INTRODUCTION
Water for the City of Lodi is taken from the local ground water supply.
On the east side of the city, two existing wells are no longer serviceable
grid require replacement to supply current users. In addition, two new
wells with a combined capacity of 4,000 gallons per minute (gpm) will be
required in the near future to alleviate peak summertime shortages and
support planned development. The objective of this study is to identify
the best water well site locations on the east side of the city.
The area being evaluated for new well locations is east of the Central
California Traction Company railroad tracks; bounded by Kettleman Lane
to the south and the Mokelumne River to the north. A legal restriction j
on the city specifies the westernmost boundary of any new well siting as I
i
the north -south section line which is coincident with the western edge
of the railroad right-of-way. To verify that the new well locations will
have the least possible impact on local property owners, the area I
extending 1,000 feet west of the tracks was also considered in the study.
Selection of the best sites for the new wells is based upon a three step
approach. First, the study area is evaluated through a graphic
technique using a series of overlying plates to depict the intensity of
the effect of each site criteria upon proposed well locations. The
variations of effect for each criterion are depicted as a color shading
from light to dark, from little or no impact to infeasible.
representing
R38cc1 -1-
The completed composite figure depicts the most feasible sites as white
and the least feasible sites as a dark shade with sites of intermediate
potential shaded accordingly. Second, the technical aspects of ground
water hydrology and existing water distribution system conveyance
capacity were evaluated to establish technical criteria for final site
selection. Third, the candidate sites were inspected to evaluate access
for construction and maintenance and to minimize adverse impacts to the
affected parcels.
SITE CRITERIA
Five site criteria -issues were identified to be used in the 'first step of
the analysis. The issues and a summary of the evaluation impact are
shown in Table 1. Figures depicting the impact of each criteria follow
the report text.
EXISTING FACILITIES
Overlay No. 1, shown on Figure 1, represents the impact of existing
structures and property boundaries on the selection of well sites. This
figure includes the area to the west of the tracks to fully evaluate the
potential impact on local residences.
Existing structures, located from aerial photographs supplied by the
County's Planning Department, are shown as dark. Setbacks of 100 feet
around each structure are shaded 75 percent. In addition, parcels with
an area of 1.0 acre or less are shaded 75 percent. These lots are
considered to be significantly impacted by placement of a well upon the
property. Other improvements, such as roads, are also shaded 75 per-
cent. The remaining areas, left white, represent available locations
least impacted by the areal properties of a new well.

EXISTING WELLS
Overlay No. 2, shown on Figure 2, represents the impact of existing
wells on the selection of new well sites. This figure also includes the
area to the west of the tracks to identify potential interference with
local wells.
A well survey questionnaire, sent by the city to all property owners in
the study area, provided information on well location, depth, and_ use
(irrigation, domestic, commercial). Of the property owners who were
sent questionnaires, approximately 51 percent responded. A sample
questionnaire is shown in Appendix B. Existing wells are ! +aded dark
and their usage is denoted by symbol. The area around an existing well
in which the location of a new well may affect the yield of the existing
well is shaded 75 percent. This zone influence is used for screening
purposes to eliminr`i hydraulic interference considerations. This zone is
not intended as ai, accurate study of existing well drawdowns but. is an
approximation for screening only.
LAND USE
Overlay No. 3, shown on Figure 3, represents planned land use in the
study area.
The stud, area consists of light manufacturing and agricultural zoning.
Placement of a well in property zoned light manufacturing is considered
to be of greater financial impact than within agricultural zoning and is
shaded 25 percent. All agricultural areas are considered equal under
the criterion of impact upon land use and are white.

WATER LINES
Overlay No. 4, shown on Figure 4, consists of the proximity of a new
well site to the existing water distribution system and proposed future
distribution system conditions.
This overlay represents the economic impact of placing a well at a range
of distances from existing and future water mains. The study area is
depicted in increasingly darker shades as the location becomes increasingly
distant from water mains. Construction costs of installing a 12 -inch water
line from a new well to the existing distribution system is estimated to
be $30 to $45 per foot. A distance of 0 to 100 feet is the most economi-
cally desirable and is white. A distance of 100 to 500 feet has a
significant but manageable economic impact and is shaded 12.5 percent.
Over 500 feet is economically undesirable and is shaded 25 percent.
POWER LINES
Overlay No. 5, shown on Figure 5, consists of the proximity of a new
well site to existing 12 and 21 kV power lines.
This overlay represents the economic impact of placing a well at a range
of distances from available power. The study area is depicted in
increasing darker shades as location becomes increasingly distant from
power. Within 100 feet of either 12 or 21 kV PGandE power, hookup is
at no cost and is accordingly white. Beyond 100 feet, costs are
estimated on a dollar per foot basis. Assuming each well site produces
2,000 gallons per minute, power capital costs are estimated to be $30 to
$75 per foot. From 100 to 500 feet, power installation costs are
significant but reasonable and the areas are shaded 12.5 percent.
Beyond 500 feet, power installation costs are considered significantly
more expensive and are shaded 25 percent.

