Subject: Subsoil Study for Foundation Design and Percolation Test, Proposed
Residence, Lot 19, Stirling Ranch, Garfield County, Colorado
Dear Ms. Harris
As requested, Hepworth-Pawlak Geotechnical, Inc. perfoi,7fred a subsoil study and
percolation test for foundation and septic disposal designs at the subject site. The study
was conducted in accordance with our agreement for geotechnical engineering services to
you dated August 30, 2007. The data obtained and our recommendations based on the
proposed construction and subsurface conditions encountered are presented in this report.
Proposed Construction: The proposed residence will be a two story wood frame
structure above a partial walkout basement and partial crawlspace and located on the site
as shown on Figure 1. Basement and garage floors are proposed to be slab -on -grade. Cut
depths are expected to range between about 2 to 8 feet. Foundation loadings for this type
of construction are assumed to be relatively light and typical of the proposed type of
construction. The septic disposal system is proposed to be located downhill and south of
the residence.
If building conditions or foundation loadings are significantly different from those
described above, we should be notified to re-evaluate the recommendations presented in
this report.
Site Conditions: The site is located on Clipper Place and is vacant of structures.
Vegetation consists of sage brush, juniper trees and grass with weeds. The building site is
located on a topographic knob and slopes moderately down at grades of about 10 to 15
percent. Scattered basalt cobbles and boulders are visible on the ground surface.
Subsurface Conditions: The subsurface conditions at the site were evaluated by
excavating two exploratory pits in the building area and one profile pit in the septic
Parker 303-841-7119 e Colorado Springs 719-633.5562 Silvert.horne 970-468-1989
_2 -
disposal area at the approximate locations shown on Figure 1. The logs of the pits are
presented on Figure 2. The subsoils encountered, below about 1 to 2'/2 feet of topsoil,
consist of basalt cobbles and boulders in a clayey silt and sand matrix. Results of swell -
consolidation testing performed on relatively undisturbed samples of silt and sand matrix
soils, presented on Figure 3, indicate low compressibility under existing moisture
conditions and light loading and a low collapse potential when wetted and under
additional loading. Results of gradation analysis performed on samples of silty sandy
gravel with cobbles (minus 5 inch fraction) obtained from the site are presented on Figure
4. The laboratory test results are summarized in Table 1. No free water was observed in
the pits at the time of excavation and the soils were slightly moist to moist.
Foundation Recommendations: Considering the subsoil conditions encountered in the
exploratory pits and the nature of the proposed construction, we recommend spread
footings placed on the undisturbed natural soil, below topsoil, designed for an allowable
soil bearing pressure of 2,000 psf for support of the proposed residence. Footings should
be a minimum width of 16 inches for continuous walls and 2 feet for columns. Utility
trenches and deep cut areas below about 3 feet may require rock excavating techniques
such as chipping or blasting. Loose and disturbed soils encountered at the foundation
bearing level within the excavation should be removed and the footing bearing level
extended down to the undisturbed natural soils. Voids created from boulder removal at
footing grade should be filled with a structural material such as road base compacted to
98 percent standard Proctor density at a moisture content near optimum or concrete.
Exterior footings should be provided with adequate cover above their bearing elevations
for frost protection. Placement of footings at least 36 inches below the exterior grade is
typically used in this area. Continuous foundation walls should be reinforced top and
bottom to span local anomalies such as by assuming an unsupported length of at least 12
feet. Foundation walls acting as retaining structures should be designed to resist a lateral
earth pressure based on an equivalent fluid unit weight of at least 50 pcf for the on-site
soil as backfill.
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
Job No.107 0667
tZtech
-3 -
basement level slabs to facilitate drainage. This material should consist of minus 2 inch
aggregate with less than 50% passing the No. 4 sieve and less than 2% passing the No.
200 sieve.
Ali 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 soils devoid of vegetation, topsoil and oversized rock.
Underdrain System: Although free water was not encountered during our exploration, it
has been our experience in the area that local perched groundwater can develop during
times of heavy precipitation or seasonal runoff Frozen ground during spring runoff can
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. The drain should
be placed at each level of excavation and at least 1 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 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 11/a feet deep.
Surface Drainage: The following drainage precautions should be observed during
construction and maintained at all times after the residence has 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. Free -draining wall backfill should be
capped with about 2 feet of the on-site, finer graded soils to reduce surface
water infiltration.
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
Job No.107 0667
Gtech
-4 -
areas and a minimum slope of 3 inches in the first 10 feet in pavement and
walkway areas.
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 the building. Consideration should be given to the use
of xeriscape to limit potential wetting of soils below the building caused
by irrigation.
Percolation Testing: Percolation tests were conducted on November 21, 2007 to
evaluate the feasibility of an infiltration septic disposal system at the site. One profile pit
and three percolation holes were dug at the locations shown on Figure 1. The test holes
(nominal 12 inch diameter by 12 inch deep) were hand dug and soaked with water one
day prior to testing. The soils exposed in the percolation holes are similar to those
exposed in the Profile Pit shown on Figure 2 and consist of 1V2 feet of topsoil overlying
basalt cobbles and boulders in a sand and silt matrix. Results of gradation and
hydrometer analysis performed on a sample of slightly clayey silty sandy gravel with
cobbles (minus 5 inch fraction) obtained from the Percolation Test Hole 3 are presented
on Figure 5. The percolation test results are presented in Table 2. Based on the
subsurface conditions encountered and the percolation test results, the tested area should
be suitable for a conventional on-site waste disposal system. We recommend the
infiltration area be oversized due to the relatively slow percolation rate. A professional
engineer or county health department should design the on-site waste 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 expressed or implied. The conclusions and recommendations submitted
in this report are based upon the data obtained from the exploratory pits excavated 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 pits 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 at
once so re-evaluation of the recommendations may be made.

