Re: Andersen Properties,LLC
Andersen rail siding, Case number USR-1501
Dear Ms. Lockman:
We have discussed the proposed rail siding with Mr. Paul Hungenberg of Hungenberg Produce, Inc., at
length, and negotiated a "Letter of Intent" between Andersen Properties, LLC and Hungenberg Produce,
Inc. We feel these negotiations have lessened the original concerns raised by Hungenbergs. We will
finalize an agreement between the parties before final commissioner approval of this project.
The most significant changes to our original application is at the request of Hungenbergs we are
dropping the proposed equipment storage shed. In addition, to accommodate the layout and flow of
Hungenberg's employee parking lot we are relocating the common fence between us.
Please review the enclosed "Letter of Intent" and call me at 302-9292, if you have additional questions.
We hope this diminishes conerns of Weld County Planning Commission, regarding issues originally
raised by Hungenberg Produce, Inc.
Sincerely,
ly 04,

Dear Sheri:
I am writing on behalf of my client, Andersen Properties, LLC, to request that the
improvements to his property be completed to the satisfaction of the Weld County Department
of Public Works and Planning Services in lieu of submitting an Improvements Agreement. My
client anticipates beginning construction September 7, 2005 and completing construction by
December 1, 2005.
In addition to this letter, I am forwarding a copy of the updated USR-1501 plat. As requested
in the USR Resolution, we have labeled the pages of the plat as USR-1501, and the
development standards have been included on drawing C-1.1. The USR boundary line has
been adjusted so that the east boundary line is common with the centerline of the Eaton Draw.
In a telephone conversation with you, you confirmed that the western limit of the R-1
(Residential) Zone District is common with the centerline of the Eaton Draw. With regard to
the Access and Utility Easement, the boundary of this easement has been included on the
Subdivision Exemption (SE-1051), and will become a recorded easement once the Subdivision
Exemption has been signed and recorded. I have also, attached a copy of the Approved
landscape/screening plan, grading plan, drainage plan, and construction details with this letter
for reference.
Dean Andersen with Andersen Properties, LLC has added a culvert crossing near the west
property line and adjusted the location of the landscaped berm along the south boundary line.
The purpose of the culvert is to direct off-site stormwater to the north side of his property. As
previously discussed with public works, stormwater detention is not a requirement of this
development. However, Dean has chosen to install a stormwater filtration system for the
purpose of cleaning the stormwater runoff from his rail site before discharging the water into
the Eaton Draw. By diverting off-site stormwater north of the earthen berm, the amount of off-
site flow passing through the filtration system will be minimized, increasing the life of the
filtration system.

As shown on the previous USR Plat, a 4'-high, landscaped berm was proposed to be installed
parallel to the south boundary line of Dean Andersen' s property; this berm was to be installed
entirely his property. With Hungenburg's approval, Dean will be locating the landscaped berm
so that the centerline of the berm will be located along the centerline of the boundary line. This
dictates that the northern half of the berm will be located on Dean's property and the southern
half will be located on Hungenburg' s property.
At your request, I have forwarded an email to Peter Schei with Weld County Public Works
discussing these changes to the USR and have asked that he forward you an email in response
to these changes.
Please contact Dean Andersen if you have questions regarding proceeding with installing the
improvements to the railroad spur. I will be out of the office from September 6 to September
12, returning on September 13 , so please direct all questions to Dean. Thank you for your
attention to this matter.

