For passive earth pressure to develop, wall must move horizontally to mobilize
resistance.
Level backfill is assumed. Contact Terracon for additional guidance if the wall
backfill is sloped more than 1V:5H.
Uniform area surcharge behind the wall, where S is surcharge pressure in psf.
Other surcharge loads should be considered where they are located within a
horizontal distance behind the wall equal to 1.5 times the height of the wall.
Surcharge stresses due to point loads, line loads, and those of limited extent, such
as compaction equipment, should be evaluated in accordance with Article 3.11.6
of the AASHTO LRFD specifications.
To account for the effect of compaction equipment on the wall during construction,
the lateral surcharge pressure should not be less than 100 psf, distributed
uniformly over the height of the wall.
Retained soil total unit weight up to 125 pcf.
Wall is constructed with a minimum 2-foot wide drainage layer of Crushed Stone
placed directly behind the walls, with a drain.
Backfill compacted to at least 95 percent maximum dry density (ASTM D1557)
Within 4 feet of back of wall, hand operated equipment should be used.
Loading from heavy compaction equipment not included; heavy equipment should
not operate within a distance closer than the exposed height of retaining walls.
Hydrostatic pressures acting on wall should be taken into account as appropriate.
Retaining structures should be backfilled evenly to the extent practical. Temporary
bracing should be specified if walls, that are designed to be supported by other
structural elements, are permitted to be backfilled before the permanent support
is in place.
No dynamic loading.
Passive pressure should be ignored because of the amount of movement required
to mobilize resistance.
Subsurface Drainage for Below Grade Walls
A perforated rigid plastic drain line installed behind the base of walls, which extend below adjacent
grade is recommended to prevent hydrostatic loading on the walls. The invert of a drain line
around the retaining wall should be placed near foundation bearing level. The drain line should
be sloped to provide positive gravity drainage to daylight. The drain line should be surrounded by
Crushed Stone encapsulated in a filter fabric.
Temporary Excavation Support and Cofferdam
The above parameters are not applicable to the design of temporary excavation support or
cofferdam systems for the project. For soils consistent with those encountered in our explorations,

the design of excavation support and cofferdams may be based on the following parameters.
Explorations have not been advanced at the location of the proposed pier. We recommend
explorations be advanced prior to final design of pier foundations and the cofferdams.

GENERAL COMMENTS
Our work is conducted with the understanding of the project as described in the proposal, and will
incorporate collaboration with the design team as we complete our services to verify assumptions.
Revision of our understanding to reflect actual conditions important to our work will be based on
these verifications and will be reflected in the final report. The design team should collaborate with
Terracon to confirm these assumptions and to prepare the final design plans and specifications.
This facilitates the incorporation of our opinions related to implementation of our geotechnical
recommendations. Any information conveyed prior to the final report is for informational purposes
only and should not be considered or used for decision-making purposes.
Our analysis and opinions are based upon our understanding of the geotechnical conditions in
the area, the data obtained from our site exploration and from our understanding of the project.
Variations will occur between exploration point locations, across the site, or due to the modifying
effects of construction or weather. The nature and extent of such variations may not become
evident until during or after construction. Terracon should be retained as the Geotechnical
Engineer, where noted in the final report, to provide observation and testing services during
grading, excavation, foundation construction and other earth-related construction phases of the
project. If variations appear, we can provide further evaluation and supplemental
recommendations. If variations are noted in the absence of our observation and testing services
on-site, we should be immediately notified so that we can provide evaluation and supplemental
recommendations.

Our scope of services does not include either specifically or by implication any environmental or
biological (e.g., mold, fungi, bacteria) assessment of the site or identification or prevention of
pollutants, hazardous materials or conditions. If the owner is concerned about the potential for
such contamination or pollution, other studies should be undertaken.
Our services and any correspondence are intended for the sole benefit and exclusive use of our
client for specific application to the project discussed and are accomplished in accordance with
generally accepted geotechnical engineering practices with no third party beneficiaries intended.
Any third party access to services or correspondence is solely for information purposes only.
Reliance upon the services and any work product is limited to our client, and is not intended for
third parties. Any use or reliance of the provided information by third parties is done solely at their
own risk. No warranties, either express or implied, are intended or made.
Site characteristics as provided are for design purposes and not to estimate excavation cost. Any
use of our report in that regard is done at the sole risk of the excavating cost estimator as there
may be variations on the site that are not apparent in the data that could significantly impact
excavation cost. Any parties charged with estimating excavation costs should seek their own site
characterization for specific purposes to obtain the specific level of detail necessary for costing.
Site safety, and cost estimating including, excavation support, and dewatering
requirements/design are the responsibility of others. If changes in the nature, design, or location
of the project are planned, our conclusions and recommendations shall not be considered valid
unless we review the changes and either verify or modify our conclusions in writing.

EXPLORATION AND TESTING PROCEDURES
Field Exploration
Number of Borings Boring Depth (feet) Planned Location
3 43 to 79.4 Bridge abutments
Boring Layout: The boring layout was performed by others.
Subsurface Exploration Procedures: Nature’s Way Environmental Consultants and
Contractors, Inc. performed the soil subsurface explorations. The borings were drilled with a rotary
drilling rig using continuous flight, hollow-stemmed augers to advance the boreholes. Samples
were obtained using split-barrel sampling procedures. In the split-barrel sampling procedure, a
standard 2-inch O.D. split-barrel sampling spoon is driven into the ground with a 140-pound
hammer falling a distance of 30 inches.
Laboratory Testing
The project engineer reviewed the field data and assigned various laboratory tests to better
understand the engineering properties of the various soil strata as necessary for this project.
Procedural standards noted below are for reference to methodology in general. In some cases,
variations to methods are applied because of local practice or professional judgment. Standards
noted below include reference to other, related standards. Such references are not necessarily
applicable to describe the specific test performed.
■ ASTM D2216 Standard Test Methods for Laboratory Determination of Water (Moisture)
Content of Soil and Rock by Mass
■ ASTM D4318 Standard Test Methods for Liquid Limit, Plastic Limit, and Plasticity Index of
Soils
■ ASTM D422 Standard Test Method for Particle-Size Analysis of Soils
The laboratory testing program often includes examination of soil samples by an engineer. Based
on the material’s texture and plasticity, we describe and classify the soil samples in accordance
with the Unified Soil Classification System. The results of the laboratory testing are included in
the Appendix of this report.

graded gravel with silt, GP-GC poorly graded gravel with clay. D Sands with 5 to 12% fines require dual symbols: SW-SM well-graded

H If fines are organic, add “with organic fines” to group name. I If soil contains 15% gravel, add “with gravel” to group name. J If Atterberg limits plot in shaded area, soil is a CL-ML, silty clay. K If soil contains 15 to 29% plus No. 200, add “with sand” or “with
gravel,” whichever is predominant. L If soil contains 30% plus No. 200 predominantly sand, add “sandy”
