Subject: Paleontological Assessment for the Vancouver Street Sewer Extension Project,
City ofCarlsbad, SanDiego County, California
Dear Mr. Biskup:
LSA Associates, Inc. (LSA) conducted a paleontological resources assessment for the Vancouver
Street Sewer Extension Project located in the City of Carlsbad (City), San Diego County (County),
California. Specifically, the proposed project is located along a portion of Vancouver Street and a
portion of Via De Canto, and also passes through Hidden Canyon Community Park. This assessment
included a geologic analysis, a locality search at the San Diego Natural History Museum (SDNHM), a
field survey, and this letter. The purpose of the assessment was to determine whether paleontological
resources may be present within the proposed project area, whether they might be impacted by
development ofthe project, and to make recommendations to mitigate any potential impacts to
paleontological resources.
Project Description
The City proposes to extend an existing sewer line from a segment of Vancouver Street to Via de
Canto within the City (see Figure 1, Project Location Map, and Figure 2, Project Footprint; all figures
attached). The proposed gravity flow sewer will allow for the removal of an existing sewer lift
station. The gravity system will provide a more reliable system of conveying wastewater, reducing
spill risks, and eliminating energy consumption required for operating the pumps at the existing lift
stafion. The 10.75-inch outside diameter (8-inch inside diameter) high-density polyethylene (HDPE)
sewer pipe has an overall length of 1,543 linear feet.
Approximately 600 feet (ft) of the pipeline will be installed using an open trench with depths varying
up to 19 ft but averaging between 6 to 8 ft below the existing ground surface. The open trench portion
will be within a public right-of-way on Vancouver Street and through the adjacent Hidden Canyon
Community Park. The remaining 943 ft of pipeline will be installed using horizontal slant drilling
(a.k.a. horizontal directional drilling, HDD) techniques through open space and passive recreational
areas (including portions of Hidden Canyon Park). The HDD technique utilizes drilling mud (slurry,
bentonite), which will be contained and controlled pursuant to a City-approved Drilling Mud Control
Plan. Staging areas for equipment will be located within the roadway on Vancouver Street. Segments
of pipe will be laid out for on-site assembly (see Figure 2, Project Footprint) on existing paved
surfaces along Vancouver Street and the parking area for Hidden Canyon Park as well as a small
portion that will be laid out over ornamental vegetation associated with the park. A drill pit and exit
pit will be installed using typical pipeline excavation methods and equipment. Pit locations (for either

the drill pit or the exit pit) are situated outside of sensifive habitats on the roadway on Via de Canto
and in ornamental vegetation east of the park (as shown in Figure 2). The drilling and installation of
the HDD portion of the sewer pipe will occur approximately 8 to 65 ft below the ground surface.
Paleontological Sensitivity
Based on the paleontological resources that are or are not contained in the geologic formations in the
County, levels of paleontological resource potential and sensitivity have been developed by Demere
and Walsh (1993). In general, there are five paleontological resource potential and sensitivity ratings:
High, Moderate, Low, Marginal, and No Potential. These are described in more detail below:
• High. High resource potential and high sensitivity are assigned to geologic formations known to
contain paleontological localities with rare, well-preserved, critical fossil materials for
stratigraphic or paleoenvironmental interpretation, and fossils providing important information
about the paleoclimatic, paleobiological and/or evolutionary history (phylogeny) of animal and
plant groups. In general, formations with high resource potential are considered to have the
highest potential to produce unique invertebrate fossil assemblages or unique vertebrate fossil
remains and are, therefore, highly sensitive.
• Moderate. Moderate resource potential and moderate sensitivity are assigned to geologic
formations known to contain paleontological localities. These geologic formations are judged to
have a strong, but often unproven, potential for producing unique fossil remains (Demere and
Walsh 1993).
• Low. Low resource potential and low sensitivity are assigned to geologic formations that, based
on their relatively young age and/or high-energy depositional history, are judged unlikely to
produce unique fossil remains. Low resource potential formations rarely produce fossil remains
of scientific significance and are considered to have low sensitivity. However, when fossils are
found in these formations, they are often very significant additions to a geologic understanding of
the area.
• Marginal. Marginal resource potential and marginal sensitivity are assigned to geologic
formations that are composed either of volcaniclastic (derived from volcanic sources) or
metasedimentary rocks, but that nevertheless have a limited probability for producing fossils from
certain formations at localized outcrops. Organisms can have been fossilized by being covered by
ash, dust, mud, or other debris from volcanoes. Sedimentary rocks can have been metamorphosed
by heat and/or pressure caused by volcanoes or plutons. If these sedimentary rocks had
paleontological resources within them, the resources may have survived the metamorphism and
may still be identifiable within the metasedimentary rock. These formations are marginally
sensitive.