WELD COUNTY USR QUESTIONNAIRE
UNION PACIFIC RAILROAD-RAILROAD SPUR
PEI No. 04-020
1. Explain, in detail, the proposed use of the property.
This property will be used as a railcar loading area for processed, ready-to-ship recycled
materials collected at the Andersen's Sales and Salvage, Inc. property. This "loading
yard" will be open from 7 a.m. — 7 p.m., Monday through Saturday. This site will be a
load/unload-only facility surrounded by a 6'-tall chain link fence with a locked gate.
Tractor-trailer drivers will haul the material from the Andersen Salvage yard located at
1490 East 8a' Street to the loading site at the corner of WCR 39'/ and WCR 64 (O
Street), and pile the material next to the railroad tracks. Once or twice a week, Andersen
Salvage will fill empty rail cars left at the site that are then hauled to steel mills
throughout the country. No more than nine (9) rail cars will be stored on the rail spur at
any given time. A track hoe with a magnet will be used to move the piled material onto
the rail cars. A 40'x60' machinery/equipment storage building is proposed to be
constructed on this property to house the track hoe.
2. Explain how the proposal is consistent with the intent of the Weld County Code,
Chapter 22 (Comprehensive Plan).
This proposal is consistent with Chapter 22 of the Weld County Code as the site is
bordered by existing, approved industrial-use property, in a somewhat isolated location,
having good vehicle access. The use of this property should not create pollution, is
outside of any urban growth boundaries, does not interfere with any agricultural uses, and
is a cost-effective service and facility. This project is compatible with surrounding land
uses in terms of traffic, density, scale, dust, and noise, and is suitable for the land. The
use is a necessary public facility and service, and provides a necessary place for
recyclable material. This project is compatible with existing and future land uses in all
aspects—appropriate infrastructure exists that provides adequate access. This project
will allow for the rail transportation of recyclable materials in a safe and environmentally
sensitive manner. This project will reduce the wear on public roads. Monthly,
Andersen's Salvage currently trucks approximately 160 roundtrips to Pueblo, Colorado
(51,000 truck miles per month).
Finally, the proposed railroad extension will eliminate the need for Andersen Properties
LLC to continue to use the Western Sugar railroad spur that parallels 16th Street and
crosses the US 85 bypass. UPRR views this crossing as a dangerous crossing, and has
expressed that they would like to eliminate it in the future.

January 14,2005
's•-• 3. Explain how the proposal is consistent with the intent of the Weld County Code,
Chapter 23 (Zoning) and the zone district in which it is located.
The land proposed for the Union Pacific Railroad Spur is consistent with Chapter 23 of
the Weld County Code, specifically under Section 23-3-330, labeled the I-2 (Industrial)
Zone District. This property will be Industrial and will fall under description 3 of
category D (Use by Special Review), labeled "Commercial Junkyard or Salvage Yard."
This location is ideal, as the existing railroad ends within 20 feet of the property's edge.
The Weld County Code provides for this type of use by special review with applicable
performance, design and operation standards.
4. What types of uses surround the site? Explain how the proposed use is consistent
and compatible with surrounding land uses.
At the north side of the property are the Hoshiko Farms' fields that grow onions, feed
corn, pinto beans, alfalfa, and wheat. To the south of the property is the Hungenberg
Investments, LLC property, which is a farm produce packing and trucking establishment.
To the east is a private piece of farming property owned by Duane and Dorothy Zabka,
and to the west are Platte River Steel, Winograd's, and Big R Manufacturing (all are
heavy industry and are rail-served). Each of these businesses operates a trucking and
transporting type of operation.
Andersen previously leased this siding from UPRR for the loading of scrap. UPRR
assigned a switch/siding number of 816 to this spur (see attached). The proposed
operation of the property will not differ in any way from the previous and existing
activity that takes place in this area.
5. Describe, in detail, the following:
a. How many people will use this site?
Usually, one person will deliver the materials in a tractor-trailer and stack the material
at the site. Occasionally, two or three trucks may be in operation at once to drop off
the material. Each rail car requires about an hour to fill. A track hoe with a magnet
will be used to perform this duty and only requires one man to operate.
b. How many employees are proposed to be employed at this site?
No more than five individuals will be on the site at one time. No individual will be
required to staff the site at all times. This will be a load/unload site only, fenced with
a locked gate.
c. What are the hours of operation?
7 am—7 pm, Monday through Saturday.
Union Pacific Railroad-Railroad Spur
Pickett Engineering, Inc. Page 2 of 4
January 14,2005
d. What type and how many structures will be erected (built) on this site?
One building will be constructed for the storage of the loading machinery.
e. What type and how many animals, if any, will be one this site?
No animals will occupy this site.
f. What kind (type, size, weight) of vehicles will access this site and how often?
A track hoe with a magnet weighing approximately 50 tons will be stored
permanently on-site in the proposed storage shed. In addition, tractor-trailer truck(s)
will be depositing materials on the property.
g. Who will provide fire protection to this site?
The Eaton Fire Protection District has jurisdiction over this area.
h. What is the water source on this property? (Both domestic and irrigation)
The Eaton Draw serves as a drainageway and passes through the east end of the
property. A North Weld County Water District water main with a fire hydrant exists
approximately 700' west of the property. To the north of the existing fire hydrant, the
main's size is 8", and south of the hydrant the main is reduced to a 6" line. A "Will
Serve" letter is attached with this submittal.
i. What is the sewage disposal system on the property? (Existing and proposed)
A portable restroom is proposed for this property. Currently, no sewage disposal
system exists on the property. For this reason, we have only included a document
showing evidence of adequate water supply.
j. If storage or warehousing is proposed, what type of items will be stored?
Machinery—specifically, a track hoe with a magnet attached.
6. Explain the proposed landscaping for this site. The landscaping shall be
separately submitted as a landscape plan map as part of the application submittal.
Landscaping is proposed along the west side of the Eaton Draw. The trees will provide
screening for the properties to the east. And, by placing the trees adjacent to the draw,
they will be receiving an adequate water supply. The landscaping is shown on the Use by
Special Review plat plan. No additional landscaping is proposed for the remainder of
this site.
7. Explain any proposed reclamation procedures when termination of the Use by
Special Review activity occurs.
This will be a permanent facility with no plans for future reclamation.
Union Pacific Railroad-Railroad Spur
Pickett Engineering, Inc. Page 3 of 4
January 14,2005
8. Explain how any stormwater drainage will be handled on the site.
Because of the proximity of the site to the Eaton Draw, the Public Works department is
willing to waive any stormwater detention requirements, according to a conversation with
Peter Schei. Due to the size of the Eaton Draw basin, we understand that the time it
would take for the subject property to peak during a 100-year storm event would be much
shorter than the time for the Eaton Draw to peak during this same event—meaning that
the maximum stormwater flow from the subject property will have entered the draw long
before the draw has reached its maximum flow rate. This offset in peaks is the basis for
waiving stormwater detention.
However, the owner is proposing to install a stormwater treatment facility on this
property. During the minor storms, stormwater runoff will be directed toward a proposed
sediment basin. The sediment basin will serve as a stilling basin, where larger sediment
particles will fall out of the water. From the sediment basin, the stormwater will flow
into a proposed filtration system. The filtration system will remove sediments as well as
most other pollutants. From the filtration system, the stormwater will be released into the
Eaton Draw. When a major storm event occurs, the initial runoff flows will pass through
the treatment system and once the system has reached its capacity, the remaining
stormwater flow will flow directly into the draw. Because the majority of the pollutants
are transported with the initial stormwater flows, we believe that the treatment facility
will be effective during a major storm event.
9. Explain how long it will take to construct this site and when construction and
landscaping is scheduled to begin.
Once a building permit is obtained, construction will begin immediately and will last
approximately a month.
10. Explain where storage and/or stockpile of wastes will occur on this site.
There will be no storage of wastes on this site.

