Compass Blueprint:  Compass Blueprint is a new way to look at how we grow. The Compass Blueprint Growth Vision is a response, supported by a regional consensus, to the land use and transportation challenges facing Southern California now and in the coming years.The Growth Vision is driven by four key principles:

  • Mobility – Getting where we want to go
  • Livability – Creating positive communities
  • Prosperity – Long-term health for the region
  • Sustainability – Promoting efficient use of natural resources

To realize these principles on the ground, the Growth Vision encourages:

  • Focusing growth in existing and emerging centers and along major transportation corridors
  • Creating significant areas of mixed-use development and walkable communities
  • Targeting growth around existing and planned transit stations
  • Preserving existing open space and stable residential areas

They are intended to provide new housing opportunities that will also provide increased demand for retail in more concentrated, strategic locations (e.g., at major intersections).

Global Gateway:  Ontario is increasingly identified for the competitive advantages it provides to businesses that want to succeed in the global marketplace and for its growing importance to the state, national and international economies. Ontario’s distinction as a Global Gateway is due to its strategic Southern California location at the center of a rapidly developing freight movement system that includes LA-Ontario International Airport (ONT), two railroads, four major freeways and an expanding network of freight forwarders. ONT is one of the fastest growing and ambitious cargo airports outside the booming Asia-Pacific market and home to United Parcel Services Western Regional Hub providing daily direct flights to China.

Public (Noun):  Residents, business, visitors and travelers.
Rare or Endangered Species:Rare:  A native California plant (species, subspecies or variety) is rare when, although not presently threatened with extinction, it is in such small numbers throughout its range that it may become endangered if its present environment worsens (Section1901, Fish and Game Code). Since 1985, this designation applies to plants only.Endangered:  A native California bird, mammal, fish, amphibian, reptile, or plant (species, subspecies or variety) is endangered when it is in serious danger of becoming extinct throughout all, or a significant portion of its range due to one or more causes, including loss of habitat, change of habitat, over-exploitation, predation, competition or disease (Section 2062, Fish and Game Code).
Recycled Water: Recycled Water is former wastewater (sewage) that has been treated to remove solids and certain impurities, and then allowed to recharge the aquifer or used for non-potable purposes rather than being discharged to surface water.

SANBAG:  San Bernardino County Association of Governments.
SCAG:  Southern California Association of Governments.
Sensitive Land Uses:  Uses that by their nature and characteristics can be significantly impacted by the noise, odor, vibration, air quality and inherent hazards associated with other uses near it.  Sensitive uses include, but are not limited:  single family residences, schools, churches, hospitals, day care facilities and nursing homes. 
Sensitive Species:  Sensitive” refers to naturally-reproducing fish and wildlife species, subspecies, or populations which are facing one or more threats to their populations and/or habitats.

Sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs.
Urban Run-off:  Urban runoff is surface runoff of rainwater over impervious surfaces.  During rain storms and other precipitation events (including run-off from overwatering landscape areas), these surfaces (built from materials such as asphalt, cement, and concrete), along with rooftops, carry polluted stormwater to storm drains, instead of allowing the water to percolate through soil. This causes lowering of the water table (because groundwater recharge is lessened) and flooding since the amount of water that remains on the surface is greater.
Waste Diversion:  The act of preventing garbage from being disposed of in landfills or incinerators by reducing the amount of materials that you use or buy, reusing products, recycling or composting.
Wastewater  Spent or used water with dissolved or suspended solids, discharged from homes, commercial establishments, farms, and industries.
Williamson Act :  Known formally as the California Land Conservation Act of 1965, it was designed as an incentive to retain prime agricultural land and open-space in agricultural use, thereby slowing its conversion to urban and suburban development.  The program entails a ten-year contract between the City or County and an owner of land whereby the land is taxed on the basis of its agricultural use rather than its market value. The land becomes subject to certain enforceable restrictions, and certain conditions need to be met prior to approval of an agreement.
