Subject: Biological Resources Due Diligence Assessment of the Camino Largo Property Dear Mr. Fontana:

At the request of California West Communities (Client), HELIX Environmental Planning, Inc. (HELIX) completed a biological due diligence assessment of the 9.3-acre Camino Largo Property(property or project site).The project site is comprised of Accessor Parcel Number(APN) 159-240-07 and is located at the northeast corner of North Santa Fe and Camino Largo, in the City of Vista (City), San Diego County.

The purpose of the assessment was to identify potential biological constraints to the development of the project site.This report provides a brief summary of the assessment results with a focus on the key biological constraints. Additional details can be provided if needed.This assessment only addresses biological constraints within APN 159-240-07 and does not include an assessment of any other off-site improvements should they be required by the project.

METHODS
HELIX's biological resources due diligence assessment included the review of readily available information and a general biological survey of the project site. HELIX reviewed current and historical aerial imagery,topographic mapping, soils mapping, Multiple Species Conservation Program (MSCP) data, and other pertinent biological resources data. In addition,the following documents provided by the Client were also reviewed:
• Initial Study and Mitigated Negative Declaration PC6-056, City of Vista, County of San Diego, dated September 2015; and
• Conditions of Approval PC6-056 Camino Largo 8, no date.

No other documents were provided in the project files or located independently.

HELIX biologist Matthew Dimson completed the general biological survey on June 8, 2021.The survey was conducted on foot with the assistance of binoculars and a Global Positioning System unit.The survey included a habitat assessment for special status species, potential jurisdictional aquatic resources, and identification of other notable biological resources.

RESULTS
Property Location
The 9.3-acre property is generally located east of Interstate(I)-5, west of 1-15, and south of California State Route 78, in the City of Vista, San Diego County, California. Specifically,the property is situated on the northeast corner of North Santa Fe Avenue and Camino Largo between Taylor Street to the south and Osborn Street to the north.The proposed project described in the project Initial Study Mitigated Negative Declaration (ISMND) dated September 18, 2015, includes the development of eight lots of varying sizes from 1.04 acres to 1.33 acres into residential developments (City 2015).The property is not located within the coastal zone.The project is not with a Multiple Species Conservation Area. The property is also located outside of any USFWS-designated critical habitat.

Existing Conditions Summary
The project site is characterized by a modest east-west trending ridge situated in the north central portion of the project site. Elevations on the project site range from 362 feet above mean sea level (amsl) at the top of the ridge to 296 amsl in the southwestern corner of the property adjacent to Camino Largo. Soil types on the project site include Placentia sandy loam, 2 to 9 percent slopes; Fallbrook sandy loam, 9 to 15 percent slopes; Bonsall sandy loam, 2 to 9 percent slopes, eroded; and Salinas clay loam, 2 to 9 percent slopes.The property is bordered to the north by agricultural fields and ranches, a single- family residence and undeveloped land to the south, single-family residences to the east, and Guajome Regional Park to the west.

Vegetation on the project site is limited to ornamental vegetation, including Eucalyptus (Eucalyptus sp.), Mexican fan palm (Washingtonia robusta), Canary Island date palm (Phoenix canariensis), and Peruvian pepper tree (Schinus molle) as well as non-native species and non-native grass, which is mowed on an annual basis. Historically,the site was used for agricultural production of row crops. More recently, the project site was used as a palm tree nursery.The frames of the hoop framed greenhouses are still present on the project site.

Jurisdictional Aquatic Resources
According to the 2015 project ISMND,the project site does not support any riparian habitat or other natural communities nor wetlands identified by federal, state, regional, or local agencies, policies, or regulations (City 2015).The project ISMND notes the property's proximity to the Guajome Lake tributary and San Luis Rey River, which include sensitive riparian habitats, southern cottonwood/willow riparian forest and coastal valley freshwater marsh emergent wetland. Therefore,the project includes a mitigation measure to reduce indirect impacts to the sensitive habitat and potential indirect impacts to special status wildlife within the adjacent parcel to the south,which is described in further detail below.

California Environmental Quality Act
As discussed above,the project applicant prepared an ISMND for the Camino Largo project (City 2015).

No biological document was referenced in the project ISMND (City 2015).

Based the project ISMND, candidate, sensitive, or special status plant or wildlife species are not expected to occur on the site due to the lack of suitable soils, habitat and the highly disturbed nature of the project site. HELIX verified these findings during the 2021 site visit.The project does not support any sensitive vegetation communities and therefore would not impact sensitive vegetation communities (City 2015).The 2021 site visit did note non-native grassland; however,the vegetation was disclosed in the 2015 ISMND and the lead agency did not require mitigation for impacts associated with this vegetation community. Generally, impacts to non-native grassland require 0.5:1 acre of mitigation.

Based on the project ISMND and the 2021 site visit, the project site does not contain any waters of the U.S. or state.Therefore, the project would not impact wetlands or other potentially jurisdictional waters,thus the project would not require wetland permits from the U.S. Army Corps of Engineers under Section 404 of the Clean Water Act (CWA) or the Regional Water Quality Control Board under Section 401 of the CWA, or a Streambed Alteration Agreement from the California Department of Fish and Wildlife.

Based on the project ISMND and the 2021 site visit, no sensitive plant or any animal species were observed, therefore no impacts to sensitive plant or animal species would occur. As a result, there are no habitat-related or species-specific mitigation requirements.

Potentially impacts to nesting birds was the only significant impact to biological resources identified in the ISMND and the only mitigation measures related to biological resources in the project documents.

The mitigation measure is provided below, as taken from the project's Mitigation Monitoring and Reporting Program (City 2015).

POTENTIAL BIOLOGICAL RESOURCES CONSTRAINTS
HELIX reviewed the project ISMND dated September 2015 and Conditions of Approval (COA) the following conditions relate to biological issues were noted:

Mitigation Measures
• BR-1 If avoidance of construction activities during the avian breeding season (typically March 1 through August 31, but as early as January 1 for some raptors as determined by a Qualified Biological Monitor) is not feasible,the Applicant and/or Owner shall hire a Qualified Biological Monitor with experience in conducting breeding bird surveys to conduct weekly on-site bird surveys beginning 30 days prior to initiation of any construction activities 9including, but not limited to, staging,grubbing and clearing).The weekly bird surveys shall be conducted to detect the nests of protected native birds and raptors occurring in suitable nesting habitat that could be disturbed during construction activities, and (as access to adjacent areas allows) any other such habitat within 300 feet of the disturbance area (and/or within 500 feet for raptors).The surveys shall continue on a weekly basis with the last survey being conducted no more than three days prior to the initiation of construction activities.The Qualified Biological Monitor shall HELIX
Environmental Planning

Biological Resources Due Diligence Assessment Page 4 of 6 Camino Largo Property
June 21, 2021
provide the City Planner with a summary report of the results of the recommended protective measures described above to document compliance with applicable State and federal laws pertaining to the protection of native birds.

If an active nest is located, construction activities within 300 feet of the bird nest(or within 500 feet for raptor nests) or otherwise as determined by the Qualified Biological Monitor, must be postponed until the nest is vacated and juveniles have fledged. and there is no evidence of a second attempt at nesting. Flagging, stakes. and/or construction fencing shall be used to demarcate the inside boundary of the buffer of 300 feet (or 500 feet) between the construction activities and the nest. All contractors working on-site shall be instructed by the Qualified Biologist on the sensitivity of the area.The Qualified Biological Monitor shall immediately notify the City Planner if project activities damage active avian nests.

If the Qualified Biological Monitor determines that a narrower buffer between the project activities and observed active nests is warranted. he/she shall submit a written explanation to support this determination (e.g., species-specific information: ambient conditions and birds' habituation to them: etc.)to the City Planner, and upon request to the California Department of Fish &Wildlife. Based on the submitted information,the City Planner, in consultation with the Qualified Biological Monitor. will determine whether to allow the narrower buffer.

Though not a mitigation measure,the project ISMND includes the following measure regarding potential indirect impacts:

Construction of the proposed project could result in significant indirect temporary impacts to special- status wildlife from adverse "edge effects" on the sensitive habitat within the adjacent parcel to the south. Edge effects typically include dust, construction-related soil erosion and runoff, lighting, and construction-related noise. Dust control, erosion control, and water quality protection measures are addressed in the Air Quality and Hydrology and Water Quality sections of this document, and would be part of the Conditions of Project Approval. Potential impacts from lighting would not be significant, as addressed in the Aesthetics section of this IS/MND, as there are two street lights planned along the road that is required to meet the Zoning Ordinance. However, construction-related noise would be significant within approximately 500 feet of a raptor nest or within 300 feet of a nesting bird. However, with the implementation of Mitigation Measure BR-1 noted above,this impact would be reduced to less than significant levels.