USR DRAINAGE REPORT
Union Pacific Railroad - Railroad Spur
Weld County, Colorado
1. General Legal Description
The Union Pacific Railroad currently owns a 9.084-acre lot located along the
southern portion of parcel 13801A in the S2NE4 of Sec. 29 T6N R65W, Except the
part lying East of the East Line of the Bliss Lateral (9RR 2D), Weld County,
Colorado.
2. General Location with Respect to Public/Private Roads
The proposed USR is accessed via WCR 39'A, east of Highway 85 and north of O
Street.
3. Names and Descriptions of the Surrounding Developments (One-half Mile)
There are no developments within one-half mile of the property.
4. General Description of Proposed Subdivision Property
a. Area
The property is approximately 9.08 acres in size. This property is currently owned
by the Union Pacific Railroad and lies entirely within the Railroad right-of-way.
At the north side of the property are the Hoshiko Farms' fields that grow onions,
feed corn, pinto beans, alfalfa, and wheat. To the south of the property is the
Hungenberg Investments, LLC property, which is a farm produce packing and
trucking establishment. To the east is a private piece of farming property owned
by Duane and Dorothy Zabka, and to the west are Platte River Steel, Winograd's,
and Big R Manufacturing (all are heavy industry and are rail-served). Each of
these businesses operates a trucking and transporting type of operation.
b. Ground Cover
Currently, a large portion of the site is bare ground in the area to the north of the
Hungenberg Investments, LLC property. East of that, the remainder of the
property is lightly covered with grass vegetation.
c. General Topography
The property slopes at an overall average of 1% from the northwest corner across
the entire property until it runs into the Eaton Draw located at the east boundary of
the lot. An existing railroad ends within 20' of the western border of the lot, but
Pickett Engineering, Inc.
Union Pacific Railroad-Railroad Spur
USR Drainage Study
January 14,2005
Page 2 of 4
there exists a berm through the center of the entire property from west to east
where the track existed in the past. Also running from west to east and along the
north side of the berm is an irrigation ditch that empties into the Eaton Draw.
These geographical features of the ditch to the north and the berm cause all flows
from the north to stay on the north side of the property. All flows south of the
railroad centerline flow west to east within the natural contours until emptying into
the Eaton Draw.
d. General Soil Conditions
A •
Olney fine sandy loam and Otero sandy loam, both well-drained soils, make up the
majority of the property. The NRCS soil classification [for well drained] soils is
B.
e. Irrigation Ditches or Laterals
Hoshiko Farm's irrigation ditch runs along the northern side of the railroad berm
that flows from west to east across the property. At the eastern edge of the
property is the Eaton Draw that flows north to south. An irrigation ditch that
services the farm at the southeast edge of the property will be moved south of the
property boundary.
1. Drainageways
The only apparent drainage channel that flows through the property is the ditch on
the north side of the berm. The lower half of the property has a slight natural
drainageway from west to east that empties into the Eaton Draw at the east border
of the property.
5. Description of the Drainage Basin and Sub-Basins
a. Major Drainageway Planning Studies
N/A
b. Major Drainage Characteristics
1. Existing Major Basin
B-1 can be delineated beginning at the west edge of the property along the
railroad centerline and includes the entire bottom-half of property to the east,
until the railroad centerline meets the eastern border of the property. All flow

