INTRODUCTION
I was contacted in April of 2013 by Mr. Mark Fenton who requ c sted my investigation a id
documentation of slope stability and landslide hazard issues rel ting to improvements p anned on his
residential properties identified above. The Fenton properties located in an area appi oximately
six miles west and north of Shelton, Mason County Washington.
I've visited the property in April and May of this year to collec 'topographic informatio and verify
measurements and feature locations. Measurements were made using a Sokkia model No. 8047-55
inclinometer, 100 foot and 300 foot long fiberglass surveyor's I apes and other field equipment
common to surveying. Software employed in creating a site plan and writing this report included
AutoCAD 2006, a Terrain 3-d contour modeling program, GA �NA Slope Stability alysis
software, and Microsoft Office Word 2003.
The slopes located on the Fenton properties range from level o the north end of the two parcels to
p p p
slopes ranging between 35 and 38% on the southerly portion ofthe easterly parcel (Tra t 42).
Neither of the two Fenton properties contains slopes greater than 40%,but both parcels are within
300 feet of slopes on an adjacent property that were measuredw.60% over an elevation difference of
approximately 40 feet. A gravel borrow pit has been develope on the property immediately west of
the southerly half of parcel 42008-14-90042 and immediately outh of parcel 42008-14 90043. The
pit slopes were measured at 60%towards the north and east. The gravel pit and slopes e identified
on the attached site plans as a HAZARD AREA because the pit slopes are greater than 0%with
more than 10-feet of vertical relief. The upslope geomorpholog of the Fenton property may be
described as flat.
Because of the steep slopes (>40%under Mason County termij iology) on or within 300 feet of the
owner's properties, Mason County requires a geotechnical repo be prepared to addres potential
stability issues relating to the properties' development.

The following thirteen elements are required by Mason County I o be addressed in geote hnical
reports prepared to comply with Mason County's Critical Reso ce Ordinance Sections 17.01.100
through 17.01.104.
1. SURFACE AND GEOLOGIC CONDITIONS:
The property is located in the rolling foothills south of the Olympic Mountain range. Nearly all of
the Fenton site has been logged at some distant past time and now is typically covered vith a fairly
even age stand of second growth timber, comprised mainly of Douglas fir, hemlock, cedar, and Jack
Pine trees.
An Onsite Septic System(OSS) is planned for each of the two cels under Mason Co ty Onsite
Septic System Permits SWG2013-00071 & 00072. Greg Wald 'jck designed the septic s stems.
Discussing soil conditions and depths with Greg, Greg report& that he had designed several septic
systems in the W Dayton Trails community, and that the gravel apparent at the ground ace
extended to a great depth throughout the area. The properties p e no problems for sittit g septic
system components. A water well has been drilled on tract 3 in the location indicated o the attached
site plans.
Inspection of the portion of Department of Natural Resources) eologic map of the Shelton area on
the following page finds the Fenton property located in an area roughly 2 miles east and north of
Dayton and roughly 6 miles west and north of Shelton. The m and onsite investigatio# of the site's
soils reveals the areas surrounding the Fenton property are mai ly Continental Glacial Deposits
(Qgo) described as follows;
Continental Glacial Deposit :
Fraser Glaciation,Vashon Stade
Proglaeial and recessional outwash,late NVisco dnan(Pleisto-
��° cene}--Typically poorly to moderately sorted,rou ded gravel and
sand with localized coarser-and finer-grained co tituents;lithologi-
cally varied mixture of mostly northern-provenanx clasts,especially
containing granitic and metamorphic rocks that ic t ntify the unit as
being deposited by the Puget lobe of the Cordillej an glacier;also con-
tains varying amounts of locally derived Crescen ommation basalt,
and in the Mox Chehalis Creek valley,central C ade Range—
derived andesitic clasts;typically shades of gray ere fresh or
brown where stained especially in proglacial and morainal areas; buff
staining near the ground surface;fume sand,silt,and clay constitute
local overbank sediments having relatively poor er meability or del-
taic foreset bedding along north sides of valleys x.,ith higher permea-
bility;porous and permeable enough to yield small to moderate quan-
tities of groundwater;very poorly consolidated tc oose;moderately
to well-rounded clasts;mostly unweathered with re weathered
reworked clasts;thickness varies and is not well I i town;most com-
monly occupies outwash channels scoured into oi hrough till.

Inspection of Washington State Ecology's Landslide Hazard Maps reveals that the Fenton properties
and surrounding area are classified as STABLE. Further inspection and soil analysis finds the soil to
be classified under the Unified Soil Classification System (US CS) as a GW (well graded gravel &
sandy gravels) soil division. Probing various areas of the Fenton property found fairly c nsistent soil
characteristics over both parcels with roughly 3 feet of moderately compacted gravel over more
consolidated gravel below a depth of roughly 3 feet. No upland water bodies or wetlands were found
anywhere near or on the Fenton properties.
2. SITE PLAN WITH IMPORTANT DEVELOPMENT AND GEOLOGIC F ATURES:
A site plan showing the general topography of the area surrounding the Fenton properti s is attached
in this report's appendix. Plan sheet two of the plan set shows the locations of existing I eologic
features.
3. LOCATIONS OF LOGS OF EXPLORATORY OLES OR PROBES:
The attached site plan shows the locations of soil probing on the Fenton property along ith
measured depths to the underlying more compact gravel layer. The undisturbed areas o the Fenton
property revealed a fairly typical weathered gravel layer 3-feet thick resting on top of a more densely
compacted gravel soil.
4. AREA OF PROPOSED DEVELOPMENT & BO JNDARIES OF HAZARDS,
BUFFERS AND SETBA KS:
The attached site plan shows the locations of the existing and r roposed Fenton property
improvements, the locations of the hazard areas (slopes> 40%1, and the boundary of a 0' buffer
line out from the crest and toe of the steep slopes located near he Fenton property.

