' NVIRONMENTAL IMPACT REPORT
1.0 SUMMARY
1.1 INTRODUCTION
The City of Lodi (City), which owns and operates the electrical system
serving the City, is proposing to construct a new electrical substation and
related 60kV lines. The project, if.approved and implemented, would
consist of a new 60kV substation, the "Industrial Substation," to be
located on approximately ten acres within a present industrial area
immediately east of Lodi. A new 60KV line, approximately 1.6 miles in
length, would tap the existing Pacific Gas and Electric(PG&E) Lockeford-
Lodi No. 2 line and extend to the new substation. Modifications to
existing PG&E 60kV linesand City 12kV and 60kV line-, would provideties
from the facility to existing substations owned by (PG&E) and the City.
Underground 12kV feeders would tie the facility to the existing City
distribution network. The project would be financed entirely by the City
of Lodi.
This document was prepared pursuant to the California Environmental
Quality Act (CEQA) CA PRC Sec. 21000. No initial study was conducted
preceding this document. The project EIR Notice of Preparation was filed
by the City with the California State Office of Planning and Research on
January 25,1389.
1.2 PURPOSE AND NEED
The City receives powerfrom PG&E's Lodi Substation, located adjacentto
the City's Killelea Substation, over a single 60kV circuit. From the Killelea
Substation, power is distributed at 60kV to McLane and Henning
Substations, located along the 60kV loop around the City. Each of the
125l.(4!89) FR. ss
City's three substations serve nearby customers over 12kV distribution
feeders.
The need for the project is based on the following:
m With the high summer peak load of 1988, current on the 60kV bus
at Killelea reached 90% of the 60kV bus capacity. This 60kV bus is
supplied by PG&E over a single 60kV circuit, and is the sole source
of power to the City. Additional 60kV bus capacity is needed to
relieve the loading on the existing bus.
In addition, maintenance activities on the 60kV bus can only be
performed with the bus de -energized. De-energization of the
60kV bus would result in a complete outage to the City, or
necessitate construction of a temporary 60kV bypass circuit, a
difficult task due to the lack of space at the Killelea Substation.
This situation has resulted in very infrequent maintenance on the
60kV bus.
• The 12kV distribution feeders at Killelea emanate from 60/12kV
transformers and metalclad switchgear lineup. A fire or electrical
probiem in the switchgear would cause a complete and lengthy
outage of the Killelea 12kV Substation while repairs were
completed. Additionally, an outage to the 60kV bus to expedite
repairs would be likely. As a result of the electrical load growth
experienced within the City's electrical system, it is no longer
possible to pick up all of the Killelea 12kV load from Henning and
McLane Substations during an outage of the Killelea 12kV.
Additional 12kV capacity is required on the east side of Lodi to
accomplish this. Therefore, additional 60kV and 12kV substation
facilities, and 60kV transmission lines are required on the east side
of Lodi to correct these problems.
125L. (4/89) FR: ss 2
Construction of the proposed Industrial Substation project would allow
the City to reinforce deficient portions of their electrical system, and
provide a firm, reliable electrical supply to its customers. Specifically the
project as conceived would:
• increase reliability of service to the entire City by providing three
60kV circuits for delivery of power to the City from PG&E, rather
thanjustore as inthe present situation.
• Provide a higher capacity, dual 60kV substation bus arrangement,
so that maintenance activities can be performed without
interrupting powertothe entire City, or any portionthereof.
• Provide additional 12kV capacity on the east side of Lodi, so that
all electrical load can be served during an outage of the Killelea
Substation during the peak loadseason.
Construction of tht proposed projectwould fulfill the stated need.
1.3 ALTERNATIVES
The selection and discussion of alternatives considers informed decision
making on the part of the Lead Agency, other affected agencies and
jurisdictions, and the public. Therefore, this EIR did not consider an
alternative whose effect cannot be reasonably ascertained and whose
implementa;:on is remote and speculative.
The assessment of the proposed action considers the following
alternatives:
A. No Project
B. Alternative Technologies
C. Energy Conservation
D. Substation Site Alternatives
E. Transmission Line Route Alternatives
1 25I:(41'89) FR:ss 3
1.3.1 No Project
By maintaining ?hestatus quo, the City would continue with its
existing single circuit energy source, high risk of outages, and
difficult maintenance conditions. Therefore, the City would have
no capability to increase power supply capacity or improve
reliability.
The No Project alternative is not considered a viable alternative
action for meeting the stated need.
1.3.2 Alternative Technoloqies
Available technologies for meeting increased demand would
include the installation of City -owned thermal generation within,
or immediately adjacent to the City. The high capital investment
and potentially adverse environmental effects, as well as the
inherent increase in cost to rate payers, combine to preclude this
option from consideration.
An additional alternate technology to be considered for the 60kV
transmission line is that of underground construction. Although
there has been underground construction of transmission systems
in the United States since the late 1920s for lower voltage
distribution lines and some high voltage (HV) systems, most HV
systems (greater than or equal to 60kV) have been constructed in
areas where overhead lines were not an option such as short
sections in central -city locations. It is important to note that
technological requirements for underground HV transmission lines
are markedly dissimilar from those for lower voltage distribution
lines. Undergrounding of HV transmission lines is vastly more
complex and costly, primarily because of problems associated with
dissipating cable heat. Design parameters and other restrictions
combine to limit the use and application of underground
transmission systems.
?25L (4/39) FR. ss 4
The basic cost of undergrounding a 60kV line would be at least
four to ten times the cost of building an overhead line. While
underground lines are relatively unaffected by weather
conditions, they remain vulnerable to leaks, dig -ins, washouts,
seismic events, and cooling -system failures. As this line would
represent a primary source to the City, outages of long duration
would be unacceptable.
The principal environmental benefit of undergrounding a
transmission system isthe reduction cf adversevisual and aesthetic
impacts (although ancillary facilities on, or adjacentto the right of
way would be visible).. However, the proposed line would be
constructed in an industrial area Vrhere overhead utilities are
commonplace, and frequently support multiple uses such as local
electric distribution lines and communications cables on the same
pole. On balance, the environmental benefits of undergrounding
do not appearto outweigh the adverse impacts.
There are no alternative technologies or substitutions for
substation construction.
1.3.3 Energy Conservation
The City Electric Utility Departrrr:-nt has instituted a variety of
energy conservation programs. Load Management studies are
being conducted that provide customers with computer models of
their energy use pattern. These data are used to aid the customer
in determining options for more efficient energy use and a
subsequent decrease in their demand charges. The reduction in
customer demand due to load management ultimately reducesthe
City's demand and cost of power purchases. Through load control,
the City has a goal to achieve a 6 megawatt reduction by 1992.
Conservation and load management recommendations are
provided to customers through an energy audit program.
1, 25L:(4/89,1 FR -ss 5
The Electric Utility Department has conducted energy audits of city
facilities and has initiated the installation of high efficiency
lighting in public facilities and in the City's street lights.
In order to detect and correct inefficient equipment, the Electric
Department has conducted infra -red scanning of their lines and
substations.
The "Pull the Plug" public awareness load management program
is in effectduring the air conditioning season to bring down the 1-
7 p.m. load during the hottest days of the months.
These conservation measures reflect responsible Electric
Department management. However, the City's purpose as stated
is notto reduce energy consumption through the proposed action,
but to provide reliability for the base load. Because energy
conservation can affect energy demand, but not provide the
means of providing reliability and appropriate distribution of
electric power, conservation cannot be considered as an
alternative action for meeting the project purposes.
1.3.4 Substation Site Alternatives
The criteria for suitable substation sites include developed or
planned street access; ease of access to existing PG&E and City
60kV circuits and City distribution circuits; suitable parcel size
(preferably 10 acres); and central to industriai loads. Several sites
meeting these criteria are found within an area bounded by Pine
Street on the north, IndustrialWay on the south, Central California
Traction Railroad (CCTCo) on the east, and Highway 99 on the
west. Portions of this area are outside the City limits. The area
within the City limits is zoned Heavy Industrial (M-2). Those
portions of the study area that are outside the City limits are
zoned Interim Protected Agriculture (I -PA) or Limited
Manufacturing (M-1). The proposed facilities are permitted uses
within the I -PA zoning designation as described in the September
5L:(4,189) FR: SS b
9, 1988, revision of the San Joaquin County Ordinance Code
Section 9-3200.8 Civic Use Types, Part (k).
Pipelines and Utilities Major. Large scale facilities used
in the transmission of electricity, liquids, or gas. Typical
uses include electric or natural gas transmission lines
and substations, and petroleum pipelines;
Two alternative substations sites were considered: SS -1, located at
the southeast corner of Cluff Avenue and Lodi Avenue.: and SS -2,
located on the south side of the CCTCo from the future
intersection formed by the extensions of Lodi Avenue and Guild
Avenue.
Both sites are currently vineyards. The entire tract is immediately
adjacent to PG&E's Lockeford-Lodi #3 60kV circuit, and also
intersects the proposed new 60kV line. Being farther east of city
facilities than SS -1, development of SS -2 would require additional
line lengths to connect the substation with existing City lines. SS -2
is not directly served by a City street.
An alternative substation action considered, but rejected, was to
expand the existing Killelea Substation. This alternative wouId not
increase the number of delivery circuits, and would therefore only
partially satisfy the stated need. Because ofthe lark of vacant land
adjacent to this facility, any expansion would impose severe
impacts upon the surrounding neighborhood. For these reasons,
this alternative was not considered for further study.
125L'.(4/89) FR:ss 7
1.3.5 Transmission Line Route Alternatives
Transmission line routing alternatives -were considered based upon
their ability to satisfythe project purpose and need, and the City's
routing criteria as follows:
® Avoid excessive impacts upon agricultural lands.
U Utilize existing access.
U Minimize routing through areas of congested development.
® Avoid areas representing engineering hazards or requiring
costly design measures.
® Minimize the line length.
U Avoid areas of critical environmental concern.
Construction of project facilities is scheduled to begin in January
1990 with completion by May 1990. Facilities planners generally
assign a project life of 35-50 years for high voltage facilities.
Preliminary screening of potential alternative routes was
conducted to determine areas of substantial conflict based upon
environmental concerns, obvious potential public and agency
opposition, and inability to conform substantially with the primary
routing criteria. Two routing alternatives were identified from the
preliminary screening process. The routes, shown on the project
map (Appendix 6) are: Route 1 and Route 2.
