This week is a major opportunity to speak up about the SFPD’s traffic safety practices. The Police Commission and a Board of Supervisors committee will hold a hearing on how police investigate traffic collisions involving people walking and biking. Elsewhere, SPUR discusses the reform of CEQA and the first public meeting on the Irving Commons project will be held.

Here are all of this week’s calendar highlights:

• Tuesday: On the Pedestrian Safety Advisory Committee’s agenda is a presentation from the SF Fire Department on its recent opposition to bulb-outs and narrower streets. You’re invited to share your thoughts with SFFD and the committee. 6 p.m.

• Thursday: At a SPUR lunchtime forum, city planners and sustainable planning advocates will discuss how the Sacramento Kings’ new basketball arena gave a political push that brought partial reform to the CA Environmental Quality Act, eliminating the requirement for developments in urban areas to be analyzed according to the car-centric transportation planning metric Level of Service. 12:30 p.m.

• Also Thursday: At a joint hearing, the Board of Supervisors’ Neighborhood Services and Safety Committee and the Police Commission will review how SFPD investigates crashes involving people walking and biking. The hearing follows a recent spate of pedestrian crashes and repeated instances of SFPD blaming victims of traffic violence for getting hurt. Dozens of residents shared stories of anti-bike hostility from the police at an October hearing. 5 p.m.

• More Thursday: Organizers of the Irving Commons Project will hold a neighborhood meeting in the Inner Sunset to field input on the proposed study for a plaza on Irving Street between Ninth and 10th Avenues. 6:30 p.m.
