MEMORANDUM
To: John Ed Singleton
CC: Project File
From: Jeremy Beard, Baseline Engineering
Date: August 13, 2014
Re: Septic System Check— Circle B Land Company Facility
We have reviewed the existing septic permit (SP-0400015) and believe that the existing septic
system is sufficiently sized to handle the proposed changes to the site. According to the proposed
site changes, the existing structure will be remodeled into an office with ten employees. The
predicted sanitary wastewater flow generated from these 10 office employees is 150 gallons per
day.
Using the new regulations and a predicted sanitary wastewater flow of 150 gallons per day, the
septic tank is required to be 400 gallons. The existing septic tank is a 1,000 gallon tank making it
adequately sized.
We correlated the percolation rate of 14.7 minutes per inch in the existing septic permit to a Long-
Term Acceptance Rate of 0.80 gallons per day per square foot. Taking a 70 percent reduction in
absorption area for the use of chambers the required soil treatment area is 132 square feet. The
existing soil treatment trench area is 549 square feet.
Based on the attached calculations and septic permit SP-0400015 we believe the existing septic
system is capable of handling the proposed changes to the site.
If you have any questions please feel free to contact me at (303) 940-9966 x 212

Residence and Septic System
Northeast Corner of Weld County Roads 70 and 85
I Weld County, Colorado
• Terracon Project No. 21035059
' Terracon has completed a geotechnical engineering exploration for the proposed residence and
septic system to be located at the northeast corner of Weld County Roads 70 and 85 in Weld County,
I Colorado. This study was performed in general accordance with our proposal number P2103066g
dated May 20, 2003.
I The results of our engineering study, including the boring location diagram; laboratory test results,
test boring records, and the geotechnical recommendations needed to aid in the design and
construction of foundations and other earth connected phases-of this project are attached.
I •
The subsurface soils at the site consisted of clayey sand underlain by sandstone, siltstone, and
I
claystone bedrock. The results of our field exploration and laboratory testing indicate that the
• bedrock at the site has a low expansion potential. The bedrock at anticipated foundation bearing
depth has a high load bearing capability.
I
Based on the geotechnical engineering analyses, subsurface exploration and laboratory test results, it
is our opinion that the proposed residence may be supported on a spread footing foundation system.
Given the engineering characteristics of near surface claystone bedrock, which may support slabs,
consideration should be given to removal of certain portions of expansive subgrade soils beneath
Islabs, and replacement with non-expansive soils. Slab heave on the order of about 1 inch is possible
for slabs bearing within 3 feet of claystone bedrock. If no movement can be tolerated, consideration
should be given to use of structural floor systems.
•
I The sandstone bedrock encountered at anticipated foundation bearing elevation contained thin . ..
claystone lenses that have low expansion potential. Areas of thickened claystone bedrock may be
Iencountered during excavation of the basement/foundations that may contain more expansive

SEPTEMBER 26, 2003
' INTRODUCTION
This report contains the results of our geotechnical engineering exploration for the proposed residence
and septic system to be located at the northeast corner of Weld County Roads 70 and 85 in Weld
County, Colorado.
The purpose of these services is to provide information and geotechnical engineering
recommendations relative to:
• subsurface soil and bedrock conditions
' • groundwater conditions
• foundation design and construction
• basement construction
• lateral earth pressures
• floor slab design and construction
• septic systems
• earthwork
• drainage
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.
PROPOSED CONSTRUCTION -
Terracon understands the site will be developed with a single story 3-bedroom residence with a
basement. Additional site infrastructure will include construction of a septic system. Structural loads
for the proposed residence were not available, however, Terracon assumes wall and column loads will
not exceed 3 kips per lineal foot and 30 kips, respectively. Site grading plans were not provided,
however, cuts and fills at the site are anticipated to be 5 feet or less.

