Less Than Significant Impact. The proposed project is required to comply with the National Pollutant Discharge
Elimination System (NPDES), the General Pen -nit for Storm Water Discharges Associated with Construction, and other
applicable portions of the federal Clean Water Act, including the Porter -Cologne Water Quality Control Act, or Section
401. Also, the City of Carlsbad has adopted a Storm Water Management and Discharge Control Ordinance. This
ordinance requires that all new development and redevelopment activities comply with the City's adopted storm water
pollution protection requirements. The subject project is not exempt from Standard Urban Stormwater Management Plan
(SUSMP) requirements and is considered a Priority Project, requiring Priority BMPs. The project applicant is also required
to submit a Notice of Intent to the State Water Resources Control Board, prepare a Stonnwater Pollution Prevention Plan
(SWPPP) and implement BMPs detailed in the SWPPP to reduce construction effects and post -development effects on the
downstream water bodies.
The project developer is required to identify and implement: BMPs to reduce impacts to surface water from contaminated
storm water discharges. In accordance with the NPDES, the construction contractor will be required. to comply with
NPDES and SWPPP regarding the implementation of BMPs during construction.
Post -Development BMPs. The sewer pipeline will be placed underground and as a result no substantive post -development
(permanent) BMPs are required. The lift station however will provide site design BMPs through source control and
treatment control in order to protect downstream waters. The primary lift station site design BMP will be the installation of
energy dissipaters such as riprap, at the outlets of the new storm drains that enter unlined channels at the lowest elevation
end (west side) of the lift station site, in accordance with applicable specifications to minimize erosion from the project site.
The energy dissipaters shall be installed in such a way as to minimize impacts to the receiving waters. Also, riprap will be
installed at the outlets of the new storm drains located along the west side of the lift station site that drains to the existing
vegetated bio-swale flow conveyance area and into a proposed water quality detention basin. At least 80% of the "first
flush" of a rainstorm will be treated through this bio-swale and water quality basin. High -volume rainstorms (10-year
storm or greater) will fill up the basin and overflow water will run directly downstream to the lagoon. A separate, elevated

culvert will also be constructed along the eastern perimeter of the lift station structure to eliminate the potential for erosion
along the eastern half of the site.
In addition, the lift station design concept incorporates extensive equipment redundancy for ensuring that equipment
failures do not result in accidental sewage spills. The concept involves a lift station configuration that includes two
independent pumping elements. The "lift" side of the station includes four 40 hp pumps. The "force maid' side of the
station includes four 100 hp pumps. The total pumping capacity of the station is up to 23.5 mgd on the lift side and up to
26.5 mgd on the force main side. The total station capacity is 50 mgd. providing 50% redundancy at peak wet weather flow
conditions (33 mgd) and over 100% redundancy at peak dry weather flows (21 mgd). The force main side and lift side can
independently pump peak dry weather flows (21 mgd). In the event that a total failure occurs on either side, the station
remains operable without consequences under peak dry weather flow conditions, and contains power redundancy and
significant upstream storage capacity under catastrophic circumstances were they to occur under peak wet weather
conditions.
The station is also with two independent electrical circuits (primary and secondary), and will include an automatic standby
transfer switch in the event of catastrophic power failure. In the event of full regional blackout, emergency power will be
provided by a built-in on -site diesel fuel generator. Under such circumstances, the station is designed with alarms to alert
officials to the problem and to enact the contingency plans to reduce flow (upstream lift stations contain storage volume)
under such circumstances, if necessary. The upstream pipe also contains a significant amount of storage capacity to allow
the time necessary to resolve a problem, should it occur.
The lift station site design BMP's will involve a multiple -treatment program, including four different treatment systems, as
indicated below. This information is shown on Figure 12.
1. Vegetated or river rockswale. A vegetated or river rock swale will be located along the southeast side of the project.
This swale will treat runoff from the site through filtering by the vegetation in the channel, filtering through a subsoil
matrix, and filtration into the underlying soils. The swale will trap particulate pollutants, promote infiltration and reduce
the flow velocity of the stormwater runoff. The swale will maintain a thick vegetative cover or river rock to maintain
proper drainage treatment functioning. Inspection and maintenance will be performed as necessary.
2. Wet vault. An underground wet vault structure will be installed along the west side of the project site. This structure
will be on-line, in that it will connect from a storm drain (which collects on -site drainage), treats the stormwater in the vault
(similar to a larCY
ge catch basin), and exits drainage out into another storm drain line. It is designed to provide temporary and
permanent storage for stormwater runoff. The permanent pool of water in the vault dissipates energy and improves the
settling of particulate stormwater pollutants from the site.
3. Pervious surfaces. Pervious surfaces will be utilized over a portion of the lift station site. The pervious surfaces will
capture stormwater and allow it to infiltrate into the ground instead of running off the surface, and off of the site.
4. Infiltration basin. An infiltration basin will be located at the south end of the site. This basin will be designed to
infiltrate stormwater and will use the natural filtering ability of the soil to remove pollutants from stormwater runoff. The
basin will be designed with a minimum soil infiltration rate of 0.5 inches/hour. The basin will be designed to meet City of
Carlsbad standards.
Construction BMPs. During construction, the project BMPs will include, but are not limited to; silt fencing, fiber rolls or
gravel bag berms, street sweeping and vacuuming, covering soil piles, storm drain inlet protection, check dams, stabilized
construction entrances and exits, hydroseeding or mulching immediately after topsoil placement, waste (including concrete
waste) management. The developer will be responsible for the regular maintenance of such construction BMPs.
In addition, the developer will prepare an emergency plan prior to beginning construction work on the sewer line. This
emergency plan shall include special precautions in order to reduce or eliminate the possibility of sewer spill into the
adjacent wetlands. These precautions shall include a readily -identified sequence of emergency measures which are
understood by construction personnel, assurance that necessary tools are available in the event of uncontrolled leakage, a
program and pumps for temporary bypass, if needed, knowledge of critical operating facilities, and a program of defined
roles and responsibilities.

Compliance with the NPDES and SWPPP requirements as demonstrated with the identified BMPs will ensure that the
project will result in a less than significant impact on water quality standards or waste discharge requirements.
b) Substantially deplete groundwater supplies or interfere substantially with ground water recharge such that
there would be a net deficit in aquifer volume or a lowering of the local ground water table level (i.e., the
production rate of pre-existing nearby wells would drop to a level which would not support existing land
uses or planned uses for which permits have been granted)?
No Impact. The sewer pipeline will be entirely impervious and will be installed underground, and will thus have no effect
on groundwater supplies or recharge. The lift station site is generally underlain by fill soil,, alluvium soil and terrace
deposits. The shallow fill material is presumed to have been placed in conjunction with grading operations for the existing
power plant infrastructure. It is anticipated that the groundwater table is relatively shallow in the area and likely to be
encountered at or near sea level.
The lift station site design BMP's will involve a multiple -treatment program, including four different treatment systems
including; (1) a vegetated or river rock Swale located along the southeast side of the project which will treat runoff from the
site through filtering by the vegetation in the channel, filterimg through a subsoil matrix, and filtration into the underlying
soils, (2) an on-line underground wet vault structure which will provide storage for site runoff and improve the settling of
particulate stormwater pollutants, (3) pervious surfaces, which will allow infiltration of oils and other pollutants into the
earth rather than running offsite, and (4) an infiltration basin located at the south end of the site, which will infiltrate
stormwater and will use the natural filtering ability of the soil to remove pollutants from stormwater runoff.
As a result of these design features, no impacts to groundwater or groundwater recharge will occur from the project..
c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the
course of a stream or river, in a manner, which would result in substantial erosion or siltation on- or
off -site?
Less Than Significant Impact. The sewer pipeline will be constructed underground (except at the bridge over the lagoon
channel) and the land surface will in all cases be returned to its original topographic relationships, except along the ridge
north of the Agua Hedionda Lagoon channel, which will be raised approximately 3-feet in height and widened several feet.
Drainage patterns may change temporarily as a result of construction activities; however, each portion of the alignment
would be restored to its approximate original contours (excluding the north end embankment referenced above) following
completion of each particular portion of the pipeline.
The lift station is located within the Carlsbad Hydrologic Unit 904.3 and the Agua Hedionda subarea 904.31. It is to be
constructed on 2.3 acres within and tucked into a low, existing hillside. The hillside presently drains towards the west, to a
low point at the northwest corner of the area, and drains into the lagoon.
Under the post -construction situation, the lift station site will drain in a much more gradual pattern, towards the western
edge of the site. The storm water that leaves the lift station site will then discharge directly into an area in the southwest
corner of the site, and will then drain into the same finger of the lagoon as under the existing condition. More specifically,
a storm drain system, including; (1) a vegetated or river rock swale located along the southeast side of the project, (2) a-n
on-line underground wet vault structure which will provide storage for site runoff and improve the settling of particulate
stormwater pollutants, (3) pervious surfaces which will allow infiltration of oils and other pollutants into the earth, and (4)
an infiltration basin located at the south end of the site, which will infiltrate stormwater and will use the natural filtering
ability of the soil to remove pollutants from stormwater runoff are all proposed to minimize change to the existing drainage
pattern or substantial alteration of the drainage of the lift station area.
Therefore, since no change to the flow patterns over the sewer pipeline will result from the project, and the general flow
pattern from the lift station site would be maintained, and BMPs to control erosion and siltation are being provided as part
of the project, as discussed in Section VIII(a) above, it is determined that less than significant impacts would result from
implementation of the project.

d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the
course of a stream or river, or substantially increase the flow rate or amount (volume) of surface runoff in a
manner, which would result in flooding on- or off -site?
Less Than Significant Impact. As discussed in Section VIII(c) above, the project will result in temporary changes to
drainage along the alignment of the pipeline during construction as the placement of equipment and materials associated
with construction activities, as well as the temporary modification of permeable surfaces, and soil movement along the
alignment would alter existing drainage patterns. Further, the lift station development will result in on -site modification to
the drainage pattern over the 2.3 acres of the lift station. The project will not however, result in a significant alteration of
the existing drainage pattern, and would not substantially increase the flow rate or volume of surface runoff. Thus, a less
than significant impact is assessed.
e) Create or contribute runoff water, which would exceed the capacity of existing or planned storm water
drainage systems or provide substantial additional sources of polluted runoff?
Less Than Significant Impact. The proposed project involves the construction of an underground sewer pipeline, a sewer
lift station and a pipeline support bridge over the Agua Hedionda Lagoon channel. During construction the potential for
additional polluted runoff exists; however compliance with NPDES requirements, including preparation of a SWPP and
implementing the BMPs identified therein would ensure that impacts associated with the creation of runoff water remain
less than significant.
f) Otherwise substantially degrade water quality?
Less Than Significant Impact. The proposed project will connect to existing sewer facilities at both ends of the project,
and there would be no discharges into surface waters during operation of the pipeline.
In order to avoid sewage spills during operation of the lift station, the station design concept incorporates extensive
equipment redundancy for ensuring that equipment failures do not result in wastewater spills. The concept involves a lift
station configuration that includes two independent pumping elements. The lift side of the station includes four 40 hp
pumps. The total lift capacity will maximize the use of the capacity of the existing 42-inch gravity sewer. The force main
side of the station includes four 100 hp pumps. The total pumping, capacity of the station is up to 23.5 mgd on the lift side
and up to 26.5 mgd on the force main side. The station capacity is 50 mgd providing 50% redundancy at peak wet weather
flow conditions (33-mgd) and over 100% redundancy at peak dry weather flows (21 mgd). The force main side and lift side
can independently pump peak dry weather flows (21-mgd). In the event that a total failure occurs on either side, the station
remains operable without consequences under peak dry weather flow conditions.
Multiple redundant features including electrical power to the lift station are also provided, including a split station with two
different means of conveyance to the treatment plant, and emergency back-up power. Emergency power will also be
provided by a built-in onsite diesel fuel generator. The station is designed with alarms to alert officials to the problem and
to enact the contingency plans to reduce flow (upstream lift stations contain storage volume), if necessary.
During project construction, the major temporary staging areas will be located on; (a) the cleared area near the railroad
tracks at the north end of the project; (b) on the YMCA site, (c) immediately east of the proposed lift station site, and (d)
behind the Hilton Gardens Hotel on the City -owned property adjacent to Avenida Encinas. No staging areas will belocated
within any drainages, streams or wetlands. Construction of the project will require grading, excavation and trenching
activities, which could have the potential to allow eroded soils and other pollutants to enter drainage systems. During
construction activities, water will be used for dust control. The use of water will be localized and directed onto stockpiles
of dirt or sand, or into the pipeline trench or the lift station pad excavated area.
The project will require a standard NPDES permit. This NPDES permit will require preparation of a SWPPP to identify
and implement BMPs to reduce impacts to surface water fi-om contaminated storm water discharges. The BMPs to be
implemented by the project are identified in Section V1II(a) above. Compliance with these requirements will ensure that
the project would result in a less than significant impact on water quality.

Also, a number of State of California Coastal Act policies are addressed in the City's adopted LCP, which speak to water
quality/erosion control required of development proposals within the Coastal Zone. Adequacy of the project in relation to
these policies is as follows:
1. Agua Hedionda LCP Coastal Act Policy 30230 Marine Resources. The project complies because the project
avoids impacts to marine resources. The project protects uses of the marine environment in a manner that will
sustain the biological productivity of coastal waters and that will maintain healthy populations of all species of
marine organisms adequate for long-term commercial, recreational, scientific, and educational purposes.
2. Agua Hedionda LCP Coastal Act Policy 30231 Biological Resources. The project complies because it will not
impact biological production and the quality of coastal waters, streams, wetlands, estuaries, and lakes appropriate
to maintain optimum populations of marine organisms and for the protection of human health through, among
other means, minimizing adverse effects of wastewater discharges and entrainment, controlling runoff, preventing
depletion of groundwater supplies and substantial interference with surface water flow, vegetation buffer areas that
protect riparian habitats, and minimizing alteration of natural streams.
3. Agua Hedionda LCP Coastal Act Policy 30240(a) Environmentally Sensitive Habitat Areas. The project complies
because the project avoids impacts with sensitive habitats, with the exception of the important DCSS habitat.
However the CSS in this area is not rare or especially valuable because it is in a series of small, fragmented,
isolated patches, surrounded by a highly urbanized environment. Nor is the impacted vegetation especially
valuable to the ecosystem since the area has already been largely degraded by urbanization, industrialization and
the adjacent railroad. As a result of these factors, the project is not considered ESHA. Notwithstanding that the
project will not impact ESHA, it will mitigate for the 0.05 acres of DCSS that will be impacted through
compliance with the mitigation measures identified in the Mitigation, Monitoring and Reporting Program
(MMRP). Additionally, the only portion of the project that is situated within an identified hardline open space is
the Agua Hedionda channel bridge, which will be situated 17-feet above the surface of the water, and thus will not
impact any hardline- habitat.
4. Agua Hedionda LCP Coastal Act Policy 30240(b) Environmentally Sensitive Habitat Areas. The project complies
because development proposed in areas adjacent: to environmentally sensitive habitat areas and parks and
recreation areas will be sited and designed to prevent impacts which would significantly degrade such areas.
5. Carlsbad LCP Mello H Policy 3-4 Grading and Landscaping Requirements. The project complies because all
graded areas will be improved or landscaped which will minimize erosion. Also grading will not occur during the
rainy season unless sufficient erosion control measures have been included in the project construction program.
6. Carlsbad LCP Mello II Policy 4-3 Accelerated Soil Erosion. The project complies because no portion of the
project is being developed on steep slopes as identified in the LCP. The project also complies because the project
will incorporate BMPs and submit a water quality technical report as specified in the National Pollutant Discharge
Elimination System (NPDES) permit and in the SUSMP. In addition, the proposed project will not result in any
increase in impervious area, the city will include requirements in the coastal development permit approval to allow
inspection and maintenance of the BMPs, the project minimizes land disturbance activities during construction
(e.g., clearing; grading and cut -and -fill). Also, the project proposes to incorporate soil stabilization BMPs on
disturbed areas as soon as feasible. Lift station site design BMPs will include a multiple -treatment program,
including four different treatment systems, i.e.; a vegetated Swale located along the southeast side of the project
which will treat runoff from the site through filtering by the vegetation in the channel, filtering through a subsoil
matrix, and filtration into the underlying soils, an on-line underground wet vault structure which will provide
storage for site runoff and improve the settling of particulate stormwater pollutants, pervious surfaces, which will
allow infiltration of oils and other pollutants into the earth rather than running offsite, and an infiltration basin
located at the south end of the site, which will infiltrate stormwater and will use the natural filtering ability of the
soil to remove pollutants from stormwater runoff.
7. Carlsbad LCP Mello II Policy 4-4 Removal of Natural Vegetation. The project complies and will not significantly
contribute to the removal of vegetation because it will minimize the sensitive vegetation impacted and will
mitigate for that removed.
8. Carlsbad LCP Mello H Policy 4-5 Soil Erosion Control Practices. The project complies because onsite erosion
will be avoided as a result of the use of silt fences, sandbags and straw mulch rolls being placed around excavated
trench spoils during the construction period. Also, all storm drains and natural drainages situated downstream
from the construction will be protected by linear sediment barriers or similar erosion control devices.
9. Carlsbad LCP Mello II Policy 4-6 Sediment Control Practices. The project complies sediment control will be
provided through the use of silt fences, sandbags and straw mulch rolls being placed around excavated trench

spoils during the construction period. Also, all storm drains and natural drainages situated downstream from the
construction will be protected by linear sediment barriers or similar erosion control devices.
10. Zoning Ordinance Chapter 21.203.040(B)(4) Drainage, Erosion, Sedimentation, Habitat. The project complies
because the project incorporates erosion control measures to minimize urban pollutants, erosion and sedimentation
in accordance with: (1) the requirements of the city's grading ordinance, storm water ordinance, standard urban
storm water mitigation plan (SUSMP) dated April 2',003 and as amended, and the master drainage plan dated 1994,
as those documents are certified as part of the city's LCP; (2) the city's jurisdictional urban runoff management
program (JURMP) and the San Diego County Hydrology Manual to the extent that these requirements are not
inconsistent with any policies of the LCP; and (3) the additional requirements contained herein. Such mitigation
shall become an element of the project and shall be installed prior to the initial grading.
In addition, the project will incorporate BMPs and submit a water quality technical report as specified in the National
Pollutant Discharge Elimination System (NPDES) permit and in the SUSMP. In addition, the proposed project will not
result in any significant increase in impervious area. Pervious surfaces will be utilized as an infiltration BMP on the lift
station site. These pervious surfaces will capture, retain and infiltrate a high level of runoff into the ground. Also, the
existing lift station and its concrete overflow basin will be demolished and removed. The overflow basin will subsequently
be filled with soil and vegetated.. Further, the project minimizes land disturbance activities during construction (e.g.,
clearing, grading and cut -and -fill) and the project proposes to incorporate soil stabilization BMPs on disturbed areas as
soon as feasible. Thus, a less than significant impact is assessed.
g) Place housing within a 100-year flood hazard area as mapped on a Federal Flood Hazard Boundary or
Flood Insurance Rate Map or other flood delineation map?
No Impact. The Federal Emergency Management Agency (FEMA) indicate that the only portion of the project alignment
that would impact the 100-year flood hazard zone area would be the Agua Hedionda channel bridge span to be constructed
at a level approximately 20-feet above the surface of the flood zone, to carry the sewer pipeline across the channel. The
bridge support abutments will be set at 10-foot elevation. Because the project will be constructed a minimum 10-feet above
the 100-year flood zone, the project will not impact any 100-year flood capacity area. No manholes for the pipeline are to
be located within the 100-year flood zone. Therefore, it is determined that the project does not encroach or impact a
Federal Flood Hazard Boundary or Flood Insurance Rate map or other flood delineation, and no impact will result. Please
see Figure 13, FEMA Map of the area around and near the proposed lift station.
h) Place within 100-year flood hazard area structures, which would impede or redirect flood flows?
No Impact. The project does not propose any structures within the 100-year flood hazard area. Further, the project will
remove the existing trestle bridge structure which supports the existing 42-inch sewer pipe. Optionally, the structure
supporting the 12-inch high pressure natural gas transmission line may be removed. The sewer line bridge structure
contains eight (8) narrow bridge support/pilings which presently sequence across and into the bottom of the Agua Hedionda
Lagoon channel. These support/pilings are'14-inches in diameter, and set approximately 20-feet below the mud line on the
bottom of the lagoon, and create some measurable amount of water friction through the channel, which will be eliminated
through implementation of the project. Once removed, the in -channel piling holes will partially collapse and then fill with
sand and sediment from the tidal action. As an option, the existing natural gas transmission line bridge may also be
removed. This bridge contains four driven wood piles (two on land and two in the channel). The natural gas bridge would
be removed in the same fashion as the existing sewer trestle bridge. As a result of these factors, it is determined that no
impacts (and potentially a minute beneficial impact) to the 100-year flood hazard area would occur from implementation of
the project.
i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including
flooding as a result of the failure of a levee or darn?
No Impact. The project alignment is not located within the inundation zone for any dams upstream of the project. Further,
the project does not propose the placement of any permanent structures that would be occupied by residents, employees or
patrons. As explained herein and in Sections VIII(g) and (h), the proposed project would not result in increased exposure
of people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the
failure of a levee or dam. As a result, no impacts would occur.

Agua Hedionda Sewer Line and Lift Station Project
PDP OU-42(C) I SP 144(L) /RP 10-261 CDP 10-1 71HDP 10-051 SUP 10-021 Hd1P 10-03
j) Inundation by seiche, tsunami, or mudflow?
Less Than Significant Impact. The project alignment is not situated near or immediately adjacent to an embanked water
body such as a reservoir, dam or aboveground storage tank; however the pipeline does cross above the Agua Hedionda
Lagoon, which is a coastal body of shallow water formed where sand and low-lying landform presents a partial barrier to
the open sea. The proposed lift station however, will be located at a finished floor elevation of approximately 32-feet above
mean sea level (MSL). It would be highly unusual (and regionally destructive) for a seiche (a wave or oscillation of the
surface of water in an enclosed or semi -enclosed basin that continues from a few minutes to a few hours as a result of
seismic or atmospheric disturbances) or tsunami to create a wave to reach that elevation. No significant potential for
mudflow on the project site or alignment could result. Therefore, the project has a less than significant potential impact due
to seiche or tsunami.
k) Increased erosion (sediment) into receiving surface waters.
Less Than Significant Impact. Upon completion of construction, the proposed project will not result in any permanent
features that will increase erosion or the transportation of sediment into receiving surface waters.
During construction soil will be cleared and unearthed which could result in erosion. In order to avoid erosion and
transportation of downstream sediment from the project while construction is taking place, as indicated in Section VII(a),
the project construction BMPs to be used shall include, but are not limited to; silt fencing, fiber rolls or gravel bag berms,
street sweeping and vacuuming, covering soil piles, storm drain inlet protection, stabilized construction entrances and exits,
hydroseeding or mulching immediately after topsoil placement, waste (including concrete waste) management. Also, all
storm drains and natural drainages situated downstream from the construction will be protected by linear sediment barriers
or similar erosion control devices. Weather monitoring will take place in order to avoid exposed soils during times of
heavy rainfall. The streets within and around the construction site will be swept and maintained regularly during the
construction period.
In addition, compliance with the NPDES and SWPPP requirements as demonstrated with the BMPs identified will ensure
that the project will result in a less than significant impact on erosion potential into receiving surface waters of the project.
1) Increased pollutant discharges (e.g., heavy metals, pathogens, petroleum derivatives, synthetic organics,
nutrients, oxygen -demanding substances and trash) into receiving surface waters or other alteration of
receiving surface water quality (e.g., temperature, dissolved oxygen or turbidity)?
Less Than Significant Impact. The proposed project includes installation of an underground sewer pipeline. The pipeline
will be constructed of impervious material and thus will not be subject to release of pollutants from the interior of the pipe
to the exterior soil environment.
The lift station design concept incorporates extensive equipment redundancy for ensuring that equipment failures do not
result in wastewater spills. The concept involves a lift station configuration that includes two independent pumping
elements. The lift side of the station includes four 5-mgd pumps. The total lift capacity will maximize the use of the
capacity of the downstream existing 42-inch gravity sewer. The lift side of the station includes four 40 hp pumps. The
force main side of the station includes four 100 hp pumps. The total pumping capacity of the station is up to 23.5 mgd on
the lift side and up to 26.5 mad on the force main side. The station capacity is 50 mgd providing 50% redundancy at peak
wet weather flow conditions (33-mgd) and over 100% redundancy at peak dry weather flows (21 mgd). In the event that a
total failure occurs on either side, the station remains operable without consequences under peak dry weather flow
conditions and contains power redundancy and significant upstream storage capacity under catastrophic circumstances were
they to occur under peak wet weather conditions.
The station is also with two independent'electrical circuits, and will include an automatic standby transfer switch in the
event of catastrophic power failure. In the event of full regional blackout, emergency power will be provided by an onsite
generator. Under such circumstances, the station is designed with alarms to alert officials to the problem and to enact the
contingency plans to reduce flow (upstream lift stations contain storage volume) under such circumstances, if necessary.
The upstream pipe also contains a significant amount of storage capacity.

As previously mentioned, during construction, all graded areas will be improved or landscaped which will minimize
erosion. Also, grading will not occur during the rainy season unless sufficient erosion control measures have been included
in the project construction program. The project will use silt fences, sandbags and straw mulch rolls around excavated
trench spoils during the construction period. Also, all storm drains and natural drainages situated downstream from the
construction will be protected by linear sediment barriers or similar erosion control devices. Thus, the project incorporates
erosion control measures to minimize urban pollutants, erosion and sedimentation during construction as well as after the
project has been completed.
The project construction will also be required to comply with NPDES requirements of the City of Carlsbad. As a result,
any construction impacts to water quality into receiving waters, including the Agua Hedionda Lagoon, will be less than
significant.
m) Changes to receiving water quality (marine, fresh. or wetland waters) during or following construction?
Less Than Significant Impact. The northern portion of the project aligmment lies adjacent to, andcrosses above Agua
Hedionda Lagoon. Once the new sewer line project is complete, the project also involves the removal of the existing trestle
bridge which supports the existing sewer line. Optionally the structure supporting the high pressure natural gas
transmission line may be removed. Removal of these existing bridges and their associated numerous narrow bridge
support/pilings would have a potentially minor beneficial effect on water transport through the lagoon channel. Thus, it is
determined that the fully -constructed project will not result in any significant change (and potentially a minute beneficial
effect) on Agua Hedionda Lagoon or any other receiving waters.
During construction, all graded areas will implement water quality BMPs in order to minimize and eliminate the potential
for changes to receiving downstream waters. For example, grading will not occur during the rainy season unless sufficient
erosion control measures have been included in the project construction program. The project will utilize silt fences,
sandbags and straw mulch rolls around excavated trench spoils during the construction period. Also, all storm drains and
natural drainages situated downstream from the construction will be protected by linear sediment barriers or similar erosion
control devices. Thus, . the project incorporates erosion control measures to minimize urban pollutants, erosion and
sedimentation during construction as well as after the project has been completed.
As a result of these factors, any changes to receiving water quality during construction would be less than significant.
n) Increase in any pollutant to an already impaired water body as listed on the Clean Water Act Section 303(d)
list?
Less Than Significant Impact. Agua Hedionda Lagoon is listed on the Clean Water Act Section 303(d) list for impaired
water bodies for indicator bacteria and sedimentation/siltation. As previously indicated in the discussion regarding Sections
VII(a), (f) and (1), the project will result in a less than significant impact on the water quality of Agua Hedionda Lagoon.
o) Increase impervious surfaces and associated runoff?
Less Than Significant Impact. As discussed in Section VII(c) above, the project will result in temporary changes to
drainage along the alignment of the pipeline during construction as the placement of equipment and materials associated
with construction activities, as well as the temporary modification. of permeable surfaces and soil movement along the
alignment would alter existing runoff patterns. Further, the lift station development will result in on -site modification to the
runoff over the 2.3 acres of the lift station. However, on the lift station site, pervious surfaces will be utilized as a site
design infiltration BMP. This BMP will capture, retain, and infiltrate a minimum of 80% of runoff into the ground.
Therefore minimal runoff associated with the construction of new impervious surfaces at the lift station site would result
from the project, and a less than significant impact is assessed.
p) Impact aquatic, wetland, or riparian habitat?
Less Than Significant Impact. As indicated in the Section IV(b), the proposed project will not directly impact
(temporarily or permanently) any wetland or riparian habitats. The project does, however, bridge the Agua Hedionda
Lagoon channel. The Agua Hedionda Lagoon channel is an open water habitat subject to state and federal wetland
jurisdiction.

