Subject: T12N R3W SEC 22 L28 M250 - 11020 Totem Rd
Septic System Replacement
Dear On -Site Services Engineer:
The home at 11020 Totem Road is being sold, but it does not have a documented septic system
and cannot be tested for a COSA. We are submitting this permit application for a new system. The
property currently has a home, a cabin with a bathroom, a well, and several septic pipes in the back
yard. We are unable to detennine from these pipes the layout of the existing septic disposal field.
The new system will accommodate the 3 -bedroom home in addition to the cabin.
The ground surface on the lot slopes down toward the northwest corner of the lot between 5-8%
slopes. There are no slopes greater than 25% within 50 feet downslope of the system. Drainage
arrows are shown on the site plan showing the grade and direction of flow. Stormwater drainage
will not impact this septic system. The new trenches will be constructed parallel to the slope as
much as possible.
Due to the time constraints with the home being for sale, we are proposing to use adjacent test hole
information for the design and dig a confirmation test hole before installation. We have collected
test hole information for all of the surrounding lots, compiled into the following table. The
percolation rates varied, but were consistently more than 15 min/in, with the longest rates over 40
and 50 min/in. Our proposed design assumes a percolation rate between 30-60 min/in. Almost
every test hole documented no groundwater with the exception of a test hole on Rons Lot 2, which
indicated groundwater at "10+ feet". This seems to be, not an actual measured level, but instead
documentation that the subsequent trench design had "at least" enough separation to meet code.
We will be digging a confirmation test hole on-site prior to installation. Our trench section assumes
that in this new test hole we will confirm a groundwater reading of at least 12' to the seasonal high,
and 14' to bedrock/impermeable layers.

As the site pian specifies the confirmation test hole prior to installation, we ask that these design
criteria be accepted in lieu of a stamped perk test for design and permitting purposes only.
The new septic system will be a minimum of 100' from all wells and surface water. Please refer
to the attached plan and profile for the septic design. If this design is followed, there will be no
adverse impacts to adjacent properties.
Sincerely,
