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
Camp Newman is a beloved summer camp and retreat center tucked into the Mayacamas mountains Northeast of Santa Rosa. The Camp was mostly destroyed in the 2017 Tubbs fire and after the devastation they underwent a thorough master planning and fire scaping process. To rebuild as quickly and economically as possible, the URJ selected a Design Build team, led by FDC. The first phase to open Summer 2021includes a new Community Center, Dining Hall, large sports field and community plaza referred to as the “Kikar”. Extreme care has been taken to respect what was admired about the original camp while improving facilities for an even better experience.
Creating a camp environment that embraces the campus’s Jewish heritage, planned with intensive fire safety measures, as well as respecting the stunning site’s landscape was the goal. Large communal gathering spaces play fields for organized games, intimate areas for group campfires, and regeneration of the site’s tree cover are all being implemented. The heart of the camp is nearly complete, and the campers are eagerly expected.

“We aim to support students, even outside the classroom. And what many students need right now is a place to live.” - SRJC President Frank Chong
Quadriga collaborated with HPI Architecture and BkF Engineers to develop student housing that maximizes views to the existing campus, buffers Highway 101, provides seamless connections to the campus core, and creates pleasant outdoor experiences for 350+ student residents.
Central to the SRJC Master Plan Goal, the large courtyard, or Commons, is a critical link to the larger campus circulation yet separate enough to encourage social interaction and to provide areas of refuge and reflection. The space is organized around a central sloping lawn coupled with tiered seat walls beneath a tree allée to provide multiple opportunities for lounging, gathering, and relaxing. Circulation around and through this space is intuitive and generous to encourage walking, skating, and biking from home to school. It is designed to be expanded as formal connections extend into the campus core. An open pit BBQ, raised beds, and gathering tables provide opportunities for residents to relax and enjoy the outdoors while preparing food and interacting with their neighbors. Generous tree plantings will act as a continuous living roof for all the outdoor experiences.

This Senior affordable housing project replaces mobile homes destroyed during the Tubbs fires of 2017. The City and development partners advocated for federal funding to rebuild this much needed affordable housing and were successful in obtaining funding to create three beautiful and sustainable buildings. Residents who lost their homes maintained a community in the face of many challenges and many of them call Laurel home.
The design is based in the principles of health, wellness and active living. Each of the buildings is connected by a walkway which extends around the entire project site connecting the buildings with the street frontages, courtyards and garden areas. The interconnected walkways provide ample pedestrian circulation allowing for walking in ever growing circles based on a resident’s capability. The courtyards are interconnected and provide outdoor gathering and activities space allowing for extensive gardening and encouraging both healthy eating as well as exercise. The focus of each courtyard are the gardens, with raised planters for residents to participate in growing food, flowers and plants.
Chico, CA
The new Behavioral and Social Science Building is designed to optimize learning and engagement through indoor/outdoor connections. Located along Big Chico Creek, the landscape site design aims to unify the natural riparian landscape and interior of the building. A river overlook plaza provides a flexible space for outdoor learning and opportunities to view the creek. Permeable pavement, rain gardens, and native riparian plantings emphasize the focus on environmentally responsible design.
An interior 3- story atrium extends the native riparian landscape of the site into the building providing spatial definition and biophilic connection into the building.
This project is targeted as LEED Gold
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.

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.
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.
Sebastopol, CA
The design for Exchange Bank’s new Sebastopol branch was highly influenced by the agricultural heritage of its surroundings. Drawing from clean forms and opposing geometries of the historic Sebastopol apple orchards, the landscape creates a rich planting tapestry. Stormwater planters are integral to the landscape and were arranged to accept roof runoff from a single point, drawing attention to the striking angle of the building’s shed roof.
The project was awarded a Top Real Estate Project Award by the North Bay Business Journal in 2020.
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.

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.
Sacramento, CA
Olympians Park is a 3.4-acre neighborhood park that sits within an urban infill housing development, The Mill at Broadway, located near downtown Sacramento, CA. The park is designed to be a destination for both residents of The Mill and visitors from the Sacramento region. As a dense urban site, homes within the community afford little private outdoor space. The park design reflects this need for an outdoor space that serves as a community’s backyard. The park is organized into a multifunctional set of outdoor rooms that include an amphitheater, a picnic and BBQ area with a bocce court, a dog park, and an event lawn. A quarter-mile bike and jogging trail circumnavigates the park and connects to a larger bike network that leads to the Sacramento river and to downtown.
The overall community, including the park site, was once occupied by the Setzer Box Company, a family-owned sawmill that manufactured wooden fruit crates. Relics of the site’s industrial history were incorporated into the park’s design. An existing 39-foot-high sawdust hopper that was an original part of the Mill operations was reimagined as an iconic monument. The park’s bike and jogging trail now runs underneath the hopper, which was adorned by mural artist, Jose Di Gregorio.
Olympians Park opened in May 2020.
Santa Rosa, CA
Quadriga was happy to donate our time to the Luther Burbank performing Art Center to help create the Marcia and Gary Nelson Family Grand Plaza. Conceived of as an extension of the lobby space, the Grand Plaza provides a beautiful gathering space for patrons to visit before and after performances and for special events. A central patio and lawn space are surrounded by custom weathering steel fencing, punctuated with groves of olive and maidenhair trees. Sculptural succulents, swaying grasses, and the twinkle of overhead string lights add drama to this center for the performing arts.