TECHNICAL CONSIDERATIONS
Once the most desirable sites were identifed based upon general siting
criteria, the technical aspects of ground water hydrology, and distri-
butior, system hydraulics were evaluated. This information is used to
validate the technical feasibility of available sites.
GROUND WATER HYDROLOGY ANALYSIS
Aquifer characteristics used as input coefficients to the Eastern San
Joaquin County ground water flow model ( Ref. 1) study are listed in
Table 2 and have been adopted as representative values for calculating
well drawdown curves in the study area. The aquifer is a water table
a4aifer underlain by an aquiciude and is assumed to be of uniform
thickness.
The aquifer's hydraulic conductivity is assumed to be constant and
independent of both position and direction of measurement. Weil
drawdown for wells of different depths have been computed at various
aquifer permeabilities and are presented in Table 3. The drawdown
curves for the probable range of permeabilities found in the Lodi area
are presented on Figure 7, for a well depth of 600 feet. Drawdown
depths were calculated fron Boulton's (Ref. 2) aquifer equation as
rewritte,i in the gallon -day -foot system of units by Prickett ( Ref. 3) .

WATER DISTRIBUTION REVIEW
Existing and future water lines are shown on Figure 4 and presented
in more detail in the Lodi Water plaster Plan (Ref. 4). A hydraulic
analysis on the existing 14 inch line along the Traction Company
rig; -,t -of -way was performed to evaluate any hydraulic limitations.
This existing branch can reasonably transport 4,000 gpm into the
distrbution system. Two new wells can be developed to feed into
this line with no hydraulic limitations to well placement.

Results of the drawdown
calculations, listed in Table 3, indicate that
'.
new city wells placed
at 500 foot centers
600 feet deep, would have a
f
drawdown between the two wells of 5.6 feet
(2.8 ft + 2.8 ft). Drawdown
at the well centers
would be 16.5 feet
(2.1 ft + 14.4 ft). These
drawdown depths are
acceptable values.
However, with a factor of
safety included, the
spacing of wells at
500 feet is considered a
minimurn separation,
and an 800 to 1000
foot spacing is desirable
wherever possible.

RECOMMENDED SITES
The recommended locations of four new well sites are shown on
Figure 6. Detailed sketches of each well site are illustrated on
Figures 8 through 11. Each well site overlaps two or three parcels.
The specific piece of property to be acquired should be selected based
upon the success of negotiations with each owner. All recommended
sites lie outside the central service area boundary which legally
restricts the amount of water withdrawn within the city's central
area. Property owners that may be affected by the new sites are
shown in Table 4. Following is a discussion of each reccm;nended well
site.
SITE NO. 1 - END OF LIME STREET, ADJACENT TO CENTRAL CALIFORNIA
TRACTION COMPANY (CCTC) RAILROAD TRACKS
This site is located at the eastern end of Lime Street, an unpaved
county road located 700 feet south of Winemasters Lane. As shown on
Figure 8, there are no major physical barriers to constructing a well
in the area. The CCTC railroad right-of-way extends approximately
50 feet east of the end of Lime Street. East of the CCTC railroad right-
of-way lies private property. The proposed site can lie on either one of
the two parcels shown on Figure 8. A private road running parallel to

the CCTC railroad tracks, along the eastern edge of the railroad right-
of-way, would have to be considered in the design of the site.
Site No. 1 is located adjacent to an existing 14 -inch water main, and
approximately 1,000 feet from available power. The immediate sur-
roundings of the site are agricultural lots with no existing structures.
The nearest existing well is approximately 500 feet away and is used for
irrigation purposes. The site's proximity to the %lokelumne River
provides an adequate ground water recharge potential and reduces any
problem with well drawdown.
SI-rL NO. 2 - ADJACENT TO CCTC RAILROAD TRACKS, APPROXIMATELY
1,000 FEET NORTH OF THE SOUTHERN PACIFIC RAILROAD TRACK -3
This site is located at the northwest corner of San Joaquin Warehouse,
formerly Roma Winery Co., adjacent to the CCTC railroad as shown on
Figure 9. The site can be located either on San Joaquin Warehouse
property or the property immediately north, depending upon access to
the site and cost of the site acquisition. Access will have to be attained
either by construction of a road along the west side of the CCTC railroad
in the right-of-way, access through the warehouse property, or access
through the agricultural lot north of the warehouse property.
The major
advantage of
this
location consists
of proximity to available
water and
power. The
site
is adjacent to an
existing 14 -inch water
main, and
approximately
600
feet from available
power.
SITE NO. 3 - END OF SARGENT LANE, ADJACENT TO CCTC RAILROAD
TRACKS
This site is located at the western end of Sargent Lane, which dead
ends at the CCTC railroad '.racks. As shown on Figure 10, there are no

