Introduce an Energy Conservation Ordinance and Electric Vehicle Charging
infrastructure Ordinance.
Climate Action Plan Ordinances
MCA 17-0002 {PUB17Y-0013)
Recommended Action
Introduce ordinances amending Carlsbad Municipal Code, Title 18, Chapters 18.21 and 18.30
regarding energy efficiency, renewable energy, alternative water heating and electric vehicle
charging infrastructure for residential and nonresidential new construction and major
renovations.
Executive Summary
The city's Climate Action Plan (CAP) was adopted by the City Council on September 22, 2015.
The CAP calls for the adoption of ordinances related to energy efficiency, renewable energy,
alternative water heating and electric vehicle charging infrastructure. Implementation of these
ordinances is intended to reduce greenhouse gas (GHG) emissions and assist in reaching the
GHG reduction targets contained in the CAP. These ordinances amend Title 18 of the Carlsbad
Municipal Code, and therefore require City Council approval. The energy-related ordinances
also constitute amendments to the California Building Code Title 24, Parts 6 and 11, and must
receive approval from the California Energy Commission {CEC) and be filed with the California
Building Standards Commission (CBSC) prior to implementation. The electric vehicle charging
ordinance amends the California Building Code Title 24, Part 11 (CALGreen) and will become
effective 30 days after City Council adoption and after filing with the CBSC.
Discussion
The city's Climate Action Plan (CAP), adopted by the City Council on September 22, 2015, calls
for the adoption of ordinances related to energy efficiency, renewable energy, alternative
water heating and electric vehicle charging infrastructure. Implementation of these ordinances
is intended to reduce greenhouse gas (GHG) emissions and assist in reaching GHG reduction
targets contained in the CAP .
Generally, the ordinances are designed to reduce energy consumption, increase local
production of renewable energy, reduce natural gas usage for water heating and reduce GHG
February 26, 2019 Item #3 Page 1 of 74
emissions from vehicles. The purpose, general requirements and applicability of each ordinance
is described below. A summary of the specific ordinance requirements is contained in Exhibit 4.
Energy Conservation Ordinances
Energy Efficiency-the purpose of the energy efficiency provisions is to increase the energy
efficiency of residential and nonresidential buildings. This is accomplished through inclusion of
cost-effective energy efficiency measures in new construction and/or major renovations.
Residential efficiency provisions apply to renovations of existing single-family and multi-family
residential buildings with a building permit valuation of $60,000 or more. This is the same
threshold that triggers a local Coastal Development Permit. Building permit applicants can opt
to perform a home energy assessment and be exempted from the ordinance requirements if
they achieve a minimum energy efficiency score.
Nonresidential efficiency provisions apply to all new construction and major renovations adding
more than 1,000 square feet of floor area or with a building permit valuation of $200,000 or
more.
Photovoltaic {PV} Energy-the purpose of the PV provisions is to increase the amount of locally
generated renewable energy in nonresidential buildings. This is accomplished through the
inclusion of cost-effective PV systems in new construction and major renovations.
The PV provisions apply to all new nonresidential construction and major renovations with a
building permit valuation of $1,000,000 or more that affect 75 percent or more of the existing
floor area. It also applies to projects increasing the existing roof area by 2,000 or more square
feet.
Water Heating-the purpose of the water heating provisions is to reduce the usage of natural
gas for heating water in residential and nonresidential buildings. This is accomplished through
the inclusion of cost-effective energy-efficient electric water heaters and/or solar water heating
systems in all new residential and nonresidential construction. A separate residential water
heating ordinance is proposed because its provisions rely on the 2019 Energy Code update,
which will become effective on January 1, 2020. As such, the local ordinance amending
residential water heating requirements will not become effective until January 1, 2020.
Electric Vehicle (EV) Ordinance -the purpose of the electric vehicle ordinance is to promote
increased EV use by providing more opportunity for EV charging. This is accomplished through
the inclusion of cost-effective EV charging infrastructure in new construction and major
renovations.
The ordinance applies to all new residential and nonresidential construction. The ordinance also
applies to major residential renovations, which are defined as: 1) one and two-family dwellings
and townhouses with an attached garage, whose project includes an electrical service panel
upgrade, or has a building permit valuation of $60,000 or more; and 2) a multifamily project
February 26, 2019 Item #3 Page 2 of 74
(three or more dwellings) undergoing replacement/upgrade of major building systems, which
includes 2,500 square feet or more of site work (grading, parking area replacement/addition, or
landscaping), and has a building permit valuation of $200,000 or more.
Cost-effectiveness
Public Resources Code Section 2502.l(h)2 requires that local jurisdictions perform and submit
to the CEC a "cost effectiveness" study with supporting analysis showing that ordinances with
additional energy saving measures are cost-effective. City staff partnered with the California
Energy Codes and Standards team, as well as the Center for Sustainable Energy (CSE) and TRC
Solutions, to prepare cost-effectiveness studies for the proposed energy conservation
ordinance. All studies followed CEC analysis protocol and showed that the energy saving
measures in the proposed ordinance are cost-effective based upon utility bill savings by the
customer.
The city also worked with CSE and TRC to prepare a cost-effectiveness study for the EV
ordinance, even though this is not required by state law. All studies are on file with the City
Clerk's Office and available for public review.
Fiscal Analysis
Cost associated with administering these ordinances will be recovered through plan check, permitting
and inspection fees currently in effect. No fee modifications are proposed.
Next Steps
Upon adoption, the energy conservation ordinance (energy efficiency, PV, and water heating)
will be submitted to the CEC for review and approval. The ordinance will become effective
upon CEC approval and after filing with the CBSC. The residential water heating provisions will
become effective on January 1, 2020, concurrent with the statewide 2019 Building Standards
Code update. The EV ordinance will become effective 30 days after City Council adoption and
filing with the CBSC.
Environmental Evaluation (CEQA)
The project was previously evaluated in the Final Program Environmental Impact Report (EIR)
for the General Plan update (GPA 07-02), Climate Action Plan (SS 15-05) and other documents
(EIR 13-02), dated September 22, 2015. The EIR evaluated the potential environmental effects
of the implementation of the Climate Action Plan including the adoption and enforcement of
energy conservation and electric vehicle charging infrastructure ordinances. This project is
within the scope of the Final Program EIR 13-02 and no further California Environmental Quality
Act (CEQA) compliance is required.
Public Notification
The city conducted a variety of public outreach efforts for the CAP ordinances, including:
individual and group stakeholder meetings; presentations at the Carlsbad Chamber of
Commerce, Carlsbad Sustainability Coalition and Building Industry Association (BIA); press
releases and a news article in Carlsbad Business Journal; and distribution of fact sheets through
emails to interested parties and displays at the Development Services front counter. The draft
ordinances were posted on the city's website for public review and comment.

