The concept adopts the ideals of the traditional European city, combining them with a revo-lutionary idea: A circular lake with a 2.5 km diameter forms the core. The image of concentric waves, produced by a drop hitting the water surface, is the principle metaphoric image of the overall city structure. The use structure is divided into radial rings from the inside to the outside: promenade, business district with high density, 500 meter wide ring-shaped city park, block-like residential districts for 13,000 people each situated along radial roads accord-ing to the principle of a compass card. Wedges of landscape reach into the city as far as the second ring. Watercourses and small lakes penetrate all districts.
