Discussion
Pacoima Spreading Grounds has insufficient storage capacity, low percolation rates,
and intake restrictions during high flow conditions. The proposed spreading grounds
improvements will reconfigure the basins to provide increased storage capacity, while
removing clay to increase percolation rates.
The project consists of improving the existing intake structure by replacing the intake
canal with four 54-inch diameter reinforced concrete pipes. The area will be backfilled
to create an area for future recreational or habitat enhancement opportunities. The
radial gate will be replaced with a rubber dam. The improved intake will convey an
intake flow rate of 600 cubic feet per second (cfs) even under high flow conditions and
eliminate flooding problems at Arleta Avenue.
The recharge basins will be reconfigured and deepened. The shallow clay layer in the
upper 12 to 24 feet of the subsurface will be removed to improve percolation and

increase storage capacity. Estimated removal depths for each basin are based on
recommendations reported in the January 2009 Geological Investigation Report
completed by Geotechnical and Materials Engineering Division, but field conditions will
be used to determine the final removal limits. Approximately 1,370,000 cubic yards of
excavated material will be removed from the site. The material will be sent to the
nearby Vulcan Materials Co. processing site or trucked to an alternative location.
The proposed improvements will increase the storage capacity of the grounds from 530
to 1,197 acre-feet (AF) by deepening and combining basins. Operational efficiency will
be enhanced with the proposed interbasin structures and facility layout. The percolation
is expected to increase from 65 to 142 cfs as a result of the clay removal. The
improvements are estimated to conserve an additional 10,500 AF of water per wet year.
Department of Water and Power (DWP) has expressed an interest in improvements to
Pacoima Spreading Grounds. Upon approval of this concept we will meet with DWP to
discuss the approved concept and to explore cost sharing opportunities.
WMD and Flood Maintenance Division have reviewed the concept and we have
incorporated their comments.

PACOIMA SPREADING GROUNDS
PROJECT CONCEPT REPORT
Background
Pacoima Spreading Grounds is located in the City of Los Angeles near the intersection
of Paxton and Arleta Streets on the west side of Pacoima Diversion Channel.
The facility consists of 12 large shallow basins and has a storage capacity of
530 acre-feet (AF). The facility is one of the major water conservation facilities that
recharge the San Fernando Basin.
The water conserved at Pacoima Spreading Grounds is supplied by storm flows and
controlled releases from Pacoima Dam, partially controlled flow from Lopez Basin, and
uncontrolled flows from East Canyon and Pacoima Wash. Water is diverted from
Pacoima Wash into the spreading grounds utilizing a radial gate, and then the water
flows through the intake canal to the spreading basins.
The facility's percolation is limited due to clay-rich lenses with low permeability that
underlie the recharge area. The intake to the spreading grounds is limited to 600 cubic
feet per second (cfs) since higher flows cause the intake canal to overflow, which
causes flooding on Arleta Street. Channel flows in Pacoima Wash frequently exceed
the radial gate's limited operating capacity of 1,700 cfs. When this occurs, diversion to
the spreading grounds is suspended since the radial gate must be removed from the
channel invert, allowing water to be wasted to the ocean.
Additional maintenance and operational difficulties exist at the facility. A Department of
Water and Power (DWP) 72-inch diameter water main, runs across the lower basins
and has been previously damaged during spreading grounds maintenance activities.
Also, flow is limited to the western basins south of Devonshire Street because the
culverts cannot convey the design intake flow.
Proposed Spreading Grounds Improvements
The proposed improvements will increase the storage capacity and simplify operations
by combining basins and constructing new interbasin structures. The radial gate will be
replaced with a rubber dam that can operate during higher flows. Different options to