occurring on the northern side of the berm will be directed east—by both the
berm and the existing irrigation ditch—to the Eaton Draw.
2. Existing Sub-Basins
There are no existing sub-basins.
c. Nearby Irrigation Ditches/Laterals that will be Affected
The Eaton Draw is the only ditch in the area affected by the runoff of the Union
Pacific Railroad property.
d. The Historic Drainage Flow Pattern of Property
The historic drainage flow pattern for this property travels east to the existing
drainage channel known as the Eaton Draw. Flow within the channel continues
south to the Cache La Poudre River.
6. Drainage Facility Design Concepts and Details for the Proposed Property
a. Compliance with Off-Site Runoff Considerations
It is not the intent of the development to adversely affect the surrounding
properties or the Eaton Draw.
b. Anticipated and Proposed Drainage Patterns
The proposed drainage pattern will follow the historic flow patterns of the
development. It is the intent of the development to prevent adverse effects to the
surrounding properties. We have determined that—with the proposed
improvements to the site—the percent impervious will increase to 14. For this
property, the proposed improvement includes a 40'x60' storage shed, a gravel-
packed driveway from the access road off WCR 3972 to the property edge, with a
gravel-packed stockyard/loading area along the railroad and an additional
turnaround area for the tractor trailors that will drop off scrap material. These
improvements will slightly increase the stormwater runoff from the site, but will
not negatively impact any irrigation ditches or adjacent property owners. Due to
the close location of the Eaton Draw, a detention facility will not be placed on this
site. A storm filter system with a sediment basin will be placed east of the
proposed turn-around area(see plans).

L=length of overland flow(500 ft maximum for non-urban land uses, 300 ft maximum for urban
land uses)
S=average basin slope(ft/ft)
Equation RO-3 is adequate for distances up to 500 feet. Note that, in some urban watersheds,the
overland flow time may be very small because flows quickly channelize.
2.4.2 Overland Travel Time. For catchments with overland and channelized flow, the time of
concentration needs to be considered in combination with the overland travel time,t,, which is calculated
using the hydraulic properties of the swale, ditch, or channel. For preliminary work,the overland travel
time, r„ can be estimated with the help of Figure RO-1'or the following equation (Guo 1999):
V=C,y5„," (RO-4)
in which:
V=velocity(ft/sec)
C.=conveyance coefficient(from Table RO-2) d
Sw=watercourse slope(ft/ft)

Heavy meadow 2.5
Tillage/field 5
Short pasture and lawns 7
Nearly bare ground 10
Grassed waterway 15
Paved areas and shallow paved swales 20
The time of concentration, 4, is then the sum of the initial flow time,t,, and the travel time, r„as per
Equation RO-2.
2.4.3 First Design Point Time of Concentration in Urban Catchments. Using this procedure,the time
of concentration at the first design point (i.e.,initial flow time,t,)In an urbanized catchment should not
exceed the time of concentration calculated using Equation RO-5.

