The commission meeting begins at 6:30 p.m. in the community hall of the library, located at 3491 Mt. Diablo Blvd.
On the agenda is a continued public hearing on The Terraces project at the corner of Deer Hill Road and Pleasant Hill Road.
According to the city manager's Friday report, the developer has scaled back the project from 315 to 208 apartments. The new plan also reduces the number of parking space from 569 to 375.
At a hearing in early October, more than 100 people attended, many of them criticizing the size and scope of the development.
Meanwhile, the council will be meeting at the Art & Science Discovery Center in the library about the same time.
On their agenda is a public hearing on a proposed ordinance to prohibit smoking in more areas of the city, including multi-family housing projects, outdoor public areas, public events and outdoor dining areas.
City staff states in a report to the council that the new restrictions are needed to protect the public's health, safety and welfare due to the dangers of second-hand smoke.