SITE EXPLORATION
The scope of the services performed for this project included a site reconnaissance by a geotechnical
engineer, a subsurface exploration program, laboratory testing and engineering analyses.
Field Exploration
Three test borings were drilled on September 8, 2003. The borings were drilled to approximate depths
of 8 to 25 feet at the locations shown on the Site Plan, Appendix A. Two borings were drilled within the
footprint of the proposed residence. One (1) soil profile boring and six (6) percolation test holes were
drilled in the location of the proposed septic system. Percolation tests were conducted in general
accordance with Weld County requirements. 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 the client. Ground surface elevations at each boring location
were obtained by measurements with an engineer's level from a temporary bench mark (TBM) shown
on the Site Plan. 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 the field technician during the drilling operations. At
selected intervals, samples of the subsurface materials were taken by driving split-spoon and ring-
barrel samplers.
' Penetration resistance measurements were obtained by driving the split-spoon and ring-barrel
samplers into the subsurface materials with a 140-pound hammer falling 30 inches. The penetration
' resistance value is a useful index in estimating the consistency, relative density or hardness of the
materials encountered.
' Groundwater conditions were evaluated in each boring at the time of site exploration, and 5 days after
completion of drilling.
' Laboratory Testing
' All samples retrieved during the field exploration were returned to the laboratory for observation by the
project geotechnical engineer and were classified in accordance with the Unified Soil Classification
System described in Appendix C. Samples of bedrock were classified in accordance with the general
notes for Bedrock Classification. At that time, the field descriptions were confirmed or modified as

' necessary and an applicable laboratory testing program was formulated to determine engineering
properties of the subsurface materials. Boring logs were prepared and are presented in Appendix A.
' Laboratory tests were conducted on selected soil and bedrock samples and are presented on the
boring logs and in Appendix B. The test results were used for the geotechnical engineering analyses,
' and the development of foundation and earthwork recommendations. All laboratory tests were
performed in general accordance with the applicable local or other accepted standards.
' Selected soil and bedrock samples were tested for the following engineering properties:
• Water Content
' • Dry Density
• Consolidation/Expansion
SITE CONDITIONS
The site was located in an agricultural area and was undeveloped at the time of our site visit. The site
was vegetated with native weeds and grasses. Surface drainage sloped gently to the northeast. The
site was bordered to the north and east by undeveloped land, to the south by Weld County Road 70
and to the west by Weld County Road 85.
' SUBSURFACE CONDITIONS
ISoil and Bedrock Conditions
As presented on the Logs of Boring, surface soils to depths of 1'/: to 3 feet consisted of clayey sand.
' The materials underlying the surface soils and extending to the maximum depth of exploration
consisted of sandstone, siltstone, and claystone bedrock.
' Field and Laboratory Test Results
Field test results indicate that the sand soils are medium dense in relative density. The underlying
' bedrock varies from weathered to hard in hardness. Laboratory test results indicate that claystone
materials at shallow depth have a low expansion potential.

Groundwater was not observed in any test boring at the time of the field exploration. However, when
I
checked 5 days after drilling, groundwater was measured at approximate depths of 24 feet, in test
borings B-1 and B-2. 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 levels can be
expected to fluctuate with varying seasonal and weather conditions.
' ENGINEERING ANALYSES AND RECOMMENDATIONS
Geotechnical Considerations
IThe site appears suitable for the proposed construction based upon geotechnical conditions
encountered in the test borings. -I Based on the geotechnical engineering analyses, subsurface exploration and laboratory test results,
it is our opinion that the proposed residence may be supported on a spread footing foundation
I
system. Given the engineering characteristics of near surface claystone bedrock, which may
support slabs, consideration should be given to removal of certain portions of expansive subgrade
I4

Terracon Project No.21035059 Terracon
soils beneath slabs, and replacement with non-expansive soils. Slab heave on the order of about 1
inch is possible for slabs bearing within 3 feet of claystone bedrock. If no movement can be
tolerated, consideration should be given to use of structural floor systems.
The sandstone bedrock encountered at anticipated foundation bearing elevation contained thin
' claystone lenses that have low expansion potential. Areas of thickened claystone bedrock may be
encountered during excavation of the basement/foundations that may contain more expansive
potential than the materials sampled during our exploration. Should such conditions be encountered,
' additional recommendations will be necessary.
Design and construction recommendations for foundation systems and other earth connected phases
of the project are outlined below.
Foundation Systems
Due to the properties of the on-site soils and anticipated loading conditions, spread footing foundations
' bearing upon undisturbed subsoils and/or engineered fill appear suitable for support for the proposed
structure. The footings may be designed for a maximum net allowable bearing pressure of 3,000 psf.
In addition, the footings should be sized to maintain a minimum dead-load pressure of 1,000 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. Interior footings in heated areas should be placed a
minimum of 18 inches below finished grade. 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 settlement is recommended; however, proportioning to relative constant dead-load
pressure will also reduce differential settlement between adjacent footings. Total settlement resulting
from the assumed structural loads is estimated to be on the order of 1 inch or less. 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 should be reinforced as necessary to reduce the potential for distress caused by
differential foundation movement. Foundation excavations should be observed by the geotechnical