project:
Alternative A - Modify Existing Intake and Remove Clay
Alternative B - Build New Intake at Different Location and Remove Clay
Alternative C — No Change to Existing Intake, Remove Clay
Intake Upgrade
Modify Existing Intake — Alternative A
Alternative A consists of improving the existing intake structure by replacing the intake
canal with four 54-inch diameter reinforced concrete pipes (RCP). The area will be
backfilled to create an area for future recreational or habitat enhancement opportunities.
The radial gate will be replaced with a rubber dam. The improved intake will convey an
intake flow rate of 600 cfs and eliminate flooding at Arleta Avenue. The recharge basins
will be reconfigured and deepened.
Build New Intake at Different Location — Alternative B
Alternative B consists of constructing a new intake structure located at the southeast
corner of Arleta Avenue and Paxton Street. An air-inflatable rubber dam will be installed
in Pacoima Diversion Channel at the new location, the radial gate and old Headworks
Structure will be removed, the settling basin will be reconstructed, and recharge basins
will be reconfigured and deepened. The parcel that is proposed for the new Headworks
location is privately owned and an easement will need to be acquired, or the parcel will
need to be purchased outright.
No Change to Existing Intake — Alternative C
Alternative C consists of leaving the existing intake operational. This option would save
$1,400,000 of the capital costs but would reduce the water conservation benefit.
Percolation Improvement
Clay Removal
For both alternatives the shallow clay layer in the upper 12 to 24 feet of the subsurface

will be removed to improve percolation and increase storage capacity. Estimated
removal depths for each basin are based on recommendations reported in the
January 2009 Geological Investigation Report completed by Geotechnical and Materials
Engineering Division, but field conditions will determine the final removal depths.
Approximately 1,370,000 cubic yards (CY) of excavated material will be removed from
the site. The material will be sent to the nearby Vulcan Materials Co. processing site or
trucked to an alternative location.
Storage Improvement
Alternative A — Storage capacity will increase by approximately 667 AF.

1.0 INTRODUCTION
A subsurface investigation for determining the lateral and vertical limits of a large clayrich bed was performed for the Pacoima Spreading Grounds as requested in your
March 5, 2007, memo (Appendix A). The site consists of 12 basins and associated
levees located on approximately 150 acres southwest and northwest of the intersection
of Devonshire Street and Arleta Avenue in the communities of Arleta and Mission Hills
in the City of Los Angeles (Figure 1).
1.1 PURPOSE
The main objective of this subsurface investigation was to locate and identify the limits
of anear-surface clay-rich soil layer by drilling ten boreholes within the subject site. The
results of this investigation and our conclusions are provided in this report.
1.2 SCOPE OF SERVICES
To achieve the project objectives, the following scope of services was provided:
•
Performing site reconnaissance.
•
Reviewing selected geologic reports and maps.
•
Drilling and logging ten boreholes.
•
Preparing this report which presents our findings and conclusions.
1.3 SITE PLAN
The site map supplied by your Division consists of a scanned composite plan at the
approximate scale of 1 inch equals 120 feet. This plan was utilized during fieldwork and
the geotechnical cross-sections were prepared using this map as the base. However,
the format of this map was not conducive to computer drafting systems and is not
included in this report.
The Site Plan (Figure 2) was prepared utilizing a schematic of the Pacoima Spreading
Grounds and is presented at the approximate scale of 1 inch equals 480 feet. Owing to
the scale of the site plan, the geologic contact separating artificial fill from Quaternary
alluvium cannot be shown in the detail provided on the geologic cross sections.

