SUBJECT: Leo-Tech Re ort Review___ NAME: Girardin Peter& Christine
Tammi,
The Geotechnical Report prepared for the proposed expansion of the family residence located at
3860 Shelton Valley Rd. has been received and reviewed by Public Works.
The report appears to satisfactorily address County requirements for Geotechnical l Reporting. The
report's author indicates that their analysis of the residential development does not appear to
present any stability problems that cannot be overcome, and will not result in any undesirable
impacts. Slope stability was modeled in both static and etre: e dynamic conditions. The planned
house location provides a 20 foot setback between the house and the crest of the short bank,
which should be sufficient.
Based on the contents of this report, I recommend accepting this report as satisfying the
County's requirements for stability investigation and geotechnicat reporting. Recommendations
and Comments contained in the report should be incorporated into the site development plans
and made conditions for permit issuance.
Adequate erosion and sediment control features need to be implemented during land disturbing
activities to protect neighboring properties and State waters from adverse stormwater runoff
impacts. The migration or release of silty water or mud from the applicant's property will be
considered a violation of County and State water quality protection regulations.
Please feel free to contact me at 724 if you have any questions regarding these comments, or if
you feel any features need further discussion or attention.
Sincerely,
John Stiva

IN PRODUCTION
The subject property is located in a rolling hill section of Mason County located approximately 4-
✓/2 miles south and west of Shelton at the NV corner of the.Shelton `alley Road and the
Cloquallum Road intersection. The property is approximately 5 acres in area and is generally
rectangular with boundary dimensions of roughly 330 x 660-feet.
The Girardins wish to replace a portion of, and expand the single family residence on the
property. A site plan is attached.
An initial inspection of the property revealed two main slopes on the property. One slope is a
fairly ancient fill slope which runs across the property from east to west, whose crest is
approximately 40-feet from the proposed residential foundation. This slope varies in height,
but generally is from 5 to 8+ feet tall and is standing at an approximate 2:1 slope. The second
slope on the property is more substantial,and is located north of the existing residence
approximately 70f feet, This slope was measured at 39°f%overall,with small local areas
slightly steeper. The height of this slope was estimated at 40 to 60 feet where it terminates on
the property located north of the CI irardin property at an access road constructed to serve a
neighboring residence. The slope lessens as you proceed north from the neighboring
property. I hough a geotechnical assessment could be claimed to be sufficient, this report will
attempt to address the issues that might be considered of importance in a georeport.
The following ten elements are required by Mason.County to be addressed in geotechnical
reports prepared to comply with Mason County's Critical Resource Ordinance Sections
17,01;l 00 through 17.111.104
1. SlSURFACE AND GEOLOGIC CONDlTIO S:
The property has been logged in the past, and for the most part lies in a"pasture" condition.
The northerly portion of the property is forested with fir, cedar and hemlock trees,and a

moderate understory of salal, Oregon grape, ferns, and other vegetation. The Series 1950,
No. 9 SOIL SURVEY of Mason County,plate#23, indicates the site soils are a Grove
Sandy Loam(Gk)usually found on 5-15 percent slopes. The area surrounding the property is
shown to include a Wadell Loam soil (Wa). Soils onsite appear to be more of the Wadell
character then the Grove series soil, at least at shallow depths. The Wadell soils are reported
as having little gravel, whereas the Grove soils typically contain substantial percentages of
gravel and cobbles. Both soil types are characterized as being well, or excessively drained.
Neither the Grove or Wadell soils are considered highly erodible,and do not present too great a
challenge on this site.The proposed construction activities are well within the Girardin's
property bounds, so erosion and sediment control measures may be considered in-place, in the
form of vegetated buffers between construction activities and neighboring properties.
2. DEVELOPMENT AND GEOLOGIC FEATURES:
Very little grading will be required for the planned building expansion, mostly for new
footings, and to provided required crawlspace clearance. Material excavated for the
foundation may be wasted in the surrounding yard, or placed to enlarge the yard area
between the residence and the Cloquallum Road.Any soil wasted on-site as fill material
should only be place in areas prepared to receive fill. Preparation should include clearing
vegetation and roots from the receiving area, and if fill is to be placed on existing slopes
exceeding 20% (20-feet of rise per 100-feet of run), 6-foot or wider benches should be
excavated into the slope so that the fill may be placed in even depth lifts(< 12"deep),with
equipment compaction providing a good firm fill. No structure supporting fills are required
by the proposed building expansion.
3. LOCATIONS OF LOGS OF EXPLORATORY HOLES OR PROBES:
Slopes and cuts on the property and in the subject property's vicinity were inspected and
compared with reported soil cataloging.The shallower soils on the property conform to the
Wadell soil characteristics, while the deeper soils appear to be more of the Grove soil series
character.
4. CROSS SECTION WITH PROPOSED GRADE CHANGES:
A cross section is included in the appendix.No appreciable grade changes are anticipated to
be necessary for the addition or replacement of the residence, or preparation of the
foundation footings.
5. SLOPE STABILITY ANALYSIS:
The steeper slopes on the property contains no obvious recent mass landslides or stability
problems.For stability analysis,the soil are considered to be a loamy or gravelly sand,and a
soil density of 125 lbs/ft3 for SM or Gm will be used.36°will be used as the soil's internal
friction angle in the stability analysis. Slope stability calculations are provided in the

