(Rincon) was retained by Foxlin Architects to conduct a paleontological resource assessment for the Resort View Project (project) in the City of Carlsbad (City), San Diego County, California. The goal of the assessment is to identify the geologic units that may be impacted by development of the project, determine the paleontological sensitivity of geologic units within the project site, assess potential for impacts to paleontological resources from development of the project, and recommend mitigation measures to avoid or mitigate impacts to scientifically significant paleontological resources, as necessary. Figures are provided in Attachment A. This paleontological resource assessment has been prepared to support environmental review under the California Environmental Quality Act (CEQA). The City is the CEQA Lead Agency for the project. Project Location and Description The 0.86-acre (37,461 square feet) project site is located in the City of Carlsbad along Viejo Castilla Way, south of Navarra Drive and west of Pirineos Way (Attachment A, Figure l}. The project site is adjacent to existing multi-family residences to the north and west, and adjacent to a portion of the La Costa Golf Course to the south (Attachment A, Figure 2). The project site consists of two parcels: Assessor's Parcel Numbers (APN) 216-170-1500 and 216-170-1400. Both parcels are currently undeveloped. The project includes the construction of 26 residential units in five separate residential buildings. Two buildings on the southern portion of the project site adjacent to the La Costa Golf Course would each be three stories, with three townhome units each and a floor area of 6,882 to 6,801 square feet. The two central buildings would each consist of six units and would have 9,230 to 9,274 square feet of floor area. The two central buildings would have three levels of living over one level of parking and amenity space, which includes a proposed gym and lobby. The fifth building would Environmental Scientists Planners Engineers r \ r Foxlin Architects Resort View Project be located in the northern area of the project site. This building would have 10,323 square feet of floor area and would consist of four 1-bedroom, one 2-bedroom, and three 3-bedroom units. Vehicular access to the site would be through two driveways off Viejo Castilla Way that would provide access to the garages and parking spaces under each of the buildings. There would be a total of 48 parking spaces; 36 spaces within garages and 12 covered spaces, which would include one accessible space compliant with the Americans with Disabilities Act (ADA). Regulatory Setting Fossils are remains of ancient, commonly extinct organisms and, as such, are nonrenewable resources. The fossil record is a document of the evolutionary history of life on earth, and fossils can be used to understand evolutionary pattern and process, rates of evolutionary change, past environmental conditions, and the relationships among modern species (i.e., systematics). The fossil record is a valuable scientific and educational resource, and individual fossils are afforded protection under federal, state, and local environmental laws, where applicable. California Environmental Quality Act Paleontological resources are protected under CEQA, which states, in part, that a project will "normally" have a significant effect on the environment if it, among other things, will disrupt or adversely affect a paleontological site except as part of a scientific study. Specifically, in Section V(c) of Appendix G of the State CEQA Guidelines, the Environmental Checklist Form, the question is posed, "Will the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature." To determine the uniqueness of a given paleontological resource, it must first be identified or recovered (i.e., salvaged). Therefore, mitigation of adverse impacts, to the extent practicable, to paleontological resources is mandated by CEQA. CEQA does not define "a unique paleontological resource or site." However, the Society of Vertebrate Paleontology (SVP) has defined a "significant paleontological resource" in the context of environmental review. The SVP defines a Significant Paleontological Resources as: ... fossils and fossiliferous deposits, here defined as consisting of identifiable vertebrate fossils, large or small, uncommon invertebrate, plant, and trace fossils, and other data that provide taphonomic, taxonomic, phylogenetic, paleoecologic, stratigraphic, and/or biochronologic information. Paleontological resources are typically to be older than recorded human history and/or older than middle Holocene (i.e., older than about 5,000 radiocarbon years). The loss of paleontological resources that meet the criteria outlined above (i.e., a significant paleontological resource) would be a significant impact under CEQA, and the CEQA lead agency is responsible for ensuring that impacts to paleontological resources are mitigated, where practicable, in compliance with CEQA and other applicable statutes. California Public Resources Code Section 5097.5 of the Public Resources Code (PRC) states: Page2 ( ,.... \. r Foxlin Architects Resort View Project No person shall knowingly and willfully excavate upon, or remove, destroy, injure or deface any historic or prehistoric ruins, burial grounds, archaeological