Geraldine Knatz, executive director of the Port of Los Angeles, is retiring at the end of the year. Knatz is the first department head to announce she is leaving during Los Angeles Mayor Eric Garcetti’s assessment of department heads and general managers. Knatz’s departure from her post occurs amidst a $5-billion expansion of the Panama Canal, which threatens the Los Angeles-Long Beach harbor complex. She was appointed by former Los Angeles Mayor Antonio Villaraigosa. Gary Lee Moore, city engineer and general manager of the Bureau of Engineering, will serve in Knatz’s position until a permanent replacement is found. In related news, Gina Marie Lindsay will remain as the executive director of Los Angeles World Airports amidst a flurry of personnel changes.
