RE: Resource and Critical Areas Review for Parcel Number 32232-75-90143; Tract 4 of SP
2058, Union.
Dear Mr. And Ms. Bruce:
Due to the degree of the slope on your property(30%) determined from a site visit in 1994 and
that it is mapped on Mason County's Landslide Hazard Areas, a geo-assessment of your site will
be required prior to permit approval. I have included the main points that should be included
below:
• A discussion of geological conditions in the immediate vicinity of the project, and a
discussion of specific soil types at the project site. Terminology should be consistent with
U.S. Geological maps of Mason County.
• A discussion of ground water conditions at the site, including depth to water and quantity
of surface seepage.
• The approximate depth to hard or dense component soil, e.g. glacial till or outwash sand.
• A discussion of landslide activity in the area(from "Relative Slope Stability of the
Southern Hood Canal Area, Washington"by Smith and Carson, 1977, the Coastal Zone
Atlas, or from records on file with Mason County Community Development).
• An opinion on potential for landslide activity in light of the proposed development.
Enclosed please find the applicable chapter of Mason County's Resource Ordinance that addresses
landslide hazard areas. If you have any questions, please contact me at (360)427-9670, ext. 295.
Sincerely,
Shandra O'Haleck, Senior Planner
Mason County Planning Department
