JUNE 1971
INTRODUCTION
This report is the result of our field geologic and soil investigation
conducted June 15, and July 3, 1971, on the McKinley Heights Subdivision
Addition No. 2; legal description: N.E. 1/4, Sec. 20, T15N, R1W, S.M.
The McKinley Heights Subdivision is a newly proposed residential
area being planned without the benefits of public water and sewer utilities.
It will therefore be the responsibility of each lot owner to provide for on-
site sewage disposal facilities and a potable water supply.
The sewage disposal units will consist of conventional septic tanks
draining into a seepage pit and/or drain fields. The water source will be
from individually drilled and cased wells.
The purpose of this investigation was to define in detail the soils con-
ditions existing at the above mentioned subdivision in order to help us in
determining the area requirements for proper sewer seepage in the particular
soil found.
INVESTIGATION
Our investigation consisted of a review of all available geologic data
pertaining to this area, followed by a thorough field reconnaissance of
the road cuts (indicated by the shaded portion of the enclosed plat).
A drilling program was not initiated on this property because of the
depth and location of the road cuts on the property and in the near vicinity.
SUBSURFACE SOILS AND CONDITIONS
Specific types and depths of soils and conditions are shown on the
enclosed typical cross-section. The soils were found to consist of glacial
"till"
Under the 8 to 12 inch layer of organic matter there is an 18 inch to
to a 3 foot wet, dark brown layer of sandy organic silt. This is thickest on the
western half of the property. Under this is a wet, light brown to gray
unsorted mixture of sand, gravel, and cobbles with many boulders and a trace
of silt. This material is interrupted randomly throughout with layers and
lens of coarse sand.
The soils were found to be frozen to a depth of at least 1~.5 feet (the
deepest of the road cuts).
CONCLUSION
From the information gathered during our investigation we conclude that
the soil conditions are well suited for the proposed residential development.
The percolation qualities of the soils make this an ideal location for on-
site sewage disposal, using septic tanks with seepage pits or drain fields.
The seepage area requirements for individual systems based upon a
12 foot deep pit with 2 feet cover will range from 150 square feet per
bedroom in the easterly portion to 190 square feet~per bedro6m ih,the westerly
part of the development.
If the normal precautions are taken while installing both the water well
and the sewage disposal system and the proper spacing is utilized, there
should be no contamination of the water wells on the property or adjacent
properties. The lot sizes proposed in the McKinley Heights Subdivision are
more than ample for the type of development nroposed.
