Onsite Wastewater Treatment System (OWTS) Installation Observations
Roth Residence
1153 &1155 South Starwood Drive
Tract R-55 Starwood
Pitkin County, Colorado
OWTS Construction Permit 0026.2013.powt
Tony,
Project No. C1021
ALL SERVICE septic, LLC observed the installation of the onsite wastewater treatment system (OWTS)
on June 17, 2014 for the subject property. Aspen Earthmoving installed the system. The OWTS was
installed in accordance with ALL SERVICE septic, LLC design dated August 20, 2013.
The installation included a new 1500 -gallon, two-compartment Valley Precast concrete septic tank with
an Orenco® Biotube Effluent Filter on the outlet tee to serve the Main House. The sewer line from the
1500 -gallon septic tank ties into a new 1000 -gallon, two-compartment Valley Precast concrete septic tank
with a screened dosing siphon in the second compartment that serves the Caretaker Dwelling Unit
(CDU). Both the Orenco® Biotube Effluent Filter in the septic tank serving the Main House and
the screen surrounding the dosing siphon in the septic tank serving the CDU must be cleaned
annually, or as needed.
The original design specified a pump; however, sufficient fall was able to be obtained to utilize a
dosing siphon.
Effluent is dosed to a distribution box, and then gravity flows to five rows of 23 `Quick 4' Infiltrator®
chambers for a total of 1135 square feet of infiltrative area (using 9.87 square feet per chamber). There
was a minimum of 6 -feet of undisturbed soil between each trench. Inspection ports were installed at the
end of each trench.
The OWTS was generally installed according to specifications. This observation is not a guarantee of
workmanship and/or parts and materials. ALL SERVICE septic, LLC should be notified if changes are
made to the O`JVTS in the future. Any additional OWTS construction must be according to the county
regulations.
LIMITS:
Observations are limited to components that are visible at the time of the inspection. The installer must
have documented and demonstrated knowledge of the requirements and regulations of the county in
which they are working. The quality of the installation is dependent of the expertise of the installer, soil
type, and weather conditions.
Please call with questions.
Sincerely,
ALL SERVICE septic, LLC

Onsite Wastewater Treatment System Design
Tract R-55 Starwood
Pitkin County, Colorado
Tony,
Project No. C1021
ALL SERVICE septic, LLC performed has designed an onsite wastewater treatment system (OWTS)
design for the subject property to serve two proposed residences. The property is located outside of
Aspen, in an area where OWTSs are necessary. Domestic water will be supplied to the residences by
a public water system. The original design dated February 11, 2013 should be discarded.
SITE CONDITIONS
The property is currently vacant. Two residences are proposed; one main house with greater than
6000 square feet of living area and 4 -bedrooms, and a guest house with one bedroom. A report
prepared by HP Geotech dated December 31, 2012, Job #112 425A, describes the lot as northwest
facing with a strongly sloping to moderately steep natural ground surface. Vegetation consists of
aspen stands, grass, weeds, and brush. There are two active irrigation ditches located on the south and
west sides of the lot.
SUBSURFACE
The subsurface investigation was performed by HP Geotech on November 29, 2012. One profile hole
and three percolation holes were drilled. Results are detailed in the above mentioned HP Geotech report.
An average of 30 minutes per inch (MPI) will be used to design the OWTS.
DESIGN SPECIFICATIONS
The OWTS design is based on 4 -bedrooms in the main residence with greater than 6000 square feet
of living area and 1 -bedroom in the guest house. An average daily wastewater flow of 950 GPD will
be used. The installation must include a 1500 -gallon, two-compartment septic tank to serve the main
house. The main house tank will be connected to the inlet side of the 1000 -gallon, two-compartment
tank which will serve the guest house. A Biotube® pump vault will be installed in the second
compartment of the 1000 -gallon tank. An Orenco® PF3005 pump will dose effluent to a distribution
box, which will distribute effluent to five rows of 23 Quick4 Infiltrator® chambers.
