LCWD finds that the project will not have a significant adverse effect on the environment based on
the results of the Initial Study/Environmental Checklist (see Section 4) and the Environmental
Evaluation Discussion (see Section 5, Discussion of Environmental Imyacrs). Measures have been
incorporated into the project to ensure that any impacts w;ll be less than significant. A Mitigated
Negative Declaration is therefore proposed to satisfy the requirements of CEOA (PRC 21000 et. seq.
14 Cal Code Kegs 15000 et. seq.). This conclusion is supported by the following:
3.1 NO SIGNIFICANT EFFECT FINDING
1. Land Use: The proposed project would be compatible with the existing and surrounding
land uses adjacent to the project site. Measures have been incorporated into the project
design to reduce potentialimpacts associatedwithnoise from the proposed standby generator
and wetland disturbance (see Section 3.2, Mitigation Measures and Monitoring Pro_eranz, and
Section 5.4, Land Use and Planning).
2. Population and Housing: The capacity of the existing station is not being increased,
therefore the proposed project would not generate additional population, and the approval
of the project would have a less than significant effect on human population and housing (see
discussion under Section 5.2, Popularion and Housing).
3. Geologic Problems: No long-term geologic problems would occur with implementation of
measures recommended as a part of the geotechnical investigation conducted for the project
(see discussion under Section 3.2, Mitigation Measures andMonitoring Program, and Section 5.3,
Geologic Problems). . .
4. Water: No long-term adverse impact to local waters is anticipated as a result of this project.
Measures are incorporated into the project which reduce project effects associated with
potential discharge of sediments and dewatering activities into the Batiquitos Lagoon to less
than significant (see Section 3.2, Mitigation Measures and M&toring Program, as well as the
discussion under Section 5.4, Water).

Air Quality: Measures are incorporated into the project which reduce effects associated
with generation of particulate matter less than 10 microns (PM,,) and emissions from the
standby generator to less than significant (see Section 3.2, A&igationkkzs~ns andMoniroring
Program as well as the discussion under Section 5.5, Air Quakry,I.
Transportation and Circulation: It is not anticipated that construction of the project
would affect vehicle, bicycle or pedestrian traffic on La Costa Avenue. The first phase of
construction would involve the clearing of the vehicle turnout area. Following completion
of the turnout, construction equipment for the access road and miscellaneous equipment
placement will be stored within the turnout area. No construction equipment would operate
or be stored within the La Costa Avenue right-of-way.
Biological Resources: Measures are incorporated into the project to mitigate direct impacts
to biological resources associated with grading for the maintenance access road and
turnaround area. Measures are also incorporated into the project which reduce indirect
biological resource impacts associated with construction adjacent to the Batiquitos Lagoon
and potential noise impacts associated with the standby generator (see Section 3.2, Mitigmion
Measures and Monitoring Program, as well as the discussion under Section 5.7, Biological
Resources).
Energy and Mineral Resources: The proposed project’s long-term usage of diesel fuel in
association with the standby generator is not anticipated to exceed the use and demand
anticipated by SDG&E. (see discussion under Section 5.8, Energy andMincrulResources).
Hazards: Observance of standard safety measures during construction and operation/
maintenance will reduce the risk of explosion or release of hazardous substances to a less than
significant level. Traffic control measures incorporated into the project construction process
reduce potential hazards to pedestrian and bicyclists (see discussion under Sections 3.2,
Mitigation Measures andMonitoring Program, and 5.9, Hazards).
Noise: Measures are incorporated into the project which reduce noise impacts associated
with construction activities to less than significant. Measures have been incorporated into
the design of the proposed standby generator to avoid potential noise impacts to surrounding
residences and sensitive wildlife species (see Section 3.2, Mitigation Mcaiures andMonitoring
Program, as well as the discussion under Section 5. IO, Noise).

Saxony Pump Station Rehabilitation Pmject
11. Public Services: The proposed project does not involve any new residents, and would not
generate a demand for public services; therefore, no impact to public services would occur (see
discussion under Section 5.1 I, Public Setvices).
12. Utilities and Service Systems: Existing capacity of the station will not be increased,
therefore implementation of the project would not involve a demand for new services and
utilities other than those constructed. The project design proposes undergrounding of
existing telephone and electrical utilities located within the area proposed for the access road
and SDG&E’s quitclaim of their easement (see dkussion under Sccrion 5.42, Utilities and
Service Systems).
13. Aesthetics: Existing pump station facilities would be placed underground as a part of the
project with the exception of two enclosures. Considering the proximity to the roadway, the
enclosures and access road are considered to be a visual extension of La Costa Avenue.
Therefore, no impacts to aesthetics would result from the proposed project (see discussion
under Section 5.43, Aesthetics).
14. Cultural Resources: There is a potential for cultural resources to be located in the area to
be disturbed in association with project implementation. Based on a paleontological analysis
completed for the La Costa Road Widening project, geological formations underlying the
project vicinity include the Santiago Formation, De1 Mar Formation, and Pleistocene marine
terrace deposits. Paleontological resource potential within these formations is considered to
be high. Measures have been incorporated into the proposed project to reduce potential
impacts to cultural and paleontological resources to less than significant (see Section 3.2,
Mitigation Measures and Monitoring Program, and discussion under Section 5.44, Culturul
Resources).
15. Recreation: Implementation of the project would not affect existing or planned recreational
facilities (see Section 3.2 and discussion under Section 5.15, Recreation).
3.2 MI-IlGA-flON MEASURES AND MONlTORlNG PROGRAM
LCWD has summarized here the various requirements imposed on the project to reduce impacts to
less than significant:

