For those who travel La Jolla Village Drive, are part of the UCSD campus community, or frequent performances at the La Jolla Playhouse, a greatly improved south campus entry experience awaits. A once unused yet irrigated lawn along North Torrey Pines Road is now a campus stormwater feature. It is an inviting space; a visually pleasing waypoint for drivers, but also caters to the numerous pedestrians and bicyclists who travel this campus route daily.
The Ridge Walk Rain Garden is designed to conserve water resources, improve water quality, attract wildlife, and promote watershed stewardship. The Ridge Walk Rain Garden features low-impact development (LID) practices that work with nature to manage stormwater as close to its source as possible by incorporating landscaping techniques to detain and slow runoff from adjacent sites, filter it, and improve the water quality of runoff to the ocean. The eco-friendly landscaping encourages water conservation with native and drought-resistant plants.
Boulders, cobble and strong-rooted, erosion-resistant vegetation are planted along the swale and in the basins to reduce water velocity and prevent erosion. Densely-planted vegetation in two basins filter out trash, debris, and suspended sediment. The Ridge Walk Rain Garden includes a wide variety of hardy, drought-tolerant plants that help save water, as well as produce unique and intriguing flowers across the color spectrum. From the California Goldenrod to the Hummingbird Sage, each plant species was carefully chosen and arranged in areas based on watering needs. This low water landscaping supports water conservation and encourages a healthy ecosystem.
