Our geotechnical subsurface exploration report for the referenced project was submitted
to Harmony Ridge Estates on January 12, 2000. Based on the information we developed
as a part of that subsurface exploration, we have been asked to comment on:ubing three
horizontal to one vertical slopes for finished grades on this project. Our evaluation on the
three to one slope for the property is provided with this report.
The materials encountered in the test borings completed on this project site generally
included a thin mantle of sandy lean clay underlain by loose to medium dense clayey
sand. The overburden soils were underlain at varying depths by sandstone or claystone
bedrock. Groundwater was not encountered in the test borings completed as a part of this
project.
We anticipate the three to one slopes fci the project will be developed predominantly in,
natural medium dense to'dense clayey sand. Based on the materials we observed at the
time of our exploration, we behave the three to one slopes could be used in these
materials. Care will be needed to prevent erosion along the faces of the slopes. If slopes
extend to the interface between the bedrock and overburden Soils, those conditions should
be evaluated separately as perched water can reduce the stability of the slopes in these
areas.