Conditions of Approval (no date)
• F.1.f.The applicant shall obtain any necessary permits and clearances from all public agencies having jurisdiction over the project due to its type, size, or location, including but not limited to the U. S.Army Corps of Engineers, California Department of Fish &Game, U. S. Fish and Wildlife Service and/or San Diego Regional Water Quality Control Board (including NPDES), San Diego County Health Department, prior to the issuance of grading permits. • BR-1 If avoidance of construction activities during the avian breeding season (typically March 1 through August 31, but as early as January 1 for some raptors as determined by a Qualified Biological Monitor) is not feasible,the Applicant and/or Owner shall hire a Qualified Biological Monitor with experience in conducting breeding bird surveys to conduct weekly on Environmental Planning

surveys beginning 30 days prior to initiation of any construction activities 9including, but not limited to, staging,grubbing and clearing).The weekly bird surveys shall be conducted to detect the nests of protected native birds and raptors occurring in suitable nesting habitat that could be disturbed during construction activities, and (as access to adjacent areas allows) any other such habitat within 300 feet of the disturbance area (and/or within 500 feet for raptors).The surveys shall continue on a weekly basis with the last survey being conducted no more than three days prior to the initiation of construction activities.The Qualified Biological Monitor shall provide the City Planner with a summary report of the results of the recommended protective measures described above to document compliance with applicable State and federal laws pertaining to the protection of native birds.

If an active nest is located, construction activities within 300 feet of the bird nest(or within 500 feet for raptor nests) or otherwise as determined by the Qualified Biological Monitor, must be postponed until the nest is vacated and juveniles have fledged. and there is no evidence of a second attempt at nesting. Flagging, stakes. and/or construction fencing shall be used to demarcate the inside boundary of the buffer of 300 feet (or 500 feet) between the construction activities and the nest. All contractors working on-site shall be instructed by the Qualified Biologist on the sensitivity of the area.The Qualified Biological Monitor shall immediately notify the City Planner if project activities damage active avian nests.

If the Qualified Biological Monitor determines that a narrower buffer between the project activities and observed active nests is warranted. he/she shall submit a written explanation to support this determination (e.g., species-specific information: ambient conditions and birds' habituation to them: etc.)to the City Planner, and upon request to the California Department of Fish &Wildlife. Based on the submitted information,the City Planner, in consultation with the Qualified Biological Monitor. will determine whether to allow the narrower buffer.

CONCLUSION
In conclusion,the project site has the potential for nesting bird habitat, including raptor species.

Therefore, any grading, brushing, or clearing conducted during the migratory bird season, March 1- August 31 (but as early as January 1 for raptor species), has the potential to impact birds. If grading, brushing, or clearing activities occur during the general bird breeding season, a qualified biologist must conduct nest surveys 30 days prior to the construction activities and conduct weekly surveys, with the last one occurring no later than three days prior to the initiation of construction activities.

Addendum to Cultural Resources Survey and Assessment for the Camino Largo Subdivision Project I December 2021 1 .0 INTRODUCTION/BACKGROUND
The Camino Largo Residential Project (project) is located in the City of Vista (City) in northwestern San Diego County.The project site is northeast of the intersection of North Santa Fe Avenue and Camino Largo, north of Taylor Street, and south of Osborne Street, a short distance south of State Route 76.

HELIX Environmental Planning, Inc. (HELIX) conducted a cultural resources study in 2015 as part of the proposed Camino Largo Subdivision Project (Robbins-Wade and Giletti 2015).That study, which is addressed in more detail below,was performed under an as-needed contract for cultural resources consulting services with the City's Community Development Department.The cultural resources study conducted by HELIX in January 2015 consisted of an archaeological survey and testing program, outreach to the Native American community, and review of historic maps and aerial photographs. As a result of that study, previously undocumented prehistoric resources were identified in the area of a previously recorded historic era resource (CA-SDI-14730);the resources were assessed as not significant under the California Environmental Quality Act (CEQA).

The current study by HELIX was conducted in 2021, as an update to the earlier study, and includes:
obtaining an updated records search from the South Coastal Information Center(SCIC), a new search of the Sacred Lands File from the Native American Heritage Commission (NAHC), outreach to the Native American community, and survey of the project.The previously recorded cultural resource was noted during the October 2021 survey as essentially the same as it had been described.

2.0 2015 STUDY
HELIX conducted a cultural resources study for the proposed project in 2015.A records search was conducted at SCIC for the project area and a one-mile radius around it. Historic maps and aerial photographs were also reviewed, and HELIX contacted the Native American Heritage Commission (NAHC) for a search of its Sacred Lands File.The field survey for cultural resources was conducted in January 2015 by a HELIX archaeologist, a historian/historic archaeologist, and a Luiseno Native American monitor from Saving Sacred Sites.The project site was walked in parallel transects spaced 10 meters apart. Historic archaeological site CA-SDI-14730(P-37-016187) was reidentified, and three previously undocumented prehistoric artifacts were noted during the survey and included under the same site number already assigned to the location.The project area has been subject to a great deal of past disturbance, due to decades of rural residential and agricultural use. Soils have been moved around within the project area, and the ground surface in portions of the property was obscured, due to ongoing nursery uses.

One archaeological site was previously recorded within the Camino Largo project area: CA-SDI-14730.

CA-SDI-14730 was originally recorded in 1998 as a historic site of unknown age.The site record described the site as:

Concrete covered cobble house foundation, remnants of wood 1"tongue and groove floor held up by wood pilings; demolition debris consisting of plywood, metal sheeting, and metal pipes. Cobble and concrete retaining wall is located on the slope to the north of the house foundation. Adjacent reservoir(30' east of foundation) is also comprised of concrete covered cobble walls. It is unknown if a shed (approximately 125' southeast) is related to the foundation and reservoir.The dilapidated one room shed is constructed of plywood and sheet metal and set on small concrete blocks.The 1'wood floor boards HELIX
Environmental Arannrog
1 Addendum to Cultural Resources Survey and Assessment for the Camino Largo Subdivision Project I December 2021 set on floor joists. Electricity was wired to the shed and a toilet and sink are inside.The last use of the building was apparently as a storage facility as hardened bags of cement and rolls of tar paper are still inside.A small concrete lined basin, perhaps a pond or trough is located 50' south of the foundation and reservoir [site record, on file at SCIC].

Subsequent to the fieldwork conducted by HELIX in January 2015, it was found that site P-37-029400 is the same resource as CA-SDI-14730 and that a historic study and evaluation had been completed for that resource, although the location for P-37-029400 on file at the SCIC is outside the Camino Largo project area, due to a mapping error.The 2015 HELIX report is on file at the SCIC, as is the report evaluating the historic resource recorded as P-37-029400.

A testing program was conducted on January 27, 2015,to determine the extent and nature of subsurface cultural deposits, if any.Testing included the collection of the three surface artifacts (two manos and one piece of debitage) and the excavation of four shovel test pits (STPs). Three STPs were placed in proximity to the surface artifacts noted; the fourth was located to provide continuity among all test units. Soils excavated were passed through 1/8-inch mesh rocker screens. Each STP was excavated to a minimum depth of 60 centimeters (cm).STP 1 was excavated to 70 cm in order to achieve two sterile levels; a flake was recovered in the 40-to 50-cm level.Two additional flakes were found, one each in STP 2 and STP 3. In all,two manos and four pieces of debitage were collected at the site. Due to the paucity of artifacts and general lack of subsurface cultural material, no test units were excavated.

The 2015 report concluded:

The prehistoric component of CA-SDI-14730 contains little cultural material and has very limited research potential.As such,the site does not meet the criteria for nomination to the California Register and is not a significant resource. It must be noted that all areas of past cultural activity hold some significance to the Luiseno people [Robbins-Wade and Giletti 2015:20].

During the 2015 study,the historic period features were found essentially as previously recorded, with the addition of an area of butchered bone and the fact that the shed noted on the original site record is no longer standing; it is now a pile of wood and metal. Historic archaeologist Stephen Van Wormer noted the layout of the "reservoir" suggests it might instead have been a pool. One end of the structure is shallower than the other, with a steeply sloping bottom,which would not have been practical for a reservoir but would have been normal for a swimming pool.The 1998 historic report calls this feature a pool but notes that a swimming pool "in the days before modern health requirements often performed double-duty as a reservoir" (Gregory 1998:6).

