INTRODUCTION
PropOSed Development
It is our understanding that subject site will be utilized for the construction of a single-family
residence that will utilize the septic tankIleach line method of sewage disposal.
Site Description
The subject site consists of a rectangular-shaped parcel of land located on the south side of Jedediah
Srnith Road, south of Pescado Drive in the city of Temecula in southwest Riverside County,
California The subject parcel is bordered on all sides by large parcel residential development. The
geographical relationships of the site and surrounding area are shown on our Site Location Map,
Figure 1.
Topographically, the areas proposed for the disposal systems consist of moderately sloping terrain
with a natural gradient of less than 15% to the northwest. Drainage on-site is accomplished by
sheet flow to. the northwest toward Jedediah Smith Road and the moderately incised drainage
course. Vegetation in the area of the proposed disposal system consists of a low growth of annual
weeds and grasses.
SITE INVESTIGATION
Back2round Research and Literature Review
Several published reports and geologic maps were reviewed for the purpose of preparing this report.
A complete list of the publications and geologic maps reviewed for this investigation is presented in
Appendix A.
Field Invesfu!ation
Subsurface exploration of the site, field reconnaissance, and mapping of the site were conducted on
January 25, 2003. One deep exploratory trench was excavated in the vicinity of the proposed leach
fields to a maximum depth of l5.0-ft below the existing ground surface (bgs). A total of four
shallow test pits were also excavated to various depths ranging from 36 to 48-inches below the
existing ground surface. A Case No. 580L rubber tire extenda-backhoe equipped with a 2-ft bucket
was used to excavate the exploratory trench and shallow test pits. Our geologist logged the
exploratory trench. A copy of our Trench Log is presented in Appendix B.
SUMMARY OF TEST PROCEDURES
Percolation testing was performed on January 31, 2003. The testing procedure was performed in
accordance with Riverside County Health Department and Building and Safety guidelines. The

percolation tests were performed at depths within the underlying soils corresponding to the proposed
leach field design.
At the bottom of each shallow test pit, a post-hole digger was used to excavate a 6-inch diameter, 13-
inch deep, cylindrical hole. A perforated cylinder was then placed within the test holes to prevent
caving of the sidewalls and scouring of the bottom when water was added. The holes were then
tested in accordance with the June 1988, Riverside County Continuous Pre-Soak Percolation Testing
Procedure for same day testing. Below is a detailed description of the testing procedures followed:
"After excavation of the test hole, a completely filled 5-gallon bottle of water was inverted
over the test hole so that a continuous level of water was maintained up to a height of 12
inches above the bottom of the hole. When the 5 gallons of ware,r had completely percolated
within the test hole, the empty bottle was removed and the hole was refilled to 8 inches above
the bottom. The next day testing procedure (15-26 hours after initiating pre-soak) was
utilized. A minimum of two consecutive measurements were then taken at timed intervals
that provided not less than 1 inch or more than 3 inches of drop. All measurements were
taken to the nearest lI8 inch, and the difference between the last two measurements did not
vary by more than 20 percent"
SUMMARY OF FINDINGS
Our exploratory excavation generally exposed 5-ft of recent alluvial soils overlying sedimentary
bedrock of the late-Pleistocene Pauba Formation to the maximum depth explored of 15.0-ft bgs. The
alluvial soils consisted predominately of silty sand (Unified Soil Classification-SM) that can be
described as dark grayish brown, fine to coarse grained, dry (top 2-ft) to slightly moist, moderately to
well graded with abundant pinpoint pores, worm burrows, and fine roots. Sedimentary bedrock of
the Pauba Formation generally consists of a yellow brown to dark brown silty sand (SM) that can be
described as fine to coarse grained, very silty, dense, and slightly moist. No mottling of the soil was
observed.
Percolation rates for the subject site were generally slow and varied from 48 (P-2) to 60 minutes-per-
inch (P-I & P-3).
GROUNDWATER
Groundwater was not encountered within our exploratory trench (T-l), which was advanced to the
total depth explored of l5.0-ft bgs. No mottling, often indicative of past high groundwater, was
observed within our exploratory trench. Historic high groundwater in the vicinity of the subject site
is at least 80-ft. below the ground surface (Rancho California Water District, 1984).
PERCOLATION TESTING
A total of four shallow percolation tests were performed on the subject site. A summary of our
percolation test results is provided in Table l. Copies of the field percolation test data are included

