GEOTECHNICAL INVESTIGATION REPORT
EAST SIDE BAPTIST CHURCH
4045 COMMERCIAL AVENUE
SPRINGFIELD, OREGON
BRANCH ENGINEERING INC. PROJECT No. 09-060
1.0 INTRODUCTION
This report presents the results and findings of Branch Engineering, Inc. (BEl) field
observations, testing, and research for the subject site. The site, located at 4045
Commercial Avenue in Springfield, Oregon is an irregular shaped parcel. The site is in
Section 31 of Township 17 South, Range 2 West of the Willamette Meridian. The site is
currently occupied by two, single-story, wood-frame buildings configured into a "L"-
shape, paved parking facilities, and a fenced baseball diamond.
The purpose of our investigation was to evaluate subsurface soil and geologic
conditions at the site and provide geotechnical recommendations for the design and
construction of the proposed site development.
1.1 Project and Site Description
The proposed project consists of constructing a two-story, steel rigid-frame sanctuary
building with a footprint of approximately 11,500 square feet and associated new
parking area of about 102 spaces. The expected building column and wall loads are
not expected to exceed 50 kips and 4 kif, respectively. The floor of the building is
expected to be concrete slab-on-grade.
Other than the existing buildings and parking areas, the majority of the approximately
four acre site is covered with mowed grass with few trees. A developed baseball
diamond with a fenced perimeter and dugouts is located in the approximate center of
the property. The site is relatively flat and the site can be accessed from either
Commercial Avenue or 41st Street. It is our understanding that the southwest corner of
the existing building experienced about four inches of settlement and was releveled in
2008 using helical piers installed to depths of 8- to 13-feet. An area of isofated soft fill
material was detected off the corner of the existing building as indicated by Boring 3
summary log, which likely explains the cause of the settlement. No other fill material
was encountered in our site borings. The initial site building on the north side was
constructed sometime between 1952 and 1960 with the second building added before
1968.

1.2 Scope of Work
Our scope of work included a site visit on April 9, 2009 to observe site conditions and to
direct and log the advancement of five (5) exploratory borings to depths of 10- and 15-
feet below the existing ground surface. Field log summaries are presented in Appendix
A, along with copies of nearby well logs from the Oregon Department of Water
Resources on-line database and on-line soil survey information.
The depth of the borings were advanced using a Model 6600 truck-mounted Geoprobe
hydraulic boring machine to collect near continuous, 1.5-inch diameter subsurface
samples. Representative samples were collected for additional visual inspection and
laboratory in-situ moisture determination and shrink/swell potential.
The test pit soil stratigraphy was visually classified in accordance with the American
Society of Testing and Materials (ASTM) Method 0-2488. In-situ field testing consisted
of pocket penetrometer readings to assess unconfined compressive strength of the fine-
grain soils, vane shear testing, dry strength and dilatency testing.
1.3 Site Information Resources
The following site investigation activities were performed and literature resources were
reviewed for pertinent site information:
. Review of the United States Department of the Interior Geological Survey
(USGS) on-line Quadrangle Map, 7/1/1986.
· Review of University of Oregon aerial photographs from 1936 to 2000.
. Five exploratory borings were advanced on site at the approximate locations
shown on Figure 1.
. Review of the Lane County area Web Soil Survey, United States Department of
Agricultural (USDA) Natural Resources Conservation Service (NRCS)
. Review of the USGS Geologic Map of Oregon, USGS 1991

3.0 SITE SUBSURFACE CONDITIONS
The near surface soils within the project area consist of Pleistocene age unconsolidated
to semi-consolidated alluvial terrace deposits of clay, silt, sand and gravel from
lacustrine and fluvial environments. The NRCS Web Soil Survey maps the east side of
the site as part of the Oxley-Urban land complex and the west side as Awbrig-Urban
land complex, both of which are described as poorly drained silty clay loam with gravel
in the Oxley complex.
The site borings indicate silty clay overlying dense sandy gravel deposits commonly
referred to as "Bar-Run" material at depths between 2.5- and 8-feet below the ground
surface. The fine-grain alluvial soils are generally moist to very moist, soft in the upper
1- to 2-feet grading to stiff. The sandy gravel deposit, Bar-Run, is moist and dense.
Based on nearby well logs, the Bar-Run is generally encountered with the upper 20 feet
of the surface and extends to depths of over 50 feet. .
3.1 Ground Water
A static ground water level was encountered between 4.5- and 6-feet below the ground
surface in those borings within the building site. Nearby well logs indicate a static
ground water levels between 9 and 17 feet below ground surface. The water level
below the site will be influenced by seasonal precipitation changes and the water level
of the McKenzie River located less than 1 mile north of the site. Ground water is not
anticipated to adversely affect the proposed site development; however, some utility
trench dewatering may be required.
4.0 GEOLOGIC SETTING
The following sections described the regional and local site geology. Our field findings
are consistent with the geologic mapping of the site area by the Oregon Department of
Geology and Mineral Industries (Walker & MacLeod, 1991).
4.1 Regional Geology
The subject site lies within the southern portion of the Willamette Valley Geomorphic
Province (WVGP), east of the Coast Range and west of the Cascade Mountains
Provinces. The WVGP is a regional lowland that extends from just south of Eugene,
Oregon to Vancouver, British Columbia. In Oregon, this alluvial plain is approximately
130 miles long and 20- to 40-miles wide (Orr and Orr, 1996). The WVGP is drained by
the north flowing Willamette River. The bedrock of the Willamette River Valley in the
area of the subject site is believed to be part of the Fisher-Eugene Formations that are

