Plan Bay Area 2050 Scenarios

S21: Blueprint Basic

  • This is the "base" scenario in the sense that we are doing it first and the others build off of it
  • Uses s21 control total files
  • Uses Blueprint Basic logsums
  • Uses s21 zoning modifications: major upzoning in all growth geogs
  • Has almost all strategies in

s20: Baseline for PBA50

  • This is the "baseline" scenario in the sense that it doesn't have any pba50 changes and so it also has far lower control totals
  • Uses s20 control total files (these are minus the additional units built bc of housing policy in pba50)
  • Uses Baseline logsums (somewhat less congestion than others?)
  • Uses s20 zoning modifications: these are minimal in that the do typical No Project treatment (UGB, upzoning within) but may also need UGB expansion to fit control totals
  • Has no new strategies from PBA50

s22: Blueprint Plus Fix It First

  • This is the higher funding scenario
  • Uses s22 control total files
  • Uses Blueprint Plus Fix It First logsums (very similar to s21 logsums)
  • Uses s22 zoning modifications: same as s21
  • Adds/modifies these strategies (working off of s210:
    1. adds incubator strategy
    2. increases size of affordable housing fund
    3. more slr protection

s23: Blueprint Plus Crossing

  • This is the higher funding scenario plus the New Transbay Crossing
  • Uses s23 control total files
  • Uses Blueprint Plus Crossing logsums (moderately different from other scenarios)
  • Uses s23 zoning modifications: slightly higher upzoning than s21 and s22 at a few new/upgraded stations
  • Same strategies as s22

s24: Final Blueprint

  • Builds off of s23
  • Includes both error correction and policy modifications