The house and pool/reservoir are visible on historic aerial photographs as far back as 1938 (historicaerials.com). No structures are shown in the project area on tax factor aerial photographs from 1928, although there are structures close by on the east side of what is now North Santa Fe Avenue, in addition to the features of the Guajome Ranch House.A house appears on the property on the 1948 USGS map(7.5' San Marcos quadrangle), but no structures are visible here on the 1901 USGS topographic map (15' Escondido quadrangle), which was surveyed in 1891 and 1898.This information indicates a construction date of the house, and at least some of the associated features, as sometime during the 1930s. Given this date of construction,the house and associated features do not represent the pioneer farming phase of development in the area and are essentially modern.The report concluded that CA-SDI-14730 does not meet the criteria for a historical resource/significant resource under CEQA; HELIX
Environmental Arannrog
2 Addendum to Cultural Resources Survey and Assessment for the Camino Largo Subdivision Project I December 2021 thus, impacts to it would not constitute significant effects.The historic-age residential property was assessed as not a significant resource.

No Traditional Cultural Resources(TCRs)were identified within or in the immediate vicinity of the project area during the 2015 study. Letters were sent to the contacts listed by the NAHC in January 2015. Written responses were received from the Pala Band of Mission Indians, the Pauma Band of Luiseno Indians, and the Rincon Band of Luiseno Indians (Rincon).The Pala Tribal Historic Preservation Office indicated that the project is within the boundaries of the territory that the tribe considers its Traditional Use Area.They recommended archaeological monitoring and requested to be given updated information as the project progresses.The Pauma Band responded that, although they are unaware of any specific cultural resources in the project vicinity,the Guajome area is culturally sensitive.They,too, recommended archaeological monitoring during any ground-disturbing activity.The Rincon Band indicated that the project area is within "Rincon's specific area of Historic Interest" and noted the possibility of encountering human remains and associated artifacts; "all culturally associated findings are culturally significant to the Rincon people" (letter from Rose Duro, Rincon Culture Committee Chair, February 10, 2015). Rincon also requested that the Rincon Cultural Resources Department be afforded the opportunity to provide cultural monitors for any ground-disturbing activity.

The San Luis Rey Band of Mission Indians provided Native American monitors for all fieldwork through their monitoring entity,Saving Sacred Sites.

3.0 2021 STUDY UPDATE
In October 2021, HELIX obtained an updated records search at SCIC for the project site and a one-mile radius.The records search showed the only cultural resources recorded within the one-mile search radius since the records search for the 2015 report were those recorded and evaluated by HELIX for the project in 2015 (Robbins-Wade and Giletti 2015). While several reports have been filed for the search radius since the records search conducted for the previous study,the only one within or adjacent to the project site was the 2015 HELIX report.

A survey of the project was performed on October 11, 2021, by HELIX archaeologist Mary Villalobos, and Cami Mojado of Saving Sacred Sites, who served as the Native American monitor. CA-SDI-14730 was found to be in the same condition as it was during the 2015 study.Two newly identified isolated cultural items were identified and documented in the northern/central portion of the project; these included a quartz flake and a large Ostrea spp. shell, which were then recorded on a Department of Parks and Recreation (DPR) site form update. During a subsequent site visit on December 16, 2021, other shell was observed, but it was noted that the shell appears to be a fossil.

In-person meetings were held with HELIX and San Luis Rey and Rincon to discuss the Tribal sensitivity of the project and determine any measures to be taken to protect Tribal cultural resources within the project, as discussed below under Tribal Outreach.

4.0 TRIBAL OUTREACH
Tribal outreach efforts from the 2015 study resulted in responses from the Pala Band of Mission Indians, the Pauma Band of Luiseno Indians, and the Rincon Band of Luiseno Indians, as discussed above under HELIX
Environmental Arannrog
3 Addendum to Cultural Resources Survey and Assessment for the Camino Largo Subdivision Project I December 2021 Section 2.0,2015 Study.All the tribes who responded indicated the cultural sensitivity of the area and recommended that tribal cultural monitors be present for any ground-disturbing activity.

For the current study update, HELIX contacted the NAHC for a Sacred Lands File search and a list of Native American contacts in October 2021.The Sacred Lands File search did not indicate the presence of Native American cultural resources in the immediate project area (see Confidential Appendix A, Native American Correspondence). Letters were sent to the contacts listed by the NAHC in November 2021 (see Confidential Appendix A). In addition, detailed project data was provided to both the San Luis Rey Band of Mission Indians and the Rincon Band of Luiseno Indians, based upon the results from both the previous and current studies. Responses were received from Rincon, San Luis Rey, the Pechanga Band of Indians, and the San Pasqual Band of Mission Indians (San Pasqual), as summarized below.

NATIVE AMERICAN CONTACT PROGRAM RESPONSES
Contact/Tribe Response
San Luis Rey Band of Mission Responded on November 30,2021, requesting to meet in person to Indians discuss the project and Tribal sensitivity thereof. Meeting was held on December 2. Based on the cultural sensitivity of the area and the results of monitoring of other projects in the area, monitoring is recommended.

Rincon Band of Luiseno Indians Responded on November 18,2021 that the project is located within their specific area of historic interest. Requested a field visit,which was held on December 16,2021.An email summarizing Rincon's concerns was received on December 23, 2021.The project has the potential to impact TCRs,and CA-SDI-14730 should be assessed in the context of other recorded sites as possibly part of a larger resource.The proposed project is located within a known traditional Luiseno place and is connected with Luiseno beliefs and practices continued to this day.

Pechanga Band of Indians Responded on December 16, 2021,stating that the project is situated within the Band's ancestral territory and requesting consultation with the City, archaeological and Native American monitoring,and copies of any project documentation.

San Pasqual Band of Mission Responded on November 24,2021,stating that while the project is Indians located outside reservation boundaries, it is located within San Pasqual's Traditional Use Area.

On November 18, 2021, Rincon responded that, "The identified location is within the Territory of the Luiseno people and is also within Rincon's specific Area of Historic Interest (AHI)" (letter from Cheryl Madrigal,Tribal Historic Preservation Officer/Cultural Resources Manager, November 18, 2021). Further, the following was included in Rincon's response:

After review of the provided documents and our internal information,the Band has specific concerns that the project may impact tangible Tribal Cultural Resources (TCRs), Traditional Cultural Landscapes (TCLs), and potential Traditional Cultural Properties (TCPs). Embedded in these resources and within the AHI are Rincon's history, culture, and continuing traditional identity.

Based on the information provided above,the Rincon Band recommends conducting an archaeological/cultural resources study,to include an archeological record search and complete intensive survey of the property.Additionally, we ask that a professional Tribal HELIX
Environmental Aramnrog
4 Addendum to Cultural Resources Survey and Assessment for the Camino Largo Subdivision Project I December 2021 monitor from the Rincon Band to accompany the archaeologist during the survey. If the field investigation already concluded, we ask to be provided the opportunity to visit the project site to assess impacts to TCRs,TCLs, or TCPs.The Rincon Band further requests to consult directly with the lead agency regarding project impacts to cultural resources.

A copy of Rincon's written response was forwarded to the City of Vista for Assembly Bill (AB) 52 consultation purposes.

San Luis Rey responded in writing on November 30, 2021, requesting to meet in person to discuss the project and Tribal sensitivity thereof(letter from Cami Mojado, Cultural Resources Manager, November 30, 2021). San Luis Rey stated:

Our Tribe has intimate knowledge about the many discoveries made throughout the Project Area and is aware of cultural resource sites within close proximity to the proposed Project. We strongly urge caution in assessing the land encompassing the Project for any ground disturbing purposes, as well as incorporating the presence of a Luiseno Native American monitor during all ground disturbing activities (including but not limited to any and all boring activities) and cultural resource assessment surveys San Luis Rey requested copies of any survey report prepared for the project and that a Luiseno monitor be present during the survey of the project.A copy of their written response was forwarded to the City.

The Pechanga Band of Indians responded in writing on December 16, 2021, stating that the project is located within the Tribe's ancestral territory and requesting government-to-government consultation with the City, monitoring by a qualified archaeologist and Tribal monitor from Pechanga, and copies of project documentation including grading plans, project reports, and site records pertaining to the project area (letter from Paul Macarro, Cultural Coordinator, December 16, 2021). A copy of their written response was forwarded to the City.

San Pasqual responded in writing on November 24, 2021, stating that while the project is located outside reservation boundaries, it is located within San Pasqual's Traditional Use Area (letter from Angelina Gutierrez on behalf of Desiree M. Whitman,Tribal Historic Preservation Officer, November 24, 2021). Further, San Pasqual's response included the following language:
...we would like to engage in consultation so that San Pasqual can have a voice in developing the measures that will be taken to protect these sites and mitigate any adverse impacts. We would appreciate being given access to any cultural resource reports that have been or will be generated during the environmental review process so we can contribute most effectively to the consultation process.

A copy of San Pasqual's written response was also forwarded to the City for consultation purposes.

