Quadriga was founded in 1997, and is a firm of 12 landscape architects, planners, and designers who specialize in innovative, functional design solutions. We apply a team approach to respond to the opportunities and challenges presented by each client’s circumstances and each site’s particular landscape character. Under the leadership of five principals, the group uses the insights gained from their collective years of practice to develop functional and aesthetic design work.
Our success stems from experience, insight, and enthusiasm with 8 of our design professionals licensed Landscape Architects. From our offices in Sacramento and Santa Rosa, we apply this energy to a variety of public and private projects throughout Northern and Central California as well as Nevada. Quadriga’s guiding vision ensures that we are always contributing to a legacy of excellent planning and design—a legacy that has always balanced stewardship and a respect for cultural context and spirit of place with solutions that are constructible and financially viable for our clients. At Quadriga, we actualize this vision by combining high professional standards and sound business practices with a dynamic working environment to encourage growth and innovation.
Quadriga strives to apply LEED (Leadership in Energy and Environmental Design) and Sustainable Sites Initiative (SITES) philosophies whenever possible.

Fair Oaks, CA, USA
Healing Garden demonstration garden
In 2003, the Fair Oaks Horticultural Center added a new half-acre landscape demonstration garden to their community garden complex. Quadriga’s design for this garden introduces home gardeners to therapeutic and healing plants; as well as water efficiency concepts, native plant use, and sustainable landscaping materials.
An arbor-circled open space serves as classroom for the many instructional events held at the center, and meandering pathways lead visitors past a California native plants garden, a Mediterranean-style garden, perennial flowerbeds, an herb garden, and more. The pathways and other hardscape in the garden display a mix of poured-in-place permeable paving, permeable unit pavers, and colored concrete. The curvilinear low walls allow visitors to interact with both surface-level and raised planting areas, and also serve as seat walls.
This well-executed water efficient landscape, with efficient irrigation throughout, reinforces the teaching and hands-on nature of the Center’s Master Gardener-led classes. The Quadriga team also researched, wrote, and designed the graphics for the demonstration garden’s comprehensive signage.

Acute Care General Hospital
Sensory Viewing Garden
Quadriga is currently designing a new healthcare campus which includes a medical center, physician’s hospital and medical office building. Crucial to the success of the project is the health and well being of the users- as such much thought is put into the design and placement of public areas, gardens and pedestrian way finding on the campus. Sutter Health is committed to providing buildings that meet or exceed LEED certification. Toward that goal, on site storm water is filtered through more sustainable bioswales and plant materials will be selected specifically for low maintenance, fertilizer and water use.
Set on a 25 acre site adjacent to the Wells Fargo Center, the new hospital will be LEED Certified and the grounds are designed to implement the newest stormwater and water conservation ordinances. On this site, way finding and efficient circulation are critical for hospital visitors and those attending events at the Wells Fargo Center. Vehicular and pedestrian movement was studied intently, with the goal of providing as stress free a visit as possible. Signage and plantings were designed to provide both literal and subliminal way finding clues. Tree and vegetation patterns were designed to help guide the visitor through the site.
Outdoor spaces are designed to meet the needs of the hospital staff as well as patients and visitors. The most reflective space- the viewing garden - has seating walls, water features, gabion walls and visually relaxing proportions. The garden can be entered from a ground floor waiting room and can be viewed through the 2 story glass wall. Other outdoor seating areas have space for small to large groups as well as singular occupants. All of the outdoor spaces have a common vernacular of furnishings and materials.

Davis, CA, USA
Student Primary Care Facility
The design for the grounds reflects Quadriga’s sustainability effort through low water use design, tree preservation, permeable paving, and the first green roof on the UC Davis campus. Additionally the design provides students, faculty and visitors the opportunity to reflect in the healing garden and exercise on the circular exercise path.
The new 77,000 square foot Center is a comprehensive facility focused on programs for the student, providing primary care services, specialty clinics, counseling, women’s health, and health education. In addition, the project is designed to meet the UC Davis Green Building Guidelines and is seeking LEED Gold certification.