Route 1 consists of links 1. 1, 1.2, 1.3, 1.4, 1.5, 1.6. This route would
tap the PG&E Lockeford-Lodi Nc. 2 line near the northeast corner
of the Guild Winery. From the tap point the route extends along
the west side of the CCTCo for approximately 2,720 feet to a field
edge road. A portion of this section would be underbuilt with
125L (4/89) FR:55 8
existing distribution that serves a City pump. A young cherry
orchard is located on the west side of this section near :;le north
end. Vineyards are found along the west side of the CCTCo
adjacent to the southern end. Turning west, the route extends
along the field road to Guild Avenue. A portion of this section
would be undorbuiltwith distribution to serve a private pump east
of Guild Avenue.
A route following Guild Avenue from the northwest comer of the
Guild Winery to Highway 12 was also examined. However,
beginning approximately 700 feet north of Highway 12 and
extending north approximately 1300 feet, significant portions of
Guild Avenue are bordered by King Palm, Eucalyptus, and Oak
trees. Placing a 60kV line along the street would require severe
pruning and possible removal of trees. As that impact was
considered unacceptable, this alternative was rejected from
further consideration.
An additional alternate to this section would have continued
south along the CCTCo across Highway 12. However, sufficient
conductor to building clearance is restricted by two buildings
making this alternative undesirable.
Turning south on Guild Avenue, the route traverses to the future
extension of Lodi Avenue, crosses to the south side of the CCTCo,
turns west and extends to either SS -1 or SS -2. This route section
passes Dart Container Corp. and active vineyards on either side of
the future extension of Guild Avenue. From Pine Street south to
the future extension of Lodi Avenue, the Lodi Cemetery is on the
east and vacant land on the west. However, the land on the west
has been platted for small, zero setback industrial lots to be
developed as Griffin industrial Park. Vineyards are again
encountered between the south side of Lodi Avenue and the north
side of CCTCo.
125LAI 89) FR:ss 9
Route 2, consists of !inks 2.1 , 2.2, 2.3 2.4, 1.5, 1.6. This alternative
would tap the PG&E Lcckeford-Lodi No. 2 601kV line at a point near
the Mokelumne River, approximately 1,200 feet northeast of the
end of Kennison Lane. From the tap point, the route traverses row
crops across the river's floodplain for approximately 1,120 feet.
Fromthe floodplain rim, the route continues south along a private
farm road to Highway 12. This section traverses lands in vineyard
on the west and currently vacant lands on the east. From Highway
12, the route continues south along property lines through
vineyards to the east end of Pine Street. Turning west on Pine
Street, the route follows an existing distribution pole line to the
northwest corner of the Lodi Cemetery. From that point, routes 1
and 2 would have the same alignment.
In addition to the above described new 601kV transmission line,
three short sections of 60k`J line would be constructed to link the
proposed substation with the City's existing 601kV loop. These line
segments of approximately 1400, 1700, and 6900 feet respectively
(7400 feet of which would be overbuild of existing 12kV lines),
would each be routed within the existing industriai area of the
Lodi city limits. Each new segment would be routed to take
advantage of i;-iki-g sections of existing 121kV lines.
An alternative route considered but rejected would have traversed
Kennison Lane from a tap point near the river to Highway 12.
Because of the perceived negative visual impact of the line upon
the Kennison Lane neighborhood, coupled with the requirement
to trim and possibiy remove trees, this alternative was not
considered for further study.
1.4 SIGNIFICANT EFFECTS AND PROPOSED MITIGATION
Environmental consequences of the proposed action and alternatives
would be those residual imparts remaining subsequent to the process
that has identified, evaluated, and integrated initial impacts with
appropriate mitigation measures. That process involved assessing
125L (4189) FR ss 13
impacts by comparing the proposed action with the pre -action
environment, and determining mitigation that would avoid, reduce, or
eliminate longterm impacts.
Potential significant impacts were identified during routing studies and
with discussions with City and County personnel. Additional comments
on impact or issue identification were solicited from state and federal
agencies through the filing of the project Notice of Preparation.
Potentially significant impacts identified through this process were:
effects upon agricultural activities; effects on existing orchards, shade,
and ornamental trees; effects on existing residential areas; and overall
visual impact of project facilities.
Perhaps the most significant potential impacts of those listed would be
effects on agricultural patterns and practices, the line's presence in farm
and residential areas relative to the visual effects, and the potential for
tree removal to accommodatethe right of way. In addressing the impact
upon area agriculture, it is noted that the San Joaquin County General
Plan discourages the unnecessary conversion of prime farm land to
incompatible uses. The range of alternatives for the line route vary in
their right of way requirement from 17.95 acres {o 19.84 acres for the
substation and new line segments. Each alternative route would traverse
prime farm land; therefore, appropriate mitigation would address
measures to minimize effects upon those lands. Such measures would
include:
o Select as short a route as is practicabie.
Place faciiitios on field edges, adjacent to roads, and along existing
pole line right of Nays so their effect on agricultural operations
and residential developments would be minimized.
The implementation of these procedures would, in large measure, offset
project impacts to farm and rural residential areas.
1251:(4'89` :R. ss 11
Project related impacts to earth resources would be those which may
accelerate the rate of soil erosion, or cause soil compaction. Disturbance
of ground cover and soil compaction would occur as a result of
construction activities on the right of way. However, these effects are
not considered to have significant long term consequence. Fugitive dust
caused by construction activities would be easily controlled by requiring
contractors to implement common dust curtailment measures such as
watering construction travel ways and other areas of surface
disturbance. individual right of way agreements would stipulate
appropriate revegetation according to the grantor's specifications.
Concern for biological resources would include project affects upon
threatened or endangered plant and animal species, critical. habitats,
unique vegetative types, of areas of low vegetative potential.
Consultation with the California Natural Diversity Database has been
initiated. Should threatened and endangered species be found within
the immediate project area, measures would be taken to avoid
disturbing or impacting these populations. Detailed examination of
these areas maybe found in Section4.
To satisfy compliance with Section 106 of the National Historic
Preservation Act, as implemented through 36 CFR 800, the California
Office of Historic Preservation and the Central California Information
Center have been consulted for comments relative to historical or
cultural resources. Their response is noted in Section 4 and Appendix 4.
The proposed Project would effect short-term increases in noise levels
from the use of various vehicles and machinery during construction and
maintenance. During periods of rain and fog some very low-level hissing
may be noticed in the immediate line vicinity. For most persons,
however, such noise is below the minimum threshold of hearing. Noise
generated by the substation equipment would also be confined to a level
of approximately 61 Ldn. The San Joaquin Council of Governments allows
a noise level of 75Ldn at the property line in industrial developments.
' 15L. 89) "r R. ss 12
No adverse effects are anticipated to be perceived as a result of Project
facilities. Thissubject area is addressed in more detail in Section 4 of this
document.
1.5 AREAS OF CONTROVERSY
Some level of controversy is anticipated to arise over the project's visual
impacts and effects upon agricuitural practices.
1.6 ISSUES TO BE RESOLVED
Of primary concern will be the certification,of the environmentally and
technicaily preferred transmission line route and substation site.
Mitigation of areas of controversy may be stipulated by the project
proponent (the City) and are discussed in detail in Section 4.
1.7 ENVIRONMENTALLY PREFERRED ROUTE
Based upon the review of potential impacts, route and site evaluation
worksheets, individual routing and siting preferences, and agency
comments; the cumulative land use, engineering and environmental
consequences of each route and site were summarized (see Tables 1&2 in
Appendix 2 and Section 5). The preferred route of least environmental
impact was identified based upon a review of these data in relation to
evaivation criteria. While the two alternative substation sites have been
evaluated and summarized, a preferred location has not been identified
in this Draft EIR (DEIR).
Publicand agency comment on the Draft EIR will be solicited subsequent
to its being approved for release by the Lodi City Council, filed with the
Office of Planning and Research, and announced in the local newspaper.
The final project disposition will result from an analysis of all data
presented. Based upon the DEIR analysis process, the project proponent
prefers the 60kV line alternative Route 1. Substation site evaluation
results indicate both alternatives to have relatively equal merit. The
ultimate substation site selection would therefore be based on the
i?SL:(4;89'.FF ss 13
preference of the project proponent.
A summary of the land use, engineering, and environmental evaluation
criteria associated with the preferred and alternate routes and the
alternate sites is presented in Appendix 1 and Section 5. The locatior,s of
alternate sites and routes are shown in Appendix 6. Correspondence
solicited through the State Clearinghouse is contained in Appendix 4.
2.0 PROJECT5ESCRIPTION
2.1 HISTORY
The City of Lodi'(City) operates transmission and distribution systems
solely within the Lodi city limits for the purpose of providing electric
service to City customers.
Under its present operating configuration, the City purchases power
from Western Area Power Administration (WESTERN) and NCPA. These
resources are delivered from PG&E's Lockeford Substation over four
PG&E circuits of delivery to PG&E's Lodi Substation and thence over a
single circuit to the City's adjacent Killelea Substation. Because of the
overall growth of the City, substation facilities are reaching the point
where, in the event of an outage at one substation, the others cannot
adequately assume the additional load. During the summer of 1988, the
Killelea Substation 60kV bus reached 90 percent of its capacity. Any one
of several contingencies occurring under such a ioading condition would
cause an outage of potentially several hours affecting all of Lodi.
2.2 DESCRIPTION OF TH E PROPOSED ACTION
2.2.1 Action and Benefits
Implementation of the "industrial Substation Project" would
consist of: constructing approximately 1.6 miles of 60kV
transmission line to provide a new source of delivery from PG&E to
12 5L: (4.189) FR ss 14
the City; construction of a new 60kV substation to be the new
point of delivery; and modifications to existing PG&E 60kV lines
and City 12kV and 60kV lines to tie together new and existing
facilities.
Construction of the proposed Industria! Substation project would
allow the City `o reinforce deficient portions of their electrical
system, and provide a firm, reliable electrical supply to its
customers. Specificallythe project as conceived would:
• Increase reliability of service to the entire City by providing
three 60kV circuits for delivery of power to the City from
PG&E, ratherthan Justone as in the present situation.
• Provide a higher capacity, aual 60kV substation bus
arrangement, so that mainc;:nance activities can be
performed without interrupting powerto the entire City.