4.1 IN-PERSON MEETINGS
HELIX Principal Investigator Mary Robbins-Wade met with Ms. Mojado on December 2, 2021, to discuss the project and potential cultural resources concerns.They discussed the numerous archaeological sites in the vicinity that are all part of the overall Wahaumai(Guajome)village complex. Ms. Mojado noted that monitoring at nearby projects, such as North Coast Church and Vista Sports Park,were positive for cultural resources.Thus, it is anticipated that cultural resources would be encountered during ground- HELIX

5 Addendum to Cultural Resources Survey and Assessment for the Camino Largo Subdivision Project I December 2021 disturbing activities for the Camino Largo project, and monitoring by an archaeologist and a tribal cultural monitor is recommended.

Ms. Robbins-Wade met with Rincon Tribal Historic Preservation Officer Cheryl Madrigal at the project site on December 16, 2021,to walk the site and discuss the cultural sensitivity of the area.They discussed the location of the project site within the larger landscape of the prehistoric/ethnohistoric village of Wahaumai and the potential for buried cultural resources that could not be seen during the surveys. Following the field visit, Rincon provided a letter via email summarizing the Tribe's concerns.

The Tribe is concerned that the project has potential to impact Tribal Cultural Resources and potential historic properties with traditional property significance.The proposed project is located within a known traditional Luiseno place and is connected with Luiseno beliefs and practices continued to this day. In particular, the Tribe is concerned with the pre-contact component of CA-SDI-14730,which consist of three pre-contact artifacts that were noted in the 2015 survey.The Tribe asks that these cultural materials will be reviewed and assessed in context to the previously recorded archaeological sites and isolates as we believe there is potential that this site is part of a larger historic property.

Rincon also provided mitigation language that will be forwarded to City staff.The mitigation language provided covers standard mitigation monitoring procedures and protocols.

5.0 CONCLUSION
An updated cultural resources study performed for the project has determined that recommendations provided by HELIX in 2015 resulting from a survey of the project and testing of site CA-SDI-14730 remain valid in terms of archaeology; however,the previous study did not fully consider tribal cultural resources. While the current survey and the previous study found that the site was ineligible for listing in the CRHR and does not qualify as a significant resource, due to its limited research potential,the association of the site with the overall cultural landscape must be revisited to address the potential significance as a TCR.This will be addressed during the AB 52 consultation between the City and consulting Tribes.As such,the monitoring recommendations made for the project in HELIX's 2015 report remain valid. An archaeologist and a Native American monitor should be on-site for all ground- disturbing activity, including brushing/grubbing,grading,trenching, etc., in areas where there is a reasonable expectation of encountering cultural material (e.g., not in formational deposits). If cultural material is encountered,the archaeological and Native American monitors will have the authority to temporarily halt or redirect grading and other ground-disturbing activity while the features and/or artifacts are assessed, and appropriate mitigation measures are designed and implemented if necessary.

In the event of a discovery, significance assessments and mitigation measures will be developed in consultation among the archaeological consultant,the Native American monitors, and City staff.

Monitoring requirements and mitigation measures to be implemented in the event of an inadvertent discovery of cultural resources during the monitoring are detailed in the Initial Study/Mitigated Negative Declaration for the project.

PROJECT AND SITE DESCRIPTION
The site is currently occupied by a palm tree nursery in the western half of the site. The central and eastern portion of the site is currently undeveloped covered by grass and some trees. An abandoned concrete lined reservoir is present in the central portion of the site that was fed by wells south of the property and used for water storage by previous owners. Several ancillary structures exist in the western portion of the site to support the nursery. Abandoned vehicles and abandoned structure foundations are present at various locations across the site. The site is moderately sloping away from a north central high point. Elevations on the site range from a high of 361 feet Mean Sea Level (MSL) on north central lots to 308 feet MSL at the southeastern limits and 295 feet MSL at the southwestern limits. The Existing Site Map shows the current property configuration.

Based on review of the referenced plans, the proposed development will include constructing 48 single-family residential homes, private roadways, retaining walls, two biofiltration basins, tot lot, underground utilities, surface improvements, and landscaping. Finish building pad grades range from 349 feet MSL on Lot 28, 311 feet MSL on Lot 45 on the southeast and 303 feet MSL On Lot 9 on the southwest. Slope, lot and street storm drain runoff will be captured by inlets that empty into the proposed biofiltration basins at the southeast and southwest site limits and outlet to a proposed storm drain system along Camino Largo.New sewer and water utilities will service each lot and will connect to utilities on Camino Largo.

According to the referenced lot study,the proposed grading will consist of approximately 62,630 cubic yards of excavation and 32,370 yards of fill creating an export of approximately 30,260 yards. The referenced geotechnical report provided recommendations for shrink of 10 to 20 percent for surficial soils and 10 to 20 percent bulk for granitic rock materials.

Cut and fill slopes with maximum heights of 23 and 18 feet,respectively, are planned with inclinations of 2:1 (horizontal to vertical), or flatter. Retaining walls are planned for each lot with maximum heights of approximately 5 feet. Proposed cuts within the lots will be a maximum of 20 feet located mainly in the central lots and proposed fills are a maximum of 22 feet within Lot 3. An additional 3 to 4 feet of overexcavation below proposed finish pad grades and at least one foot below the deepest Geocon Project No.G2721-11-02 -3- May 17,2021

utility within roadways within granitic rock areas should be anticipated. Although no proposed utility plan was provided, we anticipate the proposed excavations for utilities may be a maximum of 8 feet in depth. The Lot Study shows the proposed configuration of the site.

SUMMARY
The purpose of this letter is to summarize the soil and geologic conditions and geologic hazards that potentially affect site development. The information and our opinions provided herein are based on review of the referenced geotechnical report and referenced plan.

Three geotechnical reports were prepared for the site that included a preliminary investigation in 1997, an update geotechnical report in 2008 and a subsequent update report in 2012. In addition, an Air- Track study was performed in 1998. The subsurface field investigations included excavating 8 trenches and 13 Air-Track borings. Laboratory testing included maximum dry density and optimum moisture content, direct shear, pH and resistivity, chloride testing, expansion index and water-soluble sulfate content. The reports summarize the local geology, geologic units, geologic structure, faulting potential, seismicity, seismic design criteria, excavation characteristics, liquefaction potential and groundwater. The recommendations in the report include remedial grading, fill placement, compaction, foundations,retaining walls,preliminary pavement, corrosivity and concrete flatwork.

The following is a summary of the main geotechnical engineering aspects associated with development of the Camino Largo residential project.

Geocon Project No.G2721-11-02 -4- May 17,2021

Geologic Units
The referenced geotechnical reports indicate the geologic conditions consist of surficial soils composed of undocumented fill and alluvium overlying formational granitic rock within the area of development.

The undocumented fill is located at various locations across the site with a maximum anticipated thickness of 5 feet to create level areas. The alluvium is located mainly in the low-lying areas, in the east and west portions of the site overlying formational granitic rock and consists of loose to medium dense, dry to damp, silty sand with a maximum thickness of about 5 feet. The granitic rock consists of highly to moderately weathered, fine- to coarse-grained tonalite that will mostly generate granular soils when excavated. The granitic rock has some unweathered corestones beneath the existing surface and may be encountered during construction. Lots that expose granitic rock at grade should be undercut and replaced with properly compacted fill soil. The previous air-track borings were located in the north central portion of the site that will have the largest cuts. The results indicate that the granitic rock is generally rippable and that blasting will not be necessary to achieve finish grade or undercut grades within proposed lots and streets. However, the air-track borings show that un-rippable hard corestones will be encountered that will need to be individually placed in deeper fills or broken down to smaller sizes to properly place within compacted fills.

The undocumented fill, alluvium upper portions of the granitic rock are considered unsuitable to support the proposed development and will require remedial grading. The surficial soil generated during remedial grading can be reused as new compacted fill if generally free of debris and vegetation.

The referenced reports recommend that the upper 4 to 5 feet below existing grades across the site will require remedial grading. Rock greater than one foot in diameter will need to be placed at least 5 feet from finish grades within pads and 10 feet from finish grade within the proposed roadways. Rocks larger than 4 feet in diameter will need to be broken to smaller sizes to allow for proper placement within compacted fills.

The granitic rock is considered suitable for support of the planned development and improvements.

Excavation of the undocumented fill, alluvium and upper portions of the highly weathered granitic rock should generally be possible with moderate effort using conventional, heavy-duty grading equipment. Excavation of granitic rock should generally be possible with heavy to very heavy effort using conventional, heavy-duty grading and trenching equipment. Air-track borings generally indicate rippable conditions for the granitic rock. The large corestone rocks that will likely be encountered at depth within the granitic rock will need to be broken down to manageable sizes and properly placed within the compacted fill. If hard granitic rock is encountered that is too difficult to excavate, localized rock breaking will be required that will generate oversize rock requiring special handling and placement. We expect some hard rock will be encountered on the site based on our review of the air- track borings. However, we do not expect that blasting will be required to excavte granitic rock. The grading and underground contractors will need to determine the magnitude of hard rock that will be encountered based on the type of equipment that will be used during grading and trenching operations.