In general, the levees and streets are underlain by 2 to 16 feet of artificial fill and the
basins bottoms are underlain by Quaternary alluvium.
2.0 SITE DESCRIPTION
The site is an irregularly shaped parcel that consists of approximately 150 acres located
adjacent to and southwest and northwest of the intersection of Arleta Avenue and
Devonshire Street in the Arleta and Mission Hills communities of the City of Los Angeles
in the north-central San Fernando Valley. The site is located within a portion of
Sections 15 and 16, Township 2 North, Range 15 West of the U.S. Geological Survey
San Fernando Quadrangle (7.5-Minute Series).
The site is operated by your Division as an infiltration/groundwater recharge facility.
The facility consists of 12 basins separated by a series of levees. The facility is
bounded by Arleta Avenue, Filmore Street, Woodman Avenue, residential properties,
and Devonwood Park. Devonshire Street bisects the site into northerly and southerly
sections. Service roadways within the facility are located on the levees; ramps from the
roads provide access to the basins. Other improvements onsite include aboveground
and belowground utilities that cross the central portion of the site.
The surrounding area consists of residential structures and the accompanying streets
located adjacent to the site on the north, west, southwest, and southeast. A park is
located adjacent to the west-central portion of the site and spreading ground facilities
are located offsite on the north side of Arleta Avenue. The Pacoima Diversion Canal is
located to the northeast of the site and the Pacoima Wash Channel is located to the
south of the site.
3.0 PHYSICAL SETTING
3.1 SITE CONDITIONS
The site is located in the north-central San Fernando Valley south of the San Gabriel
Mountains at elevations ranging from 948 feet to 901 feet above mean sea level.
Overall, the site slopes gently to the south; however, as the site consists of basins and
levees, the natural grades and gradients have been modified to impound water and to
move water in a controlled manner from one end of the site to the other. The basins
have been excavated below native grade and the levees have been constructed above
natural adjacent grade along the perimeter of the site. Vegetation consists of grasses
and brush in the basins and on the levees. Various trees are located on the levees
along the perimeter of the site.

3.2 GEOLOGIC SETTINGS
The site is located within the San Fernando Valley, which is an east-west trending basin
within the Transverse Ranges geologic/geomorphic province. Overtime, the basin has
subsided and been infilled with alluvial material as the mountains bounding the
valley/basin have uplifted along underlying thrust-fault systems. This portion of the
basin has infilled with sediments derived from the crystalline bedrock of the San Gabriel
Mountains and received from the Pacoima Wash and Tujunga Wash drainage systems.
The sediments include sand, silt, and gravel of granitic origin, and clays that have
formed during the weathering process.
The onsite geologic units include artificial fill (af) and Quaternary alluvium (Qal). The
artificial fill consists of sand, silt, gravel, and clay that apparently was excavated from
the basin areas and used to construct the levees. The levees vary in height from
approximately 8 feet to 16 feet above the bottoms of the adjacent basins. The
Quaternary alluvium consists of sand, silt, gravel, and clay deposited in stream channel
and/or floodplain environments.
3.3 HYDROGEOLOGIC SETTING
The site is located in the San Fernando hydrologic subarea of the upper
Los Angeles River groundwater basin. Fresh water is typically found at a depth of
several hundred feet in loose to partially consolidated, coarse to very coarse, alluvial
deposits in the eastern portion of the San Fernando hydrologic subarea.
Data for nearby wells (within two miles) provided by the State of California and the
County of Los Angeles indicate that the historic high groundwater levels in the subject
area are greater than 200 feet below the ground surface.
4.0 FIELDWORK
4.1 RECONNAISSANCE
On April 10, 2007, Geotechnical and Materials Engineering Division (GMED) performed
a site reconnaissance with contract driller, Boart Longyear, and Flood Maintenance
Division.
No concerns were observed that would significantly limit the field
investigation.

