JOB NO. 04-8849
I. SUMMARY
Geotechnical Exploration Inc. (GEI) performed a Phase I Environmental Site
Assessment (ESA) of the subject property between 7 March and 31 March 2005.
The property is located in the east quadrant of the City of Carlsbad, which is in
northwest San Diego County. The property is irregularly shaped and occupies an
area of 43.19 acres. Historically, this part of the city was used for agriculture, with
various property owners growing dry, row-crop produce or ornamental plants. The
subject property was undeveloped until the early 1980s when it was cleared for
agricultural use. The parcel has remained in intermittent agricultural use until
present. Currently the site exists as fallow agricultural land.
The following sections summarize GEI's independent conclusions based on our best
professional judgment and the information and data available to us at the time of
the assessment. Factual information regarding operations, conditions, and test
data provided by the client, owner, or their representative has been assumed to be
correct and complete.
1.1 Conclusions
The subject property was undeveloped and unused between 1955 and the early
1980s. It was cleared of native vegetation in the early 1980s and has been in
agricultural use intermittently since that time. There are no overt indicators of
agricultural chemical usage on-site such as patchy vegetation that might suggest
Rancho Milagro Development Job No. 04-8849
Carlsbad, California Page 2
the presence of herbicides in the soil or areas of unusually dense growth that might
suggest high levels of fertilizers in the soil. Two soil samples were collected for
chemical analysis to determine if pesticide or herbicide residues are present in the
soil. The results of these analyses will be provided in a letter report, once the
analyses are completed. There are no structures onsite and therefore testing for
asbestos containing material, lead-based paint, or radon gas was not required.
The site is largely cleared of vegetation with patches of non-native vegetation
remaining. The Agua Hedionda Creek streambed runs through the southwest side
of the property. This riparian habitat is considered a sensitive biological resource
by state and federal resource agencies and is subject for Sunny Creek. No
indicators of hazardous materials usage or disposal were observed and the site is
free ofany significant accumulation of solid waste.
GEI's review of the adjacent properties did not reveal any significant environmental
issues that could affect the value of the property or constrain development.
1.2 Recommendations
No environmental concerns that would require further investigation were discovered
during the course of this ESA. It is suggested that the property owner periodically
contact the San Diego County Department of Environmental Health to check the
regulatory status on the farmland adjacent to the subject property.
1.3 Proiect Staff
The following individuals conducted the field work and prepared the report for this
Phase I Environmental Site Assessment.

II. METHODOLOGY AND REPORT LIMITATIONS
The purpose of an ESA is to evaluate the environmental status of the subject
property and surrounding area with the intent of identifying any existing or
potential features that could constrain development of the property or represent a
significant environmental liability. An ESA is primarily a screening tool designed to
identify environmental "red flags." GEI often collects soil screening samples from
properties that have been in agricultural use to provide an indication of the
presence of agricultural chemical residues. Two such samples were collected and
the analytical results are pending. If potential issues or constraints are identified, a
Phase II Environmental Site Investigation (ESI) involving more extensive sample
collection and analysis may be required to quantify the significance of impact to the
property.
This report is intended solely for the use of the Client in connection with any near
term real estate transaction involving this property. This report is not to be quoted,
in whole or in part, or otherwise relied upon for any other purpose. This report may
be released at the Client's discretion for 6 months following issuance. After 6
months, GEI should be contacted to determine if conditions on the ground have
changed sufficiently to require revision of the report.
It should be emphasized that this ESA focuses on past and present practices that
could represent a potential liability to the owner or buyer of the property under
current environmental laws and regulations. The findings of this assessment are
apparent from the data gathered and the degree of access to the property
Rancho Milagro Development Job No. 04-8849

permitted for the PS site visit. Environmental sampling and chemical analysis was
not conducted as part of this assessment.
2.1 Assessment Activities
All GEI ESAs are fully compliant with the requirements of ASTM Standard E 1527-00
and current professional standards. As per these requirements, PS performed a
visual inspection of the property and the surrounding area, an analysis of aerial
photographs and maps, and a review of files maintained by the City ofCarlsbad and
the County of San Diego, as well as interviews with key individuals. In addition,
county, state and federal databases were searched for records of hazardous
materials violations on the subject property and all locations within one mile of the
property.
The Phase I Assessment for the subject site included the following tasks:
1. Survey of the property to observe current use of the site and adjacent
properties, for indications of potential contamination and/or the presence of
hazardous materials.
2. Interview knowledgeable sources regarding current and previous uses of the
subject property and adjacent properties.
3. Review of state/federal lists to assess the potential for hazardous materials
generators or leaking underground storage tanks within the vicinity of the
subject property.
4. Review of existing documentation, as available, regarding prior
investigations, events, or conditions on the site and in the immediate vicinity
<IHI
Rancho Milagro Development Job No. 04-8849
Carlsbad, California Page 5
relating to spills, discharges, or other activities that could represent
environmental concerns or indicate the presence of hazardous material.
5. Search Sanborn Insurance Maps for the subject site and immediate
surrounding area.
6. Review historical aerial photographs of the subject site and immediate
surrounding area.
7. Review topographic maps of the subject site and immediate surrounding
area.
8. Preparation of a report documenting findings, recommendations and
professional opinions regarding observed or suspected environmental
m constraints.
2.2 Regulatory Agency Data Review
The regulatory agency report provided is based on an evaluation of the data
collected and compiled by a contracted data research company. The report is
based on a radius search that focuses on both the subject and neighboring sites
that may impact the subject property. Neighboring sites listed in governmental
environmental records are identified within a specific search distance. The search
distance varies depending upon the particular government record being checked.
The search is designed to meet the requirements of the current industry approach
and the ASTM Standard E 1527-00. The information provided is assumed to be
correct and complete.

