EXECUTIVE SUMMARY
This analysis has been completed in order to quantify Greenhouse Gas (GHG) emissions from
the project site and was prepared according to guidelines established within the california
Global Warming Solutions Act of 2006 -Assembly Bill 32 (AB32), Senate Bill 97 (SB97), and
california Environmental Quality Act (CEQA). Greenhouse Gasses analyzed in this study are
carbon Dioxide (CO2), Methane (CH4), and Nitrous Oxide (N20). To simplify greenhouse gas
calculations, both CH4 and N20 are converted to equivalent amounts of CO2 and are identified
as C02e.
The project proposes the construction of an 11 unit residential development within a 3.13 acre
site. All phases (i.e. grading, paving and construction) of the proposed Project are anticipated
to start in January 2015 and would be completed later that year.
The proposed project will emit GHGs directly through the burning of carbon-based fuels such as
gasoline and natural gas as well as indirectly through usage of electricity, water and from the
anaerobic bacterial breakdown of organic solid waste. The proposed project would only
generate approximatelx 267.72 Metric Tons of C02e each year under business as usual, which is
below the strictest screening thresholds under the california Air Pollution Control Officers
Association's (CAPCOA) recommendations of 900 Metric Ton per year. Given this no impacts or
remedial mitigation measures would be required.
Regulatory measures such as the AB 1493 Pavley rules and California's Low Carbon Fuel
Standards will further reduce these emissions as the programs develop further and would be
independent of the project applicant. Therefore, the project conforms to the goals of AB 32
and would not result in any direct or cumulative impacts.

1.0 INTRODUCTION
1.1 Purpose of this Study
The purpose of this Green House Gas Assessment (GHG) is to show conformance to the
california Global Warming Solutions Act of 2006 -Assembly Bill 32 (AB32) and Senate. Bill
97 (5897). AB32 requires that by 2020 the state's greenhouse gas emissions be reduced to
1990 levels and SB97 a "companion" bill directed amendments to the california
Environmental Quality Act (CEQA) statute to specifically establish that GHG emissions and
their impacts are appropriate subjects for CEQA analysis. Should impacts be determined,
the intent of this study would be to recommend suitable design measures to bring the
project to a level considered less than significant.
1.2 Project Location
The proposed project is located within the City of Carlsbad, CA. More specifically, the
project site is located north of Mccauley Lane and south of Buena Vista Way within the City
of carlsbad CA. Access to the project site would be taken from both Buena Vista Way and
Mccauley Lane. A general project vicinity map is shown in Rgure 1-A on the following
page.
1.3 Project Setting
The proposed project would consist of 11 single-family residences. The existing site
conditions are characterized as disturbed land that is currently utilized as a nursery. Both
residential and agricultural uses surround the project site. A project site plan is shown in
Figure 1-B on Page 3 of this report.

2.0 EXISTING ENVIRONMENTAL SETTING
2.1 Understanding Greenhouse Gasses
Greenhouse gases such as water vapor and carbon dioxide are abundant in the earth's
atmosphere. These gases are called "Greenhouse Gases" because they absorb and emit
thermal infrared radiation which acts like an insulator to the planet. Without these gases,
the earth ambient temperature would either be extremely hot during the day or blistering
cold at night. However, because these gases can both absorb and emit heat, the earth's
temperature does not sway too far in either direction.
Over the years as human activities require the use of burning fossil fuels stored carbon is
released into the air in the form of CO2 and to a much lesser extent CO. Additionally, over
the years scientist have measured this rise in carbon Dioxide and fear that it may be
heating the planet too. Additionally, it is thought that other greenhouse gases such as
Methane and Nitrous Oxide are to blame.
Greenhouse Gasses of concern as analyzed in this study are carbon Dioxide (CO2), Methane
(CH4), and Nitrous Oxide (N20). To simply greenhouse gas calculations, both CH4 and N20
can be converted to an equivalent amount of CO2 or C02e. C02e is calculated by multiplying
the calculated levels of CH4 and N20 by a Global Warming Potential (GWP). The U.S.
Environmental Protection Agency publishes GWPs for various GHGs and reports that the
GWP for CH4 and N20 is 21 and 310, respectively.
2.2 Existing Setting
The Project site lies within a mostly disturbed flat lot with agricultural uses. Land uses
surrounding the project site is residential. The average elevations over the site ranges from
between 185 to 195-feet above mean sea level.
2.3 Climate and Meteorology
Climate within the San Diego Air Basin (SDAB) area often varies dramatically over short
geographical distances with cooler temperatures on the western cost gradually warming to
the east as prevailing winds from the west heats up. Most of southern ·california is
dominated by high-pressure systems for much of the year, which keeps carlsbad mostly
sunny and warm. Typically, during the winter months, the high pressure system drops to
the south and brings cooler, moister weather from the north.
4
Ldn Consulting, Inc. 10/13/14 1486-02 Buena Vista GHG Study
It is common for inversion layers to develop within high-pressure areas, which mostly define
pressure patterns over the SDAB. These inversions are caused when a thin layer of the
atmosphere increases in temperature with height. An inversion acts like a lid preventing
vertical mixing of air through convective overturning.
Meteorological trends within the Carlsbad area generally experience daytime highs ranging
between 660F in the winter to approximately 79°F in the summer with August usually being
the hottest month. Median temperatures range from approximately SS°F in the winter to
approximately 72°F in the summer. The average humidity is approximately 66% in the
winter and about 73% in the summer (Source: http://www.city-data.com/city/carlsbad-
california.html). carlsbad usually receives approximately 10.4-inches of rain per year with
February being the wettest month (Source: http://www.weather.com
/weather/wxclimatology /monthly /graph/USCA0182).

