SCOPE
This report presents the results of our geotechnical investigation for the
light standards at the City Park tennis courts. The City Park tennis courts are
located southwest of the intersection of Roosevelt Street and Oak Street In Fort
Collins, Colorado. The existing tennis court facility is lighted by six light
standards located at the east and west ends and middle of the courts (Fig.1). The
City of Fort Collins Park Division is planning to remove the existing light
standards and replace them with new light standards to Improve the lighting at the
facility.
We Investigated the subsurface conditions In the vicinity of the tennis
courts to provide geotechnical design criteria and construction recommendations
for the new light standards. This report presents the results of our field and
laboratory studies and our conclusions, opinions and recommendations
regarding the proposed improvements. Our conclusions are summarized below.
SUMMARY OF CONCLUSIONS
1. The soils we encountered generally consisted of medium stiff to stiff
sandy clay fill over soft to stiff natural sandy clay and medium
dense silty sand.
2. Ground water was measured in our borings at depths of
approximately 7 feet to 17 feet below the existing ground surface.
3. Based on past performance of existing light standard foundations
and the subsurface conditions encountered, we believe the new
light standards may be founded on footings or pads bearing on well.
compacted fill or natural soil. Geotechnical design criteria for
footing foundations are presented In the report.
4. Excavations deeper than 5 feet will likely encounter soft or saturated
soil and/or ground water. Where ground water Is encountered in
excavations, dewatering may be necessary. Methods for dewatering
excavations are presented In the report.

SITE CONDITIONS
The City Park tennis courts are located southwest of the intersection of
Roosevelt Street and Oak Street In Fort Collins, Colorado (Fig. 1). The existing
tennis courts are located on the north portion of City Park. A trolley rail line Is
adjacent to the east of the tennis courts. A 3-feet high concrete retaining wall Is
located adjacent south and west of the tennis court fence. The ground surface
slopes down to the north toward Oak Street. A residential neighborhood bounds
the site to the north. City Park property bounds the site to the east, west and
south.
The existing tennis courts consist of a slab -on -grade court and chain -link
fence that encompasses three playing courts. A narrow strip of asphalt paving (1
to 2 feet wide) surrounds the outside of the fence. Existing light standards are
located along the east and west fence lines (inside the fence) and between each of
the three courts (Fig. 1). The existing light standards appear to be founded on a
footing or shallow pier. The City of Fort Collins Parks Department was not able to
provide us with specific Information regarding the existing light standard
foundations. The existing light standards appear to have performed well since
their construction.
PROPOSED CONSTRUCTION
We understand the City Intends to remove the existing light standards and
their foundations without entirely removing the existing slab -on -grade and
concrete retaining walls. New light standards will then be constructed to provide
better lighting for the tennis courts. At the time or our investigation, the City had
not determined the exact locations of the new light standards.
SUBSURFACE CONDITIONS
We drilled one boring at each of the four corners of the tennis court facility
for a total of four (4) borings. The borings were drilled outside of the fence in the
CITY OF FORT COLLINS