Key to Justification for Amendments to Title 24 of the California Code of Regulations
C This amendment is justified on the basis of a local climatic condition. Carlsbad has many
brush-covered hillsides and protected natural open space areas adjacent to developed areas.
Though relatively moderate compared to inland portions of the region, the seasonal climatic
conditions during the late summer and fall in Carlsbad are characterized by frequent Santa
Ana weather patterns. Santa Ana conditions are dry, hot, strong and gusty winds that produce
February 26, 2019 Item #3 Page 17 of 74
Attachment "A" to Ordinance No. CS-347
extreme dryness and some of the highest winds in San Diego County, have fanned the region's
most catastrophic wildfires and can impact public health in the populated coastal zone by the
extreme heat and occasional smoke.1
Carlsbad has experienced larger increases in annual temperature than other parts of the state.
Compared to the first six decades of the 20th century, annual temperatures have increased by
more than 1 °F in many parts of the state, with some areas (including the San Diego region)
exceeding 2°F.2 This heating is expected to continue well into the future, with estimates
ranging between 4-6°F and 7-9°F by the end of the century.3
T This amendment is justified on the basis of a local topographical condition. Carlsbad has six
and a half miles of beaches, three lagoons, several creeks and other low-lying areas prone to
flooding. The San Diego Multi-jurisdictional Hazard Mitigation Plan ranks coastal storm,
erosion and flooding among the top five hazards for Carlsbad, with potential property loss
exposure approaching $200 million dollars.4 There is broad scientific consensus that the earth
will continue to warm and that sea levels will rise as a result of thermal expansion of the
oceans and increased contributions from melting glaciers. By the end of the century, sea level
could rise by 1.7 to 6.6 feet, inundating beaches and impacting miles of roads and public
accesses, the state campgrounds, hundreds of properties, and more than 1,000 acres of
environmentally sensitive lands in Carlsbad.5
E This amendment is justified on the basis of local environmental conditions. Sustainability is a
core value of the Community Vision, and an intrinsic part of the Carlsbad General Plan. Energy
efficiency enhances the public health and welfare by promoting the environmental and
economic health of the city through incorporating green practices into the design,
construction, maintenance and operation of new and existing buildings. Installation of
renewable energy systems to provide a building's energy and water heating needs enhances the
public health and welfare by reducing air pollution and greenhouse gas (GHG) emissions that
come from fossil fuel combustion.
The amendments to the California Green Building Standards Code and Energy Code are
reasonably necessary to achieve the following goals of the General Plan Sustainability
Element and Carlsbad Climate Action Plan:
• Promote energy efficiency and conservation in the community;
• Pursue the use of sustainable energy sources;
• Reduce the community's greenhouse gas emissions and foster green development
patterns;
• Maintain a long-term balance among environmental, social and economic concerns, to