3.0 CLIMATE CHANGE REGULATORY ENVIRONMENT
3.1 AB 1493 (Pavley) Standards
Assembly Bill 1493 was california's first bill which was approved by the Governor in 2002
and was designed to reduce greenhouse gases within the state of california. It required the
State Board do develop and adopt motor vehicle regulations to cost effectively reduce
greenhouse gasses by January 1, 2005 and start enforcing them a year later. Furthermore,
the state board shall develop and adopt regulations that achieve the maximum feasible and
cost-effective reduction of greenhouse gas emissions from motor vehicles.
3.2 Regulatory Standards (Assembly Bill 32)
The Global Warming Solutions Act of 2006 (AB 32), requires that by 2020 the State's
greenhouse gas emissions be reduced to 1990 levels or roughly a 28.3% reduction.
Significance thresholds have not been adopted but are currently being discussed. AB 32 is
specific as to when thresholds shall be defined. The pertinent Sections are referenced within
Part 4 of AB 32 Titled Greenhouse Gas Emissions Reductions are shown below:
Section 38560.5 (b) states:
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.
(BJ 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.
6
Ldn Consulting, Inc. 10/13/14 1486-02 Buena Vista GHG Study
3. Ensure that entities that have voluntarily reduced their greenhouse gas emissions prior
to the implementation of this 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 significance of the contribution of each source or category of sources to
statewide emissions of greenhouse gases.
(CJ 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.
(D)Any regulation adopted by the state board pursuant to this part or Part 5 (commencing
with Section 38570) shall ensure all of the 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 otherwise 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.
3.3 Regulatory Standards (Senate Bill 97)
SB 97 requires the Office of Planning and Research (OPR) to prepare and transmit to the
Resources Agency, guidelines and directed amendments to the CEQA statute specific.ally for
the mitigation of greenhouse gas emissions or the effects of greenhouse gas emissions.
7
Ldn Consulting, Inc. 10/13114 1486-02 Buena Vista GHG Study
3.4 AB 1493 (Pavley Standards)
AB 1493 regulations are similar to CAFE Standards however are expected to produce a
Greenhouse Gas Benefit greater to that of the CAFE Standard and would be expected to
double the amount of GHGs saved under CAFE. The Pavley rules or also referred to as
california Standards are designed to regulate GHG emissions while the federal standards are
aimed at reducing the nation's fuel consumption.
Under Pavley starting with vehicles produced in 2009, manufactures have the flexibility in
meeting california standards through a combination of reducing tailpipe emissions of carbon
Dioxide, Nitrous Oxide, Methane and hydrofluorocarbons from vehicle air conditions
systems. Furthermore, the california standards are estimated to increase fuel efficiency to
43 miles per gallon by 2020. The 2020 reductions are based on a more stringent emission
limit than the current california Standards, called the Pavley 2 Rule, as set forth in the
california Climate Action Plan and committed to by the ARV in its Early Action Measures
under AB32.
3.5 Energy Independence and Security Act of 2007
The Energy Independence and Security Act of 2007 (P.L. 110-140, H.R. 6) is an energy
policy law adopted by congress which consists mainly of provisions designed to increase
energy efficiency and the availability of renewable energy. The law will require automakers
to boost fleet wide gas mileage averages from the current 25 mpg to 35 mpg by 2020,
which will reduce energy needs by 28.5%. This fleet wide average is known as the
Corporate Average Fuel Economy (CAFE) standard.
3.6 Executive Order S-01-07
Executive Order 5-01-07 was signed by Governor Arnold Schwarzenegger in January 2007
and is effectively known as the Low carbon Fuel Standard or LCFS. The executive order
seeks to reduce the carbon intensity of california's passenger vehicle fuels by at least 10%
by 2020. The LCFS will require fuel providers in california to ensure that the mix of fuel
they sell into the california market meet, on average, a declining standard for GHG
emissions measured in C02e grams per unit of fuel energy sold.
3.7 california Environmental Quality Act (CEQA) Significance Thresholds
As directed by SB 97, the Natural Resources Agency adopted Amendments to Title 14
Division 6 Chapter 3 CEQA Guidelines for greenhouse gas emissions on December 30, 2009.
On February 16, 2010, the Office of Administrative Law approved the Amendments, and
8
Ldn Consulting, Inc. 10/13/14 1486-02 Buena Vista GHG Study
filed them with the Secretary of State for inclusion in the california Code of Regulations. The
amendments became effective on March 18, 2010. The pertinent Sections are shown below:
Section 15064.4 -Determining the Significance of Impacts from Greenhouse Gas
(A) The determination of the significance of greenhouse gas emissions calls for a careful
judgment by the lead agency consistent with the provisions in Section 15064. A lead
agency should make a good-faith effort, based to the extent possible on scientific and
factual data, to describe, calculate or estimate the amount of greenhouse gas
emissions resulting from a project. A lead agency shall have discretion to determine, in
the context of a particular project, whether to:
1. Use a model or methodology to quantify greenhouse gas emissions resulting from a
project, and which model or methodology to use. The lead agency has discretion to
select the model or methodology it considers most appropriate provided it supports its
decision with substantial evidence. The lead agency should explain the limitations of
the particular model or methodology selected for use; and/or
2. Rely on a qualitative analysis or performance-based standards.
(8) A lead agency should consider the following factors, among others, when assessing the
significance of impacts from greenhouse gas emissions on the environment:
1. The extent to which the project may increase or reduce greenhouse gas emissions as
compared to the existing environmental setting;
2. Whether the project emissions exceed a threshold of significance that the lead agency
determines applies to the project.
3. The extent to which the project complies with regulations or requirements adopted to
implement a statewide, regionai or local plan for the reduction or mitigation of
greenhouse gas emissions. Such requirements must be adopted by the relevant public
agency through a public review process and must reduce or mitigate the project's
incremental contribution of greenhouse gas emissions. If there is substantial evidence
that the possible effects of a particular project are still cumulatively considerable
notwithstanding compliance with the adopted regulations or requirements, an EIR
must be prepared for the project.
General Questions recommended within the environmental checklist are:
(a) Will the project generate greenhouse gas emissions, either directly or indirectly, that
may have a significant impact on the environment?
(b) Will the project conflict with an applicable plan, policy or regulation adopted for the
purpose of reducing the emissions of greenhouse gases?

