A staircase from Mission Street leads up to this popular sun terrace. Its main feature is a black granite wall with fissures spouting water into two pools where undulating glasspanels evoke waves. The rectangular terrace is designed on a 45-degree grid, featuring many planter beds and terraces forming intimate spaces. Planters with trees, flowers and grass all have ledges at sitting height. Designer café tables and chairs. Deli at foot of stairs. Open at all times. Needed improvements: restroom availability.
