Sacramento, CA

Quadriga was part of a collaborative design build team for  Ernest E. Tschannen Eye Institute I UC Davis Eye Center. The team goals were to create a unique inspirational design, an improved patient experience and a place where the human to nature connection is prominent.  The biophilic design, one that depends on a sustained engagement with nature, has been proven key advancing people’s health, fitness and wellbeing. 

The site design, drawn from the form and movement of rivers, provides harmony between efficient circulation and engaging usable exterior spaces.  Applying this principle, circulation routes maximize efficiency and ease of passage of pedestrians throughout the site.  Gathering spaces form eddies for rest and activity without impeding the flow of circulation. Together, the gathering spaces and circulation routes form a cohesive site, but their distinction remains clear. 

 The visually impaired user utilizes distinct changes in paving texture and color between seating areas and clear paths of travel for wayfinding.  Covered walks reinforce wayfinding to the building entrances while providing protection from the elements. 

Santa Rosa, CA

The Burbank  Theater modernization  project was the first project as part of the Measure H Bond measure- this much anticipated  modernization included  interior renovations, the addition of a black box theater and important  exterior upgrades. Quadriga collaborated to improve accessibility, provide a welcoming entry and forecourt and maintain several heritage oak trees that surround the existing theater. An important experience for theater patrons  and students was the existing front steps and small forecourt. These undersized elements have long been a gathering point and a place to stop and discuss performances.  Our team expanded the forecourt integrating the access and provided seating and additional gathering space for intermissions. A reserved planting palette was used to integrate the new black box theater into the historic core of the campus.

Sacramento, CA

The site design for the natural sciences building was to create a cohesive and highly flexible STEM Courtyard at Sacramento City College. The new space includes a shaded outdoor classroom space for up to 30 students at a time; outdoor study and gathering space with flexible & collaborative site furnishings; small outdoor gathering nodes with informal seating set into the garden environment; a STEM Garden, planted with a diverse and enveloping garden designed to reinforce the vision of the courtyard as a teaching and learning space and support the Biology Department’s outdoor curriculum and a raised “laboratory” planter beds for use with the Biology Department’s Curriculum.

Occidental, CA

The Harmony Union School District is comprised of over 700 students in two schools co-located on a single campus.  Harmony Elementary School includes pre-K through 1st grade, and Salmon Creek School includes grades 2-8.  The 56-acre campus contains four habitats: Salmon Creek, redwood forest, perennial wetlands, and grasslands.  The campus facilities also include a sports field, a paved playground, multiple natural and student-built outdoor learning areas, a nature trail, an observation deck overlooking a waterfall on Salmon Creek, and a ¾-acre working garden that contributes to the lunch program and the school farm stand.

 Quadriga worked with the Team to build upon the District’s environmental sustainability and educational framework by providing accessibility upgrades, improving outdoor learning environments, adding areas for structured and imaginative play, renovating a drought-tolerant youth soccer field and jogging path, and capturing and reusing over 500,000 gallons of stormwater runoff  to offset well draws that  would impact the adjacent neighboring Salmon Creek.  This large cistern was developed as an amenity and infrastructure as it is equipped with a vegetated roof and “performance stage” to blend in with the neighboring marsh and redwood forests while also being an outdoor classroom.  These improvements will continue to improve the health and performance of the students, staff, and their local environment.

Santa Rosa, CA

This award-winning project provides integrated patient care in a campus like facility.  The landscape provides softness and greening to the multi-story structures.  Evergreen vines climb four stories on greenscreens to provide scent and color to the parking garage-while native plants intermixed with  seasonal flowering  provide interest year-round.  The site design includes  circulation  from the garage to the medical center via a  formal plaza while storm water management engages a slightly different planting approach. The perimeter planting is more native in feel, while swales are reminiscent of the Sonoma County roadside drainage swales- with breezy grasses and  white umbel flowers.

Petaluma, CA

Quadriga was part of the design build team of this new indoor and outdoor classroom space for the Loma Vista Immersion Academy, an existing elementary school campus that needed updating and expanding. An underutilized area on the campus was converted into two new classroom buildings and multifunctional courtyard spaces. The courtyards include a variety of seating options: rows of benches for lecture-style teaching, round tables for small-group discussions, and picnic tables for hands-on lessons. Each outdoor classroom area doubles as a space for students to socialize and eat lunch. Materials, such as wood slat benches and picnic tables, complement existing campus furnishings, harmonizing new design elements with existing conditions. Finishing details, such as a custom outdoor markerboard, curvilinear concrete seat walls, and Sonoma field stone boulder seating augment the space.