3.8 Scoping Plan Measures
In response to AB 32, california Air Resource Board (ARB) developed the Climate Change
Scoping Plan. In that plan, the Board developed GHG emission reduction strategies which
expanded energy efficiency programs, increased utility renewable energy requirements,
developed clean car and Low carbon Fuel Standards (LCFS), developed the cap-and-trade
program and identified adopted discretionary measures to assist the state in meeting the
2020 limits established by AB 32.
In May 2014, the ARB adopted the first update to the original scoping plan which was
necessary to establish long-term GHG policies to make deep GHG emission reductions to
achieve an 80% reduction below 1990 levels by 2050. The update includes key
recommendations for six key economic sectors (energy, transportation, agriculture, water,
waste management, and natural and working lands) as well as short-lived climate
pollutants, green buildings, and the cap-and-Trade Program. The findings largely effect
regulatory measures that will indirectly reduce GHG emissions and generate a need to
update local policies. A summary of the findings for each sector is shown in Tables 3.1a
through 3.le below:

CAPCOA published a white paper, which suggested a screening criterion of 900 metric tons
per year of GHGs and require all projects producing more than 900 metric tons per year of
GHGs produce an inventory of project gases and demonstrate reasonable mitigation
measures necessary to reduce GHG's by 28.3% from business as usual {BAU). BAU is the
projected emissions that would have been otherwise generated without implementation or
consideration of regulatory emissions reductions, design considerations or updated
standards (e.g. 2005 Title 24 standards) or simply put emissions generated prior to the
creation of AB 32. In the absence of formal GHG thresholds, the City of carlsbad uses these
thresholds to determine significance under CEQA.