described as marine sedimentary rocks from the Oligocene and Eocene epochs
(approximately 35 million years ago). Deposits of silt and clay from fluvial and
lacustrine environments covered the bedrock to various depths during the presence of
low energy streams and lakes in the southern Willamette Valley. Compression forces,
along with uplifting of the Cascade and Coast Range Mountains, during the Miocene
and Pliocene epochs depressed the Willamette River Valley and caused gentle folding
of the Fisher-Eugene Formations. The rapid uplift of the Cascade and Coast Range
mountains steepened stream gradients causing increased erosion of the mountains and
resulting deposition of thick gravel layers incised within the fluvial and lacustrine
deposits. Approximately 13,500 years ago the Willamette Valley was cyclically flooded
by catastrophic breaks in the ice dams of Lake Missoula. These flood events filled the
valley to a depth of about 350 feet before retreating, causing sequences of upward
fining deposits of silt and clay.
4.2 Site Geology
The observed site conditions are consistent with the mapped geology of the site and
that of the general geologic setting described above. Silt and clay overlay sand zones
atop the gravel Bar-Run material that that may contain cobbles to 8 inches in diameter.
The Bar-Run in this area has a matrix of sand and silt. The gravel/cobbles are
anticipated to extend to a depth over 100 feet with bedrock being several hundred feet
below ground surface.
5.0 CONCLUSIONS
Based on our field observations, subsurface explorations, and data analyses, we
conclude that the site is geotechnically suitable for the proposed development provided
that the recommendations of the report are incorporated into the design and
construction of the project.
The primary impedance to site development will be the removal of the upper 1- to 2-feet
of soft, silty clay soil to expose a firm foundation subgrade.
5.1 Seismic Design
Based on our site reconnaissance, subsurface observations, review of nearby well logs,
and our general knowledge of the site geology, the potential site hazards resulting from
a seismic event are negligible. The site topography is flat; therefore, there is no hazard
from slope instability or lateral spreading since there are no mapped fault lines within
the vicinity of the site. Although not specifically encountered in our investigation, the
presence of saturated sand lenses below the site is likely; however, the potential for
adverse impacts to site development due to liquefaction occurring is negligible because

the sand lenses would be at a depth greater than 5 feet below surface grade and are
likely in a dense condition.
6.0 RECOMMENDATIONS
The following sections present general recommendations for site preparation and
grading, drainage, foundations, pavement design, and utility excavations. ~
Site Preparation and Earthwork
The following recommendations are for earthwork in the building pad area. Specific
recommendations for roadway subgrade and base rock sections are provided in the
subsequent Pavement Design section of this report.
Earthwork shall be performed in general accordance with the standard of practice as
generally described in Appendix J of the 2007 International Building Code. All areas of
fill intended to directly or laterally support structures or road/parking areas shall be
stripped of vegetation, organic soil, undocumented fill, or other deleterious material.
These strippings shall either be removed from the site or used in nonstructural areas.
The Geotechnical Engineer shall observe and approve subgrade soils prior to placing
fills, base rock, or foundation forms. Areas of fill placement will require excavation of
the surface topsoil to a depth of about 24-inches below existing surface grade.
Additional excavation may be required in areas to remove debris or minor fill from site
leveling. Should soft areas or areas of distinct soil color variation be discovered, this
office shall be notified to perform site observation.
Imported material is expected to comprise site fills, if constructed. BEl recommends
the use of nonexpansive, granular material for structural fill areas. On site or imported
fine-grain soil may be used for fill with approval from the Geotechnical Engineer prior to
delivery to the site. Soil fill may require moisture conditioning (drying or addition of
water), specific compaction equipment, and field observation and testing to achieve the
required compaction standard herein. All material shall be approved by the
Geotechnical Engineer prior to delivery to the site. Should soil fill be used, it is
recommended that the site be graded so that all building pad areas are underlain with at
least 24-inches of consistent material type, whether it is structural fill or native material.
The native soils have a moderate shrink/swell potential, therefore, it is recommended
that the upper 8-inches of all building pads be comprised of compacted 3/4" or 1"-0
crushed aggregate to mitigate soil moisture fluctuations.
If on site soil is used for fill, it is recommended that work be performed during the dry
season when site soil moisture content is more easily controlled for compaction.
Currently, the native soils appear to be 6% to 18% over optimum moisture content.