Based in part on the data collected by the District since 1969, an empirical relationship between C and
the percentage imperviousness for various storm return periods was developed. Thus,values for C can
be determined using the following equations(Urbonas, Guo and Tucker 1990).
CA =KA + (1.31i' —1.44i2 +1.135i—0.12)for CA≥0, otherwise CA=0 (RO-6)
C0 =K0 + (0.8581' -0.786i2 +0.774i+0.04) (RO-7)
CB = (C +CcD)/2

Northern Colorado Geotech Project No. 101-04
Northern Colorado Geotech has completed a geotechnical engineering exploration for the proposed
structure to be located on the strip of land located near Weld County Road 39% and 64, north of
Greeley, Colorado. This study was performed in general accordance with our proposal number
P04023g dated May 19, 2004.
The subsurface soils at the site consisted of sandy lean clay and silty sand with gravel. The results
of our field exploration and laboratory testing indicate that the soils have low expansive potential and
low load bearing capabilities.
Based on the anticipated construction and the results of our engineering exploration, it is our opinion
that the proposed structure may be supported on a spread footing foundation system. Slab on
grade may be utilized for the interior floor system.
If you have any questions concerning this report or any of our consulting services, please do not
hesitate to contact us.
Sincerely,
NORTHERN COLORADO GEOTECH

PROPOSED STRUCTURE
ANDERSEN PROPERTIES-WCR 391/2 AND 64
GREELEY, COLORADO
NORTHERN COLORADO GEOTECH
PROJECT NO. 101-04
JULY 13, 2004
SCOPE
This report contains the results of our geotechnical engineering exploration for the proposed
structure to be located near Weld County Roads 39% and 64, north of Greeley, Colorado.
This report includes descriptions of, and geotechnical engineering recommendations relative to:
• subsurface soil and bedrock conditions
• groundwater conditions
• foundation design and construction
• drainage
• floor slab design and construction
• earthwork
The recommendations contained in this report are based upon the results of field and laboratory
testing, engineering analyses, and experience with similar soil conditions, structures and our
understanding of the proposed project.
SITE CONDITIONS
The site is located at the south end of an agricultural field. Surface drainage is poor to fair to the
east and/or southeast. The property is bordered to the south by railroad tracks. Agricultural fields
are located to the north, west and east. An existing residence is located further to the east near
Weld County Road 41.
PROPOSED CONSTRUCTION
As we understand it, the project will likely consist of building a 60 foot by 40 foot slab on grade
structure near the western property boundary and determining the soil profile for a railroad spur on
the property.

SITE EXPLORATION
A total of three test borings were drilled on June 7, 2004. The borings were drilled to approximate
depths of 15 feet at the locations shown on the Site Plan, Figure 1. All borings were advanced with
a truck-mounted drilling rig, utilizing 4-inch diameter solid stem augers.
The borings were located in the field by pacing from property lines and/or existing site features.
Relative surface elevations at the boring locations were obtained by interpolation from a
topographic map provided by King Surveyors. The accuracy of boring locations and elevations
should only be assumed to the level implied by the methods used to determine each.
Lithologic logs of each boring were recorded by an engineering geologist during the drilling
operations. At selected intervals, samples of the subsurface materials were taken by driving split-
spoon and/or ring samplers. Standard penetration measurements were recorded while driving a
split-spoon and/or ring sampler into the subsurface materials. The standard penetration test is a
useful index in estimating the density of the materials encountered.
Groundwater conditions were evaluated in each boring at the time of subsurface exploration, and
one day after the drilling.
Laboratory Testing
The samples retrieved during the subsurface exploration were returned to our laboratory for
observation by the project manager. The soils were classified in general accordance with the
Unified Soil Classification System. At that time, the field descriptions were confirmed or modified
and an applicable laboratory testing program was formulated. Boring logs were prepared and are
attached with this report.
Laboratory tests were conducted on selected samples and are presented on the boring logs and
attached laboratory test sheets. The test results were used for the geotechnical engineering
analyses, and the development of foundation and earthwork recommendations.
Selected samples were tested for the following engineering properties:
• Water Content • Atterberg Limits
• Dry Density • Percent Fines
• Consolidation • Expansion
• Compressive Strength • Resistivity
• pH

