Phase I Environmental Site Assessment
EXECUTIVE SUMMARY
This report presents the findings of a Phase I Environmental Site Assessment (ESA) for the
property located at 800 Grand Avenue, Carlsbad, California (Figure 1, Vicinity Map). The
subject property is currently developed with three two-story commercial buildings and an
asphalt-paved parking lot.
Rincon Consultants performed a reconnaissance of the subject property on September 14, 2016.
The purpose of the reconnaissance was to observe existing subject property conditions and to
obtain information indicating the presence of recognized environmental conditions in
connection with the subject property. With the exception of small quantities of paint and
typical maintenance supplies observed in the maintenance area to the northwest of Building B,
the use, storage or disposal of hazardous materials on the subject property was not observed
during the site reconnaissance.
The subject property is located in an area that is primarily composed of residential and
commercial land uses. Properties in the vicinity of the subject property include single-family
homes, multi-family residences, a dentist office, and commercial properties. The current
adjacent land uses are described in Table 1 and depicted on Figure 3, Adjacent Land Use Map.
Environmental Data Resources, Inc. (EDR) was contracted to provide a database search of public
lists of sites that generate, store, treat or dispose of hazardous materials or sites for which a release
or incident has occurred. The EDR search was conducted for the subject property and included
data from surrounding sites within a specified radius of the property. The subject property and
adjacent properties were not listed in any of the databases searched by EDR. Two nearby
properties were listed on release databases searched by EDR. However, these properties were
located cross gradient of the subject property. Therefore, based on the closed case status, the
soils only nature of the release and/ or the location of these release sites cross gradient of the
subject property, the properties are not expected to impact the subject property.
Historical sources reviewed as part of the Phase I ESA include aerial photographs, topographic
maps, and city directories. The photos, maps, and city directories reviewed indicate that the
subject property was vacant land from at least 1893 to 1901. By 1939, the subject property was
developed with at least one single structure on the northwestern portion of the property. From
1946 to 1967 the subject property was developed with multiple residential structures. Since at
least 1979, the subject property has been developed with three commercial structures along the
southeastern portion of the subject property and an asphalt-paved parking area on the
northwestern portion of the property. In general, the subject property resembles its present-day
configuration since at least 1979. City directories indicate that the subject property has been
used for commercial purposes since at least 1976, and possibly as early as 1950. City directories
also indicate that the subject property was developed with apartments and used for residential
purposes since at least 1965.
Based on the findings of this Phase I ESA, it is our opinion that no recognized environmental
conditions were identified for the subject property.

PHYSICAL SETTING SOURCES
Topography
The current USGS topographic map (San Luis Rey, 2012) indicates that the subject property is
situated at an elevation of about 65 feet above mean sea level with topography sloping to west
southwest.
Geology and Hydrogeology
Site Geology
According to the US Geologic Map (Oceanside Quadrangle, 2007), the subject property is
underlain by old paralic deposits, Units 6-7.
Regional Groundwater Occurrence and Quality
During the preparation of this Phase I ESA, we reviewed the California State Water Resources
Control Board's (SWRCBs) online Geotracker database to determine depth to groundwater in
the vicinity of the site. According to Case Closure Summary, 920 Carlsbad Village Drive, Carlsbad,
California prepared by County of San Diego Department of Environmental Health (DEH) Site
Assessment and Mitigation (SAM) and dated April 13, 1998, groundwater was encountered
between approximately 10 and 13 feet below ground surface (bgs) and is reported to flow to the
southwest. This property is located approximately 400 feet southeast of the subject property.
STANDARD ENVIRONMENTAL RECORD SOURCES
Environmental Data Resources, Inc. (EDR) was contracted to provide a database search of
public lists of sites that generate, store, treat or dispose of hazardous materials or sites for which
a release or incident has occurred. The EDR search was conducted for the subject property and
included data from surrounding sites within specified radii of the property. A copy of the EDR
report, which specifies the ASTM search distance for each public list, is included as Appendix B.
As shown on the attached EDR report, federal, state and county lists were reviewed as part of
the research effort. Please refer to Appendix B for a complete listing of sites reported by EDR
and a description of the databases reviewed.
The Map Findings Summary, included in the EDR report, provides a summary of the databases
searched, the number of reported facilities within the search radii, and whether the facility is
located onsite or adjacent to the subject property. The following information is based on our
review of the Map Findings Summary and the information contained in the EDR report.

