Re: Chapman Fishing Lodge
Dear Mr. Byrnes:
ENVIRONMENTAL HEALTH DEPARTMENT
On November 1, 1996, ,1 inspected the installation of the
subsurface drain which was constructed to divert the
groundwater and irrigation water from reaching the leach
field on the referenced property.
The subsurface drain was installed to the engineer's
specifications (letter and design dated July 29, 1996) to at
least a depth of 12 inches of gravel around the northern and
eastern portion of the leach field and also around.the
southeastern portion of the tanks. The integrity of the
tanks was also inspected by this Department and the
contractor. All inlets, outlets and their seals were
examined, and the risers were sealed:
Please contact this Department,if there are any further
questions or concerns.
Sincerely,
Betse, Kip
Environmental Health Officer

Dear Mr. Byrnes,
We and our representative Bob Nelson observed the installation of the
subsurface drain at the septic tank and above the field at the subject
site. The installation was required because of seasonal ground water
and described in our letter of July 29, 1996.
The risers at the septic tank and 'lift station were i0water-proofed' to
minimize infiltration to the tanks. A subsurface drain was then
installed from the tanks, along the east side of the field and then
westward to a positive gravity outlet.
The drain was installed in general conformance with recommendations of
our July 29, 1996 'letter.

Subject: Ground Water and Proposed Subsurface Drain
Chapman Fishing Lodge
Tract 10, Lot b, Aspen River Valley Ranch Subdivision
Pitkin County, Colorado
Job No. 6726
Dear Mr. Byrnes,
We met with you and Bob Nelson on July 18, 1996 at the site to observe
the onsite wastewater system (OWS). The system was designed in our
letter of November 10, 1995. This spring there has been ground water
above the 2.5 feet identified by Hepworth Pawlak in their subsurface
investigation 195 401.
We understand ground water was observed at a depth of 1 foot during
the spring and there was surface irrigation being done at the same
time. The surface irrigation has been stopped, although we believe
some irrigating can be done this fall to establish vegetation above
the mound.
To lower the seasonal water level, we recommend installation of a
subsurface drain. The drain should consist of an excavated trench to
a minimum depth 1 foot below the top of the second septic tank which
gravity outlets to the northwest. The alignment of the drain and a
cross section are presented on Figs. 1 and 2. With excavation of the
trench, a minimum of 4 inches of 1.5 inch gravel should be placed,
then installation of a 4 inch perforated pipe, then placement to
establish a total of at 12 incites of gravel. The pipe should a mini-
mum slope of 1% downward from the second septic tank. When the drain
is installed, the connection between the "risers" and tanks and risers
themselves should be waterproofed.

I represent the Dart Family, which owns the ranch downstream from you. As
you know from the ranch foreman, Don Cramer, the septic system on the house you
are building for Chapman is malfunctioning. Mr. Cramer indicates that raw (but
diluted) sewage is entering the Wheatley Ditch, which provides irrigation to the
Dart property. That sewage is polluting the several lakes on the Dart property, and
potentially the Roaring Fork River beyond the lakes. In addition, it could pollute
the two wells servicing the houses on the Dart property.
This is to demand that you immediately cease using any facilities in the
Chapman house that utilitze the septic system; that you pump the system, and that
a plan be devised to prevent reoccurance in times of high ground water (i.e., every
year at this time). Otherwise, we are authorized to take all steps necessary to
protect our clients' rights.

We observed the installation of the OSDS at the subject site. We
observed installation of the field and all components on May 8, 1996.
The electrical components were not complete at that time, but have
subsequently been installed and observed.
Suitable filter material was provided and the cover material was prop-
erly placed. The system was installed in general conformance with the
design plans and specifications of our letters of November 10, 1995
and the revision of December 10, 1995.

Job No. 6726
Dear Mr. Byrnes,
The purpose of this letter is to provide revisions of the Onsite
Sewage Disposal System (OSDS) for the subject site. The revision is
related to distribution of effluent in the mound field.
The revision is to provide pressure distribution for the field. Four
laterals of 1.5 inch pipe are proposed with fourteen 0.25 inch holes
per lateral, 7 foot on center. The manifold is proposed as 2 inch
pipe. The pressure distribution system is based on a 20 foot head
which includes: 5 feet of head at the orifices, 5 feet of head from
the pump to the laterals and 12 feet of head loss due to friction
loss. The proposed system is to be pressurized by a 0.5 HP Gould
pump, Model 9885.
We understand the system is installed properly at this time except for
the pump. When the pump is installed a final letter will be submit-
ted.
If there are any questions, or if we can be of service if you find
another site, please call.

Dear Mr. Byrnes,
We understand the 5300 square feet (SF) size of the Lodge we were
informed of is incorrect. The actual size is 7800 SF. This affect
the design of the onsite wastewater treatment system (OWTS). Because
the size is greater than 6000 SF and loading of 130 gallons per day
(GPD) per person is required. Attached are revisions to our design
based on the 130 GPD loading.
The septic tank capacity is 3000 gallons, which we proposed in two
1500 gallon septic tanks. The tanks should be installed as indicated
on Fig. 2. A detail of the lift station is presented on Fig. 4.
The field area requires 2900 SF sand filter infiltration area and 2251
SF of basal area. The controlling area is the sand filter area. We
recommend an infiltration area of 2900 SF and a basal infiltration
area of 3100 SF as indicated on Fig. 3.

