I have spoken with Kevin of KC Construction by telephone on the morning of 06/04/03. The proposed
construction of the sewer line under the driveway area at the above referenced project will consist of Schd
40 PVC piping insulated with minimum 1" high density "Blue Board" (or comparable) insulation overlain
by a minimum of 24" of soil. The proposed construction is sufficient to assure the structural integrity of the
sewage line under the driveway and backfill across the d=_-_— area may proceed. Ends of the driveway
crossing should be left exposed to facilitate verification of the insulation and depth of cover during the final
inspection of the ISDS. Please call if you have additional questions concerning this issue.
Thank you,
Tom A. Cronk, P.E. (No. 28322)

F1.0 Site History
The site consists of approximately 2.088 acres of cultivated native soils. Natural drainage in the area of
concern is approximately 4.0% to the west. A perc test/soils evaluation was conducted at the site on
10/14/02 by Tom A. Cronk, registered professional engineer (R.P.E.). A soils observation excavation and
C three perc excavations (referred to as excavations A, B, and C) were prepared on the site. The locations of
the soils observation/perc excavations are shown on the attached plot plan.
The 10/14/02 investigation was intended to develop subsurface design parameters for a new individual
sewage disposal system (ISDS) to serve a new residence at the property. As based on results from the site
investigation, an engineered ISDS design has been prepared. Results of the perc test/soils evaluation are
r attached for reference as Appendix A. A discussion of developed subsurface design parameters and the
L engineered ISDS design follows.
r 2.0 Development of Design Parameters
I
A soils observation trench was extended to a depth of 96" below ground surface (BGS). There was no
evidence of ground water or high seasonal water table in the open excavation to a depth of 96" BGS. The
Csoils evaluation indicates four distinct soil horizons underlie the site. A lithological description follows:
depth in. description
0" - 18" silty clay/sandy clay, red; blocky; friable
18" - 36" silty clay, light red; hard and blocky
36" - 72" sandy clay/clayey sand, chalky white; friable; some gravel to cobbles
72" - 96" sandy clay, tan with light gray flecks; friable
As based on the results of the perc test (Appendix A), an average design perc rate of 49 min/in. is chosen
for overall sizing of a trench absorption field. A LTAR of 0.46 is chosen as being representative of the
clayey sandy sandy clay subsoils at the site.
Page 2 of 8
F3.0 System Designn
C A INFILTRATOR trench absorption field is proposed for discharge of septic effluent at the site. Natural
drainage in the area of the proposed absorption trench is approximately 4% to the west. The absorption
trenches will be oriented with their lengths perpendicular to the existing slope as shown on the attached
septic layout plan. Construction of the system will consist of excavating level trenches in the area
comprising the absorption field. The initials excavations shall be continued to the chalky white sandy
clay/clayey sand soil horizon or a depth of 36 BGS, whichever depth is greater.
FFollowing completion of the initial trench excavations, INFILTRATORS will be used to construct a septic
effluent distribution system in the open excavation. The INFILTRATOR effluent distribution system will be
installed in accordance with the "Infiltrator Technical Manual", available from Infiltrator Systems Inc., 123
Elm Street, Suite 12, Old Saybrook, Connecticut 06475. Adjacent INFILTRATORS shall be fastened with
a minimum of four (4) 3/4" x #8 self -tapping sheet metal or bright brass deck screws to prevent movement
and separation during backfilling. As shown in the Construction Detail, the bottom of the INFILTRATOR
Cseepage trench will be located an approximate depth of 36" below ground level.
Because of the sloping site topography, the absorption trenches must be terraced down the hill side as shown
in the attached septic layout plan. Adjacent infiltrator trenches must be separated by a minimum of 6' of
L undisturbed soil. Septic effluent will be transferred from the upper trench to each adjacent trench down the
slope through a serial distribution network as shown in the attached construction details. The serial
distribution connections between adjacent trenches will facilitate the saturation of the up hill trench before
septic effluent is allowed to flow to the adjacent downhill trench.
After installation of the INFILTRATOR trenches has been completed, the absorption field will be covered
with a soil cap. The soil cap will consist of approximately 24" (10" minimum required) of native soil
mounded 5% to promote surface run off away from the absorption field.
The installer should confirm the feasibility of gravity discharge of ground floor sewage effluent from the
residence to the absorption field by field verification of assumed design parameters. Assumed design
parameters with respect to gravity discharge include:
`l • distance from the sewage pipe at exit from the foundation line to the absorption field -100'
or less,
• elevation of the ground surface at entry to the absorption field shall be equal to or below the
invert elevation of the sewage pipe at exit from the foundation line.
A non -clog pump and storage vault with a minimum 2" solids handling capacity will be required to lift
basement plumbing effluent into the septic tank. The basement lift pump and vault must be installed in
accordance with all relevant UPC and Eagle County requirements and regulations.
The installer must also confirm the setbacks from property lines, building envelopes, and existing easements
shown in the attached graphics are maintained. Additionally, any unknown utility lines, easements, or other
adverse conditions disclosed during construction must maintain the required setbacks listed on page 5 of this
document. A minimum of 18" of soil cover is recommended (10" required) for all ISDS elements (excepting
maximum 8" soil cover over septic access ports).
Page 3 of 8
F
l
The ISDS will serve a four bedroom home. A 1,250 gallon septic tank is required for retention of sewage
effluent for the proposed four bedroom home. A non -corrodible filter shall be installed at the final outlet
Tee of the septic tank or in the effluent line between the septic tank and the absorption field to limit the size
L of solids and sludge passing into the absorption field. The filter must be accessible for cleaning and
replacement from the ground surfaced.
CAs discussed above, INFILTRATOR absorption trenches are proposed to discharge septic effluent to the
underlying sub -soils. As shown in the attached graphics, the absorption trenches will consist of four (4)
C trenches Y wide x 3' deep. The four trenches will contain a total of sixty four (64) standard infiltrator units
configured in serial distribution as shown in the attached graphics. The absorption field will encompass a
gross area of 1,200 square feet with an effective area (31 sq. ft. allowed area/INFILTRATOR) of 1,984 sq.
C ft.
Calculations and design parameters used to size the absorption field follow.