• Provide additional 12kV capacity on the east side of Lodi, so
that all electrical load can be served should an outage of the
Killelea Substation occurduring the peak load season.
The new 60kV transmission line would extend from a tap point on
PG&E's Lockeford-Lodi No. 2 line to the new substation. The
preferred route, approximately 1.6 miles in length, would traverse
existing and planned transportation routes. The proposed design
would consist of a single circuit wood pole line with horizontal
post insulators (see Fig. 1). In several locations the route would
follow that of existing distribution lines. in these cases the existing
lines would be moved onto the new poles and the old poles
removed (see Project Area Map - Appendix 6). The design criteria
would conform to California General Order 95.
The new 60kV line would require a forty foot right of way. The
total amount of land required for the preferred route right of way
would be approximately 7.95 acres.
l25L (4/89) FR: ss 15
Under a City/PG&E agreement, PG&E would design and build this
line. In addition, PG&E would acquire the necessary rights of way.
Negotiations with landowners for easement rights would be
conducted according to the California Uniform Relocation and
Property Acquisition Act. Landownerswould be compensated for
the easement on a basis of fair market land value. If negotiations
are not successful, condemnation proceedings would be
undertaken. While many uses are allowed within transmission line
easements, certain restrictions are imposed. These would
primarily concern the erection of structures within the easement,
or the conduct of activities that might pose a safety hazard or
impede the operation and maintenance of the line.
2.2.2 Tech n ica I Characteristics
Conceptually, the proposed action would consist of two major
elements:
• A single circuit 60kV wood pole transmission line
A 60kV-12kV substation
in addition, modificationsto existing City 60kV and 12kV lines
would be made, and short segments of 60kV lines constructed
within the City to interconnect existing facilities.
Siting analysis has identified suitable alternative substation sites
and transmission line routes. in order to plan for future
contingencies, the City would purchase a ten acre parcel for a
substation site. The project as proposed would require a fenced
area of approximately three acres (Fig. 2). Alternative sites are
located at the southeast comer of the Lodi Avenue and Cluff
Avenue intersection and on the south side of the CCTCo near the
east end of Lodi Avenue (see ProjectArea Map - Appendix 6.)
125L (4,189) FR ss 16
The Industrial Substation would be a completely new facility
requiring a new site separate from existing facilities owned by the
City. Entry and exit 60kV-transmission lines from thestation'would
tie to stations owned by Pacific Gas & Electric (PG&E) and the City.
Underground 12kV feeders would tie to the existing city
distribution network.
Tne proposed substation would consist of two 60kV yards and one
12kV yard with space to accommodate future facilities. The 60kV
yards would be double bus -double breaker schemes with
disconnect switches on the t:vo main buses to tie the City (load)
60kV yard with the PG&E (source) 60kV yard. Revenue metering
points for WESTERN would be located on the two main buses on
the source side (PG&E) of the 60kV bustie switches.
The existing PG&E Lockeford-Lodi Line No. 3 would be cut and
looped through the Industrial Substation. A new 60kV line
segment would be built from the existing PG&E Lockeford-Lodi
No. 2 line to the industrial Substation.
Three 60kV lines from the City yard would tie to the existing City
60kV system. Two terminals on the City 60kV bus would connect
to the two 60-12kV transformers that feed'the 12kV yard.
The 12kV yard would consist of a main and transfer bus scheme
with a switch -sectionalized main bus and one tie breaker. Five
underground feeders would be installed initially with buswork
and structures provided for three additional feeders. Spacewould
be provided for a future third 60-12kV transformer and five 12kV
feeder positions.
Refer to the Substation General Arrangement Diagram (Fig. 2) for
details.
Substation and associated facilities would require a site of
approximately ten acres. A three acre enclosed portion of the site
x251:(4,189) FR ss 17
would contain transmission line entry and exit structures, power
circuit breakers, two 60-12kV power transformers, rigid.buswork,
water and sewer lines extended'for a small control house with
restroom, and various pieces of ancillary operating, metering, and
safety devices. The power circuit breakers would utilize an arc
extinguishing gas compound called SF6, in circuit breaker tanks.
SF6 is a nontoxic, non -explosive, inert gas; however, because the
gas displaces oxygen, under enclosed conditions there is a risk of
suffocation. The tanks for the power transformers would each
contain 6,000 gallons of insulating mineral oil. Standard oil
containment devices, either sealed earth berms or concrete pad
and walls, would be constructed around the transformers to
contain oil in the unlikely event of a ieak or spill.
The developed area of the site would be enclosed by a ten foot
wood slat chain link fence topped with three strands of barbed
wire.
2.2.3 Project Cost
Engineering, right of way, and construction costs have been
estimated for the preferred route and substation. The cost of
other considered alternativeswould not vary significantly from the
preferred alternative. While a cost -benefit analysis has not been
developed, the No Action--therefore--No Cost alternative would
result in City power supply and reliability limitations in the near
future.
125L:(4:891 FR:ss 18
Cost estimates for ?he project as proposed areas follows:
Substation (Design/Construct) $3,820,000
60 kV Transmission Line
(PG&E Design/Construct & Right ui Way) $481,000
60/12kV Line Interconnections (Design/Construct) 8407,000
Total Estimated Cost -Preferred Action $4,708,000
These costs are preliminary, planning level estimates. Budget
estimates for construction inspection ana project management are
not included.
2.2.4 Intended Use of EIR

3.0 ROUTING AND SITING ANALYSIS APPROACH
In order to identify a preferred transmission line route and alternative sites for
the substation, interrelated factors of engineering and environmental studies
of identified alternatives have been evaluated.
3.1 GENERAL
From a strictly pragmatic sense, few constraints exist that make the
placement of a transmission line impossible. However, given a choice of
options governed by economic and environmental variables, the
selection of a route or site may be made which represents a responsible
assessmentof these options. The environmental impactsof the proposed
action are considered in a broad sense to include an assessment of both
beneficial and adverse affects on the social, economic, and natural
environments. While many impactscannot be predicted with certainty,
their probability of occurrence is made easier to predict through a
systematic assessment process.
For the City of Lodi Industrial Substation Project, alternatives have been
seiected for evaluation that represent relative degrees of vaiidity.
While any number of environmental elements may be considered, notall
would be relevant to the identification and evaluation of each
alternative. Those eiements that were considered relevant are discussed
in Section 4. They are grouped into four general categories:
• Living Components
• Non-LivingComporents
• Human Values
• Demographicsand Socioeconomics
The probable effects of the proposed action on each of the elements
were weighed against the pre -action condition in selecting and
evaluating alternate sites and routes. Only those primary routes that
represent unique opportunities were retained for an in-depth analysis.
125L:S4189, FR: SS 2'�
The two primary routes initially studied both represent north -south
corridors. Because of the,City's need to tie the new 60kV iine into the
Killelea, lienning, and McLane Substations, several north -south route
segments were examined. Field review of these links resulted in the
determination that not all links offered unique solutions that are not
made available via another link. Therefore given the desirability of
examining truly unique link combinations, some links were excluded
from further study. Those excluded links were: the CCTCo beginning
approximately 500 feet north of Highway 12 to Sargent Road; Guild
Ave:iue from the Guild Winery to a point approximately 500 feet north
of Highway 12; and Kennison Lane. These links were analyzed but not
considered further as they quantitatively present a larger number of
potential conflicts, i.e. commercial buildings, homes, barns, tree
trimming or removal, and additional angles.
A route analysis and weighting scheme was developed to optimize an
objective analysis of link segments, see Appendix 1 - Route
EvaluatioNWeighting Analysis Criteria Definitions, and Appendix 2 -
Route and Site Evaluation Worksheets. The preferred alternative is
defined as the set of route segments that offers the best balance
between environmental, engineering, land use concerns, and probable
project impactswhile satisfying the stated need for the project.
The preferred alternative selection process proceeded as follows:
1. Identify a study area that is large enough to provide
alternatives for study within the parameters of prudent
economic, engineering, and environmental constraints.
Confine the study area to allow the entire area to be studied
at a satisfactory level of detail.
2. Prepare a study area environmental data base and constraint
analysis.
25L t4,-69: Fn Si 23
3. Assuming a requirement for a forty foot right of way and a
ten acre substation site, select apparent "least impact" routes
and sites.
4. From the identified alternatives, select a "preferred
alternative route."
S. Assess potential impacts of each alternative.
6. Develop proposed mitig-:ion.
7. Assemble a Draft EIR
The study area for this proposed action is believed to contain all feasible
alternatives for the placement of a 60kV transmission line and a 60kV - 3
12kV substation while fulfilling San Joaquin County's and the City's
routing/siting criteria:
• Avoid excessive impacts upon agricultural lands.
• Utilize existing access.
• Minimize routing through areas of general residential and
commercial development.
• Avoid areas representing engineering hazards or requiring
costly design meast►res.
o Minimize the line length.
o Avoid areasof critical environmental concern.
Alternate routes within the study area were identified based on field
inspection and on the information presented in this report. These routes
are presented with the understanding that their position on the study
area . yap does not represent an exact renterline iocatiori. Detailed
125Lj4r89) FR:ss 25
engineering, surveying and design may result in minor deviations from
the routes as mapped in this report. Individual structure locations would
be determined through. a process of design requirements and public
comment.
3.2 ROUTE EVALUATION CRITERIA
Route and site evaluation criteria that representthe engineering, land
use, and environmental concerns presentwithin the study area are listed
in Tables 1 and 2. Each criterion is assigned a relative value of
importance or weighting. These weights range in value from 5, which
represents a high potential for conflict and/or cost, to -3, which
represents a positive impact, and/or less cost. When the weighting is
multiplied by the number of occurrences along a given route segment or
link, the resulting score reflects the compatibility of the link with the
specific criterion. When the links are combined and totaled, the route
and/or site with the fewest occurrences, or lowest numerical score is
considered the best. Appendix 1 contains a detailed discussion CE all
route evaluation and site evaluation criteria, and their respective weight
assignments.