Geocon Project No.G2721-11-02 -5- May 17,2021

Groundwater
Prior site investigations did not encounter localized seepage or groundwater during trenching. Seepage and groundwater conditions were not encountered within the granitic rock but may be perched on the contact between the surficial soils and granitic rock contact. It is common to encounter seepage within formational units during the rainy season or due to adjacent landscaping. Groundwater is not expected to be a limiting factor during grading and improvements at the site. Groundwater is not expected to affect the performance of the site once grading is complete. In addition, temporary seepage conditions could occur after heavy rain events that could locally affect construction activities. Once site development is complete and surface water flow is controlled, seepage conditions should not affect the performance of the development. However, it is common to install slope toe drains at the base of rock cut slopes to intercept irrigation water and reduce the potential for perched water within lots.

Liquefaction
The referenced report from 2008 evaluated the liquefaction potential to be negligible due to the lack of permanent near surface groundwater and dense nature of underlying granitic rock.

Faulting and Seismicity
The site is located in an area that is subject to possible moderate to strong ground shaking from regional seismic events on active faults. The nearest active faults are the Elsinore fault zone located approximately 17 miles to the northeast of the site and the Rose Canyon/Newport Inglewood fault zone located approximately 10 miles to the west. The potential for seismic shaking is similar to that of the surrounding area. Based on the referenced studies and our experience in the area, the site is not located on active, potentially active or inactive faults. Therefore, faulting or surface rupture will not have an impact to site development.

Slopes
Maximum fill slope heights will be approximately 18 feet and will be constructed at inclinations of 2:1 (horizontal to vertical) or flatter. The outer 15 feet of fill slopes will require the use of on-site granular soils for construction that will have adequate shear strength characteristics. Therefore, slope instability for new constructed slopes will likely not be a hazard for development if proper compaction is achieved within slope zones during grading and improvement operations. Cut slopes in rock of up to 23 feet in height at a 2:1 inclination will be constructed and are anticipated to be stable. Observations of the rock will be required during the grading operations to evaluate weak planes or fractures.

Settlement
Design fill depths will be a maximum of approximately 22 feet after performing remedial grading operations. We anticipate the undocumented fill and alluvium will be removed completely during Geocon Project No.G2721-11-02 -6- May 17,2021

remedial grading. The compression related settlement within the granitic rock after remedial grading is performed due to loading from fill placement will be negligible based on the reported conditions, laboratory testing, and our experience with that geologic unit. The grading specifications indicate that fill should be placed near to slightly above their optimum moisture content,which will reduce the magnitude of post-grading hydro-compression. Settlement of fills will be a design factor that should be considered when preparing specific building foundation recommendations, which typically include total and differential fill thicknesses and expansion potential of the near surface finish grade soils. Fill depths below proposed pad grades will vary from 3 to 22 feet. We estimated that maximum post-construction settlement would be 1%2 inches with a maximum differential settlement of 3/4-inch in 40 feet.

Expansive and Corrosive Soils
The on-site soils will have a very low to low expansion potential and negligible corrosive potential.

The soils generated from excavations within the alluvium and colluvium are expected to possess a "very low" to "low" expansion potential (expansion index of between 0 and 50). The soils generated from excavations within granitic rock and its overlying topsoil are expected to possess a "very low" expansion potential (expansion index of 20 or less). The on-site soils are expected to have an "SO" water-soluble sulfate exposure to concrete improvements according to the 2019 CBC and ACI 318-14 Chapter 19. The sulfate exposures are not anticipated to impose special concrete mix design requirements for concrete foundations, buried concrete structures, and exterior concrete flatwork once finish grade soils have been tested. The risk of expansive soil affecting the proposed development is considered low due to the anticipated "very low" to "very low" expansion potential of the soils generated from excavations of onsite soils. The risk of corrosive soils affecting the proposed development due to water-soluble sulfate is considered very low.

CONCLUSIONS
The scope of the referenced geotechnical reports included providing recommendations for the construction of the proposed residential development to reduce impacts of the existing soil and geologic conditions to tolerable levels. We opine the geotechnical reports are adequate for use in preparing a construction budget for the proposed project. However, the reports were prepared using the 2010 California Building Code (CBC) and should be updated for seismic design using the 2019 CBC. In addition,the storm water management report should be updated using the most recent version of the county storm water manual.

We opine the site can be developed for the proposed residential development provided the recommendations outlined in this due diligence letter and the referenced geotechnical investigations and pending update report are used in design and construction of the project. Geotechnical hazards are not present on the site that would prohibit development and Geocon Incorporated supports the proposed project. We should be contacted to provide an update geotechnical report when the property has been obtained.

Geocon Project No.G2721-11-02 -7- May 17,2021

The following is a list of geotechnical items that should be considered during due diligence:

1. Foundation recommendations were provided for the proposed single-family residences in the referenced geotechnical reports consisting of conventional foundations with slab-on-grade construction based on the anticipated expansion potential of the finish grade soils and the anticipated static post-construction total and differential fill settlements. These recommendations should be updated using the 2019 CBC. Post-tension foundation recommendations were not provided in the geotechnical reports and should be considered as a viable option for residential construction. We expect the majority of the proposed lots will be Category I and 11 foundations. Depending on remedial grading depths, some lots may require a Category III foundation.We do not expect the existing soil will possess a water-soluble sulfate content greater than "SO"; therefore, specialized concrete mix design will not be necessary from a geotechnical engineering standpoint.

2. The BMP basins will be excavated to a maximum depth of 2 to 3 feet(Elevation of 292.5 feet MSL in the western basin to 308 in the eastern basins)below existing grades. According to the 2012 report, a low permeable site was assumed. The referenced report recommended fully lined basins. Additional study will likely be required by the County of San Diego to determine final basin design.

3. Retaining wall plans were not provided for a review during this study. Updated recommendations using the 2019 CBC should be incorporated into the proposed retaining wall plans.

4. Existing subsurface boulders (corestones) located on the various locations on the site will require rock breaking to manageable sizes to allow for proper placement within deeper fill areas. In addition, boulders or corestones generated during granitic rock excavation will also require break down and placement within deep fills. Based on our review of the field investigation results, we anticipate that only minor areas of hard rock should be encountered.

5. We do not expect that remedial grading will affect properties along the perimeter of the site if performed properly.

6. Typical subgrade preparation time of exterior flatwork on lots is expected.

7. Typical subgrade preparation time of private street and concrete hardscape and sidewalk areas is expected.

8. Typical pavement thickness is expected for the planned private roadways as reported in the geotechnical reports.

9. Typical concrete costs for foundations and exterior flatwork are expected if the lots are capped with granular soils.

10. Typical design and use of landscape area drains and building roof drains are expected.

11. We expect typical long-term maintenance costs for surface improvements including sidewalks, curbs,and homeowner flatwork since we anticipate the lots will be capped with granular"very low"to"low"expansive soils.

12. Anticipate typical homeowner callback time and frequency for repairs to surface improvements.

PHASE I AND II ENVIRONMENTAL SITE ASSESSMENT REPORT

1. INTRODUCTION
Geocon, Inc. (Geocon) has performed a Phase I and II Environmental Site Assessment (ESA) of the Camino Largo property (the Site) in Vista, California. California West Communities (the Client) requested the Phase I ESA to provide information regarding the potential for existing hazardous substances and/or petroleum product impacts at the Site as part of their due diligence prior to purchasing the Site. This report describes the methodology and procedures and present the findings of the Phase I and II ESA.

1.1 Purpose and Objectives
The purpose of the Phase I ESA was to identify evidence or indications of`recognized environmental conditions' (REC) as defined by the American Society for Testing and Materials (ASTM)Designation E 1527-13 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process. Section 1.1.1 of ASTM Designation E 1527-13 defines an REC as "the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not recognized enviromnental conditions." De minimis conditions are those that generally do not present a threat to human health or the environment and that generally would not be the subject of enforcement action if brought to the attention of appropriate governmental agencies.

ASTM Designation E 1527-13 also defines `Historical' and `Controlled' RECs. They define an `Historical REC' (HREC) as "A past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls)." ASTM defines a `Controlled REC' (CREC) as "a recognized environmental condition resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority (for example, as evidenced by the issuance of a no further action letter or equivalent, or meeting risk-based criteria established by regulatory authority), with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls)." An HREC is not an REC if a property meets current standards for unrestricted use. A CREC remains an REC by definition when the property does not meet the unrestricted use requirements unconditionally.

Project No.G2721-62-01 -1- May 12,2021

We also conducted the Phase I ESA in general accordance with the requirements of 40 Code of Federal Regulations (CFR) Part 312 titled Standards and Practices for All Appropriate Inquiries, as required under Sections 101(35)(B)(ii) and (iii) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The purpose of conducting an all appropriate inquiries investigation into the previous ownership and uses of a property is to meet the provisions necessary for the landowner, contiguous property owner, and/or bona fide prospective purchaser to qualify for certain landowner liability protections under CERCLA.