800 Grand Avenue, Carlsbad, California
Phase I Environmental Site Assessment
Subject Property
The subject property was not listed on any of the regulatory databases reviewed.
Offsite Properties
Offsite properties listed by EDR fall under two general categories of databases: those reporting
unauthorized releases of hazardous substances (e.g., LUST, National Priority List [a.k.a.
Superfund sites], and corrective action facilities), and databases of businesses permitted to use
hazardous materials or generate hazardous wastes, for which an unauthorized release has not
been reported to a regulatory agency.
Rincon reviewed the EDR Radius Map and select detailed listings to evaluate their potential to
impact the subject property, based on the following factors:
• Reported distance of the facility from the subject property
• The nature of the database on which the facility is listed, and/ or whether the facility was
listed on a database reporting unauthorized releases of hazardous materials, petroleum
products, or hazardous wastes
• Reported case type (e.g., soil only, failed UST test only)
• Reported substance released (e.g., chlorinated solvents, gasoline, metals)
• Reported regulatory agency status (e.g., case closed, "no further action")
• Location of the facility with respect to the reported groundwater flow direction
(discussed in the Geology and Hydrogeology section of this report)
Facilities/properties that were interpreted by Rincon to be of potential environmental concern
to the subject property, based on one or more of the factors listed above, are summarized in
Table 2. In accordance with ASTM, contamination migration pathways in soil, groundwater,
and soil vapor were considered in our analysis of offsite properties of potential environmental
concern.

Regulatory agency information reviewed for the listings in the table above are summarized in
the Additional Environmental Record Sources section of this report.
Orphan Listings
EDR reported three orphan or unmapped site listings, which EDR is unable to plot due to
insufficient address information. Based on Rincon' s review of the limited address information
or site descriptions for the orphan listings, one of the listings, the Carlsbad Bumsite, was
identified to be located at Carlsbad Village Drive. Records for the Carlsbad Burnsite were
requested from the San Diego County DEH. According to the records, the Carlsbad Bumsite
was formerly located near the intersection of Carlsbad Village Drive and Concord Street, which
is approximately 1.90 miles east-northeast of the subject property. Therefore, this property is not
expected to impact the subject property.
ADDITIONAL ENVIRONMENTAL RECORD SOURCES
Review of Agency Files
As a follow-up to the database search, Rincon reviewed regulatory information for facilities
within the specified search radii that were interpreted to have the potential to impact the subject
property, based on one or more factors previously discussed (e.g., distance, open case status,
up-gradient location, soil vapor migration).
The following is a summary of our review of regulatory information obtained from review of
online sources (e.g., SWRCB GeoTracker database, DTSC Envirostor database) and/or files
requested from the applicable regulatory agency, as described below.
Subject Property
The subject property was not listed in any of the databases searched by EDR.
Adjacent Properties
Adjacent properties were not listed in any of the databases searched by EDR.
Nearby Release Sites
Two nearby properties were listed in databases searched by EDR:
• Gasco Service Station #511/Valero/AMPM #511/High Desert Oil Co. Inc located at 920
Carlsbad Village Drive: This property is located approximately 400 feet to the southeast of
the subject property and is listed on GeoTracker, as well as the SWEEPS UST, HMMD San
Diego, SAN DIEGO CO. SAM, UST, EMI, HIST UST, and LUST databases searched by
EDR. The leaking underground storage tank (LUST) database listing is indicative of an
unauthorized release at the property. According to the EDR report and GeoTracker, the
property experienced a release of gasoline and waste oil to soil and groundwater in March
1994 during tank closure activities. A total of approximately 342 cubic yards of impacted
soil were removed from the property and three groundwater monitoring wells were
installed. One year of groundwater monitoring reported that human health, human safety,
and groundwater quality were not at risk. The case was closed in May 1998. Based on the
r 9
800 Grand Avenue, Carlsbad, California
Phase I Environmental Site Assessment
closed case status, and the reported direction of groundwater flow to the southwest (cross
gradient of the subject property), the release from this property is not expected to impact
the subject property.
• Village 76 Car Waslvf osco Corp #2705723/Unocal Service Station #7 located at 880
Carlsbad Village Drive: This property is located approximately 400 feet to the southeast of
the subject property and is listed on GeoTracker, as well as the HMMD San Diego, EMI,
LUST, SWEEPS UST, SAN DIEGO CO. SAM, SLIC, HIST CORTESE, and EDR Historical
Auto Station databases searched by EDR. The LUST and Spills, Leaks, Investigation and
Oeanup (SLIC) database listings are indicative of an unauthorized release at the property.
According to the EDR report and Geo Tracker, multiple releases are associated with this
property:
o Case H12427-001: Both EDR and Geotracker indicate that a release of diesel to soil
occurred at this property in October 1985 during tank closure activities. The
impacted soil was reportedly excavated and disposed offsite and the case was
closed in September 1989. Based on the closed case status and the soils only nature
of the release, the former release is not expected to impact the subject property.
o Case H12427-002: Both EDR and GeoTracker indicate that a release of gasoline
occurred at this property on July 5, 1996; the media impacted was not reported.
However, the case was closed on July 20, 1996. Therefore, based on the closed case
status and the direction of groundwater flow to the southwest ( cross gradient of the
subject property), the former release is not expected to impact the subject property.
o Case H12427-003: Both EDR and GeoTracker indicate that a release of diesel and
gasoline impacted soil and groundwater at this property in October 2008. Five soil
borings were completed and soil and groundwater samples were collected.
Concentrations of total petroleum hydrocarbons (lPH) were detected in both soil
and groundwater samples. Remediation activities included removal of
approximately 535 tons of impacted soil. Five groundwater monitoring wells were
subsequently installed and two rounds of groundwater sampling events indicated
that no benzene and low concentrations of methyl tertiary butyl ether (MTBE) were
detected. Approximately 13 cubic yards of lPH-impacted soil above 100 milligrams
per kilogram (mg/kg) were estimated to remain at the property. However, soil and
groundwater contamination was reported to not pose a significant threat to human
health or the environment. Therefore, based on the closed case status and the
reported direction of groundwater flow to the southwest (cross gradient of the
subject property), the former release is not expected to impact the subject property.
KNOWN OR SUSPECT CONTAMINATED RELEASE SITES WITH
POTENTIAL VAPOR MIGRATION
The EDR report was reviewed to identify nearby known or suspect contaminated sites that have
the potential for contaminated vapor originating from the nearby site to be migrating beneath
the subject property. Based on the ASTM E 2600-10, Standard Guide for Vapor Encroachment
Screening on Property Involved in Real Estate Transactions, the following minimum search
distances were initially used to determine if contaminated soil vapors from a nearby known or
suspect contaminated site have the potential to be migrating beneath the subject property:

