Placentia Council/Manager Relationship

What is a City Manager? Imagine your city government as a football team, with skilled players and keen instincts, ready to lead a drive to the goal line. On the field is the City Council, acting in every way as the city’s coaching staff. The Council scopes out the challenges ahead, devises the plays, and prepares the team for success, but no matter how exciting the plans are, they can’t be implemented without the quarterback.

City Managers are like that quarterback. They relay the plans from the coach to the team, and organize the city employees to move the ball down the field for a touchdown. They are the vital connection between planning and execution that every city depends on. City Managers oversee the operations and finances of cities to make sure the City Council’s policy direction becomes a reality.