2.3 Report Limitations
This report is prepared solely for the use of the Client in accordance with ASTM
standards. Our professional services have been performed, our findings obtained
and our recommendations prepared in accordance with customary principles and
practices in the field of environmental science. This company is not responsible for
the independent conclusions, opinions or recommendations made by others based
on the field exploration presented in this report.
It should be noted that all surficial environmental assessments are inherently
limited in the sense that conclusions are drawn and recommendations developed
from information obtained from limited research and site evaluation. A
comprehensive subsurface survey was not performed as part of this study.
Subsurface conditions may differ from the conditions implied by the surface
observations. Additionally, the passage of time may result in a change in the
environmental characteristics at this site and surrounding properties.
It must be noted that no investigation can absolutely rule out the existence of any
hazardous materials at a given site. This assessment has been based upon prior
site history and observable conditions and activities. Existing hazardous materials
and contaminants can escape detection using these methods.
The work performed in conjunction with this assessment and the data developed
are intended as a description of available information at the dates and location
given. This report does not warrant against future operations or conditions, nor
does it warrant against operations or conditions present of a type or at a location
not investigated. In addition, this report is not intended as a regulatory agency
compliance/safety audit or for the purpose of ensuring that all applicable permits
and/or operating procedures are current and/or appropriate.

3.4 Hvdrology
The California Regional Water Quality Control Board (RWQCB) assigns beneficial
uses to all water bodies in the state as means of preserving and/or improving the
water quality of the receiving waters of the state. The subject property is located in
the Los Monos Hydrologic Subarea, which is a part of the larger Agua Hedionda
Hydrologic Area with the Carlsbad Hydrologic Unit. The RWQCB has designated the
following beneficial uses for groundwater in the Los Monos Subarea: agricultural
water supply, municipal water supply industrial water supply, process water and
freshwater habitat (reference #3).
The western edge of the property lies within the lOO-year floodway and floodplain.
The portion of the property east of the lOO-year floodplain lies within the 500-year
floodplain. A floodplain map is provided in Appendix A to define the limits of these
areas (reference #4). There is no record of permitted wells on the site according to
State of California regional ground water maps, thus depth to groundwater at the
site is unknown. Groundwater movement is to the southwest following surface
drainage patterns. The overall groundwater gradient is west toward the Pacific
Ocean (reference #5).
3.5 Current Use
The property is currently in agricultural use, although at the time of this survey the
land was being fallowed. The property is totally cleared of vegetation, except along
Agua Hedionda Creek, which supports willow riparian vegetation. Given the
absence of activity, it is considered unlikely that any conditions attributable to the
present use of the property pose a significant environmental impact or constraint to
development ofthe property.

3.5.1 Adjacent Properties
Land use on the adjacent properties is described in the table below.
Direction Land use
North Farm land
Northeast Farm land
Northwest Farm land and equine stable
South Farmland and low density residential
Southeast Undeveloped land.
Southwest Undeveloped land
East Farm land
West Residential development - moderate density
The property is in an area that 50 years ago was either undeveloped or in
agriculture. Much of the area to the east is still in active agricultural or equine use.
A planned residential community was constructed to the west of the site within the
last five years. The future extension of College Boulevard will cross above the
north end ofthe parcel.
It is our opinion that the adjacent properties do not represent an environmental
constraint to the subject property. The adjacent farmland could potentially be a
source of agricultural chemical residues. The property owner is advised to monitor
the status of agricultural chemical use on adjacent properties through periodic
contact with the San Diego Department of Health Services.
3.6 Prior Use of Property
Research into the site history and past use of a property represents a crucial
component of any due diligence environmental assessment. Historical uses which
may have caused environmental impacts on the property are often neglected, and
Rancho Milagro Development
Carlsbad, California
Job No. 04-8849
Page 11
may be associated with previous occupation by service stations, automotive
businesses, dry cleaners, metal plating operations, manufacturers, farms or
landfills.
The subject property was undeveloped and existed as natural habitat until the mid-
1980s, when it was cleared and plowed for agricultural use. No other uses of the
property were identified during the course of this review. It has never been used
for industrial, residential or community use in the past 50 years. Given the
agricultural use of the property it was considered prudent to collect soil samples for
analysis for agricultural chemicals. The results of these analyses will be provided in
a separate letter report once they become available.
3.6.1 Historical Aerial Photograph Review
A review of the San Luis Rey USGS map of 1968, Rev. 1975 was performed along
with an examination of historical aerial photographs dating back to 1960, using the
archives of the County of San Diego Cartographic Services Department (reference
#5), Aerial Fotobank, Inc.(reference #6), Terra Server Image Viewer (reference
#7) and GlobeXplorer Aerial Imagery (reference #8). The photos reviewed
included the years 1960, 1967, 1974, 1989, 1995, 2002 and 2004.