US Army Corps of Engineers policies dictate that, on coastal bays, jurisdictional wetlands extend to an elevation of 1.5 feet
above the mean ordinary high tide level, regardless of the presence or absence of other wetland indicators. The RWQCB,
CDFG and the CCC also operate using this definition of wetlands along tidal margins. A review of tide charts for the
Carlsbad area indicates that the mean high tide level is 4.6 feet above mean sea level (MSL). Therefore the wetland
boundary follows the 6.1 foot above MSL elevation on Agua Hedionda Lagoon in this location. The bottom of the channel
under the bridge location is rocky (riprap) and sandy, with no observable indication of eelgrass or other sensitive
submerged aquatic vegetation. Thus, the shadow of the bridge will not impact any sensitive wetland habitat.
The proposed bridge vertical support footings will be constructed on upland terrain, set at the approximate 10-foot elevation
and the horizontal pipe support will fully span the entire length of the channel (the horizontal span will be at approximately
20-foot elevation) from the north side 10-foot elevation support to the south -side 10-foot elevation support. Thus, the
project does not encroach or impact on jurisdictional wetlands in this area. Section 10 of the River and Harbors Act
however, requires authorization fiom the U.S. Army Corps of Engineers for the construction of any structure in or over any
navigable water of the United States. Thus, the proposed channel bridge and removal of the existing trestle bridges will
require issuance of a NWP 12 (Utility Line Activities) pursuant to this Act prior to removal of the trestle bridges, or
construction of the new bridge. Likewise, water quality certification issued by the San Diego Regional Water Quality
Control Board pursuant to Section 401 of the Clean Water .Act, and a state Notification of Lake or Streambed Alteration
Agreement pursuant to Section 1602 of the California Fish and Game Code will be required for the same reasons.
Also, the riparian scrub habitat occurring near the south end of the project is supported by storm drain outfall passing
beneath Avenida Encinas, and would be expected to be considered jurisdictional pursuant to state and federal guidelines.
However, a wetland delineation was not performed for this drainage because the project will not result in any impacts to
any of the vegetation in this drainage area. Project work near this riparian scrub habitat will occur only on the existing road
surface of Avenida Encinas. Also, the project will utilize measures to ensure that soil and construction debris avoids
entering this drainage during or after the construction process.
It is concluded that a less than significant impact to wetlands or riparian habitat will result from implementation of the
project.
As a result, the project will result in less than significant impacts to aquatic, wetland or riparian habitats.
q) The exceedance of applicable surface or groundwater receiving water quality objectives or degradation of
beneficial uses?
Less Than Significant Impact. As indicated in Sections VIII(a) and VIII(1), the project will not exceed the applicable
surface or groundwater receiving water quality objectives and will not degrade beneficial uses of the Agua Hedionda
Lagoon and other receiving water bodies. Thus, impacts would be considered less than significant.

a) Physically divide an established community?
No Impact. The proposed project involves the construction of an underground sewer trunk pipeline, a pipeline bridge
structure and a sewer lift station, and also involves the demolition of the existing obsolete lift station, the removal of the
existing trestle bridge structures, and the removal and filling, of the existing concrete overflow basin. The project is situated
within the urbanized area of the city of Carlsbad; however some of the directly -adjacent land uses are open space. The
majority of the uses are power plant or industrial oriented, commercial or business park, or transportation, as indicated on
the following table.

and landscaping.
The proposed project will result in no permanent aboveground structures, except the previously -mentioned lift station and
bridge structure (and manhole lids — which will be visible only from passersby in close proximity). As a result, no impact
would occur that would disrupt or divide the physical arrangement of the established community.
b) Conflict with -any applicable land use plan, policy, or regulation of an agency with jurisdiction over the
project (including but not limited to the general plan, specific plan, local coastal program, or zoning
ordinance) adopted for the purpose of avoiding or mitigating an environmental effect?
No Impact. The General Plan and zoning of the property allows for the proposed land uses. The entire property is within
the coastal zone and the northern portion of the project alignment is within the boundaries of Specific Plan-144. Project
compliance with each relevant land use document is examined below:
General Plan. The project travels through property with several different General Plan Land Use designations.
These designations are; TC (Transportation Corridor), U (Public Utilities), T-R (Travel -Recreation Commercial,
and Secondary Arterial Roadway. All of these designations contain policies which allow public infrastructure as a
permitted use and the use would not conflict with these designations. The land use designations will not be
changed through implementation of the project. The Land Use Element further requires that public facilities be
provided in the city adequate for the projected population. The project complies with these provisions by providing
the allowed sewer lines consistent with General Plan policies.
2. Zoning Ordinance. The subject project travels through property that has several different City zones. These
zones are; T-C (Transportation Corridor), O-S (Open Space), P-U (Public Utility), C-T-Q (Commercial Tourist —
Qualified Overlay), C-1 (Neighborhood Commercial) and Arterial Roadway. All of these zones allow public
infrastructure improvements as a permitted use. Therefore the project will not conflict with the Zoning Ordinance
or unduly preclude the future use of parcels consistent with the Zoning guidelines.
3. Coastal Act Compliance. The project is located within the California Coastal Zone, specifically within the Agua
Hedionda and the Mello II segments of the adopted Local Coastal Program (LCP). The portion of the project
north of Cannon Road is in the Agua Hedionda segment, and south of Cannon Road is in the Mello II segment.
While the Agua Hedionda Land Use Plan has been adopted by the City of Carlsbad, no Implementation Plan has
been certified by the California Coastal Commission to date, and thus the Coastal Commission retains coastal

permit authority for improvements within this segment. The Agua Hedionda land uses are generally consistent
with the Carlsbad General Plan land uses for the project alignment within the Agua Hedionda LCP segment. The
Mello II Land Use Plan designates the entire alignment length south of Cannon Road as Secondary Arterial
Roadway. Public infrastructure projects are allowed in all of these respective land use designations. The proposed
project is consistent with this policy.
Also, a number of adopted City LCP policies address water quality/erosion control required of project's within the
Coastal Zone. Compliance of the project in relation to these policies is as follows:
a. Agua Hedionda LCP Policy 5.1 Public Works. The project complies because this policy dictates that all
new utility systems shall be placed underground as feasible and commonly practiced, and the project is
almost totally and underground project, as commonly practiced.
b. Agua Hedionda LCP Coastal Act Policy .30230 Marine Resources. The project complies because the
project avoids impacts with marine resources. The project protects uses of the marine environment in a
manner that will sustain the biological productivity of coastal waters and that will maintain healthy
populations of all species of marine organisms adequate for long-term commercial, recreational,
scientific, and educational purposes
c. Agua Hedionda LCP Coastal Act Policy 30231 Biological Resources. The project complies because it
will not impact biological production and the quality of coastal waters, streams, wetlands, estuaries, and
lakes appropriate to maintain optimum populations of marine organisms and for the protection of human
health through, among other means, minimizing adverse effects of wastewater discharges and
entrainment, controlling runoff, preventing depletion of groundwater supplies and substantial interference
with surface water flow, vegetation buffer areas that protect riparian habitats, and minimizing alteration
of natural streams.
d. Agua Hedionda LCP Coastal Act Policy 30240(a) Environmentally Sensitive Habitat Areas. The project
complies because environmentally sensitive habitat areas (ESHA) will be avoided to the degree feasible
and the small edge -areas of DCSS impacted are not considered ESHA because they are not rare or
especially valuable because they are situated in a series of small, fragmented, isolated patches,
surrounded by a highly urbanized, industrialized environment. Further, the DCSS impacts will be fully
mitigated with in -kind creation, and will thus be protected against any significant disruption -of habitat
values.
e. Agua Hedionda LCP Coastal Act Policy 30240(b) Environmentally"Sensitive Habitat Areas. The project
complies because development proposed in areas adjacent to environmentally sensitive habitat areas and
parks and recreation areas will be sited and designed to prevent impacts which would significantly
degrade such areas.
f. Carlsbad LCP Mello H Policy 3-4 Grading and Landscaping Requirements. The project complies
because all graded areas will be improved or landscaped which will minimize erosion. Also grading will
not occur during the rainy season unless sufficient erosion control measures have been included in the
project construction program.
g. Carlsbad LCP Mello H Policy 4-3 Accelerated Soil Erosion. The project complies because no portion of
the project is being developed on steep slopes as identified in the LCP. The project also complies
because the project will incorporate BMPs and submit a water quality technical report as specified in the
National Pollutant Discharge Elimination System (NPDES) permit and in the SUSMP. In addition, the
proposed project will not result in any increase in impervious area, the city will include requirements in
the coastal development. permit approval to allow inspection and maintenance of the BMPs, the project
minimizes land disturbance activities during construction (e.g., clearing, grading and cut -and -fill). Also,
the project description proposes to incorporate soil stabilization BMPs on disturbed areas as soon as
feasible. Lift station site design BMPs will include a multiple -treatment program, including four different
treatment systems.; (1) a vegetated or river rock Swale located along the southeast side of the project
which will treat runoff from the site through filtering by the vegetation in the channel, .filtering through a
subsoil matrix, and filtration into the underlying soils, (2) an on-line underground wet vault structure
which will provide storage for site runoff and improve the settling of particulate stormwater pollutants,
(3) pervious surfaces; which will allow infiltration of oils and other pollutants into the earth rather than
running offsite, and (4) an infiltration basin located at the south end of the site, which will infiltrate
stormwater and will use the natural filtering ability of the soil to remove pollutants from stormwater
runoff.

h. Carlsbad LCP Mello H Policy 4-4 Removal of Natural vegetation. The project complies and will not
significantly contribute the removal of vegetation because it will minimize the sensitive vegetation
impacted and will mitigate for that removed.
i. Carlsbad LCP Mello H Policy 4-5 Soil Erosion Control Practices. The project complies because onsite
erosion will be avoided as a result of the use of silt fences, sandbags and straw mulch rolls being placed
around excavated trench spoils during the construction period. Also, all storm drains and natural
drainages situated downstream from the construction will be protected by linear sediment barriers or
similar erosion control devices.
j. Carlsbad LCP Mello II Policy 4-6 Sediment Control Practices. The project complies sediment control
will be provided through the use of silt fences, sandbags and straw mulch rolls being placed around
excavated trench spoils during the construction period. Also, all storm drains and natural drainages
situated downstream from the construction will be protected by linear sediment barriers or similar erosion
control devices.
Zoning Ordinance Chapter 21.203.040(B)(4). The project complies because the project incorporates erosion
control measures to minimize urban pollutants, erosion and sedimentation in accordance with: (1) the requirements
of the city's grading ordinance, storm water ordinance, standard urban storm water mitigation plan (SUSMP) dated
April 2003 and as amended, and the master drainage plan dated 1994, as those documents are certified as part of
the city's LCP; (2) the city's jurisdictional urban runoff management program (JURMP) and the San Diego
County Hydrology Manual to the extent that these requirements are not inconsistent with any policies of the LCP;
and (3) the additional requirements contained herein. Such mitigation shall become an element of the project and
shall be installed prior to the initial grading.
Carlsbad Habitat Management Plan (HMP). Both the LCP Land Use Plans and the HMP have strict policies to
discourage destruction of sensitive habitat, including no net loss of sensitive habitats and significant restrictions on
disturbing wetlands. The project is situated in an urbanized area and will mitigate for impacts to sensitive habitat
as indicated in Section IV of this environmental analysis. The project proposes no disturbances to wetlands.
Further, as discussed in Section VIII, the project will not result in additional urban runoff, pollutants, erosion or
sedimentation as no grading is proposed and no new uses will be constructed.
Specific Plan 144(J). In 1998, the City Council adopted a Resolution of Intention (ROI Reso. No. 98-1.45),
directing city staff to study and consider a comprehensive land use plan for properties within Specific Plan 144
(SP-144), an area of approximately 650-acres encompassing the Encina Power Plant, Agua Hedionda Lagoon, and
adjacent lands. The northern one-third of the project is situated within the SP-144 area. The purpose of this ROI
was to resolve the many land use issues associated with the properties within the SP-144 area, including
reconciliation of inconsistent zoning and land use designations, resolution of outstanding LCP issues regarding
open space and access, and revision of out -dated plans that did not accurately show existing structures and
improvements. The study was not done, but subsequent actions of the City Council reconfirmed that a
comprehensive specific plan update is necessary, and that it should be applicant, rather than city -initiated.
While the proposed Agua Hedionda Sewer Line and Lift Station project is an improvement partially within SP-
144, it is not subject to the comprehensive update requirement because it does not trigger or significantly impact
the land use, public access and other issues of concern identified in the 1998 NOI. Specifically, the project is not
subject to the comprehensive update requirement for the following reasons:
a. The project improves major regional infi-astructure that cannot be feasibly relocated. The project will
replace existing facilities which have reached the end of their useful life.
b. The lift station and sewer line are not significant new land uses; they would improve existing like
facilities and would be constructed in generally the same locations as those existing facilities. They
would be located in an existing utility corridor bordered on the west side by the railroad. The majority of
the pipeline portion of the project within SP-144 would be undergrounded. Furthermore, care has been
exercised in the design of above -ground structures such as the proposed lift station that features a low
profile and partially buried structure and the replacement bridge for the sewer line.

c. As a replacement and expansion of existing, like utility uses in generally the same location, the project
would not represent a new, significant impediment to addressing the issues identified in the ROI,
including land use and public access.
d. The project proposes no changes to general plan land use or zoning designations or any conditions or
policies of SP-144.
e. As discussed in this section, the project complies with all applicable land use documents affecting the
SP-144 area, including the General Plan, Zoning Ordinance, Precise Development Plan, South Carlsbad.
Coastal Redevelopment Area Plan, Agua Hedionda Land Use Plan, and Scenic Corridor Guidelines.
f. The project would result in only minor changes to SP-144(J) and PDP 00-02(B) in the form of text and
graphic changes that merely recognize the proposed improvements. Consistent with the most recently
adopted version of the specific plan, SP 144(J), and PDP 00-02(B), these minor changes are considered
"formal amendments" to the documents.
Since the project would not require a comprehensive update, it instead proposes an amendment to SP-144. The
amendment enables the project to continue to be a part of SP-144 and subject to any future comprehensive review.
An amendment is also required by SP- 144(J), which specifically requires such for any formal amendment to PDP
00-02(B), further discussed below.
7. Precise Development Plan 00-02(B). The project will require a formal amendment to the Precise Development
Plan (PDP) 00-02(B) pursuant to Section VI of that document. Formal amendments are required for all but
generally minor improvements. This PDP covers approximately all 95 acres of the Encina Power .Station,
extending from Carlsbad Boulevard to Interstate-5 along the south shore of Agua Hedionda Lagoon. The PDP is
the primary approval process for the public utility uses within this primarily electrical -generating area.
Developments within the Public Utility Zone necessitate approval of a PDP. Since the proposed use replaces an
allowed use in the PDP, the amendment will consist of text and graphic changes to update the PDP to reflect the
proposed improvements. It is not anticipated that the project would trigger revisions to PDP standards.
8. South Carlsbad Coastal Redevelopment Plan. The portion of the project located within the Public Utility Zone is
located within the South Carlsbad Coastal Redevelopment area, and thus this portion of the project will require a
redevelopment permit from the City of Carlsbad Housing and Redevelopment Commission.
9. Airport Land Use Compatibility Plan (ALUCP). The project has been reviewed by the San Diego County
Regional Airport Authority and the City of Carlsbad has received correspondence that no further Airport Land Use
Commission review is necessary, per the requirements of the McClellan -Palomar Airport Land Use Compatibility
Plan (ALUCP) Carlsbad, CA, March 4, 2010. Thus the project is considered consistent with the Airport Land Use
Compatibility Plan.
As a result of these factors, it is determined that the proposed project will not conflict with any applicable land use plan,
policy, or regulation of an agency with jurisdiction over the ,project, as indicated, and no impact is assessed.
c) Conflict with any applicable habitat conservation plan or natural community conservation plan?
Potentially Significant Unless Mitigation Incorporated. The City of Carlsbad Habitat Management Plan (HMP)
designates a natural preserve system and provides a regulatory framework for determining impacts to sensitive biological
resources and assigning mitigation for any impacts that do occur. In addition, the project is also located within the
California Coastal Zone and the Mello II and Agua Hedionda segments of the adopted Local Coastal Program (LCP). No
other local, regional or state habitat conservation plans specific to this site encumber the property.
The project crosses HMP Core 44, which is identified as a core area for wildlife protection and connectivity pursuant to the
HMP. The project however, will mitigate for impacts to vegetation communities protected by that HMP, as discussed in IV
(a) above.
The HMP contains a number of Adjacency Standards that specifically apply to projects adjacent to sensitive habitat. As
this project is located in the Mello 11 Land Use and Implementation Plan segment of the City's Local Coastal Program, it is

subject to these policies. However, since the project does not permanently disturb any sensitive habitat, the majority of
these policies do not apply.
1. Fire Management. The project is proposing only two above -grade structures, the sewer lift station and the Agua
Hedionda Lagoon channel bridge structure. As a result of the specific characteristics of these structures, neither of
these structures will necessitate a fire suppression or "clear area" around them. As a result the project does not
result in impacts that would affect Fire Management.
2. Erosion Control. The project construction activities will include appropriate temporary erosion and sediment
control protections so that all exposed soil in the area of the construction will be protected from erosion. This will
include silt fences, sandbags and straw mulch rolls being placed around excavated trench spoils during the
construction period. Also, all storm drains and natural drainages situated downstream from the construction will
be protected by linear sediment barriers or similar erosion control devices. Weather monitoring will take place in
order to avoid exposed soils during times of heavy rainfall. The streets within and around the construction site
will be swept and maintained regularly during the construction period. The project will provide a multiple -
treatment erosion control program, including a vegetated Swale located along the southeast side of the project
-which will treat runoff from the site through filtering by the vegetation in the channel, filtering through a subsoil
matrix, and filtration into the underlying soils; an on-line underground wet vault structure which will provide
storage for site runoff and improve the settling of particulate stormwater pollutants; pervious surfaces, which will
allow infiltration of oils and other pollutants into the earth rather than running offsite; and an infiltration basin
located at the south end of the site, which will infiltrate stormwater and will use the natural filtering ability of the
soil to remove pollutants from stormwater runoff. The project will not direct any new surface drainage directly
into Agua Hedionda Lagoon.
3. Landscaping Restrictions. The proposed project will impact approximately 0.05 acres of Diegan coastal sage
scrub (sensitive biological habitat). It will also involve grading of areas in proximity to sensitive habitat. This
grading will be landscaped with native, non-invasive species for erosion control purposes. Upon completion of the
pipe installation, all open -trenched areas will be re -vegetated to the state the area was in prior to construction.
4. Fencing, Signs, and Lighting. Fences, signs, and lighting can assist in the protection and understanding of
biological resources. However, they can also negatively impact wildlife and plants by inviting vandalism,
restricting wildlife movement, and upsetting nocturnal species. The project complies with this adjacency standard
because only low intensity security lighting will be provided on the lift. station. Permanent fencing is only
proposed around the lift station for security purposes. No pennanent fencing is proposed for the balance of the
proj ect.
5. Predator and Exotic Species Control. The project would comply with this standard in the following ways: (1) the
project will mitigate for permanent impacts to biological resources, and thus will not affect the movement of any
native resident or migratory wildlife species, or wildlife corridors, and (2) temporary impacts will be minimized
through coordinated placement of excavated soil and storage of machinery and materials as indicated in Section
IV(a),
The HMP also includes Additional Conservation Standards to be applied to properties in the Coastal Zone (Policies 7-1
through 7-14). The following is an analysis of compliance with these Conservation Standards:
Policy 7-1. The project complies because it does not encroach into or propose construction in an environmentally
sensitive habitat area (ESHA). ESHA is defined in the Coastal Act Sect. 30107.5 as; "Any area in which plant or
animal life or their habitats are either rare or especially valuable because of their special nature or role in an
ecosystem and which could be easily disturbed or degraded by human activities and developments. The project
avoids impacts to sensitive habitats, with the exception of minor slivers of DCSS. The DCSS is surrounded by a
highly urbanized environment, and thus are not rare, nor are they especially valuable to the ecosystem which has
already been largely degraded by urbanization, industrialization and the adjacent railroad. As a result of these
factors, the project does not impact ESHA. Notwithstanding that the project will not impact ESHA, it will
mitigate for the 0.09 acres of sensitive biological habitats that will be impacted through compliance with the
mitigation measures identified in the Mitigation, Monitoring and Reporting Program (MMRP). Additionally, the
only portion of the project that is within a hardline open space is the Agua Hedionda channel bridge, which is
situated 17-feet above the surface of the water, and thus will not impact any hardline habitat.

2. Policy 7-2. The project complies because it mitigates for impacts to DCSS through 0.05 acres of credit debiting
from the Lake Calavera Mitigation Parcel, and also provides an additional 0.09 acre of revegetation (creation) of
DCSS on or near the impact location. This 0.09 acre; of DCSS revegetation is expected to occur within and around
the eastern half of the demolished, filled -in. existing lift station overflow basin, but could occur in a different
location in the area. Thus, as a result of the inclusion of Mitigation Measures BIO-1 and BIO-2, the project will
result in no -net -loss of DCSS.
3. Policy 7-3. The project complies because it does not: impact any Oak Woodland vegetation.
4. Policy 7-4. The project complies because it does not: impact any streamcourse.
5. Policy 7-5. The project complies because it does not: impact any ephemeral drainage or ephemeral stream.
6. Policy 7-6. The project complies because it does not: impact any delineated wetlands.
7. Policy 7-7. The project complies because the only impact to wetlands from the project is the removal of the trestle
bridge(s) and trestle footings and their replacement with the new bridge (which will span_ over the top of the
wetlands). Thus, the temporary construction impacts to wetlands are not permanent and the project will result in
-no loss of wetland.
8. Policy 7-8. The project complies because the impacts to DCSS are incidental and will be fully mitigated and no
impacts are proposed to Maritime Succulent Scrub, Southern Maritime Chaparral, Southern Mixed Chaparral,
Native Grassland or Oak Woodland, and therefore no mitigation is required for these vegetation types.
9. Policy 7-9. The project complies because it does not impact CSS, Southern Maritime Chaparral, Maritime
Succulent Shrub, Native Grassland or Oak Woodland, and therefore no mitigation is required for these vegetation
types.
10. Policy 7-10. This policy is not applicable because the project is not highly constrained (i.e.; is less than 80%
constrained), and thus the project is in compliance with this policy.
11. Policy 7-11. The project complies because all proposed structures (except for the proposed bridge across the Agua
Hedionda Lagoon channel) will maintain in excess of the minimum 100-foot wetland setback, and in excess of the
minimum 20-foot setback from all DCSS. The bridge structure however, is location dependent because no
feasible alternative location exists for the bridge, and by -definition, it must cross the channel. Further, the bridge
will replace an existing bridge which will be removed. Thus, a reduction in setback for the bridge will be
necessary. With this anticipated reduction in setback for the location -dependent bridge, the project is in
compliance with this policy.
12. Policy 7-12. The project complies because all graded areas will be improved or landscaped which will minimize
erosion. Also grading will not occur during the rainy season unless sufficient erosion control measures have been
included in the project construction program.
13. Policy 7-13. This policy is not applicable to the project because the project is not located on lands adjacent to
Macario Canyon and Veterans Memorial Park.
14. Policy 7-14. This policy is not applicable because the project is not located on any of the properties identified.
The project would minimize and mitigate for impacts to sensitive vegetation and would not affect the functioning of the
hardline open space area including the Agua Hedionda Lagoon and thus is considered consistent with the City of Carlsbad
Habitat Management Plan for Natural Communities in the City of Carlsbad. Therefore, with the implementation of the
proposed mitigation measures, as stated in Section IV — Biological Resources, above, any potential impacts would be less
than significant.

a) Result in the loss of availability of a known mineral resource that would be of future value to the region and
"the residents of the State?
No Impact. No known or expected mineral deposits of future value to the region and the residents of the state are located
in the immediate vicinity of the subject project. The Geotechnical Revaluation Agua Hedionda Lift Station and Force
Main, Carlsbad. California, dated August 3, 2009, by Ninyo & Moore, concludes that the project alignment is generally
underlain by fill, alluvium, old paralic deposits, materials of the Santiago Formation and terrace deposits. Fill soil is
presumed to have been placed in the area in conjunction with grading for the adjacent land uses, including the railway,
building pads associated with the power plant, commercial structures, and roadways. The fills are generally expected to be
relatively shallow; however fills placed to construct the railroad where the proposed pipe bridge across the Agua Hedionda
Lagoon channel is proposed may be up to 35 feet deep. These fill soils would be expected to have a low potential for
mineral resources.
Alluvial deposits also underlay the area around the Agua Hedionda Lagoon. The materials generally consisted of light olive
gray to dark brown, poorly consolidated, sands and silty sands. In Iocations where the pipe bridge is proposed to cross
Agua Hedionda Lagoon, at the north and south abutment locations, the alluvium is anticipated to extend to depths of about
150 feet and 75 feet deep, respectively. These alluvial soils would be expected to have a low potential for mineral
resources.
Pleistocene -age terrace deposits were observed along the west side of Avenida Encinas, south of Palomar Airport Road and
along the railroad right of way south of Cannon Road. The materials observed generally consist of light brown to reddish -
brown, damp, loose to dense, silty, and fine to medium -grained sand. The terrace deposits are expected to underlie the
surficial soils across the project site. In previous excavation in the area, these Pleistocene -age deposits are not known to
have a significant potential for mineral resources.
Further, the project alignment does not cross any area of mineral resources as identified in the City of Carlsbad's General
Plan Update MEIR 93-01, dated March 1994, map 5.13-1. As a result of the minor amount of trenching excavation and
disruption of the surface of the land that will result from the proposed project, no impact to the potential for valuable
mineral deposits is anticipated from the project.
b) Result in the loss of availability of a locally important mineral resource recovery site delineated on a local
general plan, specific plan, or other land use plan?
No Impact. The subject site is not designated on the City of Carlsbad General Plan or the Zoning Ordinance, or in Specific
Plan-144 as a locally important mineral resource recovery site. As a result of the fact that the City has not designated the
subject property as an important mineral resource recovery site in any regulatory land use document, it is determined that
implementation of the proposed project will not result in the loss of availability of a locally important mineral resource
recovery site. Since no adopted regulatory land use documents, including the City of Carlsbad General Plan or the Zoning
Ordinance, designate the subject site as a mineral resource recovery location, it is concluded that no impacts would occur as
a result of implementation of the project.

would the project expose people residing or working
in the project area to excessive noise levels?
a) Exposure of persons to or generation of noise levels in excess of standards established in the local general
plan or noise ordinance or applicable standards of other agencies?
Less Than Significant Impact. Presently' the primary noise source in the vicinity of the proposed project alignment is
noise generated by vehicular traffic on I-5, Avenida Encinas, Cannon Road and Palomar Airport Road and Carlsbad
Boulevard, trains on the BNSF railroad tracks, and Encina Power Plan equipment. Upon completion of construction, the
sewer line will be underground and will not generate any perceptible noise. The lift station will however, generate noise.
Noise has been simply defined as "unwanted sound". Sound becomes unwanted when it interferes with normal activities,
when it causes actual physical harm or when it has adverse effects on health. Noise is measured on a logarithmic scale of
sound pressure level known as a decibel (dB). A -weighted decibels (dBA) approximate the subjective response of the
human ear to broad frequency noise sources by discriminating against very low and very high frequencies of the audible
spectrum. They are adjusted to reflect only those frequencies which are audible to the human ear. The Community Noise
Equivalent Level (CNEL) is the weighted average of the intensity of a sound, with corrections for time of day, and
averaged over a 24 hour period. The time of day corrections require the addition of 5 decibels to sound levels during the
evening hours (between 7 PM and 10 PM) and the addition of 10 decibels to sound levels at night (between 10 PM and 7
AM). These additions are made to account for the noise sensitive time periods during night hours when sound appears
louder due to less ambient noise.
The Noise Element of the City of Carlsbad General Plan identifies certain sound levels that are compatible with various
land uses. The Carlsbad Draft Noise Guidelines Manual, dated 1989, which is used to implement the Noise Element

requirements, indicates that sound levels up to 60 dBA CNEL are compatible with residential land uses. Residential land
uses are the closest "noise sensitive" land uses to the alignment of the proposed project.
The proposed lift station is not located in the close proximity to residential housing developments or other sensitive
receptors. The land uses around the lift station are industrial (power generating plant) in nature, which is considered in the
Noise Guidelines Manual as a "General Industrial, Manufacturing or Utilities" land use. Noise exposure levels for this use
are higher than those allowed for residential uses, up to 80 dBA CNEL as being "conditionally acceptable". The future
Coastal Rail Trail bicycle and pedestrian trail is proposed approximately 50-100 feet westerly (the exact location is not yet
known) of the lift station structure. However these pedestrians would also be subjected to extreme noise levels (several
times louder than the lift station equipment) from passing coaster trains on the adjacent railroad tracks and equipment on
the adjacent Encina Power Plant site.

Mechanical components within the lift station have the potential to exceed the 65 dBA noise level typically allowed for
pedestrian trails, neighborhood parks, and similar open space recreation uses. These components are; supply and exhaust
fans, air conditioning unit, and emergency generator(s). However, the below -grade design of the lift station will reduce
potential noise impacts significantly, and additional noise abatement measures for this equipment will include sound
enclosures and insulation, noise attenuation panels around generator rooms, and exhaust manifold silencers for the
generators.
The industrial limit of 80 dBA is significantly higher than the residential or pedestrian trail limits, and no significant
impacts to the industrial power plant uses are anticipated based on the anticipated noise levels from the lift station. With
regard to residential, the nearest residences (60 dBA limit) to the lift station site are located across (on the north side of) the
Agua Hedionda Lagoon, in the neighborhoods on Aguila Street and Kalpati Circle, a linear distance of 1,800 feet. The
noise generated by lift station operations will not be perceived by these residents.
Construction of the project (particularly the lift station grading, and trenching along the entire project length) will increase
temporary ambient noise levels. Two types of construction related noise would occur:
• Noise generated by stationary construction equipment operating along the project alignment, and
• Noise generated by construction related trucks along the alignment.
Construction noise levels for nearby receptors such as residential units generated by construction equipment can vary
substantially depending upon a number of factors. These factors include the number and type of equipment in operation at
any given time, as well as the distance and intervening topography between the construction area and the receptors. As a
result of the relatively large size of the pipeline (54-inch diameter) and the trench depth (up to 20 feet), any given nearby
location along the pipeline alignment could be subjected to construction noise for a few weeks while pipeline construction
progresses toward and then past that location. Construction equipment to be used for the project is estimated to generate
temporary short term noise levels of up to 80 dBA at a 50 foot distance. The nearest residential units will be approximately
I I0-feet east of the trench location at the closest point (northermnost point of the proposed project). This noise level drops
off approximately 6 dBA per doubling of distance. Therefore, at 100 feet horizontal distance, the short term construction
dBA could reach 73 dBA. Since the CNEL scale is 24-hour weighted, and work will only take place primarily within the
day hours, the CNEL dBA for construction -related impacts to the closest residences will not exceed allowed limits.
Further, it should be recognized that residences in this location are subjected to extreme noise levels (several times louder
than the construction equipment) from passing coaster trains on the adjacent railroad tracks and from ambient noise from
vehicular traffic travelling on nearby I-5.
Project -related construction noise would also include noise generated by construction truck activity on public streets. The
City of Carlsbad Municipal Code (Chapter 8.48) prohibits construction activity after sunset of any day, and before 7 A.M.
Monday through Friday, and before 8 A.M. on Saturday, and all day Sunday and specified holidays. The Noise Ordinance
does not set a defined noise level standard for construction activities, but simply limits the hours of construction, except for

PDP Oa-02(C) /SP 144(L) /RP 10-261 CDP 10-171HDP 10-OS/SUP 10-02 /HMP 10-03
certain very limited construction activities that do not create disturbing, excessive or offensive noise after sunset and before
7:00 AM. The significance of construction noise produced during project construction is typically assessed in accordance
with the County of San Diego Noise Ordinance. San Diego County Noise Ordinance Section 36.410 stipulates that
construction noise shall not exceed 75 dBA for more than 8 hours during any 24-hour period. Noise from haul trucks
travelling along the project alignment would generate noise levels of up to 76 dBA at a distance of 50 feet. These noise
levels would diminish rapidly with distance from the project alignment at a rate of approximately 6 dBA per doubling of
distance (70 dBA at 100 feet, etc.).
Nighttime construction may be employed for the recycled water line crossings of the Cannon Road intersection and the
Palomar Airport Road intersection. Construction necessitating use of moderate noise -producing equipment such as small
excavators, backhoes, flat bed truck and dump truck, and including pneumatic tools with compressor will be used during
this limited nighttime operation. Pursuant to adopted City policy, nighttime construction must comply with the noise
restrictions articulated in Carlsbad Municipal Code Section 8.48.010, which stipulates allowance for limited nighttime
construction pursuant to issuance of a City Manager -issued permit subject to findings that residences within 1,000 feet of
the construction will not be unduly impacted by noise from the construction_
As a result of these factors, it is determined that both operational and construction noise levels generated by the project are
anticipated to comply with City of Carlsbad Draft Noise Guidelines Manual land use noise levels, the City permitted
construction noise levels and hours, and County of San Diego Noise Policy standards. As a result, a less than significant
impact is assessed.
b) Exposure of persons to or generation of excessive groundbourne vibration or groundbourne noise levels?
Less Than Significant Impact. Construction of the project will generate temporary ground -borne vibration and noise
levels typical of soil movement and hauling activities from operations of earthmoving equipment, tunneling machines and
other large construction vehicles. However, these activities will be temporary in nature. Ground -borne vibration or
ground -borne noise levels associated with the project would have a less than significant impact.
c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without
the project?
Less Than Significant Impact. The sewer line will be underground and will not generate any perceptible noise. The
proposed project lift station will include equipment components which will have the potential to exceed the levels of noise
without the project. These components are; supply and exhaust fans, air conditioning unit, and emergency generator(s).
Noise abatement measures for this equipment will include; undergrounding much of the lift station structure, sound
enclosures and insulation, noise attenuation panels around generator rooms, and exhaust manifold silencers for the
generators. Further, the lift station is located away from sensitive residential receptors, and in an area which is adjacent to
and thus directly subjected to extreme noise levels (several times louder than the lift station equipment) from passing
coaster trains on the adjacent railroad tracks, and ambient noise from I-5 and Carlsbad Boulevard traffic. Thus, as indicated
in Section XI(a), the increase in ambient noise levels from the lift station is considered a less than significant impact.
d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels
existing without the project?
Less Than Significant Impact. During construction, the project would generate temporary increases in noise levels in the
immediate area of the construction activities. As indicated in Section XI(a), construction equipment would generate noise
levels of up to 80 decibels at a 50 foot distance. As a result of the relatively large size of the pipeline (54-inch diameter)
and the trench depth (up to 20 feet), any given nearby location along the pipeline alignment could be subjected to
construction noise for a few weeks while pipeline construction progresses toward and then past that location. The nearest
residential units will be approximately 110-feet east of the trench location at the closest point (northernmost point of the
proposed project). Again, it should be recognized that residences in this location are subjected to extreme noise levels
(several times louder than the construction equipment) from passing coaster trains on the adjacent railroad tracks, and from
vehicular traffic travelling on nearby I-5.
While project construction will create temporary increases in ambient noise levels, noise would only be generated during
daytime hours (except for limited nighttime installation of the recycled water line across the lanes of Cannon Road and

Palomar Airport Road, subject to issuance of a City Manager permit), and any sensitive receptors (such as nearby
residences) would only be exposed to construction noise during the few weeks the sewer line is being trenched and installed
nearby any given residence. For this reason, impacts associated with temporary increases in noise levels are considered less
than significant.
e) For a project located within an airport land use plan or, where such a plan has not been adopted, within 2
miles of a public airport or public use airport, would the project expose people residing or working in the
project area to excessive noise levels?
Less Than Significant Impact. The extreme southern end of the proposed sewer line alignment is located 1.96 miles from
the western property line of McClellan Palomar Airport, and 2.10 miles from the runway of that airport. The southern end
of the project alignment, from the approximate mid -point between Cannon Road and Palomar Airport Road to the EWPCF
is located within the Airport Influence Zone as.outlined in the McClellan -Palomar Airport Land Use Compatibility Plan
(ALUCP), adopted January 25, 2010 and amended March 4, 2010, prepared by SANDAG. No section of the proposed
project is situated within an identified Airport noise contour zone. The nearest zone contour (60-65 dBA CNEL) is located
on the east side of I-5. The ALUCP also includes a Safety Policy Map. The subject project is not located in any of the
identified safety hazard zones.
As a result of the above factors, no restrictions are placed upon the subject use within this contour. Except for the lagoon
bridge and above -grade portions of the sewer lift station outside the Airport Influence Area, the proposed project is a
wholly -underground allowable use. Thus, the proposed sewer line use is considered compatible with the ALUCP. As a
result, the project will not result in subjecting people residing or working in the project area to excessive noise, The project
will not create any perceptible noise. Therefore, a less than significant impact is assessed.
f) For a project within the vicinity of a private airstrip, would the project expose people residing or working in
the project area to excessive noise levels?
No Impact. No private airstrip exists in the vicinity of the subject project. As a result, no impacts will occur from
implementation of the project.