The following principles are an integral part of ASTM Designation E1527-13:
• "Uncertainty Not Eliminated - No environmental site assessment can wholly eliminate uncertainty regarding the potential for recognized environmental conditions in connection with a property. Performance of this practice is intended to reduce, but not eliminate, uncertainty regarding the potential for recognized environmental conditions in connection with a property, and this practice recognizes reasonable limits of time and cost." • "Not Exhaustive - All Appropriate Inquiries does not mean an exhaustive assessment of a property. There is a point at which the cost of information obtained or the time required to gather it outweighs the usefulness of the information and, in fact, may be a material detriment to the orderly completion of transactions. One of the purposes of this practice is to identify a balance between the competing goals of limiting the costs and time demands inherent in performing an environmental site assessment and the reduction of uncertainty about unknown conditions resulting from additional information."
• "Level of Inquiry is Variable-Not every property will warrant the same level of assessment.

Consistent with good commercial and customary practice, the appropriate level of environmental site assessment will be guided by the type of property subject to assessment, the expertise and risk tolerance of the user, and the information developed in the course of the inquiry."

1.2 Scope of Services
We performed the scope of services outlined in our Proposal No. LE-211188, dated April 16, 2021,with the exception that we did not review Sanborn fire insurance maps, as Environmental Data Resources, Inc. (EDR)indicated that there are none available for the Site or surrounding vicinity. The main components of the Phase I ESA and their objectives,as specified by the referenced standards,include the following:
• Physical Setting Review: we reviewed physical setting references for information concerning the topographic, geologic, and hydrogeologic characteristics of the Site and vicinity. Such information may be indicative of pathways (i.e., direction and/or extent) that a contaminant could migrate along in the event of a spill or release. • Regulatory Agency Records Review: we reviewed publicly available Federal, State, and local regulatory agency records for information regarding the use, storage, and disposal of hazardous substances and/or petroleum products at the Site and facilities and properties Project No.G2721-62-01 -2- May 12,2021

adjoining or within '/4 mile of the Site. Such records may identify RECs at or potentially affecting the Site.
• Site History Review: we reviewed information regarding the historical uses of the Site and adjoining and nearby facilities and properties back to the Site's and other properties' first use or 1940, whichever is earlier, that could have led to RECs on or near the Site. Historical sources reviewed included aerial photographs, topographic maps, and city directories. In addition, we conducted interviews with persons who were expected to be reasonably knowledgeable about historical and/or current conditions at and uses of the Site. • Site Reconnaissance: we performed a site reconnaissance to observe site conditions and activities for evidence of RECs. The site reconnaissance was for the Site only. We viewed offsite properties and features solely from the vantage of the Site and public thoroughfares.

1.3 Report Limitations
We prepared this report exclusively for the Client. The information obtained is only relevant for the dates of the records reviewed and the latest site visit. Therefore, the information contained herein is only valid as of the date of the report and may require an update after 180 days to reflect updated records and another reconnaissance to assess current site conditions.

The Client should recognize that this report is not a comprehensive site characterization and should not be construed as such. The findings and conclusions presented in this report are predicated on the site reconnaissance, information in the specified regulatory records, and information regarding the historical usage of the Site, as presented in this report. The Client should also understand that wetlands, asbestos-containing building materials, lead-containing paint, lead in drinking water, radon, mercury related to mining activities, methane, and mold surveys were not included in the scope of services for this report. Assessment for potential naturally occurring hazards such as asbestos and arsenic was also not included.

Therefore, the report should only be deemed conclusive with respect to the information obtained. No guarantee or warranty of the results of this assessment is implied within this report or any subsequent reports, correspondence or consultation, either express or implied. We strived to conduct the services summarized herein in accordance with the local standard of care in the geographic region at the time the services were rendered.

1.4 Data Gaps
A data gap is defined by ASTM Designation E 1527-13 as "a lack of or inability to obtain information required by this practice despite good faith efforts by the environmental professional to gather such information." Data gaps could include such things as insufficient historical information, the inability to interview persons with direct site knowledge (e.g., the owner(s), past owner(s), tenants, workers, etc.) or the lack of access to all parts of a site during the site reconnaissance. As indicated in Section Project No.G2721-62-01 -3- May 12,2021

1.2, we did not review Sanborn fire insurance maps for the Site and surrounding vicinity because there are none for the Site and vicinity. We do not consider this a significant data gap however, because of other available historical information we reviewed.

2. SITE DESCRIPTION
This section provides information regarding the location and physical characteristics of the Site including its size,topography, geologic, soil, and hydrogeologic conditions.

2.1 Location and Legal Description
The 9.2-acre Site is located northeast of the intersection of North Santa Fe Avenue and Camino Largo in Vista, California (Figure 1). The Site is depicted in the northeastern quarter of Section 12 of Township 11 South, Range 4 West, San Bernardino Base and Meridian on the United States Geological Survey's (USGS) San Marcos, California, 7.5-minute topographic map (USGS, 2018).

The San Diego County assessor's parcel number (APN) for the Site is 159-240-07. A copy of the parcel map is in Appendix A.

2.2 Site and Vicinity General Characteristics
The majority of the Site consists of undeveloped land that is currently occupied by a palm nursery.

The surrounding vicinity includes undeveloped open space and single-family residences. Figure 2 depicts the site boundaries and features and surrounding properties. Further site description is provided in Sections 2.4 and 6.

2.2.1 Topography
The topography of the site vicinity is characterized by gentle to moderate rolling hills that ultimately drain to the west. The USGS San Marcos, California, 7.5-minute topographic map (USGS, 2012), depicts the elevation at the Site as ranging from approximately 295 to 350 feet above mean sea level

2.2.2 Geologic and Soil Conditions
The Site is located in the Peninsular Ranges geomorphic province of Southern California (Norris and Webb, 1990). This geomorphic province extends approximately 900 miles from its northern terminus against the Transverse Ranges and Los Angeles Basin, south to the tip of Baja California. In general,the province is characterized by rugged mountains in Mesozoic igneous and metamorphic rocks to the east, with a dissected coastal plain on Cenozoic sediments to the west. The Peninsular Ranges vary in width from approximately 30 to 100 miles,and are traversed fault zones trending roughly northwest-southeast.

Project No.G2721-62-01 -4- May 12,2021

Information concerning the surficial geologic conditions at and in proximity to the Site from the Geologic Map of the Oceanside 30'X 60' Quadrangle, San Diego County, California (USGS, 2005) indicates that the Site is underlain by mid-Cretaceous mostly massive coarse-grained, light-gray hornblende-biotite tonalite, and late Holocene alluvial flood plain deposits which consist of unconsolidated sandy, silty,or clay-bearing alluvium.

The United States Department of Agriculture, Natural Resources Conservation Service, Web Soil Survey ( http://websoilsurvey.nres.usda.gov/app/HomePage.htm) indicates that site soil is Fallbrook sandy loam, Placentia sandy loam, Bonsall sandy loam, and Salinas sandy loam. These sandy loams are well drained and range from low to high infiltration rates.

2.2.3 Hydrologic and Hydrogeologic Conditions
Groundwater quality and occurrence information available from the California Department of Water Resources and the California State Water Resources Control Board(SWRCB) indicates that the Site is located in the Lower San Luis Hydrologic Area (903.10) of the San Luis Rey Hydrologic Unit (903.00). Groundwater in the Lower San Luis Hydrologic Area has existing beneficial use designations for municipal,agricultural, and industrial supply purposes (SWRCB,2018).

In an effort to assess local groundwater conditions, we reviewed reports available on the SWRCB's GeoTracker online database ( http://geotracker.waterboards.ca.gov) for nearby facilities with a groundwater monitoring well array. One groundwater monitoring well was installed approximately 1 mile southeast of the Site at 1450 North Santa Fe Avenue in 2013 related to assessment of County of San Diego Department of Environmental Health (DEH) Leaking Underground Storage Tank (LUST) case #DEH2O13-LSAM-000189. The depth to groundwater measured in this well was reported to be approximately 17-18 feet with groundwater flow estimated to be towards the southeast.

2.3 Current and Planned Uses of the Site
The Site is currently used for a palm nursery. The Client reported that they plan to develop the Site with a subdivision consisting of 48 single-family residences. Further description of the Site is provided in Section 6.

2.4 Descriptions of Structures, Roads, Other Improvements on the Site An irrigation reservoir was present in the northern central portion of the Site. Several storage containers and sheds are present throughout the Site. Overhead utilities extend across the central portion of the Site.