Based on our review of the documents listed above, it appears that the southeastern adjacent
property was vacant land from at least 1893 to 1901, developed with a street followed by a
single structure in 1939, and developed with a street followed by multiple structures from 1946
to present day. The southeastern adjacent property generally resembles its present-day
configuration since approximately 1979.
Southwestern Adjacent Property
Based on our review of the documents listed above, it appears that the southwestern adjacent
property was vacant land from at least 1893 to 1901, developed with a single structure in 1939,
and developed with multiple structures from 1946 to present day. The southwestern adjacent
property generally resembles its present-day configuration since approximately 1990.
Gaps in Historical Sources
Several gaps of greater than 5 years were identified in the historical records reviewed: from
1901 to 1939, from 1939 to 1946, and from 1953 to 1964. These gaps are considered insignificant
because the subject property use appears to be similar prior to and following the gaps.
INTERVIEWS
Rincon Consultants provided a questionnaire regarding the subject property and surrounding
· areas to the owner of the property. The purpose of the questionnaire was to identify current and
historical subject property conditions and to obtain information indicating the presence of
recognized environmental conditions in connection with the property.

INTERVIEW WITH OWNER/SITE MANAGER
Mr. Edmond Shehab, the current property owner, completed the property owner questionnaire.
Mr. Shehab indicated the following:
• The subject property is currently used for commercial offices.
• The northern adjacent property is currently developed with a triplex (residential).
• The eastern adjacent property is currently used as a dentist office.
• The western adjacent property is currently developed with commercial offices and
apartments.
• Mr. Shehab has owned the subject property for 35 years.
• The onsite buildings were building approximately 70 years ago.
• No hazardous waste is generated at the subject property.
In addition, Mr. Shehab indicated that there are no industrial drums, evidence of fill dirt, pits,
ponds or lagoons, sumps, clarifiers, or solvent degreasers, stained soil, storage tanks, vent
pipes, fill pipes, or access ways, stained surfaces, transformers, capacitors, or hydraulic
equipment, records indicating the presence of PCBs, or records indicating the presence of
pesticides/herbicides on the subject property.
Mr. Shehab indicated that he is not aware of any pending, threatened, or past litigation or
administrative proceedings relevant to hazardous substances or petroleum products in, on, or
from the property. In addition, he is not aware of any notice from any government entity
regarding any possible violation of environmental laws or possible liability relating to
hazardous substances or petroleum products.
INTERVIEWS WITH LOCAL GOVERNMENT OFFICIALS
Based on the fact that the subject property and adjacent properties were not listed in any of the
databases searched by EDR, no records were requested for these properties.
However, one orphan listing, Carlsbad Burnsite, was listed on the Solid Waste Facility /Landfill
database. Based on the unknown location of the property and the nature of the listing, records
for this property were requested from the County of San Diego DEH. Information available
from those records is included in the Review of Agency Files section above.

Rincon did not attempt to interview neighboring property owners or others as part of this
research effort.

EVALUATION
CONCLUSIONS & RECOMMENDATIONS
Rincon has performed a Phase I ESA in general conformance with the scope and limitations of
AS1M E 1527-13 for the property located at 800 Grand Avenue, Carlsbad, California. This
assessment has not revealed evidence of RECs in connection with the subject property.
Based on the findings of this Phase I ESA, no additional assessment is recommended.
Based on the construction of the onsite structures sometime between 1970 and 1979, and the
results of the previous asbestos and LBP surveys conducted at the subject property, both
asbestos and LBP are present onsite. Although not considered a REC for the purposes of this
Phase I ESA, renovation or demolition of the onsite structures would require asbestos and LBP
Surveys, development of and operations and maintenance plan, and abatement.
DEVIATIONS
Deviations from AS1M E 1527-13 Practice were not encountered during the completion of this
Phase I ESA.