A review of the earliest photos (1960 and 1967) showed the subject site's natural,
undisturbed topography, with essentially no disturbance to the native groundcover.
No structures or other evidence of human construction was observed on the site.
Although large areas of natural, undisturbed groundcover were also shown outside
and near the perimeter of the site, adjacent properties to the east and west (north
of Agua Hedionda Creek) were shown cleared of their natural ground cover and
graded for agricultural operations. The nearest structures in 1960 and 1967
appeared to be an agricultural related complex located immediately west of the
site, across an unpaved utility road that generally borders the property boundary.
Additional small structures were also shown located along the north side of Agua
Hedionda Creek, immediately adjacent to the subject site's eastern perimeter. The
nearest significant non-agricultural activity was the McClellan Palomar Airport,
located approximately a mile and a half south ofthe site.
The first sign of significant residential and commercial development near the site
was evident on the 1974 photo, which showed the residential community bordered
by Calaveras Drive and El Camino Real approximately V2-mile west of the site,
along Agua Hedionda Creek. Also, nearby commercial development was shown
initiated east of El Camino Real by the grading and construction of Faraday Avenue
and associated business structures located approximately y2-mile south of the site.
These developments are also shown on the 1968 USGS map (revised 1975).
Throughout this period, the subject site remained undisturbed.
The 1989 photo showed an increase in the density of commercial development
south of the site, along El Camino Real, as well as residential community
development approximately y2-mile northeast of the site. An increase in
agricultural operations was also evident in the immediate vicinity, including the
center portion the site, which was shown cleared and graded for agriculture.