3.2.1 Link/Site Development
Each route is composed of route segments or links. Two primary
routes and two substation sites have Seen identified. The links,
routes, and substation sites are shown on the project area map
included in Appendix 6
3.2.2 Link/Site inventory and Scoring
Each link and substation site was reviewed using the route and site
evaluation criteria worksheets. The inventory process involved
counting the number of occurrences (i.e. number of angles greater
than 600, each thousand feet requiring new access) for each route,
or site evaluation criteria. Since the routing of the 60kV line for
this project is ?or a relatively short distance, approximately 1.6
125L:(4189) FR ss 26
miles, a unit of per thousand feet was used for each link rather
than miles or feet.
These tabulated occurrences of environmental, land use, and
engineering conditions along each link or within each site were
then multiplied by their respective weights, and a total score was
calculated. Forexample, in the engineering category, the criterion
"number of angles greater than 600" hasa weight of four. If link
has two angles greater than 60°, then it would have a score of 8
(two angles times a weight of four). The weighted scores were
then added together respectively to obtain a total score for each
link and site. The lower the number, the more acceptable the link.
Appendix 2 shows the result of the inventory and total scoring for
all links and sites.
3.2.3 ROUTE AND SITE SCORING
Route scores were determined by adding the individual scores of
links that make up each route. For example, the total score for
Route 1 wasobtained by adding the totalsof links 1.1, 1.2, 1.3, 1.4,
1.5, and 1.6. The route totals were also broken down into totals of
the three major criteria categories: land use, engineering and
environmental. The land use score for Route 1, for example, was
obtained by adding the land use scores for ail link segments that
made up Route 1 . Table 3 of Appendix 2 is the form developed to
summate these totals and also to assign the route ranks discussed
below.
Substation site scores were also obtained by adding up the totals
of the three major criteria categories. However, in this instance,
the scores of this project element were not incorporated to arrive
at a total project score.

4.0 ENVIRONMENTAL CONCERNS AND IMPACTS
For the purposes of this report, environmental impact has been defined as a
modification, or anticipated modification, to the environment as it presently
exists resulting from the proposed action. Environmental impacts could result:
If environmental change or stress occurs to biotic populations or natural
resources affecting their safety, health, abundance, productivity or
aesthetic orcultural values.
e If the change or stress affects the diversity and variety of individual
choice, the standard of living, or the extent of sharing life's amenities.
• ff the change or stress affects ?he quality of renewable resources or the
recyclingof depletable resources.
Significant effect on the environment means a substantial, or potentiaiiy
substantial, adverse change in any of the physical conditions within the area
affected by the project including land, air, water, minerals, flora, fauna,
ambient noise, and objects of historic or aesthetic significance. An economic or
social change by itself would not be considered a significant effect on the
environment. A social or economic change related to a physical change may be
considered in determining whether the physical change is potentially
significant.
Environmental impacts can be positive (beneficial) or negative (adverse) as a
primary result of the action (direct) or as a secondary result (indirect). These
impacts can be permanent or long-lasting (long-term), or temporary or short
duration (short-term). They can vary in degree or magnitude from no change,
or only slightly discernable change (no identifiable impact), to a total change
in the environmental condition or system (high impact). The level of impact is
described as follows:
High impact - A high level of impact would result if the construction,
operation, maintenance or abandonment of the proposed Project would
potentially cause a significant or substantial adverse change or stress to
1251 (:.'89) FR:s 30
an environmental resource or resources.
Moderate impact - A moderate impact would result if the construction,
operation, maintenance or abandonment of the proposed Project would
potentia:'v cause some adverse change or stress (ranging between
significant and insignificant) to an environmental resourceor resources.
Low Impact - A low impact would result if the construction, operation,
maintenance, or abandonment of the proposed Project would
potentially cause an insignificant or small adverse change or stress to an
environmental resource or resources.
No identifiable impact - No identifiable impact would be indicated
where no measurable impact would occur to the specific resource(s)
under investigation.
Duration of impacts has been defined for the potential and residual
impactsdescribed as follows:
Short-term impacts are those changes or stresses made upon the
environment during construction. Such change would generally revert to
preconstruction conditions a?, or within a few years of, the conclusion of
the construction phase. Although short in duration, such impacts are
normally obvious and often highly disruptive in nature.
tong -term impacts are those changes or stresses made to the
environment during construction and operation that would substantially
remain for the life of the proposed project (35-40 years) and beyond.
4.1 ENVIRONMENTALSETTING
The City of Lodi is located in the north -central portion of San Joaquin
County, which is the northernmost county in the San Joaquin Valley, and
is a part of the Central Valley. The most recent population estimate
(March 1, 1989) for Lodi is 50,000. In Lodi the land slopes at a rate of
approximately five feet per mile from the northeast to the southwest.
1 ZSL: (4/89) FR: 55 31
The climate in the project area is characterized by hot, dry summers, and
mild, wet winters. Temperatures may dip below freezing in winter with
an average January minimum of A8°F. In summer, temperatures often
exceed 100°F; the average July temperature is near 90°F. The mean
annual rainfall is about seventeen inches and generally occurs during
storms between October and April. Dense fog can occur in late autumn
and early winter but as the daytime temperatures rises, it usually
disperses unless a stagnant atmospheric condition exists during which
time the fog may last for weeks.
4.2 FLORA AND FAUNA
The project would be located in a predominantly developed,
industrialized area. Any undeveloped areas are mainly agricultui-al.
Since much of the project area has been in urban or agricultural uses for
many years, little if any native California vegetation remains.
Nut and fruit orchards, graoe vineyards, row corps, grasses, ornamental
and shade tree species, and a few isolated palm trees comprise the
vegetation found in the project area. The vegetation serves as habitat
for animals, erosion control, a contributor of oxygen to the atmosphere,
and possibly a neutralizer of noxious air pollution.
The presence of mammals, birds, and reptiles occurs in direct association
with v^getative communities. The agricultural land provides a food
source for wildlife. In the study area, the Mokelumne River flow; year
round.
Impactsand Mitigating Measures: The proposed project is not expected
to pose a long-term impact to wildlife species, or to degrade wildlife
habitat. The tap point for Route 2 is locatedwithin the floodplain for the
Mokelumne River, but is not located within a riparian area. No impact to
riparian zones are expected.
Minor tree trimming along the selected transmission line route might be
necessary on a case by case basis.
125L:(4189) FRISS 32
4.2.1 Threatened and Endangered Species
Consultation with the California Natural Diversity Database
indicates there are no state or federally listed rare, threatened, or
endangered species or habitats of special concern located within
the project area. Should threatened and endangered species be
found within the immediate project area, measures would be
taken to avoid disturbing or impactingthese populations.
Impacts and Mitigating Measures: Consultation with the
appropriate agencies would be undertaken should threatened or
endangered species be found within the project area. From this
consultation appropriate mitigation for impacts to these
populations would be implemented.
4.3 SOILS
The area is dominated by moderately deep to very deep soils of nearly
level to gently sloping alluvial fans. These soils, Hanford - Greenfield
Association loam, have a Class I capability rating assigned by the U.S.
Departmentof Agriculture's Soil Conservation Service, and have virtually
no limitations for agricultural purposes, as is evidenced by the wide
variety of crops grown in the area.
For the purpose of substation and structure construction, the bearing
capacity of the soil ic adequate at approximately 2,000 pounds persquare
foot with no expa .1ve characteristics.
Impactsand Mitigating Measures: Right of way clearing, augering holes
for structures, and substation site preparation are project activities that
would have varying degrees cf impacts to the area soils.
Soil disturbing activities along the rights of way would be short term and
car. be minimized by efficient construction methods, thereby reducing
vehicular traffic. Since there is very little gradation of slope, there would
125L.114r89)FR:ss 33
be little erosional threat as a result of construction activities. The
inherent productivity of the area soils would allow rapid re-
establishment of native vegetation in the areas that are not cultivated.
4.4 FLOODPLAINS AND WEfLAND5
According to FEMA Floodplain Map No.165 for San Joaquin County,
issuedJuiy 4, 1988, Route No. 1 does not liewithin a 100 -year flood plain.
Route No. 1 is located in Zone B, which is a 500 -year floodplain area.
Route No. 2 would have its tap point located within the 100 -year
floodplain. The rest of the Route No . 2 is located in Zone B.
Impacts and Mitigating Measures: If Route 1 is certified, no impacts
would result to wetlands. Route 2 would involve minor, short terrn
impacts associated with constructing the tap point in the Mokelumne
River flood plain. The tap point for Route 2 would not be located in a
riparian area.
No wetlands would be crossed or disturbed by the Project. No unique
wetland wildlife habitat occurs in the project area.
No impacts to surface or ground water resources should result from the
project.
4.5 GEOLOGY AND SEISMICITY
During the last several million years, the Great Valley filled completely
with sediment eroded from the canyons of the Sierra Nevada and
became dry land. Underlyingthese sediments are manythousands of feet
of the monotonous Great Valley Sequence rocks, -which appear to have
begun as sediments on the floor of the ocean, just as the same kinds of
sediments are being deposited offshore today. Most of these sediments
are muddy sandstones, layered with a few iayers of black basalt lava
flows and beds of chert, a rock composed of the skeletons of microscopic
animals all welded together by recrystallization.
5.(4/89) FR: ss 34
The Great Valley of California, also known as the Central Valley, is about
450 miles long with an average width of about 50 miles. The northern
portion of the valley is called the Sacramento Valley and the southern
portion the San Joaquin Valley. The northern -most fault, the Stockton
fault, which is about 14 miles south of Lodi, is the boundary generally
used by geologists to separate the Great Valley into the two sub-bas;ns.
Lsdi is located directiy in the middleof the separation point.
According to the 1985 Uniform Build ng Code, the City of todi is located
in seismiczone 3. Potentially, the most active fault in closest proximity is
located 22 to 32 'les west of Lodi in the Rio Vista -Montezuma area. The
Stockton fault is considered inactive while the nearest historically active
fault is the Antioch fault located about 30 miles southwest. The
infamousand active San Andreas fault is about 70 milessouthwest.
Fine grained cohesionless soils and sands of low permeability, loose to
medium in density that are in a s 3turated state are most susceptible to a
phenomenon called liquefaciion. Liquefaction refers to the
instantaneous, partial to complete loss of soil strength, and can result in
a catastrophic failure of foundations.
Impacts and Mitigating Measures: The line would be designed to meet
earthquake standards. It is anticipated that explosives would not be
necessary because bedrock would not be encountered during pole
structure placement.
When a final route has been seiected, loading and structure types
finalized, and a geotechnical program completed, a found;,tion analysis
should be done to address specific liquefaction potential.