0 0
Page 2
The trenches may be placed at the base of the grading for the driveway, with each trench following
the natural contours. Angle pieces can be used to better follow the contours and keep the depth of
trench burial between 2' and 4' over chambers.
The component manufacturers are typical of applications used by contractors and engineers in this
area. Alternatives may be considered or recommended by contacting our office. Construction must
be according to Pitkin County Onsite Wastewater Treatment System Regulations, the OWTS
Construction Permit provided by Pitkin County Environmental Health Department, and this design.
REVEGETATION REQUIREMENTS
An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the
entire disturbed are of the OWTS installation. A mixture of native grass seed that has good soil
stabilizing characteristics (but without taproots), provides a maximum transpiration rate, and competes
well with successional species. No trees or shrubs, or any vegetation requiring regular irritation shall be
plated over the area. Until vegetation is reestablished, erosion and sediment control measures shall be
implemented and maintained on site. The owner of the OWTS shall be responsible for maintaining
proper vegetation cover.
OPERATION INFORMATION AND MAINTENANCE
The property owner shall be responsible for the operation and maintenance of each OWTS servicing the
property. The property owner is responsible for maintaining service contracts for manufactured units,
alternating absorption systems, and any other components needing maintenance.
Geo -fabrics or plastics should not be used over the absorption area. No heavy equipment, machinery, or
materials should be placed on backfilled absorption area. Livestock should not graze on the absorption
area. Plumbing fixtures should be checked to ensure that no additional water is being discharged to
OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day
and harm an absorption area.
The homeowner should pump the septic tank every two years, or as needed gauged by measurement of
solids in the tank. Garbage disposal use should be minimized, and non -biodegradable materials should
not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water
softener should not be discharged into the OWTS. No hazardous wastes should be directed into the
OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for
domestic waste only.
ADDITIONAL CONSTRUCTION NOTES
If design includes a pump, air release valves and weep holes should be installed to allow pump lines
to drain to minimize risk of freezing. Excavation equipment must not drive in excavation of the
absorption area due to the potential to compact soil. Extensions should be placed on all septic tank
components to allow access to them from existing grade.
J
Page 3
INSTALLATION OBSERVATIONS
ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation
should be performed before backfill, after placement of OWTS components. Septic tanks, distribution
devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL
SERVICE septic, LLC should be notified 48 hours in advance to observe the installation.
LIMITS:
The design is based on information submitted. If soil conditions encountered are different from
conditions described in report, ALL SERVICE septic, LLC should be notified. All OWTS
construction must be according to the county regulations. Requirements not specified in this report
must follow applicable county regulations. The installer should have documented and demonstrated
knowledge of the requirements and regulations of the county in which they are working.
Please call with questions.
Sincerely,

PURPOSE AND SCOPE OF STUDY
This report presents the results of a subsoil study for a proposed residence to be located
on Lot R-55, Starwood Subdivision, South Starwood Drive, Pitkin County, Colorado.
The project site is shown on Figure 1. The purpose of the study was to develop
recommendations for the foundation and septic disposal design. The study was
conducted in accordance with our proposal for geotechnical engineering services to Larry
Roth dated November 20, 2012.
A field exploration program consisting of exploratory borings was conducted to obtain
information on the subsurface conditions. Samples of the subsoils obtained during the
field exploration were tested in the laboratory to determine their classification,
compressibility or swell and other engineering characteristics. The results of the field
exploration and laboratory testing were analyzed to develop recommendations for
foundation types, depths and allowable pressures for the proposed building foundation.
This report summarizes the data obtained during this study and presents our conclusions,
design recommendations and other geotechnical engineering considerations based on the
proposed construction and the subsurface conditions encountered.
PROPOSED CONSTRUCTION
The proposed construction will consist of a two story main residence over a walk -out
basement level with an attached garage and a single story CDU over walk -out basement
level, located on the lot as shown on Figure 1. The basement levels will be slab -on -grade
and a portion of the main residence will be structurally supported over a erawlspaee level.