Less Than Significant Impact. The project alignment travels through the City of Carlsbad's LFMP Zones I and 3. The
project does not propose the construction of any employment generating or residential uses that would induce population
growth in the area. While the project would improve the quality and capacity of the V/C Sewer Line, the improvements are
proposed in response to the anticipated growth in the sewer service area, in accordance with the adopted General Plans of

the north Carlsbad and the Vista cities. Thus the project is considered a response to anticipated growth in the service area,
not an inducement of growth. No population increase would result from implementation of the proposed project. As a
result of the fact that the project would not induce growth, it would also not lead to secondary impacts on the environment
associated with induced growth. As a result, the impacts from the project are considered less than significant.
b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing
elsewhere?
No Impact. The project will not result in the elimination of any residential units, and no impact associated with the removal
of existing housing would occur.
c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere?
No Impact. No people or houses Will be displaced by implementation of the project. No residences exist within the
alignment of the proposed project and no replacement housing will be needed. Therefore, no impacts associated with the
construction of replacement housing would occur from the project.

i. Fire protection?
Less Than Significant Impact. The project alignment is located within the Zones I and 3 LFMP areas. City of Carlsbad
Fire Station No. 1 (1275 Carlsbad Village Dr.) serves the northern portion of the subject alignment, and Fire Station No. 4
(6885 Batiquitos Dr.). The subject project alignment is considered by the Carlsbad Fire Department to be within an
effective fire response time (within five minutes) of these stations. The project proposes no business or residential uses.
The majority of the project will be installed underground and will thus not be subject to significant fire risk. The two

structures proposed in conjunction with the project, the lift station and the channel bridge will be almost totally fireproof,
inasmuch as the lift station will be constructed with cured -in -place concrete walls and metal roof and doors, and the bridge
will be constructed of concrete supports and steel bridge.
The presence of approximately 20 construction workers (during the project construction period) at any single time could
create the potential for a construction accident or other medical emergency to occur, and could require response from the
appropriate fire station. This potential however, would not necessitate the need for new or altered fire protection facilities
or additional staff. Fire protection impacts will be less than significant.
ii. Police protection?
Less Than Significant Impact. The Carlsbad Police Department (CPD), located at 2560 Orion Way, services the entire
city of Carlsbad. Although the City has not established an official service standard for the department, CPD does maintain
a general in-house guideline that is followed in order to assure adequate police service to the community. This guideline
suggests a six -minute maximum response time anywhere within the city limits. The project dos not propose any residential
or business uses; therefore, the proposed project would not represent an increase in demand on CPD resources.
During the project construction period, theft or vandalism at the construction site or the staging areas could require a
response from CPD. While the likelihood of occurrences is unknown, their number is expected to be low. Temporary
security lighting and other security measures will be used at the staging areas where construction equipment could be
stored, and this is expected to discourage vandalism or theft. As a result of the fact that the project would not result in the
construction of residential or business structures, the likelihood of other police -dependent incidents would be low, and the
project will not require the need for new or altered police protection facilities or additional staff. Police protection impacts
will be less than significant.
iii. Schools?
No Impact. The project will not include the construction of any components that would result in an increase in population
or students. Also, no portion of the project alignment would be located adjacent to a school facility. The nearest school
facility to the proposed project alignment is Jefferson Elementary School at the corner of Jefferson Street and Tamarack
Avenue. Since no increase in demand for school services will occur, and construction activities will not interfere with any
school facilities, no impact to school services will result from the project.
iv. Parks?
No Impact. The project will not include the construction of any components which would create an increase in demand for
parks. The nearest park is the Carlsbad State Beach, which is 650 feet westerly of the northern segment of the project
alignment. As a result of the fact that no increase in demand for parks will result, and that construction activities will not
interfere with existing park facilities, no impacts to park facilities would occur from implementation of the project.
V. Other public facilities?
No Impact. The proposed project does not include residential, commercial or industrial land uses, and does not include
any components that would result in an increase in population or any public facility or infrastructure demand. The project
operations will not result in any increased traffic and will thus not result in any substantial deterioration of the public
roadway system. The project will not generate a need for other governmental services, such as libraries, hospitals, or
public housing. Construction of the project will not increase or generate the need for any of these public facilities or
services. For these reasons, it is concluded that the project will result in no impacts associated with the provision of or
maintenance of public facilities.

a) Would the project increase the use of existing; neighborhood and regional parks or other recreational
facilities such that substantial physical deterioration of the facility would occur or be accelerated?
No Impact. The proposed project does not include the construction of any population inducing uses, such as residential,
commercial or employment -opportunity business uses. As such; no increase in demand for neighborhood or regional parks
or other recreational facilities would be expected to occur from the project. The project alignment is sufficiently distant
(650 ft.) from the Carlsbad State Beach that pipeline facility construction operations would not impact the existing use of
the beach park. Thus, the project will generate no residents or workers and thus would not increase demand for parks. It
will also create no construction impacts on nearby parks. As a result, no impacts would occur.
b) Does the project include recreational facilities or require the construction or expansion of recreational
facilities, which might have an adverse physical effect on the environment?
No Impact. The project does not feature the construction of any recreational facilities, thus no impact associated with the
construction or expansion of recreational facilities would occur. It also does not create any demand for recreational
facilities because it does not generate any population, and therefore no housing or employment requirements. The project is
designed to accommodate [does not preclude] the future Coastal Rail Trail, a Citywide community pedestrian trail which is
anticipated to be aligned across the lagoon channel bridge, and along the BNSF railroad ROW. For these reasons, it is
concluded that no impacts to recreational facilities would occur as a result of implementation of the project.

Less Than Significant Impact. The project operations will not generate any observable traffic, other than daily visits for
observation monitoring by a wastewater technician and infrequent maintenance operations. Vehicular trips associated with
project construction activities would be made up of an estimated 20 commuting construction workers, and haul trucks used
for transferring soil, gravel, and materials. The construction workers would account for approximately 20 round trips per
day (40 ADT) for the 18 month period, and haul truck trips are estimated to occur at a rate of 40 round trips per day (80
ADT) for 60 total days of soil hauling. These total 120 ADT would travel on the local public roadway system, and would
thus increase the traffic by 120 ADT on adjacent roadways during this temporary 60-day soil hauling period and an
estimated 40 ADT for the balance of the 18 month construction period. Upon completion of the project, the project will not
generate any measurable traffic. Neither construction traffic increase would result in significant traffic congestion. The
street system has been designed and sized to accommodate traffic from the project and cumulative development in the City
of Carlsbad. The project is consistent with the Carlsbad General Plan, Zoning Ordinance, Specific Plan 144, and the
Carlsbad Local Coastal Program, Project operations will not significantly interfere with vehicular traffic, or with mass
transit and non -motorized travel.
Open trenching for the sewer line will be necessary in some areas. This trenching will take place within the center median
and center lanes of Avenida Encinas. It may include a temporary closure (except for local access) of small sections of
Avenida Encinas south of Palomar Airport Road. Standard, approved traffic controls will be utilized during the
construction so that traffic can continue to use convenient, parallel streets during the construction period. Major streets that
are crossed by the proposed project include Palomar Airport Road and Cannon Road. Sewer pipeline installation across
these streets is proposed via micro -tunneling and horizontal directional drilling (HDD) (respectively) construction methods.
Open trenching across the Cannon Road and Palomar Airport Road intersections for the recycled water line will take place
in one -lane segments so that only a single lane is closed to traffic at any time. Some of this work may be done during
nighttime hours to minimize disruption to traffic flow and business operations. Lane closures across these busy roadways
will be of short duration (3-days) since the recycled water line involves only a relatively shallow 5-foot deep trench. Upon
completion of open trenching backfill, the trench area will be promptly capped with asphalt to return the roadway to a
smooth driving surface. As a result, no significant impact to traffic circulation on these major streets should result. The
project will not cause a substantial increase in traffic, and a Mess than significant impact is assessed.

b) Conflict with an applicable congestion management program, including, but not limited to level of service
standards and travel demand measures, or other standards established by the county congestion
management agency for designated roads or highways?
No Impact. The San Diego Association of Govermnents (SANDAG), acting as the County Congestion Management
Agency, has designated three roads (Rancho Santa Fe Road, El Camino Real and Palomar Airport Road) and one highway
segment in Carlsbad as part of the regional circulation system. The Existing and Buildout average daily traffic (ADT) and
Existing LOS on these designated roads and highways in Carlsbad are:
Table 8: Regional Circulation Roadways in Carlsbad
Roadway
LOS
Rancho Santa Fe Road
A — D
El Camino Real
A — D
Palomar Airport Road
A — D
SR 78
F
The Congestion Management Program's (CMP) acceptable Level of Service (LOS) standard is "E", or LOS "F" if that was
the LOS in the 1990 base year (e.g., SR 78 in Carlsbad was LOS "F" in 1990). Accordingly, all designated roads and
highways are currently operating at or better than the acceptable standard LOS.
Achievement of the CMP acceptable LOS "E" standard assumes implementation of the adopted CMP strategies. Based on
the design capacity(ies) of the designated roads and highway and implementation of the CMP strategies, they will function
at acceptable levels of service in the short-term and at buildout of Carlsbad and surrounding communities.
The buildout ADT projections above are based on the full implementation of the region's general and community plans.
The proposed project is a permitted open space use and is consistent with General Plan land use Regional Commercial
designation for the project site; therefore, its traffic was used in modeling the buildout projections. Achievement of the
CMP acceptable LOS "E" standard assumes implementation of the adopted CMP strategies. Based on the design capacities
of the designated roads and highways and implementation of the CMP strategies, the designated streets will function at
acceptable level(s) of service in the short-term and at buildout. Pipeline construction at Palomar Airport Road will be
through microtunnel construction technique, which will avoid any impacts to the traffic or level of service on Palomar
Airport Road. As a result, the project will not exceed or significantly impact the level of service standard established by the
county SANDAG representatives on regional roadways in Carlsbad. Thus the project will not conflict with an applicable
congestion management program, including level of service standards and travel demand measures, or other traffic
standards.
c) Result in a change in air traffic. patterns, including either an increase in traffic levels or a change in location
that result in substantial safety risks?
No Impact. The extreme southern end of the proposed sewer line alignment is Iocated 1.96 miles from the western
property line of McClellan Palomar Airport, and 2.10 miles from the runway of that airport. The southern end of the
project alignment, from the approximate mid -point between Cannon Road and Palomar Airport Road to the EWPCF is
located within the Airport Influence Zone as outlined in the McClellan -Palomar Airport Land Use Compatibility Plan
(ALUCP), dated January 25, 2010 and amended March 4, 2010, approved by the San Diego County Airport Authority.
Although the project alignment is situated within the Airport Influence Area (AIA), the project will not involve the
construction of any aboveground structures within this AIA, and thus, will not result in any air traffic impacts. The southern
portion of the project is however, within ALUCP Review Area 2. The northern portion of the project is outside of the
Airport influence area. Projects in the Review Area 2 are subject to Airport Overflight Notification. No section of the
proposed project is situated within an identified Airport noise contour zone. The nearest zone contour (60-65 dBA CNEL)
is located on the east side of I-5. The ALUCP also includes a Safety Policy Map. The subject project is not located in any
of the identified safety hazard zones. On July 6, 2010, the City of Carlsbad has received written clearance from the San
Diego County Regional Airport Authority that the project will not require ALUC review inasmuch as the project is
consistent with the ALUCP. As a result, no impacts to air traffic would occur from the project.

Less Than Significant Impact. The proposed project will not include hazardous design features or incompatible uses.
Upon completion of construction, the only aboveground components of the project (other than the manholes which will
stand only 0-inches to 18-inches above (grade) would be the lift station structure and the channel bridge structure. Thus, no
potential for safety hazards would be expected to occur.
The project will also avoid impacts to heavily -travelled Palomar Airport Road and Cannon Road due to the proposed
microtunneling and HDD construction methods, which do not necessitate detour routing or other hazardous features or
circumstances. Also, on Avenida Encinas, where short segments of travel lanes may be temporarily closed during the
construction period, the construction contractor will be responsible for safely redirecting the traffic flow. No sharp curves
or dangerous intersections would be created as a result of the proposed project. The proposed uses, sewer trunk line, sewer
lift station, are compatible with the adjacent railroad, power plant industrial and arterial roadway uses. Impacts to safety
from design features or incompatible uses would be less than significant.
e) Result in inadequate emergency access?
Less Than Significant Impact. Temporary traffic diversions will be necessary when the two interior Avenida Encinas
traffic lanes are closed (the two outside lanes will remain open) north of Palomar Airport Road, and when Avenida Encinas
south of Palomar Airport Road is closed except for local traffic. Convenient alternative routes are available for motorists
wishing to utilize these road segments. Thus, thru-access, and access to nearby uses will not be significantly hindered.
The construction contractor will use standard adopted City of Carlsbad procedures to minimize traffic diversions.
Emergency vehicles will be able to pass through the project area without obstruction, or take a convenient alternative route
during the potential temporary closure of the short sections of Avenida Encinas south of Palomar Airport Road. Further,
open trenching across the Cannon Road and Palomar Airport Road intersections for the recycled water line will take place
in one -lane segments so that only a single lane is closed to traffic at any time. Lane closures across these busy roadways
will be of short duration (3-days) since the recycled water line involves only a relatively shallow 5-foot deep trench.
As required by the City of Carlsbad Traffic policies, any construction work within a public roadway right-of-way will be
the subject of a Traffic Control and Detour Plan. Such plans allow for contractor work in public streets while maintaining a
safe, uniform flow of traffic, including vehicular, bicycle and pedestrian traffic. The Traffic Control and Detour Plan
identifies all existing roadway improvements, shows the location and dimensions of the construction work zone, delineates
staging areas in and around the work zone as appropriate, and indicate locations of construction signs, barricades and
delineators (including cones) and detours. As required by the City, this plan also indicates the duration of the construction
work and traffic control, and must be approved by the City Traffic Engineer prior to beginning of construction within the
roadway right-of-ways. Required compliance with this City policy is sufficient to determine that this impact is less than
significant.
f) Conflict with adopted policies, plans or programs regarding public transit, bicycle, or pedestrian facilities,
or otherwise decrease the performance or safety of such facilities?

Although once completed, the project will not have any impact on the above transit service lines, construction of the project
will impact three of the four service routes through the area. Routes 101, 444 and 445 all travel down the south segment of
Avenida Encinas. Route 101 travels this route to access the Kaiser Permanente offices south of the EWPCF, and Routes
444 and 445 travels to the Carlsbad Poinsettia Transit Station, also located south of the EWPCF on Avenida Encinas.
Temporary traffic diversions will be necessary when Avenida Encinas south of Palomar Airport Road is closed except for
local traffic. A convenient alternative route will be made available for NCTD to use to access these destination points
(Kaiser Permanente and Poinsettia Transit Station) from Poinsettia Lane (from the south), rather than from Palomar Airport
Road (from the north). A mitigation measure is included which will provide for advance notice and coordination with
NCTD of this imminent, temporary closure of this Avenida Encinas segment. This mitigation measure is indicated below.
Route 321 crosses the project alignment across Cannon Road, but will not be impacted by construction since pipe
installation at Cannon Road will be via HDD tunneling, which does not necessitate any modification of traffic lanes or
practice.
No bicycle racks or other alternative transportation features would be demanded by the project since it does not propose
business, employment, residential, commercial, health, or other high -demand uses. No bicycle or pedestrian facility
perfonnance would be impacted significantly, nor would the: safety of such facilities be affected by implementation of the
project.
TRAF-1 Prior to the commencement of development of the proposed project, the developer shall coordinate with
NCTD to determine an acceptable routing during the construction period of NCTD transit service for buses
that are scheduled on Avenida Encinas, south of Palomar Airport Road, within the alignment of the proposed
project.

a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board?
Less Than Significant Impact. Under Section 402 of the Federal Clean Water Act (CWA) the Regional Water Quality
Control Board (RWQCB) issues NPDES permits to regulate discharges to "waters of the U.S." which include rivers, lakes,
and their tributary drainages. Waste discharges include discharges of storm water and construction project discharges. A
construction project resulting in the disturbance in excess of one acre requires an NPDES pen -nit. Construction project
developers are also required to prepare a SWPPP plan. As a result of the fact that the project would be required to comply
with the waste discharge prohibitions and water quality objectives established by the RWQCB and the City of Carlsbad (as
a co-permittee), impacts related to this issue would be less than significant.
b) Require or result in the construction of new water or wastewater treatment facilities or expansion of
existing facilities, the construction of which would cause significant environmental effects?
No Impact. The proposed project is needed to replace the; existing Agua Hedionda Lift Station (AHLS) and significant
portions of the Agua Hedionda sewer trunk line because the latter is nearing the end of its useful life and does not have
sufficient capacity to convey future project wastewater flows. The AHLS is part of the Vista/Carlsbad Sewer Interceptor
system, which covers the Vista/Carlsbad drainage basin (sewer service area) and drains sanitary sewage generated by urban
development from this basin to the EWPCF. The project is planned of a size and scale which will handle the projected
build -out sewage anticipated from the service area. The project will not result in an increase in quantity of wastewater
generation already handled by the Encina Wastewater Treatment Plant.
The proposed project will connect to the existing sewer tributary lines at the north end of the project alignment, and future
recycled water lines at the north and south ends of the project alignment. It will not impact any other sewer or other utility
lines in the area. Thus, impacts to local sewer collection facilities in the area will be avoided. The project would not
necessitate the construction of, or expansion of any new water, sewer or wastewater treatment facilities.
Further, the project will not require the construction of any habitable structures, such as residences, commercial or retail
uses, or businesses; therefore it would not generate new wastewater flows. As a result, inasmuch as the project does not
include provision of any uses that would generate wastewater flows, no new or expanded wastewater facilities would be
needed to accommodate the project. No impacts would occur from implementation of the project.
c) Require or result in the construction of new storm water drainage facilities or expansion of existing
facilities, the construction of which could cause significant environmental effects?
No Impact. The City of Carlsbad Master Plan of Drainage Facilities (2007) indicates that the following drainage facilities
and structures exist and/or are proposed within or near the alignment of the proposed project:

During construction, BMPs would be implemented to prevent: construction -tainted runoff (containing sediments, oil, grease,
etc.) into the storm drain system. The BMPs will include a variety of measures to control these pollutants, such as the use
of sandbags and straw bales to block drain inlets to prevent discharge from entering the storm drain system, and other
temporary protections. Once completed, the project would not increase storm water flows in the area of the project. As a
result, the project will not result in the need for modification or addition of new storm water drainage facilities or expansion
of existing facilities, and therefore, no impacts would occur.
d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are
new or expanded entitlements needed?
Less Than Significant Impact. The proposed project involves the placement of an underground sewer trunk line, a sewer
lift station and a bridge structure to support the sewer line over the Agua Hedionda channel. The project will upgrade and
replace sewer trunk collection facilities, but wilt not result in any substantial overall changes to local or regional sewer or
water supplies. Construction will require temporary use of water for dust control; however, this relatively small amount of
water use will not affect local or regional water supplies and would not require any new expanded entitlements. Impacts
are considered less than significant.
The project also involves the provision of a 12-inch (diameter) recycled water line. This line will serve to distribute
recycled water from the EWPCF to the northern region of Carlsbad. The water will be used primarily for landscape
irrigation throughout this northern section of Carlsbad. Thus, the project will contribute to an increase in the availability of
water supply for the northern portion of Carlsbad.
e) Result in a determination by the wastewater treatment provider, which serves or may serve the project that
it has adequate capacity to serve the project's projected demand in addition to the provider's existing
commitments?
Less Than Significant Impact. While the project will transport wastewater, the project will not generate wastewater. The
proposed sewer line and lift station will replace an existing line and lift station. The project will improve the current
wastewater infrastructure, which will subsequently be able to handle increased flow to the EWPCF. These increased flows
can be accommodated within the EWPCF capacity. Therefore, the project would result in more efficient and reliable
wastewater transport to the Encina Wastewater Plant. As a result, impacts would be less than significant.
f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal
needs?
Less Than Significant Impact. The project will not include any components (such as residences or business offices) that
would require regular solid waste disposal services over the life of the project. During construction, demolished portions of
the pipeline, existing lift station, trestle bridges and concrete: overflow basin would be disposed of in accordance with local,
state and federal requirements. Soil excavated during project construction would be temporarily stockpiled at the staging
areas and would be reused, as appropriate, to fill trenches following pipe placement. While the project will generate some
debris that would require disposal, it will be relatively minimal, and therefore impacts to landfills will be less than
significant.
g) Comply with federal, state, and local statutes and regulations related to solid waste?
Less Than Significant Impact. The project will be required to comply with applicable elements of AB 1327, Chapter 18
(California Solid Waste Reuse and Recycling Access Act of 1991) and other applicable local, state and federal solid waste
disposal standards; therefore impacts associated with this issue are less than significant.

Potentially Significant Unless Mitigation Incorporated. The following discussion demonstrates how, with mitigation,
the proposed project would result in less than significant impacts with respect to the potential for substantially degrading
the quality of the environment; substantially reducing the habitat of a fish or wildlife species; causing a fish or wildlife
population to drop below self-sustaining levels; threatening to eliminate a plant or animal community; reduce the number or
restrict the range of an endangered, or rare or threatened species; or eliminate important examples of major period of
California history or prehistory.
Potential to degrade the quality of the environment.
The project would not have the potential to degrade the quality of the environment.. As indicated in the foregoing
environmental analysis; No Impact, a Less Than Significant Impact, or a Potentially Significant Impact Unless
Mitigation Incorporated is assessed to occur for each and every environmental issue addressed as a result of
implementation of the project. In cases where the impact is assessed at Potentially Significant Impact Unless Mitigation
Incorporated, mitigation measures are included in the project's MMRP, which will minimize impacts to a level of
insignificance.

Vegetation communities which would be impacted through implementation of the project, includes Die -ail Coastal Sage
Scrub (DCSS), Developed Lands (DEV), disturbed lands (DIS) and Eucalyptus Woodlands (EUC). Thus, project related
impacts will occur to one sensitive upland vegetation association (CDSS) and this is considered a significant impact. No
direct impacts will occur to sensitive wetland or riparian habitats. No impacts to waters of the U.S. will result from the
project. Thus, no impacts to fish will result. Impacts to the remaining impacted vegetation communities (excluding
Developed Lands) are considered significant unless HMP-required mitigation credit (Lake Calavera Mitigation Credit) is
complied with. Impacts to Developed Lands are not significant.
During construction of the project, machinery necessary to accomplish the trenching and pipe laying work will be located
on urbanized pads and streets, and will maintain a minimum 10 feet buffer from adjacent non -impacted sensitive vegetation
communities. Also, staging areas for pipes, machinery, materials and tools will be on previously -graded urbanized areas, or
within adjacent traffic lanes which will be closed to traffic. Backhoe tractors will be primarily utilized for trenching, with
the spoils temporarily laid directly adjacent to the trench, a minimum 10-foot from any sensitive vegetation or water.
Trucks to transport materials to the site and other smaller vehicles will access the area and park on the public streets and on
the urbanized pads. Thus, direct temporary impacts to adjacent sensitive habitats will be avoided.
However, the project may have the potential for indirect impacts on rare nesting or breeding birds in the sensitive habitats
located in the adjacent Agua Hedionda Lagoon area because of impacts resulting from temporary, construction -related
noise. Listed birds not identified on or near the site but potentially impacted by indirect impacts because they forage or rest
in or near the lagoon include the Great blue heron, Elegant tern, and the California Brown pelican, all species that are listed
as endangered or threatened and may be found in and around the adjacent open water. These potential noise impacts would
be considered impacting only if the noise created a disruption of nesting activities, and thus only during the bird
nesting/breeding season, generally from January 15 to September 15 of any year. Thus, if project construction in locations
adjacent to Agua Hedionda lagoon is contemplated during this time, the project would need to implement mitigation
measures to ensure any construction noise impacts do not significantly impact these nesting migratory birds. These birds
nest in trees, shrubs and on the ground.
As a result of these factors, with the incorporation of Mitigation Measures BI0-1 through BIO-13 which will ensure
provision of additional protections on rare plants and animals during construction, and will ensure the revegetation of
sensitive habitats, the project will not have the potential to substantially reduce the habitat of a fish or wildlife species,
cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community,
or reduce the number or restrict the range of a rare or endangered plant or animal.
Have the potential to substantially eliminate important examples of the major periods of California history or prehistory.
The proposed project would not eliminate important examples of major periods of California history or prehistory. With
regard to history, based on an archaeological literature and records search of historic maps and aerial photographs, no
buildings or structures have been recorded within the project area of potential effect. With regard to prehistory, records
investigations for the Archaeological Resources Survey, dated May 2009, concluded that two archaeological sites were
previously recorded adjacent to the project area and one site was previously recorded within the impact area. During a
2009 archaeological field survey, no cultural material was observed within the project area.
However, based on monitoring of geotechnical testing, it is suggested that intact cultural deposits may be present beneath
the existing fill soils that cover portions of the project alignment. Therefore, if the proposed pipeline would be trenched
into native soils beneath these fills, which. is anticipated, there is a potential for encountering cultural resources. Given the
number of archaeological sites in the area and the nature of the soils, there is a potential for archaeological resources to
exist within a subsurface context, with little or no evidence on the existing soil surface. Based on this, a monitoring
program must be implemented for the project, as detailed in the following mitigation measures.
The Native American Heritage Commission records show no indication of Native American cultural resources within 1/2
mile of the project, although the field survey referenced above suggests that there are Native American cultural resources in
proximity to the project area. As a result, the project could also result in a significant impact to Native American resources
if mitigation is not included.

With the incorporation of Mitigation Measures CUL-I and CUL-2, which will ensure provision of construction monitoring
for prehistoric deposits, the project will not have the potential to eliminate important examples of major portions of history
or prehistory. Therefore, impacts from the project would be less than significant.
b) Does the project have impacts that are individually limited, but cumulatively considerable? ("Cumulatively
considerable" means that the incremental effects of a project are considerable when viewed in connection
with the effects of past projects, the effects of other current projects, and the effects of probable future
projects?)
Less Than Significant Impact. Cumulative impacts are defined as two or more individual effects that, when considered
together, are considerable or that compound or increase the severity of other environmental impacts. The cumulative
impact from several projects can be quantified as the change in the environment that results from the incremental impact of
the development when added to the impacts of other closely related past, present, and reasonably foreseeable or probable
future developments. Cumulative impacts can result from individually minor, but collectively significant, developments
taking place over a period of time.
CEQA Guidelines, Section 15130(a) and (b) states:
(a) Cumulative impacts shall be discussed when theproject's incremental effect is cumulatively considerable.
(b) The discussion of cumulative impacts shall reflect the severity of the impacts and their likelihood of
occurrence, but the discussion need not provide as great detail as is provided of the effects attributable to the
project. The discussion should be guided by the standards ofpracticality and reasonableness.
Development Projects: Three development projects are proposed in the vicinity of the subject project.
1. The Poseidon Desalination Plan is a50-million gallons per day (MGD) seawater -to -potable water Reverse
Osmosis (RO) industrial plant. The plant will include a desalination plant, pipelines, electrical transformers,
and solids handling building. Once operational, it is anticipated that the plant will have the capacity to deliver
water to the city of Carlsbad and other regional partners. The project has been approved and will be
constructed south of the proposed lift station site.
The NRG Power Plant Expansion involves construction of a second power plant on the existing Encina Power
Plant site. An application for certification for this expansion has been submitted to the California Energy
Commission; however the City of Carlsbad is officially opposing the project. The project would be located on
property immediately south-east of the proposed lift station site. It is estimated to generate approximately 540
megawatts of power for the region. The project would contain two 14-story smokestacks and 9 to 10-story
buildings.
The NCTD Railroad Double -Tracking project its a future project proposed by the California Department of
Transportation and Amtrak for NCTD. It involves the addition of a parallel railroad track along the subject
section of track within Carlsbad. The project will necessitate an additional bridge across the lagoon channel.
It is anticipated that the second track will be installed easterly of the existing track.

