  • Why do we model?1. They allow us to test a wide variety of policy, planning and investment alternatives

    2. They create a consistent set of rules and criteria to test the alternatives.

    3. They respond to a wide variety of statutes requiring more accurate forecasts than in the past.

  • What do we get from our models?Spatial OutputWhere is the growth?Tabular OutputHow much?AnalysisWhat are the likely impacts?

  • UPlanSimpleRelatively simple dataGenerally accessible demographic inputsSimple algorithm/rulesRule basedThe rules govern the systemUrban GrowthA simple inexpensive model with rapid run times and fast data development

  • Land UsesCustomizableAs of UPlan 2.6xAggregate3400+ Land uses across 536 city and county general plansDeveloped Land Use TypesNot Agriculture or TimberResidential TypesDensity ClassesEmployment TypesSquare Feet per EmployeeFloor Area Ratio

  • Residential DemographicsPopulation GrowthStarting populationEnding populationAverage Household Size (PPHH)Housing Proportions by Density ClassPercentage of new units entering each residential typeAverage gross footprint per household

  • Employment DemographicsAverage number of employed people per householdPercentage of employees entering each employment typeAverage square footage per employee in buildings for each employment typeFloor Area Ratio for each employment type