Santa Rosa, CA

The Santa Rosa Memorial Hospice House will serve the terminally ill and will make the end‐of‐life experience less stressful for those who need it most. A welcoming environment and dedicated staff that can take charge of caregiving ‐ sharing their expertise, compassion, and guidance ‐ is what many families and patients deserve. Encouraging patients and families to explore the outdoors was incredibly important from a use and visual connection perspective. Each room has access to the outdoors through a private patio enclosed by low stone walls and evergreen plantings. Small seating nooks dot the rear courtyard providing options for residents and families to relax in a garden of native oak trees, familiar perennials, and lush evergreens. A larger plaza space allows for more engagement and gathering opportunities and is accented by a small water feature to that enhances the senses and provides a buffer to adjacent noise for those enjoying the gardens. Several specimen oaks trees are planned for the site to build upon the adjacent urban forest and provide a sense of enclosure, security, and connection to the broader County ecosystem.

Santa Rosa, CA

Jeff Kunde Hall is a flexible office, classroom and courtyard setting that is designed to accommodate the fluctuating needs of the growing Santa Rosa Community College (SRJC) campus. The courtyard and surrounding landscape were designed to be adaptable and offer many uses. Custom wood platforms provide flexible seating compatible for both individual study and outdoor classroom use. Fluid pavement patterns and a diverse planting palette draw the user into the space both visually and experientially, supporting a calm and focused learning environment as well as providing a conduit through which students can easily move.

Sacramento, CA

Quadriga was part of the design-build team that developed a new parking structure and Welcome Center building for the entry to the Sacramento State University campus. Quadriga’s plaza design bridges the space between the Welcome Center and parking structure and forms a strong connection to the rest of the campus. In addition to an active plaza area, the multi-faceted landscape includes integrated bike parking, stormwater management, the preservation of existing trees, and the creation of native landscape areas associated with the adjacent campus arboretum.

Davis, CA

Located in the West Village area of the UC Davis Campus and operated by the Los Rios Community College District, the Davis Center Phase II building is a 3-story building containing science labs, offices and classrooms. Quadriga developed a new central plaza that forms a cohesive quad space between the new phase II building and the existing phase I building. As additional buildings are built in the future, the central plaza will remain the site’s anchor. The plaza design includes a bosque of shade trees, provides a variety of seating opportunities which can accommodate small visitor groups as well as large student crowds, and is situated between two rain gardens. The Davis Center Phase II project is LEED Silver certified.

Roseville, CA

Quadriga provided design and construction document services for the renovation of Sutter’s Emergency Department Expansion new landscape and plazas in Roseville, California. The plazas were designed to incorporate existing drainage features and address water use concerns while providing a unique landscape identity for the site that responds to its natural oak woodland surroundings. The design also provides healing and contemplation gardens. The overall site design includes a linear plaza zone, a terminal plaza zone, multi-level interior courtyards, extensive bioswale features, low water use native plantings, and a high-efficiency irrigation system.

Fairfield, CA

Quadriga, along with team members, DPR Construction, HGA Architects and BKF Engineers, designed a 2.4-acre science center for the Solano Community College. Its central location on campus demanded careful circulation planning. The main circulation routes surrounding the building serve as campus thoroughfares yet maintain association with the science center. An entry plaza, equipped with an outdoor stage and classroom area, creates a sense of arrival.

Central to the building are three courtyards that provide outdoor gathering areas for students to study and socialize. The smaller two courtyards are arranged as flexible and comfortable spaces for small groups and single occupants. The largest courtyard includes curved seat walls and a paving pattern inspired in form by a DNA double helix. The inclusion of science-related geometric forms, like hexagons and helices, reinforce the building site with a sense of place.

The surrounding college campus landscape is predominated by lawns and foundation hedges. Working in conjunction with campus horticulturalists, Quadriga established a landscape character that complements its context yet encourages sustainable lawn alternatives. A palette of both native and adapted plant species evokes the aesthetic of the nearby California foothills. Trees are placed to help frame preferred views, screen undesirable views and abate strong delta winds.