F4.0 Site Specific Installation/Operation Requirements
C The owner and system contractor shall be aware and comply with the following installation and system
operation requirements.
C4.1 Installation - Setbacks, Notifications, and Inspections
• All installation activities shall be conducted in accordance with c urrent Eagle County
r Environmental Health Department (ECEHD) ISDS Regulations. If at any time during
construction, subsurface site conditions are encountered which differ from the design
parameters developed in Section 2.0, construction activities will stop and the design
Cengineer will be contacted to address any necessary design modifications.
• Installation procedures including grade, location, setbacks, septic tank size, and absorption
field size shall conform with the attached graphic details. Construction activities and
system components will not encroach upon existing easements or utility corridors. A
minimum of 10' of undisturbed soil shall be maintained between individual absorption
elements and the septic tank. Adjacent absorption elements shall maintain a minimum
separation of 6'. Minimum site specific setbacks for system components are:
Source Septic Tank Absorption Field Building Sewer
water line 10' 25' 10'
dwelling 5' 20'
property lines 10' 10'
- domestic wells 50' 100' 50'
subsurface drain 50' 50' 50'
and dry well 50' 50' 50'
irrigation ditch
open 50' 50'
lined/gated 25 25'
solid pipe 10' 10'
• To avoid surface flow infiltration and saturation of the new absorption system,
abandonment of flood irrigation within 50' of any ISDS element is required.
• A non -corrodible filter shall be installed at the final outlet Tee of the septic tank or in the
effluent line between the septic tank and the absorption field to limit the size of solids and
sludge passing into the absorption field. The filter must be accessible for cleaning and
replacement from the ground surfaced.
• All sewer lines and effluent distribution piping shall be 4 inches in diameter and have glued
joints. INFILTRATORS shall be placed level in the absorption field. All lines discharging
sewage from the residence to the septic tank shall maintain fall of between 1/8 in. and 1/4
in. per foot and shall employ sweep 90's or 2-45's at all turns. Sewer 1 ines f rom the
dwelling to the septic tank and at least 6 ft from the septic tank outlet must meet minimum
- standard ASTM-3034. Sewer lines under driveways shall always meet minimum Schedule
40 PVC standards and shall be encased with corrugated metal pipe when covered with less
than 24" of soil. Additionally, all effluent lines under traffic areas shall be insulated with
Page 5 of 8
min. 1" thick X 18" wide high density foam ("Blue Board" or equivalent) centered over the
effluent line to prevent frost penetration.
C• A minimum of 10" of soil cover (18" recommended) shall be maintained over all ISDS
components (excepting maximum 8" cover over septic access ports).
• The installer shall not backfill the open excavation until inspected and approved by the
design engineer. Additionally, the final cover shall not be placed on sewer lines, septic
tank, or the absorption area until the system has been inspected and approved by the design
Lengineer and as required by the Eagle County Environmental Health Department.
• The installer shall provide 48 hour notice to the engineer and the ECEHD for all required
inspections.
• The effluent distribution system shall be constructed in accordance with the "Infiltrator
Technical Manual" available from Infiltrator Systems Inc., 123 Elm Street, Suite 12, Old
Saybrook, Connecticut 06475.
• Adjacent absorption trenches shall be connected by a serial distribution system to assure the
saturation of up gradient trenches before septic effluent is transferred to down gradient
trenches.
• The surface cap shall be mounded 5% over the absorption field to promote surface runoff.
• The system contractor shall be aware of the potential for construction activities to reduce
soil permeabilities at the site through compaction, smearing, and shearing. The following
precautions and construction procedures should be employed during installation to
minimize disturbance to native soils:
i. Excavation should proceed only when the moisture content of the soil is below the
plastic limit. If a sample of soil forms a rope instead of crumbling when rolled
between the hands it is too wet and should be allowed to dry before excavation
continues.
ii. Excavation and backfill equipment should work from t he su rface w here a t all
practical to avoid compaction of the soils at depth.
iii. The bottom and sidewalls of the excavation should be left with a rough, open
surface. The appearance should be that of broken or ripped soil as opposed to a
sheared, smeared, or troweled surface. Any smoothed or smeared surfaces should
- be removed with a toothed rake or shallow ripper taking care to remove loose
_ residues from the bottom of the excavation by hand if necessary.
iv. Care should be taken in placing fill materials in the excavation to avoid damaging
the exposed soil surfaces.
4.2 Operation - Maintenance and Inspections
• The owner shall install a structural barrier if necessary and take precautions to prevent
vehicular traffic, excessive surface watering, accidental flooding, or other activities in the
Page 6 of 8