IF
Irrigated lawn that surrounds the facility. The approximate boring locations are
shown on Fig. 1. Our borings were drilled with a flinch diameter, continuous
flight auger and a truck -mounted drill rig. The drilling operations were observed
by our field engineer who logged the soils and obtained samples for laboratory
testing. Graphic logs of the soils found in our borings Including results of field
penetration resistance tests are shown on Figure 2. Results of our laboratory
tests are presented on Figs. 3 through 5 and are summarized In Table I.
Our borings penetrated 2 to 6 feet of medium stiff to stiff, moist sandy clay
fill over soft to medium stiff natural sandy clay and medium dense silty sand (TH-1
and TH-3) to the maximum depth drilled of 20 feet. Ground water was
encountered at depths ranging from 7 to 17 feet In each of the borings during
drilling, When the borings were checked several days after drilling, ground water
was measured In two borings (TH-1 and TH-3) at depths of 13 and 14 feet. Ground
water will likely affect construction of the light standards if foundations extend to
elevation 97 or deeper. Further discussion Is presented below.
The clay fill and natural sandy clays tested for swell/consolidation
exhibited slight compression to low swell (-0.1 to 0.0 percent). The clay fill and
sandy clays exhibited low plasticity and had 59 to 95 percent clay and silt size
particles (passing the —200 sieve). One sample of silty sand tested had 12 percent
silt sized particles. The silty sands are considered to be non -swelling.
LIGHT STANDARD FOUNDATIONS
Ground conditions and characteristics in the area of planned
Improvements consist of medium stiff to stiff sandy clay fill and soft to stiff
natural sandy clay In the near surface deposits. We do not know the depth of the
existing light standard foundations. We did not see evidence of movement or
distress to the existing structures. It appears that the existing foundations have
performed well over the life of the structures.
CITY OF FORT COLLINS 3
LIGHT STANDARDS AT
CITY PARK TENNIS COURTS
CTL I T PROJECT NO. FC03321
We considered foundation alternatives for the light standards that included
conventional footing foundations; shallow, drilled footings; and drilled friction
piers. A deep foundation system will encounter soft soils and ground water that
will make construction of piers difficult or impractical. Design criteria and
construction recommendations for conventional footings and drilled footings are
presented below.
Footings. Based on the subsurface conditions encountered, we believe the
planned light standards can be founded with footings or footing pads bearing on
the natural near surface soils. Footings or footing pads bearing on the near
surface clays and sands can be designed for a maximum soil bearing pressure of
1,500 psf.
Footing bearing elevation should be a minimum of 30 Inches below lowest
adjacent grade for frost protection. Footings or pads should have a minimum size
of 16 inches by 16 inches. These are minimum dimensions and larger footings
may be required to support foundation and wind loads. Alternatively, the light
standards could be founded using drilled footings or short piers that are at least
18 inches in diameter and 30 inches deep. Concrete could be poured "neat" Into
the drilled excavations. Drilled footings would require less removal of the existing
slab -on -grade than conventional "form and pour" techniques. The project
structural engineer should design steel reinforcement for footings.
Soft, unstable soils and ground water may be encountered during
construction if excavations are made deeper than 5 feet below the ground surface.
Our recommendations for mitigating these conditions are included below in the
Ground Water section.
Prior to the placement of reinforcing steel or concrete, the base and sides
of the excavation should be clear of debris, trash, and loose soil. Loose soil
should be removed to expose firm natural soil or compacted in place to a
minimum 95 percent of the maximum dry density as determined in accordance
with ASTM D 698. Excavations should not remain open for more than 2 days. Soil

LIGHT STANDARDS AT
CITY PARK TENNIS COURTS
CTL I T PROJECT NO. FC03321
within the excavation should remain in a moist condition. Moisture conditioning
may be required prior to the placement of concrete.
A representative of CTL I Thompson should observe the completed
foundation excavations prior to placing the forms to verify subsurface conditions
are as anticipated from our borings.
Lateral loads applied to footings or pads can be resisted by friction
between the concrete at the base of the footing or pad and the ground and by the
passive pressure of densely compacted backfill and/or undisturbed ground
against the sides of a footing or pad provided that soil will not be removed over
the life of the structure. A friction coefficient of 0.35 can be used between the
foundation concrete and the natural soil or backfill. The passive earth pressure
against a footing or mat can be calculated using an equivalent fluid density of 2T0
pet for undisturbed soil or engineered fill.
Slab -on -Grade Construction. We understand removal of the existing light
standards may require partial removal of the existing slabs -on -grade and
construction of new concrete slabs in some areas. Where new slabs are
constructed, some differential movement between existing slabs and new slabs
should be anticipated.
The designer may wish to consider dowelled connections of the new slab
and existing slab Interface. The potential for differential movement can also be
reduced by extending the slab removal area a distance (typically on the order of
two feet) beyond the excavation edges so that expected and normal settlement of
backfill is partially bridged by undisturbed material. Backfill settlement can be
reduced by compaction to 98 percent of standard Proctor maximum dry density
(ASTM D 698) at a moisture content within 2 percent of optimum. We do not
recommend rigid connections between foundation elements and slabs -on -grade.
For new stabs -on -grade we recommend the following additional precautions be
observed. These precautions will not eliminate slab -on -grade movement but will
reduce the potential for damage due to movement of slabs:
CITY OF FORT COLLINS 5
LIGHT STANDARDS AT
CITY PARK TENNIS COURTS
CTL I T PROJECT NO. FC03321
1. Slabs should be Isolated from retaining walls, columns or other slab
penetrations.
2. New stabs -on -grade should generally be constructed in a manner
similar to the existing construction. For example, if a 64nch gravel
section underlies the existing slab, a similar section with the new
slabs will reduce the potential for differential movement between the
two slabs. A gravel layer is typically recommended where ground
water Is within about 3 to 5 feet below the slab.
3. Frequent control joints should be provided in conventional slabs -on -
grade to reduce problems associated with shrinkage cracking and
curling. Panels that are approximately square generally perform
better than rectangular areas. We advocate an additional joint about
3 feet away from and parallel to the retaining walls.
Ground Water. Our borings encountered water at depths as shallow as 7 feet. If
excavations are to be deeper than 5 feet below grade, we recommend the
contractor anticipate soft soils and wet conditions that will result from water
seeping into excavations for the foundations. Soft soils or unstable excavations
caused by localized seepage can be stabilized by crowding coarse aggregate
(such as CDOT No. 4 or No. 57) Into the excavation using conventional
construction equipment. For excavations that will penetrate the ground water
surface, dewatering prior to excavation is recommended. Dewatering is
discussed in more detail below in the Excavations section.
ADDITIONAL CONSTRUCTION CONSIDERATIONS
Fill. We anticipated that minor amounts of fill might be necessary in areas where
existing grades have been disturbed by removal of the existing light standards.
The area to receive fill should be scarified, moisture -conditioned to within two
percent of optimum moisture content and compacted to at least 95 percent of
standard Proctor maximum dry density (ASTM D 698). The near surface, on -site
soils can be used as engineered fill providing they are free from organics, trash,
or other deleterious materials. If imported fill is needed, the soils should be low
swelling, sandy clays similar to the on -site soils, or granular soils. Highly plastic
and swelling clays and claystone are not desirable as imported fill because they
may cause problems associated with expansive soils. A sample of soils proposed

