Scenarios for 2050 using UPlan Model

Base Case Scenario — Detail

Click for larger version

This is a view of the Sacramento watershed area in the year 2050, showing where development will occur if no changes in planning or development are made. It is used to compare with the other scenarios, which take into account possible effects from natural disasters or limited natural resources.

The current population and population projections are taken from the Department of Finance, 2007[*]. The persons per household figures are derived from the Census 2000 Summary File 1, State and County Summary table, as an average of owner-occupied and renter-occupied numbers. Employees per household numbers are taken from the Department of Finance 2006 county profiles.

* There are 2 cases where we did not use the DOF population projections: Sierra county, which predicts a decrease in the number of people who will live there in 2050 from the year 2000 (we added 20% to the 2007 number to get to our 2050 number) and Alpine county. The DOF population for Alpine does not factor in development from vacation homes and ski resorts; however, Alpine county planners did establish an estimated "full occupancy" 2050 population based on full build out of existing specific plans and logical growth within the other settled areas.