' engineer. If the soil conditions encountered differ significantly from those presented in this report,
supplemental recommendations will be required.
Basement Construction
' Groundwater was encountered on the site at depths of 24 feet. Therefore, full-depth basement
construction is considered acceptable on the site.
' To reduce the potential for surface water to impact foundation bearing soils and enter the basement of
the structure, installation of a perimeter drainage system is recommended. The drainage system
should be constructed around the exterior perimeter of the basement foundation, and sloped at a
' minimum 1/8 inch per foot to a suitable outlet, such as a sump and pump system.
The drainage system should consist of a properly sized perforated pipe, embedded in free-draining
gravel, placed in a trench at least 12 inches in width. Gravel should extend a minimum of 3 inches
beneath the bottom of the pipe, and at least 2 feet above the bottom of the foundation wall. The gravel
' should be covered with drainage fabric prior to placement of foundation backfill.
Lateral Earth Pressures
For soils above any free water surface, recommended equivalent fluid pressures for unrestrained
foundation elements are:
' • Active:
Cohesionless soil backfill (on-site sand) 45 psf/ft
' On-site claystone materials not recommended for use
• Passive:
Cohesionless soil backfill (on-site sand) 300 psf/ft
Undisturbed soils or bedrock 350 psf/ft
• Coefficient of base friction 0.35*
' *The coefficient of base friction should be reduced to 0.30 when used in conjunction
with passive pressure.
Where the design includes restrained elements, the following equivalent fluid pressures are
recommended:

Terracon Project No. 21035059 Terracon
• At rest:
Cohesionless soil backfill (on-site sand) 60 psf/ft
On-site claystone materials not recommended for use
The lateral earth pressures herein do not include any factor of safety and are not applicable for
' submerged soils/hydrostatic loading. Additional recommendations may be necessary if submerged
conditions are to be included in the design.
Fill against grade beams and retaining walls should be compacted to densities specified in Earthwork.
Claystone materials should not be used as backfill against basement walls. Compaction of each lift
' adjacent to walls should be accomplished with hand-operated tampers or other lightweight
compactors. Overcompaction may cause excessive lateral earth pressures which could result in wall
movement.
' Seismic Considerations
The project site is located in Seismic Risk Zone I of the Seismic Zone Map of the United States as
indicated by the 1997 Uniform Building Code. Based upon the nature of the subsurface materials, a
soil profile type Sc should be used for the design of structures for the proposed project (1997 Uniform
Building Code, Table No. 16-J).
Floor Slab Design and Construction
' The variability of the existing soils at approximate slab subgrade elevation could result in differential
' movement of floor slab-on-grade should expansive soils become elevated in moisture content.
Differential slab movement on the order of about 1 inch is possible for slabs bearing within 3 feet. Use
of structural floor systems, structurally supported independent of the subgrade soils, is a positive
' means of eliminating the potentially detrimental effects of floor movement.
If slab-on-grade is utilized, the subgrade soils should be prepared as outlined in the earthwork section
1 of this report. A common practice to reduce potential slab heave involves overexcavation of the
expansive soils and replacing these materials with non-expansive imported fill. This alternative will not
eliminate the possibility of slab heave; but movements should be reduced and tend to be more
' uniform.
' 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.

