FOR WILLOW PROPERTIES
( GARY PETERSON )
OROKC, KINKESCTA
5-30-53 /
On Kay 4~30, 1953 six percolation holes were tested on
each of 10 lots and 3 soil borings taken on each lot as well
in accordance with the provisions of Individual Sewage Sys-
ten Treatment Standards(WPG-UO) adopted in 1976 by the Minn
esota Pollution Control Agency. In addition, other soil bor
ings were taken in lower areas to determine the possibility
of obtaining more than 10 lots but water tables were found
to be very high and the soils were found to be very slowly
permeable.
According to the soils maps and the information we
found in the field, the higher areas had very good soils for
drainfields while the lower areas and swales had extremely
poor soils for drainfields. Thus, we tended to stick to the
higher areas while still leaving room for ample building
sites. Hov;ever, once houses are proposed to be constructed
it .might be desired to shift some of the drainfield areas.
Then r w testing would be reouired and it would be ccvise-
sble to keep as high up o.u the k.ncbr ■.£ was previously tes
ted.

ceptor drains to divert runoff water but this would be men-'
tioned in the system design for the individual houses once
they are ready for construction. If any additional informa
tion is needed, please contact rie.
