PERMEABLE PAVING DEMONSTRATION PROJECT
The project improved the appearance, accessibility, and safety of the UC Berkeley campus Botanical Garden entrance. The project took a space that was enclosed by a chain link fence, paved with a bare, aging asphalt surface, and an inaccessible and unsafe cross-slope, into a safe, attractive, accessible, and functional entrance befitting the world-renowned stature of the Garden’s collections. Tall, sturdy concrete columns with an overhead trellis anchor custom metal pedestrian gates leading to planted terraces connected by broad steps and a sloping path. A separate gate at a lower level accommodates vehicles. Bard and batten wood fencing encloses the ticket booth and terraces, providing an appropriate backdrop for the Garden sign at the new drop-off area.
Project sustainability features:
- Pervious concrete slows the rate at which storm water flows into nearby Strawberry creek, improving the water quality in the Creek and eventually, San Francisco Bay. The installation represents the campus’ first use of permeable paving and was achieved as a result of a donation. The Botanical Garden program staff use the area to demonstrate the permeability to Garden visitors and to educate them on the benefits of slowing storm water flows.
- Drip/micro-spray irrigation provides the minimally required water for the climate-appropriate planting. ET Water controller includes a weather station that permits the irrigation to be responsive to localized weather conditions.
- Plants used are drought resistant and low water use.