4.6 AIR QUALITY
The project area located in the northern -most portion of the San
Joaquin Valley Air Basin. The Basin air quality regularly violates the
standardstor ozone, carbon monoxide, and total suspended particulat. s.
1251:0189) FR -ss 35
From May to October, the prevailing west and northwest winds may
bring pollutants from the more heavily populated Bay Area into the Loai
area. From October to February temperature inversions may occur that
trap pollutants nearthe earth's surface.
Corona, which is the ionization of air around a charged object, occurs at
the surface of a power line becausethe electricfield strength exceedsthe
insulating capability of the surrounding air.
The corona phenomenon also generates ozone and cxides of nitrogen in
the air around lines. Ozoneforms naturallyfrom lightning dischargeand
from reactions between solar and ultraviolet radiation and air pollutants.
In the home, electronic air purifiers and some wastewater treatment
sys `ems produce ozone.
Impactsand Mitigating Measures: The proposed projectwould have no
longterm deleterious effect on air quality; however, during construction
some short term increase in dust and vehicle emissions may be
experienced. Typical mitigation would call for the construction
contractor to provide water trucks or other dust abatement measures in
areas along dirt roadswhere dust may be a problem.
The estimated maximum incremental ozone levels at ground level due to
the proposed transmission line are insignificant. Corona -produced
oxidants from the proposed line would not have an impact.
4.7 NOISE
Motorized transportation corridors represent the major noise problem
areas with decibel levels decreasing as the distance betweer, the source
and listener increases. Agricultural machinery and aircraft operations
also contribute to background noise. Areas exposed to less than
day/night average noise levels (Ldp)) of 75 decibels are considered
acceptable for industrial development.
125L (4189) Fa ss 36
A
The transformer noise level generated by the proposed substation would
approrimately 61 Ldn at the nearest property line.
Impacts and Mitigating Measures: The greatest noise impact from the
proposed project would result from construction. Impacts associated
with construction activities are short term in nature and not considered
significant. Construction activities would not be allowed during night
hours.
Noises associated with the operation and maintenance of transmission
lines and substations are minimal. Substation noises are caused by
vibration induced in the laminated cores of transformers as a result of
the alternating magnetic flux field. Cooling fans may emit high
frequency noise. However, fan noise rarely contributes to the overall
noise level of the transformer. Other substation noises are the result of
maintenance vehicles frequenting the site approximately once or twice
weekly. A screened chain link fence ten feet in height would enclose the
substation. This fence would help attenuate noise generated at the
substation.
4.8 ELECTRICAL AND MAGNETIC FIELD EFFECTS
Power lines, appliances, motors and wiring ir. houses, like all electri:al
devices and equipment, produce electric and magnetic fields (E/MF).
Electricfields are caused by placing a voltage on a conductor. They are
measured in volts per meter (V/M) or for stronger fields, in kilovolts per
meter. Magnetic fields are caused by electrical current flowing in the
conductor. Magnetic fields are measured in units called gauss or
milligauss. Both electric and magnetic fields dissipate rapidly as distance
from their source increases.
Since the early 1970's concerns have surfaced about long term hazards
caused by E/MF. Numerous studies have been conducted to determine
the existence and extent of health effects caused by E/MF. Overali these
studies have shown that there is no evidence that E/MF produced by
electrical transmission lines pose a health threat to humans or animals.
125L:(4i$9) FR'SS 37
Reviews by the U.S. Environmental Protection Agency, other federal and
state agencies, and individual researchers support this conclusion. A
review by the World Health Organization concluded that electric and
magnetic fields from transmission lines of 400-8OOkV do not constitute a
dangerto human health.
Electricfield effects, such as induced current, voltages or magnetic fields
are directly related to the voltage level of the transmission line. Effects
observed by laboratory studies have been associated with voltages much
higher than the proposed transmission line. At 60kV, the strength of the
electric and magnetic fields is low enough that field effects are
negligible.
No national standards or regulations exist specifically limiting E/MF from
electrical transmission lines. Six states and one city have adopted
standards or guidelines for electric fields. The transmission line voltages
regulated under these standards are all much higher than the proposed
60kV line.
Due to the low voltage of the proposed transmission line, no effects on
radio or television signals are expected.
Impacts and Mitigating Measures: No conclusive evidence exist's that
points to the likelihood of impacts from E/MF, especially for low voltage
transmission lines like the one proposed. Nonetheless, weighting factors
for alternative route selection received high consideration for
transmission line proximity to residential areas.
Should unexpected disruption to radio and television signals caused by
the transmission line occur, the City of Lodiwould mitigate the problem.
4.9 VISUAL RESOURCES
The proposed transmission line poles would be approximately 65 -feet
tall. At the base, the poles would he about twenty inches in diameter.
The insulators holding the conductors would extend about three feet
I'5L_(4;$9) FR. SS 38
from either side of the wooden poles. Typical structure drawings are
shown on Figure 1 in Section 2. The length of the preferred transmission
line route is 1.6 miies. Route 2 would be approximately 2.03 miles in
length.
The project area presently contains man-made facilities that impose a
variety of patterns and contrasts upon the landscape. These existing
structures include overhead eiectrical transmission, distribution, and
communication lines. Other air space intrusions consist of outdoor
advertising signs, highway and railroad crossing signs, industrial
buildings, the City water tower, and other facilities of various size.
The low topographic relief of the San Joaquin Valley does not allow
transmission lines to be screened by natural features. Native and
domestic vegetation is of low height and density so as to provide
intermittent screening of structure bases only. Therefore, the contrast of
the vertical structures and aerial horizontal lines of the conductorswouId
be evident to the foreground and middle ground views in the project
vicinity. No designated scenic routes are within the study area.
impactsand Mitigating Measures: The addition of the transmission line
structures to the existing visual setting of the area would be a residual
impact, evident during the entire lifetime of the facilities. However, this
impact is being introduced into an industrial area slated for more
development and is compatible with the area's land use. With the
exception of the line segments along railroad and the agricultural areas,
all of the proposed routes are along existing or platted roads. Therefore,
the line would be seen mainly by persons living and traveling along the
roads.
Single wooden polesthat represent narrow profile would be used. This
would help to minimize visual effects.
Additional action to be taken to mitigate visual impact of the project
would be screening the substation from view by a screened type chain
link fence.
125L:(4/89) FR ss 39
4.10 CULTURAL RESOURCES
Consultation \Aiith the Central California Information Center (Appendix
4) has indicated no recorded archeological or historical cultural resources
are ;ocated within the specific area of the project. However, there are
four recorded cultural resource sites within a one mile radius of the
project area. Additionally, three sites located within the general vicinity
of the project have been nominated to the National Register of Historic
Places. This information has been forwarded to the California State
Office of Historic Preservation (SHPO) for their review.
Impacts and Mitigating Measures: A letter from the Native American
Heritage Commission (Appendix 4) advises cultural resources have been
discovered at other projects at depths greater than eight feet. The entire
project area has been disturbed by either agriculture or other land uses.
in the event that cultural or historic remains are discovered during
construction activities, ail work in the area of the find will cease and the
City of Lodi will immediately notify the California SHPO to solicit
mitigation recommendationsfor appropriate action.
Once a preferred route and substation site alternative have been chosen,
a Class III archaeological field reconnaissance would be conducted for
these locations.
4.11 SOCIO -ECONOMICS AND COMMUNITY RESOURCES
The economic base of the area is the processing and delivery of the
agribusiness products of the surrounding rural area. Lodi also serves as a
bedroom community for many residents who commute for employment,
primarily to Stockton or Sacramento, and more recently the Bay Ares.
The major employers in the Lodi labor market area, which includes nearly
75,000 persons, are General I'fills, Goehring Meat, Inc., Pacific Coast
Producers, Holz Rubber Company, Guild Winery, Valley Industries, and
Dart Container Corp. The recently completed expansion by General Mills
1251 (4:89) GR is 40
represents substantial and reliable productivity.
Major non -manufacturing employers include: Lodi Unified School
District, Lodi Memorial Hospital, Lodi Community Hospital, The City of
Lodi, Farmers and Merchants Bank, Pacific Telephone, and Mervyns
Department Store.
Social and economic impacts resulting from implementation of the
proposed action would be positive. The contractor performing
construction on the facilities would be encouraged to hire local labor,
while the goods and services pertinent to construction personnel and
operations (e.g., motels, restaurants, service stations, and recreational
facilities) as well as sundry construction materials would be purchased
from the local commercial sectors, thereby further bolstering- the area's
economy. Ail contractors and subcontractors must be equal opportunity
employers. Probably the most significant impact of the proposed
construction would be the positive impact that a more adequate and
reliable energy supply would have on the lifestyle and iivelihood of the
City's consumers. Existing income producing operations may be
expanded or utilize more modern technological methods; opportunity
for new industry may be enhanced. Consumers would be assured of the
qua!ity of electric service.
Impacts and Mitigating Measures: The potential impacts of the
proposed transmission line on population and income are indirect. Yet
the transmission line could have secondary impacts by removing an
obstacle to population growth thereby allowing development at general
planned densities.
4.12 LAND USE
Land use adjacent to the alternative routes includes residential,
commerci�;', industrial, transportation, and agricultural uses. Each of the
routes minimizes contact with residential areas. Agricultural uses include
row crops, pastures, vineyards, orchards and wineries. Most of the
project area located in the county is zoned I -PA (Interim Protected
I251:(4,89)FR:ss 41
Agriculture), although a small section is zoned Limited Manufacturing
(M-1).
The portion of the alternative routes that are located within the Lodi City
limits are zoned M-2, Heavy Industrial.
Over the past ten years, the City of Lodi has also been faced with the
issue of controtling expansion and growth of residentiai and other uses
whiie protecting the agricultural lands. In an effort to control and plan
for future development, the city enacted legislation by which any parcel
of land to be annexed into the City would require a majority vote of the
electorate. This action is intended to improve the quality of the
environment for the residents and serve to protect agricuitural land use
by retaining land in agricultural production.
Impacts and Mitigating Measures: The project as proposed would take
approximately ten acres out of agricultural production; subsequently
being replaced with transmission poles and substation facilities. If
alternate route 2 were chosen, approximately 10.1 acres would be
removed from agricultural use. To ensure as little an impact as possible
upon agricultural activities, the structure placement would use property
lines, railroad, street and road corridors as much as possible.
