RE: DAVIS RESIDENCE SEPTIC SYSTEM — PARCEL 2467-01-001
ISDS ALTERATION PERMIT NO. 1960-OOA
Mr, Merry,
As requested, I have had the opportunity to make a site visit to the subject residence and have prepared this
letter documenting the current ISDS design in order to satisfy Eagle County requirements, that the system
be designed by a Colorado Registered Professional Engineer.
EXISTING SYSTEM — The existing ISDS utilizes an existing 1,000 gallon septic tank and 400 gallon
dosing chamber. The dosing pump conveys the effluent to a distribution box which in turn splits the flaw
to three existing chambered absorption trenches.
PROPOSED FINAL CONSTRUCTION - As part of this ISDS alteration proposal; the residence was
expanded in size from approximately 1,100 square feet to approximately 3,100 square feet and when
completed will include three (3) bedrooms and three and one half (3-1/2) bathrooms.
SITE CONDITIONS — The lot is located in the Leto Minor Subdivision, in unincorporated Eagle County,
Colorado. The proposed absorption trench extensions will be situated on an approximately 10% to 20%
slope to the northeast of the existing residence, and will extend the existing absorption trenches by
approximately thirty-one (31) feet. Currently there are native grasses covering the proposed leachfield
area.
SUBSURFACE CONDITIONS — The design alteration calculations are based upon percolation tests
preformed in July of 1993, which assume a percolation rate of 20 minutes per inch (MPI). A new soil
profile hole was not prepared in this case. However, based on old photographs of the previous septic tank
excavation, neither bedrock nor high ground water, were encountered in the area. Furthermore, there is no
evidence that the soil strata at the bottom of the new seepage trenches (currently in place) will, in any way,
inhibit percolation or effluent treatment.
MINIMUM DESIGN RECOMENDATIONS — The current 1,000 gallon septic gallon tank, dosing
chamber, and pump will be adequate to handle the increased flow requirements resulting from the increased
house size. Based on the new residence size increase, and a percolation rate of 20 MPI, a minimum of 12
standard infiltrator units are required (see attached design calculations). The infiltrator units should be
connected to the ends of the existing Contactor units. I recommend that a Marifi 140N geotextile fabric or
equivalent be used to cover the seam between the two different types of units. Additionally, I am requiring
three (3) more inspection ports or observations vent pipes with PVC caps, be -installed near the east end of
the absorption trenches.
I also recommend that the east end of the absorption trenches be back -filled such that there is a
minimum of two (2) feet of cover on top of the infiltrator units. Final grading around the trenches should
be provided to channel surface water away from the top of the trench locations.
August 9, 2001
Mr. Ray Merry
Page 2 of 2
MINIMUM SEPARATION REQUIREMENTS — Based on my site visit and a survey of the apparent
physical features in the area, the absorption trench expansion, in this case, will not encroach into any of the
required setbacks listed in the Eagle County ISDS regulations.
OPERATION AND MAINTENANCE — The owner must realize that periodic maintenance of the septic
system is crucial to its long term viability. The septic tank should be pumped once every two (2) years and
the dosing chamber pumped every four (4) years. Pumping equipment and the absorption trenches should
be inspected every six (b) months.
FINAL INSPECTION — Based on my site inspection of the currently constructed system, I am satisfied
that the system, although not backfilled, has been installed thus far, in general accordance with the Eagle
County ISDS Regulations and that the system will adequately handle and treat the additional residential,
sewer flows.
SYSTEM DRAWING OF RECORD — I have attached a drawing of the existing and final systems for
you file.
Please feel free to give me a call if you have any questions, comments, or require any additional
information.

A. ISDS DESIGN CHARACTERISTICS
1.) Total ultimate square footage = 3,100 sq. ft.
2.) Quantity of sewage for type of use:
a.) Single Family dwelling = 75 Gal./person /day
b.) Number of bedrooms = 3
c.) Minimum number of Persons per Bedroom = 2
3. Average Daily Flow Calculation:
Average Daily Flow = (No. of Bedrooms) x (Persons per Bedroom) x (Flow per Person)
= (3 Bedrooms) x (2 Persons/Bedroom) x (75 Gal:/Person/Day)
= 450 Gal./Day
4. Maximum Daily Flow Calculation:
Maximum Daily Flow = 1.5 x (Average Daily Flow)
= 1.5 x 450 Gal./Day
= 675 Gal./Day
1 OF 2

PINNACLE DESIGN CONSULTBVG GROUP, INC.
5. A percolation rat of 20 MPI will be used as the basis of determining the total absorption area size requirements
a.) Minimum Absorption Area Required = (Q / 5) x (T)"(0.5)
A = (675 / 5) x 20A(O.5)
A = 603.74 sq. ft.
b.) Check Minimum Absorption Area Required Based On Long Term Acceptance Rate (LTAR)
Assume that the LTAR = 0.80 for soils having a Percolation Rate of 20 MPI
A = Q /LTAR
A = 675/0.80
A = 843.75 sq. ft.
Use 8" sq. ft. as absorption area required
Existing Absorption Area Approved to be Served By 18 Contactor Units = 403 sq. ft.
Additional Absorption Area required = 844 sq. ft. - 403 sq ft.,= 441 sq. ft.
Number of Std. Infiltrator Units Required to Increase Capacity = (441sq. ft. x 0.5) / (18.75 sq. ftper unr
(assumes a 50% reduction for use of infiltrators)
Quantity = 11.76 Standard Infiltrator U
Use a minimum of 12 infiltrator units
(Note: 15 units were installed)
6. Total Septic Tank Required Volume Requirements.
a.) Design Vol. Required = (675 Gal./day) x (30 hrs)/(24 hrs/day)
Design Vol. Required = (675 Gal./day) x 1.25 = 843.75 Gal.
The existing 1,000 Gal. Septic tank therefore has adequate capacity.