If all of these projects were initiated and constructed at the same time, potentially significant impacts with respect to three
environmental issues could occur:
1. Air quality — Fugitive dust and construction equipment emissions;
2. Biological Resources — Possible presence and impacts to sensitive species and habitats; and
3. Cultural Resources — Possible unearthing of cultural and paleontological resources through excavation.
It would be expected however, that all environmental impacts associated with these development projects, plus this massive
sewer CIP project, could be mitigated to levels that would be less than significant by means of mitigation measures similar
in content to those identified in this Environmental Initial Study. However, possible environmental impacts resulting from
the NRG Power Plant expansion project have not been analyzed in this document inasmuch as that project has not yet been
specifically defined and the impacts are not known at this time. As a consequence, and assuming mitigation measures
similar to those found in this Study, these projects, excluding the NRG Power Plant expansion project, in combination with
the proposed project would not result in significant cumulative impacts.

In terms of assessing whether the project's incremental contribution to greenhouse gas emissions is "cumulatively
considerable" pursuant to Section 15130 of the State CEQA Guidelines, the extremely minor contribution of the project to
global greenhouse gas emissions suggests that this project does not contribute "cumulatively considerable" greenhouse gas
emissions. It is beyond the scope of this Environmental Initial Study to determine the greenhouse gas effects of all past,
present, and probably future projects producing related or cumulative impacts.5 Further, it is not possible to rely on a
summary of projections contained in the Carlsbad and/or Vista General Plan because the applicable adopted local and
regional planning documents do not provide the necessary analyses of greenhouse gas emissions. Consequently, while the
global significance of climate change may be acknowledged, determining the cumulative contribution relative to the
proposed project and other closely related past, present, and reasonably foreseeable or probable future related projects
would be speculative, and therefore, is not pursued further in this Environmental Initial Study. Thus, it is concluded that
impacts of the proposed project would be less than significant.
c) Does the project have environmental effects, which will cause substantial adverse effects on human beings,
either directly or indirectly?
Less Than Significant Impact. Potential adverse effects on the human population have been evaluated in preceding
sections 'of this checklist. The incorporation of design measures identified in the project description, applicable City of
Carlsbad policies and standards, and applicable state and federal guidelines, will ensure that no substantial adverse effects
on human beings, either directly or indirectly, will result from the project. Impacts of the proposed project would be less
than significant.
XVIII. EARLIER ANALYSES
Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, one or more
effects have been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). In this
case a discussion should identify the following on attached sheets:
a) Earlier analyses used. Identify earlier analyses and state where they -are available for review.
b) Impacts adequately addressed. Identify which effects from the above checklist were within the scope of
and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether
such effects were addressed by mitigation measures based on the earlier analysis.
c) Mitigation measures. For effects that are "Less Than Significant with Mitigation Incorporated," describe
the mitigation measures, which were incorporated or refined from the earlier document and the extent to
which they address site -specific conditions for the project.

LIST OF MITIGATING MEASURES (IF APPLICABLE)
To mitigate potentially significant project impacts, the following mitigation measures shall be applied to the
development of the proposed project:
Air Quality
AQ-1
All construction equipment will be maintained at appropriate mechanical and electronic tuning levels per the
manufacturer's specifications. Diesel equipment standing idle for more than five minutes shall be turned
off. This would include dump trucks waiting to deliver or receive soil, gravel, aggregate or other bulk
materials.
Biological Resources
BI0-1
Mitigation for permanent and temporary impacts to upland vegetation communities (HMP Habitat Groups D, E
and F) will be mitigated by debiting the appropriate acreage (total 1.20 acres) from the Lake Calavera Mitigation
Parcel at the ratios indicated in Table 4 above (except Diegan coastal sage scrub mitigation acreage shall include a
minimum 1:1 creation component within the vicinity of the impacts, as indicated in Mitigation Measure #2 below).
The Lake Calavera property was identified in the City's Habitat Management Plan as a public project mitigation
parcel for municipal projects. The total acreage available for credit at its inception was 186.55 acres.That acreage
is available to mitigate -for habitat impacts from City projects on an acre -for -acre basis regardless of the type of
habitat being impacted, except for Group A, B or C habitat groups, none of which are impacted by the proposed
project. The mitigation provided for each City project by the Lake CaIavera parcel is tracked and reported on an
annual basis in the City's HMP Annual Report. As of the end of the last reporting period (October 2009), a total of
183.8 acres of mitigation land was still available.
BI0-2
Pursuant to Conservation Standards 7-8 and 7-9 (p. D-115) of the HMP, the project applicant shall mitigate for the
loss of 0.09 acre of coastal sage scrub by creation of at least 0.09 acre (no net loss) of creation of coastal sage
scrub in a location acceptable to the Carlsbad Planning Department and the Wildlife Agencies. Upon agreement as
to the selected site, the applicant shall prepare a restoration program for review and approval by the City and
Wildlife Agencies. The restoration program shall include a five-year maintenance and monitoring program, with a
requirement to meet City/Wildlife Agencies -approved success criteria. This restoration program shall be approved
prior to the commencement of any clearing of coastal sage scrub associated with project construction. The
restoration program shall include site preparation guidelines, implementation monitoring, perfonnance standards,
long-term maintenance and monitoring methodology, and contingency measures with a commitment to funding.
BIO-3
In order to avoid impacts to adjacent open space habitats during construction, all impacted open space interfaces
will require temporary orange construction fencing which clearly delineates the edge of the approved limits of
grading and clearing and environmentally sensitive areas beyond. This fencing shall be installed in all areas
adjacent to protected open spaces, and shall be installed prior to construction, and maintained for the duration of
construction activity. Fencing shall be installed in a manner that does not impact habitats to be avoided. The
applicant shall submit to the City for approval, at least seven days prior to initiating project impacts, the final plans
and photographs for initial clearing and grubbing of habitat and project construction. These final plans shall
include photographs that show the fenced limits of impact and all areas to be impacted or avoided. If work occurs
beyond the fenced or demarcated limits of impact, all work shall cease until the problem has been remedied and
mitigation identified, to the satisfaction of the biological monitor. Temporary orange construction fencing shall be
removed upon project completion of construction of the; project.

BI0-4
The developer shall hire a biological monitor to monitor the construction operations. The biological monitor shall
have the ability to halt construction work, if necessary and confer with the City and Wildlife Agencies to ensure
the proper implementation of species and habitat protection measures. The biologist shall report any violation to
the USFWS within 24 hours of its occurrence. The biological monitor shall be present to monitor clearing,
grading, and construction activities in the vicinity of biological open space areas. The biological monitor shall have
the authority to stop construction and require additional precautions or conservation measures to protect the
proposed open space preserve areas, including the wildlife movement corridor, as necessary. Implementation of
this measure shall be verified by the City prior to and concurrent with construction.
BI0-5
Prior to the commencement of any ground -disturbing activities (i.e., clearing, grubbing, trenching, grading) that
occur between January 15 and September 15, a biological survey by a qualified biologist shall be conducted of the
project area. If active raptor and/or migratory bird nests are observed during the construction phase, a buffer area
of adequate width (typically 500 feet), as determined by the monitoring biologist, shall be established between the
construction activities and the nest so that nesting activities are not interrupted. To avoid potential impacts, trees
shall be removed outside of the breeding season of local raptor species (trees shall be removed between September
15 and January 15). Noise attenuation and buffer (if required) shall remain in place until the construction activities
are completed or the nest.is,no longer active. Implementation of this measure shall be verified by the City.
BI0-6
Construction noise created during the breeding season that could affect the breeding of the California gnatcatcher,
migratory songbirds and other bird species associated with the adjacent sensitive open water, wetlands, riparian,
and coastal sage scrub habitat shall be avoided. This restriction can be waived by the City, with concurrence from
the Wildlife Agencies, upon completion of a breeding/nesting bird survey of the area in accordance with the
Migratory Bird Treaty Act. A biological monitor of the construction operation is required. If nests are present, no
loud construction (exceeding 60 dBA hourly average, adjusted for ambient noise levels, at the nesting site) may
take place within 500 feet of active nesting sites during the nesting/breeding season (January 15 through
September 15).
BI0-7
The developer shall train all contractors and construction personnel on the biological resources adjacent to portions
of this project and ensure that training is implemented by construction personnel. At a minimum, training shall
include: l) the purpose for resource protection; 2) a description of the gnatcatcher and its habitat; 3) limiting
activities, vehicles, equipment, and construction materials to the fenced project footprint to avoid sensitive
resource areas in the field (i.e., avoided areas delineated on maps or on the project site by fencing); 4) the protocol
to resolve conflicts that may arise at any time during the construction process; and, 5) the general provisions of the
Endangered Species Act, the need to adhere to the provisions of the Endangered Species Act, the penalties
associated with violating the Endangered Species Act.
BI0-8
In order to adequately protect the adjacent open spaces, the applicant shall ensure that the following mitigation
measures are implemented during project construction:
• Employees shall strictly limit their activities, vehicles, equipment and construction materials to the
fenced project footprint;
• Pets of project personnel shall not be allowed on the project site;
Disposal or temporary placement of excess fill, brush or other debris shall not be allowed in waters of the
United States or their banks;
• All equipment maintenance, staging, and dispensing of fuel, oil, coolant, or any other such activities
shall occur in designated areas within the fenced project impact limits and in such a manner as to prevent
any runoff from entering offsite open spaces, and shall be shown on the construction plans. Fueling of

equipment shall take place within existing paved areas greater than 100 feet from the Agua Hedionda
Lagoon channel shore. Contractor equipment shall be checked for leaks prior to operation and repaired as
necessary. "No -fueling zones" shall be designated on construction plans; and
Night lightin-, if any, of construction staging areas shall be of the lowest illumination necessary for
human safety, selectively placed, shielded, and directed away from adjacent natural habitats.
BI0-9
The hydroseed mix or landscape mix in areas adjacent to open spaces shall not involve the use of invasive exotic
seeds or plants. The list of invasives shall be those identified on List A and List B of the California Exotic Plant
Council's List of Exotic Plants of Greatest Ecological Concern in California, as of October, 1999, and updated if
applicable. Implementation of this measure shall be verified by the City during review of the Erosion Control
Plans.
BIO-10
During construction,, the project applicant shall install temporary silt barriers along the limits of project impacts
(including construction staging areas and access routes) adjacent to open space habitats to prevent additional
habitat impacts and prevent the spread of silt from the construction zone into adjacent habitats to be avoided. Silt
fencing shall be installed in a manner that does not impact habitats to be avoided. All work activities occurring
near the Agua Hedionda Lagoon channel in particular will utilize silt fencing to completely control any disturbed
soils from entering the Agua Hedionda Lagoon channel. Runoff from project construction and landscaped areas
shall not be allowed to enter the channel. All runoff will remain within landscaped areas or be filtered through
appropriate storm drain facilities.
13I0-111'rior to beginning construction work, the project contractor shall notify the City Engineer, City Planner
and Coastal Commission Staff as necessary, of the completion of a final, site specific, Spill Contingency Plan that
outlines actions to be taken in the event that an accidental discharge of construction fluids occurs. Such Spill
Contingency Plan shall include, at a minimum, the following requirements:
a. In the event that a "frac-out," (escape of bentonite slurry into the environment) or other spill or accidental
discharge of drilling fluids occurs during the drilling operations, all construction shall cease and shall not
recommence except as provided below:
b. Following discovery of the "frac-out," spill or accidental discharge of drilling fluids, the applicant shall
immediately implement the above stated Spill Contingency Plan. No work shall continue until all spilled fluids
have been contained and/or removed and measures taken to prevent a recurrence consistent with the approved
contingency plan. If the spill or accidental discharge results in a change to the approved project description or to
the scope of the impacts to resources, the permittee shall notify the biological monitor to immediately conduct an
assessment of the biological impacts, and submit to the City Planner, and Executive Director of the California
Coastal Commission as necessary, a revised project and restoration plan prepared by qualified professional(s) that
provides for (1) necessary revisions to the proposed project to avoid further spill or accidental discharge of fluids;
and (2) restoration of the area(s) affected by the spill or accidental discharge to pre -project conditions. The revised
project and restoration plan shall be consistent with any applicable requirements of the USFWS, CDFG and/or San
Diego RWQCB. The revised project and restoration plan shall be processed as an amendment to the coastal
development permit. The trenchless construction operations may not recommence until after an amendment to this
permit is approved by the City Planner, and Executive Director of the California Coastal Commission as necessary,
unless the City Planner, and the Executive Director as necessary, determines that no amendment is legally
required.
BIO-12
Prior to removal of the existing sewer and/or gas trestle bridges or construction of the new bridge over the Agua
Hedionda Lagoon channel, the project proponent shall apply for and receive approval of a Nationwide Permit 12
(Utility Line Activities) pursuant to Section 10 of the River and Harbors Act. This bridge removal and
construction activity shall also necessitate water quality certification issued by the San Diego Regional Water

Quality Control Board pursuant to Section 401 of the Clean Water Action, and issuance of a Streambed Alteration
Agreement with the California Department of Fish and Game. No additional mitigation beyond removal of the
existing trestle bridges is anticipated to be required.
Cultural Resources
CUL-1
Prior to the commencement of around -disturbing activities, the project developer shall retain a qualified
archaeologist to monitor ground -disturbing activities. The qualified archaeologist shall be on -site during all
grading, trenching, and other ground -disturbing activities unless otherwise agreed upon by the archaeologist and
City Staff. In the event any potential cultural resource is uncovered during the course of the project construction,
ground -disturbing activities in the vicinity of the find shall be redirected until the nature and extent of the find can
be evaluated by the archaeological monitor. If cultural resources are encountered, the archaeologist shall have the
authority to temporarily halt or redirect grad ing/trenching while the cultural resources are documented and assessed.
If significant resources are encountered, appropriate mitigation measures must be developed and implemented. If
any human remains are discovered, the County Medical ]Examiner shall be contacted. In the event that the remains
are determined to be of Native American origin, the Most Likely Descendant, as identified by the Native American
Heritage Commission, shall be contacted in order to determine proper treatment and disposition of the remains.
Recovered artifactual materials shall be cataloged and analyzed. A report shall be completed describing the
methods and results of the monitoring and data recovery program. Artifacts shall be curated with accompanying
catalog to current professional repository standards or the collection will be repatriated to the appropriate Native
American Tribe(s), as specified in the pre -excavation agreement.
CUL-2
Prior to the commencement of ground disturbing activities, the project developer shall retain the services of a Native
American monitor. The purpose of this monitoring will be to allow for tribal observation of trenching excavation
including formalized procedures for the treatment of Native American human remains and burial, ceremonial, or
cultural items that may be uncovered during any ground disturbance activities. Prior to implementation of the
monitoring, a pre -excavation agreement shall be developed between the appropriate Native American Tribe and the
City of Carlsbad. The Native American representative(s) shall attend the pre -grading meeting with the contractors
to explain the requirements of the program. The Native American monitor shall be on -site during all grading,
trenching, and other ground -disturbing activities unless otherwise agreed upon by the monitor and City Staff.
CUL-3
Prior to any excavation or trenching into undisturbed, older Pleistocene sediment, the project developer shall retain
a qualified paleontologist during construction excavations within these sediment deposits, if any, to observe
construction excavations. In the event that any unique paleontological resources are encountered, the resources
shall be salvaged, recorded, and curated, under the direction of the monitoring paleontologist.
Geolow and Soils
GEO-1
Grading and construction of the . southern bridge abutment shall comply with the geotechnical
recommendations contained in the Geotechnical Evaluation prepared by Ninyo & Moore, dated August 3,
2009, in order to reduce the potential for settlement due; to seismically -induced liquefaction or lateral spread.
These recommendations shall include the use of deep foundations and the removal and recompaction of
surface soils prior to construction.

Hazards and Hazardous Materials
HAZ-1
A site -specific Health and Safety Plan (HASP) shall be prepared prior to subsurface construction activities in the
vicinity of, (a) the lift station site and (b) Avenida Encinas just south of Palomar Airport Road. The HASP shall be
prepared in accordance with the requirements of Occupational Safety and Health Administration (OSHA) standards,
and with the California OSHA requirements for hazardous waste operations and emergency response regulations.
The HASP shall be reviewed and signed by a Certified Industrial Hygienist and include a community health and
safety component. Anyone performing subsurface work in these areas should be alerted to the potential for
encountering petroleum hydrocarbons and/or pesticides in soil and petroleum hydrocarbons and/or VOCs in
groundwater and have received the appropriate training in accordance with the approved site -specific Health and
Safety Plan (HASP).
HAZ-2
A Soil Management Plan (SMP) shall be prepared prior to subsurface construction activities in the vicinity of-, (a)
the lift station site, (b) approximately 300-400 feet south of the lift station site, (c) Avenida Encinas just south of
Palomar Airport Road, and in Avenida Encinas just south of Cannon Road and 400-500 feet north of Palomar
Airport Road, if dewatering activities are detennined to be necessary. If dewatering activities are to be performed
during construction, the SMP should include a groundwater management component for dewatering activities. If
dewatering activities are proposed to be discharged to surface waters or the sewer systems the concentrations of
metals in the extracted groundwater should meet the requirements provided in the permit from either the RWQCB
(General Waste Discharge Requirements and NPDES permit or the City of Carlsbad. The SMP shall be prepared by
a professional environmental consultant in accordance with the County of San Diego Department of Environmental
Health's Site Assessment -and Mitigation Manual, RWQCB guidelines, and the standard of care of the industry.
HAZ-3
Prior to any excavation or trenching, the construction contractor shall prepare a contingency plan documenting the
procedures to be used should an unexpected pocket of hazardous materials be encountered during excavation and/or
trenching activities. This plan shall be reviewed and approved by the City Engineer.
HAZ-4
A qualified air monitor shall be retained to monitor air quality during trenching and grading operations. Air
monitoring shall be conducted using a portable photoionization detector (PID). This instrument is capable of
detecting both petroleum hydrocarbons and organic solvents and will provide assurance that construction workers
are not inadvertently exposed to potentially harmful organic vapors.
Transportation/Traffic
TRAF-1
Prior to the commencement of development of the proposed project, the developer shall coordinate with NCTD to
determine an acceptable routing during the construction period of NCTD transit service for buses that are
scheduled on Avenida Encinas, south of Palomar Airport Road, within the alignment of the proposed project.

Agua Hedionda Sewer project
SCH #2010081053
The California Department of Transportation (Caltrans) received a copy of the Mitigated
Negative Declaration (MND) for the proposed Agua Hedionda Sewer Lift Station and
Gravity and Force Mains project (SCH 92010081053), in proximity to Interstate 5 (I-5).
Caltrans has the following comments:
The project should not interfere with future I-5 widening plans that are identified in the I-5
North Coast Corridor project DEIIZ/DEIS that is currently out for public review. Please
coordinate with Caltrans on any questions or issues regarding future I-5 widening at it relates
to this proposed project.
Any work performed within Caltrans right-of-way (RIW) will require discretionary review and
approval by Caltrans and an encroachment permit will be required for any work within the
Caltrans' R/W prior to construction.
If you have any questions on the comments Caltrans has provided, please contact Leila
Ibrahim of the Development Review Branch at (619) 688-6954.
Sincere'.

Pam,
The Department of Fish and Game has not and will not review the subject MND, and therefore will not determine
whether the proposed project is consistent with the HMP. However, we defer to the USFWS on this one.

Pam,
The Service concurs that the Agua Hedionda Sewer Lift Station and Gravity and Force Mains Mitigated Negative
Declaration (MND) is consistent with the City's Habitat Management Plan (HMP) provided the mitigation measures as
stated in the MND are implemented. The Service would agree to the mitigation going to a location other than Lake
Calavera if an appropriate site within the Agua Hedionda Management Area with protection and management in
perpetuity can be found.

Dear Ms. Drew:
INITIAL STUDY AND MITIGATED NEGATIVE DECLARATION (IS/MND) FOR CITY OF
CARLSBAD (CITY); AGUA HEDIONDA SEWER LIFT STATION AND GRAVITY AND
FORCE MAIN (PROJECT); STATE CLEARINGHOUSE NO. 2010081053
We understand the City may be pursuing Clean Water State Revolving Fund (CWSRF)
financing for this Project. As a funding agency and a state.agency with jurisdiction by law to
preserve, enhance, and restore the quality of California's water resources, the State Water
Resources Control Board (State Water Board) is providing the following information and
comments for the California Environmental Quality Act (CEQA) document prepared for the
Project.
The CWSRF.Program is partially funded by the United States Environmental Protection Agency
(USEPA) and requires additional "CEQA-Plus" environmental documentation and review. Four
information sheets are included that further explain the environmental review process and
additional federal requirements in the CWSRF Program. In addition, an environmental
evaluation form is included for the City to submit should it pursue State Water Board funding.
The State Water Board can consult directly with ,agencies responsible for implementing federal
environmental laws and regulations. Any environmental issues raised by federal agencies or
their representatives will need to be resolved prior to State Water Board approval of a CWSRF
financing commitment. For further information on the CWSRF Program environmental review
requirements please contact Ms. Michelle Lobo at (916) 341-6983.
It is important to note that prior to a CWSRF financing commitment, projects are subject to the
provisions of the Federal Endangered Species Act and must obtain approval from the
United States Fish and Wildlife Service (USFWS), and/or National Marine Fisheries Service
(NMFS) for any potential effects to special status species. Please be advised that the State
Water Board can consult with the USFWS, and/or NMFS on behalf of the City regarding all
federal special status,species the Project has the potential to impact if the Project is to be
funded under the CWSRF Program.
In addition, CWSRF projects must comply with federal laws pertaining to cultural resources,
specifically Section 106 of the National Historic Preservation Act. The State Water Board has
been delegated responsibility for carrying out the requirements of Section 106 under a

Subject: Agua Hedionda _Sewer Lift MND
Dear Ms. Drew:
These comments on the Agua Hedionda Sewer Lift Station project are made on
behalf of Preserve Calavera. Preserve Calavera is a grassroots conservation
organization whose goal is to preserve, protect and enhance the natural
resources of coastal north San Diego County. This project is replacement of an
existing facility, on a site that was already impacted by the existing sewer plant
and pipeline. However, the proposed project could cause further direct and
indirect impacts to the natural resources of this area, primarily the Agua Hedionda
watershed and lagoon.
We believe that with some modifications to the current project plans that there
could be a significant reduction in these adverse impacts and this could be done in
a way that still fully meets the objectives for this project.
The following are our specific comments on this project:
Bridge to provide second roadway access
Currently there is`a very simple structure to support pipes. The project proposes
to replace this with a much more substantial bridge that would accommodate
vehicles and thereby provide a secondary road access to the site. While this new
bridge would remove support structures from the waterway, it would cause
significant direct habitat impacts. We think. it could also cause additional indirect
impacts associated with vehicle traffic and other use of this bridge in an area that
previously would be very undisturbed.
The MND indicates that only one daily vehicle trip to the site is anticipated for
inspection and periodic additional trips for maintenance. Since there already is an
access road that can easily accommodate this very low level of use there does not
seem to be sufficient justification for the permanent and temporary habitat impacts
plus potential additional operational impacts from adding a second road to the site.
We recommend an alternatives analysis that uses the existing structure to support

r�.
the pipes , or makes the minimal changes necessary to the existing structure to
support the proposed pipe expansion.
In addition the MND should consider the indirect and cumulative impacts of adding
abridde and,the resultant potential for increased traffic to this relatively
undisturbed area.
Excess" impervious cover
It appears that a large amount of the increased impermeable cover is related to
adding a second road that then must allow for vehicles to move around the site
from two locations instead of just one. Eliminating this second roadway should
result in a significant reduction in pavement required.
Increasing the percentage of impervious cover in a watershed is one of the key
contributors to watershed decline. The Agua Hedionda sub -watershed is already
at 32% impervious cover- a level at which a natural watershed cannot maintain
natural functions and is in a state of decline without intervention. (See discussion
of this in CWN Watershed Management (Plan): Increasing impervious cover in this
particularly sensitive area right next to the lagoon will only contribute to the
cumulative decline of this watershed.
- Compliance with HMP and other wetlands protection requirements
While the project does not cause direct impacts to wetlands, there are three
sensitive bird species present in the adjacent wetlands: Blue heron, Elegant tern,
and Brown Pelican; and one upland bird species CA Coastal Gnatcatcher(CCG) .
The BIO mitigation measures properly considered this as occupied CSS. But the
BIO measures do not adequately address all of the other species specific
requirements included in the HMP. HMP Table 9 includes specific species level
conservation goals for the Brown Pelican and Elegant Tern at Agua Hedionda
Lagoon. The avoidance/minimization measures for the Brown Pelican include
- "Manage preserve areas to minimize contamination by pesticides, oil and
other pollutants;
- reduce disturbance at important foraging and roosting areas,
- and maintain lagoon hydrology and water quality ( e.g. 100 foot setback
from existing wetland habitats."
Additional requirements for the Elegant Tern include:
"Manage preserved areas to minimize edge effects, control non-native
plants, maintain hydrology and water quality, protect habitats from physical
disturbances, control predators, and maintain vegetation to provide optimal
conditions for breeding.
u�r
- Where opportunities arise, restore and enhance habitat in preserved areas;
- Habitat adjacent to the lagoons will be preserved to the maximum extent
possible.":
The MND needs to specifically address how the proposed plan is in. compliance
with all of these avoidance measures- particularly the 100' setback and
preserving habitat adjacent to the lagoons to the maximum extent possible. This
facility has operated for years with a single road. Much more justification is
needed to support adding a second road and more paving in this highly sensitive
area.
Project not in compliance with coastal zone requirements
Item 7-8 of the HMP says that impacts to CSS "shall be located to minimize
impacts to Coastal sage Scrub and maximize protection of the Coastal California
gnatcatcher and its habitat." Clearly there are alternatives to reduce the impacts
to CSS in the coastal zone- like realigning the bridge up to the already disturbed
area, reducing the size of the bridge or eliminating expansion of the bridge
completely.
- Mitigation as proposed does not best preserve the habitat functions
The mitigation proposed retains the mitigation in the coastal zone and near the
area of impact, at a 2:1 ratio. This meets the letter of the requirements- but fails
to meet the intent. Replacing one small isolated patch of CSS with another small
isolated patch does not best serve the goal of protecting coastal resources. The
NNG mitigation is proposed at the Lake Calavera area. This is consistent with the
HMP, but provides no value to the area of impact along Agua Hedionda Lagoon.
Several opportunities for buffer improvement and habitat restoration along the
lagoon were identified in the AH Watershed Management Plan. The city should
evaluate these areas for mitigation for impacts around the lagoon as a first choice -
before going miles away. Clearly it costs less to use the Lake Calavera area- but
it provides no direct benefit to the lagoon- and that is the area that is being
impacted.
Potential indirect impacts on future smart growth projects
The project is intended to provide sufficient capacity to meet build out of the city -
based on the existing approved General Plan. While the city has a Growth
Management Plan in place that sets a lirnit on growth by quadrant — the exact
nature of this growth and where it could be located has some flexibility. Has this
project adequately sized this facility so that it can accommodate future growth -
including that included on the SANDAG smart growth map ? Sizing it to meet
these anticipated changes will assure that these impacts do not occur again in a
few years.
- Sewage spill warning systems
The recent sewer spill that effected Buena Vista Lagoon was made worse by not
being detected in a timely manner. One of the recommendations we made to the
RWQCB in response to this was to include better pipeline/sewer system failure
warning systems. The MND mentioned a single daily site inspection. Please
describe how this project will address pipeline monitoring including sensors and
turn-offs that would limit the damage from any future pipeline or other system
failures.
We look forward to working with you to assure that all of these issues are
addressed before this project moves forward.
Thank you for considering these comments.
Sincerely,
Diane Nygaard.

Dear Ms. Nygaard`.
Thank you for submitting comments on the Draft Mitigated Negative Declaration (MND) for the
Agua Hedionda Sewer Lift Station and Gravity and Force Main project (SCH No. 2010081053).
This response letter was written to address your comment letter dated August 31, 2010. Each
comment from your letter is shown in italics, followed by the City's response.
Comment: Bridge to .provide second. roadwav access. Currently there is a very simple
structure to support pipes. The project proposes to replace this with a much more substantial
bridge that would accommodate vehicles and thereby provide a secondary road access to the
site. While this new bridge would remove support structures from the waterway, it would cause
significant direct habitat impacts. We think it could also cause additional indirect impacts
associated with vehicle traffic and other use of this bridge in an area that previously would be
very undisturbed.
The MND indicates that only one daily vehicle trip to the site is anticipated for inspection and
periodic additional trips for maintenance. -Since there already is an access road that can easily

- -permanent -and: temporary -habitat _impac-ts = plug potential_ additional. operational -:impacts from
adding a second road to the site. We recommend an, alternatives analysis that uses the existing
structure to support the pipes, or makes the minimal changes necessary to the existing structure
to support the proposed pipe expansion.
Response: The existing trestle bridge structure has been analyzed as an alternative to the
installation of the new proposed bridge. From a functional standpoint, the structure is aged and
in generally poor condition from decades of weathering. Efficient repair and upgrade of this
existing bridge for long-term pipe support would necessitate the replacement of the deteriorated
support pilings and horizontal members, and as such, would effectively result in replacement of
all bridge materials. Furthermore, the existing sewer pipe is 42-inches in diameter, and it will be
replaced by a 54-inch diameter pipe.