Saxony Pump Station Rehabilitation Proiect
Land Use and Planning: To comply with the City of Carlsbad’s LCP, the folIowing measures will
be incorporated into the project:
. Prior to construction, LCWD shall obtain a Coastal Development Permit from the City of
Carlsbad.
. Wetlands iinpact mitigation shall be a condition of the permit. As discussed in Section 5.7,
Biological Resources, LCWD will mitigate for impacts to wetlands.
. An established mitigation area adjoins the project site to the north. The construction plans
shall state that the Contractor for the proposed project will not disturb any areas outside of
the work area. Therefore, there wilI be no grading, landscaping or other disturbance within
the mitigation area.
In addition, measures required to reduce potential impacts from standby generator noise (See Noise,
below) and direct impacts to wetlands (see Biological Resources, below) will reduce identified
inconsistencies with the environmental goals of the relevant land use plans to below a level of
significance.
Geologic Problems:
. Plans and specifications for the proposed project shall incorporate standard geoteclmical
recommendations as presented in the AGRA Geotechnical Report. Measures are
recommended in the areas of site preparation and grading, slabs on grade, retaining walls,
flexible pavement structural section, corrosion and geotechnical and construction review.
The complete AGRA investigation including the recommendations, is inchided as
Attachment A to this report.
. Erosion control measures, such as the use of sandbags, will be implemented to reduce
potential soil erosion during construction.
Water :
. Prior to construction, the Contractor shall obtain Order No. 96-41~NPDES Permit #919002
from the RWQCB for dewatering activities. (The official title of the permit to be obtained
is: General Waste Discharge Requirements for Groundwater and Similar Waste Discharges for Some

Construction and Remcdiation Projects to Su+cc Waters Within San Diego Region Except San Diego
Bay.) The permit may be conditioned to protect the water quality in the project vicinity.
These conditions may include treatment, discharge sampling, monitoring and reporting.
Air Quality:
. LCWD will require, as part of the construction documents, measures to reduce PM,, dust
emissions inciuding the use of watering and other dust control measures during project
construction.
. The Contractor shall obtain a Certificate of Registration from the SDAPCD for operation of
the standby generator to ensure that emissions do not result in adverse impacts to ambient
air quality.
Biological Resources:
. Prior to construction, impacts to 0.04 acre of coastal sage scrub will be mitigated by the
acquisition (by LCWD) of 0.08 acre of coastal sage scrub within an approved mitigation bank
or planned open space (preserve) area. If not previously encumbered, appropriate easements
guaranteeing permanent preservation wiU be obtained.
. Prior to construction, LCWD will devise a revegetation plan and revegetate 0.42 acre of
southern willow scrub/mule fat scrub located offsite which is similar in species richness and
structure to that removed. LCWD will devise a Concept Plan which will inciude: 1) the
location of the project, 2) applicant responsibilities, 3) revegetation contractor responsibilities,
4) ownership status and, 5) present and proposed uses of the mitigation area. LCWD wilJ
also devise an Implementation Plan which will include: 1) timing of construction activities,
2) timing of revegetation effort, 3) revegetationmateriais, 4) site preparation, 5) planting plan
and, 6) irrigation plan. A Maintenance Plan will also be devised by LCWD. Prior to
construction these plans will be reviewed and approved by local resource agencies including
the California Department of Fish and Game. This revegetation effort will be subject to a 5
year moriitoring period and performance criteria as dictated in the revegetation plan.
. To reduce the generator noise to a one-our average noise level of 60 dB or less at the adjacent
biological habitat area, a minimum six-foot high noise barrier will be designed by a qualified
acoustician and constructed along the north side of the generator. The barrier should be

aligned so as to connect to the east and west side retaining walls. Due to access
requirements, the barrier cannot be constructed of masonry material, therefore, it is
recommended that tongue and groove boards with a minimum thickness of 3/4-inch be used
as a barrier material. Also, a sound absorbing material such as Pyrock Acoustement 40 (with
a minimum thickness of l-5/8 inches) or equivalent, should be applied to the interior surfaces
of the retaining wall.
. Construction will not occur during the breeding seasons of three bird species (California
gnatcatcher February 15 through August 15; least Bell’s Vireo April 1 through July 31; and
southwestern willow 5ycatcher May 22 through July 31). If construction must occur during
the breeding season, weekly surveys must be conducted by a qualified biologist to determine
the presence/absence of the potentially affected species. If one or more of the species is
detected, construction must stop until noise levels can be demonstrably reduced to a level
below 60 dB.
Hazards:
. Measures incorporated for Transportation above (see56a through5.6-e) reduce construction
impacts to emergency routes to a level below significance.
Noise:
. The hours of construction shah be restricted to 7AM to sunset Monday through Friday, and
8AM to sunset on Saturdays. An exemption to construction outside these times shall be
required for activities which extend beyond these times.
Cultural/Paleontological Resources:
. A qualified paleontological monitor (certified by the County of San Diego) will be present
during open excavation activities. LCWD will also contract with a qualified archaeologist
(certified by the County of SanDiego) to conduct monitoring during construction activities.
. If any paleontological or cultural resources are discovered during construction, grading would
be temporarily delayed to allow for recovery of these resources.