Rancho Milagro Development Job No. 04-8849
Carlsbad, California Page 13
The 1995 photo showed the site and adjacent properties to be essentially in their
most recent configuration of growing fields and associated operations structures
and utility roads. An initial alignment of Sunny Creek Road was also shown along
the south side of Agua Hedionda Creek, just outside the subject site's southwest
border. The land between Sunny Creek Road and El Camino Real, however,
remained undeveloped. The 2002 photo showed the initial grading and
construction of the residential community located on this land area, including the
current alignments of Sunny Creek Road, College Boulevard, and the complex of
residential streets serving this development. The 2004 photo showed the site and
adjacent properties to be in today's configuration.
Based on the photo/map review, the current use and configuration of the site and
vicinity was developed into agricultural uses prior to 1960, with subsequent
residential and commercial uses developed from the 1970s into the present day.
Residential development nearest the site is less than 5 years old and has only
slightly modified the original topographic condition of the area.
There were no observable current or prior uses that would warrant a significant
environmental concern. Nevertheless, contamination or any impacts on the site or
from adjacent and nearby land uses cannot be precluded by the historical review
alone. No further historical investigation is recommended at this time.
3.6.2 Sanborn Maps
No historical Sanborn maps are available for the subject area. The lack of Sanborn
mapping suggests that the area was not significantly developed with industrial or
commercial land uses in the past.
Rancho Milagro Development Job No. 04-8849
Carlsbad, California Page 14
IV. ENVIRONMENTAL HAZARDS ASSESSMENT
A variety of environmental issues and hazards can constrain development at a
given site. These potential issues include chemical hazards such as the presence of
asbestos, agricultural chemical residues or PCBs and biological constraints such as
the presence of wetlands and endangered species.
4.1 Description of Asbestos Hazards
Asbestos can be found in almost any building material and is routinely found in
insulation, blown acoustic ceiling finishes, flooring and roofing materials. Less
commonly used as a building material since the mid-1970s, asbestos is still in use
or distribution in certain materials such as flooring and roofing. Friable asbestos is
considered more hazardous than non-friable asbestos because it can become more
easily airborne and thus is more likely to enter the respiratory system, where it can
lead to serious health problems. Inhalation of airborne fibers is believed potentially
to lead to lung diseases and cancer.
4.1.1 Asbestos at the Subject Site
There are no structures on the property and thus no testing for asbestos containing
materials (ACM) was conducted. There are no asbestos related concerns associated
with use of this property.
4.2 Description of PCB Hazards
Polychlorinated biphenyls (PCBs) have been used in hydraulic fluids and dielectric
(insulating) fluids in transformers, capacitors, and fluorescent light ballasts. PCB-
containing fluids were used mainly in indoor locations to minimize the possibility of
fire if electrical equipment overheated. PCBs were also used in transformers
Rancho Milagro Development Job No. 04-8849
Carisbad, California Page 15
mounted on overhead power supply lines. The primary hazard associated with
PCBs are fire-related damage to PCB-filled equipment. The PCBs vaporize and may
be converted to dioxins and furans that are toxic through ingestion and inhalation.
A secondary potential hazard is posed by spills and leaks that can contaminate soil
and groundwater. PCBs are toxic through ingestion, but do not represent a
significant inhalation hazard due to their low volatility.
4.2.1 PCBs at the Subject Property
No PCB-containing equipment was observed on the subject site. No overhead
power lines with potentially PCB containing transformers were observed anywhere
on or adjacent to the property. No ground mounted transformers were observed on
or adjacent to the property.
4.3 Description of Leaking Underground/Above-ground Storage Tank
Hazards
Underground and above-ground storage tanks (USTs & ASTs) are found on many
residential and commercial properties. They are used for storing fuel, waste oils,
solvents, and other waste and hazardous materials. The principal hazard from
USTs and ASTs is leakage of contents due to corrosion of the tanks or lines. The
leakage may result in migration onto the subject property and/or other properties
of the stored material via the media of soil or groundwater. Soil and groundwater
contaminated by the contents of USTs/AGTs can constitute health hazards. Clean-
up of contaminated soil and/or groundwater and subsequent litigation is often
costly.
Rancho Milagro Development Job No. 04-8849
Carisbad, California Page 16
4.3.1 USTs/AGTs at the Subject Property
No USTs or AGTs were observed on the subject property during the site survey. No
USTs or AGTs were identified during the review of government records, historical
site searches, or during interviews with the property owner, his agent and neighbor.
4.4 Description of Hazardous Materials Activity
Migration of chemical contaminants is the primary risk associated with the use or
disposal of hazardous materials. Skin rashes, central nervous system disorders and
possibly cancer could potentially result from inhalation of gases and vapors or
drinking contaminated water. Clean-up of contaminated conditions and subsequent
litigation can be very costly.
In the course of the environmental assessment, government records are checked
for evidence of waste disposal at or near the site and an on-site survey is
performed to detect any overt sign of hazardous materials use or disposal. In
addition, historical Sanborn Insurance maps and/or aerial photographs of the site
are reviewed for evidence of industrial operations or waste disposal activities.
4.4.1 Hazardous Materials/Waste Activity at the Site
No evidence of hazardous materials usage was observed during the site survey or
uncovered in the review of government records and historical aerial photographs.
It is considered highly unlikely that there are any hazardous materials related
impacts present on the subject property.
<IHI
Rancho Milagro Development Job No. 04-8849
Carisbad, California Page 17
4.5 Additional Hazards
The presence of significant quantities of paints, fertilizers, soil amendments, and
maintenance chemicals are examples of every day materials that can pose a
hazard/risk to the environment and constrain development of the property. The
following paragraphs discuss these miscellaneous hazard types as they relate to the
subject property.
4.5.1 Property Housekeeping
The property is undeveloped, largely vegetated with non-native species and free of
solid waste. There are no general concerns relating to the physical condition of the
property. No further action or investigation is needed.
4.5.2 Drinking Water
Drinking water can be contaminated with lead, petroleum products, solvents, and
any other chemical substances that migrate into the soil or groundwater table.
Municipal water departments are required to treat and analyze potable water
supplies prior to public use to assure the water meets current government
standards for drinking water quality.
The property is not currently hooked up to the local municipal water supply. When
the property is developed, water will be provided by the CMWD. Staff at the CMWD
indicated that their water supply is purchased from the San Diego County Water
Authority which, in turn, purchases water from the Los Angeles Metropolitan Water
District which supplies a blend of California Water Project and Colorado River water.
According to CMWD the water supplied to the subject property meets or exceeds
all USEPA drinking water standards, including the standard for lead content
(reference #9).
<IHI
Rancho Milagro Development Job No. 04-8849
Carlsbad, California Page 18
No further action or investigation ofthe domestic water supply is necessary.
4.5.3 Urea Formaldehyde Foam Insulation
Urea formaldehyde foam insulation (UFFI) was used during the 1970s and eariy
1980s to re-insulate buildings with little or no existing insulation. Urea and
formaldehyde were mixed with a foaming agent and then injected into the walls of
buildings, A problem can ensue if excess formaldehyde is present in the mixture.
Toxic formaldehyde gas can slowly escape from the foam and permeate the
building, UFFI can off-gas for up to a year after installation and can cause eye,
nose, and throat irritation, disturbed sleep, and allergic reactions.
There are no structures onsite and thus no UFFI present.
4.5.4 Review of Other Hazards and Constraints
During the course of the site survey, no evidence of waste pits, ponds, clarifiers,
drywells, landfills, or illegal dumping activity was observed on or adjacent to the
subject property.
4.5.5 Wetlands
Agua Hedionda Creek crosses the western portion of the property. This creek
constitutes sycamore oak riparian woodland, a habitat type considered sensitive by
state and federal resource protection agencies. In addition, patches of coastal sage
scrub habitat were observed on north facing slopes above the riparian habitat.
Coastal sage scrub is another type of sensitive habitat protected by state and
federal regulation.
Rancho Milagro Development Job No. 04-8849
Carisbad, California Page 19
4.6 Earthquake Hazard
Earthquakes, ground shaking and liquification are the primary geotechnical
constraint to development in Southern California. The nearest known active
earthquake faults are the nearby Rose Canyon fault system (approximately 15
miles to the southwest) and the Coronado Bank and Elsinore fault systems which lie
approximately 30 miles southwest and 35 miles northeast ofthe site, respectively.
The Rose Canyon Fault is considered to be capable of causing a 7.5-magnitude
earthquake and considered micro-seismically active, although no significant recent
earthquake is known to have occurred on the fault. Investigative work on faults
believed to be part of the Rose Canyon Fault Zone, in downtown San Diego and in
Rose Canyon, has identified offset Holocene sediments. Confirming that Holocene
(geologically recent) displacement has occurred on the Rose Canyon Fault. This
indicates that this fault zone, previously considered "potentially active," should
now be classified as an "active" fault (reference #10).
While the subject parcel would experience moderate to severe ground shaking in
the event of a major earthquake, the potential for direct ground rupture in the
vicinity of the property is considered extremely unlikely and ground conditions are
not conducive to liquefaction. No evidence of other unstable geologic conditions
was observed on or adjacent to the property during the site walk.
V. REGULATORY AGENCY DATA REVIEW
GEI contacted the San Diego County Department of Environmental Health Services