or vertebrate paleontological site, including fossilized footprints, inscriptions made by human agency, or any other archaeological, paleontological or historical feature, situated on public lands, except with the express permission of the public agency having jurisdiction over such lands. Violation of this section is a misdemeanor. As used in this PRC section, "public lands" means lands owned by, or under the jurisdiction of, the state or any city, county, district, authority, or public corporation, or any agency thereof. Consequently, public agencies are required to comply with PRC 5097.5 for their own activities, including construction and maintenance, as well as for permit actions (e.g., encroachment permits) undertaken by others. City of Carlsbad The City of Carlsbad General Plan does not have specific requirements for paleontological resources; however, the City sets forth specific paleontological mitigation policy in Chapter 10 of the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (City of Carlsbad 2017). The guidelines provide mitigation requirements, including paleontological sensitivity assessment, records search and literature review, field survey, preparation of a Paleontological Mitigation and Monitoring Plan, construction monitoring, and curation. The City guidelines are provided below: • 10.1. Sensitivity Model Review. In reviewing the paleontology sensitivity map, the City shall first determine whether or not the project is located in a medium or high sensitivity area, which will require a paleontological survey. Projects located entirely within low sensitivity areas require no further study for paleontology; however, the result of the sensitivity model check shall be reported in the CEQA document and, at minimum, a standard mitigation measure for unanticipated discovery shall apply to all non-exempt projects (described further below). • 10.2. Records Searches and Literature Reviews. The San Diego Natural History Museum (SDNHM) is the sole institution holding fossils for San Diego County, and therefore, represents the best source for information about fossil-bearing sediments and rock. For projects that require a paleontological survey, the City or qualified consultant shall first request a paleontological assessment from the SDNHM for the project area plus a one-mile radius. Other sources that may be reviewed include on line paleontology databases, the published literature, and project or nearby geotechnical boring reports to obtain information on subsurface rock unit depths. • 10.3. Field Surveys. If the underlying geologic formation is exposed on the site, a field survey may be warranted. All paleontological field surveys for the project area must be completed by or under the direction of the Principal Paleontologist, who is responsible for ensuring that the surveyor is knowledgeable about local geology and paleontology. All paleontological resources encountered during the survey shall be documented on standard locality forms and documented with photography and GPS coordinates. The surveyor shall describe the sediments of the project in detail and evaluate the potential for specific sediments to be conducive to the preservation of fossils. Page3 C ( r Foxlin Architects Resort View Projed Only qualified, trained paleontologists with specific expertise in the type of fossils being evaluated can determine the scientific significance of paleontological resources. • 10.4. Impact Analyses and Mitigation Measures. If the survey resulted in a negative finding for paleontological resources, then the paleontology sensitivity model should be updated to reflect low sensitivity for that project area. The Principal Paleontologist shall determine whether or not, based on professional judgement, the designation of low sensitivity can be extended outside of the project area. In addition, the CEQA document shall require the adoption of a standard unanticipated discovery measure that instructs construction personnel to immediately halt ground-disturbing activity at the location of a suspected paleontological exposure plus a SO-foot radius around the find. Work shall be halted within the no-work radius until the City can consult with a qualified paleontologist on the identification and evaluation of the find. At the discretion of the Principal Paleontologist, an additional mitigation measure requiring contractor awareness training may be warranted. However, unlike the unanticipated discovery measure, this is not a default mitigation measure for all projects that result in a negative survey for paleontological resources. If the survey and/or Paleontological Assessment Report resulted in a positive finding for paleontologlcal resources or a high probability for fossil-bearing sediments below the surface, then a Principal Paleontologist shall be retained to prepare a Paleontological Mitigation and Monitoring Plan to address the following information, as applicable and appropriate: 0 The level of monitoring (spot checks, part time or full time), protocols and authorization for work stoppages, and safety procedures 0 The need for Contractor Awareness Training for all earthmoving personnel for any projects where a monitor will not be present full time 0 A research design listing the research questions and the data requirements