College of Alameda's Campus Entry Improvement Project

The College of Alameda, one of four Peralta Community Colleges, renovated its campus entry landscaping as part of its Sustainable Peralta campaign. This initiative aims to enhance economic opportunity and community well-being while protecting and restoring the natural and social environment upon which our neighborhoods and economies depend. The new entry landscape makes a visible statement about the College's commitment to environmental stewardship and signifies a move away from traditional resource-intensive landscape designs.
