Thank you for submitting an Early Assessment for the replacement of approximately 1,850 lineal feet of
eroded 21" concrete water pipeline with new 18" diameter steel pipeline and replacement of the
existing pressure sustaining facility located along Pirigos Way in the City of Oceanside. The water
pipeline replacement project would be constructed along the entire length of the roadway and would
also extend to the west, slightly across the border of Carlsbad, and east across Cannon Road, entirely
within the CMWD easement areas.
In response to your application, the Planning Division has prepared this comment letter. Please note
that the purpose of an Early Assessment is to provide you with direction and comments on the overall
concept of your project. This Early Assessment does not represent an in-depth analysis of your
project. It is intended to give you feedback on critical issues based upon the information provided in
your submittal. This review is based upon the plans. policies. and standards in effect as of the date of
this review. Please be aware that at the time of a formal application submittal. new plans. policies.
and standards may be in effect and additional issues of concern may be raised through a more specific
and detailed review.
Planning:
General
1. Please show the border between Carlsbad and Oceanside on the plans and on the title sheet
location map.
2. Please contact the City of Oceanside to determine if permits are required for the water pipeline
replacement project.
3. The title page of the final plans should be revised to show the name of the current or acting
Executive (City) Manager.
4. Please contact the Lake Calavera Preserve Manager prior to the commencement of any
construction activities in or adjacent to the preserve area. Include the following contact
information on the plans:

Environmental
1. The project is Phase 1 of the Water Supply and Transmission Project No. 48 for the replacement
or rehabilitation of the Tri-Agencies Water Pipeline (TAP). The potential environmental impacts
of this project were analyzed under EIR 12-01-City of Carlsbad Sewer Master Plan Master Plan
and CMWD Water and Recycled Water Master Plan Updates Final Program EIR.
Although this phase of the project occurs entirely within roadways and disturbed easement
areas, the west end of the project occurs within an easement along the east side of the lake
Calavera Preserve. The easement is immediately adjacent to sensitive habitat areas and/or
habitat potentially suitable for special status species.
The east end of the project appears to end near an open space area in Oceanside. If this area
contains native plants, a biologist must be retained to survey the area.
2. The EIR identified that, within certain portions of the project, construction activities and/or
construction noise could result in potential indirect impacts to special status species or sensitive
habitat areas. Therefore, the project is required to implement the following Mitigation
Measures:
Bio-lE Pre-Construction Biological Resource Surveys. Prior to construction of CIP projects or
portions of projects that will occur within disturbed or developed land, but will be sited
immediately adjacent to an undeveloped open space area (i.e., an area supporting naturalized
habitat, sensitive habitat; and/or habitat potentially suitable for special status species), the City
and CMWD shall retain a qualified biologist to perform a pre-construction survey to verify
existing biological resources adjacent to the project construction areas. The City and CMWD
shall provide the biologist with a copy of the CIP project plans that clearly depict the
construction work limits, including construction staging and storage areas, in order to determine
which specific portion(s) of the project will require inspection of adjacent open space areas
during the pre-construction survey. At minimum, the biologist shall perform a visual inspection
of the adjacent open space area in order to characterize the existing habitat types and
determine the likelihood .for special status species to occur, including the coastal California
gnatcatcher, migratory songbirds, and other bird species with the potential to breed in the area.
The pre-construction survey results shall be submitted to the City and CMWD prior to
construction in order to verify the need for the additional construction measures proposed
within Bio-1F through Bio-11 below.
Bio-lF Orange Construction Fencing. If it is confirmed through the implementation of
mitigation measure Bio-1E that the CIP project would occur immediately adjacent to sensitive
habitat areas and/or habitat potentially suitable for special status species, the City and CMWD
shall retain a qualified biologist to supervise the installation of temporary orange construction
fencing, which clearly delineates the edge of the approved limits of grading and clearing, and
the edges of environmentally sensitive areas that occur beyond the approved limits. This fencing

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. If work
occurs beyond the fenced or demarcated limits of impact, all work shall cease until the problem
has been remedied and mitigation identified. Temporary orange fencing shall be removed upon
completion of construction of the project. Implementation of this measure shall be verified by
the City prior to and concurrent with construction.
Bio-lG Construction-Related Noise. Construction noise created during the general· breeding
season (January 15 to September 15) that could affect the breeding of the coastal California
gnatcatcher, migratory songbirds, and other bird species associated with adjacent undeveloped
areas shall be avoided. No loud construction noise (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 general breeding season (January 15 through September 15).
If it is confirmed through the implementation of mitigation measure Bio-1E that the CIP project
could result in construction-related noise impacts to breeding birds during the general breeding
season, the City and CMWD shall retain a qualified biologist to monitor the construction
operations. The biological monitor shall be present to monitor construction activities that occur
adjacent to the undeveloped open space area potentially supporting breeding birds. The
monitor shall verify that construction noise levels do not exceed 60 dBA hourly average and
shall have the ability to halt construction work, if necessary, and confer with the City, USFWS,
and CDFG to ensure the proper implementation of additional protection measures during
construction. The biologist shall report any violation to the USFWS and/or CDFG within 24 hours
of its occurrence.
Bio-lH Construction Staging Areas. If it is confirmed through the implementation of mitigation
measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas
and/or habitat potentially suitable for special status species, the City and CMWD shall design
final CIP project construction staging areas such that no staging areas shall be located )Nithin
sensitive habitat areas. The construction contractor shall receive approval by the City Planning &
Engineering Divisions prior to mobilizations and staging of equipment outside of the project
boundaries.
Bio-11 Contractor Training. If it is confirmed through the implementation of mitigation
measure Bio-1E that the CIP project would occur immediately adjacent to sensitive habitat areas
and/or habitat potentially suitable for special status species, the City and CMWD shall retain a
qualified biologist to attend pre-construction meetings to inform construction crews of the
sensitive resources and associated avoidance and/or minimization requirements.
