Re: Slope stability review
Lots 160 and 164, Division 4,
Plat of Lake Limerick, Mason County WA.
Vol 6, Page 192
Dear Mr Simmons:
On March 21, 1994 I inspected Lots 160 & 164 referred to abov .
You asked that I inspecte the cut slope and give a determinatioi as
to its stability. I assume that the up-grade area (in Lot 160) will
not be developed into a second single family resident.
OBSERVATION:
The materials exposed by the excavation are layers of glacial till,
gravels, and overburden (duff).
It is my opinion that the existing excavation has not jeopardized the
integrity of the up-grade property. The angle and height of the
slope exposed. by the excavation does not increase the up-gr de
property's sensitivity to internal failure by overturning or slump ng.
However, the angle of repose of the cut slope will be subject to
minor raveling or erosion. You may wish to consider stabilizing the
slope to eliminate the nuisance of raveling.