Grading for the structure is assumed to be relatively minor with cut depths between about
4 to 10 feet. We assume relatively light foundation Ioadings, typical of the proposed type
of construction.
If building loadings, location or grading plans change significantly from those described
above, we should be notified to re-evaluate the recommendations contained in this report.

SITE CONDITIONS
The lot was vacant at the time of our field exploration. The lot is located on a northwest -
west facing hillside with a strongly sloping to moderately steep natural ground surface
down to the northwest. Vegetation consists of dense aspen stands, grass, weeds and
brush. Active irrigation ditches are located on the southeast and west sides of the lot.
FIELD EXPLORATION
The field exploration for the project was conducted on November 28, 2012. Two
exploratory borings were drilled at the locations shown on Figure 1 to evaluate the
subsurface conditions. The borings were advanced with 4 inch diameter continuous flight
augers powered by a truck -mounted CME -45B drill rig. The borings were logged by a
representative of Hepworth-Pawlak Geotechnical, Inc.
Samples of the subsoils were taken with a 2 inch I.D. spoon sampler. The sampler was
driven into the subsoils at various depths with blows from a 140 pound hammer falling 30
inches. This test is similar to the standard penetration test described by ASTM Method
D-1586. The penetration resistance values are an indication of the relative density or
consistency of the subsoils. Depths at which the samples were taken and the penetration
resistance values are shown on the Logs of Exploratory Borings, Figure 2. The samples
were returned to our laboratory for review by the project engineer and testing.
SUBSURFACE CONDITIONS
Grapaic logs of the subsurface conditions encountered at the site are shown on Figure 2.
The subsoils consist of about 1 foot of topsoil overlying very stiff to hard, slightly
gravelly, sandy, silty clay with clayey silty sand and sandy silt lenses.
Laboratory testing performed on samples obtained from the borings included natural
moisture content, density, finer than sand size gradation analyses and liquid and plastic

limits. Results of swell -consolidation testing performed on relatively undisturbed drive
samples of the natural clay soils, presented on Figures 4 and 5, indicate low to moderate
compressibility under conditions of loading and wetting and minor swell or collapse
potential (settlement under constant load) when wetted under constant light surcharge
loading. The laboratory testing is summarized in Table 1.
No free water was encountered in the borings at the time of drilling or when checked I
day later and the subsoils were slightly moist to moist.
FOUNDATION BEARING CONDITIONS
The sandy silty clay soils encountered in the borings typically possess a low bearing
capacity and low settlement/heave potential if wetted. Spreading footing bearing on the
natural fine-grained soils can be used provided the risk of potential differential movement
is acceptable to the owner. We should further evaluate the bearing conditions and
settlement/heave potential at the time of construction.
DESIGN RECOMMENDATIONS
FOUNDATIONS
The design and construction criteria presented below should be observed for a spread
footing foundation system.
I) Footings placed on the undisturbed natural granular soils should be
designed for an allowable bearing pressure of 2,000 psf. Based on
experience, we expect settlement of footings designed and constructed as
discussed in this section will be about 1 inch. Additional movement could
occur if the bearing soils become wet. The amount of movement would
depend on the depth and extent of wetting. For a wetted depth of 10 feet
the additional movement could be up to I inch. Care should be taken to
Job No. 112 425A G8'ftech
M
reduce the risk of subsurface wetting by following the recommendations
contained in this report
2) The footings should have a minimum width of 16 inches for continuous
walls and 2 feet for isolated pads.
3) Exterior footings and footings beneath unheated areas should be provided.
with adequate soil cover above their bearing elevation for frost protection.
Placement of foundations at least 42 inches below exterior grade is
typically used in this area.
4) Continuous foundation walls should be reinforced top and bottom to span
local anomalies. Foundation walls acting as retaining structures should
also be designed to resist lateral earth pressures as discussed in the
"Foundation and Retaining Walls" section of this report.
5) Existing topsoil and any loose or disturbed soils should be removed and
the footing bearing level extended down to the undisturbed natural clay
soils. The exposed soils in footing area should then be moistened and
compacted.