ensure a vibrant, healthy and prosperous community.
The above-listed conditions within the city pose local hazards for which amendments to the California
Green Building Standards Code and California Energy Code are required. Human activities that release
heat-trapping greenhouse gases into the atmosphere (such as through fossil fuel combustion) are the
primary driver of climate change.6 Failure to address and significantly reduce GHG emissions could
result in increased extreme heat events, dry weather conditions and risk of wildfire. Rises in sea level,
including in the city's lagoons, could put at risk Carlsbad homes and businesses, public facilities,
pub Ii c roads (especially Carlsbad Boulevard) and accessways.
According to the Carlsbad Climate Action Plan, community-wide GHG emissions need to be reduced
49 percent by 2035 to help achieve statewide reduction targets necessary to reduce impacts from
climate change. Residential land uses account for 25 percent of the community's GHG emissions,
while commercial and industrial uses are responsible for about 32 percent. Implementation of energy
efficiency, photovoltaic energy and alternative water heating systems in new and existing residential
and nonresidential buildings will significantly reduce emissions from these uses.

uniform codes and published in the California Building Standards Code which regulate
buildings used for human habitation, the city council must make findings supporting its
determination that each such local change is reasonably necessary because of local
climatic, geological, or topographical conditions. Furthermore, California Green Building

Key to Justification for Amendments to Title 24 of the California Code ofRegulations
C This amendment is justified on the basis of a local climatic condition. Carlsbad has
many brush-covered hillsides and protected natural open space areas adjacent to
developed areas. Though relatively moderate compared to inland portions of the
region, the seasonal climatic conditions during the late summer and fall in
Carlsbad are characterized by frequent Santa Ana weather patterns. Santa Ana
conditions are dry, hot, strong and gusty winds that produce extreme dryness and
some ofthe highest winds in San Diego County, have fanned the region's most
catastrophic wildfires and can impact public health in the populated coastal zone
by the extreme heat and occasional smoke.1
Carlsbad has experienced larger increases in annual temperature than other parts
of the state. Compared to the first six decades of the 20th century, annual