SUBSURFACE CONDITIONS
Soil Conditions
Soils at the site generally consisted of sandy lean clay to depths of approximately 6% to 15 feet.
The clay soils are underlain by silty sand with gravel in Test Borings 2 and 3. Summary boring logs
are attached with this report.
Groundwater Conditions
Groundwater was not observed in any test boring at the time of field exploration, nor when checked
one day after the drilling. These observations represent groundwater conditions at the time of the
field exploration, and may not be indicative of other times, or at other locations. Groundwater
conditions can be expected to fluctuate with varying seasonal and weather conditions, and other
factors.
Field Test Results
Field test results indicate that the clay soils vary from medium to stiff in consistency. The sand
soils vary from loose to medium dense in relative density.
Laboratory Test Results
Laboratory test results indicate that the soils have low expansive potential and low load bearing
capabilities.
DESIGN RECOMMENDATIONS
Foundation Design
Based on the results of our subsurface exploration and the results of the laboratory testing, it is our
opinion that a spread footing foundation system may be used for support of the proposed structure.
The footings should be placed on undisturbed soils and/or engineered fill material.
Design and construction recommendations for foundation systems and other earth connected
phases of the project are outlined below.

Andersen Properties
Northern Colorado Geotech Project No. 101-04
Footing Foundations
Based on the results of our subsurface exploration and laboratory testing, it is our opinion that a
spread footing foundation system bearing upon undisturbed soil and/or engineered fill may be used
for support of the proposed structure. The footings may be designed for a maximum bearing
pressure of 1,500 psf. The design bearing pressure applies to dead loads plus design live load
conditions. The design bearing pressure may be increased by one-third when considering total
loads that include wind or seismic conditions.
Exterior footings should be placed a minimum of 30 inches below finished grade for frost protection
and to provide confinement for the bearing soils. Finished grade is the lowest adjacent grade for
perimeter footings.
Footings should be proportioned to reduce differential foundation movement. Proportioning on the
basis of equal total movement is recommended; however, proportioning to relative constant dead-
load pressure will also reduce differential movement between adjacent footings. Total movement
resulting from the assumed structural loads is estimated to be on the order of 3/4 inch or less.
Differential movement should be on the order of 1/2 to 3/4 of the estimated total movement.
Additional foundation movements could occur if water from any source infiltrates the foundation
soils; therefore, proper drainage should be provided in the final design and during construction.
Foundations and masonry walls should be reinforced as necessary to reduce the potential for
distress caused by differential foundation movement. The use of joints at openings or other
discontinuities in masonry walls is recommended.
Foundation excavations should be observed by Northern Colorado Geotech. If the soil conditions
encountered differ significantly from those presented in this report, supplemental recommendations
may be required.
Surface Drainage
Positive drainage should be provided during construction and maintained throughout the life of the
proposed project. Infiltration of water into utility or foundation excavations must be prevented
during construction. Planters and other surface features which could retain water in areas adjacent
to the building or pavements should be sealed or eliminated. In areas where sidewalks or paving
do not immediately adjoin the structure, we recommend that protective slopes be provided with a
minimum grade of approximately 5 percent for at least 10 feet from perimeter walls. Backfill
r
4
Pickett Engineering
Andersen Properties
Northern Colorado Geotech Project No. 101-04
against footings, exterior walls, and in utility and sprinkler line trenches should be well compacted
and free of all construction debris to reduce the possibility of moisture infiltration.
Downspouts, roof drains or scuppers should discharge into splash blocks or extensions when the
ground surface beneath such features is not protected by exterior slabs or paving. Sprinkler
systems should not be installed within 5 feet of foundation walls. Landscaped irrigation adjacent to
the foundation system should be minimized or eliminated.
Floor Slab Design and Construction
Some differential movement of slab-on-grade floor systems is possible should the subgrade soils
become elevated in moisture content. To reduce potential slab movements, the subgrade soils
should be prepared as outlined in the earthwork section of this report.
Additional floor slab design and construction recommendations are as follows:
• Positive separations and/or isolation joints should be provided between slabs and all
foundations, columns or utility lines to allow independent movement.
• Control joints should be provided in slabs to control the location and extent of
cracking.
• Interior trench backfill placed beneath slabs should be compacted in accordance
with recommended specifications outlined below.
• In areas subjected to normal loading, a minimum 4-inch layer of sand, clean-graded
gravel or aggregate base course should be placed beneath interior slabs.
� r
• Floor slabs should not be constructed on frozen subgrade.
Exterior slabs-on-grade, exterior architectural features, and utilities founded on, or in backfill may
experience some movement due to the volume change of the backfill. Potential movement could
be reduced by:
• minimizing moisture increases in the backfill
• controlling moisture-density during placement of backfill
• using designs which allow vertical movement between the exterior features and
adjoining structural elements
5
Pickett Engineering
Andersen Properties
Northern Colorado Geotech Project No. 101-04
• placing effective control joints on relatively close centers
General Earthwork
All earthwork on the project should be observed and evaluated by Northern Colorado
Geotech. The evaluation of earthwork should include observation and testing of
engineered fill, subgrade preparation, foundation bearing soils, and other geotechnical
conditions exposed during the construction of the project.
Site Preparation
Strip and remove existing vegetation, debris, and other deleterious materials from proposed
building and pavement areas. All exposed surfaces should be free of mounds and
depressions which could prevent uniform compaction.
Stripped materials consisting of vegetation and organic materials should be wasted from the
site, or used to revegetate landscaped areas or exposed slopes after completion of grading
operations.
If unexpected fills or underground facilities are encountered, such features should be
removed and the excavation thoroughly cleaned prior to backfill placement and/or
construction.
It is anticipated that excavations for the proposed construction can be accomplished with
conventional earthmoving equipment.
The individual contractor(s) is 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.
Fill Materials and Placement
All exposed areas which will receive fill should be scarified to a minimum depth of eight
inches, conditioned to near optimum moisture content, and compacted.
The placement of soils on the site should be observed by Northern Colorado Geotech. The
fill should be assessed for suitability of use in the proposed fill and tested for placement
including compaction percentage and moisture content.
6