• No Potential. No resource potential is assigned to geologic formations that are composed entirely
of volcanic or plutonic igneous rock, such as basalt or granite, and therefore do not have any
potential for producing fossil remains. These formations have no paleontological resource
potential, i.e., they are not sensitive.

Geology
The project area is located within the Coastal Plains Region of the Peninsular Ranges Geomorphic
Province. The Peninsular Ranges are a 900-mile (mi) long northwest-southeast-trending structural
block that extends from the tip of Baja California to the Transverse Ranges in Los Angeles County
(Norris and Webb, 1976). The total width of the province is approximately 225 mi, with a maximum
landbound width of 65 mi (Sharp, 1976). This region is characterized by a series of northwest-
trending mountain ranges separated by northwest-trending valleys, subparallel to faults branching
from the San Andreas Fault. The trend of topography is similar to that of the Sierra Nevada, with
granitic rock intmding on the older metamorphic rocks. The Province contains extensive pre-
Cretaceous (>65 million years ago) igneous and metamorphic rocks covered by limited exposures of
post-Cretaceous sedimentary deposits.
The Coastal Plains region lies between the Pacific Ocean on the west and the foothills of the
Peninsular Ranges to the east. The Coastal Plains consist of layered sedimentary sequences deposited
over Mesozoic plutonic crystalline basement rocks of the Peninsular Ranges Batholith as well as
Mesozoic volcanic and metamorphic rocks. The sedimentary rocks of the Coastal Plains region range
in age from the late Cretaceous (approximately 80 million years old) Lusardi Formation to
Quaternary stream deposits. However, the dominant rocks of the Coastal Plains consist of Eocene
marine transgressive and regressive sequences deposited within the ancient San Diego Embayment.
Geologic mapping by Kennedy and Tan (2005) indicates that the entire project footprint is underlain
by exposures of the middle Eocene (48 to 40 million years ago) Santiago Formation. The geology of
the project area and vicinity is depicted on Figure 3. The Santiago Formation is described in more
detail below.
Santiago Formation. The middle Eocene Santiago Formation was first named Woodring and
Popenoe (1945) for Eocene deposits located within the northwestern Santa Ana Mountains in
Orange County. The Santiago Formation is composed of marine to nonmarine sediments up to
2,690 ft thick in the Santa Ana Mountains. It conformably overlies the Silverado Formation and is
in turn conformably overlain by the Undifferentiated Sespe/Vaqueros Formation. Within San
Diego County, the lower part of the Santiago Formation interfingers with the Delmar Formation
and Torrey Sandstone in the Encinitas quadrangle (Kennedy and Tan 2005).
This formation is often divided into three units, a lower unit: Member A, a middle unit:
Member B and an upper unit: Member C. In general, the lower portions of the Formation
appear to be marine in origin, while portions are nonmarine in origin (Morton et al., 1976 and
Schoellhamer et al, 1981). The Member A beds are light gray to yellowish gray, medium coarse-
grained friable sandstone. In some areas the basal portion of these beds is a conglomerate that is
up to 225 ft thick. The sandstone is arkosic, with essentially equal amounts of quartz and feldspar,
and minor biotite that increases toward the top of the unit. The gravels are primarily siliceous
plutonics and metavolcanics derived from the Peninsular Ranges. It is massive, broadly cross
bedded, and contains thin, discontinuous, lenticular lenses of greenish gray clay that are often
only tens of feet in lateral extent. Also present are lenses of fine siltstone and fine-grained, well-
bedded sandstone.
The Member B unit is not always present but when present consists of soft, medium-grained,
moderately well-sorted arkosic sandstone.
11/14/11 «P:\HCR1103A\Paleo\Paleo Assessment LetterVancouver Street Sewer Nov-201 l.doc»
LSA ASSOCIATES, INO.
The upper Member C beds are grayish yellow to white, friable, fine- to medium-grained
sandstone interbedded with reddish brown and greenish gray mottled sandy siltstone and
claystone and some small discontinuous lenses of pebbly conglomerate. The sandstone tends to
be poorly sorted, poorly bedded, and angular to subangular. Conglomerate clasts are well-
rounded red and green metavolcanics, light-colored plutonics, and sedimentary rocks.
Montmorillonite is the main clay mineral in the siltstone and claystone lenses with minor amounts
of kaolinite.
The geotechnical investigation of the project prepared by Ninyo & Moore (Ninyo & Moore, 2010)
contains information that the project is underlain by artificial fill and the Santiago Formation. Based
on the description of the boring logs that extended up to 61 ft beneath the surface. The Santiago
Formation will be encountered beneath the artificial fill beginning at 1 to 8 ft beneath the surface. The
geotechnical report stated that artificial fill materials were composed of clayey to silty sand that was
various shades of brown, moist and loose to medium dense. The geotechnical report also stated that
the Santiago Formation consisted of gray to brown, weakly to strongly cemented silty sandstone with
interbeds of moderately to strongly cemented siltstone. Some portions of the Santiago Formation
were so well cemented that the drilling rig could not drill through them.