Utilizing the existing 42-inch pipeline alignment would require construction of a temporary by-
pass sewer pipe and structure to cross the lagoon during the implementation of structural
improvements of the existing sewer bridge. The direct impacts to the surrounding area would.
effectively be identical to the proposed new structure. Furthermore, the existing bridge design is
inadequate to hold the additional weight associated with the larger pipe. As mentioned in the
MND, this larger pipe is necessaryin order to provide the necessary capacity for future
anticipated build -out demand of the service area, as identified in the City of Carlsbad Sewer
Master Plan, dated March 2003.
In addition, from an environmental standpoint, the existing bridge structure contains eight (8)
narrow bridge support/pilings which presently are located within the lagoon. This channel is the
most. environmentally sensitive segment of the project construction area. These supportpilings
-- -are 14=inches-in-d.iamete.r_f-and-.set_i.nto_con.cre-te_sit.uated_.as de.ep-as _appr_oxim.atel}r20-feet
below the mud line on the bottom of the channel The proposed new replacement bridge will be
supported by concrete bridge abutments located on dry land on each side of the channel. With
a horizontal clear span of 140-feet, the new bridge will span the entire width of the channel
Therefore, the existing in -channel obstructions will be eliminated by the full -span bridge. This
design will have a positive effect on the hydrology and biology of the channel. The suggested
alternative of repairing the existing weathered pilings would require significant construction and
replacement work within the channel waters and on the channel bottom, including pile driving
and/or excavation. The new bridge renders this work in the channel unnecessary.
The inclusion of the maintenance vehicle access drive in the bridge design does not result in
any additional biological impacts. The accommodation of maintenance access across the
bridge will result in greater efficiency of maintenance, and swifter response to any emergency
that may arise at the lift station, and does not result in substantive expansion of the bridge
width. In addition, multi -use of the bridge structure is a sensible and cost effective use of this
public utility structure.
Comment: In addition the MND should consider the .indirect and cumulative impacts of adding
a bridge and the resultant potential for increased traffic to this relatively undisturbed area.
Response: No significant increase in traffic to the relatively undisturbed lift station area will
result from the inclusion of a gated and locked maintenance drive across the proposed channel
bridge. Vehicular trips across this bridge are estimated at 2 average daily trips (ADT's). This 2
ADT's estimate is based on the anticipated per day maintenance vehicle visit to and from the lift
station. Such level of ADT is considered de minimus for CEQA purposes, and will not result in
any significant direct, indirect or cumulative traffic impacts. Primary access will continue to go
through the Encina Power Plant site.
Comment: Excess impervious cover. It appears that a large amount of the increased
impermeable cover is related to adding a second road that then must allow for vehicles to move
around the site from two locations instead of just one. Eliminating this second roadway should
result in a significant reduction in pavement required.
Increasing the percentage of impervious cover in a watershed is one of the key contributors to
watershed decline. The Agua Hedionda sub -watershed is already at 32% impervious cover- a
level at which a natural watershed cannot maintain natural functions and is in a state of decline
without intervention. (See discussion of this in CWN Watershed Management Plan). increasing

impervious cover in this particularly sensitive area right next to the lagoon will only contribute to
the cumulative decline of this watershed.
Response: The proposed lift station and related driveways will increase impervious cover from
20,434 square feet (existing lift station is 8,670 square feet and the existing overflow basin is
11,764 square feet) to 55,390 square feet. However, as indicated in the MND, the new lift
station will include a number of site design water quality Best Management Practices (BMPs)
which will serve to ensure that this increase in impervious cover will not negatively impact the
watershed. These BMPs include treating runoff from the site through: 1) routing drainage into
pervious vegetated or rock swales; 2) designing with catch basin structures with filter media
inserts; 3) inclusion of pervious ground surface materials; 4) situating an infiltration basin at the
low end of the site to treat project runoff; and 5) hydroseeding the area where the overflow basin
is with a native seed mixture.
All of these features serve to allow the natural filtering ability of the soil to remove pollutants
from runoff prior to exiting the project area. The existing facility does not have these runoff
treatment features. Some increase in impervious area will result from the proposed project;
however, the project design incorporates sufficient BMPs which will mitigate any potential- for
increase in impacts on the natural functions of the lagoon and watershed. Therefore, the
implementation of the project will not cause a decline to the watershed.
Comment: Compliance with HMP and other wetlands protection requirements. While the
project does not cause direct impacts to wetlands, there are three sensitive bird species present
in the adjacent wetlands; Blue Heron, Elegant Tern, and Brown Pelican; and one upland bird
species CA Coastal Gnatcatcher (CCG). The BIO mitigation measures properly considered this
as occupied CSS. But the B10 measures do not adequately address all of the other species
specific requirements included in the HMP. HMP Table 9 includes specific species level
conservation goals for the Brown Pelican and elegant Tern at Agua Hedionda Lagoon. The
avoidance/minimization measures for the Brown Pelican include:
Manage preserved areas to minimize contamination by pesticides, oil and other
pollutants; reduce disturbance at important foraging and roosting areas, and maintain
lagoon hydrology and water quality (e.g. 100 foot setback from existing wetlands
habitats).
Additional requirements for the Elegant Tern include:
Manage preserved areas to minimize edge effects, control non-native plants, maintain
hydrology and water quality, protect habitats from physical disturbances, control
predators, and maintain vegetation to provide optimal conditions for breeding.
Where opportunities arise, restore and enhance habitat in preserved areas;
Habitat adjacent to the lagoons will be preserved to the maximum extent possible.
The MND needs to specifically address how the proposed plan is in compliance with all of these
avoidance measures - particularly the 100' setback and preserving habitat adjacent to the
lagoons to the maximum extent possible. This facility has operated for years with a single road.
Much more justification is needed to support adding, a second road and more paving in this
highly sensitive area.

Response: The proposed project does not result in any direct impacts to wetland habitats. As
such, the HMP does not require that avoidance/minimization measures of Table 9 be
specifically addressed because the habitat is avoided. However, the MND does conclude on
page 42 that the project may have the potential for indirect impacts on nesting or breeding birds
in the adjacent Agua Hedionda Lagoon wetland habitat because of impacts resulting from
temporary, construction -related noise. Listed birds not identified on or near the site, but
potentially impacted by indirect impacts, include the birds you listed.
These potential noise impacts would be considered impacting only if the noise created a
disruption of nesting activities, and thus only during the bird nesting/breeding season, generally
from January 15 to September 15 of any year. Thus, the MND concludes that if project
construction is contemplated during this time, the project would need to implement Mitigation
---Measure BIO-5, which will ensure that noise impacts do not adversely impact nesting birds.
In addition to avoiding direct impacts to the wetlands, the project minimizes edge effects on the
wetlands as required by the HMP. Project features which have been included to minimize the
edge effects are: 1) fencing around the lift station site; 2) water quality BMPs; and 3)
revegetation of upland habitats on or near the impact location. These project features.. are
consistent with the recommendation of the HMP.
Furthermore, the project will maintain a 100-foot setback in all cases except for the proposed
bridge across the Agua Hedionda Lagoon channel. This bridge structure however, is "location
dependent" because no feasible alternative location exists for the bridge and by definition the
sewer line must cross the channel wetlands. Further, the bridge will replace an existing
deteriorating pipe -support bridge which will be removed. Discussions -of -these aspects of the
project are included in the MND.
Justification for the maintenance road and increase in paving has. been addressed in responses
--above. With -the -design of the project -and -with the inclusion of the Biology Mitigation Measures
listed in the MND, the indirect project impacts to federal and/or state listed species will be fully
mitigated.
Comment: Proiect not in comoliance with coastal zone requirements. Item 7-8 of the HMP
says that impacts to CSS shall be located to minimize impact to Coastal Sage Scrub and
maximize protection of the Coastal California gnatcatcher and its habitat. Clearly there are
alternatives to reduce the impacts to CSS in the coastal zone — like realigning the bridge up to
the already disturbed area, reducing the size of the bridge or eliminating the expansion of the
bridge completely.
Response: The project has been designed to execute the project goals while minimizing
impacts on CSS and other sensitive habitats. Total impacts to CSS are limited to 0.05 acres of
permanent and 0.04 acres of temporary impacts. As indicated in the MND, these minimal
impacts will be fully mitigated. Realignment of the 54-inch sewer trunk main in order to avoid a
very small area of CSS located at the south bridge abutment would result in unnecessary
turning/angling of the line. This turning/angling would not only result in increased costs devoted
to longer bridge construction, etc., but also would add interior surface friction and resulting
operational and maintenance costs. Reducing the size of the bridge in the same proposed
location will not avoid this small area of CSS, and eliminating the bridge is not feasible. Using
the existing trestle bridge is not recommended for the reasons stated above.

Comment: Mitigation as proposed does not best preserve the habitat functions. The mitigation
proposed retains the mitigation in the coastal zone and near the area of impact, at a 2:1 ratio.
This meets the letter of the requirements — but fails to meet the intent. Replacing one small
isolated patch of CSS with another small isolated patch does not best serve the goal of
protecting coastal resources. The NNG mitigation is proposed at the Lake Calavera area. This
is consistent with the HMP, but provides no value to the area of impact along Agua Hedionda
Lagoon. Several opportunities for buffer improvement and habitat restoration along the lagoon
were identified in the AH Watershed Management Plan. The city should evaluate these areas
for mitigation for impacts around the lagoon as a first choice — before going miles away. Clearly
it costs less to use the Lake Calavera area — but it provides no direct benefit to the -lagoon — and
that is the area that is being impacted.
Response: One of the key objectives of the HMP was permitting for city public facility projects
mandated by the city's Growth Management Plan. Both the HMP and the HMP implementing
Agreement between the USFWS, CDFG and the City established the Lake Calavera Mitigation
Parcel for biological mitigation of public works projects that the City undertakes. Appendix B-3
of the HMP specifically lists the Agua Hedionda Sewer Lift Station project as_a project to be
covered by Lake Calavera mitigation credits. Not only is it a cost-effective means by which
biological mitigation can be achieved, it is appropriate for the city to mitigate at Lake Calavera
because a fundamental objective of the HMP is to build the citywide preserve system by
combining small mitigation requirements into a larger, contiguous area.
Comment: Potential indirect impacts on future smart growth projects. The project is intended
to provide sufficient_ capacity to meet buildout of the city — based on the existing approved
General Plan. While the city has a Growth Management Plan in, -place that sets a limit on
growth by. quadrant — the exact nature of this growth and where it could be located has some
flexibility. Has this project adequately sized this facility so that it can accommodate future
growth — including that included on the SANDAG smart growth map? Sizing it to meet these
anticipated changes will assure that these impacts do not occur again in a few years.
Response: The project has been designed to accommodate future sewer demand at buildout
as anticipated by the approved General Plans for cities within the service area with an additional
allowance for wet weather flows. It is anticipated that future capacity will become available as
_.. ist_a and Carlsbad reduce wet weathernflows into the system. Additionally, wastewater flows
per capita are anticipated to decline in future years as customers continue to conserve water
and implement water saving devices and appliances.
Comment: Sewage spill warning systems. The recent sewer spill that affected Buena Vista
Lagoon. was made worse by not being detected in a timely manner. One of the
recommendations we made to the RWQCB in response to this was to include better
pipeline/sewer system failure warning systems. The N1ND mentioned a single daily site
inspection. Please describe how this project will address pipeline monitoring including sensors
and turn-offs that would limit the damage from any future pipeline or other system failures.
Response: The lift station is equipped with multiple redundant features in terms of emergency
back-up power. it is designed with two independent electrical circuits (primary and secondary)
plus a generator, for a total of three independent power sources and will include an automatic
standby transfer switch in the event of catastrophic electric failure. In the event of full regional

blackout, emergency power will be provided by a built-in, onsite diesel fuel generator. Under
such emergency conditions, the generator will provide power to all lift station facilities. The
generator has the capacity to store enough fuel for 24 hours of operation.
In addition, the lift station includes two independent pumping elements providing mechanical
redundancy, ensuring that equipment failures do not result in sewage spills. In the event that a
total mechanical failure occurs on either side, the station remains operable without
consequences under peak dry weather flow conditions. Furthermore, the station is designed
with alarms to alert officials to any electrical problem and to enact the contingency plan to
reduce flow into the station (upstream lift stations contain storage volume) if an emergency were
to occur. The upstream pipe also contains a significant amount of passive storage capacity,
which can gradually fill up to allow the time necessary to resolve a problem, should it occur.

RECOMMENDS APPROVAL of the AGUA HEDIONDA SEWER LIFT
STATION, FORCE MAIN AND GRAVITY SEWER REPLACEMENT —
PDP 00-02(C), based on the following findings and subject to the following
conditions:
Findings:
1. The Precise Development Plan PDP 00-02(C) is consistent with the intent and purpose
of the Public Utilities (P-U) Zone, Section 21.36.010 (1) of the Carlsbad Municipal Code,

to provide a Precise Development Plan that is compatible with the General Plan and
surrounding developments, in that (1) existing and permitted land uses of the
proposed Precise Development Plan are consistent with and/or implement the
objectives of the Public Utilities (U) General Plan designation; (2) the Precise
Development Plan, through development standards and review procedures, is
compatible with surrounding developments; (3) the Precise Development Plan
planning area is adequately buffered from surrounding, more sensitive uses (e.g.,
residences and businesses) by open space, other utility uses, and transportation
corridors and through development standards, including setbacks, of the proposed
Precise Development Plan. Furthermore, the proposed pipe support bridge will be
constructed to allow for the future Coastal Rail Trail, a separate, future project in
this area, which will enhance the public's use of open space areas and facilitate
public access in the Agua Hedionda Lagoon area.
2. The Precise Development Plan PDP 00-02(C) is consistent with the intent and purpose
of the Public Utilities (P-U) Zone, 21.36.010 (2) of the Carlsbad Municipal Code to
provide a Precise Development Plan that has given due regard to environmental factors,
in that the proposal has been reviewed concurrently with the processing of the
Mitigated Negative Declaration and Mitigation Monitoring and Reporting Program
in compliance with the provisions _ of the California Environmental Quality Act
(CEQA). Furthermore, the existing sewer lift station, which was constructed in
1964, is under -sized, outdated and in some areas nearing the end of their useful life,
and could endanger the lagoon and nearby sensitive habitat if a sewer leak or pump
failures should occur.
3. Precise Development Plan PDP 00-02(C) is consistent with the intent and purpose of
the Public Utilities (P-U) Zone, 21.36.010 (3) of the Carlsbad Municipal Code to provide
a Precise Development Plan that provides for necessary public improvements, in that the
proposed project does not include residential, commercial or industrial land uses,
and does not include any components that would result in an increase in population
or any public facility or infrastructure demand. Project operations will not result in
any increased traffic and will thus not result in any substantial deterioration of the
public roadway system, nor generate a need for other governmental services, such
as libraries or emergency services. The existing sewer facilities do not have sufficient
capacity to convey future projected build -out wastewater flows of the urbanized
service area. The proposed project is designed of a size adequate to convey the
future anticipated build -out demand of the service area. Furthermore, as part of the
approval of PDP 00-02 (B) and RP 05-12(A) for the EPS and CSDP, appropriate
public improvement conditions were imposed along and within the PDP and SP 144.
As noted above the SLS has negligible if any Growth Management impacts and does
not warrant improvements to public facilities.
4. The Precise Development Plan PDP 00-02(C) permits the SLS that is identified as a
permitted use in the P-U Zone by Municipal Code Section 21.36.020 (4)(c) and that
incorporates design, location, and operation characteristics that ensure compliance
with the intent and purpose of the P-U Zone. Furthermore, PDP 00-02(C) sets forth
the standards of development :for the SLS.

5. The Precise Development Plan PDP 00-02(C) is consistent with the General Plan in
that:
a. It provides regulations and standards for uses that are appropriate uses for the
General Plan Public Utilities ("U") land use designation, the designation applied to
the SPS.
b. The General Plan Land Use Element notes that the U land use designation is applied
to existing areas, such as the EPS, that are being used for public or quasi -public
functions.
c. The proposed SLS is needed to ensure adequate provision of sewer service into the
future and will protect the quality of the lagoon and sensitive habitat in the area by
locating the SLS further to the east, installing modern equipment, and replacing the
fragile wood trestle that currently encroaches in the lagoon. These elements are
consistent with Land Use Element Growth 1Vlanagement and Public Facilities Goal
A.1, which states, "A City which ensures the timely provision of adequate public
facilities and services to preserve the quality of life of residents."
d. The proposed SLS will replace an existing sewer lift station that is old and not
adequately sized to accommodate planned growth per the existing Carlsbad and
Vista General Plans. In addition, the project would result in more efficient and,
reliable wastewater transport to the EWPCF. The project is consistent with the
Land Use Element Growth Management and Public Facilities Goal A.2, which
states, "A City which maintains a system of public facilities adequate for the
projected population" and Goal A.3, which states, "A City that responsibly deals
with the disposal of solid and liquid waste."
e. The proposed SLS will be constructed within the existing hillside away from the
lagoon and will not be visible from the south and east, nor will it block lagoon or
ocean views. In addition, to its sensitive site design, both the SLS and the proposed
pipe support bridge use colors and materials that blend with their surroundings.
Furthermore, the proposed pipe support bridge will be constructed to allow for the
future Coastal Rail Trail. These elements are consistent with Land Use Element
Environmental Implementing Policies and Action Programs C-5, which states,
"Limit future development adjacent to the lagoons and beach in such a manner so
as to provide to the greatest extent feasible the physical and visual accessibility to
these resources for public use and enjoyment."
f. General Plan Circulation Element Scenic Roadway Policy C.1 requires
implementation of the Carlsbad Scenic Corridor Guidelines. This 1998 document
addresses the appearance of development along the railroad corridor and states
buildings adjacent to the railroad shall be "architecturally articulated" and present
a "pleasant favade." The SLS as well as the pipe support bridge achieve this desired
goal through site and structure design and colors and materials. The SLS, for
example, will be constructed mostly below the surrounding finish grade level to
preserve the natural contours of its hillside setting. Further, the different structures
of the SLS have flat roofs and vary in shape and height to provide articulation.
Finally, as with the proposed pipe support bridge, exterior materials and colors
appropriately blend with their surroundings.
6. The Precise Development Plan PDP 00-02(C) is consistent with Encina Specific Plan
144 in that:

a. It complies with and enhances applicable Specific Plan standards and
requirements adopted over, the years to regulate development at the EPS.
b. I.t documents and maps power plant uses and features, and, since it proposes no
changes to the operation of the EPS, the Precise Development Plan does not
conflict with Specific Plan standards and requirements regarding power station
operations.
c. The proposed amended Encina Specific Plan, SP 144(L), incorporates the land
use designations of the City of Carlsbad General Plan, with which the Precise
Development Plan is consistent. Additionally, SP 144(L) would incorporate by
reference PDP 00-02(C).
7. The Precise Development Plan PDP 00-02(C) is consistent with the goals of the South
Carlsbad Coastal Redevelopment Plan in that:
a. Establishment of the Precise Development Plan and its development and
environmental standards assists in eliminating blight and environmental
deficiencies in the Redevelopment Plan area and ensuring quality site design. In
that the proposed project will allow for the dismantling and elimination of the
existing lift station structure, over flow basin, and trestle -style wood bridge(s),
including the removal of the pilings that are located in the lagoon channel, which
would be considered a beneficial impact to the lagoon and visual character of the
site.
b. Locating the SLS as proposed, on the northern edge of the EPS and between the
railroad and freeway, minimizes constraints on any future use of the EPS.
Furthermore, the proposed project will be constructed primarily underground
and will not be visible as viewed from the east and south by motorists,
passengers and pedestrians in the area.
c. As mentioned previously, the proposed pipe support bridge will be constructed
to allow for the future Coastal Rail Trail, a separate, future project in this area,
which will enhance recreational activities where none exist through this area.
d. The project also includes the installation of a 12-inch recycled water line, which
will run the length of the project. The recycled water line will improve the
reliability and water quality of the City's recycled water system and will provide
adjacent commercial, industrial and office sites a reliable water supply_ for
landscaping as an alternative to using potable water that is in short supply.
e. The existing sewer lift station and pipelines, which were constructed in 1964 and
rehabilitated in 1989, are under -sized, outdated, and in some areas nearing the
end of their useful life. These facilities also do not have sufficient capacity to
convey future projected buildout wastewater flows of the urbanized service
areas of the cities of Carlsbad and Vista. The proposed project is designed of a
size adequate to convey the future anticipated buildout demand for the two cities
and features modern components to improve reliability and functionality.
8. The Precise Development Plan PDP 00-02(C) is in conformance with the Coastal Act,
Agua Hedionda Land Use Plan, Mello II segment, and Coastal Resource Protection
Overlay Zone in that it has been reviewed for consistency with relevant coastal
policies including land use, habitat protection, grading and drainage, stormwater
management, recreation, shoreline access, and visual resources. In particular, the

Precise Development Plan achieves consistency with Land Use Plan policies as
follows:
a. The Precise Development Plan regulates uses that are consistent with those land
uses shown on the Plan's Land Use Map (Policy 1.1).
b. The Precise Development Plan is subject to, and incorporates as a regulating
document, the MMRP for the project's MND, which provides mitigation to
ensure consistency with Land Use Plan policies regarding environmentally
sensitive habitats, geology, water quality, and other environmental resources.
c. The project avoids impacts to marine resources as the proposed bridge structure
will completely span the entire channel width. Furthermore, the existing trestle
bridge structure which supports the existing 42-inch sewer pipe will be removed
and the eight (8) narrow bridge support pilings which presently sequence across
and into the bottom of the Agua Hedionda Lagoon channel will also be removed.
In addition, the existing trestle bridge structure which supports the 12-inch high
pressure gas line may be relocated to the proposed pipe support bridge, allowing
the trestle bridge, including the four (4) bridge support pilings, to be removed.
d. The project will avoid onsite erosion as a result of the use of silt fences, sandbags
and straw mulch rolls being placed around excavated trench spoils during the
construction period. Furthermore, all storm drains and natural drainages
situated downstream from the construction will be protected by linear sediment
barriers or similar erosion control devices. Following construction, the project
also will feature permanent source control and treatment control features in
order to protect any adjacent downstream waters, such as Agua Hedionda
Lagoon, from potential pollution.
e. Development permitted by :Precise Development Plan PDP 00-02(C) is consistent
with the development standards, such as building height, of the Agua Hedionda
Land Use Plan.
f. The proposed bridge structure will be constructed to allow for the future
Coastal Rail Trail.
9. The approval of Precise Development Plan PDP 00-02(C) fulfills the requirement of
Municipal Code Section 21.36.030, which in part states that "no building permit ,or
other entitlement for any use in the P-U zone shall be issued until a precise
development plan has been approved for the property."
10. As conditioned, the project is consistent with the City's Landscape Manual (Carlsbad
Municipal Code Section 14.28.020 and Landscape Manual Section I 13).
11. The Planning Commission has reviewed each of the exactions imposed on the Developer
contained in this resolution, and hereby finds, in this case, that the exactions are imposed
to mitigate impacts caused by or reasonably related to the project, and the extent and the
degree of the exaction is in rough proportionality to the impact caused by the project.
Conditions:
Note: Unless otherwise specified herein, all conditions shall be satisfied prior to the issuance of
a Notice to Proceed.

NOW, THEREFORE, BE IT HEREBY RESOLVED by the Planning
Commission of the City of Carlsbad as follows:
A) That the foregoing recitations are true and correct.
B) That based on the evidence presented at the public hearing, the Commission
RECOMMENDS APPROVAL of the Specific Plan Amendment, SP 144(L), for
the AGUA HEDIONDA SEWER LIFT STATION, FORCE MAIN AND
GRAVITY SEWER REPLACEMENT PROJECT based on the following
findings and subject to the following conditions:
Findings•
The proposed development as described by the Specific Plan SP-144(L) is consistent
with the provisions of the General Plan in that the development proposed for the
Agua Hedionda Sewer Lift Station, Force Main and Gravity Sewer Replacement
project, as described in the Mitigated Negative Declaration, is consistent with the
applicable General Plan land use designations and policies. The proposed
development consists of a sewer lift station, pipe support bridge and pipelines
(sewer, recycled water, and potable water), which complies with General Plan land
use designations and goals to ensure adequate public facilities and economic growth
to sustain Carlsbad's quality of life. Further, the Encina Specific Plan 144 provides
all specific plan standards in a single, comprehensive document, which helps
facilitate the General Plan goal to ensure the timely provision of adequate public
facilities and services to preserve the quality of life of residents.
2. SP 144(L) would not be detrimental to the public interest, health, safety, convenience, or
welfare of the City in that it: 1) does not propose any changes to existing general plan
land use or zoning designations; 2) does not alter any condition set forth by a
previously approved specific plan amendment to regulate the Encina Power Station;
3) authorizes only development proposed by the Agua Hedionda Sewer Lift Station,
Force Main and Gravity Sewer Replacement project, for which a Mitigated
Negative Declaration (MND) has been prepared, and 4) provides a single,
comprehensive document that contains all. pertaining rules and regulations set forth
PC RESO NO. 6755 -3-
I by previously approved specific plan amendments and the contents required by
2 Government Code Section 65453.
3 3. The proposed specific plan amendment is consistent with the Local Coastal
Program in that it does not change any land use designations of the Agua Hedionda
4 Land Use Plan, authorizes development (the Agua Hedionda Sewer Lift Station,
5 Force Main and Gravity Sewer Replacement project) consistent with the Land Use
Plan, and provides the pipe support bridge over the Agua Hedionda Lagoon that is
6 being designed to accommodate the Coastal Rail Trail, a separate, future project in
this area, which will allow pedestrians and bicyclists recreational opportunities that
7 further Coastal Act policies regarding public access and use of area features, such as
8 Agua Hedionda Lagoon.
4. Specific Plan 144(L) provides assurances that all necessary public facilities can be
9 provided concurrent with need and adequate provisions have been provided .to implement
10 those portions of the capital improvement program applicable to the subject property in
that the proposed project does not include residential, commercial or industrial land
11 uses, and does not include any components that would result in an increase in
population or any public facility or infrastructure demand. Furth ermore,__project

WHEREAS, the Planning Commission did on February 2, 2011, hold a duly
noticed public hearing as prescribed by law to consider said request; and
WHEREAS, at said public hearing, upon hearing and considering all testimony
and arguments, if any, of all persons desiring to be heard, said Commission considered all factors

NOW, THEREFORE, BE IT HEREBY RESOLVED by the Planning
Commission of the City of Carlsbad as follows:
A) That the foregoing recitations are true and correct.
B) That based. on the evidence presented at the public hearing, the Commission
RECOMMENDS APPROVAL of AGUA HEDIONDA SEWER LIFT
STATION, FORCE MAIN AND GRAVITY SEWER REPLACEMENT
PROJECT — RP 10-26, based on the following findings and subject to the
following conditions:
Findings:
1. The City of Carlsbad Planning Commission hereby finds the SLS serves an extraordinary
public purpose to the City of Carlsbad, the redevelopment area, and the citizens of
Carlsbad as demonstrated by the following benefits:
a. Improve reliability and functionality : The existing sewer lift station and
pipelines, which were constructed in 1964 and rehabilitated in 1989, are under-
sized, outdated, and in some areas nearing the end of their useful life. These
facilities also do not have sufficient capacity to convey future projected build -out
wastewater flows of the urbanized service areas of the cities of Carlsbad and
Vista. The proposed project is designed of a size adequate to convey the future
anticipated buildout demand for the two cities, and features modern components
to improve reliability and functionality.
b. Provide a recycled water supply: The project also includes the installation of a
12-inch recycled water line, which will run the length of the project. Eventually,
this line will provide adjacent commercial, industrial and office sites a reliable
water supply for landscaping as an alternative to using potable water that is in
short supply.
c. Facilitate Recreational Opportunities: The pipe support bridge over the lagoon
channel is being constructed to accommodate the Coastal Rail Trail, a separate,

future project in this area, which will enhance recreational activities where none
currently exists.
d. Restore and Enhance the Marine Environment: The SLS will be located further
to the east, will install modern equipment, and will replace the fragile wood
trestle bridge(s) that currently encroaches in the lagoon. The trestle bridge(s),
including the removal of the pilings that are located in the lagoon channel, would
be considered a beneficial impact to the lagoon. Furthermore, the new pipe
support bridge will span the entire width of the channel and will not impact the
lagoon.
e. Remove Blight: The proposed project will allow for the dismantling and
elimination of the existing; lift station structure and over flow basin that was
constructed in 1964. The new SLS will be constructed primarily underground
and will not be visible as viewed from the east and south by motorists,
passengers and pedestrians in the area. The structures will be stained earth -tone
colors to blend in with the surrounding area. Furthermore, although adjacent to
the SCCRA plan boundaries, the existing trestle -style wood bridge(s) will be
removed and replaced with a modern steel bridge with a weathered -.I oot ing
guardrail, which will improve the visual character of the overall area.
2. That the proposed SLS use can be approved because the underlying Public Utilities (P-U)
zoning district requires the approval of an official Precise Development Plan prior to the
approval of building permits for allowed uses, and PDP 00-02(C), processed and
approved concurrently with RP 10-26, serves as the code -mandated regulatory document
for the subject property.
3. As demonstrated in Finding 1 above, the Project complies with several SCCRA Plan
goals, which are listed in Section IV (400) of the Plan that seek to increase coastal
recreation opportunities, eliminate blight and environmental deficiencies, and strengthen
the economic base of the project area through reliable, modern infrastructure.
Furthermore, the Project also complies with the following Plan goal:
a. Implement performance criteria to ensure quality site design and environmental
standards to provide unity and integrity to the entire Redevelopment Plan area.
The SLS complies with this goal by exhibiting a quality design and color (earth -
tones) that is sensitive to its environment and non -utility surroundings. As a
regulatory document, the Precise Development Plan establishes development
standards and review procedures for the EPS and the SLS. Further, the Project
has been reviewed concurrently with the processing of the MND, compliant with
the provisions of the California Environmental Quality Act (CEQA).
4. The Project is consistent with the; General "Plan in that it implements goals and policies
of the Land Use Element, as demonstrated by the following:
a. The proposed SLS is needed to ensure adequate provision of sewer service into
the future and will protect the quality of the lagoon and sensitive habitat in the
area by locating the SLS further to the east, using modern equipment, and
replacing the fragile wood trestle bridge(s) that currently encroaches in the

lagoon. These elements ,are consistent with Land Use Element Growth
Management and Public Facilities Goal A.1, which states, "A City which ensures
the timely provision of adequate public facilities and services to preserve the
quality of life of residents."
b. The proposed SLS will replace an existing sewer lift station that is old and not
adequately sized to accommodate planned growth per the existing Carlsbad and
Vista General Plans. In addition, the project would result in more efficient and
reliable wastewater transport to the EWPCF. The project is consistent with the
Land Use Element Growth Management and Public Facilities Goal A.2, which
states, "A City which maintains a system of public facilities adequate for the
projected population" and Goal A.3, which states, "A City that responsibly deals
with the disposal of solid and liquid waste."
c. The proposed SLS will be constructed within the existing hillside away from the
lagoon and will not be visible from the south and east, nor will it block lagoon or
ocean views. Furthermore, the proposed pipe support bridge will be constructed
to allow for the Coastal Rail Trail, a separate, future project in the area. These
elements are consistent with Land Use Element Environmental Implementing
Policies and Action Programs C-5, which states, "Limit future development
adjacent to the lagoons and beach in such a manner so as to provide to the
greatest extent feasible the physical and visual accessibility to these resources for
public use and enjoyment."
d. The Project is consistent with the Public Utility (U) land use designation of the
EPS, which permits wastewater treatment facilities. In addition, sewer and
water pipelines are permitted in any land use designation. Further, the SLS
structures will have a flat roof and the buildings are a series of square and
rectangular shapes architecturally articulated to vary building elevations and
facade and will be partially below grade and stained with earth -tones to comply
with the sensitive design objective of Overall Land Use Pattern Policy C.6, which
states, "Review the architecture of buildings with the focus on ensuring the
quality and integrity of design and enhancement of the character of each
neighborhood."
5. The Project is consistent with the Encina Specific Plan 144 in that:
a. It complies with applicable Specific Plan standards and requirements adopted
over the years regarding architectural review, building height, exterior lighting,
and rooftop mechanical equipment.
b. Since the Project proposes no changes to the operation of the EPS, the Project
does not conflict with Specific Plan standards and requirements regarding
power station operations.
c. The proposed amended Encina Specific Plan, SP 144(L), incorporates the land
use designations of the City of Carlsbad General Plan, with which the Project is
consistent. Additionally, SP 144(L) would incorporate by reference PDP 00-
02(C).