6) A representative of the geotechnical engineer should observe all footing
excavations prior to concrete placement to evaluate bearing conditions.
FOUNDATION AND RETAINING WALLS
Foundation walls and retaining structures which are laterally supported and can be
expected to undergo only a slight amount of deflection should be designed for a lateral
earth pressure computed on the basis of an equivalent fluid unit weight of at least 55 pcf
for backfill consisting of the on-site fine-grained soils. Cantilevered retaining structures
which are separate from the residences and can be expected to deflect sufficiently to
mobilize the full active earth pressure condition should be designed for a lateral earth
pressure computed on the basis of an equivalent fluid unit weight of at least 45 pcf for
backfill consisting of the on-site fine-grained soils.
Job No. 112425A G-�'Oftech
-5 -
All foundation and retaining structures should be designed for appropriate hydrostatic and
surcharge pressures such as adjacent footings, traffic, construction materials and
equipment. The pressures recommended above assume drained conditions behind the
walls and a horizontal backfill surface. The buildup of water behind a wall or an upward
sloping backfill surface will increase the lateral pressure imposed on a foundation wall or
retaining structure. An underdrain should be provided to prevent hydrostatic pressure
buildup behind walls.
Backfill should be placed in uniform lifts and compacted to at least 90% of the maximum
standard Proctor density at a moisture content near optimum. Backfill in pavement and
walkway areas should be compacted to at least 95% of the maximum standard Proctor
density. Care should be taken not to overcompact the backfill or use large equipment
near the wall, since this could cause excessive lateral pressure on the wall. Some
settlement of deep foundation wall backfill should be expected, even if the material is
placed correctly, and could result in distress to facilities constructed on the backfill.
The lateral resistance of foundation or retaining wall footings will. be a combination of the
sliding resistance of the footing on the foundation materials and passive earth pressure
against the side of the footing. Resistance to sliding at the bottoms of the footings can be
calculated based on a coefficient of friction of 0.35. Passive pressure of compacted
backfill against the sides of the footings can be calculated using an equivalent fluid unit
weight of 350 pc£ The coefficient of friction and passive pressure values recommended
above assume ultimate soil strength. Suitable factors of safety should be included in the
design to limit the strain which will occur at the ultimate strength, particularly in the case
of passive resistance. Fill placed against the sides of the footings to resist lateral loads
should be compacted to at least 95% of the maximum standard Proctor density at a
moisture content near optimum.
Job No. 112 425A GLCPf@Cl 1
-6 -
FLOOR SLABS
The natural on-site soils, exclusive of topsoil, are suitable to support lightly loaded slab -
on -grade construction. To reduce the effects of some differential movement, floor slabs
should be separated from all bearing walls and columns with expansion joints which
allow unrestrained vertical movement. Floor slab control joints should be used to reduce
damage due to shrinkage cracking. The requirements for joint spacing and slab
reinforcement should be established by the designer based on experience and the intended
slab use. A minimum 4 inch layer of free -draining gravel should be placed beneath
basement level slabs to facilitate drainage. This material should consist of minus 2 inch
aggregate with at least 50% retained on the No. 4 sieve and less than 2% passing the No.
200 sieve.
All fill materials for support of floor slabs should be compacted to at least 95% of
maximum standard Proctor density at a moisture content near optimum. Required fill can
consist of the on-site granular soils devoid of vegetation, topsoil and oversized rock.
UN13ERDRAIN SYSTEM
Although free water was not encountered during our exploration, it has been our
experience in mountainous areas that local perched groundwater can develop during times
of heavy precipitation or seasonal runoff. Frozen ground during spring runoff can also
create a perched condition. We recommend below -grade construction, such as retaining
walls, crawlspace and basement areas, be protected from wetting and hydrostatic pressure
buildup by an underdrain system.
The drains should consist of drainpipe placed in the bottom of the wall backfill
surrounded above the invert level with free -draining granular material wrapped in filter
fabric. The drain should be placed at each level of excavation and at least I foot below
lowest adjacent finish grade and sloped at a minimum 1 % to a suitable gravity outlet.