Paleontology
A search of paleontological records housed in the Department of Paleontology at the SDNHM was
conducted on November 1, 2011 (Appendix C). The results indicate that there are 13 known
paleontological localities located within a 1-mile (mi) radius of the project; however none are located
within the project area. Four of these localities occur within unnamed Pleistocene (approximately
200,000 years old) alluvial and estuarine deposits. Recovered fossils include trace remains of marine
invertebrates (e.g., crabs, snails, clams, and pectens), marine vertebrates (e.g., sharks), and terrestrial
vertebrates (e.g., turkeys, horses, bison, deer, and camels). Nine localities were found in the middle
Eocene (approximately 43 to 42 million years ago) Santiago Formation, Member C in fluvial,
lagoonal, and marine deposits. These nine localities produced impressions of seeds (e.g., flowering
plants), trace remains of marine invertebrates (e.g., burrow infillings), shell remains and impressions
of marine invertebrates (e.g., foraminifera, snails, clams, oysters, ostracods, and crabs), mineralized
remains of marine vertebrates (e.g., sharks, fish), and mineralized bone of terrestrial vertebrates (e.g.,
amphibians, soft-shelled turtles, tortoises, crocodiles, lizards, and marsupials, insectivores, bats,
rodents, carnivores, primates, tapirs, rhino relatives, and oreodonts). The closest known locality
within the Santiago Formation is located approximately 0.6 mi away.
The SDNHM believes that the Santiago Formation has a known high paleontological sensitivity in the
County (Demere and Walsh, 1993). In addition, because of the known fossil occurrences in the
immediate project area, the SDNHM recommends that any proposed excavation activities that extend
deep enough to encounter previously undisturbed deposits of the Santiago Formation have the
potential to cause impacts to paleontological resources preserved in these deposits, and that a
paleontological resource mitigation program be developed for this project for ground-disturbing
activities associated with this project.

Survey
A survey of the project area was conducted on November 2, 2011, by Elizabeth Davidson. Most of
the project area where ground disturbance is proposed is developed and contains asphalt paving and
ornamental landscaping. What sediment was visible within the surface of the project area appeared to
be artificial fill, which is consistent with the geotechnical report. However, some of the native
sediments that outcrop on adjacent hillsides near the southem portion of the project at Via De Canto
were consistent with being from the Santiago Formation, as they have been mapped. No
paleontological resources were observed during this survey.
Recommendations
Based on the known occurrence of significant paleontological resources within the Santiago
Formation, it is assigned a High paleontological potential and sensitivity rating. As such,
paleontological mitigation will be required on this project to mitigate impacts to paleontological
resources. Based on the geotechnical report (Ninyo & Moore, 2010), most portions of the project do
contain artificial fill, which does not have paleontological sensitivity or potential; however, in most
cases excavation will extend deep enough to contact the underlying Santiago Formation.
The portions of the project that will be installed using HDD techniques will not require
paleontological mitigation, as the sediments that are removed are usually not directly visible because
the sediments are ground up during the drilling process and pumped into a holding tank. Mitigation
will be required during excavation of the entry and exit pits associated with the HDD, as these pits do
allow the direct observation of excavated sediments, and excavation depths will likely extend beneath
the fill that was noted by Ninyo &Moore (2010). Excavation associated with installation of the
portion of the sewer line that will be installed via an open trench (see Figure 2) will also require
paleontological mitigation, as the proposed excavation depths will likely extend deeper than the 5 to
8 ft of fill noted by Ninyo & Moore (2010) in this area and contact the underlying Santiago
Formation.
In order to mitigate impacts to paleontological resources within the project area, LSA recommends
that a Paleontologist be contacted to develop a Paleontological Resources Impact Mitigation
Monitoring Plan (PRIMMP). The PRIMMP should include, but not be hmited to:
• Attendance at the pregrade meeting by a qualified paleontologist or representative. At this
meeting, the paleontologist will explain the likelihood for encountering paleontological resources,
what resources may be discovered, and the methods of recovery that will be employed.
• Monitoring of excavation activities should be conducted by a qualified paleontological monitor in
areas identified as likely to contain paleontological resources. The monitor should be equipped to
salvage fossils and/or matrix samples as they are unearthed in order to avoid construction delays.