6. The Project is in conformance with the Agua Hedionda Land Use Plan and all applicable
policies in that the Project has been reviewed for consistency with relevant coastal
policies including land use, habitat protection, grading and drainage, stormwater
management, recreation, shoreline access, and visual resources. In particular, ,the
Project complies with the Land Use Plan building height limitation of 35 feet.
Furthermore, the Project has been conditioned to obtain a coastal development
permit from the California Coastal Commission.
7. The Project is consistent with the City's adopted Scenic Corridor Guidelines, which
apply to Carlsbad Boulevard and the North County Transit District railroad corridor, in
that the lift station walls on the north and east will be constructed as retaining walls,
and thus hidden from view except for a 5-foot section of the top of the cured -in -
place (CIP) concrete structure. The structure will have a flat roof. As such, the
building is a series of square and rectangular shapes architecturally articulated to
vary building elevations and facade from the view of the rail passengers travelling
through the city. Furthermore, the lift station will be virtually imperceptible to
motorists on Carlsbad Boulevard or on the Carlsbad beach due to the distances
involved, design of structures into the bluff, and material and colors that will blend
in with the surrounding area.
8. The Project is consistent with the Citywide Facilities and Improvements Plan, the Local
Facilities Management Plan for Zones 3 and 22 and all City public facility policies and
ordinances. The City's fire, schools, libraries and parks and, recreation performance
standards were developed assuming population growth occurs through the
construction of additional dwelling units. However, the proposed project does not
include residential land uses, and does not include any components that would result
in an increase in population or any public facility or infrastructure demand that
might result from commercial or other non-residential land uses. Furthermore,
project operations will not result in any increased traffic and will thus not result in
any substantial deterioration of the public roadway system, nor generate a need for
other governmental services, such as emergency services. Replacement of the
existing sewer lift station and force main is designed of a size adequate to convey the
future anticipated build -out demand of the service area.
9. The Planning Commission has reviewed each of the exactions imposed on the Developer
contained in this resolution, and hereby finds, in this case, that the.exactions are imposed
to mitigate impacts caused by or reasonably related to the Project, and the extent and the
degree of the exaction is in rough proportionality to the impact caused by the Project.
10. As conditioned, the Project is consistent with the City's Landscape Manual (Carlsbad
Municipal Code Section 14.28.020 and Landscape Manual Section I B).
Conditions:
Note: Unless otherwise specified herein, all conditions shall be satisfied prior to the issuance of
a Notice to Proceed or commencement of construction, whichever occurs first.

noticed public hearing as prescribed by law to consider said request; and
3
4 WHEREAS, at said public hearing, upon hearing and considering all testimony
5 and arguments, if any, of all persons desiring to be heard, said Commission considered all factors
6 relating to the CDP.
7 NOW, THEREFORE, BE IT HEREBY RESOLVED by the Planning
8 Commission of the City of Carlsbad as follows:
9
A) That the foregoing recitations are true and correct.
10
B) That based on the evidence presented at the . public hearing, the Commission
11 APPROVES AGUA HEDIONDA SEWER LIFT STATION, FORCE MAIN
12 AND GRAVITY SEWER REPLACEMENT CDP 10-17 based on the
-following findings and subject to the following conditions:
13
Findings:
14
15 1. That the proposed development is in conformance with the Mello II Certified Local
Coastal Program and all applicable policies in that the proposed project is consistent
16 with, or otherwise implements, the following Mello II LCP policies:
17 a. Carlsbad LCP Mello II Policy 3-4 Grading and Landscaping Requirements. The
project complies because all work in this area will be within the public right-of-
way way and will be repaved to eliminate the possibility of erosion. Also grading will
19 not occur during the rainy season unless sufficient erosion control measures
have been included in the project construction program.
20 b. Carlsbad LCP Mello II Policy 4-3 Accelerated Soil Erosion. The project complies
because no portion of the project is being developed on steep slopes as identified
21 in the LCP. The project also complies because the project will incorporate
22 BMPs and submit a water quality technical report as specified in the National
Pollutant Discharge Elimination System (NPDES) permit and in the Standard
23 Urban Storm Water Mitigation Plan (SUSMP). In addition, the city will include
requirements in the CDP approval to allow inspection and maintenance of the
24 BMPs, and the project minimizes land disturbance activities during construction
25 (e.g., clearing, grading and cut -and -fill). BMPs are also proposed to treat site
runoff following construction of the SLS.
26 c. Carlsbad LCP Mello II Policy 4-4 Removal of Natural Vegetation. The project
complies because it will not remove any natural vegetation within this segment of
27 the project.
d. Carlsbad LCP Mello II Policy 4-5 Soil Erosion Control Practices. The project
28 complies because onsite erosion will be avoided as a result of the use of silt
fences, sandbags and straw mulch rolls being placed around excavated trench

spoils during the construction period. Furthermore, all storm drains and
natural drainages situated downstream from the construction will be protected
by linear sediment barriers or similar erosion control devices.
e. Carlsbad LCP Mello H Policy 4-6 Sediment Control Practices. The project
complies because sediment control will he provided through the use of silt fences,
sandbags and straw mulch rolls being placed around excavated trench spoils
during the construction period. Furthermore, all storm drains and natural
drainages situated downstream from the construction will be protected by linear.
sediment barriers or similar erosion control devices.
2. The proposal is in conformity with the public access and recreation policies of Chapter 3
of the Coastal Act in that the pipelines will be installed underground and, therefore,
will not impact public access opportunities or recreational resources.
3. That the project is consistent with the provisions of the Coastal Resource Protection
Overlay Zone (Chapter 21.203 of the Zoning Ordinance) in that the project
incorporates measures to adhere to the City's Master Drainage Plan, Grading
Ordinance, Storm Water Ordinance, SUSMP and the Jurisdictional Urban Runoff
Management Program (JURMP) to avoid increased urban runoff, pollutants, and
soil erosion. Further, steep slopes with native vegetation will not be impacted since
pipelines are proposed for city rights -of -way without sensitive habitat, or via
trenchless drilling construction, methods as outlined in the Project's MND. Finally,
the project complies with Coastal Resource Protection Overlay Zone standards
regarding development in liquefaction -prone areas as the project's Mitigation
Monitoring and Reporting Program includes a mitigation measure to address
potential settlement due to seismically -induced liquefaction or later spread.
4. The Planning Commission finds that the project, as conditioned herein, is in
conformance with the Elements of the City's General Plan, based on the facts set forth in
the staff report dated February 2, 2011, including, but not limited to that the
installation of a pipeline is consistent with the Land Use Element of the General
Plan in that the pipeline is allowed in all General Plan land use designations.
5. The project is consistent with the Citywide Facilities and Improvements Plan, the Local
Facilities Management Plan for Zones 3 and 22 and all City public facility policies and
ordinances. The City's fire, schools, libraries and parks and recreation performance
standards were developed assuming population growth occurs through the
construction of additional dwelling units. However, the proposed project does not
include residential, commercial or industrial land uses, and does not include any
components that would result in an increase in population or any public facility or
infrastructure demand. Specifically, the proposed pipelines do not generate any
facility plan improvement requirements or funding.
6. The Planning Commission has reviewed each of the exactions imposed on the Developer
contained in this resolution, and hereby finds, in this case, that the exactions are imposed
to mitigate impacts caused by or reasonably related to the project, and the extent and the
degree of the exaction is in rough proportionality to the impact caused by the project.

10-26/CDP 10-17/HDP 10-05/SUP 10-02/HMP 10-03 based on the following
findings and subject to the following conditions:
Findings•
1. That hillside conditions have been properly identified on the constraints map which show
existing and proposed conditions and slope percentages.
2. That undevelopable areas of the project, i.e., slopes over 40%, have been -properly
identified on the constraints map.
3. That the development proposal is consistent with the intent, purpose, and requirements of
the Hillside Ordinance, Chapter '21.95, in that the SLS structures will be constructed
mostly below the surrounding finish grade level to preserve the natural contours of
the hillside. The large, main lift station will be fitted into the terrain of the site with
exterior walls functioning as soil retaining walls, resulting in the facility being
situated mostly below grade, with only the south and western walls being readily
visible. The low profile structures will have a flat roof with square and rectangular
shapes architecturally articulated to vary building elevations and facades. The
visible portions of the walls of the structures will be accented and shadowed with
textured and geometric patterns and earth tone colors to blend it with the
surrounding hillside. Furthermore, landscaping with native plants will be planted in
front of the buildings to soften the structures appearance.
4. That the proposed development or grading will not occur in the undevelopable portions
of the site pursuant to provisions of Section 21.53.230 of the Carlsbad Municipal Code,
in that the project does include grading of a portion of the slope with an inclination
of greater than 40 percent; however, per Section 21.53.230 this only applies to
natural slopes and not manufactured slopes. The hillside where the SLS will be
constructed was manufactured, which is defined as a man-made slope consisting
wholly or partially of either cut or fill material. As shown on Figure 2 of the
Geotechnical Evaluation Report, prepared by Ninyo & Moore, dated August 3,
2009, the lower pad area of the lift station site and adjacent 2:1 slope are
manufactured from fill material that was likely dredged from the lagoon.
5. That the project design substantially conforms to the intent of the concepts illustrated in
the Hillside Development Guidelines Manual, in that the SLS structures will be
constructed mostly below the surrounding finish grade level to preserve the natural
contours of the hillside. The low profile structures will have a flat roof with square

Commission -of the City of Carlsbad as follows:
A) That the foregoing recitations are true and correct.
B) That based on the evidence presented at the public hearing, the Commission
APPROVES AGUA HEDIONDA SEWER LIFT STATION, FORCE MAIN
AND GRAVITY SEWER REPLACEMENT — SUP 10-02, based on the
following findings and subject to the following conditions:
Findings:
1. The site is reasonably safe from flooding in that the project does not propose any
structures within the 100-year flood hazard area. The project will remove the
existing trestle bridge structure(s), which supports the existing 42-inch sewer pipe
(optionally, the structure supporting the 12-inch high pressure natural gas
transmission line may be removed). Furthermore, the eight bridge support (8)
pilings (possibly two (2) support pilings for the natural gas line), that are located in
the lagoon channel, will also be removed. The removal of the pilings will reduce the
amount of water friction through this narrow channel and allow water to flow faster
through this area should a 100-year flood occur.
2. The project as proposed has been designed to minimize the flood hazard to the habitable
portions of the structure in that no habitable structure is proposed.
3. The proposed project does not create a hazard for adjacent or upstream properties or
structures in that the removal of the bridge pilings will reduce the amount of water
friction and allow the water to flow faster into the outer lagoon and eventually into
the Pacific Ocean, which would prevent any water in the lagoon channel from
creating a hazard to any structures upstream of the bridge structure(s).
4. The proposed project does not create any additional hazard or cause adverse impacts to
downstream properties or structures in that the bridge structure(s) are located over -and
within the lagoon channel that flows into the Pacific Ocean.. The removal of the
bridge pilings and structure(s) will not have an adverse impact on properties or
structures downstream from the bridge structure(s).
5. The proposed project does not reduce the ability of the site to pass or handle a base flood
of 100-year frequency in that the removal of the bridge pilings within the narrow
lagoon channel will better accommodate a 100-year flood through this area.
6. The proposed project taken together with all the other known, proposed, and anticipated
projects will not increase the water surface elevation of the base flood more than one foot
at any point in that the removal of the bridge pilings from the narrow lagoon channel
will improve the flow of the lagoon, thereby increasing floodwater capacity.

1. That the AGUA HEDONDA SEWER LIFT STATION, FORCE MAIN, AND
GRAVITY SEWER REPLACEMENT is not shown in Figure 28 of the approved
HMP as an existing hardline, proposed hardline, proposed standards, core or linkage
area. Instead, the project is in a disturbed area and is identified as a "development
area" in Figure 28; however, there are sensitive vegetation communities within the
Area of Potential Effects (APE) and there will be some temporary and permanent
impacts to the biological resources. Specifically, the area of impact will be for the
installation of the south abutment for the proposed pipe support bridge:
Additionally, the project will benefit adjacent preserved areas as it will remove
bridge support pilings from the channel between the middle and outer basins of
Agua Hedionda Lagoon, both of. which are identified as existing ,hardline
conservation areas.
2. That authorization to take species of concern, through the take of sensitive species (see
Table 4 Project Impacts to Vegetation Communities, which shows permanent and
temporary impacts to vegetation communities provided in' the Preliminary
Biological Assessment report prepared by Planning Systems, dated May 28, 2010
that was prepared for the project) is subject to continuous compliance with all
provisions of the Habitat Management Plan for Natural Communities in the City of
Carlsbad (HMP), the Citywide Incidental Take Permit issued for the HMP, the
Implementing Agreement, the Terms and Conditions of the Incidental Take Permit, and
the Biological Opinion.
3. That authorization to impact sensitive habitats of species of concern is subject to
continuous compliance with all mitigation measures as stated in the Mitigated Negative
Declaration and mitigation Monitoring and Reporting Program and is subject to all
conditions contained in Planning Commission Resolutions No. 6753, 6754, 6755, 6756,
6757, 6758 and 6759 for those other approvals, including but not limited to recordation
of conservation easements over all conserved areas and management and monitoring in
perpetuity by a qualified conservation entity.
4. That authorization to impact sensitive habitats and take of species of concern is subject to
continuous compliance with the provisions of Volumes I, II and III of the Multiple
Habitat Conservation Program and the , Final Environmental Impact
Statement/Environmental Impact Report for Threatened and Endangered Species Due to
Urban Growth within the Multiple Habitat Conservation Program Planning Area (SCH
No. 93121073).
5. That all impacts to habitat and all take of species will be incidental to otherwise lawful
activities related to construction and operation of the AGUA HEDONDA SEWER
LIFT STATION, FORCE MAIN, AND GRAVITY SEWER REPLACEMENT
proj ect.
6. That the project design as approved by the City of Carlsbad has avoided and minimized
impacts to wildlife habitat and species of concern to the maximum extent practicable.
Specifically; most of the impacts are temporary construction impacts to disturbed
PC RESO NO. 6760 _;_
I and developed lands. Furthermore, the project avoids impacts to sensitive habitats,
2 with the exception of minor slivers of Diego Coastal Sage Scrub (DOSS). The DCSS
is surrounded by a highly urbanized environment, and thus the minor slivers are
3 not rare habitat, nor are they especially valuable to the ecosystem which has already
been largely degraded by urbanization, industrialization and the adjacent railroad.
4 As a result of these factors, the project does not impact Environmentally Sensitive
5 Habitat Area (ESHA), a term applicable to properties in the Coastal Zone (as
defined in Coastal Act Section 30107.5) that contain rare or especially valuable
6 plant or animal life or their habitats that could easily be disturbed by human
activities and developments. Notwithstanding that the project will not impact
7 ESHA, it will mitigate for the 0.09 acres of sensitive biological habitats that will be
8 impacted through compliance with the mitigation measures identified in the
Mitigation, Monitoring and Reporting Program (MMRP).
9
7. That adequate funding has been provided to address changed circumstances and adaptive
10 management needs that may be reasonably anticipated in the future, consistent with the
HMP Implementing Agreement.
11
12 8. That the authorization to impact sensitive habitats and incidental take of species of
concern as a result of the project will not appreciably reduce the likelihood of survival
13 and recovery of the species in the wild due to compliance with all of the above stated
requirements, as well as ongoing monitoring and reporting to the wildlife agencies and
14 the public.
15 9 That the Planning Director is authorized to sign the Take Permit.
16
10. The Planning Commission hereby finds that all development in Carlsbad benefits from
17 the Habitat Management Plan, which is a comprehensive conservation plan and
implementation program that will facilitate the preservation of biological diversity and
18 provide for effective protection and conservation of wildlife and plant species while
19 continuing to allow compatible development in accordance with Carlsbad's Growth
Management Plan. Preservation of wildlife habitats and sensitive species is required by
20 the Open Space and Conservation Element of the City's General Plan which provides for
the realization of the social, economic, aesthetic and environmental benefits from the
21 preservation of open space within an increasingly urban environment. Moreover, each
22 new development will contribute to the need for additional regional infrastructure that, in
turn, will adversely impact species and habitats. The In -Lieu Mitigation Fee imposed on
23 all new development within the City is essential to fund implementation of the City's
Habitat Management Plan.

Conditions:
25
26 1. If any of the following conditions fail to occur; or if they are, by their terms, to be
implemented and maintained over time, if any of such conditions fail to be so
27 implemented and maintained according to their terms, the City shall have the right to
revoke or modify all approvals herein granted; deny or further condition issuance of all

analysis for this project. Mitigation Measures are included to require debiting the
appropriate acreage from the Lake Calavera Mitigation Parcel at the ratios
indicated in Table 4 of the MMRP under Biological Resources, except that
Conservation Standards 7-8 and 7-9 (p. D-115) of the HMP require that Diegan
coastal sage scrub mitigation acreage must include a minimum 1:1 creation
component (minimum of 0.05 acre creation). Therefore, project mitigation for
DCSS will include a minimum of 0.05 acres of credit debiting from the Lake
Calavera Mitigation Parcel, and also an additional 0.09 acre of revegetation
(creation) of DCSS on or near the impact location. The 0.09 acres of revegetation
(creation) of DCSS is expected to occur within and around the eastern half of the
demolished, filled -in existing lift station overflow basin, but could occur in a
different location in the area.

IL INTRODUCTION
The proposed project involves the installation of a sewer trunk line in a north -south direction, a
mostly underground, sensitively designed SLS (50 mgd capacity), a modern, attractive sewer
support bridge (140-foot weathered steel span), pipeline improvements on the Vista/Carlsbad
Sewer Interceptor System, specifically segments VC11, VC12, VC13, VC14, and VC15, and
associated sewer force main and gravity piping, including a 6-inch potable water line and a 12-
inch recycled water line. These sewer segments are part of a regional sewage collection program
which receives sewage flow from the cities of Carlsbad and Vista and are jointly owned by the
City of Vista and the City of Carlsbad, and are maintained by the City of Carlsbad. The Agua
Hedionda Lift Station is maintained and operated by the Encina Wastewater Authority (EWA) by
agreement with the cities. The subject sewer improvements extend from the north side of the
Agua Hedionda Lagoon to the regional EWPCF. The new line will be located primarily within
and along the SDNR railroad right-of-way and Avenida Encinas right of way to the west of the I-
5 freeway. The proposed sewer support bridge would also provide the lagoon crossing for the
Coastal Rail Trail, a separate, future project in this area.
The proposed improvements are necessary as a replacement for or are in addition to the existing
sewer line and lift station, which are under -sized, outdated and in some areas nearing the end of
their useful life. These facilities, which will either be demolished or kept if in good repair and
needed to provide additional capacity, do not have sufficient capacity to convey future projected
build -out wastewater flows of the urbanized service area. The proposed project is designed of a
size adequate to convey the future anticipated build -out demand of the service area. Table 1
below shows the current, proposed, and anticipated build -out sewer flows:

III. PROJECT DESCRIPTION AND BACKGROUND
The project will remove and replace the existing sewer lift station and pipe support bridge and
will install approximately 1,400 linear feet of 54-inch sewer pipe to the north of the new lift
station location. The project will also include the construction of 3,960 linear feet of 30-inch
force main and approximately 7,020 feet of 54-inch gravity sewer south of the new lift station
location. While the existing 42-inch line north of the existing lift station will be abandoned and -a --
portion removed, the existing 42-inch line south of the existing lift station is in sufficiently good
condition that it will remain in place as a parallel line to the new force main/gravity sewer to be
constructed south of the new lift station. The existing line to remain in place will handle low and
average volume sewer flows.
Related utility relocations include the option of relocating approximately 380 feet of natural gas
transmission pipe. The owner of this gas transmission pipe (SDG&E) is presently undecided on
whether to relocate this pipe from its present support trestle bridge structure across the lagoon
channel to the proposed sewer line support bridge; and to thus demolish and remove the existing
gas line support bridge. Nonetheless, it is included in this project and the environmental impacts
associated with the gas line relocation and trestle bridge removal were included in the
environmental analysis so that if SDG&E decides to relocate the gas line and remove the trestle
bridge structure, the environmental review of this segment of the project has been completed.
Also proposed within the work area and .in an alignment parallel to the sewer line is a 12-inch
recycled water line -which will run from the north end of the project area to the south end (total
12,460 ft). This line will transport pressurized recycled water to the northern sections of
Carlsbad from the Carlsbad Water Recycling Facility, located next to the EWPCF. This recycled
line will be installed on primarily the east side of the sewer pipe. It is likely that only the portion
of recycled water line between Cannon Road and Palomar Airport Road will be constructed and
pressurized with the sewer line. Completion of the reminder will occur as additional funding
becomes available.
Further information about project description, construction phasing, staging areas, traffic control,
grading, and other related details are included as Attachment 12.
Jurisdictional Authority. Because of its location and geographic reach, the project will require
permits from a number of jurisdictions in addition to the city -issued permits. The following
paragraphs summarize the required permits and issuing authority.

Planning Commission
• Coastal Development Permit (CDP) for the section of the project south of Cannon Road.
• Special . Use Permit (SUP) for any construction. or development within the 100-year
floodplain, which in this case involves only the removal of the existing trestle bridge
pilings which presently are within the lagoon channel (the new bridge support abutments
will be constructed on the lagoon bank and a minimum of 10-feet above the 100-year
flood zone).
Housing and Redevelopment Commission (upon Planning Commission Recommendation)
Redevelopment Permit (RP) for all structures proposed within the South Carlsbad Coastal
Redevelopment Plan (SCCRP). Proposed improvements within the EPS property to
slightly south of Cannon Road are within the SCCRP.
City Council (upon Planning Commission recommendation)
• Habitat Management Plan Permit (HMP) for the impacts to native habitat necessitated -by
the construction of the pipe support bridge abutments.
• Hillside Development Permit (HDP) for the lift station structure because the proposed
site contains a slope of 15% or greater and also has an elevation differential of more than
15-feet.
• Precise Development Plan (PDP) Amendment and a Specific Plan (SP) Amendment for
all structures proposed within the EPS property.
• SP 144 Amendment for all structures proposed within the SP boundary.
California Coastal Commission
• Coastal Development Permit for all proposed work north of Cannon Road to the northern
end of the project, including the SLS. This area is within the Agua Hedionda segment of
the City's Local Coastal Program, where the California Coastal Commission has retained
permitting authority.
Resource Agencies
• U.S. Army Corps of Engineers (Section 1.0 of the River and Harbors Act — 404 Permit).
• Regional Water Quality Control Board (Section 401 of the Clean Water Act — 401.
Certificate).
• California Department of Fish and Game (Section 1600 — Streambed Alteration
Agreement) for the removal of the existing trestle bridge(s) and construction of the new
bridge over the Agua Hedionda Lagoon channel.
There are no unresolved issues. The staff recommendation approval with conditions is supported
by the analysis as follows.

I. Growth Management (Chapter 21.90 of the Carlsbad Municipal Code).
A. General Plan
The General Plan designates the EPS and adjacent SDG&E properties for Public Utility (U) us.es......
The General Plan Land Use Element describes this category of land use as applied to "...areas,
both existing and proposed, either being used or which may be considered for use for public or
quasi -public functions." The Land Use Element also states that U designation's "primary
functions include such things as the generation of electrical energy, treatment of waste water,
public agency maintenance, storage and operating facilities, or other primary utility functions
designed to serve all or a substantial portion of the community." The proposed SLS and other
project components in the "U" land use designation are consistent with this description,
particularly in that they are designed to serve much of Carlsbad.
The various pipelines proposed for the project are located within several different land use
designations. Installation of pipelines is considered to be consistent with the Land Use Element
in that pipelines are allowed in all General Plan land use designations. Further, since they would
be placed underground, would be generally located in street and railroad right of ways, and
would cause only limited, impacts to sensitive native habitats (pipe support bridge abutments),
the proposed pipelines are consistent with General Plan policies requiring development to protect
and enhance the City's environment, character, and image.
In addition, staff finds the project is consistent with the General Plan as discussed below:
a. The proposed SLS and additional sewer piping is needed to ensure adequate provision of
sewer service into the future and will protect the quality of the lagoon and sensitive habitat in
the area by locating the SLS further to the east, installing modern equipment, and replacing
the fragile wood trestle that currently encroaches in the lagoon. These elements are
consistent with Land Use Element Growth Management and Public Facilities Goal A.1,
which states, "A City which ensures the timely provision of adequate public facilities and
services to preserve the quality of life of residents."
b. The proposed SLS will replace an existing sewer lift station that is old and not adequately
sized to accommodate planned growth per the existing Carlsbad and Vista General Plans. In

addition, the project would result in more efficient and reliable wastewater transport to the
EWPCF. The project is consistent with the Lane Use Element Growth Management and
Public Facilities Goal A.2, which states, "A City which maintains a system of public facilities
adequate for the projected population" and Goal A.3, which states, "A City that responsibly
deals with the disposal of solid and liquid waste."
c. The proposed SLS will be constructed within the existing hillside away from the lagoon and
will not be visible from the south and east, nor will it block lagoon or ocean views. In
addition to its sensitive site design, both the SLS and the proposed pipe support bridge use
colors and materials that blend with their surroundings. Furthermore, the proposed pipe
support bridge will be constructed to allow for the future Coastal Rail Trail. These elements
are consistent with Land Use Element Environmental Implementing Policies and Action
Programs C-5, which states, "Limit future development adjacent to the lagoons and beach in
such a manner so as to provide to the greatest extent feasible the physical and visual
accessibility to these resources for public use; and enjoyment."
d. General Plan Circulation Element Scenic Roadway Policy C.1 requires implementation of the
Carlsbad Scenic Corridor Guidelines. This 1998 document addresses the appearance of
development along the railroad corridor and states buildings adjacent to the railroad shall be
"architecturally articulated" and present a "pleasant facade." The SLS as well as the pipe
support bridge achieve this desired goal through site and structure design and colors and
materials. The SLS, for example, will be constructed mostly below the surrounding finish
grade level to preserve the natural contours of its hillside setting. Further, the low profile
structures will have a flat roof with square and rectangular shapes architecturally articulated
to vary building elevations and facades. The visible portions of the walls of the structures will
be accented and shadowed with textured and geometric patterns and earth tone colors to
blend it with the surrounding hillside. Furthermore, landscaping with native plants will be
planted in front of the buildings to soften the structures appearance.
B. Title 21 (Zoning) and Precise Development Plan (PDP 00-02)
Background
The EPS site has a Public Utility (P-U) zoning, which implements the corresponding General
Plan U land use designation. Section 21.36.020 of the Public Utility Zone lists permitted uses
and structures, including wastewater treatment, disposal or reclamation facilities. Accordingly,
as a proposal to enhance and replace the existing sewer lift station and related pipelines, the
project is a permitted use in the P-U Zone. Section 21.36.030 of the P-U Zone prevents the
issuance of any building permits or entitlements "... until a precise development plan has been
approved for the property." Consistent with this requirement, PDP 00-02 was approved in 2006
for the EPS and most recently amended in 2009 for changes to the desalination project (PDP 00-
02(13)). This PDP serves as the primary entitlement for the SLS.

