It still has to go to Law & Legislation. Below are the staff report, executive summary and full report as presented to the Planning Commission:

It's fairly comprehensive, the changes aren't just to the CBD but citywide, with several new categories based on parts of town--CBD is basically I to Q Street east to 16th, "urban" is along business corridors like J Street, Folsom Blvd, Stockton Blvd, Broadway and north along I-5, "traditional" in older neighborhoods like Midtown, East Sacramento and Land Park, and "suburban" for postwar auto suburb neighborhoods like the Pocket and Natomas.
And yeah, I'm hoping that the surplus of office space, combined with some opportunities to convert some commercial buildings to residential (with no parking requirements) in the new parking code, will encourage some developers to do more residential infill in former office properties downtown. Los Angeles introduced a similar ordinance in 2000 and tripled the population of their downtown by turning mostly-vacant office buildings into condos.