for those questions 0 The level and type of assistance from the contractor needed by the paleontologist to take bulk samples and place them into a safe area for processing 0 The methods for fossil collection, fossil preparation, fossil identification, stratigraphic profiles, and curation 0 The types of progress reports that will be provided to the project proponent and City (weekly or monthly) 0 The schedule for reporting 0 A recommendation for the updating of the paleontology sensitivity model, which takes into consideration the presence or absence of paleontological resources, the amount of ground disturbance, and the potential for future discoveries 0 The identity of the financially-responsible party • 10.4.3 Preferred Treatment Options and Mitigation Measures. Vertebrate fossils are rare in contrast with invertebrate and plant fossils. Due to this factor, all vertebrate fossils are generally recovered while samples of invertebrates and plants are taken. Documentation and curation is the preferred treatment method for paleontological resources. Page4 c· r Foxlin Architects Resort View Project • 10.5 Curation. In accordance with the Paleontological Mitigation and Monitoring Plan, specimens of significant fossils, all paleontological data, and a copy of the final report shall be curated at the SDNHM. Methods Rincon evaluated the paleontological sensitivity of the geologic units that underlie the project site using the results of the paleontological locality search and review of existing information in the scientific literature concerning known fossils within those geologic units. Rincon submitted a request to the SDNHM Department of Paleontology for a list of known fossil localities from the project site and immediate vicinity (i.e., localities recorded on the USGS 7.5-minute Encinitas, CA quadrangle) and reviewed geologic maps and scientific literature. Following the records search and literature review, Rincon assigned a paleontological sensitivity to the geologic units on the project site. The potential for impacts to paleontological resources is based on the potential for ground disturbance to directly impact paleontologically sensitive geologic units. Field Survey A field survey of the project site was conducted on November 27, 2018. The purpose of the field survey was to inspect the ground surface visually for exposed fossils and to evaluate geologic exposures for their potential to contain preserved fossil material at the subsurface. Key Personnel This paleontological assessment was prepared under the direction of Rincon's Paleontology Program Manager, Jessica DeBusk, who provided quality assurance review of this report. Associate Paleontologist Heather Clifford was the primary author of this report. Rincon Staff Paleontologist Jorge Mendieta conducted the field survey. Ms. DeBusk has more than 16 years of professional experience as a consulting paleontologist and meets the SVP's definition of a qualified professional paleontologist. Paleontological Resource Potential The SVP (2010) has developed a system for assessing paleontological sensitivity and describes sedimentary rock units as having high, low, undetermined, or no potential for containing scientifically nonrenewable paleontological resources (see Table 1). This criterion is based on rock units in which significant fossils have been determined by previous studies to be present or likely to be present. The potential for impacts to paleontological resources is based on the potential for ground disturbance to directly impact paleontologically sensitive geologic units. Additionally, the County of San Diego has developed its own sensitivity (resource potential) classification scheme for paleontological resources. These categories include high, moderate, low, and marginal, and zero sensitivity, and are listed below in Table 1 (Demere and Walsh 1993; Stephenson et al. 2009). Pages r Foxlin Architects Resort View Project Table 1 SDNHM Paleontologlcal Sensitivity and SVP Resource Potential Categories SDNHM Paleontological Paleontolog1cal Sensitivity (Demere and Resource Potential Walsh 1993; Stephenson SVP (2010) Criteria and Mitigation Recommendations et al. 2009) No Potential N/A Low Potential N/A Undetermined Potential High Potential Rock units that are formed under or exposed to immense heat and pressure, such as high-grade metamorphic rocks and plutonic igneous rocks. No mitigation required. Marginal sensitivity is assigned to geologic formations that are composed either of pyroclastic volcanic rocks or metasedimentary rocks, but which nevertheless have a limited probability for producing fossil remains from certain sedimentary lithologies at localized outcrops. Mitigation is not typically required. No Sensitivity Marginal Sensitivity Rocks units that have yielded few fossils in the past, based upon review Low Sensitivity of available literature and museum collections records. Geologic units of low potential also include those that yield fossils only on rare occasion and under unusual circumstances. Mitigation is not typically required. Moderate sensitivity is assigned to geologic formations known to Moderate Sensitivity contain paleontological localities with moderately preserved, common elsewhere, or stratigraphically long ranging fossil material. The moderate sensitivity