CONCLUSIONS AND RECOMMENDATIONS
ConclWlions
. Based upon the results of this investigation, on-site sewage disposal, utilizing the septic
tankIleach line method of disposal, is feasible for the subject parcels provided the specific
design recommendations of the report are implemented during site development.
. All earth materials encountered during our investigation were excavated with moderate ease
to the maximum depth explored of l5.0-ft below the ground surface utilizing a Case No.
580L rubber tire extenda-backhoe equipped with a 2-ft bucket.
. Our exploratory excavation (T-I) generally exposed 5-ft of recent alluvial soils overlying
sedimentary bedrock of the late-Pleistocene Pauba Formation to the maximum depth
explored of l5.0-ft bgs. Both the alluvial soils and sedimentary bedrock generally consisted
of silty sands (SM).
. Based on the size of the subject parcel and the proposed development design, there is
sufficient area to allow installation of an adequate on-site leach line disposal system and
100% expansion area
. Groundwater was not encountered within our exploratory trench to the maximum depth
explored of l6.0-ft bgs. Based on the data presented in the report, it is the judgment of this

firm that the groundwater table wiD not encroach within the current allowable limit (5-
ft) set forth by county and state requirements.
Recommendations
. Based on the test data obtained, a conservative percolation rate of 60 minuteslinch should be
used as the design rate for the subject site. This corresponds to an application rate of 120
square feet of leaching area per 100 gallons of effluent per day.
. Based on utilizing a 1,000-gallon septic tank (3-hdnn house) and an application rate of 120
square feet of leaching area per 100-gallons of effluent per day; 1,200 square feet of bottom
area would be required. This would correspond to 400 linear feet of leach line 3-ft wide or 4
leach lines 100-ft long. Due to the gently sloping nature (< 20% gradient) of the proposed
leach line areas, an overburden factor will not be required. As an option, we recommend
utilizing 3-ft of gravel below the rock and paper. This would reduce the linear feet of leach
line to 240-ft. This would require 3 leach lines 80-ft in length.
. Based on utilizing a 1,200-gallon septic tank (4-hdnn house) and an application rate of 120
square feet of leaching area per loo-gallons of effluent per day; 1,440 square feet of bottom
area would be required. This would correspond to 480 linear feet of leach line 3-ft wide or 5
leach lines 96-ft long. Due to the relatively flat nature (< 20010 gradient) of the proposed leach
line areas, an overburden factor will not be required. As an option, we recommend utilizing
3-ft of gravel below the rock and paper. This would reduce the linear feet of leach line to
288-ft. This would require 3 leach lines 96-ft in length.
. Based on utilizing a 1,500-gallon septic tank (5 or 6-hdnn house) and an application rate of
120 square feet of leaching area per loo-gallons of effluent per day; 1,800 square feet of
bottom area would be required. This would correspond to 600 linear feet of leach line 3-ft
wide or 6 leach lines 100-ft long. Due to the relatively flat nature (< 20% gradient) of the
proposed leach line areas, an overburden factor will not be required. As an option, we
recommend utilizing 3-ft of gravel below the rock and paper. This would reduce the linear
feet ofleach line to 360-ft. This would require 4 leach lines 90-ft in length.
. Sufficient area should be set aside on the subject site for installation of the septic system and
100% expansion. The project civil engineer should layout the system once site development
plans are available. The areas tested are depicted on Plate 1. This area must remain as
natural ground with less than I foot of cut or fill. Once site development plans are known,
additional testing may be required in the proposed leach line area to confirm our preliminary
findings.
. There must be a minimum 100-ft separation between the leach lines and expansion area to
any proposed on-site water supply well and a minimum 5-ft separation from anyon-site
domestic water line.

. The septic system shall be installed in natural, undisturbed soil at the depth of the tests
performed.
. No swimming pools or other appurtenances shall be constructed without the Riverside
County Heath Department approval.
. The systems should be installed in accordance with current UPC codes. A typical
construction approach for leach line systems is presented on Figures 2 and 2A.
. Installation of the leach lines should be inspected by the soils engineer and/or geologist to
verify that anticipated field conditions exist and that the installation is in accordance with the
recommendations of this report. A minimum 24-hours' notice should be provided for field
inspection of the leach lines.