The proposed SLS and appurtenances require an amendment to the PDP. However, these
amendments are relatively minor since there is an existing sewer lift station located on the EPS
and acknowledged in the PDP and because the project is a permitted use in the P-U zone, The
amendment primarily consists of updating the PDP text and graphics to recognize the new
location of the proposed SLS and the removal. of the existing sewer lift station and overflow
basin. Other "housekeeping" changes are proposed to update the PDP contents (e.g., to reflect
that the desalination plant is an approved, not proposed project) and list 'the various regulations
applicable to proposals within it. No standards of the PDP would be changed by the proposal.
The project complies wi`tli the requirements of the P-U zone and PDP 00-02(B). Attachment 13
is a table that provides a detailed analysis of project compliance with applicable development
standards.
C. Encina Specific Plan (SP 144)
Adopted in 1971 and amended several times since, the Encina Specific Plan encompasses 680
acres and spans a two-mile distance from the Pacific Ocean to just east of Cannon Road near its
intersection with Faraday Avenue. Within its boundaries are the EPS, Agua Hedionda Lagoon
east and west of Interstate 5, and adjacent areas,
Specific Plan 144(H), an action approved with the desalination project in 2006, incorporated
PDP 00-02 by reference. The Specific Plan states that it must be amended if the PDP is
amended. Since the proposed project would amend PDP 00-02, it triggers an amendment of the
Encina Specific Plan.
In 1998, the City Council adopted a Resolution. of Intention (ROI Reso. No. 98445), directing
city staff to study and consider a comprehensive land use plan for properties within Specific Plan
144 (SP-144). The study was not done, but subsequent actions of the City Council reconfirmed
that a comprehensive specific plan update is necessary, and that it should be applicant, rather
than city -initiated.
However, in 2002, the City Council, in Agenda Bill 16,790, directed that any applicant of a
proposed project within the Specific Plan area be required to prepare a comprehensive update of
the specific plan. This direction was revised in 2003, when the City Council passed Resolution
2003-208, allowed the PDP and Desalination Plant project to be processed as an amendment to
the Encina Specific Plan 144 rather than through a comprehensive update of the specific plan.
While the proposed SLS project is an improvement partially within SP-144, it is not subject to
the comprehensive update requirement because it does not trigger or significantly impact the land
use, public access and other issues of concern identified in the 1998 ROI. Specifically, the
project is not subject to the comprehensive update requirement for the following reasons:
a. The project improves major regional infrastructure that cannot be feasibly relocated. The
project will replace existing facilities which have reached the end of their useful life.
It,� u',

Paae 8
b. The lift station and pipelines are not significant new land uses; they would improve existing
like facilities and would be constructed in generally the same locations as those existing
facilities. They would be located in an existing utility corridor bordered on the west side by
the railroad. The majority of the pipeline portion of the project within SP-144 would be
underground. Furthermore, care has been exercised in the design of above -ground structures
such as the proposed lift station that features a low profile and partially buried structure and
the replacement bridge for the sewer line.
c. As a replacement and expansion of existing, like utility uses in generally the same location,
the project would not represent a new, significant impediment to addressing the issues
identified in the ROI, including land use and public access.
d. The project proposes no changes to general plan land use or zoning designations or any
conditions or policies of SP-144.
e. As discussed in this section, the project complies with all applicable land use documents
affecting the SP-144 area, including the General Plan, Zoning Ordinance, Precise
Development Plan, South Carlsbad Coastal Redevelopment Area Plan, Agua Hedionda Land
Use Plan, and Scenic Corridor Guidelines.
f. The project would result in only minor changes to the latest adopted versions of the Encina
Specific Plan and the PDP (SP-144(J) and PDP 00-02(B)) in the form of text and graphic
changes that merely recognize the proposed improvements and make clarifications.
Consistent with SP 144(J) and PDP 00-02(B), these minor changes are considered "formal
amendments" to the documents.
Since the project would not require a comprehensive update, it instead proposes an amendment
to SP-144. The amendment enables the project to continue to be a part of SP-144 and subject to
any future comprehensive review. As part of the amendment, the minor changes proposed to the
SP-144 text and graphics reference and briefly describe the new SLS and PDP 00-02(C). Minor
"housekeeping" revisions are also proposed to standardize references to SP-144 and note the City
Council's requirement to comprehensively update the specific plan. Proposed revisions would
also clarify the Council's discretion to waive or modify this update requirement as is
recommended for this project by way of the amendment proposed.
The proposed project complies with applicable Specific Plan standards and requirements adopted
over the years regarding architectural review, building height, and exterior lighting, as is
discussed in detail in Attachment 13.
D. South Carlsbad Coastal Redevelopment Plan
The South Carlsbad Coastal Redevelopment Plan (SCCRP), adopted in 2000 and amended in
2005, establishes a 555-acre redevelopment area that includes the portion of the project from
approximately the proposed SLS to Avenida Encinas, a few hundred feet south of the Cannon
Road area. The SCCRP is in effect through 2030. The stated goals that are applicable to the
project include:

• Eliminating blight and environmental deficiencies in the Redevelopment Project Area.
• Strengthening the economic base of the Project Area and the community by the
installation of needed on- and off -site improvements to stimulate new
commercial/industrial expansion, employment and economic growth.
• Developing new beach and coastal recreational opportunities.
The project will achieve these key goals of the redevelopment plan by replacing an existing
sewer lift station, which is blighted, under -sized, outdated and nearing the end of its useful life.
The project also includes the installation of a 12" recycled water line, which will run the length
of the project. The recycled water line will improve the reliability and water quality of the City's
recycled water system and will provide adjacent commercial, industrial and office sites a reliable
water supply for landscaping as an alternative to using potable water that is in short supply.
Furthermore, the pipe support bridge over the Agua Hedionda Lagoon is being designed to
accommodate the future Coastal Rail Trail through this area, which will allow pedestrians and
bicyclists recreational opportunities adjacent to the lagoon and coast.
SCCRP Section 527 requires all property within the Redevelopment Plan boundaries to be
developed, redeveloped, or rehabilitated in conformance with the goals and provisions of the
Plan and the requirements and regulations of the General Plan, Zoning Ordinance, and any other
state or local requirements, such as guidelines and specific plans. Further, Section 601 indicates
the permitted land uses within the Plan boundaries are those permitted by the General Plan,
Zoning Ordinance and all other state and local requirements.
Exhibit C of the SCCRP lists proposed projects and infrastructure improvements and identifies
"Commercial Rehabilitation and Economic Development Programs", which facilitate
development of modern industrial, commercial, and utility facilities. An amendment to SCCRP
Section 601 passed and adopted in November 2005, states that specific uses, including a
"wastewater treatment plant" may be permitted in the Redevelopment Plan only if the Housing
and Redevelopment Commission finds all of the following are satisfied:
• The Commission approves a finding that the land use serves an extraordinary public
purpose;
• That the Commission approves a Precise Development Plan or other appropriate planning
permit or regulatory document; and
• That the Commission has issued a Redevelopment Permit.
A. Redevelopment Permit and Precise Development Plan are included in this project. As stated
above, the Housing and Redevelopment Commission must also make a finding that the proposed
project serves an extraordinary public purpose. Evidence to support making this finding is
provided below.
• As mentioned above the existing sewer lift station and pipelines, which was constructed
in 1964 and rehabilitated in 1989, are under -sized, outdated, and in some areas nearing
the end of their useful life. These facilities also do not have sufficient capacity to convey

future projected buildout wastewater flows of the urbanized service areas of the cities of
Carlsbad and Vista. The proposed project is designed of a size adequate to convey the
future anticipated buildout demand for the two cities and features modern components to
improve reliability and functionality.
• The proposed project will be located to the east of the existing sewer lift station and thus
further away from the lagoon to protect the sensitive resources in and adjacent to the
lagoon. Furthermore, the proposed project will be constructed primarily underground and
will not be visible as viewed from the east and south by motorists, passengers and
pedestrians in the area.
The proposed project will allow for the dismantling and elimination of the existing lift
station structure, over flow basin, and trestle -style wood bridge(s), including the removal
of the pilings that are located in the lagoon channel, which would be considered a
beneficial impact to the lagoon and visual character of the site.
• The lagoon channel bridge is being constructed to accommodate the future Coastal Rail
Trail through this area, which will enhance recreational activities where none exist
through this area.
Overall, the proposed project does comply with the applicable goals and requirements of the
SCCRP, including the finding of extraordinary public purpose.
E. Local Coastal Program
Review of Required Coastal Findings
The project affects two parts of the City's Coastal Zone: the Mello II segment and the Agua
Hedionda Land Use Plan segment. The latter segment encompasses the Encina Power Station,
the lagoon, and property around the lagoon. Pipeline from the northern end of the project to
Cannon Road, including the sewer lift station, are located in the Agua Hedionda Land Use Plan
segment. Pipelines proposed south of Cannon Road are in the Mello II segment. Municipal
Code Chapter 21.203, Coastal Resource Protection Overlay Zone, is also applicable to the project
since the Overlay applies to all Coastal Zone properties.
While the City has authority to issue the necessary CDP for pipelines in the Mello II segment, the
California Coastal Commission (CCC) has retained the authority to issue the CDP north of
Cannon Road, which includes the pipe support bridge and the SLS in the Agua Hedionda Land
Use Plan segment. Staff s analysis of the projece's compliance with the Local Coastal Program
(LCP) includes review of this segment.
Staff finds the proposed project is consistent with applicable Local Coastal Program policies as
follows:
• Coastal Act Compliance:
o The project is located within the California Coastal Zone, specifically within the Agua
Hedionda and the Mello II segments of the adopted LCP. The portion of the project

north of Cannon Road is in the Agua Hedionda segment, and south of Cannon Road
is in the Mello Il segment. While the Agua Hedionda Land Use Plan has been
adopted by the City of Carlsbad, no Implementation Plan has been certified by the
CCC to date, and thus the CCC retains coastal permit authority for improvements
within this segment. The Agua Hedionda land uses are generally consistent with the
Carlsbad General Plan land uses for the project alignment within the Agua Hedionda
LCP segment, which allows the proposed underground infrastructure project within
the public right-of-way on Avenida Encinas, south of Cannon Road. The proposed
project is consistent with this policy.
Agua Hedionda Land Use Plan Segment:
o Agua Hedionda LCP Coastal Act Policy 30230 Marine Resources. The project
complies because the project avoids impacts to marine resources as the proposed
bridge structure will completely span the entire channel width. Furthermore, the
project will remove the existing trestle bridge structure which supports the existing_-.-
42-inch sewer pipe. The sewer line bridge structure contains eight (8) narrow bridge
support/pilings which presently sequence across and into the bottom of the Agua
Hedionda Lagoon channel. These support/pilings are 14-inches in diameter, and set
approximately 20-feet below the mud line on the bottom of the lagoon, and create
some measurable amount of water friction through the channel, which will be
eliminated through implementation of the project. Once removed, the in -channel
piling holes will partially collapse and then fill with sand -and sediment from the tidal
action. As an option, the existing natural gas transmission line bridge may also be
removed. This bridge contains four driven wood piles (two on land and two in the
channel). The natural gas bridge would be removed in the same fashion as the
existing sewer trestle bridge. As a result of these factors, there is a potentially
beneficial impact to marine resources.
o Agua Hedionda LCP Coastal Act Policy 30231 Biological Resources. The project
complies because it will not impact the biological production and the quality of Agua
Hedionda Lagoon. In fact, the project will have a positive impact to biological
resources particularly when compared to the existing facilities it will enhance and
replace, Specifically, the project replaces outdated infrastructure and increases the
redundancy, capacity, and reliability of the sewer system. Additionally, the proposed
SLS will be located further from the lagoon when compared to its existing location
and will incorporate measures to treat stormwater and site runoff during and after
construction. Finally, the proposed sewer support bridge spans the lagoon and features
no in -water supports, unlike the current bridge it will demolish and replace.
o Agua Hedionda LCP Coastal Act Policy 30240(a) Environmentally Sensitive Habitat
Areas (ESHA). ESHA is defined in the Coastal Act Section 30107.5 as, "Any area in
which plant or animal life or their habitats are either rare or especially valuable
because of their special nature or role in an ecosystem and which could be easily
disturbed or degraded by human activities and developments." The project complies
because the project avoids impacts with sensitive habitats, with the exception of a
small disturbed area of Diegan coastal sage scrub (DCSS) habitat. However the

DCSS in this area is not rare or especially valuable because it is in a series of small,
fragmented, isolated patches, surrounded by a highly urbanized environment. Nor is
the impacted vegetation especially valuable to the ecosystem since the area has
already been largely degraded by urbanization, industrialization and the adjacent
railroad. As a result of these factors, the project is not considered an environmentally
sensitive habitat area, or ESHA. Notwithstanding that the project will not impact
ESHA, it will mitigate for the 0.0.5 acres of DCSS that will be impacted through
compliance with the mitigation measures identified in the Mitigation, Monitoring and
Reporting Program (MMRP). Additionally, though the proposed sewer support
bridge over the Agua H�,dionda channel crosses identified hardline open space, it will
be situated 17-feet above the surface of the water, and thus will not impact any
hardline habitat.
o Agua Hedionda LCP Coastal Act Policy 30240(b) Environmentally SensitiveHabitat
Areas. The project complies because it will be sited and designed to prevent impacts
which would significantly degrade Agua Hedionda Lagoon.
o Agua Hedionda LCP Policy 1.9. This policy limits building heights to 35 feet. The
SLS, the only project building, is partially buried to minimize its presence and has a
maximum height of 25.5 feet.
o Agua Hedionda LCP Policy 6.7. The project complies with this policy, which
encourages the maintenance and expansion of lagoon recreational uses, by facilitating
extension of the Coastal Rail Trail via the proposed sewer support bridge over the
lagoon.
• Mello II Segment:
o Carlsbad LCP Mello II Policy 3-4 Grading and Landscaping Requirements. The
project complies because all graded areas will be improved or landscaped which will
minimize erosion. Also grading will not occur during the rainy season unless
sufficient erosion control measures have been included in the project construction
program.
o Carlsbad LCP Mello II Policy 4-3 Accelerated Soil Erosion. The project complies
because:no portion of the project is being developed on steep slopes as identified in
the LCP. The project also complies because the project will incorporate BMPs and
submit a water quality technical report as specified in the National Pollutant
Discharge Elimination System (NPDES) permit and in the Standard Urban
Stormwater Mitigation Plan (SUSMP). In addition, the city will include requirements
in the CDP approval to allow inspection and maintenance of the BMPs, and the
project minimizes land disturbance activities during construction (e.g., clearing,
grading and cut -and -fill). BMPs are also proposed to treat site runoff following
construction of the SLS.
o Carlsbad LCP Mello II Policy 4-4 Removal of Natural Vegetation. The project
complies and will not significantly contribute to the removal of vegetation because it
will minimize the sensitive vegetation impacted and will mitigate for that removed.
o Carlsbad LCP Mello II Policy 4-5 Soil Erosion Control Practices. The project
complies because onsite erosion will be avoided as a result of the use of silt fences,

• Coastal Resource Protection Overlay Zone:
o The project complies with Municipal Code Section 21.203.040 A. regarding
preservation of steep slopes with native vegetation as it does not impact any such
features. The SLS will be constructed into an existing hillside without native
vegetation and the pipelines are proposed in roadways or already disturbed areas.
o The project complies with Municipal Code Section 21.203.040 B. regarding drainage
and erosion as the MMRP includes mitigation measures to address drainage, erosion
control, sediment control and storm water quality, as set forth in the NPDES permit
and other required standards and permits.
o The project complies with Municipal Code Section 21.203.040 D. regarding
development in liquefaction -prone areas as the MMRP includes a mitigation measure
to address potential settlement due to seismically -induced liquefaction or later spread.
F. Hillside Development Ordinance (Chapter 21.95 of the Carlsbad Municipal Code)
The key purpose and intent of the Hillside Development Ordinance is to assure hillside
conditions. are properly identified and incorporated into the planning process, and to preserve
and/ enhance the aesthetic qualities of natural hillsides and manufactured slopes of the land,
minimizing the amount of project grading, especially in highly visible public places. The project
is subject to this ordinance due to its proposed grading and construction of the SLS on the north -
and west -facing slopes of Agua Hedionda Lagoon and installation of a new gravity sewer line
and other infrastructure on both sides of an .existing man-made slope just north of the lagoon.
The reminder 'of the project is on flat or gently sloping topography and is not subject to the
ordinance.
The applicant has submitted the required slope analysis and profiles that identify the slope
conditions. The project area in which the SLS is proposed consists of an existing manufactured
slope with slope gradients over forty percent, and slope heights that exceed fifteen feet. The
project does include grading of a portion of the slope with an inclination of greater than 40
percent; however, per Section 21.53.230 this only applies to natural slopes and not manufactured
slopes. The hillside where the SLS will be constructed was manufactured, which is defined as a
man-made slope consisting wholly or partially of either cut or fill material. As shown on Figure 2
of the Geotechnical Evaluation Report, prepared by Ninyo & Moore, dated August 3 2009, the

lower pad area of the lift station site and adjacent 2:1 slope are manufactured from fill material
that was likely dredged from the lagoon.
In addition, the proposed alterations of this slope to accommodate the SLS have grading
quantities that exceed 10,000 cubic yards per acre. However, per Section 21.95.140 D —
Modifications to the development and design standards, development on land designated for
nonresidential development is not required to comply with the Hillside Development
Ordinance's volume of grading as long as the proposed grading can be justified.. As explained
below, staff finds the proposed grading volumes acceptable as well as overall compliance of the
project with hillside standards.
In order to maintain the integrity of the existing hillside, the grading quantities proposed are
necessary to enable the SLS structures to be constructed mostly below the surrounding finish
grade level, which preserves the existing contours and elevation of the hillside. The large, main

G. Special Use Permit (Floodplain)
Projects located within any area of special flood hazards must obtain approval of a Special Use
Permit (SUP) by the floodplain administrator (the City Planning Commission). The intent of
these regulations is to promote the public health, safety, and welfare and to minimize public and
private losses due to flood conditions. Chapter 21.110 states that "Flood losses are caused by the
cumulative effect of obstructions in areas of special flood hazards which increase flood heights
and velocities, and when inadequately anchored, damage uses in other areas."
The project does not propose any structures within the 100-year flood hazard area, but a SUP is
required because of the bridge demolition work proposed over Agua Hedionda Lagoon. As
mentioned previously, the project will remove the existing trestle bridge structure which supports
the existing 42-inch sewer pipe. Optionally, the structure supporting the 12-inch high pressure
natural gas transmission line may be removed. The sewer line bridge structure contains eight (8)
narrow bridge support/pilings which presently sequence across and into the bottom of the Agua . .
Hedionda Lagoon channel. These support/pilings are 14-inches in diameter, and set
approximately 20-feet below the mud line on the bottom of the lagoon, and create some
measurable amount of water friction through the channel, which will be eliminated through
implementation of the project. No equipment will be located in the lagoon.
Once removed, the in -channel piling holes will partially collapse and then fill with sand and
sediment from the tidal action. As an option, the existing natural gas transmission line bridge
may also be removed. This bridge contains four driven wood piles (two on land and two in the
channel). The natural gas bridge would be removed in the same fashion as' the existing sewer
trestle bridge. As a result of these factors, it is determined that no impacts (and potentially a
minute beneficial impact) to the 100-year flood hazard area would occur from implementation of
the project. Therefore, the proposed project would be in compliance with the Floodplain
Management Regulations.
H. Habitat Management Plan
Vegetation which would be impacted through implementation of the project includes Diegan
Coastal Sage Scrub (unoccupied by the California gnatcatcher) (Habitat Group D), Non-native
Grassland (Habitat Group E), Eucalyptus Woodland (Habitat Group F), Disturbed; Land (Habitat
Group F), and Developed Land. Permanent impacts for the project will total 3.24 acres and
temporary impacts will total 7.35 acres. Permanent impacts are those associated with the
construction of the pump station facility, those impacted by permanent grading, and those
associated with the Agua Hedionda channel bridge abutment and support foundation structures.
This project is covered under the HMP, and therefore is eligible to mitigate upland habitat
impacts through the Lake Calavera Mitigation Parcel. Mitigation measures are included to
require debiting the appropriate acreage from the Lake Calavera Mitigation Parcel at the ratios
indicated in Table 4 of the MMRP under Biological Resources, except that Conservation
Standards 7-8 and 7-9 (p. D-115) of the HMP require that Diegan coastal sage scrub mitigation

acreage must include a minimum 1:1 creation component (minimum of 0.05 acre creation).
Therefore, project mitigation for DCSS will include a minimum of 0.05 acres of credit debiting
from the Lake Calavera Mitigation Parcel, and also an additional 0.09 acre of revegetation
(creation) of DCSS on or near the impact location, The 0.09 acres of revegetation (creation) of
DCSS is expected to occur within and around the eastern half of the demolished, filled -in
existing lift station overflow basin, but could occur in a different location in the area.
Through design and mitigation, the project avoids and minimizes impacts to habitat. With
mitigation measures included in the project's MMRP, all identified impacts can be shown to be
consistent with the HMP and reduced to a level of insignificance. Furthermore, the project is
consistent with Municipal Code Chapter 21.210, Habitat Preservation and Management
Requirements, and is conditioned consistent with the management, maintenance, and monitoring
standards of Section 21.210.14.
I. Growth Management
The project alignment is located within Zones 1, 3 and 22 Local Facilities Management Plans
(LFMP) areas. The pipe support bridge and piping to the north of the bridge are located in Zone
1. The SLS and piping to the south to Palomar Airport Road are located within Zone 3, and all
piping south of Palomar Airport Road is within Zone 22. The zones identified above implement
the Citywide Facilities and Improvements Plan and LFMPs for various geographic areas of
Carlsbad. The LFMPs were adopted to ensure that growth occurred in concert with public
facilities and service systems.
The City's fire, schools, libraries and parks and recreation performance standards were developed
assuming population growth occurs through the construction of additional dwelling units.
However, the proposed project does not include residential uses, and does not include any
components that would result in an increase in population or any public facility or infrastructure
demand that might result from commercial or other non-residential land uses. Furthermore,
project operations will not result in any increased traffic and will thus not result in any
substantial deterioration of the public roadway system, nor generate a need for other
governmental services, such as emergency services. Replacement of the existing sewer lift station
and force main is designed of a size adequate to convey the future anticipated build -out demand
of the service area.
V. ENVIRONMENTAL REVIEW
Staff conducted an environmental impact assessment to determine if the project could have a
potentially significant effect on the environment pursuant to CEQA Guidelines and the
Environmental Protection Ordinance (Title 19) of the Carlsbad Municipal Code. The assessment
determined the project has potentially significant impacts in the areas of air quality, biological
resources, cultural resources, geology/soils, hazards/hazardous • materials, land use,
transportation/circulation, and mandatory findings of significance. To reduce these potentially

significant impacts to a less than significant level, mitigation measures contained in the projects
MMRP, are required.
Based on the above, the City Planner issued a Notice of Intent to adopt a MND for the project on
August 13, 2010 and sent it to the newspapers, County of San Diego, and the State Clearinghouse
for a 30-day public review (August 17, 2010 — September 16, 2010). One comment letter was
received during the 30-day public review from Preserve Calavera. The comment letter, and
staff s response to the letter, are included as part of the Planning Commission Resolution for the
MND.
The project was modified slightly after the public comment period to increase the proposed fl-
inch potable water line to 6-inch per the City of Carlsbad Fire Department's requirements to have
enough water pressure available to operate a proposed fire hydrant on the EPS site. The increase
in the potable water line will allow for an additional 1,000 gallons per minute (GPM) of water
flow to be delivered to the site in the event of a fire. The minor increase in pipe size and water.. .
flow does not require recirculation of the Mitigated Negative Declaration in accordance with
CEQA Section 15073.5(c)(2), since the increase in the potable water line and water flow is only
to accommodate a fire hydrant, and therefore does not constitute a significant project
modification nor create a new avoidable significant effect. A memo stating the change to the EIA
Part II is included as part of the Planning Commission Resolution for the MND.

2. Pervious surfaces. Pervious gravel or earthen cover will be utilized over a portion of the lift
station site. These surfaces will capture stormwater and allow it to infiltrate into the ground
instead of running off the surface, and off of the site.
3. Infiltration basin. An infiltration basin will be located at the south end of the site. This basin
will be designed to use the natural filtering ability of the soil to remove pollutants from site
stormwater runoff.
SLS Equipment Redundancy. The SLS is designed to handle full anticipated build -out demand (33
mgd PWWF) of the service area. The SLS design also incorporates extensive equipment redundancy
for ensuring that equipment failures do not result in sewage spills. The redundancy concept involves
a lift station configuration that includes two independent pumping elements; the "lift" side and the
"force main" side. The lift side of the station includes four 40 hp pumps. The force main side of the
station includes four 100 hp pumps. The total pumping capacity of the station is up to 23.5 mgd on
the lift side and up to 26.5 mgd on the force main side. The total station capacity is 50 mgd
providing 50% redundancy at PWWF conditions (33-mgd) and over 100%. redundancy at PDWF (21
mgd). The force main side and lift side can independently pump PDWF (21 mgd). In the event that a
total mechanical failure occurs on either side, the station will remain operable without consequences
under PDWF conditions, and contains power redundancy and significant upstream storage capacity
(both described below) under catastrophic circumstances were they to occur under peak wet weather
conditions,
SLS Electrical Redundancy. The station is also equipped with multiple redundant features in terms
of emergency back-up power. It is designed with two independent electrical circuits (primary and
secondary) plus a generator, for a total of three independent power sources and will include an
automatic standby transfer switch in the event of catastrophic electric failure. In the event of full
regional blackout, emergency power will be provided by a built-in onsite diesel fuel generator.
Under such emergency conditions, the generator will provide power. to all SLS facilities. The
generator has the capacity to store enough fuel for 24 hours of operation. Under such circumstances,
the station is designed with alarms to alert officials to any electrical problem and to enact the
contingency plans to reduce flow into the SLS (upstream lift stations contain storage volume) under
such circumstances, if necessary. The upstream pipe also contains a significant amount of storage
capacity, which can gradually fill up to allow the time necessary to resolve a problem, should it
occur.
Hazardous Materials. Outdoor material storage areas, including the future chemical storage area at
the SLS will be designed to reduce pollution introduction. Hazardous materials with the potential to
contaminate urban runoff will be; 1) placed in an enclosure such as, but not limited to, a cabinet,
shed, or similar structure that prevents contact with rain, runoff or spillage to the storm water
conveyance system; and 2) protected by a surrounding series of secondary containment structures
such as berms, dikes, or curbs. The storage area will be paved and sufficiently impervious to contain
leaks and spills, and will also be designed with a roof or awning to minimize direct precipitation onto
and within the secondary containment area.
Construction Description
As mentioned previously, the project will be constructed in three phases. The schedule for
construction of these phases could be separate, could overlap, or could be constructed
simultaneously. Re-routing of the 12-inch high pressure natural gas transmission line, installation of
the 12-inch recycled water line, and replacement of the 3-inch potable water line with a 6-inch water
line is anticipated to occur with each adjacent segment of sewer construction; however, as noted
ATTACHMENT 12
Page 6
earlier, it is likely that only the portion of recycled water line between Cannon Road and Palomar
Airport Road will be constructed and pressurized with the sewer line due to funding limitations.
The construction/installation of the pipeline portions of the project will be accomplished through
both conventional open -trench method, and through trenchless construction tunneling techniques
(i.e.; horizontal directional drilling and micro -tunneling). Trenchless construction/tunneling of the
sewer lines will be used in areas where a high number of existing underground utilities must be
avoided, or where open trenching would result in traffic disruption in high traffic areas, such as
through the Cannon Road and Palomar Airport Road intersections with Avenida Encinas.
Construction will occur in three phases, with the middle portion of the project at the EPS facility
being last. Phase 1 includes improvements -from a point approximately 300-feet south of Cannon
Road to the southern, limit of the project at the EWPCF. Phase 2 encompasses construction from the
north end of the project near Chinquapin Avenue to the southern abutment of the proposed sewer line
support bridge over Agua Hedionda Lagoon, located just north of the SLS. The third phase of
construction would extend from the south end of the support bridge to the north end of the Phase 1
improvements just south of Cannon Road.
Construction Phasing
Phase 1. Phase 1 involves installation of the gravity sewer main from a point approximately 300=feet
south of Cannon Road- to the southern limit of the project at the EWPCF. At the upstream end of
Phase 1, the sewer line will be installed via standard open trenching construction method. The
trenching will be accomplished within the existing Avenida Encinas hardscape median southerly to a
point approximately 1,500 feet northerly of Palomar Airport Road. At this point, microtunneling
trenchless construction will be used to burrow the sewer line under and beyond the Palomar Airport
Road intersection, to a point where it will exit approximately 650 feet south of the intersection.
Microtunneling construction necessitates the temporary placement of jacking and receiving pits
(approximately 20-feet wide by 40—feet long and 12-feet wide by 20-feet long, respectively) at the
beginning and end of each tunneling segment length. The remaining length (approximately 1,500
feet) of the alignment south of Palomar Airport Road to the EWPCF will be installed through open
trench construction within the Avenida Encinas roadway pavement area. All of the recycled water
line installation will be via open trench method.
Phase 2. Phase 2 begins at the northern end of the project. Temporary chain link fencing will be
placed around the perimeter of the work area. The sewer line alignment between the northerly
connection and the channel bridge location -will be graded. This grading will necessitate the import
of approximately 7;000 cubic yards of fill soil so that the existing berm can be widened and
heightened (by approximately 3-feet) to accommodate the soil cover necessary for the larger (54-
inch) proposed underlain pipe. A temporary above -grade by-pass pumping system which will run
along the western edge of the work zone will be utilized during the construction period to convey
sewage while the existing, aged 42-inch sewer pipe is removed. This temporary by-pass system will
involve an 18-inch temporary bypass pipe with multiple pumps, situated at the north end of the
project, routing to the existing lift station.
Southward, the new 54-inch sewer pipe, 12-inch recycled water line and 6-inch potable water line
will then be laid across the Agua Hedionda channel via the proposed pipe support bridge. This will
involve the setting of a weathered steel bridge with concrete vertical abutment supports on both the
north and south sides of the channel. The bridge will completely span the entire channel width so
that no work is needed within the 100-year flood elevation. Bridge construction will involve
approximately 800 cubic yards of excavated cut soil for the bridge abutments and footings. The
-5c f ,
ATTACHMENT 12
Page 7
existing 12-inch high-pressure natural- gas transmission line will be relocated to avoid the northerly
bridge abutment in this area. Overhead electrical distribution facilities will be relocated as needed to
provide continued service to existing customers, and minimize construction activity interference.
The bridge abutments will be constructed of concrete, and are designed with supporting retaining
walls up to 23.5 feet in height.
Phase 3. Phase 3 improvements include the sewer line from the southern end of the bridge to the
SLS, construction of the SLS and appurtenances, installation of a new 300-foot long connector sewer
line segment between the new SLS and the existing 42-inch gravity line traveling south from the
existing lift station, and installation of the force main between the new lift station and the north end
of the Phase 1 improvements. The bulk of the improvements on the south side of the Agua Hedionda
Lagoon channel will be installed through the excavation and construction of the SLS structure, and
related piping, ducting, conduits and appurtenances.
The majority of the construction work will take place on and around the SLS site. Temporary
fencing will be placed around the perimeter of the SLS work area. Soil excavation at the SLS will
involve approximately 40,000 cubic yards of soil excavation and 14,000 cubic yards of soil filling,
which will result in a net 26,000 cubic yards of soil to be exported from the SLS location. From the
south end of the SLS to a point south of Cannon Road (approximate 3,960 linear feet), the sewer line
will be installed via a HDD method. This method allows boring of a hole of sufficient size through
use of a steerable pilot hole through the ground and then a series of increasingly large drill bits along
the horizontal alignment and vertical elevation required for the pipe. The drill is guided by electro-
magnetic or GPS signals which direct the drill bit. This HDD method allows the installation of the
pipeline at the proper underground elevation and alignment without open trench disturbance to the
surface of the ground. A "drillers mud99 (bentonite clay slurry) will be pumped into the void behind
the drill bit. Bentonite is a natural mineral, which serves to cool and lubricate the drill bit as well as
stabilize and seal the drill hole against seepage and tunnel wall cave-ins until the pipe is stable. The
recycled water line along this route will however, be constructed at a much shallower depth (5-feet
below grade surface), and thus it will be laid via standard open trench construction.
Other Construction Details
Traffic Control. Work within the public streets will involve temporary control of traffic through the
work activity zone, as normal traffic flow and patterns will be disrupted, primarily within Avenida
Encinas. This work activity zone will be marked by signs, pavement markings, delineators and other
devices to provide visibility to the drivers, bicyclists and pedestrians in order to provide a safe and
efficient route through the work zone area. Detour routes will be provided as necessary. Avenida
Encinas is a four lane secondary arterial north of Palomar Airport Road and at least one lane each
direction will be kept open to traffic at all times. South of Palomar Airport Road, Avenida Encinas
becomes only two lanes (one each direction) and thus short segments of the roadway could be closed
for short periods to all except local traffic.
Along the sewer line construction lengths to be constructed through trenchless (tunneling) methods,
minimal or no impact to driveways or business operations will occur. Open trenching across the
Cannon Road and Palomar Airport Road intersections for the 12-inch recycled water line will take
place in one -lane segments so that only a single lane is closed to traffic at any time. Lane closures
across these busy roadways will be of short duration (3-days) since the recycled water line involves
only a relatively shallow 5-foot deep trench. This recycled water line installation may occur during
nighttime hours to minimize disruption to traffic flow and local businesses. Upon completion of
open trenching backfill, the trench area will be promptly capped with asphalt to return the roadway to
a smooth driving surface.
ATTACHMENT 12
Page 8
Equipment Staizing Areas. Machinery necessary to accomplish the trenching and pipe laying work
will be stored on existing adjacent pads and within closed lanes of the street. Specifically, the major
staging areas for pipes, machinery, materials and tools will be on; (a) the cleared area near the
railroad tracks at the north -end of the project; (b) on the graded pad at the YMCA site, (c)
immediately east of the proposed SLS site, and (d) the triangular shaped parcel owned by the City of
Carlsbad at the southwest corner of Avenida Encinas and Palomar Airport Road and east of the
railroad tracks. Backhoe and similar rubber -tire machinery will be primarily utilized for open
trenching, with the spoils temporarily laid directly adjacent to the trench. No machinery staging
areas will be located within sensitive biological habitat areas.
Grading. During the construction period, a total of approximately 77,471 cubic yards of soil and
gravel will be graded or trenched. Approximately 39,056 cubic yards of this excavated soil will be
used to back -fill necessary portions of the project. The remaining 38,579 cubic yards of this soil will
be exported to an acceptable offsite location. Where necessary, some high quality bedding soil
(7,069 cubic yards) and gravel (7,767 cubic yards) will be imported to the site to be placed above and
below the pipeline (within the trench) to protect the proposed sewer line. Bedding material will be
consolidated and compacted under and around the new sewer pipe and fill material will be evenly
spread and moistened or aerated, as required. Backfill material will be deposited in uniform
horizontal layers, and compressed to produce a specified relative compaction.
Construction Erosion Control. The construction activities will include appropriate temporary erosion
and sediment control protections so that all exposed soil in the area of the construction will be
protected from erosion. This will include silt fences, sandbags and straw mulch rolls being placed
around excavated trench spoils during the construction period. Also, all storm drains and natural
drainages situated downstream from the construction will be protected by linear sediment barriers or
similar erosion control devices. Weather monitoring will take place in order to avoid exposed soils
during times of heavy rainfall. The streets within and around the construction site will be swept and
maintained regularly during the construction period. The project will comply with the requirements
of the State Construction General Permit, Order No. 2009-0009-DWQ.

