Dear Ray:
On April 16, 2001, High, Country Engineering personnel observed the construction of the remedied
absorption trench for Lot 5-Oakridge 1, Aspen Mountain View Subdivision within Eagle County,
Colorado. The contractor had removed.nine (9) Infiltrator EQ-36 units and installed 12 new
standard Infiltrator units on top of 6+ inches of clean sand. With the installation of the sand, the
separation to bedrock should be greater than 4.0'. The provided absorption area is approximately
1,627 s.f. which exceeds the required absorption area of 1,500 s.f. An as -built drawing has also
been enclosed with this letter.

Awesome photos Deric! I noticed there is probably a need for risers in addition
to sealing around the inlets/outlets of the tank and maybe the Infiltrator
chambers? It would be nice to see the inside of the tank for the "T" location.
Did you see a soil profile? It is mentioned in Jordy's letter of April 27,1999
that an infiltration system would be feasible with the caveat that there is
adequate soil depth. There was no profile done near the leach field to verify a
suitable soil depth.
Let's remember that any changes to a permit need to be reviewed and approved by
my Division.
Who installed the system? It seems that there was confusion about this issue
and we became aware that an unlicensed person did the job. That's our issue and
not yours.
Thanks for your hard work on this system, it's been a difficult one!
Sincerely,
Ray

Ray,
I visited the Hodgson site yesterday to observe 3 profile pits that were
excavated around the constructed trench system. The following is a brief
description of each pit:
PP#1 (North side of field) 1.5-feet topsoil over sandy silt and clay.
Basalt fragments
depth
elevation as
approximately
found at a depth of 4.5-feet with backhoe refusal at a
of 6.5-feet. Top of pit at approximately same
top of cover of upper trench. Therefore,
4.25-feet of separation exists between backhoe refusal
depth and bottom of Infiltrator units
PP#2 (South side of field) 1.0-feet topsoil over sandy silt and clay.
Basalt fragments
found at a depth of 2.5-feet with backhoe refusal at a
depth
of 4.5-feet. Top of pit approximately 1.5-feet below
top of
cover of lowest trench. Therefore, approximately
3.75-feet
of separation between backhoe refusal depth and bottom
of Infiltrator units.
PP#3 (West side of field) 2.0-feet topsoil over sandy silt and clay. Basalt
fragments
depth
elevation as
approximately
found at a depth of 3.0-feet with backhoe refusal at a
of 6.25-feet. Top of pit at approximately same
top of cover of 2nd lowest trench. Therefore,
4.0-feet of separation exists between backhoe refusal
depth and bottom of Infiltrator units.
As you can see, the numbers are tight, but the general observation is that
separation has been maintained at or near 4-feet. The basalt rock layer
appears to slope to the south, away from the residence and adjacent owners.
The nearest well is located more than 250' away from the field and according
to the owner, was drilled to a depth of approximately 6001. Therefore,
contamination shouldn't be a concern.
Enclosed are photos of the site and profile pits. Please review these
photos and call me so that we may discuss this further.

subjt�ct: Subsoil Study for Foundation Design and Percolation Test, Proposed
Residence, Lot 5, Oak Ridge 1, Aspen Mountain View, Eagle County,
Colorado
Dear Mr, Jaworski:
As requested, Hepworth-Pawlak Gcoteehnical, Inc. performed a subsoil study and
perwlation test for foundation and septic disposal designs at the subject sill:, The study
was conducted in accordance with our agreement for geotechnical engineering services
to you dated 10 tM19. The data obtained and our recomnzendatiotis 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 over a garage and basement level. Ground floors are proposed to be slab-on-
gmde; Cut depths are expected to range between about 4 to 8 feet. Foundation
loadings for this type of construction are assumed to be relatively light and typical of
tho proposed type of construction. Tho septic disposal system is proposed to be located
ciownbill to the southwest of the proposed residence.
If building conditions or foundation loadings are significantly different from those
describcd above, we should be notified to re-evaluate the recommendations presented in
this report.
Site Conditions: The site was vacant at the time of our field work.. The ground
surface in the building area is gently rolling with a strong slope down to the south-
southwest, There about G feet of elevation difference across the proposed building area.
A gully is located near the southwest property corner. An irrigation ditch is located to
the northeast of the building envelope. The lot is vegetated with sagebrush, scruboak,
grass and weeds.