category is also applied to geologic formations that are judged to have a strong, but unproven potential for producing important fossil remains (e.g., pre-Holocene sedimentary rock units representing low to moderate energy, marine to non-marine depositional settings). Mitigation may be required. In some cases, available literature on a particular geologic unit will be N/A scarce and a determination of whether or not it is fossiliferous or potentially fossiliferous will be difficult to make. Under these circumstances, further study is needed to determine the unit's paleontological resource potential (i.e., field survey). A field survey is required to further assess the unit's paleontological potential. Geologic units with high potential for paleontological resources are High Sensitivity those that have proven to yield vertebrate or significant invertebrate, plant or trace fossils in the past or are likely to contain new vertebrate materials, traces, or trackways. Rock units with high potential also may include those that contain datable organic remains older than late Holocene (e.g., animal nests or middens). Typically, a field survey as well as onsite construction monitoring will be required. Any significant specimens discovered will need to be prepared, identified, and curated into a museum. A final report documenting the significance of the finds will also be required. Page 6 C r Existing Conditions Geologic Setting Foxlin Architects Resort View Project The project site is located in the San Diego County coastal plain within the Peninsular Ranges geomorphic province in California (California Geological Survey 2002). The north-south-trending Peninsular Ranges extend 900 miles from the Los Angeles Basin to the tip of Baja California in Mexico. The province varies in width from 30 to 100 miles wide and is bounded on the east by the Colorado Desert and Gulf of California, and on the west by the Pacific Ocean. The Peninsular Ranges are composed of a deep batholith (i.e., group of granitic plutons) that was emplaced 140 to 80 million years ago along the continental margin of North America (Norris and Webb 1990). Over time, regional uplift unroofed the basement rock and erosion exposed the buried plutons. The coastal plain is underlain by a thick sequence of Cenozoic marine and nonmarine units overlying Mesozoic plutonic basement rock (Demere and Walsh 2003). Quaternary faulting and ongoing uplift have resulted in the accumulation of alluvial fan deposits in many of the basins between the uplifted hills (Stephenson et al. 2009). The project site includes one geologic unit mapped at the surface (Attachment A, Figure 3): Pleistocene old alluvial flood plain deposits composed of poorly sorted, moderately well consolidated clay, silt, and sand (Kennedy and Tan 2007; Mccomas 2018). Pleistocene alluvium has yielded significant paleontological resources within approximately 10 miles of the project in coastal San Diego County (University of California Museum of Paleontology [UCMP] 2018). The SDNHM has collection records for at least eight fossil localities from Pleistocene alluvium that produced fossils of large-bodied Pleistocene mammals (e.g., ground sloth, wolf, bear, tapir, horse, camel, deer, giant bison, mastodon, and mammoth), small bodied mammals (e.g., mole, shrew, mice, and squirrel), and reptiles and birds (e.g., pond turtle, lizard, passenger pigeon, and hawk) (Demere and Walsh 1993; Mccomas 2018). The middle Eocene Santiago Formation unconformably underlies the Pleistocene alluvium at shallow depth in the project site and is intermittently exposed in San Diego County and the Peninsular Ranges. The unit was first named by Woodring and Popenoe (1945) for its type section near Irvine Lake in the Santa Ana Mountains (Morton and Miller 2006). The Santiago Formation was deposited in a marine to nonmarine environment during the middle Eocene and is conformable and locally gradational with the underlying Sespe Formation. The Santiago Formation is up to 2,700 feet thick near the type section in the Santa Ana Mountains and is composed of brownish-gray, coarse- to medium-grained sandstone, and light-gray to yellowish-gray silty sandstone with greenish-gray siltstone and conglomerate interbeds. The sandstone is poorly to well bedded, locally cross-bedded, and moderately-to well-indurated. The conglomerate contains well-rounded cobbles and pebbles of red and green metavolcanic rocks, plutonic rocks, quartzite, and siliceous volcanic rocks (Morton et al. 1976). Numerous specimens of vertebrate, invertebrate, and plant fossils have been documented from within the Santiago Formation in northern San Diego County, including taxa of terrestrial mammal, amphibian, shark, bird, mollusk, foraminifera, and petrified wood (Mihlbachler and Demere 2009; Mccomas 2018; Walsh 1996; UCMP 2018). Pagel C C r Paleontological Resource Potential of the Project Foxlin Architects Resort View Projed A search of the paleontological locality records on the SDNHM resulted in no previously recorded vertebrate fossil localities within Pleistocene old alluvial flood plain deposits within the project site or one-mile radius. Although relatively rare in the San Diego coastal plain, fossils have been collected at several localities within approximately 10 miles of the project site