Subject: Subsoil Study for Foundation Design, Proposed Residence, Lot B, Parcel
10, Aspen River Valley Ranch, 1900 Lower River Road, Pitkin County,
Colorado.
Dear Jim:
As requested, Hepworth-Pawlak Geotechnical, Inc. performed a subsoil study for
design of foundations at the subject site. The study was conducted in accordance with
our agreement for geotechnical engineering services to you dated August 21, 1995.
The data obtained and our recommendations based on the proposed construction and
subsurface conditions encountered are presented in this report. We previously provided
an Interim Report letter to you dated August 31, 1995.
Proposed Construction: Plans for the proposed residence were conceptual at the time
of this report. We expect the residence will be one to two stories of wood frame
construction with a slab -on -grade main floor located on the site as shown on Fig. 1.
Cut depths are expected to be shallow, about 3 to 4 feet. Foundation loadings for this
type of construction are assumed to be relatively light.
When building plans have been further developed, we should be notified to reevaluate
the recommendations presented in this report.
Site Conditions: The site was a vacant hay field at the time of our site work. A small
shed was located west of Profile Pit 2. The site slopes gently down to the west towards
the Roaring Fork River. An irrigation ditch crosses the site as shown on Fig. 1.
Vegetation at the site consists mainly of grass with cottonwood and willow trees and
brush west of the irrigation ditch A relatively new, 2 story wood frame house is
located to the southeast of the subject site.
Subsurface Conditions: The subsurface conditions at the site were evaluated by
excavating three exploratory pits at the approximate locations shown on Fig. 1. The
logs of the pits are presented on Fig. 2. The subsoils encountered, below about '/2 foot
Byrnes and Associates
October 6, 1995
Page 2
of topsoil, consist of medium dense cobbles and boulders in a sandy gravel matrix.
Loose clay and sand was encountered overlying the cobbles and boulders in the leach
field areas to depths of 2 to 3 feet. Free water was observed in the nits at the time of
excavation between 2 '/a and 5 feet. The upper soils were very 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 cobble and boulder soil designed for an allowable
soil bearing pressure of 3,000 psf for support of the proposed residence. Footings
should be a minimum width of 16 inches for continuous walls and 2 feet for columns.
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. Dewatering of footing excavations will probably be needed.
Exterior footings should be provided with adequate cover above their bearing elevations
for frost protection. Placement of footings at least 42 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 10
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 45 pcf for the
on-site soil as backfill. We recommend that excavations be kept as shallow as possible
and the main level floor be slab -on -grade due to the high groundwater observed at the
site.
Floor Slabs: The natural on-site soils, exclusive of topsoil, are suitable to support
lightly to moderately 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 less than 50% passing 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 soils devoid of vegetation, topsoil and oversized rock.
However, due to the high moisture and boulder content of the on-site soils it may be
more practical to use imported sand and gravel as structural fill.
Surface Drainage: The following drainage precautions should be observed during
construction and maintained at all times after the residence has been completed:
1) 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.
2) 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 6 inches in the first 10 feet in unpaved areas and a minimum slope of
3 inches in the first 10 feet in pavement and walkway areas.
Percolation Tests: The percolation tests were performed in two areas; northwest of the
house and southeast of the house. The test results are shown on Table I and II. The
percolation rates northwest of the house averaged about 13 minutes ner-nch. The
percolation rates southeast of the house averaged about 40 minutes per inch. We
understand an engineering "mounded" system is proposed due to the high groundwater
level.
Limitations: This report has been prepared in accordance with generally accepted
geotechnical engineering principles and practices in this area at this time. We make no

other 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 Fig. 1, the proposed type of construction and our
experience in the area. 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 soil engineer.
If you have any questions or if we may be of further assistance, please call our office.