5.0 EVALUATION OF ALTERNATE ROUTES
This section draws a comparison between the preferred and alternate routes,
and also to the environmental concerns and potential impacts described in
Section 4.0. Alternate routes are shown on the project area map in Appendix
6. The Route Evaluation Worksheet provides the basis for this evaluation and
comparison of alternatives.
5.1 COMPARISON CF ALTERNATE ROUTES
Based on the the two preceeding sections (3.0 and 4.0) in which the
routes are evaluated, analyzed arid ranked, and environmental impacts
1251.!4:89; FR: SS 42
are illustrated, one preferred route and one alternate route are
recommended. Both routes are described below and are compared in
Appendix 2, Table 3, Alternate Routes Total and Ranking.
As stated in section 3.0, criteria were developed to evaluate potential
routes and substation sites. These evaluation, criteria (listed in Appendix
1) represent the engineering, land use, and environmentai concerns
present within the study area. Each criterion is assigned a relative value
of importanceor weighting. These weights range in value from 5, which
representsa high potential for conflict and/or costto -3, which represents
a positive impact and/or low cost. When the weighting is multiplied by
the number of occurrences along a given route segment or link, the
resulting score reflects the compatibility of the link with the specific
criterion. This assumes that all occurrences relative to each criterion are
of equal value. When the links are combined and totaled, the route with
the fewest cccurrencesand lowest numerical score is considered the best.
Appendix 2 contains all route and site evaluation worksheets and a
summary sheet representing the preferred route. The reader is
encouraged to refer to the project area map in Appendix 6 to visually
connect the route descriptions that follow.
5.1.1 Preferred Route = Route 1 (links 1.1, 1.2, 1.3, 1.4, 1.5, 1.6)
LINK 1.1:
This route has a total distance of approximately 7.6mileswith an
estimated 17 landowners located along the total length. The
route begins at interconnection A, east of existing pole 5/10
located inthe Lockeford-Lodi No.2 60kVtransmission line, which is
east of the Guild Winery. From the tap point, the line would
extend in a southerly direction along the west side of the Central
California Traction Company (CCTCo.) Railroad, which has a ± 50
foot right of way width.
1 25L. (4189) FF, Ss 43
A portion of this line would be underbuilt with 12.5kV distribution
in order to serve a pump owned by the City of Lodi. The pump is
located ± 1,400 feet south of the takeoff point. There is a young
cherry orchard west of the railroad beginning just south of the
service drop to the pump.
The total length of this link is 2,720 feet requiring a 40 foot wide
right of way, or approximately 2.5 acres.
LINK 1.2:
At the point where link 1.2 would turn west, there are problems
with guy placement to make the right angle turn. They may be
solved by using a slack span or self-supporting tubular steel pole.
From link 1.2, which occurs at the northern edge of the San
Joaquin Warehouse, an alternative route that continued south
along the railroad across Highway 12 was considered but clearance '
was restricted bytwo brick buildings thereby making the route less
desirable.
Link 1.2 alignment follows a property line and field edge in a
westerly direction to Guild Avenue (formerly Myrtle Road). North
of the property line is a vineyard and apple orchard; south of the
line is vacant land. The line would be underbuilt with distribution
700 east of Guild Avenue in order to serve a well; however, the
well itself may have to be relocated due to its dose proximity to
the proposed electrical line.
The length of link 1.2 is 1,340 feet requiring a 40 foot right of way,
or 1.23 awes.
LINK 1.3:
Link 1.3 would turn south at Guild Avenue and proceed to
Highway 12. A distribution underbuild would occur for the two
spans across the Southern Pacific Railroad a^:d State Highway 12.
1 ? 5l: (4.89) FR: sz 44
At the State Highway 12 crossing, it may be necessary to remove a
minimum of one tree and to lower the existing distribution line
along the south side of the highway for at least two spans. A
number of the trees are in the CALTRANS right of way; they have
indicated permission would be granted for minimal tree removal.
This alignment would have 700 foot total length, and require 0.64
acres of right of way.
LINK 1.4:
Area developers have received permission from the City of Lodi to
exten . Guild Avenue south from Highway 12 across Pine Street to
the C -Co Railroad. Along this alignment, the electrical line
would be located on the east side of the proposed street to avoid
the small, zero setback industrial lots that have been piatted on
t he west side.
Along the link 1.4 alignment for the proposed extension of Guild
Avenue, halfway between Highway 72 and Pine Street, Dart
Container Corp. maintains a booster water pump for fire
suppression. It is enclosed in a cinder block and sheet metal
building approximately 12 feet by 18feet, and is 10feet high. The
building is located ± 2 feet from the property line. Also located
approximately 12 feet with inthe northwest corner of the property
line is a fuel pump, which is used to fuel Dart vehicles. in order to
meet National Electric Safety Code (NESC) clearance, horizontal
post insulators all placed on one side of the pole, called vertical
construction, would be utilized in this area to clear the building
and gas pump. This link would continue along the east side of
future Guild Avenue in a southerly direction until crossing Pine
Street. This link segment is ± 1,300 feet in length, requiring a 2
foot overhang encroachment onto private property.
1251:(4•'89) fR:ss 45
LINK 1.5:
On the south side of Pine Street, link 1.5 would meet an existing
4kV distribution tine. The line would be underbuilt with
distribution in order to serve a pump at the Lodi Memorial
Cemetery and other customers south of CCTCo. HOri7ontal post
insulator construction, or vertica! insulator configuration, may
have to be used to avoid a well that is housed inside a shed located
on the cemetery property adjacent to the west property line. The
proposed Griffin Industrial Park to be located on the west side of
the future Guild Avenue has been platted for small, zero setback
lots. The proposed routing alignment would be on the east side of
Guild Avenue to avoid these lots, and would require a 2 foot
overhang encroachment onto the cemetery property. Although
the structure placement would occur on the east side of the
cemetery fence, construction would not disturb any existing or
future grave sites. Link 5 is ± 1,240 feet in length.
LINK 1.6:
Link 1.6 would cross the future extension of Lodi Avenue and the
CCTCo, a distance of 100 feet, and would follow along the
railroad's south side for a distance of 1,190 feet. This alignment
would avoid the congestion at Link 1.6.1 by crossing CCTCo at the
west side of the cemetery. Substation site, 55-2, would be located
on the south side of CCTCo. Alternative substation site, S5-1,
would be located to the west of SS -2, in which case the route
would then continue in a westerly direction and would overbuild
an existing distribution lineto a proposed substation site, SS -1.
LINK 1.6.1 (Alternative to 1.6 link):
Link 1.6.1 would follow the south side of the future extension of
Lodi Avenue and the north si(: of CCTCo in a westerly alignment
currently occupied by the Lockeford-Lodi No. 3 60kV line; a
distance of 1,120 feet. This alignment would require the
I25L:' S9) FR:ss 46
placement of an additional circuit of 60kV line, which would
parallel the existing Lockeford-Lodi No. 3 line.
At the east side of Cluff Avenue, the line would extend for 230 feet
in a southerly direction across the CCTCo to proposed substation
site, SS -1.
5.1.2 Alternate Route 2 (links 2.1, 2.2, 2.3, 2.4, 1.5, 1.6)
LINK 2.1 :
This alternative rout? would have a takeoff point from the
Lockeford-Lodi No.: 60kV line located northeast of the City.
Takeoff point B woL Id occur at a point between existing poles 5/4
and 515, which would be in the middle of a field of cultivated row
crops. From the takeoff, the route would extend south within the
river's Floodplain Zone A14 (100-yearflood boundarywithin which
base flood elevations and flood hazard factors are determined) for
approximately 1,120 feet across a field of row crops. The first two
structures would be placed in a diagonal alignment across the
field. It may be necessary to place a guy toward the Mokeiumne
Riverwithin the primary containment levee to reach the top of the
bench. A 40 foot right of way would be required for a total of 1.03
acres.
LINK 2.2:
Upon clearing the Floodplain Zone A14, this link would then
extend in a southerly direction along a private farm road, which
lies within FEMA Flood Zone B (a 500 -year flood boundary).
Vineyards are present on the west side of the road, with vacant
land on the east side of the road.
This lint, would continue south and cross the Southern Pacific
Transportation Co. Railroad (SPRR) and Highway 12 at the location
of an existing distribution line. It would probably be necessary to
125 UW'89) FR. ss 47
remove an existing tree in the CALTRANS right of way as part of
the crossing permit. The length of this link would be
approximately 1,830 feet, requiring 1.68 acresof new right of way.
INK 23:
From Highway 12 to the east end of Pine Street, the route wou!d
follow existing property lines and a field road with vineyards on
either side. This link segment would be approximately 1,330 feet,
requiring 1.22 acres of new right of way.
LINK 2.4:
Link 2.4 would :urn west at Pine Street and follow an existing
distribution line. Since Pine Street is only 40 feet wide in this area,
some guying and clearance problems would be encountered.
There are three houses on the southeast corner of Pine Street and
Curry Avenue that may force vertical clearance construction, to
avoid clearance problems.
From Curry Street to the extension of Guild Avenue, ± 3,300 feet,
the line would be underbuilt with an existing distribution line,
which runs along both sides of the street. The total length of link
2.4 is 3,740 feet.
As the line turns south at the cemetery at Link 1.5, a slack span
would probably be required to avoid a stub and guy on the north
side of Pine Street. From this point, the alternative route would
follow the same alignment as Route 1.
5.2 Comparison of Substation Sites
Two sites near the City's industrial area have been considered for the
new 60-12kV substation. Both locations are acceptabie and a preferred
site has not been designated at this time.
, z_ L.;4.1s9I FR:ss 48
5.2.1 Substation Option SS -1
This site is located at the southeast side of Lodi Avenue and Cluff
Avenue, south of the CCTCo railroad. The site is currently occupied
by an older residential dweliing and vineyards. The site is iocated
in San Joaquin County and is zoned I -PA (Interim Protected
Agriculture). The County would allow a ten acre parcel to be
developed bythe City for use asa publicfacility.
Immediately north of SS -1 is PG&E's Lockeford-Lodi No. 3 60kV
circuit. Siting a substation at this location would allow for easy
access since Lodi Avenue is directly north, and the proposed
extension of Thurman Street is directly south.
