Stevenson residence.
Enclosed is your ISDS Permit No. 1850-99. It is valid for 120 days. The enclosed copy of the
permit must be posted at the installation site. Any changes in plans or specifications
invalidates the permit unless otherwise approved.
Systems designed by a Registered Professional Engineer must be certified by the Engineer
indicating that the system was installed as specified. Eagle County does not perform final
inspections on engineer designed systems. Your TCO will not be issued until our office
receives this certification.
Permit specifications are minimum requirements only, and should be brought to the property
owner's attention.
This permit does not indicate conformance with other Eagle County requirements.
If you have any questions, please feel free to contact the Environmental Health Division at 328-

Dear Mr. Stevenson:
This letter is to inform you that the above referenced ISDS Permit has been inspected and
finalized. Enclosed is a copy to retain for your records. This permit does not indicate
compliance with any other Eagle County requirements. Also enclosed is a brochure regarding
the care of your septic system.
Be aware that later changes to your building may require appropriate alterations of your septic
system.

Re: Stevenson Residence, Aspen Mtn. View Subdivision, Lot 15, Eagle County, CO
HCE File Number 99004.03
Dear Ray:
On May 5, 1999 HCE personnel observed the construction of the ISDS located at 345 Milburn
Court, a.k.a. Aspen Mtn. View Subdivision, Lot 15 in Eagle County. All of the components of
the system had been installed, but no backfilling had taken place. Due to a mis-communication
regarding the type of Infiltrator units to be used, the Contractor was directed to add two more
units. The Contractor subsequently furnished proof that two additional units were installed.
Thus, the installation of the system was in conformance with the intent of the design.
If you have any questions, or need additional information, please contact us.

Subject: Percolation Testing for Proposed Residence, Lot 15, Filing 3, Aspen
Mountain View, Eagle County, Colorado.
Dear Ms. Stevenson:
As requested, Hepworth-Pawlak Geotechnical, Inc. performed percolation testing for
septic disposal design at the subject site. The testing was conducted in accordance with
our agreement for geotechnical services to you dated February 1, 1999. The tests were
conducted to determine the feasibility of an infiltration septic disposal system at the site.
The data obtained and our recommendations based on the subsurface conditions
encountered are presented in this report.
Proposed Construction: At the time of our study, design plans for the residence had
not been developed, but it is assumed that the septic disposal system will be located near
the southeast portion of the lot as shown on Fig. 1.
Subsurface Conditions: The subsurface conditions at the site were observed on
February 3, 1999. One eight foot deep profile pit was dug by the client on February 2,
1999 at the location shown on Fig. 1. The subsoils encountered, below about one foot
of topsoil, consist of low plasticity silty sand clay with basalt gavel to a depth of 21/2
r feet, overlying dense basalt cobbles and baujders in a silty sand clay matrix to the
maximum depth explored, about 8 feet. No free water was encountered in the profile
pit at the time of excavation and the subsoils were slightly moist to moist.
Three percolation test holes (nominal 12 inch diameter by 12 inches deep) were hand -
dug by the client in the bottom of shallow backhoe pits on February 10, 1999. The test
holes were soaked overnight with water and protected from freezing by covering with
straw bales. The locations of the percolation test pits are shown on Fig. 1. The soils
exposed in the percolation test pits are similar to those in the profile pit.
Percolation Testing: Percolation tests were conducted in holes P-1 and P-3 by a
representative of Hepworth-Pawlak Geotechnical, Inc. on February 11, 1999. Test hole
P-2 was disturbed (pit caved in) prior to testing, and was not cleaned out and resoaked
until February 22, 1999. We conducted percolation testing on Test hole #2 on February
23, 1999. The percolation test results, presented in Table I, range from 26 to 90
minutes per inch, with an average percolation rate of 48 minutes per inch. The variable
percolation rates were likely caused by the high rock^ content of the soil. Based on the
subsurface conditions encountered and the percolation test results, the tested area
appears suitable for a conventional infiltration septic disposal system. We recommend
that the system be oversized due to the variable percolation rates. Eagle County may
require that a civil engineer be consulted to design the septic 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 profile pit excavated at the
location indicated on Fig. 1 and our experience in the area. Our findings include
extrapolation of the subsurface conditions identified at the exploratory pit 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.
If you have any questions or require further assistance, please call our office.