Assessment, p.27. February 26, 2019 Item #3 Page 41 of 74
Attachment "A" to Ordinance No. CS-349
temperatures have increased by more than 1 °F in many parts of the state, with
some areas (including the San Diego region) exceeding 2°F.2 This heating is
expected to continue well into the future, with estimates ranging between 4-6°F
and 7-9°F by the end of the century.3
T This amendment is justified on the basis of a local topographical condition.
Carlsbad has six and a half miles of beaches, three lagoons, several creeks and
other low-lying areas prone to flooding. The San Diego Multi-jurisdictional Hazard
Mitigation Plan ranks coastal storm, erosion and flooding among the top five
hazards for Carlsbad, with potential property loss exposure approaching $200
million dollars.4 There is broad scientific consensus that the earth will continue to
warm and that sea levels will rise as a result of thermal expansion of the oceans
and increased contributions from melting glaciers. By the end of the century, sea
level could rise by 1.7 to 6.6 feet, inundating beaches and impacting miles of roads
and public accesses, the state campgrounds, hundreds of properties, and more
than 1,000 acres of environmentally sensitive lands in Carlsbad.5
E This amendment is justified on the basis of local environmental conditions.
Sustainability is a core value of the Community Vision, and an intrinsic part of the
Carlsbad General Plan. Energy efficiency enhances the public health and welfare
by promoting the environmental and economic health of the city through
incorporating green practices into the design, construction, maintenance and
operation of new and existing buildings. Providing charging infrastructure for
electric vehicles will reduce air pollution and GHG emissions by facilitating increased
use of zero emission vehicles.
The amendments to the California Green Building Standards Code are reasonably
necessary to achieve the following goals of the General Plan Sustainability
Element and Carlsbad Climate Action Plan:
• Promote energy efficiency and conservation in the community;
• Pursue the use of sustainable energy sources;
• Reduce the community's greenhouse gas emissions and foster green
development patterns;
• Maintain a long-term balance among environmental, social and economic
concerns, to ensure a vibrant, healthy and prosperous community.
The above-listed conditions within the city pose local hazards for which amendments to
the California Green Building Standards Code are required. Human activities that release
heat-trapping greenhouse gases into the atmosphere (such as through fossil fuel
combustion) are the primary driver of climate change.6 Failure to address and

significantly reduce GHG emissions could result in increased extreme heat events, dry
weather conditions and risk of wildfire. Rises in sea level, including in the city's lagoons,
could put at risk Carlsbad homes and businesses, public facilities, pub Ii c roads
(especially Carlsbad Boulevard) and accessways.
According to the Carlsbad Climate Action Plan, community-wide GHG emissions need to
be reduced 49 percent by 2035 to help achieve statewide reduction targets necessary to
reduce impacts from climate change. Cars and light trucks account for 39 percent of
Carlsbad's GHG emissions. Providing electric vehicle charging infrastructure will facilitate
increased use of plug-in hybrid and battery electric vehicles, thereby reducing GHG
emissions from this sector. For example, the California Air Resources Board estimates that
each installed electric vehicle charging station could reduce GHG emissions by 8 to 17
metric tons (CO2 equivalent gases) per year.7

Council Memorandum

From: ff9J Gary T. Barberio, Assistant City Manager ~
Via: Scott Chadwick, City Manager

Carlsbad
Re: Responses to Questions from February 25 City Council Briefings
Agenda Item No. 2 -Agreements with Northstar Utilities Solutions and Invoice Cloud for Utility
Billing System Upgrade and Payment Services
Question 1: Per our CMC, why was this not pursued through a RFP process?
Answer: An RFP process was not used as the city is upgrading software it already has a license
for from the company that created the software. The software upgrade can only be obtained
from the company that created the software. During the contract process, city IT staff
investigated whether the upgrade could be obtained from any other source and was unable to
find any other vendors. Therefore, the city IT Department is bringing forward the contracts for
City Council consideration pursuant to CMC 3.28.060(A)(2), as there is only one firm that can
reasonably provide the services. ·
Agenda Item No. 3 -Energy Conservation and Electric Vehicle Charging Infrastructure
Ordinances
Question 1: Please provide the link to the costing and technical studies referenced.
Answer: http://carlsbadca.gov/services/depts/pw/environment/cap/ordinances.asp
Question 2: What outreach specifically to residents was conducted?
Answer: Two of the proposed CAP ordinances affect residents directly, the energy efficiency
and EV charging ordinances. Based on past permit data, the number of projects that would
meet the threshold in a typical year is between 30 and 50. Since it was not possible.to identify
those residents potentially considering major remodels in the future, the project team
prepared informational materials about the proposed ordinances and made them available on
the city website, at the Faraday Center building counter, the City Clerk's Office and Dove
Library. In addition, the project team reached out to the architects, builders and contractors
who have worked with residents on projects of this size in recent years and who generally do
business in Carlsbad.
