5.21 Climate Change

Title 24 Green Building Standards Code. The 2013 California Green Building Standards
Code (24 CCR Par 11), also known as the CALGreen Code, contains mandatory requirements
aimed to reduce construction waste; make buildings more efficient in the use of materials
and energy; and reduce environmental impact during and after construction. For example,
projects must recycle and/or salvage for reuse a minimum of 50 percent of nonhazardous
construction and demolition debris or meet local ordinance, whichever is more stringent
(Section 5.408.3). In addition, 100 percent of trees, stumps, rocks and associated vegetation
and soils resulting primarily from land clearing shall be reused or recycled (Section 5.408.4).

Los Angeles Green Building Standards Code. Title 31 of the Los Angeles County Code of
Ordinances was adopting in 2013 in response to the mandates set forth in the CALGreen
Code. The purpose of Title 31 is to improve public health, safety, and general welfare by
enhancing the design and construction of buildings through the use of building concepts
having a reduced negative impact, or positive environmental impact, and encouraging
sustainable construction practices in planning and design; energy efficiency; water efficiency
and conservation; material conservation and resource efficiency; and environmental air
quality.

Antelope Valley Area Plan (AVAP). Policy COS 17.1 promotes green building techniques
for the construction and operation of public and private buildings in the unincorporated
Antelope Valley. Policy COS 17.9 requires reduction, reuse, and recycling of construction and
demolition debris.

Project Design Features

PDF 17-2. PDF 17-2 of Section 5.17, Other Services, states that the Project has committed to
diverting from landfill disposal 100 percent of soil during grading activities, and at least 70
percent of nonhazardous construction and demolition waste, which exceeds the 65 percent
diversion requirement with the Tier I voluntary measure in Section A5.408.3.1 of the
California Green Building Standards Code. This goal also exceeds the 50 percent reduction
required by Section 20.87.040 of the County Code and Sections 4.408.5/5.408.1.4 of the
CALGreen Code. PDF 17-2 is required for implementation through MM 17-9.

PDF 21-21. The Green Development Program requires that, prior to the issuance of each
construction permit, the Project Applicant/Developer shall require in contract
specifications, that contractors set goals to limit unnecessary construction equipment idling
to three minutes and include a program to encourage equipment operators to achieve the
three-minute goal.

As the Project will incorporate these project design features and must comply with these
applicable regulations imposed by law, the Project would contribute to the achievement for
AB 32’s goals related to construction emissions.

PDF 21-21 is required for implementation through MM 21-4.
