• All things on earth are connected,
• each a part of the web of life.
• What we do, as human beings
• and designers, affects
• each strand in the web.
• ...and water is the source of life.

Guiding Principles

• Make plans that inspire and excite people
• Continually consider the property as a single
  site
• Master plan as a living document
• Incorporate flexible transportation systems
• Incorporate pedestrian friendly design
• Incorporate sustainability principles
• Adopt metrics that track the OCGP communitys
  progress in implementing the sustainability
  vision
• Promote energy efficiency throughout the parks
  infrastructure
• Create alternatives to private vehicles
• Minimize light pollution maximize energy
  efficiency
• Establish a connection between park habitats
  regional ecosystems
• Prescribe operational principles that minimize
  overhead costs financial risk
• Minimize demand for resources maximize the
  opportunities for on-site supply of resources
• Create a sense of place

Great ParkSustainability Highlights
15
Great Park / Heritage FieldsCommitment to
Sustainability, LEED, and LID Design

• Air Quality Conservation
• An INTRA Great Park community transit system
  serving Heritage Fields communities and the
  Great Park
• Biological Resource Conservation/Biodiversity
• Golf course facilities designed to form an
  enhanced open space connection between the Great
  Park and the Wildlife Refuge
• Energy Conservation
• All buildings within the private sector areas of
  the Great Park communities to be LEED certifiable
  (commercial buildings) or conform to the City of
  Irvine Green Building standards
• Agriculture
• Permanent agricultural lands relocated adjacent
  to the Great Park to create/expand an
  agricultural Heritage Park component

16
Great Park / Heritage FieldsCommitment to
Sustainability, LEED, and LID Design

• Solid Waste Reduction
• A recycling facility on land interests acquired
  from the County within the Great Park community
  to keep all green waste and construction waste
  onsite
• Transportation
• Right-of-way reservation for elevated
  people-mover connecting the Irvine Transit Center
  to the Great Park
• Entry roads to the Great Park to be Green
  Streets
• Water Quality
• A water treatment/recycling facility
  within/adjacent to the Wildlife Corridor or
  Riparian Corridor

17
Infrastructure Goals

• To create streets that are public places to be
  enjoyed by all and that are environmentally
  sustainable.
• To provide
• Cleaner water and air
• Higher biological value
• Lower energy use
• Resilience in the design of streets
