Baseline

• Salient Characteristics– Refinement of past work (2nd revision)– Includes the addition of approximately

one million more people by 2020– Snapshot of the future based on state

and regional plans– Based on trends of the past 20-30 years

Depicts how the region is likely to develop based on

recent plans


November 15, 1999

Strategy

• Salient Characteristics– Includes addition of approximately one million more people– Depicts impacts of voluntary, interjurisdictional

cooperation– Reflects market-based housing mix– Requires additional water conservation and telework– Consistent with previously expected population and

employment trends at the county-level– Requires incremental changes from current development

patterns

Depicts how the region is likely to develop based on adherence to Envision

Utah’s goals and strategies


November 15, 1999

The pursuit of this strategy is motivated by the common and regional nature of many of our challenges. We share the same roads, airshed, water resources, and natural assets. We have an enviable quality of life, but we have major challenges.