for import for fill should be submitted to our office for classification and approval
prior to hauling them to the site. We believe imported clay fill should be placed at
high moisture content to reduce the swell potential. Imported clay fills should be
moisture -treated to between optimum and 3 percent above optimum moisture
content, and sand fill or on -site soils within ±2 percent of optimum moisture
content. Fills should be compacted to at least 95 percent of standard Proctor
maximum dry density (ASTM D 698). The placement and compaction of
engineered fill should be observed and tested by our representative.
Excavations. Footing excavations In the near surface soils can be performed with
conventional trenchers or backhoes. Shallow ground water was encountered
below the site. We anticipate ground water will Impact the proposed construction
If excavations are 5 feet or more below the current ground surface.
Medium stiff to stiff clay fill and soft to medium stiff sandy clays will likely
be the predominant soils encountered during construction. According to the
Occupational Safety and Health Administration (OSHA) criterla, the fill and sandy
clay we encountered will classify as Type B soil, allowing excavation slopes of 1:1
(horizontal to vertical). The contractor's "Competent Person" on site should
Identify the soils encountered in excavations and refer to OSHA standards to
determine appropriate slopes.
Spoils plies should not be placed immediately adjacent to the excavations.
We recommend a distance back from the edge of the trench at least as great as
the depth of the trench.
Ground water was measured at depths of 7 to 17 feet below the existing
ground surface. Any excavations deeper than 5 feet will likely encounter soft or
saturated soil and/or ground water. Where ground water is encountered In
excavations, dewatering may be possible by sloping excavations to one or more
sumps where water can be removed by pumping. The sumps should be several
feet below the bottom of the excavations to pump water down through the soil
rather than up through the bottom of the excavation. Pumping water up through
CITY OF FORT COLLINS
LIGHT STANDARDS AT 7
CITY PARK TENNIS COURTS
CTL I T PROJECT NO. FC03321
the base of the excavation will likely result In destabilization of the base of the
excavation. The ground surface surrounding the excavation should be sloped to
direct runoff away from the excavation.
We recommend excavation backfill be placed in thin, loose lifts, moisture
conditioned to within 2 percent of optimum moisture content and compacted to at
least 98 percent of standard Proctor maximum dry density (ASTM D 698) In areas
below the slab. In unpaved, undeveloped areas excavation backfill should be
compacted to at least 90 percent of standard Proctor maximum dry density (ASTM
D 698). The placement and compaction of fill and backfill should be observed and
tested by a representative of our firm during construction.
CONCRETE
Concrete that comes Into contact with soils can be subject to sulfate
attack. We measured water-soluble sulfate concentrations in one sample from
this site. The concentration measured was 0.023 percent. Sulfate concentrations
less than 0.1 percent Indicate Class 0 exposure to sulfate attack for concrete that
comes into contact with the subsoils, according to the American Concrete
Institute (ACI). For this level of sulfate concentration, ACI Indicates any type of
cement can be used for concrete that comes Into contact with the subsoils. In our
experience, superficial damage may occur to the exposed surfaces of highly
permeable concrete, even though sulfate levels are relatively low. To control this
risk and to resist freeze -thaw deterioration, the water-to-cementitious material
ratio should not exceed 0.50 for concrete in contact with soils that are likely to
stay moist due to surface drainage or high water tables. Concrete should be air
entrained.
LIMITATIONS