The monitor must be empowered to temporarily halt or divert equipment in the area of the find in
order to allow removal of abundant or large specimens. Monitoring should initially occur on a
full-time basis in areas identified as likely to have paleontological resources. Monitoring may be
reduced to a part-time basis if no resources are being discovered (monitoring reductions and when
they occur will be determined by a qualified paleontologist).

LSA ASSOCIATES, INC.
• Localized concentrations of small (or micro-) vertebrates may be found in on-site deposits.
Therefore, it is recommended that these sediments occasionally be spot-screened through Ys- to
Veo-inch mesh screens to determine whether microfossils are present. If microfossils are
encountered, additional sediment samples (up to 6,000 pounds, or 3 cubic yards) shall be
collected and processed through Vzo-inch mesh screens to recover additional fossils.
• Recovered specimens shall be prepared to a point of identification and permanent preservation.
This includes the washing and picking of mass samples to recover small invertebrate and
vertebrate fossils, the removal of surplus sediment from around larger specimens to reduce the
volume of storage for the repository and the storage cost, and the addition of approved chemical
hardeners/stabilizers to fragile specimens.
• Specimens shall be identified and curated in a museum repository with permanent, retrievable
storage. The repository institutions usually charge a one-time fee based on volume, so removing
surplus sediment is important. The repository institution may be a local museum or university
with a curator who can retrieve the specimens on request. A curation agreement with the
repository facility should be initiated prior to the beginning of excavation activities.
• A report of findings shall be prepared with an appended, itemized inventory of specimens. When
submitted to the Lead Agency, the report and inventory will signify completion of the program to
mitigate impacts to paleontological resources.

RE: Paleontological mitigation; Vancouver Street Sewer Project
Dear Mr. Smith:
This letter presents the results of a paleontological record search conducted for the
Vancouver Street Sewer project. The sewer project alignment is approximately 0.5 miles in
length and is located within the northern portion of the City of Carlsbad in the County of San
Diego. The sewer project is approximately 1/3 of a mile south of State Route 78 and 1/3 of a
mile east of El Camino Real. This alignment extends along Vancouver Street northwest ofthe
intersection with Concord Street. The sewer line then continues south from Vancouver Street
into the canyon to the south, 500 feet north of Carlsbad Village Drive. Published geological
reports (Kennedy and Tan, 2005) that cover the entirety of the project reveal that the proposed
project is located in areas underlain by the Middle Eocene-age (approximately 38 to 49 million
years old) Santiago Formation.
Site records housed in the Department of Paleontology at the San Diego Natural History
Museum document thirteen recorded fossil collecting localities within a one-mile radius of the
project site (see attached map and abbreviated locality descriptions). Four of these localities
occur within unnamed alluvial and estuarine deposits of Pleistocene-age (approximately 200
thousand years old). Recovered fossils include trace remains of marine invertebrates (e.g., crabs,
snails, clams, and pectens), marine vertebrates (e.g., sharks), and terrestrial vertebrates (e.g.,
turkeys, horses, bison, deer, and camels). Nine localities were found in the fluvial, lagoonal, and
marine deposits of the Santiago Formation, Member C. These localities produced impressions of
seeds (e.g., flowering plants), trace remains of marine invertebrates (e.g., burrow infillings), shell
remains and impressions of marine invertebrates (e.g., foraminifera, snails, clams, oysters,
ostracods, and crabs), mineralized remains of marine vertebrates (e.g., sharks, fish), and
mineralized bone of terrestrial vertebrates (e.g., amphibians, soft-shelled turtles, tortoises,
crocodiles, lizards, and marsupials, insectivores, bats, rodents, carnivores, primates, tapirs, rhino-
relatives, and oreodonts).
Given the known high paleontological sensitivity of the Santiago Formation in San Diego
County (Demere and Walsh, 1993) and proven fossil occurrences in the immediate project area,
it is suggested that any proposed excavation activities that extend deep enough to encounter
previously undisturbed deposits of the Santiago Formation have the potential to cause impacts to
paleontological resources preserved in these deposits. Furthermore, Demere and Walsh (1993)
Post Office Box 121390 • San Diego, California 92112-1390 * Telephone 619-255-0309 * FAX 619-255-0187 * www.sdnhm.org
have assigned the unnamed river terrace deposits to have a moderate sensitivity. Although this
unit is not mapped by Kennedy and Tan (2005) in the vicinity of the project, numerous outcrops
of non-marine Pleistocene deposits exposed along the 78 corridor suggest there is a potential to
encounter this unit. For the reasons described above, implementation of a complete
paleontological resource mitigation program during construction is recommended.
The information contained within this paleontological record search should be considered
private and is the sole property of the San Diego Natural History Museum. Any use or
reprocessing of information contained within this document beyond the scope of the Vancouver
Street Sewer project is prohibited.
If you have any questions concerning these findings please feel free to contact me at 619-