4.0 METHODOLOGY
4.1 Construction C02e Emissions calculation Methodology
The Project Engineer expects Grading be completed in approximately six weeks, Paving
complete in roughly two weeks and Building Construction complete in just less than six
months. The proposed project would require approximately 4,050 Cubic Yards Cf of
earthwork and would be balanced. Build out of the Project is expected to be late 2015.
Table 4.1 shows the expected timeframes for the construction and project infrastructure
and facilities.

Ldn Consulting, Inc. 10/13/14 1486-02 Buena Vista GHG Study
GHG impacts related to construction will be calculated using the latest URBEMIS2007 air
quality model, which was developed by the California Air Resource Board (CARB).
URBEMIS2007 has been approved by the San Diego Air Pollution Control District (SDAPCD)
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 recommendations from South Coast Air Quality Management
District in 2008 and has been followed within the County of San Diego and Cities within the
County.
4.2 Operational Vehicular Emissions Calculation Methodology
Operational Emissions from daily trips will be quantified utilizing emission levels reported in
grams/mile from the EMFAC2011 emission model for the year 2020. These estimates will
then be tabulated to show the yearly emission levels generated by the project. Utilizing the
347 day correction factor recommended by CARB to account for lower vehicle emissions
over weekends from reduced daily trips. All emission levels will then be multiplied by the
daily mileage and then converted to metric tons for typical reporting consistency. Equation
1 below was utilized to determine GHG levels in Metric tons:
( 9 ) Metric ton GHG(Metric Tons)= Emission Factor -.l-x Annual Mileage x .000001( ) ~e g
4.3 Electricity Usage calculation Methodology
Utilizing methodologies within the California Climate Action Registry General Reporting
Protocol Version 3.1-January 2009 (CCARGRPV3.1) CO2, CH4, and N20 from electricity use
can be calculated utilizing equations III.6b which is shown below:
Equation III.6b (GHG = CO2, or CH4, or N20)
Electricity Use (kWh) x Electricity Emission Factor eb:;~G)
GHG(Metric Tons)= lbs
2•204 metric ton
The electricity emission factors are published within Table C.2 within the CCARGRPV3.1
document and are broken out into sub region. The proposed project is located within
california and for CO2, CH4, and N20 the Electricity Emission Factors are 0.72412,
0.0000302 and 0.0000081, respectively.

Ldn Consulting, Inc. 10/13/14 1486-02 Buena Vista GHG Study
4.4 Natural Gas Usage calculation Methodology
C02e generated from stationary combustion such as water heaters, stoves, and clothing
dryers can be calculated for CO2, CH4, and N20 utilizing equations III.Sb within the
CCARGRPV3.1 document as shown below:
Equation III.Sb (GHG= CO2, or CH4, or N20)
Natrual Gas Emission Factor (';J;/:;J x Fuel Consumed (MMBTu)
GHG(Metric Tons) = k
l,OOO metr! ton
The natural gas emission factors are published within Table C. 7 and C.8 within the
CCARGRPV3.1 natural gas emission factors for CO2, CH4, and N20 are 53.06, 0.005 and
0.0001, respectively. These natural gas emission factors are inserted into equation III.BB
and were published by CCARGRPV3.1. Natural Gas generation rates per residential dwelling
unit were obtained from the 2009 california Residential Appliance Saturation Study (2010)
which was prepared for the california Energy Commission (CEC).
4.5 Solid Waste Emissions calculation Methodology
Solid waste generated from the proposed project will ultimately be discarded as trash and
then deposited into a landfill. The decomposition of organic matter such as food, paper,
yard trimmings and wood are anaerobically digested by bacteria which primarily produces
GHG's as a bi-product. However, organic decomposition occurs at different rates and is a
function of the material content. The Environmental Protection Agency (EPA) published
various emission rates with units of Metric Tons of carbon Dioxide Equivalent per Ton
(Source: Solid Waste management and Greenhouse Gases; A Life-Cycle Assessment of
Emissions and Sinks).
Average waste generation mixes vary between land use however, california's Department of
Resources Recycling and Recovery (calRecycle) estimates that the average waste
generation for single-family could be up to 2.04 tons/unit/year (Source:
http://www.calrecycle.ca.gov/wastechar/WasteGenRates/Residential.htm) and generally
consist of paper plastic and other organics. Table 4.2 on the following page identifies the
typical mix ratio of waste by land use (Source: california 2008 Statewide Waste
Characterization Study -cascadia Consulting Group, 2009). The best way to reduce these
generation rates is to promote recycling.

