president washington dismissed l'enfant in march 1792, due to his insistence on micromanaging the city's planning, which had resulted in conflicts with the three commissioners appointed by washington to supervise the capital's construction. andrew ellicott, who had worked with l'enfant surveying the city, was then commissioned to complete the plans. though ellicott made revisions to the original plans, including changes to some street patterns, l'enfant is still credited with the overall design of the city.