Free -draining granular material used in the underdrain system.should contain less than
Job No. 112 425A � i
GecPtech
-7-
2% passing the No. 200 sieve, less than 50% passing the No. 4 sieve and have a
maximum size of 2 inches. The drain gravel backfill should be at least 1 % feet deep. An
impervious membrane such as 20 mil PVC should be placed beneath the drain gravel in a
trough shape and attached to the foundation wall with mastic to prevent wetting of the
bearing soils.
SURFACE DRAINAGE
The following drainage precautions should be observed during construction and
maintained at all times after the buildings have been completed:
1) Inundation of the foundation excavations and underslab areas should be
avoided during construction.
2) Exterior backfill should be adjusted to near optimum moisture and
compacted to at least 95% of the maximum standard Proctor density in
pavement and slab areas and to at least 90% of the maximum standard
Proctor density in landscape areas.
3) The ground surface surrounding the exterior of the building should be
sloped to drain away from the foundation in all directions. We
recommend a minimum slope of 12 inches in the first 10 feet in unpaved
areas and a minimum slope of 3 inches in the first 10 feet in paved areas.
Free -draining wall backfill should be capped with about 2 feet of the on-
site soils to reduce surface water infiltration. A swale may be needed
above the residence to direct surface runoff and irrigation ditch overflow
away from the residence. The irrigation ditch could be lined to reduce the
risk of ditch leakage impacting the house.
4) Roof downspouts and drains should discharge well beyond the limits of all
backfill.
5) Landscaping which requires regular heavy irrigation should be located at
least 10 feet from foundation walls. Consideration should be given to use
of xeriscape to reduce the potential for wetting of soils below the building
caused by irrigation.

PERCOLATION TESTING
Percolation tests were conducted on November 29, 2012 to evaluate the feasibility of an
infiltration septic disposal system at the site. One profile boring and three percolation
holes were drilled at locations as shown on Figure 1. The test holes were drilled with 6
inch diameter auger and were soaked with water one day prior to testing. The soils
encountered in the percolation holes are similar to those encountered in the Profile Hole
shown on Fig. 2 and consist of about 1 foot of topsoil overlying stiff to very stiff, sandy
silty clay. The percolation test results are presented in Table 2. A civil engineer should
design the infiltration septic disposal system.
LIMITATIONS
This study has been conducted in accordance with generally accepted geotechnical
engineering principles and practices in this area at this time. We make no warranty either
express or implied. The conclusions and recommendations submitted in this report are
based upon the data obtained from the exploratory borings drilled at the locations
indicated on Figure 1, the proposed type of construction and our experience in the area.
Our services do not include determining the presence, prevention or possibility of mold or
other biological contaminants (MOBC) developing in the future. If the client is
concerned about MOBC, then a professional in this special field of practice should be
consulted. Our findings include interpolation and extrapolation of the subsurface
conditions identified at the exploratory borings and variations in the subsurface
conditions may not become evident until excavation is performed. If conditions
encountered during construction appear different from those described in this report, we
should be notified so that re-evaluation of the recommendations may be made.

Onsite Wastewater Treatment Systen
Tract R-55 Starwood
Pitkin County, Colorado
Tony,
Project No. C 1021
ALL SERVICE septic, LLC performed has designed an onsite wastewater treatment system (OWTS)
design for the subject property to' rve two proposed residences. The property is located outside of
Aspen, in an area where OWTSs e necessary. Domestic water will be supplied to the residences by
a public water system. ��
The property is currentfely
wo re ' ences are proposed; one main house with less than 6000
square feet of living arrooms, d a guest house with one bedroom. A report prepare
by HP Geotech dated D 2012, Job 112 425A, describes the lot as northwest facing with a
strongly sloping to mop natural round surface. Vegetation consists of aspen stands,
grass, weeds, and brushwo active i igation ditches located on the south and west sides of
the lot.