Carisbad, California Page 20
usage and disposal databases was performed using the computerized resources of
Environmental FirstSearch (EFS) (reference #11).
A detailed description of the state, federal and local hazardous materials databases
searched by EFS is provided in Appendix C. The locations of any sites identified in
the database search are plotted on the quarter mile and one mile radius maps that
are also included in Appendix C. Facilities identified in the database review can be
divided into two broad categories:
1. Permitted users of hazardous materials, operators of underground or above
ground storage tanks, and registered disposers of hazardous waste.
2. Sites listed for unauthorized release of hazardous materials, leaking
underground storage tanks, or violation of hazardous materials handling
regulations.
The subject property is not listed in either of these categories. There is no record
of hazardous materials, use, disposal or violation related to the subject property,
5.1 Federal and State Listed Hazardous Waste Sites
Federal and state hazardous waste site listings were reviewed for this assessment,
e.g., NPL, CERCLIS, NFRAP, LUST, etc. By cross-referencing name, address, and
zip code, we conclude that the subject property is not a listed site. The area search
for nearby sites listed in these databases identified various sites individually
outlined in the Regulatory Agency Data Report Findings included in Appendix C.
Information concerning listed sites considered to have the potential to impact the
site is included in each of the database sections that follow.

Notice of Disclaimer
Due to the limitations, constraints, inaccuracies and incompleteness of govemment information and computer mappii^ data currently available to
TRACK Info Services, certain conventions have been utilized in preparing the locations of all federal, state and local agency sites residing in
TRACK Info Services's databases. All EPA NPL and state landfill sites are depicted by a rectangle approximating their location and size. The
boundaries of the rectangles represent the eastem and westem most longitudes; the northem and southem most latitudes. As such, the mapped areas
may exceed the actual areas and do not represent the actual boundaries of these properties. All other sites are depicted by a point representing their
approximate address location and make no attempt to represent the actual areas of the associated property. Actual boundaries and locations of
individual properties can be found in the files residing at the agency responsible for such information.
Waiver of Liability
Although TRACK Info Services uses its best efforts to research the actual location of each site, TRACK Info Services does not and
can not warrant the accuracy of these sites with regard to exact location and size. All aulhorized users of TRACK Info Services's services
proceeding are signifying an imderstanding of TRACK Info Services's searching and mapping conventions, and agree to waive any and all
liability claims associated with search and map results showing incomplete and or inaccurate site locations.