Sonoma County, CA

Quadriga, in partnership with HGA Architects and Brelje and Race Engineers, designed a new 25 acre healthcare campus that includes a medical center, physician’s hospital and medical office building. Sutter Health is committed to providing buildings that meet or exceed LEED certification. Toward that goal, on-site storm water is filtered through bioswales and plant materials are selected specifically for their low maintenance requirements and low fertilizer and water usage.

Crucial to the success of the project is the health and well-being of users. The new state-of-the-art Medical Center replaces an existing building that is not seismically sound. Vehicular and pedestrian movement was studied intently with the goal of providing a stress-free visit for hospital visitors and those attending events at the Wells Fargo Center. 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 viewing garden, enclosed by gabion walls, contains seat walls and water features that create a space in which visitors can reflect and relax. The garden, entered on the ground floor, can also be viewed from inside through an adjacent 2-story glass wall. Other outdoor seating areas have space for small to large groups as well as single occupants. All outdoor spaces share common furnishings and materiality.

Santa Rosa, CA

Quadriga worked with TLCD Architecture and BKF Engineers on the expansion of the campus facilities and improvement to the children’s playground. To accommodate the growing needs of Wright Elementary school a new Multi-Purpose building and student drop off were added. Landscape materials were selected for drought tolerance, exposure, and for their compositional value. The landscape design references plant communities and conditions found in nature to integrate landscape-based learning opportunities with the campus. Water is highlighted on the Campus through the collection and release of rainwater in playful and educational ways; A rain catchment is fitted with a hand pump for watering a student herb garden and, a purposefully directed downspout becomes a rain activated waterfall that feeds a cobbled detention area, showcasing the hydrologic cycle.

Napa Valley, CA

The McCarthy Library represents a significant development of the campus redevelopment and expansion initiative. Expanding upon the campus pedestrian mall, the project situates a large urban plaza at the south end of campus in an effort to strengthen the pedestrian core and set the stage for a new campus design typology that accommodates new site uses. While taking cues from the existing campus landscape, tree groves, native and adapted planting beds, and open paving, the plaza supports pedestrian navigation through the site. A series of low site walls and integrated benches frame a mix of passive and active uses for the community, encouraging both students and members of the general public to congregate for cultural, social, and political events, as well as commencement and ceremonial gatherings.

Saratoga, CA

As part of a campus modernization, the President of West Valley College intended to create a main entry that reflected the Campus objectives of academic quality, sustainability and inclusiveness. Central to the project objectives would be creating a public face that was useful, beautiful and sustainable.

The entry design expanded from a monument sign with landscape to a dynamic entry to the campus. The existing land form was pushed, pulled and nudged to provide curves and depressions to hold stormwater and to accentuate plantings and a new custom entry sign. Two historic palms were moved from the original farmhouse to a more prominent location where they frame a newly planted native oak nursery. The native oak nursery will be managed as part of the overall campus tree succession program.

Quadriga was teamed with TLCD Architecture and GNU Group. 

Davis, CA

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.

Napa, CA

Napa County purchased a 25-acre laboratory campus and is incrementally converting former research and development space to functioning public health services, office, and support space. A unique part of the conversion is the new space for the Therapeutic Child Care Center (TCCC). The Center provides enhanced infant-parent mental health and child development services for ages ranging from newborn to five years.

Unique and intentional siting was required, for privacy and security concerns, to best serve such a vulnerable clientele. The former loading dock and warehouse space was selected as the best space for the TCC Center and required exceptional engineering and fill operations to transform the dock into useable outdoor play yards.

The new exterior play yards are soothing in color and lightly programmed, by design.  The yards are surfaced in resilient rubberized play surfacing and artificial turf grass, shaded by overhead sails and are enclosed by custom privacy fencing.  Each play yard is separated based on age group and has visibility to the adjacent play yards for socializing.  Storage for the faculty comes in the form of converted shipping containers, something that was crucial for day to day operations and honors the locale’s former life as a warehouse space.

Davis, CA

Quadriga in collaboration with Far Western Anthropological Group worked with the University and the project committee to create an interpretive plan, marking eleven sites throughout the campus to inform and remind visitors of its rich past, long before Davis ever existed.  Through many meetings with the committee and consultations with Patwin tribal members, the schematic plan was finalized.  Ten installations include vertically mounted basalt columns with text engraved, in various compositions with paving and planting.  The primary installation is located near Putah Creek in the arboretum and has been referred to as the “Reflective Area”.  This memorial includes basalt columns, as described above, and a path leading to a “coiled” seat wall which terminates in the center with an engraved basalt column listing 51 Patwin People who were removed to missions in the early 1800’s.  Quadriga prepared construction documents for the Reflective Area.