Northern Colorado Geotech Project No. 101-04
Engineered fill should be placed and compacted in horizontal lifts, using equipment and
procedures that will produce recommended moisture contents and densities throughout the
lift. Recommended compaction criteria for engineered fill materials are as follows:
Clean on-site soils or approved imported materials may be used as fill material.
Imported soils (if required) should conform to the following:
Percent fines by weight
Gradation fASTM C1361
6" 100
3" 70-100
No. 4 Sieve 50-100
No. 200 Sieve 60 (max)

Scarified subgrade soils 95
On-site and imported fill soils:
Beneath foundations 95
Beneath slabs 95
On-site or imported clay soils should be compacted within a moisture con ent range of 2
percent below, to 2 percent above optimum. Granular soils should be compacted within a
moisture range of 3 percent below to 3 percent above optimum unless modified by the
project geotechnical engineer.
GENERAL COMMENTS
The analysis and recommendations presented in this report are based upon data obtained from
borings performed to obtain representative subsurface conditions at the site. Variations in the soil

between borings will occur. Northern Colorado Geotech should be present during construction to
observe the excavation and construction procedures and confirm or modify our recommendations.
The scope of services for this project does not include either specifically or by implication any
environmental assessment of the site.
This report has been prepared in accordance with generally accepted geotechnical engineering
practices in this area at this time. No warranties, either express or implied, are intended or made.

Dear Sheri:
The following responds to your March 16, 2005 email to Michael Hein:
Ditch Relocation: Union Pacific owns the property where the ditch is currently located. No
contact has been made with the owner of the land to the south where the ditch is proposed to
be relocated; an agreement has yet to be initiated regarding ditch relocation. According to
�— online Weld County records, Hungenberg Investments, LLC UND owns the property. To
our knowledge, the ditch is used for irrigating the farm fields south and east of the
Hungenberg building south of the UP property.
Final Topography: A drawing has been prepared to reflect the proposed topography of the
site. The drawing shows the 6'• elevation change and has cross-sections drawn to reflect the
proposed grading at a point 300' west of the scale, and 140' east of the scale (see attached).
Additionally, as requested by Char Davis of the Weld County Health Department, Mr.
Andersen has provided an information sheet regarding the noise level of the operating
equipment, attached.
Sheri, feel free to call me with any questions or concerns.
Sincerely,
PICKETT ENGINEERING, INC.