CALIFORNIA DATABASES (DB) AND SOURCES
SMBRPD / CAL SITES: DB TYPE = STATE (STATE SITES)or OTHER(Other Sites)
Source: The CAL EPA, Depart. Of Toxic Substances Control
Phone:(916) 323-3400
The California Department of Toxic Substances Control (DTSC) has developed an
electronic database system with information about sites that are known to be
contaminated with hazardous substances as well as information on uncharacterized
properties where further studies may reveal problems. The Site Mitigation and
Brownfields Reuse Program Database (SMBRPD), also known as •CalSites,D is used
primarily by DTSCDs staff as an informational tool to evaluate and track
activities at properties that may have been affected by the release of hazardous
substances.
The SMBRPD displays information in six categories. The categories are:
1. CalSites Properties (CS)
2. School Property Evaluation Program Properties (SCH)
3. Voluntary Cleanup Program Properties (VCP)
4. Unconfirmed Properties Needing Further Evaluation (RFE)
Please Note: FirstSearch Reports list the above sites as DB Type (STATE).
5. Unconfirmed Properties Referred to toother Local or State Agency (REF)
6. Properties where a No Further Action Determination has been made (NFA)
Please Note: FirstSearch Reports list the above sites as DB Type (OTHER).
Each Category contains information on properties based upon the type of work
taking place at the site. For example, the CalSites database is now one of the
six categories within SMPBRD and contains only confirmed sites considered as
posing the greatest threat to the public and/or the potential public school
sites will be found within the School Property Evaluation Program, and those
properties undergoing voluntary investigation and/or cleanup are in the
Voluntary Cleanup Program.
CORTESE: DB TYPE = STATE (STATE SITES)

Phone: (916) 445-6532
Pursuant to Government Code Section 55962.5, the Hazardous Waste and Substances
Sites List has been compiled by Cal/EPA, Hazardous Materials Data Management
Program. The CAL EPA Dept. of Toxic Substances Control com.piles information from
subsets of the following databases to make up the CORTESE list:
1. The Dept. of Toxic Substances Control; contaminated or potentially
contaminated hazardous waste sites listed in the CAL Sites database. Formerly
kno-vsm as ASPIS are included (CALSITES formerly known as ASPIS) .
2. The California State Water Resources Control Board; listing of Leaking
Underground Storage Tanks are included (LT/-UK)
3. The California Integrated Waste Management Board; Sanitary Landfills which
have evidence of groundwater contamination or known migration of hazardous
materials (formerly WB-LF, now AB 3750).
Note: Track Info Services collects each of the above data sets individually and
lists them separately in the following First Search categories in order to
provide more current and comprehensive information: CALSITES: SPL, LTANK: LUST,

California. The types of facilities found in this database include landfills,
transfer stations, material recovery facilities, composting sites,
transformation facilities, waste tire sites, and closed disposal sites. For more
information on individual sites call the number listed above.
Flease Note: This database contains poor site location Infozmation for many
sites in the First Search reports; therefore, it may not be possible to locate
or plot some sites in First Search reports.

Phone:(916) 227-4365
The State Water Resources Control Board maintained the Waste Management
Unit Database System (WMUDS). It is no longer updated. It tracked
management units for several regulatory programs related to waste
management and its potential impact on groundwater. Two of these
programs (SWAT & TPCA) are no longer on-going regulatory programs as
described below. Chapter 15 (SC15) is still an on-going regulatory
program and information is updated periodically but not to the WMUDS
database. The WMUDS System contains information from the following
agency databases: Facility, Waste Management Unit (WMU), Waste
Discharger System (WDS), SWAT, Chapter 15, TPCA, RCRA, Inspections,
Violations, and Enforcement's.
Note: This database contains poor site location information for many
sites in the First Search reports; therefore, it may not be possible to
locate or plot some sites in First Search reports.

The Above Ground Petroleum Storage Act became State Law effective
January 1, 1990. In general, the law requires owners or operators of
AST's with petroleum products to file a storage statement and pay a fee
by July 1, 1990 and every two years thereafter, take specific action to
prevent spills, and in certain instances implement a groundwater
monitoring program. This law does not apply to that portion of a tank
facility associated with the production oil and regulated by the State
Division of Oil and Gas of the Dept. of Conservation.
SWEEPS / FIDS STATE REGISTERED UNERGOROUND STORAGE TANKS: DB TYPE = US
Source: CAl EPA Dept of Toxic Substances Control
Phone:(916)227-4404
Until 1994 the State Water Resources Control Board maintained a database
of registered underground storage tanks statewide referred to as the
SWEEPS System. The SWEEPS UST information was integrated with the CAl
EPA's Facility Index System database (FIDS) which is a master index of
information from numerous California agency environmental databases.
That was last updated in 1994 . Track Info Services included the UST
information from the FIDS database in its First Search reports for
historical purposes to help its clients identify where tanks may
possibly have existed. For more information on specific sites from
individual paper files archived at the State Water Resources Control
Board call the niunber listed above.
CUPA DATABASES DESCRIPTIONS
(DB TYPE = US (UNDERGROUND STORAGE TANKS)
DEFINITION OF A CUPA: A Certified Unified Program Agency (CUPA) is a
local agency that has been certified by the CAL EPA to implement six
state environmental programs within the local agency's jurisdiction.
These can be a county, city, or JPA (Joint Powers Authority) . This
program was established under the amendments to the California Health
and Safety Code made by SB 1082 in 1994.
A Participating Agency (PA) is a local agency that has been designated
by the local CUPA to administer one or more Unified Programs within
their jurisdiction on behalf of the CUPA. A Designated Agency (DA) is an
agency that has not been certified by the CUPA but is the responsible
local agency that would implement the six unified programs until they
are certified.
Please Note: Track Info Services, LLC collects and maintains information
regarding Underground Storage Tanks from majority of the CUPAS and
Participating Agencies in the State of California. These agencies
typically do not maintain nor release such information on a uniform or
consistent schedule; therefor, currency of the data may vary. Please
look at the details on a specific site with a UST record in the First
Search Report to determine the actual currency date of the record as
provided by the relevant agency. Numerous efforts are made on a regular
basis to obtain updated records.