5.2.2 Substation Option SS -2
SS -2 is located approximately 1,200 feet east of SS -1 on the south
side of CCTCo railroad. The site is currently vineyards zoned I -PA in
the County.
Although the City plans to extend Lodi Avenue in an easterly
direction and Guild Avenue in a southerly direction, currently
there is nopublic accessto this parcel.
The SS -2 site would require additional 60kV and 12kV line lengths
to connectthe substation to the City's electrical lines.
6.0 ENVIRONMENTAL CONSEQUENCES
6.1 SIGNIFICANT AND UNAVOIDABLE ENVIRONMENTAL EFFECTS
As stated previously in this document, there are no significant
environmental effects associated with the City of Lodi's 60kV
transmission lineand substation.
125L: (4189) FR:ss 49
No potentially significant impacts such as effect upon agricultural
activities, existing high density residential and commercia! areas, cultural
resources, wildlife habitat, wet:ands or other environmental factors were
identified. Thetransmission linewould have residual impact to the visual
setting for the lifetime of the proposed facilities, but the preferred
alternative is in an industrial area with varied and contrasting man made
features already in existence. Although no evidence exists that any long
term effects would result from electric and magnetic fields associated
with the transmission line, route selection was weighted heavily to avoid
residential areas.
Public comment would be received subsequent to releasing the Draft EIR.
Public comment would be addressed and incorporated into the Final
Environmental Impact Report and factored into the overall project
eva luatton.
6.2 MITIGATION MEASURES PROPOSED TO MINIMIZE THE ENVIRONMENTAL
EFFECTS
Types of impacts were first identified by considering what effects
activities associated with the proposed action could have on the pre -
project environment. Each alternative corridor identified for the project
encompasses a 40 foot wide right of way. Potential imparts occurring
along the right of way were analyzed and evaluated in Section 3, tables 1
and 2; examined in Section 4, and summarized in Section 5. Mitigating
measures were also identified within each environmental category and
were specifictothe impactdiscussed in Section 4.
6.3 THE RELATIONSH I P BETWEEN LOCAL SHORT-TERM USES OF MAN'S
ENVIRONMEt'4T AND THE MAINTENANCE AND ENHANCEMENT OF LONG-
TERM PRODUCTIVITY
For purposes of this section, short-term has been defined as 35-40 years
(the estimated life of the proposed project!, and long-term as the period
thereafter.
12 5 L. (4i89) FR: ss 50
Within the life of the project, the construction phase would represent
the period of greatest environmental impact for the preferred 1.6 miles
of 60kV transmission right of way and a substation site.
Construction within the preferred corridorwould result in disturbance to
approximately 7.95 acres for transmission structures and tine installation
,_.nd ten acres for installation of the new substation and associated
facilities.
Following the construction phase OT the project, the majority of th a land
disturbed would begin to revert to its preconstruction use. At each
location an approximate 2,000 square foot area wouid be temporarily
disturbed by the construction, this disturbance would include
construction vehicle access. Rehabilitation would be conducted on tris
area as needed. The total area to be occupied by the typical tangent
single pole structure would be approximately 4 square feet.
Most resources within the physical, biological, human, and cultural
environments would experience short-term impacts resulting from
construction activities. Long-term effects and productivity would
depend on the continued existence of the proposed project's facilities, or
the continued use of the right of way asa utility corridor.
6.4 SIGNIFICANT IRREVERSIBLE ENVIRONIIAENTAL CHANGES AND
COMMITMENTOF RESOURCES
Resources committed to the proposed project would be material and
non -material, and would include financial resources. Irreversible
commitment of resources for the purpose of this section have been
interpreted to mean those resources that are committed to the project
and would continue to be committed throughout the estimated 35-40
year life of the project, and beyond as the line would remain in service as
long as electricity to the City's subject areas is required.
City utility resourceswould be required to extend water and sewer lines
to the substation control house. In addition, the extension of Thurman
17.51:(4%89) FR. SS 51
Street from Beckman Road easterly approximately 1,300 feet would
satisfy the preferred access to SS- 1.
Irreversible commitment of resources would apply to biological and ,
visual resources. Biological resources would be irreversibly committed
due to the disturbance and loss to vegetation and agriculture during
construction and operation. Visually the line would represent a residual
impact to the developed and industrialized project area.
6.5 GROWTH INDUCING IMPACTS
Growth inducing impacts resulting from construction of the proposed
project would not directly foster economic or population growth.
Residential and industrial subdivisions, and any future annexation
impacts must be assessed when long-term needs are considered, and
water, sewer, roads, and electricity eventually provided. The project
would help provide adequate, reliabte electric service to these steadily
growing areas.
The areas of Lodi that the project is proposed to service are areas that
have steadily increasing populations and industrial development. Despite
the fact that annexation initiatives continue to be defeated, thereby
precluding the need for immediate community services for new property,
the growth and expansion of existing industrial developments continue
to occur.

APPENDIX 1
ROUTE & SITE EVALUATION
CRITERIA DEFINITIONS
POWER Engineers, Incorporated
APPENDIX 1
ROUTEAND SITE EVALUATION CRITERIA DEFINITIONS
This appendix discusseseach of the criteria the routing team developed to evaluate
alternative points of the transmission line routes and substation sites. These criteria
were used for identifying general land use, engineering, and environmental
conditions that pose constraints to routing a transmission line and siting
substations. Weight assignmentsfor these criteria, commensurate with the degree
of conflict and/or cost, are also reviewed. This appendix is divided into two sections
with three main categorieseach: a section each for transmission line and substation
with each section addressing land use, engineering, and environmental
considerations.
1.0 TRANSMISSION LINE EVALUATION CRITERIA
1.1 LAND USE CONSIDERATIONS
Number of buildings requiring removal or relocation. Pursuant to the
California Relocation Act, this addresses the greatest direct impact of a
transmission line, particularly from economic and social factors, and
therefore was assigned a weight of 5. As presently envisioned with a
forty (40) foot right of way, the preferred alignment would not require
buildings to be relocated.
Per thousand feet of line rrquirir.1 .r .-a- esto,ation effr -ts. Within
environmentally hardened urban areas, transmission line construction
activities may require restoration of storm drains, curbs, sidewalks,
parking lots, and decorative landscaping. A weight of 3 was assigned for
each 1,000 feet affected.
Per thousand feet crossing agricultural land on a diagonal. Transmission
lines impose special constraints upon agricultural practices, especially
when routed at an angle to practical patterns. Such alignment creates
undue hardship upon operators of farming machinery and aerial
spraying applications. This criterion is considered a severe constraint and
t 25L. mam (4/89)
has been weighted a 5.
Per thousand feet along field edge. While this proximity to agricultural
operations imposessome problemsto the operator, a field edge location
is less restrictive than open field or diagonal rerouting. Therefore, this
criterion is weighted a 2. This criterion excludes frontage for houses,
barns, and commercial developments.
Per thousand square feet in conflict with land use planning goals. This
criterion, given a weight of 5 is consistent with the Williamson Act and
the San Joaquin County planning goal to protect agricultural land from
incompatible uses. Relative to that goat, transmission line poles would
directly withdraw land From productive uses by approximately 4 square
feet per pole, or a cumulative total of 100 square feet (0.0023 acres)
along the preferred route.
1.2 ENGINEERING CONSIDERATIONS
To ensure that the route ultimately selected for construction is feasible
for transmission line constructiori and maintenance, a number of factors
relating to design and construction were considered. Listed below are
five engineering considerations used inthe evaluation of the routes.
Per thousand feet of line. No other single factor contributes more to the
cost of the . 3nsmission line than its length. Therefore, this criterion
received a weight of 5.
Per thousand feet requiring new construction and maintenance access.
Difficult or poor access requires special construction techniques and/or
extended construction time. When these areas also require road
building to aid in constriction access and maintenance activities,
reseeding or revegetation is often required. A weight of 5 was assigned
to this factor.
Per thousand feet of line of existing distribution/communication of other
„tiiitit, . Special engineering allowances have to be made when a
25L:mam (4;89)
distribution line is paralleled. If the transmission line is to be built
alongside the existing distribution line, then additional right of way is
required to provide adequate clearances. If the new line is built where
the distribution is located, then the distribution line must be relocated in
one of three ways: on the new structures (underbuild), below the new
structures (underground), or on the other side of the road. In this
instance, the distribution underbuild option would have a positive
impact on the transmission iine routing since existing right of way may
be used and the visual impact created by adding a second pole linewould
not be increased. Therefore, this factor was assigned a weight of minus 3
(-3).
Per thousand feet alonq poorly drained, floodplain, wetland areas.
Special structure foundation designs with higher associated costs may be
required for these areas; therefore, a weight of 5 was assigned.
Number of angles greater than 60 degrees. Large angles have a higher
cost because they require special structure design. A weight of 4 was
assigned to each occurrence of this factor. For the routing of the
alternatives, the angle of structures was estimated, final determination
of angle degreewill occurduring design.
1.3 ENVIRONMENTALCONSIDERATIONS
The four environmentai considerations discussed below were selected to
determine the degree of environmental conflict posed by the
transmission line route location.
Number of cultural resource conflict areas. Sites of archaeological and
historic interest and significance are to be avoided. A weight of 5 was
assigned each time the line would pass over or adjacent to a cultural
resource. While not an apparent issue, this criterion retained to
demonstrate its consideration.
Perthousand feet of line through sensitive wildlife habitat. Areas such as
stream crossings, ponds, wetlands, abandoned fields, or pasture with
125,, nam (4;89)
native vegetation provide habitat for a variety of piant and wildlife
species including threatened or endangered-pecies. These areas are
assigned a weight of 5 for each thousand feet of occurrence.
Perthousand feet requiring tree trimminq and/or removal. Orchards and
various, species of shade and ornamental trees are a valuable resource in
an area otherwise devoid of trees; taller trees also provide a screening
effect for the transmission line structures. Therefore, protection of trees
is an important project consideratior, and removal or tree trimming is
weighted a 5.
Number of residences within 100' of R/W exposed to electrical and
magnetic fields. While the present research on biological effects of
electric and magnetic fields is inconclusive, the criteria represents
consideratior!ofthis issue. Even though the relatively low voltage of the
tine and the field effects of the proposed line would be below any
established standard, either at the right of way edge, or within the right
of way, the criterion is weighted a 5 to demonstrate a sensitive response
to public concerns.
