Yesterday I helped make signs at the Tenderloin Neighborhood Development Corporation:  “Rise up for working elevators.”  An activist resident of the Tenderloin, Luis Castillo, pictured here,  discovered how unfriendly Hallidie Plaza is to people in wheelchairs, parents with strollers, and tourists with more luggage than can be accommodated on escalators, and no one wanted to take responsibility for the out-of-order elevator there, so Senior and Disability Action will have a protest there.  Mayor Breed wants to revive this plaza, but an elevator that’s been broken for years is not a sign of progress.  I suspect there is fear that a working elevator would be used as sleeping quarters.    But haven’t Mayor Breed and Supervisor Peskin just worked together to lower the required percentage of affordable housing units?  How do we rise above that?