Native soil shall be compacted to at least 90% of the material's maximum dry density as
determined by ASTM Method D-1557. The fine grain soils are moisture sensitive and
will soften with exposure to prolonged rainfall. It is recommended that earthwork be
performed during the dry season, generally May through October. Should earthwork be
conducted during the wet season, additional project costs will likely be incurred, such as
additional soil excavation, use of geotextiles or soil amendments for subgrade support,
and moisture control of the fill materials. An option is to use imported fill material, within
8-inches of the final grade, consisting of 3"-0 crushed, well graded rock with less than
10% of the material passing the No. 200 sieve. The 3"-0 rock shall be capped with at
least 8-inches of 3/4" or 1"-0 crushed aggregate. All imported granular material shall
be compacted to at least 95% of the material's maximum dry density as determined by
ASTM Method D-1557, and tested to measure compliance. Granular fill materials not
suitable for standard field density testing shall be proof-rolled every 12-inches in
thickness with a loaded 10 cubic yard dump-truck or equivalent piece of equipment.
Fill/Cut Slopes
Although not anticipated, and fill and/or cut slopes shall be constructed no steeper than
2:1 (horizontal:vertical) and shall be compacted to their outer edge by either back rolling
or being over built and cut to grade. All slopes shall be protected with erosion control
measures and surface water shall not be allowed to drain over the top of a slope.
Foundations shall be placed such that there is at least 5 lateral feet from the face of
slope or outside a 1:1 plane projected from the toe of slope, whichever is greater.
Excavations
Utility excavations in the fine grain soils should stand near vertical up to 4 feet in depth.
These soils may be classified as OSHA Type A Excavations into the expected
underlying sand/gravel zone will be prone to caving and are designated as an OSHA
Type B soil.
Drainage
A complete site drainage system is expected to be engineered; drainage from and onto
adjacent properties should be considered in the design, particularly if existing elevations
are altered. Foundations constructed below grade may require footing drains and shall
be determined in the field.
On-site disposal of storm water runoff may be feasible; however, site infiltration testing
was not included in our work scope. The near surface fine grain soils are expected to
have a low rate of infiltration, which should increase near the Bar-Run.

Soil Bearing Capacity
Based on the site observations, conventional spread footings are expected to be
constructed for the proposed site building. After conformance with the subgrade
preparation recommendations herein, foundation areas shall be covered with a
separation fabric (woven geotextile meeting AASHTO M288-00 or equivalent) and at
least 8-inches compacted crushed aggregate. The fabric and aggregate cap shall
extend at least 12-inches beyond all sides of the footings. The aggregate shall consist
of a crushed 1.5"-0 or 3/4"-0 aggregate compacted to at least 95% of the material's
maximum dry density at determined by ASTM Method 0-1557.
The allowable soil bearing capacity of the soil subgrade at least 2-feet below existing
surface grade and prepared as described herein is 1,500 psf, and may be increased
500 psffor short-term wind and seismic loading. The coefficient of friction for concrete
poured neat against native soil is 0.35 and 0.50 for crushed aggregate layers at least 8-
inches thick. Perimeter landscape grades shall be sloped away from all foundations
and water should not be allowed to pond near footings.
The following recommendations shall be implemented in the design and construction of
the project. Periodic site observations by a geotechnical representative of BEl is
recommended during the construction of the project; the specific phases of construction
that should be observed are:

Slab-On-Grade
The subgrade areas to be overlain by load bearing concrete slabs shall be prepared as
described for foundation areas except that the slabs shall be underlain by at least 12-
inches of compacted crushed aggregate. The concrete slabs shall be designed using a
modulus of subgrade reaction (k) of 150 Ib/in3. The use of a vapor barrier below
interior concrete slabs is at the discretion of the designer, and generally based on the
,use of the room above the slab andlor the floor covering material.
Settlement
Specific building foundation loading was not available at the time of this report, but
loads are not expected to exceed 3 kif for walls loads or 50 kips for column loads. Site
specific consolidation testing was not performed; however, based on field testing and
observations, the estimated total settlement is not expected to exceed 3/4-inch and
differential settlement is not expected to exceed 1/2-inch over spans of 20 feet. A
portion of the settlement is expected to occur during the construction phase of the
project; however, due to the fine-grain soils below the site settlement will occur over a
longer time period as pore water migrates due to additional loading on the soil.
Pavement Design
The parking lot area and driveway are expected to be generally subjected to light
vehicle traffic; however, the following design considers occasional equipment delivery
and service vehicles, as well as emergency vehicles up to 80,000 pounds. Based on
this criteria and a 20-year design life with a 75% reliability, and incorporating the 2003
revised Asphalt Pavement Design Guide (Asphalt Pavement Association of Oregon)
and AASHTO design methods, BEl recommends a nominal thickness of 3 inches of
asphalt concrete over 8 inches of crushed aqqreqate in parkinq areas and 3.5 inches of
asphalt concrete over 10 inches of crushed aqqreqate in driveways. The crushed
aggregate base shall be compacted to 95% of the materials maximum dry density as
determined by ASTM Method D 1557. A woven geotextile separation fabric, meeting
AASHTO M288-00 or equivalent, shall be placed between soil subgrade and the base
aggregate. The geotextile fabric may be waived and the base rock thickness reduced
should subgrade excavation reveal bar-run material. Such a decision shall be made by
the field engineer at the time of excavation activities.
