sentences:  The design of Embarcadero Plaza is credited to Don Carter (principal-in-charge) with help from Mario J. Ciampi and John Bolles.The original concept was devised by Lawrence Halprin, who described five distinct districts of Market Street in the 1962 report "What to do About Market Street" starting at the Embarcadero and ending at Van Ness.In retrospect, Halprin's vision for Market was described as a "pedestrian-oriented series of linked civic spaces" which were later realized as the open spaces running from Embarcadero Plaza (in the northeast) to UN Plaza in the southwest.