The Fenton properties themselves contain no slopes steep enou h to trigger the requirenients for a
geotechnical report level report. The gravel pit excavation on the adjacent property triggered a
geotechnical report level investigation and report, but any deve opment planned for the Fenton
properties will be more than 50-feet away from any hazard area.itself, and no greater separation is
needed to protect Fenton property improvements.
5. CROSS SECTION WITH PROPOSED GRADE CHANGES:
A cross section view of each of the Fenton property parcels is r rovided in the attached I Ian sheets as
well as part of the GALENA Stability Analysis Print-Out. The lurrently anticipated pro erty
improvements will not require the construction of any structur 1 fill sections or changes to the
existing slopes or grades.
6. SLOPE STABILITY ANALYSIS:
The property itself does not display any instability indicators. For stability analysis, the hillside soils
were investigated and have been characterized as moderately compacted gravelly sand to a depth of
roughly 3-feet where the gravel becomes more compact to an i finite depth. Unified So 11
Classification System (USCS)typing places the soils in a GW ymbol category (sandy ravel).
The soils are modeled as a homogenous GW soil characterized with a soil unit weight of 125 lbs/ft3,
a phi angle of 38°, and a cohesion character of 50 lbs/ft2. The f oor of the gravel pit was found to
have standing water, so the gravel pit floor (el. 300) is assumec to represent the phreati water
elevation in the project area.
The slope geometry and soil characteristics provide factors of safety for both Fenton parcels in a
static and a dynamic analysis that exceeds the County's minimum safety requirements. The gravel
pit slopes were measured at 60% or less. Two slopes which could potentially impact one or both of
the Fenton parcels were analyzed with the following Factors o Safety (FoS);
Parcel 42008-14-90042 Tract"2" Cross Section"B"
Static FoS: 1.91 Dynamic FoS: 1.44
Parcel 42008-14-90043 Tract"3" Cross Section"A"
Static FoS: 2.37 Dynamic FoS: 1.72
7. RECOMMENDED SETBACKS & DRAINAGE:
Slope stability analysis indicates that the southerly & westerly descending slopes located west and
south of the Fenton properties are stable in their present geometry and condition and do not represent
a landslide or geological hazard to the anticipated developmen of the properties. Conformance to
building department building setbacks (20' sideyard) will provide adequate separation between the
hazard slopes, hazard area buffers and any property improvements.
File: C:TrojectsTentonlGeo-Rpt 4 of 6 5110/ 013
TAHJA ENGINEERING, Inc.
PO Box 235, Hoodsport, WA Q8548
(360) 877-9512
The gravelly soils on the Fenton properties infiltrate all precipi tion delivered to the gr und's
surface. Drainage from the developed areas of the Fenton prop ies should be disperse into
vegetated areas of the property and allowed to disperse. The se )aration between the anticipated
Fenton property improvements and the hazard area slopes is great enough that storniwaler from the
Fenton properties will have no impact on the neighboring prop rties slopes or the mode ate slopes
(<40%) on the Fenton parcels.
8. CLEARING GRADING AND VEGETATI N MANAGEMENT:
The proposed Fenton property improvements will generally occur in the already cleared and leveled
areas of the property in the northerly half of each tract. No grading or disturbance of the steep
sloping areas on the property are being proposed, so no mitigat n or changes to the moderately
sloping areas of the property appears needed other than the dra age recommendations already made
in this report. Natural vegetation should be promoted on the slc ping areas south of the operties. A
formal clearing, grading &vegetation plan does not appear w anted for the Fenton properties.
9. EROSION AND SEDIMENT NTROL:
Inspection of the Soil Survey of Mason County found Shelton avelly sandy loam and ove
m gravelly sandy loas neither of which are identified in the Co ty's Critical Resource Ordinance as
susceptible to severe erosion when disturbed, and do not requir the development of a site specific
erosion and sediment control plan.
Each of the two Fenton sites has already had an access develop d from W Dayton Trails Drive
which are stable in their present conditions. The planned prope y improvements are generally
located well inside the Fenton property boundaries. The Fentor properties themselves provide
adequate filtration length through natural vegetation to provide for water quality treatm nt before
any stormwater runoff is able to escape the property.
10. ON-SITE AND OFF-SITE IM ACTS:
Construction and completion of the conjectural property impro ements on the Fenton pi operties are
not expected to result in any adverse on-site or off-site impacts
11. SPECIFICATIONS OF FINAL DEV LOPMENT:
Completion of the Fenton property improvements does not require any special specific ions for
project completion other than already made earlier in this repoit and as identified on tht attached site
plans. Building elements are expected to comply with Mason unty's current Internati onal
Building Code or International Residential Code requirements.
12. RECOMMENDATIONS FOR THE PREPARATION F STRUCTURAL
MITIGATION OR DETAILS OF OTHER PROPOSED MITIGATION:
Modeling of the slopes in the proximities of the conjectural property development(s) indicates that
the proposed Fenton property development will be safe. No strictural measures appear necessary
other than ensuring that foundation footings bear on the moder itely compact native soil underlying
the Fenton property, and that stormwater runoff is properly in aged/dispersed to minir iize
concentrated flows of stormwater runoff off the Fenton properly.