(360) 877-9512
Appendix.
6. RECOMMENDED SETBACKS& DRAINAGE:
The slope descending to the south between the residence and the Cloquallum Road is stable in its
present condition.The Girardins' planned house location provides a 20+foot setback between
the house and the crest of the short bank,which should be sufficient.
The Steep slope to the north of the house location also may be considered at an adequate distance
to provide a natural buffer from a potential landslide hazard. This slope,because of its greater-
height and steepness may be considered the greatest potential threat on the property.This section
was modeled in the stability analysis.
Runoff collected from around the residence and produced by the structures' downspouts may be
directed to downspout splash blocks,or dispersed into vegetation around the yard.The planned
building replacement and expansion do not appreciably alter the quantity of runoff produced by
the entire property,and constitute little change from the property's original condition prior to the
planned construction.
7. CLEARING, GRADING,AND VEGETATION MANAGEMENT:
Little or no clearing or vegetation removal will be required for the planned construction.
A volume of less than 200 cubic yards of soil/gravel is expected to be needed to be borrowed or
wasted off site to accomplish the planned building elevation leveling and other site work.
8. EROSION AND SEDIMENT CONTROL:
The construction is planned during the summer months,to take advantage of favorable weather,
and to minimize erosion and sediment control requirements.
During construction,should rain or adverse weather develop,stormwater runoff from disturbed
soils areas should be intercepted with hay bales, silt fencing, or ditches and curbs to direct silty
water to settling areas where silt can be settled out before the runoff exits the construction area.
Areas of the site where grading has been completed should be compacted with the grading
equipment, covered with straw, plastic, or hydro seeded until a permanent protective vegetative
cover has established itself.
9. ON-SITE AND OFF-SITE IMPACTS:
Construction and completion of the proposed improvements are not expected to result in any
adverse on-site,or off-site impacts.The proposed residential development of the property will
not result in adverse impacts to either the subject property or to neighboring properties.
IQ SPECIFICATIONS OF FINAL DEVELOPMENT CONDITIONS:

The completed site will be allowed to return, for the most part, to a naturally vegetated state. The
main ground cover will be lawn and medium height shrubbery.
In the future development of the property, discharging concentrations of collected
Stormwater runoff within 30 feet of a property boundary should be avoided.
Conclusions and Summary;
The residential development of the Peter and Christine sirardin property located at the
intersection of the Shelton Valley Road and the Cloquallum Road does not appear to present
any stability problems that cannot be overcome, and will not result in an y=°'undesirable
impacts.
I hope this report meets the needs of the C,irardins, and Mason County in planning the
property's development.
Sincerely,
Alan A. Tahja, P.E.

NOTIFICATION OF INCOMPLETE APPLICATION
3/31/2006 Case No.: BLD2006-00408
Comments: A site inspection was conducted on 3/29/06 to assess critical areas
relevant to future residential construction. The proposed project is
adjacent to or within 300 feet of a steep slope. This area meets the
criteria for a landslide Hazard Area per the provisions of the Mason
County Resource Ordinance NO. 7793. Applications for development
within 300 feet of a Landslide Hazard Area require a geological
assessment/geotechnical report to assess slope stability and address
specific efforts to remediate the hazard. Enclosed is a copy of the
Landslide Hazard Areas chapter of the Resource Ordinance. Please.
note the distinction between a geological assessment (Section E.4)
and a geotechnical,report (Section E.5). A geological assessment is
required for slopes between 15% and 40%, and a geotechnical report
is required for slopes greater than 40%. From measurements taken on
site, it appears that slopes are less than 40% and therefore this
proposal will require,a geological assessment. Should the
engineer/geologist identify slopes greater than 40% then a
geotechnical report will be required.
Please provide the enclosed ordinance to your licensed engineer or
geologist so that they are aware of all the requirements per Chapter
17.01.100, Section E.1-7. Missing information will result in further
delay in the processing of your building permit.
The report must state that the hazards of the landslide area can be
overcome in such a manner as to prevent harm to propertyand public
health and safety, and must also assure the project will cause no
significant environmental impact (Section E.7).