_----- BSURFACE
The subsurface investigation was rformed by HP Geotech on November 29, 2012. One profile hole
and three percolation holes were drill Results are detailed in the above mentioned HP Geotech report.
An average of 30 minutes per inch (MPI) ill be used to design the OWTS.
SPECIFICATIONS
The OWTS design is based on 4 -bedrooms in the main residence with less than 6000 square feet of
living area and I -bedroom in the guest house. An average daily wastewater flow of 750 GPD will be
used. The installation must include a 1500 -gallon, two-compartment septic tank to serve the main
house. The main house tank will be connected to the inlet side of the 1000 -gallon, two-compartment
tank which will serve the guest house. A Biotube® pump vault will be installed in the second
compartment of the 1000 -gallon tank. An Orenco® P-30 pump will dose effluent to a distribution
box, which will distribute effluent to four rows of 23 Quick4 Infiltrator® chambers.
Page 2
The trenches may be placed at the base of the grading for the driveway, with each trench following
the natural contours. Angle pieces can be used to better follow the contours and keep the depth of
trench burial between 2' and 4' over chambers.
Construction must be according to Pitkin County Onsite Wastewater Treatment System Regulations, the
OWTS Construction Permit provided by Pitkin County Environmental Health Department, and this
design.
OPERATION INFORMATION AND MAINTENANCE
The property owner shall be responsible for the operation and maintenance of each OWTS servicing
the property. The property owner is responsible for maintaining service contracts for manufactured
units, alternating absorption systems, and any other components needing maintenance.
The surface of the drain field should be seeded upon completion. Vegetation is an important factor in
drain field performance. Erosion control should be practiced prior to and during re -vegetation. Geo -
fabrics or plastics should not be used over the drain field. No heavy equipment, machinery, or
materials should be placed on backfilled drain field. Livestock should not graze on the drain field.
Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS.
For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and
harm a drain field.
The homeowner should pump the septic tank every two years, or as needed gauged by measurement
of solids in the tank. Garbage disposal use should be minimized, and non -biodegradable materials
should not be placed into the OWTS. Grease should not be placed in household drains. Loading from
a water softener should not be discharged into the OWTS. No hazardous wastes should be directed
into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is
engineered for domestic waste only.
ADDITIONAL CONSTRUCTION NOTES
If design includes a pump, air release valves and weep holes should be installed to allow pump lines
to drain to minimize risk of freezing. Excavation equipment must not drive in excavation of drain
field due to the potential to compact soil. Extensions should be placed on all septic tank components
to allow access to them from existing grade. Precast concrete tanks and distribution boxes should be
used, unless plastic or fiberglass is required. Access to all tank compartments and distribution devices
is optimal.
INSTALLATION OBSERVATIONS
ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation
should be performed before backfill, after placement of OWTS components. Septic tanks, distribution
devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL
SERVICE septic, LLC should be notified 48 hours in advance to observe the installation.
LIMITS:
Page 3
The design is based on information submitted. If soil conditions encountered are different from
conditions described in report, ALL SERVICE septic, LLC should be notified. All OWTS
construction must be according to the county regulations. Requirements not specified in this report
must follow applicable county regulations. The installer should have documented and demonstrated
knowledge of the requirements and regulations of the county in which they are working.
Please call with questions.
Sincerely,
ALL SERVICE septic, LLC

RE: Water Service in Starwood Subdivision
This is to confirm that the Starwood Metropolitan District will
supply water to the residence on Tract R-55, 1115 South Starwood
Drive, Starwood Subdivision, Aspen, Colorado that is owned by
Laurence, Nanci and David Roth. Because the Starwood Metropolitan
District. supplies all water to the residence and property, it
does not, depend on a community well, and therefore, there is not
a community well agreement. The Starwood Metropolitan District
is an approved public water system and has sufficient water to
supply the development, which includes Tract R-55, and the
Starwood Metropolitan District agrees to do so.
If you have any questions, please call me at 970-925-8939 or