Mitigation Monitoring and Reporting Program; 2) a recommendation of approval for a
Precise Development Plan Amendment, Specific Plan Amendment, Redevelopment
Permit, and Habitat Management Plan Permit; and 3) approval of a Coastal Development
Permit and Hillside Development Permit, Special Use Permit (Floodplain).
The requested actions are for: 1) an amendment to the Precise Development Plan for the
Encina Power Station (EPS) and the proposed 50 million gallon per day (mgd) capacity
Agua Hedionda Sewer Lift Station and associated improvements (SLS) proposed at the
EPS; 2) an amendment to the Encina Specific Plan to incorporate the proposed SLS; 3) a
Redevelopment Permit for the SLS and associated piping within the boundaries of the
South Carlsbad Coastal Redevelopment Area; and 4) a Coastal Development Permit,
Hillside Development Permit, Special Use Permit (Floodplain), and Habitat Management
Plan Permit.
The total sewer project consists of a new 3,960-foot long force main (sewer line) and an
8,420-foot long gravity sewer line, a 50 mgd capacity SLS, associated utility relocations
(natural gas transmission and electrical overhead relocations) and a pipe -support bridge
spanning 140-feet across the Agua Hedionda Lagoon channel. The proposed project
extends a total distance of approximately 12,380 linear feet (2.35 miles) in a north -south
direction from near Chinquapin Avenue, south of Tamarack Avenue, to the Encina
Wastewater Pollution Control Facility (EWPCF) on Avenida Encinas, south of Palomar
Airport Road.
The project will be constructed in three phases within the City's Coastal Zone. The
locations and phases are as follows: Phase 1 - Cannon Road to the EWPCF within the
public right-of-way on Avenida Encinas (sewer and gravity force main and 12 inch
recycled water line); Phase 2 - south of Chinquapin Avenue to the south side of the Agua
Hedionda Lagoon within San Diego Northern Railroad (SDNR) right-of-way (gravity
sewer, including the pipe support bridge, 12 inch recycled water line and 6 inch potable
water line); and Phase 3 - southern edge of the lagoon to Cannon Road within SDNR,
NRG, SDG&E, and West Development properties and within the city's public right-of-way
on Avenida Encinas (SLS, sewer force main, and 12 inch recycled water line). The
proposed project is located within Local Facilities Management Zones 1, 3, and 22.
Mr. Neu introduced Agenda Item 1 and stated Associate Planner Pam Drew would make the Staff
presentation assisted by Senior Civil Engineer Terry Smith.
Chairperson L'Heureux opened the public hearing on Agenda Item 1.
Commissioner Dominguez stated that while he is in within 600 foot radius of the inner lagoon, the
Assistant City Attorney acknowledged he was within 600 feet of Agua Hedionda Lagoon but was not
within 600 feet of the project, therefore he would be able to participate in the meeting.
Ms. Drew gave a detailed presentation and stated she would be available to answer any questions.
Chairperson L'Heureux asked if there were any questions of Staff.
Commissioner Montgomery asked about the phases of the project. Mr. Smith stated the southern end of
the project will be the first phase because it is the area of the project that does not require any outside
agency permits for the work in Avenida Encinas. Having the section closest to the treatment plant and
connected and ready to receive sewage will make it easier to test the pumps. Commissioner
Montgomery inquired about traffic control for the project and if Staff anticipates having to close Avenida
Planning Commission Minutes February 2, 2011 Page 3
Encinas to traffic during any part of the project. Mr. Smith stated Staff does not anticipate having to close
the portion of Avenida Encinas between Cannon Road and Palomar Airport Road during the construction
of the project. During construction of the pipeline south of Palomar Airport Road, there may be periods of
time that require night work or short term road closure. Commissioner Montgomery asked what hours of
the day the roads could potentially be closed. Mr. Smith stated that many times with connections to
sewer systems, it is beneficial to do the work at night when the flows are the lowest. There will be a need
for occasional night work, but it will not be on a regular basis.
Commissioner Nygaard inquired as to how Staff calculated the eventual need for the size of the pipe. Mr.
Smith stated both the City of Carlsbad and City of Vista have recently updated Sewer Master Plans. Staff
used the projected flows from both of those Master Plans, and Staff feels very confident that the future
needs have been adequately addressed with the sizing of the pipeline.
Commissioner Dominguez asked Staff to discuss the improvements for recovery in the event of a disaster
similar to the one at the Buena Vista Lagoon. Mr. Smith stated that as part of the project, the existing
overflow basin will be removed, and Staff felt it would be best to build a sewer lift station and pipelines
that have extra reliability and redundancy. There will be two pipelines so there will be flexibility to pump
into one or both of the pipelines. Mr. Smith stated the lift station itself will have two sets of four pumps
each and there will also be redundant electrical feeds as well as an emergency generator that will have
24 hours worth of fuel storage that will run the pumps in the event of an emergency. There will also be an
emergency response plan in place. Commissioner Dominguez asked if there will be any basic changes
to the early warning system that are currently employed. Mr. Smith stated there will be state of the art
electronics and monitoring equipment. The monitoring equipment uses an auto -dialer system to go
through the phone lines or cell service and will connect to an on duty operator at the Encina Waste Water
Authority. The City of Carlsbad Maintenance and Operations staff will also receive that alarm.
Commissioner Montgomery asked what capacity and timing the city has in order to respond to an
emergency. Mr. Smith stated that it clearly depends on the time of day and the weather conditions but
there are several miles of excess capacity in those lines under normal flow conditions. Mr. Smith further
stated it would be at least a couple of hours for response time.
Chairperson L'Heureux asked how long the project will take to construct. Ms. Drew stated that the project
still needs to obtain approvals from City Council and the Coastal Commission as well as the resource
agency permits. It could take up to a year or longer to receive all the necessary approvals. Mr. Smith
stated that the construction part of the project will be approximately 18 months long for work in Avenida
Encinas. The lift station itself will take 18 — 24 months and the bridge will take approximately 12 months.
Chairperson L'Heureux asked about the process of notifying the businesses and restaurants along
Avenida Encinas. Mr. Smith stated Staff will put together a newsletter and there will be public outreach to
keep the public informed about the upcoming project. Once construction begins, Staff will work closely
with the neighborhoods and businesses to keep them informed. There will be a full time construction
manager who will be available 24 hours a day to take phone calls if need be.
Chairperson L'Heureux asked if there were any other questions of Staff.
Commissioner Siekmann asked if there will be a person to contact if work being completed at night is too
loud. Mr. Smith stated yes and that any night work will be minimized, and if the work is in the proximity of
neighborhoods or businesses, Staff would let those areas know.
Chairperson L'Heureux asked if there were any members of the audience who wished to speak on the
item. Seeing none, Chairperson L'Heureux opened and closed public testimony.
Chairperson L'Heureux asked if there were any further questions of Staff.
Commissioner Nygaard asked if there was any way to encourage the owners of the gas line to complete
their work concurrently with this project. Jane Mobaldi, Assistant City Attorney, stated that Staff has been
communicating with representatives of SDG&E and Staff can certainly encourage them to do that, but as
a practical matter that entity does not have any applications before the Commission or the City so there is
no jurisdiction over them and no way to mandate timing. Commissioner Nygaard asked if the City had
sent any letters to SDG&E requesting that the gas line be worked on concurrently. Mr. Smith stated that
Planning Commission Minutes February 2, 2011 Page 4
at this point, Staff is cautiously optimistic that SDG&E will see the benefits in putting the gas line in the
bridge. Staff is continuing to work with SDG&E on the scope and cost relocating the gas line.
Commissioner Dominguez asked where the Coastal Sage Scrub on the site will be mitigated. Ms. Drew
stated there is a mitigation parcel at Lake Calavera where credits will be purchased.
DISCUSSION
Commissioner Nygaard thanked staff for all the time and effort on the project. Because of the built-in
redundancy, this will be a great project. She stated she is happy about the rail trail as well as the color of
the fence.
Commissioner Siekmann also thanked staff for putting together a forward -thinking project. She
appreciates the visual aesthetics as well. She stated she is happy to see that there will be a biologist
onsite.
Commissioner Montgomery also stated his support of the project.
Commissioner Black also stated his support for the project. He thanked staff for all of the work done on
the project.
Commissioner Dominguez also stated his support for the project. He stated that Staff has been sensitive
in the design process of the project and is pleased with the built-in redundancy as well.
Chairperson L'Heureux concurred with his fellow Commissioners and stated his support of the project.
He feels this is truly a state of the art project and it is a very high quality project.
MOTION
ACTION: Motion by Commissioner Dominguez, and duly seconded, that the Planning
Commission adopt Planning Commission Resolution No. 6753 recommending
adoption of the Mitigated Negative Declaration and Mitigation Monitoring and
Reporting Program; adopt Planning Commission Resolutions No. 6754, 6755, 6756,

* Why Housing Element is important and how much is the annual amount of grants and funds the
city receives from SANDAL based on the city's dousing Element?
It is the primary planning tool for promoting safe and decent housing to all California families, In
creating Housing Element law, the state legislature -declared "the availability of housing is of
vital statewide importance... and is a priority of the highest order (G.C. 65580),"In addition to it
being required by low, a number of sources of funds administered by SANDAL as well as the
state (HCD) are now linked to having up-to-date housing elements. For example, to be
competitive for certain transportation grants (TDA, TransNet) SANDAG requires cities to show
that they have current housing elements certified by HCD and that they document annually their
progress in implementing housing element programs (this report), Historically, the Carlsbad has
received approximately $234,000 annually in discretionary TDA/TransNet grants subject to
Housing Element progress (see 3111108 memo to CD Director for more info).
e What is the definition of very low, low and moderate income for Carlsbad in dollar amounts?
Table 2 of Appendix A to the Agenda Bill shows the 2010 annual income limits for various income
groups by household size,
• According to Table B (part 1— Housing production Status) the city's largest deficit is in very low
income housing (1,726) and the largest over production is in above moderate housing (1,028).
What Is the city doing to encourage the production of the low income housing?
We are continuing to implement the inclusionary Mousing Ordinance and work with private for -
profit and non-profit housing developers to build inclusionary units when market rate housing is
developed. We are also continuing to work with affordable housing developers who are eager to
build new residential developments for low Income households in Carlsbad (outside the
inclusionary requirement): For example, we are currently working with the property owners of
the Holly Springs development (near the site of the new high school) to meet their Inclusionary
requirement but also to provide additional affordable units for low income households. They ore
willing to build this housing ahead of their market rate units. We are also working hard to help a
50 unit senior only, low income affordable project on Harding Street to obtain the funding they
need to build this development. As other opportunities become available, we pursue them. For
example, Solutions for Change is interested in purchasing a small apartment complex on
Roosevelt Street to rent -restrict for low and very low income households. HOMEJCDBG funds
have been recommended for approval to assist with this purchase. We also are encouraging
other affordable housing developersfowners to consider acquisition and rehabilitation projects
to provide new opportunities for low income households, andfor to consider purchase of vacant
property for the development of housing.
The greatest challenge currently to the production of additional affordable housing for low
income housing is financing. The cost of producing affordable housing still remains high, and
funding is much more limited. However, we continue to work with developers and try to identify
creative solutions to producing more housing for lour income households in Carlsbad.
* The same Table shows the city still has to build 2,562 homes, is this for this year? Now long does
the city has to build these homes? What's our total deficit in housing according to RHNA?
This figure represents the remaining need for the current housing element cycle (extended
through 2012). It is the difference between the city's allocated regional share -goals (RHNA) and
the number of new dwelling building permits issued to date. Since the production of new housing
is primarily a function of the private sector, the rate at which housing gets built is largely
influenced by market conditions. Recognizing the public sector's limited role in producing
housing, state law does not require cities to build, but rather {plan for it through appropriate
application of land use and zoning authority, removal of governmental constraints, offering
financial and non financial incentives, etc,
What's the situation with Lanakal Mobile Homes? last I heard it was at the Coastal and was
facing some difficulties. What is the city doing to help the residents there? Are there financial
help available that the city can use to assist the residents of i.anakai? (hand written page # 10)
City staff has had conversations with the residents of Canakoi Cane to inform them of the
assistance options that are available to them, which includes funding that could be authorized by
the City Council, and a state program that aids residents in purchasing their mobile homes.
These options are not available until after the subdivision is approved by the Coastal
Commission. At that time, residents could make a formal request for funding assistance to the
City Council and the state.
• Page # 10 item number 1.3. Please explain how the city is helping our residents and how many
families have been helped in the past year ... past 2 years?
To date, we have had no rental property owners who have been willing to set -aside affordable
housing units in exchange for financial assistance from the City for repairs, renovations, etc. The
City's housing funds can't be used for this rehabilitation assistance unless we can rent -restrict
units for occupancy by low income households. We, however, are still considering some
opportunities. As mentioned above, funding is being recommended through CDBGIHOME for
Solutions for Change and another developer, Southern California Housing Collaborative, to
acquire rental property and rehabilitate it in Carlsbad. These .units would then be made available
to low income households. At this time, we do not know the total number of units to be made
available but we are estimating approximately 20 additional units within the next couple of
years. City staff is also considering available property that perhaps the City could purchase for
acquisition and rehabilitation purposes to provide additional housing opportunities for law
income households.
• Item 1.4 on page #10. We've only helped 2 homes in 2010. How do you recommend to increase
this number? Two home for a city of 106,000 doesn't seem to be enough.
We have contracted with Community Housing Works to market and administer this program for
the City. CHW is continuing to try and get the word out about the availability of these funds, The
program has been marketed by the City and CHW with direct mailers to the Barrio
neighborhood, press releases, advertisements in the Carlsbad Magazine, articles and ads in the
Community Services Guide, the City's-website, Community Housing Works website, and by
referrals and word of mouth. This program is specifically far home repairs to maintain safe
homes and attractive neighborhoods, and only available to low income homeowners that occupy
the home to be repaired. A maximum loan of $5000 is available, which is forgiven in its entirety
after 5 years if owner remains in the home. The home may not be rented during this 5 year
period. Since it is a new program, it is slow to start (only 4 loans to date). But, we believe there is
a continuing need and that we should continue to market the program andmake it available.
• What happened to Seascape Village? Page 11(handwritten number)
Seascape Village Apartments was developed with financing through the multi -housing revenue
bond program in 1985. This program required that 2030 of the units (42 units) within the
development be affordable for until January, 2009. The term for the restrictions expired in 2009
and was not extended. The property was sold and the new owner was not interested in
extending the affordability requirements. The required notice was provided to tenants, and
information on other affordable housing units in Carlsbad was shared with the tenants if they
needed to relocate as a result of the loss of the restriction and an increase In rent.
• How much money is available through section 8 for Carlsbad every year? How much of it do we
use to help our residents?
For 2010-11, the City received $6,630,862 from the federal government to provide the Section 8
Rental Assistance Program in Carlsbad. A total of $5,.980,548 of those funds (or approximately
90% of funds) is used to make rental payments for our 602 household participants on the
program. The number of participating households may change from month to month. The
participating household count is as of the end of February, 2011. Approximately $620,000 (or
approximately 1090 of total funds) is used for administrationjoperation of the program.
• Where Is Table 3-12 mentioned on page 11?
Table 3-12 is found on p. 3-24 of the Housing Element, and is replicated below for ease of
reference. The table shows the city's housing capacity based on planned densities and land use
changes proposed in Housing Element Program 2.1(see pp.11-1,3 of the Agenda Bill) compared
to the city's need at the various income categories. The deficit in moderate income housing
capacity (-594) is compensated by the surplus in lower income housing capacity (4644) by 50
units.

• Where did the number 26 for our deficit of moderate homes come from? This number doesn't
match the ones on Table B.
The moderate income deficit of 26 units is derived from Table 3-12 above. The "Bridges at
Avlara" project, which was on file with the city when the Housing Element was adopted, included
a proposal to construct 76 apartments for lower income families. Those 76 units were included in
the capacity estimates shown in Table 3-12. When the Bridges application was withdrawn, the
bottom line net capacity in the Lower income column was reduced to +568 (+644-76), which,
when combined with the Moderate Income net capacity, resulted in a net deficit of 26 moderate
income units (568-594w-26).
Table B in the Agenda Bill, on the other hand, measures the number of housing units actually
produced toward meeting the RHNA goals. The difference is that Table B documents production
while Table 3-12 documents ca acit .
• Unfortunately all the projects mentioned on page 11 including Ponto, Quarry Creek and the
Bridges are subject to controversies does the city have a plan B?
.Staff is aware that proposals to increase residential densities are at times controversial. The sites
identified on page 11, however, are an important part of the city's official plan to address the
city'.s regional housing needs for the current housing cycle. As the report indicates, the
withdrawal of the Bridges application resulted in a deficit in moderate income housing capacity.
However, staff anticipates the deficit can be made up by projects currently on file, namely Dos
Colinas and Quarry Creek.
• Page 13, Mixed use residential on shopping center sites is great idea. Are we working on this
with Plaza Camino Real?
The Draft Plaza Camino Real Specific Plan (currently under Planning review) proposes to allow
residential mixed use, but does not include it with the physical upgrades currently proposed for
the site. Future projects will be necessary to construct mixed use at Plaza Camino Real.
* Page 14. Item 2.4. is requiring solar water heater pre -plumbing still being practiced in the
Planning department.
It is required as part of Carlsbad's building code.
• Page 15. In Addition to the two building seeking LEER Silver certification how many other
buildings are LEER certified in Carlsbad?
LEEO certification is administered by the US Green Building Council and occurs separate from the
city's review and approval process for development projects. City staff does not maintain data
on the number of LEE"D certified buildings in Carlsbad.
• How much in -lieu funds are available at this moment to be used for low income housing? How
much is the total collected over the years?
The affordable housing in -lieu and impact fees are deposited into our Housing Trust Fund, The
Housing Trust Fund in total is then used for administrative costs and financial assistance and
other program costs for the production of housing affordable to low income households. To date,
we have collected approximately $7.5 million total in affordable housing in -lieu and impact fees
since the lnclusionary Housing Ordinance was adopted in 1993. These funds have been used
together with other Housing Trust Fund monies to assist in the development of affordable
housing in Carlsbad, and to help fund homeless shelter and other emergency housing programs.
The Housing Trust Fund is estimated to have an unreserved cash balance of $12,884,922 in FY
2011-12.
+ Please verify that we don't have rent control In Carlsbad.
We do not have rent control in Carlsbad. A rent control ordinance for mobile home parks was
considered by ballot Initiative in the early 1990s. It was defeated, however. There have been no
additional ballot initiatives or other similar ordinances considered by the City Council since that
time.
• Page number 19, ite:m number 3.6. What is our inventory In the city's land banking program
When did this program start? How many acres have we purchased? Where are they located?
When are we planning to build low income housing there? How many nonprofit developers
have we identified? Now many units are we planning to build? What's the impact of these units
on our deficit in very low and low income housing in Carlsbad?
in general, we have not implemented this land banking program for a future development; one
that was not intended at the time of purchase. We currently do not have any vacant land that
has been purchased for, or dedicated to us for, the purpose of developing affordable housing in
the future. But, the option does remain available and we continue to look for opportunities to
purchase land for affordable housing.
From a historical standpoint, the City has purchased and does continue to own property where
there are existing affordable housing developments. The City owns the Villa Lama and Cassia
Heights properties at El Camino Real and Cassia Street, which provides for a total of 400
affordable housing units. The property is leased to the affordable housing developers/owners.
The Redevelopment agency owns the Tyler Court Apartments (75 units) on Tyler Street, and has
hired a management companyfor operation purposes. The Redevelopment Agency purchased
the property on Roosevelt Street for a future affordable housing development, and then later
identified a developer - Habitat for Humanity. The property ownership was transferred to
Habitat and the units (11 total) were sold to very low income households.
• Who controls the Housing Trust fund's $13.5 mil and how are we going to use the funds?
Ultimately, the City Council controls the use of the Housing Trust Fund, The Housing and
Neighborhood Services Department oversees the budget for the Housing Trust Fund and makes
recommendations on use of the funds to the City Council for approval The fund is estimated to
have an unreserved cash balance of approximately $12.9 million for FY 2011-12. The fund is
required to be used only for affordable housing purposes for low income households. The fund is
used for administrative costs as well as program costs for the development of affordable housing
or other shelter opportunities. At this time, we do not have a specific development requesting
financial assistance. However, we are working with a couple of developers who have inclusionary
requirements and may need financial assistance in the future. We appropriate funding from the
Housing Trust Fund on a case -by -case basis for new housing developments, and only after review
and a recommendation from the Housing Commission.
* Have the funds been transferred to the city? Did they belong to the Redevelopment agency?
We currently have several sources of funding for affordable housing developments and/or.
programs. We use CDBG, HOME, Redevelopment Housing Set -Aside Funds, and the Housing
Trust Fund, The Housing Trust Fund is the most flexible fund and does not have time limits for
expenditures. It is controlled by City ordinance and the City Council Therefore, we typically utilize
the other sources noted before we utilize Housing Trust Funds, CDBG & HOME funds are federal
funds and their use must comply with federal regulations. Use of the Redevelopment Housing
Set -Aside Funds is regulated by the State of California. We currently have an unreserved cash
balance of approximately $2 million in the Redevelopment Housing Set -Aside Fund, which we can
use for affordable housing developments at any location within the City; they do not need to be
used solely in the redevelopment areas. We do not have a project for this funding yet. We are
still looking for opportunities for expenditure of these funds. We have not yet transferred the
noted balance in the redevelopment housing set -aside fund to the Housing Trust Fund. We are
waiting for the final action by the State before proceeding with that transfer.
+� How much funds is available in Section 8 Housing Choice Voucher program? How do we inform
people of the availability of the funds and how they can qualify to receive help?
For 2010-11, the City received $6, 630,862 from the federal government to provide the Section 8
Rental Assistance Program in Carlsbad. A total of $5,980,548 of those funds (or approximately
90% of funds) is used to make rental payments for our 602 household participants on the
program. Approximately $620,000 (or approximately 10% of total funds) is used for
administration/operation of the program, Information on the program is available on the City
website and through various other referrals programs (such as the 211 information line). At this
time, however, we have a closed waiting list for this assistance. We have not received additional
funding from the federal government to expand this program in several years. Generally, the
only way in which we can assist new households, (from the waiting list) is if one of the existing
participating households ceases to use the program for various reasons or becomes ineligible or
otherwise is removed from the program. We do hove attrition and we have been able to assist
new households over the years, but the need does continue to exceed the resources available to
assist.
• Page 20, item number 3,10 last paragraph, What does this paragraph mean? What's Article 34
Authority?
Article XXXIV of the California Constitution ("Article 34") requires that voter approval be obtained
before any "state public body" develops, constructs or acquires a "low rent housing project."
This means that there must be a vote of the citizens of Carlsbad if the City or Redevelopment
Agency (itself) were to develop, construct or acquire affordable housing where more than 5180 of
the units were rent -restricted to low income households. The City has "Article 34 authority" by a
vote of its citizens for 200 senior, low income affordable units. Generally, however, we do not
have a need to obtain Article 34 authority from the voters because our affordable housing
developments in Carlsbad are constructed and additionally regulated by entities other than the
City or Redevelopment Agency, When the Redevelopment Agency purchased the Tyler Court
Apartments, we did so under the Article 34 authority granted by the voters for senior, low
income affordable housing.
• Page 20, item 3.11. Please explain the connection between the description of this item and the
comment section regarding this Item,
Though not stated in the report, to address Program 3-11, page 6-18 of the Housing Element
commits the city to adopt a reasonable accommodation ordinance and either delete or amend
the definition of family in the zoning ordinance so it is consistent with state low,
The reasonable accommodation ordinance will establish the formal policy on offering reasonable
accommodations to persons with disabilities with regard to new construction. The state
considers certain definitions of `family" to be restrictive to the siting of group homes and other
care facilities that may provide housing to disabled individuals.
• Page 20, item 2,12. What is the minimum and maximum size for a unit with three or more
bedrooms?
There is no minimum or maximum size for a 3 bedroom unit set forth in the Inclusionary Housing
Ordinance, Based an practical experience, however, these 3 bedroom units generally range in
size from about 1100 to 1350 square feet.
• Page 21, item 3.14. Have we considered specific zoning for emergency shelters in addition to La
Posada? if so,.where are they located? Now many locations?
As indicated in the report, staff is working on ordinance amendment to permit emergency
shelters by right in the industrial (M) zone and Planned Industrial (P-M) zone. Staff is still
evaluating the extent of the amendment in terms of locations and potential numbers of sites, but
the M and P-M zones largely occur in the Industrial corridor around the airport. Staff anticipates
that a draft amendment will be available for review later this year.
* Page 22, item 3.16, The Federal Government Is cutting CDBG funding, Have we thought about
solutions and where we will get the funding for some of our nonprofits in Carlsbad?
There are currently proposals for cuts in CDBG funding which range from 790 to 6.2%. However,
there have not yet been any federal approvals for any cuts to the program. For budgeting
purposes, staff has anticipated a 209& cut in funds and shared this with the CDBG advisory
committee. Any cuts in program funding will impact the City's ability to fund nonprofit
organizations providing community or social welfare services. Typically, the City has always had
requests far funding which exceeded our ability to provide funding through the CDBG program,
To address this situation, the City has set priorities for its limited funding and used an Advisory
Committee to help the Council allocate those limited resources to the nonprofits that provide the
greatest benefit to Carlsbad residents. At this time, we do not have an alternate plan for
providing othercityfunds to these nonprofits if the federal government drastically cuts the CQBG
program. We may need to find other ways to assist these organizations beyond financial
contributions if the funding cuts do occur. Staff is monitoring the federal approvals, and will
provide additional recommendations to the Council if the City is unable to move forward as
planned.
• Page 22, item 3.17. Where did the second dwelling unit recommendation from the Planning
Commission go?
The Planning Commission was briefed on the topic in 2010 and the Planning Division is preparing
to bring this item to an upcoming City Council workshop.
• Page 23, item 3.19, Did l understand it correctly? Were the number of units zero?
Correct.

IMPORTANCE OF A CERTIFIED HOUSING ELEMENT
A . s requested, this memo discusses the importance of a.certified housing. elemeni to Carlsbad
in securing funding and preserving its land use authority.
For background) the requirement per state.law for a new, certified element took effect on July
1, 2005, when the current housing cycle began. Presently, staff is working, with the state to
.achieve certification and expects that may occur late this year. The requirement for a
certified housing element applies to general law and charter cities.
Funding
SANDA Gfunding. Funds contingent upon a certified element are allocated by SANDAG and
the State Department of Housing and Community Development (HCD). Per SANDAG Board
Policy 33, adopted 2005, the agency will not award any discretionary funding� unless cities
meet these three policy criteria:
1. Have a certified housing element;
2, Can show progress'in making any land use changes required by the certified element
(e.g., rezoning property to a higher density), and;
3 Report annually the progress in providing housing to the four different income
categories (Carlsbad does this).
Attachment I identifies,fandina subject to Policy 33), Attachment 2 lists funding not requiring ions made directly by Caltrans
a certified, element. This funding includes, for example, all6citl
to local daencies and allocations not'iwarded on a competitive basis,
SANDAG staff estimates that programs subject to Policy 3' ) will yield about S 12 to 14
million- annually in potential grants over the next few funding cycles (FY 2009 and beyond).
About half this amount consists of funding from the Smart Growth Incentive Program, a
fairly new . funding source for which Carlsbad has not applied since it lacks a certified
element, The rpinaining funding is from the TDA and TransNet programs from which
Carlsbad regularly has received money in the past.
It is difficult to estimate the funds Carlsbad would receive from programs subject to Policy,
33 because of the competitive nature of the programs. However, from FY 1998-2006, the
City received a total of $1,63 ) 6,682 in TDA and TransNet funding (excluding for the Coastal
Rail Trail), which equates to an ayerage of roughly S234,000 for.each of the seven fiscal
years funding was awarded.

Attachment 3 provides a further breakdown of the above information and also identifies a
project potentially eligible for TDA. and TransNet funds, subject to Board Policy 33.
HCD funding. With a certified housing element, Carlsbad would also be eligible to apply for
the 'Workforce Housing Grant and In -Fill Development Grant, both competitive funding
programs administered by HCD. Previously, Carlsbad has received $450,000 from• the
Workforce Housing Grant.
Without a certified element -since mid-2005, staff estimates the City has missed out on about
S 1.8 million from these grants, although exact numbers are difficult to predict since grants
amcompetitive. In succeeding years, it,is estimated that Carlsbad would potentially miss out
on about S 1,000,000 annually from these grants. Once again, this is only a rough estimate.
due to competition.
Land Use Authority
State certification of a housing element provides a local jurisdiction with a rebutable
presumption that the housing element is legally valid. Thus, challenges brought a-ainst a
certified element shifts the burden of proof to show that it is inadequate to the challenger,
Without a certified housing element, the City is vulnerable to challenges that its General Plan
is inadequate or incomplete. Case law has established that a finding of consistency with a
General Plan is not valid where a general plan is incomplete or inadequate. Since many land
use decisions iequire a finding -of general plan consistency, a defective housing. element may
prevent Carlsbad from approving tentative subdivision maps or other land use applications.
Please let me know if I may answer any questions.
