5.21 Climate Change

Changes in Growing Season and Species Distribution: Changes in growing season
conditions could cause variations in crop quality and yield. Plant and wildlife
distributions may also be affected by changes in temperature, competition from
colonizing species, regional hydrology, sea level, and other climate-related effects.
Rising Sea Levels: Sea levels are expected to steadily rise by mid-century, which
could inundate portions of the coastline.

5.21.4 PROJECT DESIGN FEATURES

Green Development Program

The Project would implement a Green Development Program, included as Appendix 1-B to
the Centennial Specific Plan. The Green Development Program includes but is not limited to:

• Project features that comply with and implement the CCAP and

• Additional Project features that comply with and implement State and federal GHG
reduction mandates and goals.

The Project first applies land use planning principles to create a balanced master-planned
community that includes mixed-use neighborhoods where residential, commercial, and
other employment-generating uses and institutional/public uses are proximate to each
other and connected by a network of pathways to reduce reliance on automobile use and
off-site commuting. The bicycle and pedestrian trail system connects community uses such
as neighborhood parks, elementary schools, and neighborhood-scale retail to reduce single-
occupancy automobile travel for these neighborhood-scale destinations.

The Project then applies infrastructure and building design standards to reduce GHG
emissions through energy and water conservation measures. The Project’s integrated water
resources management approach would (1) minimize water use and maximize water reuse
through development of two wastewater reclamation facilities (WRF) that will produce
recycled water for landscape irrigation use throughout the Project site and (2) incorporate
a variety of water supply sources including State Water Project (SWP) water, banked water,
groundwater, and other non-SWP supplies to reduce the GHG emissions associated with
water supply delivery.

The Project includes components (e.g., the Mobility Plan, Green Development Program) to
conserve and enhance open space, promote transit, and reduce waste. Development within
established Significant Ecological Areas would be entirely avoided, thereby minimizing
disturbance of high-value biological resources and preserving open space areas that
sequester CO2. As part of the Green Program the Project incorporates a comprehensive waste
diversion and recycling program. In order to promote the use of alternative forms of
transportation, the Project includes a Transportation Management Association (TMA) that
develops strategic linkages with other Antelope Valley/Santa Clarita Valley TMAs or similar
organizations in order to maximize transit efficiencies and services. The TMA’s purpose is to
coordinate and facilitate transit and rideshare usage to serve as many riders as possible
thereby reducing GHG emissions from mobile sources.
