RE: Issuance of Individual Sewage Disposal System Permit No.1990-00. Property
Location: 1375 Green Meadows Drive, Carbondale, CO., Kroeger residence.
Enclosed is your ISDS Permit No. 1990-00. 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. Please note any special requirements
that may have been added to the design by this department.
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. Please
notify this office if you have not been contracted to perform this installation.

Dear Mr. & Mrs. Kroeger:
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: ISDS for the Kroeger Residence, Lot 13 Sopris Mesa Subdivision
HCE File Number 2000004.18
Dear Ray:
On December 7, 2000 High Country Engineering personnel observed the construction of
the ISDS located at 1375 Green Meadow Drive, Lot 13 in the Sopris Mesa Subdivision.
All of the components of the system had been installed, and only minor backfilling had
taken place. A 1250 gallon septic tank and 36 Infiltrator Equalizer units with inspection
wells had been installed in 4 trenches. The sewer pipe from the house was installed with
a cleanout outside the foundation, and the installation of the system was in conformance
with the intent of the design. We are providing you with a drawing of the system as
constructed with measurements to the major components of the system shown.
If you have any questions, or need additional information, please contact us.

of locolizecl subsidenct,% Sinkholes were not observed in the inunediato area of the
subject lot. The exploratory pits were, relatively shallow, for foundation design only.
Based on our present knowledge of the site, it cannot be said for certain that sinkholes

owner Should be aware of the potential for sh-&-hole developnifnit.
-Subsurface Coiidifl€►ns: The subsurface conditions all,, the site were evaluated by
cxcavadjig two exploratory bits in the building a:ea and one profile pit in the septic
disposal area at the approximate locations shown. on Fig. 1. The logs of the pits are
prese:rlted on Fig. 2. Tlie sulbsoils encountered, below about 2 to 2r/z feet of topsoil,