SUBSURFACE EXPLORATION
Subsurface exploration was performed from May 21 through 23, 2007. Ten borings
(B1 through B10) were drilled, utilizing a sonic drill rig provided by Boart Longyear, to
depths ranging from 27 feet to 57 feet (Summary Log of Borings are provided in
Appendix B). The approximate locations of the borings are shown on Figure 2. The
sonic drill rig drilled approximately 8-inch-diameter borings and allowed for the collection
of nearly continuous, disturbed core samples. The core samples were then inspected
and logged by GMED personnel. At the completion of drilling, each boring was
backfilled with clean, bagged Monterey Sand. Soil cuttings from each boring were
manually spread within the basin in the vicinity of each boring.
The clay-rich bed was initially observed during the 2006 Fugro West, Inc., investigation.
(References). During the 2006 study, the clay-rich bed was observed only in the
northern-most borings along the margins of the Pacoima Spreading Grounds.
Figure 2 shows the location of the Fugro West Borings. For the current investigation,
the boring locations were chosen to determine if the clay-rich bed was continuous and
extended beneath the basins. As the clay-rich bed was encountered during this study,
additional boring locations were chosen to delineate the southerly and westerly limits of
the bed.
5.0 FINDINGS
•
The alluvium observed underlying the Pacoima Spreading Grounds is
predominantly a combination of sand, silt, and gravel. Additionally, a relatively
continuous clay-rich bed was encountered in Borings B-1 through B-5, B-7, B-9,
and B-10.
•
The clay-rich bed varied in thickness from 3 feet in Boring B-10 to 10 feet in
Boring B-5. The bed appears to dip to the south-southwest and is approximately
located on the Site Plan (Figure 2) and the geologic cross sections
(Figures 3, 4, and 5). This bed appears to underlie all of Basins 1, 6 through 11,
and portions of Basins 2 through 5, and 12. The depth to the top of the clay-rich
bed, below the bottoms of the affected basins, varies from 5 to 15 feet. The
maximum anticipated depth to the bottom of the continuous clay-rich bed is
19 feet below the bottom of Basin 11.
•
Additional clay-rich beds were observed in several borings. However, these
beds appear to be significantly thinner, generally less than 3 feet thick. These
clay-rich beds were observed at widely varying depths and are anticipated to be
less continuous than the above-described clay bed.

Pape 5
Static groundwater was not observed in the 10 borings drilled for this
investigation (to a maximum depth of 51 feet below the bottom of Basin 2).
However, zones of perched groundwater were observed in Borings B-2, B-6, B-7,
and B-8 at depths ranging from 16 feet to 44.5 feet below the top of the boring.
These perched conditions generally occurred above less permeable clay-rich
zones. Groundwater levels onsite are anticipated to vary widely as a result of
recharge, precipitation, and irrigation.
6.0 CONCLUSIONS
The shallow subsurface investigation has shown that a continuous clay-rich bed
underlies much of the Pacoima Spreading Grounds. This bed is anticipated to limit the
vertical infiltration of recharge water placed in the affected basins.
Based on the perched groundwater observed in Borings B-2 and B-6 through B-8, the
thinner clay-rich beds also appear to limit the vertical infiltration of recharge water.
However, as these clay-rich beds appear to be laterally discontinuous, it is anticipated
that recharge water moves along the clay bed until a path for downward infiltration is
found. Additional clay-rich beds may exist below the depths explored during this
investigation which may yet impede infiltration rates.
Removal of the continuous clay-rich bed underlying all of Basins 1, 6 through 11, and
portions of Basins 2 through 5, and 12 and replacement with a more permeable (and
better sorted) coarse-grained material as planned by your Division, is expected to
improve the infiltration characteristics of the Pacoima Spreading Grounds.

REQUEST FOR SUBSURFACE INVESTIGATION REPORT
PCA NO. H0321129
It is requested that your division make the necessary subsurface explorations for concept
planning purposes and prepare logs and a report, which will describe the earth materials
beneath Pacoima Spreading Grounds. The logs and report should also show sampling
method used, location, identification designation, date of start and completion, name of the
logger, and drilling subcontractor.
Previously, nine drill holes were excavated as part of a geotechnical study for levee
evaluation by Fugro West, Inc. Locations of drill holes are not representative of the entire
spreading basin. Therefore, exploration of additional drill holes is necessary to identify the
limits of a large clay layer. The plan of Pacoima Spreading Grounds with existing drill hole
locations is attached for your use.
~~
This information is required no later than April 2, 2007, to enable us to meet the
established project schedule.
If you have any questions, please contact
Marine' Gaplandzhyan at 458-6170.
