greenhouse gas emissions (GHG); and
WHEREAS, in connection with approval of the CAP, the City Council certified a program
environmental impact report (EIR 13-02) in compliance with the California Environmental Quality Act
(CEQA), which evaluated the potential environmental effects of CAP implementation, including
adoption and enforcement of various ordinances and programs intended to reduce GHG; and
WHEREAS, this ordinance fulfills a CAP requirement to address energy efficiency measures,
photovoltaic systems and alternative water heating systems for new and existing residential and
nonresidential buildings (CAP measures B-1, B-2, D-3, E, F-3, and J-2); and
WHEREAS, the City Planner has determined that: 1) adoption of this ordinance is a subsequent
activity of the CAP for which program EIR 13-02 was prepared; 2) a notice for the activity has been
given, which includes statements that this activity is within the scope of the program approved earlier,
and that program EIR 13-02 adequately describes the activity for the purposes of CEQA Section
15168(c)(2) and (e); 3) the project has no new significant environmental effect not analyzed as
significant in the prior EIR 13-02; and 4) none of the circumstances requiring a subsequent or a
supplemental EIR under CEQA Guidelines Sections 15162 or 15163 exist; and
WHEREAS, California Health and Safety Code section 17958 requires that cities adopt building
regulations that are substantially the same as those adopted by the California Building Standards
Commission and contained in the California Building Standards; and
WHEREAS, the California Green Building Standards Code is a part of the California Building
Standards which contains mandatory green building provisions, as well as a range of voluntary
March 12, 2019 Item #7 Page 3 of 43

that the City may make changes or modifications to the building standards contained in the California
Building Standards based upon express findings that such changes or modifications are reasonably
necessary because of local climatic, geological or topographical conditions; and
WHEREAS, California Green Building Standards Code Section 101.7.1 provides that local
climatic, geological or topographical conditions include environmental conditions established by a city,
county, or city and county; and
WHEREAS, the City Council of the City of Carlsbad finds that each of the amendments, additions
and deletions to the California Green Building Standards Code and California Energy Code contained in
this ordinance are reasonably necessary because of local climatic, geological or topographical
conditions described in Attachment A to this ordinance; and
WHEREAS, Public Resources Code Section 25402.1(h)2 and Section 10-106 of the Building
Energy Efficiency Standards (Standards) establish a process which allows local adoption of energy
standards that are more stringent than the statewide Standards, provided that such local standards are
cost effective and the California Energy Commission finds that the standards will require buildings to
be designed to consume no more energy than permitted by the California Energy Code; and
WHEREAS, the City of Carlsbad has performed cost effectiveness analyses as required by the
California Energy Commission for the local amendments to the California Green Building Standards
Code and California Energy Code contained in this ordinance; and

FINDINGS FOR LOCAL AMENDMENTS TO
2016 CALIFORNIA GREEN BUILDING STANDARDS CODE
2016 CALIFORNIA ENERGY CODE
California Health and Safety Code Section 17958 provides that the city may make changes to the
provisions in the uniform codes that are published in the California Building Standards Code.
Health and Safety Code Sections 17958.5, 17958.7 and 18941.5 require that for each proposed
local change to those provisions in the 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
Standards Code Section 101.7.1 provides that local climatic, geological or topographical conditions
include environmental conditions established by a city, county, or city and county.

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
March 12, 2019 Item #7 Page 15 of 43
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 °Fin 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 res_idential
and nonresidential buildings will significantly reduce emissions from these uses.