This report has been prepared for the exclusive use by our client for design purposes. We
are not responsible for technical interpretations by others of our information. As the
project evolves, we should provide continued consultation and field services during
construction to review and monitor the implementation of our recommendations, and to
verify that the recommendations have been appropriately interpreted. Significant design
changes may require additional analysis or modifications to the recommendations
presented herein. We recommend on-site observation of excavations and foundation
bearing strata and testing of structural fill by a representative of the geotechnical
engineer.
If you have any questions or if we may be of further assistance, please let us know.

Onsite Wastewater System Design. Proposed 4 -Bedroom Residence
Lor 19. Stirling Ranch. 232 Clipper Lane
Garfield County. Colorado
Josh.
Project No. 1534
.AL1.. SERVICE septic. 1.1.0 evaluated the subsurface investigation prepared by HP Geo -tech. Job No
107 0(567. and prepared an onsite wastewater system (O\ `S) design for the subject residence- The
property is located in Garfield County. in an area w%'here O\VS are necessary. This letter is to be used
in conjunction with report provided. The local water district provides water.
S1TF. CONDITION
A 4 -bedroom residence is proposed as indicated on Figure 1. The property is vacant. The residence
site is located on a topographic knob and slopes moderately down at grades of -about 10 to 1; percent.
The area of the proposed drain lied slopes to the southeast.
SUBSURFACE
'llic subsurface was investigated by HP Geo -tech by excavating one Profile Pit and three percolation
holes as indicated on attached plans. L11' Cleo -tech indicated the test has a 2 -foot topsoil layer. underlain
by basalt boulders, with a sandy silt matrix to the maximum depth explored of 10 feet. Groundwater
or bedrock was not encountered. Percolation rates ranged from 15 to 30 minutes per inch (MPI). A
20 \IPI rate will he used to design the OWS.
DESIGN SPECIFICATIONS
Based on recommendations Irish 11P Geotech, we have taken a 30' 5 reduction on drain field sizing
based on proposed grave€cess chamber trenches. The OWS design is bused on 4 -bedrooms and an
average sewage load of 600 CaP1). The installation must include a 1500 -gallon, two-compartment.
precast concrete septic tank. with the addition or an effluent filter in the second compartment. Tank
alteratives may be considered. Four grawvelless chamber trenches must he installed as indicated on
plans provided. Four rows of 15 'Quick 4' chambers, for a total of 60 chambers. and 593 square feet
(SF) of infiltrative area. is required. Serial distribution should be used to distribute effluent. The
.
trenches should be installed at a depth olapproxirnate.ly 2 -feet.

If a basalt boulder is encountered in thc trench excavation ii should be removed and onsite sand,: silty
soils placed in the void. Concrete sand may be used to fill thc void as an alternative.
Construction nu.ist be according to the county ISDS regulations. the septic permit provided by Garfield
County F..nvironmental Health Depaartntcnt. and this design. This desian for the subject property. noted
above. is valid only in conjunction with the approved County Health Department permit.
OPERATION 1NFORM.ATION AND MAINTENANCE
The surface of the drain field should be seeded upon completion. Vegetation is an important factor in
drain field performance. Erosion control should he practiced during and prior to re -vegetation. Geo -
fabrics or plastics should not be used over the drain tiie.lcl. No heavy equipment. machinery. or
materials should be placed on hacktilled dram field. Livestock estock should not graze on the drain field.
Plumbing Fixtures should be checked to ensure that no additional tater is being discharged to OWS.
For Example_ a running toilet or leak' faucet can discharge hundreds of gallons of water a day and
ham a drain field.
The homeowner should pump the septic tank every two years and clean the effluent filter as needed.
Garbage disposal use should be minimized. and non -biodegradable materials should not be placed
into the OWS. Cirease should not be placed in household drains. Loading adinRg from a 'Fater softener
should not he discharged into the OWS. No hazardous wastes should be directed into the OWS.
yleehanical room drains should not discharge into the OWS. The OWS is engineered for domestic.
waste only.
ADDITIONAL CONS'T'RUCTION NOTES
If design includes a pump. air release valves and weep holes should be installed to allow pump tines
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 he placed on all septic tank components
to alloy+ access to them from existing grade. Precast concrete tanks and distribution boxes should he
used. unless plastic or fiberglass is required. Septic tank risers should extend to grade. Access to all
tank compartments and distribution devices is optimal.
INSTALLATION OBSERVATIONS
.AI.,I, SERVICE septic. L.LC. and the county must view the ()\V5 during construction. The t)\\'S
observation should he performed before backfill, after placement of chambers and distribution pipes.
Septic tanks. distribution devices. pumps. dosing siphons. and rafter plumbing. as applicable. must
also be observed. All: SERVICE septic. l..I.0 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 he notified. All OWS construction
must be according to the county regulations. Requirements not specified in this report must follow
county reraulations. 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.