Terracon Project No. 21035059 Terracon
• Control joints should be provided in slabs to control the location and extent of
' cracking.
• A minimum 2-inch void space should be constructed above, or below non-bearing
partition walls placed on the floor slab. Special framing details should be provided at
door jambs and frames within partition walls to avoid potential distortion. Partition
walls should be isolated from suspended ceilings.
• Interior trench backfill placed beneath slabs should be compacted in accordance with
recommended specifications outlined below.
• Floor slabs should not be constructed on frozen subgrade.
' • Other design and construction considerations, as outlined in the ACI Design Manual,
' Section 302.1R are recommended.
Septic System Construction
Field test results indicate that a standard septic system and leach field (soil absorption bed) is feasible
for construction on the site. The system should be designed in accordance with applicable state and
county requirements and should be located at the minimum distances from all pertinent ground
features described in Weld County regulations. An average percolation rate of 15 minutes per inch is
recommended for design purposes.
Sandstone bedrock was a ountered in the soil profile boring, located at the proposed soil absorption
bed, at a depth of 3 fe t. li is our opinion that the sandstone bedrock encountered does not constitute
' a limiting zone or layer Accordingly, the bottom of the leach field should not be constructed below a
depth of 4 feet from existing site grade.
Additional design criteria for septic system construction are as follows:
• Based upon the proposed residence containing 3 bedrooms, the proposed soil
absorption bed should include a minimum of 780 square feet in plan view.
t • A minimum 1,000-gallon capacity septic tank should be used in the design and
construction.

• Distribution lines within the soil absorption bed should consist of 3- or 4-inch diameter
perforated plastic or similar pipe approved in governing regulations. Distribution lines
t should be placed the full length of the proposed absorption bed or trench and should
not exceed 100-feet in length. Distribution lines should be spaced at a maximum of 6
feet on center with the perimeter lines placed within 3 feet of all sides in the
' absorption bed.
' • Absorption beds should be backfilled with a minimum 12 inch thickness of clean
graded gravel ranging in size from 3/4 to 2-1/2 inches in diameter. The gravel should
6 inches below and 2 inches above the distribution pipes.
• The
extend gravelaminimum bed shouldof be completely covered with untreated building paper prior to
final soil cover. Final soil cover should be a minimum of 12 inches in thickness and
' suitable for vegetative growth. The surface of the soil cover should be graded for
positive surface drainage and to reduce the possibility of surface water infiltration.
' • A gravelless soil absorption bed, or infiltrator system, may also be considered as an
alternative to the standard type gravel system outlined above. Terracon understands
Weld County allows for a 50% reduction of the leach field size for infiltrator systems.
Accordingly, the infiltrator system should consist of a minimum of 26 chambers with
infiltrator rows spaced at a minimum spacing of 3%feet on center.
' Earthwork
' General Considerations
The following presents recommendations for site preparation, excavation, subgrade preparation and
Iplacement of engineered fills on the project.
All earthwork on the project should be observed and evaluated by Terracon. 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.

Terracon Project No. 21035059 Terracon
Site Preparation
Strip and remove existing vegetation, debris, and other deleterious materials from proposed building
areas. Stripped materials consisting of vegetation and organic materials should be wasted from the
site.
' Subgrade soils beneath proposed interior and exterior slabs, as well as all exposed areas which will
receive fill, once properly cleared where necessary, should be scarified to a minimum depth of 8
inches, conditioned to near optimum moisture content, and compacted.
Although evidence of fills or underground facilities such as septic tanks, cesspools, basements, and
utilities was not observed during the site reconnaissance, such features could be encountered during
construction. 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.
Excavations penetrating the bedrock may require the use of specialized heavy-duty equipment, such
as a track hoe, to facilitate rock break-up and removal.
Based upon the subsurface conditions determined from the geotechnical exploration, subgrade soils
exposed during construction are anticipated to be relatively stable. However, 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. Overexcavation of wet
tzones and replacement with granular materials may be necessary.
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
' Clean on-site soils void of claystone or approved imported materials may be used as fill material.
Imported soils (if required) should conform to the following:

' 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 is 95% of maximum dry density as determined by the
standard Proctor method ASTM D698.
On-site and imported sand soils should be compacted within a moisture range of 4 percent below to 2
' percent above optimum unless modified by the project geotechnical engineer.
Excavation and Trench Construction
Excavations into the on-site soils will encounter a variety of conditions, including caving soils. 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.
The soils to be penetrated by the proposed excavations may vary significantly across the site. The
preliminary soil classifications 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.
As a safety measure, it is recommended that all vehicles and soil piles be kept to a minimum lateral
distance from the crest of the slope equal to no less than the slope height. The exposed slope face
should be protected against the elements.