4.1.1 Site
The Site is listed on the CERS, ENVIROSTOR, and SCH databases. All of these listings are in reference to a school investigation that was proposed for the Site in September of 2003. The Vista Unified School District submitted an application to the DTSC to begin the Preliminary Endangerment Assessment for a proposed elementary school at the Site, but ultimately decided to no longer pursue Site acquisition.

Project No.G2721-62-01 -7- May 12,2021

4.1.2 Offsite Properties
No offsite properties within 1/8 mile (or 1/4 mile for LUST facilities) of the Site are identified in the regulatory databases reviewed. Distances reported by EDR may differ from actual distances.

4.1.3 Orphan Summary
EDR's Orphan Summary identifies properties with incomplete address information and therefore cannot be accurately plotted. One property is listed but because it is greater than one mile from the Site,it is not suspected of having caused an REC at the Site.

4.2 Additional Environmental Record Sources
This section summarizes information from additional, readily available environmental record sources regarding the Site and properties/facilities within one mile from the Site.

4.2.1 GeoTracker and EnviroStor Databases
We reviewed GeoTracker and the California Department of Toxic Substance Control's (DTSC) EnviroStor ( http://www.envirostor.dtsc.ca.gov/publics online databases for information regarding the Site and nearby properties/facilities that are within 1/4 mile of the Site. GeoTracker does not have information pertaining to the Site or any properties/facilities within 1/4 mile of the Site. EnviroStor does not have information pertaining to the Site any properties/facilities within 1/4 mile of the Site.

4.2.2 State of California Department of Conservation, Geologic Energy Management Division
We reviewed the California Geologic Energy Management Division (Ca1Gem) website ( https://maps.conservation.ca.gov/doggr/wellfinder) to evaluate the potential for existing/former oil, gas, or geothermal wells on the Site or properties proximal to the Site. Ca1Gem information indicates that no former or current wells are or were located within one mile of the Site.

4.2.3 County of San Diego Department of Agriculture, Weights and Measures We submitted a request to the County of San Diego, Department of Agriculture, Weights and Measures (DAWM), Pesticide Use Enforcement Division regarding possible use of restricted pesticides/herbicides at the Site. That office maintains such records for approximately 4 years. The DAWM indicated that no record of restricted pesticide/herbicide use was reported for the site APN for the period of 2017 through 2021.

Project No.G2721-62-01 -8- May 12,2021

4.2.4 San Diego Air Pollution Control District
We submitted a request to the San Diego Air Pollution Control District(APCD) for records pertaining to the Site. The APCD indicated that no records are on file for the site APN.

4.2.5 County of San Diego Department of Environmental Health We submitted a request to the DEH for records pertaining to the Site. The DEH indicated that no records are on file for the site APN.

4.2.6 San Diego Gas and Electric Company
A pole-mounted transformer is present on the Site.Documented discussions with San Diego Gas&Electric Company (SDG&E) representatives regarding transformers indicate that SDG&E has never specified polychlorinated biphenyl (PCB)-containing transformers for its electrical distribution system. Regardless, SDG&E has determined that some older(pre-1980s)mineral transformers were inadvertently contaminated with PCBs by the manufacturer. Based on a statistical sampling and testing program reportedly performed by SDG&E,it is unlikely that transformers found within its service area contain PCBs.

4.3 Previous Environmental Report
Following is a summary of a previous environmental report pertaining to the Site.

Vinje & Middleton Engineering, Inc. — Modified Phase I Environmental Site Assessment, Tentative Subdivision Map PC 6-05612-112, Camino Largo 8, N. Santa Fe Avenue, San Diego County, California, 92084 dated June 20, 2012.

Vinje & Middleton Engineering, Inc. performed a modified Phase I ESA at the Site in June 2012.

They found that the past use of the Site for agricultural purposes as well as a palm nursery represents a REC due to the potential for residue agricultural chemicals in the near surface soil. In addition, cumulative oil concentrations (motor oil, hydraulic oil, lubricating oil) were observed during their site reconnaissance in areas where dismantled vehicle chassis and a tractor were located.

Soil samples were collected and tested for OCPs, TPH, and arsenic. Laboratory results showed no detectable concentrations of OCPs, with arsenic concentrations ranging between 3.5 and 4.4 mg/kg, which is within the Southern California average background arsenic concentration of 12 mg/kg. Diesel concentrations ranged between non-detectable to 4,300 mg/kg, with cumulative oil concentrations ranging between non-detectable to 11,700 mg/kg. Vinje&Middleton Engineering, Inc. concluded that areas of soil staining beneath equipment is an REC and that the soil in those areas should be evaluated at a depth below grade to determine the vertical extent of contamination.

Project No.G2721-62-01 -9- May 12,2021

5. HISTORICAL USE
This section summarizes information we obtained from a variety of sources regarding the historical uses of the Site in an effort to identify those uses that could have led to RECs. The sources included historical aerial photographs,historical topographic maps,and an abstract of city directories provided by EDR.

5.1 Aerial Photographs
We reviewed historical aerial photographs for the years 1938, 1946, 1953, 1964, 1967, 1970, 1979, 1985, 1989, 2005, 2009, 2012 and 2016 (Appendix D) for indications of past land uses that had the potential to have impacted the Site through the use, storage or disposal of hazardous substances and/or petroleum products.The following table summarizes our observations of the Site and adjacent properties.

5.3 City Directories
EDR prepared an abstract of city directories including city, cross-reference, and telephone directories summarized in the EDR-City Directory Image Report dated April 22, 2021. The directories were reviewed at approximately 5-year intervals, if available, from 1971 to 2017. A copy of the EDR city directory abstract including information regarding offsite facilities is in Appendix F. Residents and businesses along North Santa Fe Avene are reported from 1971 to 2017, as well as a preschool. None of the listed residents, businesses, or schools reported by the EDR-City Directory are suspected of having caused an REC at the Site.

Project No.G2721-62-01 - 12- May 12,2021

6. SITE RECONNAISSANCE
This section summarizes observations of the Site and surrounding properties made during the site reconnaissance.

6.1 Methodology and Limiting Conditions
Troy Reist, Senior Geologist with Geocon, performed the site reconnaissance accompanied by the existing tenant of the Site, David Wendruck with Choice Nursery, on April 30, 2021. Mr. Reist performed the offsite survey by observing adjacent properties from the Site and adjacent public streets.

Weather on the day of the site reconnaissance was clear and the temperature was in the upper-70s.

Photographs of various site features and offsite properties are appended and Figure 2 illustrates selected site features.

6.2 General Site Setting
The Site is located in a ranch-style residential setting. North Santa Fe Avenue is adjacent to the west and Camino Largo is adjacent to the south of the Site.

6.3 Onsite Survey
The Site consists of mostly undeveloped land that is currently occupied by a palm nursery, identified as Choice Nursery (Photograph Nos. 1 through 6). Remnants of a former shed and an unutilized irrigation reservoir are present in the central portion of the site (Photographs Nos 7 and 8). A shed/trailer,utilized by the caretaker is present in the southwestern portion of the Site(Photograph No. 9). Several vehicles, an RV, farm/construction equipment, auto/machine parts and miscellaneous debris are located throughout the property (Photographs Nos 10 through 14). A storage trailer utilized for storing various irrigation parts and equipment, including fuel was present in the central portion of the site (Photograph No. 15). An empty storage container was located in the eastern portion of the Site (Photograph No 16). We observed a pole-mounted transformer in the central portion of the Site (Photograph No. 17).

We did observe some de minimis staining around the areas where vehicles, farm/construction equipment, auto/machine parts are stored(Photographs Nos. 18 and 19). An approximate 30 by 4-foot area of stained soil was observed directly beneath where a crane, utilized for the nursery, is located (Photograph No. 20), which is considered an REC based on the soil sample results discussed in Section 9.

Project No.G2721-62-01 - 13- May 12,2021

6.4 Offsite Survey
Properties within the site vicinity include:
• North: Single-family residences and open space (Photograph No. 21); • East: Extension of Camino Largo, beyond which are single-family residences (Photograph No. 22);
• South: Camino Largo, beyond which is open space and single-family residences (Photograph No. 23); and
• West: North Santa Fe Avenue,beyond which is a single-family residence(Photograph No.24).

We observed no evidence of RECs on the surrounding properties.

Project No.G2721-62-01 - 14- May 12,2021

7. INTERVIEWS
The current property owner, Frank Sohaei, reported via a site owner/occupant questionnaire (Appendix B) that the Site has been used as a palm nursery for at least 23 years. Mr. Sohaei reported that a reservoir exists on top of the western hill of the Site. Mr. Sohaei indicated that stained soil from parked equipment is present in portions of the Site.

Mr. David Wendruck with Choice Nursery indicated to Troy Reist during the Site investigation that no pesticides have been used for his palm nursery operation and was unaware of any hazardous substances or petroleum products that may have impacted the Site other than the observed stained areas where equipment has been parked.