Subject: Onsite Sewage Disposal System Design, Proposed Residence
Chapman Fishing Lodge
Tract 10, Lot B Aspen River Valley Ranch Subdivision
Pitkin County, Colorado
Job No. 6726
Dear Mr. Byrnes,
As requested, we have prepared an onsite sewage wastewater system
(OSTS) design for the subject site. The design is based on a review of
plans, and subsurface data by Hepworth Pawlak Geotechnical Inc (HP).
The soils data from HP should be included as a part of the Individual
Sewage Disposal System Permit. The basis for the requirement for a en-
gineer designed system is the lack of 4 feet of suitable soil beneath
the field before encountering water.
SITE CONDITIONS - The investigated site is a 13.5 acre lot located in
a rural Pitkin County, Colorado as indicated on Fig. 1. Most of the
property is southwest of the Roaring Fork River. The smaller portion
of the site is northeast of the river, although this is where the
lodge is proposed. To the northeast of the Roaring Fork River, the
ground surface slopes gently to the southwest at the proposed absorp-
tion field site, as indicated on Fig. 1. There is an irrigation ditch
to the northeast of the proposed field. The proposed field must be
maintained 50 feet from the ditch' the ditch must be lined and main-
tained a minimum of 10 feet from the field. The ground surface slopes
at 3% at the proposed field area.
PROPOSED CONSTRUCTION - At the time of our investigation a 4 bedroom
„residence was proposed as indicated on Fig. 1. Two additional bedrooms
-V are planned for a detached caretaker unit. The total area of the
structures is 5300 square feet (SF), 4300 SF in the main building and
oo 1000 SF in the caretaker's unit. The average sewage load for a 6 bed-
room dwelling is 1200 gallons per day (GPD), 2100 GPD with a 1.75
Pitkin County facto r' esign flow. The residence will be provided
{� water by an onsite well.
SUBSURFACE CONDITIO - Subsurface conditions were investigated by HP
Geotechnical. Subsoils consisted of 1.5 to 2.5 feet of clay and sand
underlain cobbles and gravel in the leach field areas. Ground water
was encountered in the test pits at 4 to 5 feet in the leach field
areas. The results of the percolation tests indicate rates ranging
from 11 to 17 minutes per inch (MPI) to the northwest of the house and
20 to 60 MPI to the southeast of the house.

(303) 832-9692 FAX (303) 832-3517 (303) 674-0660 FAX (303) 674-0813
RECOMMENDATIONS - We recommend a OSDS with a lift st �ionand mounded
sand filter field be installed at the location i ed on Fig. 2.
The OSDS should be designed for a sewage load o 2100 G and a perco-
lation rate of 17 MPI. An OSDS design based on age load of 2100
GPD and a percolation rate of 17 MPI is presented on Figs. 2 through
4. The minimum septic tank capacity is 2500 gallons, which we recom-
mend in one 1500 gallon single compartment septic tank followed by a
1000 gallon single compartment septic tank. After the septic tanks,
a lift station consisting of a 1000 gallon single compartment septic
tank with a minimum 1/3 H.P. pump should be installed as indicated on
Fig. 4. The pump will distribute effluent throughout the field rather
than using only portions of the field. The minimum area requirement
for sand filter infiltration is 2200 SF using an application rate of
0.95 gallons per square foot per day. As indicated on Fig. 2, the
field has a basal infiltration area of 2400 SF in the natural soil.
Surface vegetation should be removed and the surface soils scarified
to a depth of 6 inches on the low side of the field. The bottom of the
field should be excavated level which will result in an excavation of
approximately 2 feet on the uphill side of the field. We recommend
excavating the field with a backhoe from above the field or track
mounted equipment to minimize compaction of the infiltration area. If
excavated with rubber tired equipment, the infiltration surface must
be scarified before placing filter sand. Filter sand should then be
mounded to a minimum depth of 2 feet. The filter sand must be approved
by this office and should consisted of unwashed fine sand meeting the
following specifications: 1. maximum of loo passing ##200 sieve, 2.
maximum size 1/2 inch, 3. 50o retained between #16 and #100 sieves.
The 1 1/2 inch gravel the 4 inch sewer pipe should then be placed.
Straw, untreated roofing paper or landscaping filter fabric should be
placed on the gravel. The entire field must then be covered with a
minimum of 1.5 feet of soil. The fill over the field should extend a
minimum of 3 feet laterally from the edge of the gravel before begin-
ning the slope to the natural ground surface. Side slopes must be
graded to 3:1 (horizontal to vertical) until the natural slope is met.
The disturbed surface and top of the mound should be seeded after com-
pletion of the installation. We recommend a "dryland, pasture, or
foothills" seed mix, which will grow with natural precipitation, and
requires no irrigation. No irrigation should be done over the field.
The owner must realize an OSTS is different from public sewer service.
The owner must be aware of and assume the responsibility for mainte-
nance. We recommend the pumping of the first septic tank at the end
of the first year of use to monitor sludge accumulation. The tank
should be pumped at least every two years. There are daily considera-
tions, such as not putting plastic or other nonbiodegradable material
into the OSTS. Water use must be carefully monitored, so toilets are
not allowed to run when seals malfunction. To illustrate the point, it
should be noted a running toilet will consume in excess of 1000 GPD if
allowed to run. As the system is designed for 2100 GPD, an excess 1000
GPD will flood and harm the system.
We caution you against installation of a water softener. The hydrau-
lic loading from the backwash of a water softener can detrimental to
OSTS and a separate drywell should be constructed for the backwash, if
a water softener is installed. Also no harsh chemicals such as for
cleaning or photographic processing should be introduced into the

Is
OSTS. No landscaping or plastic.should be used over the field. No
surface irrigation is allowable above the field.
LIMITATIONS - Our investigation, layout, design and recommendations
are based on data submitted. If subsurface conditions different from
those described in this report are encountered, we should be notified
to evaluate the affect of the changes on the proposed OSTS. If chang-
es are dictated by gov_ health departments, we should be contact-
ed to evaluate the