Fresno, CA

The New Student Union at Fresno State provides a welcoming and dynamic space for students and visitors. The entrances to this state-of-the-art building are surrounded by flexible plaza spaces populated with trees and movable seating. To the rear of the building, a stepped lawn amphitheater is surrounded by plantings that evoke the Sierra. Project plantings were chosen based on their seasonal interest, adaptive nature, and low water use.

This project is LEED gold equivalent.

Santa Rosa, CA

The Santa Rosa Junior College’s Lindley Center for S.T.E.M. Education is the first of three phases in a new state-of-art Science and Math core. The three-story building will be equipped with the latest teaching and lab technology as well as multiple areas for gathering, course break-out sessions, and socializing.

Its location on campus demanded careful circulation planning and open space analysis. The circulation system is designed to function as a campus thoroughfare while providing generous forecourts and seating areas associated primarily with the building. Multiple seating areas are incorporated using raised planters, planted mounds, and lawn areas with movable furnishings below large existing heritage oak trees.

The outdoor spaces are designed to build upon the existing character of the campus. Site materials were carefully selected to support active learning in sciences, technology, engineering and mathematics. The plants, stones/boulders, paving material geometry and stormwater are all on display and integral to the curriculum.

Sacramento, CA

Quadriga worked with the faculty at Camellia Waldorf School to develop a master plan for their recently purchased campus. Quadriga held a series of visioning meetings throughout the master planning process with faculty, staff, parents, and students in order to gain a complete understanding of the school’s needs and desires as well as their unique approach to learning. A master plan was developed that sought to maximize use of the campus’ limited space and budget. The final master plan was further refined into recommended phases, giving the school tools for proceeding at their own pace and within the framework of their unique hands-on, community-oriented methodology.

Santa Rosa, CA

The Charles M. Schulz Museum and Research Center celebrates the work of its namesake, the creative force behind the Peanuts characters and cartoon strip. With the museum at capacity, a separate education building with two classrooms, restrooms, and storage, was designed for the west side of the property, abutting the Children’s Museum of Sonoma County. Quadriga was tasked with designing a fun, playful outdoor space to match the lively energy of the museum. Shade trees and planting surround a lawn expanse that is defined with play berms shaped in the silhouette of Peanuts’ most beloved dog, Snoopy. The outdoor area encourages unstructured play and allows children to explore the landscape in an unrestricted way.

Rohnert Park, CA

Situated in the northeast quadrant of the Sonoma State University campus, adjacent to Copeland Creek, this facility occupies nearly 50 acres. The Green Music Center includes two primary performance venues: a 1,400-seat concert hall and a 300-seat recital hall. The facility will be home to performances by the Santa Rosa Symphony and host performances by the San Francisco Symphony, the Bach Choir, and SSU’s varied musical programs.

Enjoyment of concert hall events will extend to an outdoor viewing lawn, a place for patrons to gather and relax. A rolling landscape provides a rural backdrop to the facility and helps create a protected acoustical environment.

The project incorporates storm water detention ponds, vegetated swales, and additional wetland features, the area is visually connected to the adjacent riparian zone of Copeland Creek. The design welcomes pedestrians as they transition from the parking lot to the music venue.

Sacramento, CA

Working in collaboration with the University and Project Architect, Quadriga developed comprehensive landscape and circulation master plan for California State University, Sacramento.

In response to campus wide drainage issues, resulting in campus flooding and inefficient and dated storm water infrastructure, the master plan builds upon the campus-wide “Greenway” storm water infrastructure system. Moreover, through site investigations of the CSUS sub watershed, the campus currently collects and moves all storm water directly into the American River untreated. The Greenway aims to treat and mitigate storm water runoff through hyper-accumulators plantings and innovative irrigation techniques to reduce pollutants directed to the American River.

A new landscape management program delineates the care of existing mature trees and the goals of future tree plantings. Additions made to the existing tree canopy enhance species diversity and reflect a density similar to the campus arboretum. Expansions made to the arboretum will incorporate spaces designed for community outreach.

Existing circulation patterns are modified to increase pedestrian permeability by allowing movement through existing large expanses of lawn and shrubbery. In doing so, campus users are able to easily navigate to destination points.

The landscape and circulation master plans guide campus development in the management of existing and future landscapes, streamline circulation systems, and create campus identity.