4.6 Water Use Emission calculation Methodology
Water used from the proposed project will indirectly utilize energy for preparation and
conveyance of clean water to the project site. It is estimated that indirect electricity for
water conveyance requires 12,700 kWh/Million Gallons (MG) (Source:
http://www.greenbuildingadvisor.com/book /export/html/18037). GHG emissions are then
calculated using Equation III.6b as shown in Section 4.3. Water demand per capita is 119
gallons per day for california (Source: Estimated Use of Water in the United States in 2005,
USGS). Given that the US census estimates that there are approximately 2.58 individuals
per household (Source: http://quickfacts.census.gov/qfd/states/OOOOO.html). Therefore, it
is estimated that each unit would require 307 gallons per day or 1,232,605 gallons per year.

5.0 FINDINGS
5.1 Project Related Construction Emissions
Utilizing the URBEMIS 2007 inputs for the model as shown in Table 4.1 above, we find that
grading and construction of the project will produce approximately 168.13 tons over the
construction life of the project. The URBEMIS model outputs are provided as Attachment
A to this report. 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 (Source: SCAQMD 2008). A summary of the construction emissions is shown in
Table 5.1 below.
Table 5.1: Expected Construction Emissions Summary
Year CO2
Construction Total (2014-2015) 168.10
Yearly Average (2020)* 5.60 tons/year over 30 years
Yearly Average Metric Tons (2020)* 5.08 Metric Tons/year over 30 years
Expected Construction emissions are based upon URBEMIS modeling assumptions identified in Chapter 4 of this report.
*Total Construction related CO2 averaged over a 30-year span.
Data is presented in decimal format and may have rounding errors.
5.2 Project Related Operation Vehicular Emissions
Operational emissions will be calculated utilizing a total of 11 single-family units. The
estimated one-way average trip length for home-work trips is 16.8 miles, home-shop trips is
7.1 miles, home-other trips is 7.9 miles. The percentages estimated in the modeling assume
32.9% home-work, 18.0% home-shop, and 49.1 % home-other (URBEMIS). Combined it is
expected that each trip could be 10.68 miles on average.
According to the project traffic study, the project would create approximately 110 daily trips
and with an average trip distance of 10.68 miles, the project would be expected to add
1,174.8 Vehicle Miles Traveled per day or 428,~02 miles per year (based on 347 days to
correct for weekend driving -CARB 2008 In order to obtain a realistic approximation of the
BAU baseline emissions, LDN Consulting ran the EMFAC 2011 model for 2020 which could
be assumed to be BAU and is shown Attachment Bat the end of this report. Utilizing both
emission levels from the EMFAC2011 model and Equation 1 from Section 4.2 of this report
the BAU GHG emission levels was calculated and found to be 200.64 MTC02E.

5.3 Project Related Electricity Use
Based upon the 2009 california Statewide Residential Appliance Saturation Study (2010)
prepared for the CEC the average electricity usage for a dwelling unit per year is 7,605
KWh. Therefore, the 11-dwelling units would be expected to use 83,655 KWh. The
equivalent CO2 emissions are calculated in Table 5.2 below.

5.4 Project Related Natural Gas Usage
Based upon the 2009 california Statewide Residential Appliance Saturation Study (2010)
prepared for the CEC the average natural gas usage for a single-family residential unit
would be 421 Therms or 3,508.33 CF/Unit/Month. Given this the project would require
463,100 CF per ear. Additionally, because lMMBtu is equivalent to 1,000 Cubic Feet of gas
the project would consume 463.1 MMBtu of natural gas per year. The equivalent CO2
emissions are expected to be 24.64 Metric Tons per year as calculated in Table 5.3 below.

5.5 Project Related Solid Waste Emissions Gas Usage
Based upon methods discussed in Section 4. 7 of this report, LDN Consulting multiplied 11
units by the single-family waste generation rate of 2.04 tons/unit/year as reported by
california's Department of Resources Recycling and Recovery (calRecycle), which yields
34.68 tons of trash each year and would typically consist of paper, plastics and other types
of waste (see actual percentages of waste breakdown in Table 4.2 above). Utilizing the
EPA's waste breakdown emission factors per trash type and multiplying those factors with
the projected waste generation yields estimates for equivalent CO2 of 4.59 metric tons for
the 11-unit project, see Table 5.4 below.