in coastal San Diego County (Mccomas 2018). Therefore, the Pleistocene old alluvial flood plain deposits have been determined to have a moderate paleontological sensitivity, in accordance with the SDNHM sensitivity classification scheme for paleontological resources (Demere and Walsh 1993; Stephenson et al. 2009). The middle Eocene Santiago Formation is not mapped at the ground surface within the project site, but the unit underlies the Pleistocene old alluvial flood plain deposits at an unknown depth. The Santiago Formation has yielded multiple Eocene vertebrate fossils, including specimens of reptiles, bony fish, shark and has been assigned a high paleontological sensitivity, in accordance with the SDNHM sensitivity (resource potential) classification scheme for paleontological resources (Demere and Walsh 1993; Mccomas 2018; Stephenson et al. 2009). Paleontological Field Survey In accordance with the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017), due to the preliminary finding of moderate paleontological sensitivity at the surface, a field survey of the project site was conducted by Rincon Staff Paleontologist Jorge Mendieta on November 27, 2018. During fieldwork, a pedestrian walkover was performed of the project site, published geologic maps were verified, and the ground surface within the project site was visually examined for the evidence of paleontological resources. Special attention was paid to areas where the underlying geologic deposits were exposed at the ground surface (e.g., small area on slope of central ridge). In addition, the geology and topography surrounding the project site was noted and nearby rock outcrops were examined for surface fossils. Project areas obscured at the surface by heavy vegetation or otherwise inaccessible due to safety concerns were not comprehensively examined. In the field, Mendieta utilized Global Positioning System (GPS), topographic maps, and aerial photographs to locate geologic formation boundaries and the extent of proposed ground disturbance. When a rock outcrop was encountered, the surface of the exposure was visually scanned for paleontological resources. Notes were taken on the visible geology and lithology and photographs were taken to document the survey (Photograph 1). The topography of the project site consists of a low central ridge flanked by a relatively flat ground surface (Photograph 2). The Pleistocene sediments mapped at ground surface are overlain by poorly developed soil composed of organic-poor tan to light brown loamy soil. Based on field observations made along the slopes of the low central ridge, the Pleistocene old alluvial flood plain deposits in the project site are composed of unconsolidated to poorly consolidated, tan to brown, coarse sand and silt, with scant angular granitic clasts of predominately fine pebble size, underlying several feet of soil development. Nearly 99 percent of the Pleistocene deposits underlying the project site are completely obscured by vegetation, soil development, and previous refuse dumping (Photograph 3). Vegetation consists of low trees, cut grasses, and sparse shrubs approximately 1-5 feet in height. Page8 r Foxlin Architects Resort View Project No fossil resources were discovered during fieldwork. However, the majority of the survey area was obscured by vegetation and soil development, which limited surface visibility. The Pleistocene sedimentary deposits that immediately underlie the project site, and the middle Eocene Santiago Formation that shallowly underlie the alluvium, have proven to be conducive to the preservation of vertebrate remains in San Diego County. Although fossils were not encountered at the surface of the project site, observed lithologic characteristics as well published mapping, literature, and museum records results, indicate that these geologic units may contain an unknown number of fossil resources at the subsurface, although their significance, abundance, and predictability of occurrence may vary.

View to the southeast Page 10 l r Foxlin Architects Resort View Project Impact Analysis and Recommendations The Pleistocene old alluvial flood plain deposits were determined to have a moderate paleontological sensitivity and no paleontological resources were discovered on the ground surface during the paleontological survey. In addition, the records by the SON HM did not identify previously recorded vertebrate fossil localities within Pleistocene old alluvial flood plain deposits in the project site or one-mile radius. However, according to the SON HM, several vertebrate localities have been documented nearby from the Eocene Santiago Formation, which shallowly underlies the Pleistocene alluvium in the project site. The Santiago Formation has been assigned a high paleontological sensitivity with a high potential for impacts to buried fossils during ground disturbance. Therefore, pursuant to the Carlsbad Tribal, Cultural, and Paleontological Resources Guidelines (2017), and in accordance with the SDNHM recommendations, a Principal Paleontologist shall be retained to prepare a Paleontological Mitigation and Monitoring Plan (PMMP). Implementation of the PMMP during ground-disturbing activities would successfully reduce potential adverse impacts to paleontological resources to a less than significant level.