Subsurface Conditions: The subsurface conditions at the site were evaluated by
excavating two exploratory pits in the building area and t..........1�.p
disp&s6krea at the approximate locations shown on Fig. 1. The profile pits were
shallow due to -Fe ci '`Flnc logs of the pits are presented on Trig. 2.
The subsoils encountered, below consist of
cal r � tt 's It 1rty. Basalt fragments in a sandy clay matrix were
encountered beneath the topsoil in the profile pits. Results of swell -consolidation
testing performed on relatively undisturbed samples of the silt and clay, presented on
Fip. 3, indicate low to moderate compressibility under conditions of loading and
wetting. One sample :showed a low collapse potential (settlement under constant load)
when welted, The Iaboratory testing is surruniarized on Table I. 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
foothigs placed one the undisturbed natural soil designed for an allowable soil bearing
pressure of 1,500 psf for support of the proposed residence. The soils tend to compress
after vetting and there could be some post -construction foundation settlement. Footings
should be a ininimum width of 18 inches for continuous walls aitd 2 feet for columns,
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. Exterior footings should be provided with adequate cover
above tlicir nearing elevations for frost protection. placement of footings at least 42
inclhcs below the exterior grade is typically used in this area. Continuous foundation
'�,vFalis sliould 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
strucuires should be designed to resist a lateral earth pressure bascd on an equivalent
fluid unit weight of at least 50 pcf for the on -site soil as backfill.
il9lanor Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support
ligl,aly loaded slab -on -grade construction. The silt and clay soils are compressible when
wetted. To reduce the effects of some differential movement, floor slabs should be
separated from all bearing walls and columns with expansion joints which allow
wirestrained vertical movement. Floor slaty control joints should be used to reduce
darntage due to shrinkage cracking. The requirements for joint spacing and stab
reinforcement should be established by the designer based on experience and the
inicnded slab use. A mininium; 4 inch layer of free -draining gravel should be placed
bcocatln Naserncnt level slabs to facilitate drainage. This material should consist of

minus 2 inclr aggregate with less than 50% passing the No. 4 sieve and less than 2%
passing, the No. 200 sieve.
All 1-t11 materials for support of floor slabs should be compacted to at least 95% of
n3aaximum 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.
Ifuderdrain System: Although free water was not encountered during our exploration,
it bas bcen our experience in the area that local perched groundwater can develop
daring times of heavy Precipitation or seasonal runoff, Frozen, ground during spring
rtti)off can create a perched condition. We recommend below -grade construction, such
as retaining walls 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 backhll
surroundcd 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 /a to a suitable gravity outlet. Fret -draining
graaaxrlar 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 laolies, The drain gravel back -fill should be at least 11/2, feet deep. An impervious
nleinl)rane such as 20 mil PVC should be placed below the drain gravel in a trough
slope acid attacdted to the foundation wall with mastic to prevent wetting of the beariTtg
SOS,
S u Beat' Dr ain.,Ige: The following drainage precautions should be observed during
emistructlon and maintained at all times after the residence has been completed:
1) Inundation of the foundation excavations and unde;rslab areas should be
avoided during construction.
2) Exterior backf ll 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 surf ace; surrounding the exterior of the building should be
sloped to drain away from the foundation in all directions, We
recommend a miniiaium slope of 12 inches in the first 10 feet in unpaved.

areas and a nrtizlimum slope of 3 inches in the first 10 feet in pavement
and walkway areas. A Swale may be needed uphill to direct surface
runoff around the residence.
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 due to irrigation.
l er,colation Testing: Percolation tests were conducted on April 8, 1999 to evaluate tiie
feasibility of an infiltration septic disposal system at the site. Tvr i t«l>ree
locations shown on Pig, 1. The test holes (nominal 12
inch dianieter by 12 inch deep) were hand dug at the bottom of shallow backhoe pits
and Nverc soaked with water one day prior to testing, The soils exposed its the
percolation holes are similar to those exposed in the Profile Pits 1 and 2. shown on Pig.
2 and consist of about 1 foot of topsoil overlying basalt fragments up to boulder size is
k a calcareous sandy clay matrix. The percolation test results are presented in 'fable 11.
Tl>9- percolation test results indicate an infiltration rate between 45 and 90 minutes per
irich -with an average of about 60 rninutes per inch. Based on the subsurface conditions
encoumered and the percolation test results. .:
infiltration septic disposal system.
I.,UR atiunst This study has been conducted in accordance with generally accepted
geatechnical engineering principles and practices in this area at this, time. We make no
warranty either expressed or implied. The coiaclusions and recommendations submitted
in this report are based upon the data obtained from the exploratory pits excavated at the
locations indicated on Pig, 1, the proposed type of construction and our experience in
tho area, Our findings include interpolation and extrapolation of the subsurface
conditions identified at tho 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
not! fled at once so are -evaluation of the recornmendations may be made,
This report has been prepared for the exclusive use by our client for design purposes.
We are not responsible for technical inEerpretations by others of our information, As
the project evolves, we should provide continued consultation and field services durinb
