PBA50scenarios

Plan Bay Area 2050 Scenarios

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

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

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

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