RE: Rancho Milagro Greenhouse Gas (GHG) Screening Letter
The purpose of this Green House Gas (GHG) screening assessment is to show that the
proposed 19-unit single family residential development and 6 open space lots within
the City of Carlsbad would be in substantial conformance to the California Global
Warming Solutions Act of 2006 (AB32), which requires that by 2020 the state's
greenhouse gas emissions be reduced to 1990 levels or roughly a 28.3% reduction
from business as usual.
Regulatory Standards
AB32 in its entirety can be viewed at http://www.arb.ca.gov/cc/ab32/ab32.htm. The
pertinent sections of this law are identified below:
Section 38560.5 states;
(A) On or before June 30, 2007, the state board shall publish and make available to
the public a list of discrete early action greenhouse gas emission reduction
measures that can be implemented prior to the measures and limits adopted
pursuant to Section 38562.
(B) On or before January 1, 2010, the state board shall adopt regulations to implement
the measures identified on the list published pursuant to subdivision (a).
Section 38562 states:
(A) On or before January 1, 2011, the state board shall adopt greenhouse gas emission
limits and emission reduction measures by regulation to achieve the maximum

technologically feasible and cost-effective reductions in greenhouse gas emissions
in furtherance of achieving the statewide greenhouse gas emissions limit, to
become operative beginning on January 1,2012.
(B) In adopting regulations pursuant to this section and Part 5 (commencing with
Section (38570), to the extent feasible and in furtherance of achieving the
statewide greenhouse gas emissions limit, the state board shall do all of the
following:
(1) Design the regulations, including distribution of emissions allowances
where appropriate, in a manner that is equitable, seeks to minimize costs and
maximize the total benefits to California, and encourages early action to reduce
greenhouse gas emissions.
(2) Ensure that activities undertaken to comply with the regulations do not
disproportionately impact low-income communities.
(3) Ensure that entities that have voluntarily reduced their greenhouse gas
emissions prior to the implementation ofthis section receive appropriate credit
for early voluntary reductions.
(4) Ensure that activities undertaken pursuant to the regulations complement,
and do not interfere with, efforts to achieve and maintain federal and state
ambient air quality standards and to reduce toxic air contaminant emissions.
(5) Consider cost-effectiveness of these regulations.
(6) Consider overall societal benefits, including reductions in other air
pollutants, diversification of energy sources, and other benefits to the economy,
environment, and public health.
(7) Minimize the administrative burden of implementing and complying with
these regulations.
(8) Minimize leakage.
(9) Consider the signiticance ofthe contribution of each source or category of
sources to statewide emissions of greenhouse gases.
a. In furtherance of achieving the statewide greenhouse gas emissions limit,
by January 1, 2011, the state board may adopt a regulation that establishes
a system of market-based declining annual aggregate emission limits for
sources or categories of sources that emit greenhouse gas emissions,
applicable from January 1, 2012, to December 31, 2020, inclusive, that the
state board determines will achieve the maximum technologically feasible