Project No.G2721-62-01 - 15- May 12,2021

8. SUMMARY OF FINDINGS
The following table summarizes our findings and opinions regarding the Site, including known or suspect RECs, CRECs, HRECs, and de minimis environmental conditions. (REC/

NFA = No further action required at this time.

DM = De minimis condition where additional activities do not appear warranted at this time.

Soil staining around the existing crane parking area is considered an REC. The extent of the de minimis staining observed was limited to the areas of the Site where vehicles, farm/construction equipment, and auto/machine parts are stored. In addition, as described previously, the past use of the Site for agricultural purposes suggests that persistent pesticides may have been used on the Site.

However, the results of Vinje & Middleton Engineering, Inc's assessment indicates that the Site has not been impacted by OCPs or associated arsenic.

Project No.G2721-62-01 - 16- May 12,2021

9. PHASE II ESA
We performed a limited Phase II ESA to assess an area of the Site that was observed to have discolored soil where a crane, utilized for the palm nursery, has been parked for over 15 years according to Mr. Wendruck. Mr. Wendruck offered to move the crane so that we could further assess the area and collect representative soil samples from beneath the crane.

9.1 Scope of Investigation
The scope of the Phase 11 ESA consisted of the following tasks:
• Retaining Enthalpy Analytical, LLC, a state-certified laboratory, to perform laboratory analysis of soil samples and planned soil sample locations; • Collecting soil samples from the stained soil located beneath the crane parking area; • Performing laboratory analysis of soil samples; and
• Preparing this report describing the assessment and its findings.

9.2 Soil Sample Collection and Analysis
On April 30, 2021, we collected two discrete soil samples from the surface and 6-inches below existing grade from stained soil at the approximate location shown on Figure 2. The soil samples were collected using a decontaminated trowel then transferred into laboratory-provided 4-ounce jars. The jars were capped with Teflon-lined lids, labeled, and placed in a chilled cooler for transport to the laboratory under chain-of-custody protocol. The samples were analyzed for TPH and PCBs. Based on our observations while collecting and excavating the soil beneath the staining, the extent of the impacted soil appeared limited to the upper foot.

9.3 Results
A copy of the laboratory analysis report is in Appendix G and the results are summarized below.

TPH
Gasoline-range organics (GRO), were not detected at concentrations exceeding the laboratory reporting limits (RLs) in the samples. However, the following diesel-range organics (DRO) and oil- range organics (ORO)were detected at the following concentrations:

Project No.G2721-62-01 - 17- May 12,2021

• DRO was detected in both samples (S1-0' and S1-0.5') at 13,000 and 490 milligrams per kilogram(mg/kg),respectively,which exceeds the San Francisco Bay Regional Water Quality Control Board Environmental Screening Levels (ESLs) for DRO in residential soil of 260 mg/kg.
• ORO was detected in both samples(51-0' and 51-0.5') at 13,000 and 370 mg/kg,respectively, which exceeds the ESL for ORO in Sample S1-0' for residential soil of 12,000 mg/kg.

PCBs
The PCB Arolchlor-1260 was detected in Sample S1-0.5' at a concentration of 0.057 mg/kg, which does not exceed the Hero Note 3 Department of Toxic Substances Control Screening Levels for residential soil of 0.24 mg/kg.

Project No.G2721-62-01 - 18- May 12,2021

10. CONCLUSIONS AND RECOMMENDATIONS
We have performed a Phase I ESA, in general conformance with the scope and limitations of ASTM E 1527-13, of the 9.2-acre Site in Vista, California. The San Diego County APN for the Site is 159-240-

07. Our limited Phase II that consisted of collecting soil samples beneath the crane parking area confirmed the presence of diesel and oil-range organics and PCBs. The concentrations in the samples exceeded the applicable regulatory health risk-based screening levels for diesel and oil-range organics, which is considered an REC. The impacted soil (less than 5 cubic yards),which is confined to the upper foot of a 30 x 4-foot area, should be excavated and properly disposed of prior to development.

If additional significant soil staining or petroleum odors are observed during grading observations, Geocon Incorporated should be contacted to observe and possibly sample areas of potential impact to determine if further action is warranted. Additionally, any undocumented subsurface structures or areas of apparent contamination encountered during site redevelopment activities including septic tanks, USTs,wells, etc. should be properly abandoned/removed in accordance with San Diego County regulatory requirements.

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable(orphan)sites are not considered in the foregoing analysis.

ENVIROSTOR:The Department of Toxic Substances Control's (DTSC's) Site Mitigation and Brownfields Reuse Program's(SMBRP's) EnviroStor database identifes sites that have known contamination or sites for which there may be reasons to investigate further. The database includes the following site types: Federal Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State Superfund;Voluntary Cleanup;and School sites. EnviroStor provides similar information to the information that was available in CalSites, and provides additional site information, including, but not limited to, identification of formerly-contaminated properties that have been released for reuse, properties where environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk characterization information that is used to assess potential impacts to public health and the environment at contaminated sites.

A review of the ENVIROSTOR list,as provided by EDR,and dated 01/25/2021 has revealed that there is TC6456522.2s EXECUTIVE SUMMARY 7

SEMS-ARCHIVE: Superfund Enterprise Management System Archive TC6456522.2s Page GR-2

GOVERNMENT RECORDS SEARCHED / DATA CURRENCY TRACKING
SEMS-ARCHIVE(Superfund Enterprise Management System Archive)tracks sites that have no further interest under the Federal Superfund Program based on available information.The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available.Archived sites have been removed and archived from the inventory of SEMS sites.Archived status indicates that,to the best of EPA's knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List(NPL),unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time.The decision does not necessarily mean that there is no hazard associated with a given site;it only means that.based upon available information,the location is not judged to be potential NPL site.

EPA WATCH LIST: EPA WATCH LIST
EPA maintains a"Watch List'to facilitate dialogue between EPA,state and local environmental agencies on enforcement matters relating to facilities with alleged violations identified as either significant or high priority.Being on the Watch List does not mean that the facility has actually violated the law only that an investigation by EPA or a state or local environmental agency has led those organizations to allege that an unproven violation has in fact occurred.Being on the Watch List does not represent a higher level of concern regarding the alleged violations that were detected,but instead indicates cases requiring additional dialogue between EPA,state and local agencies-primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

EDR HIGH RISK HISTORICAL RECORDS
EDR Exclusive Records
EDR MGP: EDR Proprietary Manufactured Gas Plants
The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants(manufactured gas plants) compiled by EDR's researchers.Manufactured gas sites were used in the United States from the 1800's to 1950's to produce a gas that could be distributed and used as fuel.These plants used whale oil,rosin,coal,or a mixture of coal,oil,and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar(oily waste containing volatile and non-volatile chemicals),sludges,oils and other compounds are potentially hazardous to human health and the environment.The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly,serving as a continuous source of soil and groundwater contamination.

EDR's GeoCheck Physical Setting Source Addendum is provided to assist the environmental professional in forming an opinion about the impact of potential contaminant migration.

Assessment of the impact of contaminant migration generally has two principle investigative components:

1. Groundwater flow direction, and

2. Groundwater flow velocity.

Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata.

TC6456522.2s Page A-1

GEOCHECK® - PHYSICAL SETTING SOURCE SUMMARY

GROUNDWATER FLOW DIRECTION INFORMATION
Groundwater flow direction for a particular site is best determined by a qualified environmental professional using site-specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other sources of information, such as surface topographic information, hydrologic information, hydrogeologic data collected on nearby properties, and regional groundwater flow information (from deep aquifers).

TOPOGRAPHIC INFORMATION
Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property,what downgradient sites might be impacted.

HYDROLOGIC INFORMATION
Surface water can act as a hydrologic barrier to groundwater flow. Such hydrologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property,what downgradient sites might be impacted.

HYDROGEOLOGIC INFORMATION
Hydrogeologic information obtained by installation of wells on a specific site can often be an indicator of groundwater flow direction in the immediate area. Such hydrogeologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property,what downgradient sites might be impacted.

GEOCHECK® - PHYSICAL SETTING SOURCE SUMMARY

GROUNDWATER FLOW VELOCITY INFORMATION
Groundwater flow velocity information for a particular site is best determined by a qualified environmental professional using site specific geologic and soil strata data. If such data are not reasonably ascertainable, it may be necessary to rely on other sources of information, including geologic age identification, rock stratigraphic unit and soil characteristics data collected on nearby properties and regional soil information. In general, contaminant plumes move more quickly through sandy-gravelly types of soils than silty-clayey types of soils.

GEOLOGIC INFORMATION IN GENERAL AREA OF TARGET PROPERTY Geologic information can be used by the environmental professional in forming an opinion about the relative speed at which contaminant migration may be occurring.
