SUBJECT: Compaction Testing
for Horse Corral Pad
Lot 252; Track 3883
Dear Mr. Ottman:
Enclosed is the fine grade compaction report for the subject
property. The report represents a summary of the observations and
compaction testing of the fill placed on the proposed grading pad. Field
testing and observations indicate the compaction of the soil was performed
properly. The soil should perform satisfactorily for the expected usage.
The included findings and recommendations have been derived in accordance
with generally accepted professional principles and practices in the
fields of soil mechanics and foundation engineering. This warranty is in
lieu of all other warranties, either expressed or implied.
The opportunity to be of continued services is sincerely appreciated.
If you should have any questions or require further information, please
contact me at your convenience.
Respectfully submitted,
Enclosure:

INTRODUCTION
In accordance with your request, tests have been performed on the fill
placed on the fine graded horse corral pad. The excavation, fill
placement, compaction and testing associated with this phase of the
grading was performed during September 13 to September 27, 1996. This
report presents a summary of the observations and testing services
provided.
PROJECT DESCRIPTION
The site will have a horse corral in the back yard of the existing
residence with associated landscaping.
GRADING PROCEDURES
The observations and test results indicated that the grading was performed
in the method consistent with the project specifications. All areas to
receive fill were striped and cleared of vegetation and soft soil prior to
placement of soil fill.
Keying and benching into natural ground was completed in general
compliance with the Uniform Building Code, Chapter 70.
The minimum acceptable degree of compaction content was 90 percent of the
maximum density.
FIELD DENSITY TESTING
Field density testing was performed in accordance with ASTM D1556-64 (Sand
Cone Method) or D-2937-71 (Drive Cylinder) test method, respectively. The
results of the field density tests are presented in Table I of this
report. The approximate location of the tests are shown on the Plot Plan,
Plate 1.

.
.
MAXIMUM DENSITY DETERMINATIONS
Maximurn density/optimum moisture determinations were made from
representative samples of on-site soils used in the fill operations. The
tests were performed in accordance with ASTM D1557-78 Method.
LIMITATIONS
The findings and recommendations of this report were prepared in
accordance with contemporary principles and practices in the field of
geotechnical engineering. No other warranty or guarantee is either
expressed or implied. Only a portion of the subsurface soils and
conditions were evaluated or observed and the conclusions are based upon
an interpretation of the soil conditions encountered in the field tests.
Conclusions are also based on the assumption that these findings do not
vary appreciably in the adjacent areas. However, minor variations may
occur: should soil conditions significantly different be encountered in
the future, an assessment of the impact on subsequent recommendations
should be made. '
All future grading and fill placement should be performed under the
inspection and testing of an engineer.
SUMMARY
Our description of grading and backfill operations, as well as
observations and testing services, were limited to those grading
operations performed during September 13 to September 27, 1996. The
conclusions and recommendations contained herein have been based upon our
observation and testing as noted. It is our opinion that the work
performed in thE' areas denoted has generally been accomplished in
accordance with U.B.C. Chapter 70 specifications. No conclusions or
warranties are made for areas not tested or observed.
This opportunity to be of service is sincerely appreciated. If you have
any questions, please call.