and cost-effective reductions in greenhouse gas emissions, in the
aggregate, from those sources or categories of sources,
b. Any regulation adopted by the state board pursuant to this part or Part 5
(commencing with Section 38570) shall ensure all ofthe following:
1. The greenhouse gas emission reductions achieved are real, permanent,
quantifiable, verifiable, and enforceable by the state board.
2. For regulations pursuant to Part 5 (commencing with Section 38570), the
reduction is In addition to any greenhouse gas emission reduction
otherwise required by law or regulation, and any other greenhouse gas
emission reduction that othenA/ise would occur.
3. If applicable, the greenhouse gas emission reduction occurs over the
same time period and is equivalent in amount to any direct emission
reduction required pursuant to this division.
The Climate Change Scoping plan lists the discrete early action greenhouse gas
emission reduction measures, which will be enforceable January 1, 2010 (Climate
Change Scoping Plan - California Air Resource Board - December 2008). The Board
adopted nine discrete early action items which identified within the Scoping plan
however, none of the discretionary measures relate to the project at hand. The nine
measures are identified in Table 1 on the following Page.
Additionally, as stated in section 38562-A of AB 32, the state board shall adopt
greenhouse gas emission limits and emission reduction measures before January 1,
2011 and enforce these measures starting January 1, 2012. Currently, greenhouse gas
emission limits for residential project such as the proposed project, have not been
adopted, however. Section 38562-B-3 encourages projects to voluntarily identify
greenhouse gas reductions and receive appropriate credit for early voluntary
reductions.
The California Air Pollution Control Officers Association (CAPCOA) published a white
paper which suggested screening criteria of 900 metric tons of GHGs. Jurisdictions
such as the County of San Diego, City of San Diego, and County of Riverside have
either accepted or adopted these initial screening thresholds. Projects creating more
than 900 metric tons of GHGs generally are considered significant and require
reduction measures from business as usual with goals ranging from 25% to 33% but
would depend on the jurisdiction.

Greenhouse Gasses contributed from the proposed project are Carbon Dioxide (CO2),
Methane (CH4), and Nitrous Oxide (N2O). For the purposes of analysis, both CH4 and
N2O can be converted to an equivalent amount of CO2 (C02e) by multiplying the
calculated levels of CH4 and N2O by a Global Warming Potential (GWP). The U.S.
Environmental Protection Agency publishes GWPs for various GHGs and reports that
the GWP for CH4and N2O is 21 and 310, respectively.
C02e emissions generated from the project include vehicular offsite contributions as
well as onsite area emissions from combustion activities utilizing natural gas and
indirect electricity use. However, the largest source of C02e is produced from the
projects vehicular trip generation. The best way to reduce these emission levels would
be to reduce vehicular miles traveled, reduce fossil fuel burning vehicles and improve
the fuel efficiency of vehicles.

It can be expected that government agencies through mandates and regulations will
effectively reduce the carbon footprint of vehicles in the future. For example, the
Energy Independence and Security Act of 2007 will require automakers to boost fleet
wide gas mileage averages from the current 25 mpg to 35 mpg by 2020.
Project Related Construction Emissions
Air quality impacts related to construction will be calculated using the latest
URBEMIS2007 air quality model, which was developed by ARB. URBEMIS2007 has
been approved by SDAQMD and the City for construction emission calculations.
URBEMIS incorporates emission factors from the EMFAC2007 model for on-road
vehicle emissions and the OFFROAD2007 model for off-road vehicle emissions.
Because CO2 emissions from construction only occur at the beginning of a project,
emissions will be averaged over a 30-year period. This recommendation was based on
proposals from South Coast Air Quality Management District in 2008.
The project engineer expects to have grading complete in approximately two months,
trenching complete in ten days, building and paving complete in four months Table 2
below shows the expected timeframes for the construction process at the proposed
project location.
Utilizing the URBEMIS 2007 model (attached at the end of this report), we find that
that total construction emissions during construction of the project will produce 176.66
tons CO2. Given the fact that the total emissions will ultimately contribute to 2020
cumulative levels, it is acceptable to average the total construction emission over a 30
year period which would yield roughly 5.89 tons per year or 5.34 metric tons per
year(SCAQMD 2008. A summary of the construction emissions is shown in Table 3
below.

Project Related Offsite Vehicular Emissions
C02e generated from offsite vehicular sources from the project can be calculated by
utilizing the assumption that the average one-way trip distance could be as high as
10-miles and that there could be as many as 190 daily trips. Simply multiplying 190
daily trips by an average 10-mile per trip yields approximately 1,900 miles per day.
Multiplying the 1,900 miles per day by 365 days yields 693,500 miles per year. Based
on the project vehicle miles traveled, the fleet wide average fuel efficiency of 25 MPG,
the project would be expected to burn approximately 27,740 gallons of fuel each day.
Utilizing methodologies within the California Climate Action Registry General Reportinq
Protocol Version 3.1- Januarv 2009 rcCARGRPV3.iy CO2, CH4, and N20from vehicular

Project Related GHG Emissions
Based upon our analysis of daily operational activities for the proposed development,
the proposed project would most likely produce a total of approximately 372 metric
tons of C02e per year as can be seen in Table 7. This is below the CAPCOA 900
Metric Ton screening threshold and no mitigation would be required. Therefore, the
project would be considered compliant with AB32 and no further analysis is warranted.

Conclusions
Based upon the findings for the proposed development, the daily operational activities
and construction emissions are anticipated to produce an average of approximately
372 metric tons of C02e per year. Which is well below the CAPCOA 900 Metric Ton
screening threshold and the project would be considered compliant with AB32. If you