' Additional Design and Construction Considerations
' Underground Utility Systems
All piping should be adequately bedded for proper load distribution. It is suggested that clean, graded
gravel compacted to 75 percent of Relative Density ASTM D4253 be used as bedding. Utility trenches
should be excavated on safe and stable slopes in accordance with OSHA regulations as discussed
above. Backfill should consist of the on-site soils or existing bedrock void of claystone. If bedrock is
' used, all plus 6-inch material should be removed from it prior to its use. Claystone materials should
not be placed in structural areas such as beneath slabs or foudations. The pipe backfill should be
compacted to a minimum of 95 percent of Standard Proctor Density ASTM D698.
' All underground piping within or near the proposed structure should be designed with flexible
couplings, so minor deviations in alignment do not result in breakage or distress. Utility knockouts in
1 grade beams should be oversized to accommodate differential movements.
' Surface Drainage
Positive drainage should be provided during construction and maintained throughout the life of the
' proposed residence. 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 residence should be sealed or eliminated. In areas where slabs do not immediately adjoin the
' residence, we recommend that protective slopes be provided with a minimum grade of approximately
10 percent for at least 10 feet from perimeter walls. Backfill 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. Sprinkler systems should not
be installed within 5 feet of foundation walls. Landscaped irrigation adjacent to the foundation system
' should be minimized or eliminated.
GENERAL COMMENTS
1 Terracon should be retained to review the final design plans and specifications so comments can be
made regarding interpretation and implementation of our geotechnical recommendations in the
design and specifications. Terracon also should be retained to provide testing and observation
during excavation, grading, foundation and construction phases of the project.

Water levels indicated on the boring logs are the levels measured in the borings at the times indicated. Groundwater levels at other
times and other locations across the site could vary. In pervious soils,the indicated levels may reflect the location of groundwater. In
low permeability soils,the accurate determination of groundwater levels may not be possible with only short-term observations.
IDESCRIPTIVE SOIL CLASSIFICATION: Soil classification is based on the Unified Classification System. Coarse Grained Soils have
more than 50% of their dry weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand. Fine
I Grained Soils have less than 50% of their dry weight retained on a #200 sieve; they are principally described as clays if they are
plastic,and silts if they are slightly plastic or non-plastic. Major constituents may be added as modifiers and minor constituents may be
added according to the relative proportions based on grain size. In addition to gradation,coarse-grained soils are defined on the basis
of their in-place relative density and fine-grained soils on the basis of their consistency.

GENERAL NOTES
ISedimentary Rock Classification
bESCRIPTIVE ROCK CLASSIFICATION:
Sedimentary rocks are composed of cemented clay, silt and sand sized particles.The most
I common minerals are clay, quartz and calcite. Rock composed primarily of calcite is called
limestone; rock of sand size grains is called sandstone,and rock of clay and silt size grains
is called mudstone or claystone,siltstone,or shale. Modifiers such as shaly,sandy,dolomitic,
I
calcareous,carbonaceous,etc.are used to describe various constituents.Examples: sandy
shale; calcareous sandstone.
LIMESTONE Light to dark colored,crystalline to fine-grained texture, composed of CaCo,, reacts readily
with HCI.
I DOLOMITE Light to dark colored, crystalline to fine-grained texture, composed of CaMg(CO,),, harder
than limestone, reacts with HCI when powdered.
CHERT Light to dark colored,very fine-grained texture,composed of micro-crystalline quartz(Si0,),
I SHALE brittle, breaks into angular fragments, will scratch glass.
Very fine-grained texture, composed of consolidated silt or clay, bedded in thin layers.The
unlaminated equivalent is frequently referred to as siltstone, claystone or mudstone.
SANDSTONE Usually light colored,coarse to fine texture,composed of cemented sand size grains of quartz,
I
feldspar,etc.Cement usually is silica but may be such minerals as calcite,iron-oxide,or some
other carbonate.
CONGLOMERATE Rounded rock fragments of variable mineralogy varying in size from near sand to boulder size
I but usually pebble to cobble size(1/2 inch to 6 inches).Cemented together with various cemen-
ting agents. Breccia is similar but composed of angular, fractured rock particles cemented
together.
