Subject: Soils Evaluation and Percolation Tests for Individual Sewage System Design
for Lot 9, Aspen Mountain View Subdivision, Eagle County, CO at 0544 Mountain View
Drive
Dear Rich,
As requested, Nelson Environmental and Wastewater Solutions, Ltd,, performed a $ofas
study and percolation tests to recommend a design for a septic system for the proposed
residence being moved from another part of the property. We conducted this study
according to Sections 4.04 and 4.05 h er IV �l do ividgal Sewage Di gal
Systo of the Eagle County Code on October 4, 1994. We have based our
recommendations on the subsurface conditions encountered.
This planned residence is a two bedroom, two bathroom, two-story house. There is a
potential that the system will be expanded to three bedrooms in the future.
The location of the proposed residence and sewage disposal field are shown on Figure
1. With water conserving toilets, the ultimate wastewater flow from this residence is
estimated to be 450 gallons per day (GPD).
The investigated site is a 3-acre lot on Missouri Heights. The property is served by
subdivision wells. The ground surface, which appears natural in the proposed area of
the absorption field, slopes to the South and Southeast at a 20% grade. The
foundation of the house was staked at the time of our investigation, but otherwise, the
site was vacant. There was a typical vegetation pattern of oak brush, sagebrush,
grasses and cactus over the property.
�[_� .�.i.�li�,• is
A soil profile pit, within 25 feet of the proposed absorption area, was excavated to a
depth of five feet where digging became difficult. No ground water was encountered in
the profile excavation. Bedrock was not present within profile pit. However, there was
an abundance of loose cobble and basalt on the surface and within the subsoil matrix.
The basalt exceeded 40% of the volume below three feet. These rocks were from

three inches to forty -inches in diameter and intermixed with the subsoil from
approximately two feet and down. The soil textures encountered were a clay loam
topsoil about six inches deep, and a calcareous sandy silt about sixteen inches deep
that grades into a matrix of calcareous, very cobbly, sandy clay loam and basalt to the
bottom of the profile hole
Percolation Testiu
The subsurface soil conditions were evaluated with the standard percolation test
procedures at the approximate location shown on Figure I. In two instances the test
Wes were hand dug in the bottom of shallow backhoe excavations. One test hole was
excavated to a depth of thirty-five inches by hand from the ground surface. The subsoil
in which the percolation testing was run, consisted of sandy loam or clay loam. This
soil was well consolidated, and showed little tendency to swell. No smearing or
compaction was observed in the backhoe excavations.
Percolation testing was performed in the proposed absorption area South of the
building footprint. The percolation holes were hand dug in the location of the proposed
absorption field at the bottom of backhoe excavations prepared earlier. Three inches
of gravel were placed in the bottom of each hole. The holes were dug to a total depth
of from thirty-five to sixty inches. The percolation holes were pre-soaked the evening
before the percolation testing by adding ten gallons of water to each hole. Water was
then added approximately every three hours for a period of eight hours before
beginning the percolation test.
The results of the percolation testing are presented in Table 1. These results indicate
the clay loam soils have an average percolation rate of 21 minutes per inch and are
acceptable for an infiltration design for the on -site sewage system. Some variability in
the percolation test measurements can be accounted for because of the varying depth
and because of the presence of the stones in the subsoil.
t tt �t � •.. t � •
The minimum Eagle County requirements for this installation are based on a system
loaded at an average of 460 gallons per day. This flow would require a septic tank of
1000 gallons and a minimum of approximately 700 square feet of standard absorption
trench. However, because of the plat recording, on -site sewage disposal systems
within this subdivision are required to be designed by a registered professional
engineer. We refer you to Dan Cokley of Schmeuser, Gordon and Meyer Engineering

Um�ns; This report has been prepared according to generally accepted practices
in this area for use for sewage disposal design purposes. The conclusions and
recommendations submitted in this report are based upon data obtained from our site
visits at the location indicated. There is some possibility that the nature and extent of
variations in the subsurface soils across the site may not have been evident at the time
of this investigation, and may need additional evaluation if further excavation reveals
conditions different from those described. This office should be advised of any unusual
situations as soon as possible so we may reevaluate our recommendations.
If you have questions or if we may be of further assistance, please call the office.

RE: Backe ISDS, Lot 9, Aspen Mountain View Subdivision
Dear Ms. Blair:
This letter should serve as a final inspection report for the Backe residence Individual Sewage
Disposal System located at Lot 9, Aspen Mountain View Subdivision, Eagle County, Colorado.
The inspection was done Thursday, March 23, 1995.
While on site, it was noted that a new 1000 gallon septic tank, proper piping to and from the
tank, and the specified 24 infiltrator units arranged in three trenches.
This installation was. done according to the revised plans prepared by SGM dated 2/24/95,
and operates properly. Please do not hesitate to call if further information is required.
