bark on the south tree
is scuffed, the penalty would be $100 (the minimum allowed); if two inches are
damaged, the penalty would be $159.20 and so on up to 50% of the
circumference of the trunk. If 50% or more is damaged, the full value of the tree
will be assessed as a penalty. (This example serves to illustrate how damages will
be assessed). —
This method of assessing penalties will be applicable to all trees not marked for removal on the project,
accidental poisoning and improper pruning. ._

Mr. Fuhrman:
Our geotechnical subsurface exploration for design of the referenced pavements was
submitted to the attention of Andover Development Partners on January 13, 1999. That
report provided pavement section recommendations based on an assumed R-value of 5
for in -situ subgrade soils although, based on prior experience in this area, we estimate the
R-value of those materials in the range of 7 to 11. The subgrade soils consisted of lean
clay with varying amounts of silt and sand. The January 13, 1999 report indicated that R-
value tests would be completed on the subgrade soils at a future date.
Results of R-value testing completed on a sample of sandy lean clay obtained from the ..
Fossil Creek Parkway area is attached. That testing indicates an R-value of 8 for the in -
situ subgrade materials. The tested R-value is slightly higher than the assumed R-value
of 5 used in the analysis for the January 1999 report. With the slightly higher R-value,
we believe the analysis completed for the 1999 report is applicable. With changes in
asphalt materials and local requirements, some modifications to the pavement sections as
recommended may be necessary. We would be pleased to assist in those evaluations.

Re: Pavement Section Recommendation

EEC Project No. 1982124
Mr. Campbell:
EARTH ENGINEERING
CONSULTANTS. INC.
Earth Engineering Consultants, Inc. (EEC) personnel previously completed field and
laboratory testing and provided recommendations for a pavement section for overlaying
Fossil Creek Parkway from College Avenue to Mail Creek Lane in Fort Collins. The
evaluation completed at that time indicated relatively dry, moderately plastic cohesive
soils near College Avenue with resulting swelling observed in those subgrade materials.
We have recently been asked to provide recommendations for addressing the swell
potential of the in -place subgrades at this location and to provide recommendations for
constructing Fossil Creek Parkway with a recycled asphalt/aggregate base with an asphalt
wearimz surFaCe. The Ee r?rCmmRndati- — n, n ,id-d w;th this rencrt
The in -place subgrade soils on Fossil Creek Parkway near College Avenue consist of low
to moderate plasticity sandy lean clay. Those materials at the time of our subsurface
exploration in June of 1999 were relatively dry and hard resulting in a laboratory
measured swell potential of greater than 5°10 at a confining pressure of 150 psf. To
reduce the potential for future swelling in the subgrades in this area, we recommend the
dry and hard subgrade materials be moisture conditioned and replaced as controlled and
compacted fill to reduce the swell potential of the lean clay soils. Soils throughout the
remainder of the Fossil Creek Parkway show higher moisture contents and lower swell
potential.

To develop a zone of low volume change fill beneath the pavements, it will be necessary
to remove the existing pavement structure and overexcavate the in -place subgrade
materials. We recommend those materials be removed to a depth of at least 2 feet below
top of subgrade elevation. The soils exposed at that depth should be scarified to a
minimum depth of 9 inches, adjusted in moisture content and compacted to at least 95%
of the materials maximum dry density as determined in accordance with ASTM ^
Specification D-698, the standard Proctor procedure. The moisture content of the _
scarified soils should be adjusted to be within the range of +/- 2% of standard Proctor
optimum moisture at the time of compaction. Fill soils required to develop the pavement
subgrade should consist of approved, low -volume change materials free from organic
matter and debris. The on -site sandy lean clay soils could be used for fill in this area with
proper moisture and density conditioning. We recommend the fill soils be placed in
loose lifts not to exceed 9 inches thick and adjusted in moisture content and compacted as
recommended for the in -situ scarified materials. The composite pavement section
recommended below could be placed directly on the prepared subgrades.
Concerning an alternative pavement section for the roadway, it would be possible to
recycle the existing asphalt surfacing in place with the existing aggregate base course to
develop a composite roadway section. The R-value of the subgrade soils as measured in
laboratory testing was 8 with a corresponding resilient modulus value of 5440 using the
A ::encan Association of Stare Highway and Transportation Officials (_AASHTO)
correlation between R-value and resilient modulus. An equivalent daily load axle rating
of 150 was provided by City of Fort Collins Engineering Department for this section of
Fossil Creek Parkway.
Based on the outlined subgrade and traffic conditions, we recommend the asphalt r _
surfacing above the prepared/recycled aggregate base course consist of 5 inches of hot
bituminous pavement. The pavement should be consistent with Colorado Department of
Transportation (CDOT) requirements for grading S for the surface mat and grading SX or
SG for the underlying section. The asphalt mix design should be prepared at 75 gyrations
using performance grade asphalt of PG 64-22.

Positive drainage should be developed away from the roadways to avoid wetting the base
or subbase materials. Wetting of the subgrade can result in premature failure of the
pavement sections.

The Contractor shall perform all work needed to ensure that said structures can be readily adjusted and shall have
all necessary materials on hand prior to commencing the work. The adjustments shall be made as noted below.
All structures shall be adjusted to be +/- 1/8" below the pavement surface.
The Contractor shall be responsible for immediately cleaning out all construction materials that may fall into
manholes, valve boxes, or other structures during the construction process. In the event that a structure was not
properly adjusted (i.e. too high or too low) or the structure was covered and not adjusted after the paving
operation, written notice will be given by the Engineer to the Contractor requiring the Contractor to make the
necessary adjustments within 5 working days. In the event that the structure is not adjusted within said time
frame; the Engineer shall have the right to engage a third party to complete the work, and to withhold the cost
of such work from payments due the Contractor.
If a structure is adjusted prior to an overlay operation, the Contractor shall place bituminous base material around
the structure as directed by the Engineer to insure that it will not be a hazard to vehicular traffic. This will be paid
for under the bid item for Asphalt Patching.
Adjust Valve Box — Valve boxes located within asphalt pavement shall be adjusted by removing the existing
pavement around the valve box, adjusting the valve by turning it to the proper grade, trimming the existing asphalt