2.0 SUBSTATION SIT= EVALUATION CRITERIA
2.1 LAND USE CONSIDERATIONS
Number of buiidings requiring removal or relocation. Pursuant to the
California Relccation Act, this isthe greatest direct impact of a substation
inthis category and was assigned a weight of 5.
Number of private land parcels affected by acquisition. The right of way
process becomes increasingly involved as t, ie number of parcels of land
and potential landowners affected by a substation site increases. A
weight of 2 was assigned to this factor to account for additional
negotiation and settlement proceduresthat may be required.
Df�te construction impacts. The proximity of other iand uses and ?he
potential for their destruction during construction is a measure of a site's
125L.rnam (4189)
overall ability to accommodate development. This crirerion is weighted a
2.
Long term effect3 on adjacent land uses. This criteria considers the effect
of a substation on present and future land uses, and the perceived
limitation on potential development. Included in this criteria is a
consideration of eiectric and magnetic fields emanating from the
substation. The criteria is weighted a 2 to account for possible
cumulative long term effects.
Siting on cultivated cropland. Siting of a substation on cultivated
cropland can potentially take 3 acres out of production. Such action
would be inconsistent with the Williamson Act and Sar, Joaquin County's
planning goals. The location of a substation in the corner of a field may
pose an obstacle to maneuvering farm equipment and reduces the
flexibility in cropping patterns. For these reasons, a weight of 5 was
assigned to this factor.
2.2 ENGINEERING CONSIDERATIONS
The following lists three engineering considerations that were used in
the evaluation of the substation sites.
Difficulty of site preparation. Weighted a 2, this criterion is a measure of
a site's physical characteristics, such as slope, drainage, accessibility, soil
bearing capacity, etc., and the degree of difficulty they may impose on
substation construction.
Acquisition cost. A parcel's size and shape will dictate to some degree
the arrangement of substation facilities, and the ability to logically
expand the substation to accommodate future needs. Acquisition costs
were determined by recent, comparable costs for industrial zoned parcels
within one-half mile of the proposed sites. This criterion isweighted a 4.
125L mam (4.89)
Ease of existing access. Existing access to the proposed substation sites
was considered for this factor. The City of Lodi intends to extend
Thurman Street for the eventual, permanent access. However, at this
time, an existing frontage lane south of Lodi Avenue and CCTCo wouid
be the only access, therefore, this criterion was weighted a 1.
2.3 ENVIRONMENTALCONSIDERATIONS
The four environmental considerations discussed below were selected to
determine the degree of environmental conflict posed by substation
siting.
Number of cultural resource conflict areas. Sites of archaeological and
historic interest and signif;cance are to be avoided. Thus, a weight of 5
was assigned each time a substation would be sited within 1/4 mile.
While not an apparent issue, this criterion is retained to demonstrate its
consideration.
Area of sensitive wildlife habitat. Areas such as ponds, wetlands,
abandoned fields, or pasture with native vegetation provide habitat for
a variety of plant and wiidlife species. Sites in these areas are assigned a
weight of 5 for each site located thereon. While not an apparent issue,
this criterion is retained to demonstrate As consideration.
Visually prominent from a statelfederal highway. To mitigate the visual
impact of a substation to travelers of major highways, sites were chosen
within an existing industrial area and well away from major travel ways,
therefore this criterion was assigned a weight of 3.
3.0 ROUTE ANC 3t.1BSTATION SITE POINT RANKING
The total scores within each of the two major criteria categories were used to
determine rankings. The route with the lowest total score received a ranking
of 1. The alternative substation sites were weighted but not ranked at this
time.
125, mam (4 89)
4.0 THE PREFERRED ROUTE
The route with the lowest score represents the preferred route a'ccording to
the evaluation criteria. A preferred substation site has not been identified.
Route 7 isthe preferred routewith a total score of 63.72. Shown In Appendix
2, Table 3, Route 1 offers the optimum balance between design/construction
costs, land use, and environmental concerns.
This route displays the best overall compatibility with the analysis criteria.
Section 5.0 compares the preferred route and alternate route, and describes
the positive and negative aspects of each.

NOTICE OF PREPARATION
CITY OF LODI INDUSTRIAL SUBSTATION E I R
PROJECT STUDY AREA
The City of Lodi is proposing to construct an electric substation and
related transmission lines east of the City of Lodi. An E I R will study
the substation site located south of Lodi Avenue and east of Cluff
Avenue, as well as various routes for the transmission lines. The
study area will be roughly the Mokelumne River to the north,
Curry/Kennison Road to the east, Industrial Way to the south and
Highway 99 t o the west.
PROJECT
The City of Lodi is proposing to .construct a rew electrical substation
that will be called "Industrial Substation." The facility will be
located in a future industrial area east of the City. The sites under
consideration for the substation are south of Lodi Avenue and east of
Cluff Avenue. This area is currently outside of the City limits and is
planted in vineyards. The areas to the north, west and south are
undergoing industrial development. The substation w i I I require
approximately three acres.
In addition to the substation, the project will require the
construction of new 60-kv lines connecting the substation with existing
electrical facilities. There will be t,;o connections to existing PG&E
transmission lines. One line will connect with the Lodi- Lcckeford No.
2 line that runs along the Mokelumne River. The second connection will
be to the Lodi-Lockeford No. 3 line that runs along Lodi Avenue/Sargent
Road. The specific route of these connecting lines will be analyzed as
a part of the EIR.
There will also be two new lines connecting the substation to the City
of Lodi distribution loop located west of the substation site. These
lines will be located within existing City easements and right-of-ways.
The Industrial Substation will consist of a 60-kv switchyard with eight
60-kv positions (i3 breakers total) and space for one future 60-kv
position on the west end. The three eastern positions will provide for
termination of three PG&E 60-kv lines, and the western position will
provide for the termination of three City of Lodi 60-kv lines and two
60/12kv transformer positions.
In addition to the 60-kv switchyard, the substation will include a
12-kv yard with two 60/ 12-kv transformer positions and space for a
third 60/ 12-kv transformer position.
POSSIBLE IMPACTS TO BE INVESTIGATED
i . Disruption, displacement or compaction of soil?
Soil disruption will occur on a localized basis as a result of
auguring holes fcr directly imbedded poles, or from excavations
required for pole and substation structure foundations.
Some soil compaction may occur as a result of construction
vehicles traveling along the right-of-way.
2. Change in air quality or create substantial air emissions?
The construction activity has the potential to create dust
problems in the immediate vicinity of the work. Both the movement
of construction vehicles along the line routes and the actual
digging and grading at the construction sites can produce
short-term dust problems.
3. Increase in existing noise levels?
The construction activity may result in an increased noise level
primarily from construction vehicles. The problem will cease once
construction is completed.
4. Effects on agriculture?
The substation will require removal of approximately three acres
of vineyards from agricu?tural production. The transmission poles
will be placed along road or railroad rights-of-way and should not
require the removal of any agricultural land.
Depending on the route selected for the 60-kv interconnect line
between the substation and the PG&E Lodi-Lockeford No. 2 line,
some adjacent agricultural operations could be affected.
Placement of new poles and lines along the edge of fields could
affect current patterns of crop dusting.
5. Visual impacts?
The placement of new poles
and lines
could affect the visual
setting of the area. The
poles could
be as
high as 65 feet and
would be visible from the
surrounding
area.
Depending or, the
route, the new line could
be located
along a
route that. already
has a pole line. In this
case the new poles
would replace the
existing poles.
The subject area is an industrial area. There are industrial uses
both within the City limit; and in the County. Much of the
current agricultural areas will bp developed with industrial uses
sometime in the future. There are also existing power lines along
every street and road, including the existing PG&E 60-kv lines.
Ail these man-made features have already impact-' the visual
landscape of the area.

QF3 ECTIPITERCONNECIIQN r RaJECI
Dear Mr.Morimoto:
GEORGE DEUKMEJIAN. Governor
The concern of the Native American Heritage Commission is in those
places where the prehistoric sites underlie areas which have been previ-
ously developed and thought to be free of cultural resources.
One problem which takes p!ace regularly throughou; the state involves or-
chards and vineyards, such as the three acres where the substation wi!I be
placed. When either of these two are phased out and there is a change of
crops, cultural resources under these areas become adversely impacted.
The root structure goes down into the archaeoiogical sites.
Due to the long habitation of that region by various Indian tribal groups
over extended periods of lime, thousands of years, the likelihood of dis-
covering previously undetected cultural resources is a very real possibil-
ity which should be addressed in any environmental document.
Native American cultural resources have been discovered at depths in ex-
cess of eight feet on some recent projects. A buildup of siit over long
periods of time have provided a buffer of safe cover between the tops of
the archaeological sites and the existing grade. Some had been built upon,
still others had been used for agricultural purposes, as in this case. All
had been thought to be free of cultural resources.
The California Environmental Quality Act, Appendix K, deals with the dis-
covery of archaeological sites and the procedures to follow. It also con-
tains the instructions to follow when human remains are found during any

Power Engineers Incorporated RE: File #0946L
P.O. Box 1066 1345-0.24;City of Lodi
Hailey, Idaho 83333 Electrical Transmission Line
As per your request we have conducted a records search for the above -
referenced project area located on the Lodi North, Lodi South, Lockeford
and Waterloo 7.5 -minute U.S.G.S. quadrangle maps. We have conducted
the records search for the specific project area and for the general
study area as outlined on the maps you provided.
According to our files there are no recorded archaeological or historical
cultural resources located within the specific environs of the project
or within the project study area. The specific environs of the project
and the study area boundary include no areas that have been subject to
previous cultural resource investigation. For your information, within
a one -mile radius of the project study area, there are four recorded archaeo-
logical cultural resources (Native American Indian occupation and burial
sites) .
According to the National Register of Historic Places, there are three sites
nominated to the National Register within the general vicinity of the project
and study area, listed as follows:
Lodi Arch (Mission Arch; Pine Street) Ref. No. 80000848 (west of study area).
Morse -Skinner Ranch House (13063 N. California 99); Ref. No. 86001878
Terminous Culling Chute (Tower Park Culling Chute; 14900 W. California 12);
Ref. No. 54001180
Since the project area and study area environs have not been subject to previous
cultural resource investigation, it is possible that unrecorded archaeological and