major physical obstructions in the area other than a telephone shed 1
owned by the railroad company. South of Sargent Lane is a 50 -foot 1
strip of vacant right-of-way owned by CCTC which runs parallel to the i
CCTC railroad tracks. East of this strip, a 15 -foot private, unpaved
road has been constructed. North of Sargent Lane, a vineyard exists
adjacent to the CCTC railroad tracks.
The advantages of this area are proximity to existing power, proximity
to r proposed future water line, no existing structures in the immediate
are,i, and there is easy access to the site. Site No. 3 is located adjacent
to existing power which runs along Sargent Lane. The site is 1,300 feet
from an existing 10 -inch water line, but adjacent to a future water main
running parallel to the CCTC railroad tracks. This future water main is
described in the 1977 City of Lodi Water Master Plan. The vacant land
adjacei)t to the CCTC tracks, south of Sargent Lane is an optimal location
for this site, if acquisition costs are not a problem.
SITE NO. 4 - ADJACENT TO THE CCTC RAILROAD TRACKS, 1,300 FEET
NORTH OF KETTLEMEN LANE
This site is located at the northwest corner of the Blue Anchor, Inc.
The site can be located either on Blue Anchor, Inc., property or the
property immediately north of Blue Anchor, Inc., depending upon access
to the site and cost of the well site. Access will have to be attained
either through the Blue Anchor, Inc., property or through the parcel
immediately north of Blue Anchor. Unlike site No. 2, there is no room
for construction of an access road along the west side of the CCTC right
of way, as an established vineyard is planted up to CCTC right-of-way.
The advantages of this area
are proximity
to existing power,
proximity
to a future water line, and
there are no
existing
structures
in the
immediate area. Site No. 4
is approximately 1,200
feet from
a 21 kV
power- line runn:.rg along Curry Road and
500 feet
from power
running
into the Blue Anchor, Inc.,
property. The
site is
adjacent to
a proposed
R38cc23 -23-
/
future water
main running parallel to the CCTC railroad
tracks. This
future water main is described in the 1977 City of Lodi Water Master Plan.
There
are no
physical obstructions in the immediate area,
although there
is an existing
well west of the CCTC railroad tracks. This
existing well
i-; located on
an agricultural lot and is approximately 370
feet from the
northern property line of Blue Anchor, Inc. Access to
the proposed
site should be
be obtained through the back storage yard
of Blue Anchor,
Inc.
Blue Anchor has a holding pond onsite for washdown water and storm
drainage. This should not be a hazard to a properly constructed well.
S-QUENCE OF DEVELOPMENT
To best reinforce the existing water system grid and maintain adequate
system pressure for future development as described in the 1977 Water
Master Plan, the recommended sequence of constructing the four proposed
well sites is: Site 1 , Site 3, Site 2, then Site 4. The sequence of
construction has the effect of immediately adding capacity to both the
north and middle sections of the existing distribution system and
i provides an orderly system of water use development.

RECOMMENDATIONS FOR IMPLEMENTATION
Following is a discussion of the steps necessary to complete the goal of
acquiring the recommended well sites. Because the nature and intensity
of the opposition to new wells by property owners is not certain, two or
three properties at each site were identified as possible locations to allow
more flexibility in negotiations. Once the City Council has adopted this
report, the following steps are recommended:
R38cc25
1. Have the properties being considered appraised.
2. Begin negotiations with property owners to determine if the
properties can be obtained through negotiation rather than
condemnation.
3. If negotiations are successful, a condition of sale would be
positive results for a test well on the site. Obtain right -of -
access to drill a test well.
4. If negotiations are unsuccessful, select a specific parcel and
begin condemnation proceedings. As a first step, obtain
right -of -entry to drill a test well.
5. If test weils are satisfactory, complete negotiations or condem-
nation proceedings for the sites.

,f
6.
If test wells are not satisfactory, review the data in this
report and select a new site and begin the process again.
7.
Prepare a negative declaration and file a parcel map with the
county.
8.
-Design and construct the new well facilities.
Although
an EIR is not required, the city will have to have a parcel map
prepared
and filed for each proposed site. A negative declaration can
be used
on each individual site and the cit, should act as the lead
agency.
Because the city is exempt from county minimum acreage
requirements in this case, a County Use Permit will not have to be
obtained.
