The Commission's first chief surveyor was Charles Frederick Loss, who, like Mangin and the deceased Goerck, was an officially recognized city surveyor, a position he received contingent on becoming a naturalized American citizen. Unfortunately Loss did not appear to be a very competent surveyor, as several of his ventures had serious errors, which eventually resulted in his being relieved of his position in 1811. Loss exhibited the same lack of ability as the chief surveyor for the Commission, and finally the Commission made an agreement with Loss that he would do only the first task that had been assigned to him: to make a map of Manhattan island, and get accurate measurements for the location of certain streets which would provide a framework for the plan of future streets. For this, Loss would receive no wages but a simple fee of $500. (). Loss was to deliver the map by May 1808.