RE: Leto Subdivision Septic Report
Dear Joe:
CONSULTING ENGINEERS i
Per your request in your June 21, 1989, letter to Ken Wilson, you had
requested under item No. 6 a septic report for your submission on the
two lots to Eagle Bounty. ;
Based upon the soils work we performed on site, the following results
were obtained:
1. Hole #1 had an instantaneous perc rate of 14.4 mirVinch
2. Hole #2 had an instantaneous pare rate of 6.9 min/inch
3. Hole #3 had an instantaneous perc rate of 3.7 min/inch
Based upon the information obtained from the perc test results, it
appears feasible that a septic system can be installed on both of these
lots. Percolation rates of faster than 5 min/inch would indicate that
a sand filter -type construction would be necessary. Percolation rates
quicker than 60 min/inch and slower than 5 min/inch would indicate that
a standard system could be installed.
The results obtained in the soils testing performed by our firm indi-
cated that it is a possibility that both systems may be installed on
site. Site specific soils investigations for site specific septic
systems will determine which type of system would be needed. Since the
percolation rates are relatively quick, the field size for a standard
home will be realtively small (on the order of 1000 sq. ft. for a three
bedroan home).
It has been indicated to us that a profile hole was previously done
(approximately one year ago) by Eagle Gbunty. This data will need to
be reviewed to determine depths to bedrock and depths to groundwater.
In any case, with the percolation rates as found, a sand filter or a
standard system could be feasibly installed.
If you have any questions or need further. assistance, please do not
hesitate to call.

RE: Leto Subdivision, Frying Pan River Valle,,,
�
Dear Ken:
I have completed my geologic investigation for purposes of
Senate Bill 35 of the rectangular shaped parcel located north
of the Frying Pan River. Tne property lies in the SW 1/4 of
Section 2, within the Toner Reservoir 7 1/2 minute
guadranple, Eagle County, Colorado. Seven Castles Creei::
"lows through the southeast corner of the lot to be divideo.
The tomography of the parcel consists of rolling to-rafq wizn
dryland vegetation on it but winh some wacland voMeLOU10".
near the stream. There are some gullies t-emming suuio
toward the highway, one o+ which is severe it is M%.,
amdprstanding tnat qn de,aloPmenr will rccu, cm zhe other
side of that gWly ou0 uno sof)s engineur should address a
n,onr/ sethack 4rox' tne yWiy edge if a home is to be located
0ea' il. 5evc-ni abanconed irrigation ditches cross the
'
,i)]g4Wcs v»&uoh ohn parcel. There is an existing home on
the property as shown on the accompanying map, and a bridge
^`oross Seven Castles Creek with a dirt road to the existing
home.
The geology of the site consists of Quaternary age alluvial
deposits laid down by the ancient Frying Pan River; these
deposits are silts, sands, and cobbles laid down in a
stratified manner. These grade uphill to the dominant
surficial deposits of the building sites, colluvium and
alluvial fan daposits of a previously more active gully
system, including Seven Castles Creek. These latter deposits
are now hicher than the present creek can affect, which makes
the proposed building envelopes on this higher ground safer
from debris flow activity. The underlying bedrock is the
Pennsylvanian/Permian age Maroon Formation dipping gently
toward the north. It consists of hematite -cemented
siltstones, sandstones, shales, and some conglomerate beds.
'
A civil engineer should be consulted to locate the one
hundred year floodplain of the creek with respect to this
property. Additionally, gully areas and slopes steeper than
30% should not be chosen for building sites. The old
irrigation ditches should be evaluated after the final sites
have been chosen to see if the ditches should be neutralized.
Undue amounts of water brought to a homesite can de -stabilize
an otherwise stable site.
`
Site specific soils engineering is important on this site to
insure proper foundation design. Waste disposal will
probably need special design because of the steepness of some
of the property, although the soils will percolate well, and
high groundwater or near surface bedrock will not be a
problem. Officer
should be consulted fo, his specific recommendations.
Water for domestic use\���uld be available through the
drilling of a well into the bedrock which is probably twenty
to thirty feet or more below the surface. Water should be
reached within two hundred feet. Access to potential areas
of development will need to be improved but the only
engineering concern is in the crossing of steep slopes.
Radon gas is a potential problem in many parts of the State
but probably not very likely here. It may still be advisable
to design homes with enough ventilation at lower levels to
prevent the accumulation of this gas.
This site is suitable for the development as planned if my
recommendations are followed. Let me re-emphasize that
debris flows from Seven Castles Creek cannot reach the
preferred building sites on the high ground, but judicial
selection of the final site on positive topography and a
landscape design which will direct any flows around the home
is still very advisable. Please contact me if there are
further questions.