•
vicinity of the absorption field which may compact, saturate, or otherwise alter the
subsurface soil parameters used in designing the septic system.
Plumbing fixtures will be inspected and maintained as necessary to prevent leaks (e.g.,
dripping faucets and hissing toilets, etc.) which may result in overloading the ISDS.
The owner will plant and maintain grass or other shallow rooted cover crop to prevent
erosion and promote evapotranspiration over the absorption field.
The owner will inspect and maintain the required mounding and drainage away from the
absorption field to prevent saturation from precipitation and surface flows.
To mitigate the generation of preferential flow channels which may compromise the
operation of the system, the owner will inspect and prevent intrusion of burrowing animals
and deep rooted plants into the absorption field.
The owner will conduct periodic maintenance and cleaning of the septic system in
accordance with the following schedule at a minimum:

1.0 Soils Evaluation
The site consists of approximately 2.088 acres of uncultivated native soil. Drainage is approximately 4%
to the west. A percolation test/soils evaluation was conducted on the property of reference on 10/14/02 by
Tom A. Cronk, registered professional engineer (R.P.E.).
A soils observation trench was extended to a depth of 96" below ground surface (BGS). There was no
evidence of ground water or high seasonal water table in the open excavation to a depth of 96" BGS. The
soils evaluation indicates four distinct soil horizons underlie the site. A lithological description follows:
de th in. description
0" - 18" silty clay/sandy clay, red; blocky; friable
18" - 36" silty clay, light red; hard and blocky
36" - 72" sandy clay/clayey sand, chalky white; friable; some gravel to cobbles
72" - 96" sandy clay, tan with light gray flecks; friable
_ Three perc holes were constructed at depths of approximately 20"-24". The holes appeared to be well
saturated at the time of the test. Results of the percolation test are shown in Table 1.

2.0 Conclusions and Recommendations
Soils at the site appear acceptable for implementation of an individual sewage disposal system (ISDS). The
following site -specific considerations should be observed during implementation of the ISDS:
• The bottom of the ISDS absorption field should be located no deeper than 48" BGS to
maintain 4' of usable infiltration soil above the extent of the soils observation excavation
located at 96" BGS. An average design perc rate of 49 min/in. is recommended for overall
system sizing.
• Care should be taken during construction to avoid compaction and smearing of the exposed
infiltrative surfaces and preserve the natural permeability of the native soils.

3.0 Limitations
This report provides a professional assessment of the feasibility of implementing an individual sewage
disposal system on the property of reference. The design parameters developed in this document are
representative of the site conditions disclosed at the specific time of the site investigation. Site conditions
are subject to change from external events both manmade (irrigation or pond construction) and naturally
occurring (flooding or excessive precipitation). Cronk Construction Incorporated is not responsible and
accepts no liability for any variation in assumed design parameters caused by external events.
Cronk Construction Incorporated represents this report has been prepared within the limits prescribed by the
owner and in accordance with the current accepted practice of the civil engineering profession in the area.
No warranty or representation either expressed or implied is included or intended in this report or in any of
our contracts. %f