observation; results of our laboratory tests; engineering analysis of field and
laboratory data; and our experience.
Our borings were located to provide us the needed picture of the
underground based on plans known at the time of our investigation. Variations
between the borings will occur.
A representative of our firm should be present during construction to
observe and test fill and backfill placement and foundation excavations. We
believe this investigation was conducted in a manner consistent with that level of
care and skill ordinarily used by geotechnical engineers practicing in this area at
this time. No warranty, express or Implied, is made. If we can be of further

LIGHT STRUCTURE SYSTEM SPECIFICATIONS
A. Playability Specifications
A.1. *Initial Light Levels
The average initial levels for the entire court area shall be 43.0 footcandles.
A.2. *Target Light Levels
The average target (maintained) light levels for the entire court area shall be 34.4
footcandles.
A.3. *Light Loss Factor
The light loss factor used to determine the target light levels shall be a
maintenance factor of .80.
AA *Uniformities
The uniformities of the playing field shall be measured by comparing the
maximum reading to the minimum reading. The ratio shall not exceed 1.86:1
maximum to minimum for the entire court area.
A.S. *Structural Strength
To prevent misalignment of any luminaires or damage to the crossarms or its
components, the crossarm, reflector, and its attachment to the pole shall be able
to structurally withstand winds of 100 mph with a 1.3 gust factor.
A.6. *Mounting Heights
To ensure proper aiming angles for reduced glare and to provide better
playability, the pole mounting heights from the playing field surface shall be 19
feet.
B. Maintenance Ease
B.1. Electrical Enclosure Fusing
To prevent multiple failures, an individual fuse shall be provided for each ballast
conductor except neutral conductors.
C. Durability
C.1. Enclosed Wiring
To protect from deterioration from exposure to the elements, all wiring shall be
contained inside the crossarms or pole.
C.2. Materials and Coatings
To facilitate adequate heat dissipation from the ballasts, the electrical enclosure
shall be fabricated of heavy gauge aluminum. The electrical enclosure shall be
further coated with a TGIF thermoset polyester powder paint finish to provide
protection from oxidation of the aluminum.
C.3. Internal Wire Rating
To ensure longer durability, internal wiring shall be routed away from ballast
cores, rated for at least 90 degrees C, suitable for the voltage and amperage
involved. Luminaire manufacturer shall supply U.L. temperature test of electrical
enclosure.
CA. Weather Proof Enclosure
To provide protection against weather -related elements, it shall be UL and CSA
rated to wet locations.
C.5. Pole Material
For added durability, the poles shall be high strength low alloy tapered tubular
steel meeting ASTM-A595 standards, and shall have a TGIC thermoset polyester
powder paint finish.
D. Safety
D.1. UL Listing
To provide independent assessment of equipment and system safety, the lighting
and electrical equipment shall have a U.L. listing. This listing shall be based upon
U.L. testing and evaluation of the compatibility of the structures, enclosures and
the components for use in combination with this application in addition to the
individual components being U.L. listed or recognized.
D.2. Grounding Lug within Electrical Enclosure
For the safety of personnel and protection of the equipment, one grounding lug
shall be supplied within the electrical enclosure, which is rigidly fastened to the
enclosure, sized to accept up to a 1/0 conductor.
D.3. Enclosed Wiring
Because the additional structures often required to support overhead wiring
systems can present safety hazards for players and spectators, all wiring shall be
contained inside the crossarms or the pole. Since the overhead is exposed to
wind, lightning, and other elements causing deterioration over time, underground
wiring, supplied by the installer, shall be enclosed within the pole and concrete
base.
D.4. Compliance to Specified Codes
The lightning equipment shall comply with the codes as specified including, but
not limited to:
National Fire Protection Asso (NFPA) 780 Lightning

lightning protection meeting standards established by NFPA 780 (National Fire
Protection Asso.)
At each structure, the contractor shall provide at least one copper -clad steel
ground rod of not less than 5/8 inches in diameter and not less than 10 feet in
length.
The ground rods shall be connected to the structure by a copper main down
conductor. This conductor shall be not less than a #2 conductor.
For steel poles, the main down conductor shall extend from the base of the steel
pole to the ground rods and shall be bonded to the steel pole and the equipment
