After a long career with Metro, the agency’s chief planning officer Carol Inge announced this week that she will be retiring at the end of the year.

Carol is certainly leaving on a high note: last week the Metro Board unanimously adopted a $300-billion long-range plan that was assembled by the planning department. The plan is intended to guide the agency for the next three decades. It will also double the number of miles of Metro rail, includes the county’s first congestion pricing program and targets freeway improvements that will hopefully clear up some key bottlenecks.

Carol, who is 55, worked in planning and redevelopment for the cities of Inglewood and Huntington Beach before joining the Southern California Rapid Transit District in the late 1990s. She was a transportation planning manager with the Los Angeles County Transportation Commission, which evolved into Metro.