The Paradise Ridge Event Center is slated for re-opening and a fire memorial event late November 2019.
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.
Sacramento, CA
Responding to the needs of the local community and the majority of rental properties with little access to secured open space, Quadriga developed pro-bono designs to transform the vacant lot on 19th and Q Street into an urban dog park. Working closely with Capitol Area Development Authority (CADA), CADA and Quadriga rallied stakeholders, City officials and the City’s Parks and Recreation Department to amend the future use of the parcel (slated as a standalone plaza) to be reconceived as a dog park. Conceived as a multi-use park, Brooks Truitt Park supports a public plaza, designated dog play areas, community garden and public art installation for Sacramento’s Midtown area. The master plan for the site was revised and was unanimously approved by City Council Fall of 2015. Brooks Truitt Park is unique due to its urban setting and reduced size. As such, it will fulfill multiple needs in the neighborhood: designated dog play area, plaza, community garden, etc. To address the urban nature of the park site, we wanted to ground the dog play areas within a robust tree canopy, framed by native/drought adapted plantings and contemporary lighting fixtures and furnishings. Visitors will be greeted by a large word sculpture that spells “BARK” at the center or a large plaza that we hope creates an iconic landmark for the park and the community.
Sacramento, CA
Situated within the historic State Capitol Park and located directly across the street from the State Capitol entrance, the original monument, a lone soldier known as “El Soldado” dedicated to honor California’s Latino Veterans, was in need of enhancement. Quadriga was retained by the California Mexican American Veteran’s Beautification and Enhancement Committee to develop a design which complimented and elevated the presence of “El Soldado.” The memorial experience is a self-guided sequence beginning with recognition of the Society of War Mothers who commissioned the creation of the memorial in the 1950s. A large circular plaza surrounds the monument, allowing for access to the monument and provides gathering and contemplative spaces for visitors.
West Sacramento, CA
Subtile, a public art piece situated on a levee in West Sacramento, overlooks the Sacramento River. Quadriga worked with the Czech artist, Federico Díaz, to site the sculpture. The site was selected based on two criteria. First, it provides optimum views to and from the sculpture. Additionally, as the sculpture is composed of reflective stainless-steel disks, it reflects its environment. The sculpture is sited where it can best reflect both its surrounding urban and riparian setting.
The project team provided engineering, lighting and landscape drawings. Because the sculpture is placed within the levee easement, Quadriga lead the effort to obtain permits from the Central Valley Flood Control Board, the City of West Sacramento, the U.S. Army Corps of Engineers and the California Department of Fish and Wildlife.

Santa Rosa, CA
Quadriga collaborated with the owner, architect and civil engineer to create a unique landscape identity for the American AgCredit Headquarters, located at the entry of the Sonoma County airport. Quadriga designed a state-of-the-art irrigation system to support plantings that characterize an agrarian landscape amidst an urban environment. The building envelopes the central courtyard and nearly all of the interior spaces have a view of large specimen oaks and grassy hillocks. The courtyard seating is a variation on a stylized tree limb and is positioned to provide group and intimate seating options for employees and visitors. Linear walkway pavers align with patterns inside the building to blend the interior and exterior spaces.
Agua Caliente, CA
Located in the center of the Sonoma Valley, Fetters Apartments is a low-income housing project in historic Agua Caliente. Once the northern border of Mexico, the area has a colorful and storied past, one that we tried to honor. Mature, existing Canary Island Date Palms were saved and relocated throughout the site to help anchor the buildings. They also helped define the aesthetics of the new plant pallet. Fetters Apartments is the first phase of the Sonoma Springs Mixed-Use Project that, once completed, will provide housing for 140 families and seniors, neighborhood improvements such as connection to the Sonoma Valley Bike Trail, upgrades to the Sonoma Charter School play field, and a community garden.

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.
Kenwood, CA
Drawing from the oak woodlands and the Valley of the Moon vineyards, the design for the Kenwood residence reflects the landscape character of the valley. Upon arrival to the residence, visitors meet a custom wood entry house and steel gate along the frontage road, framed by stone columns and native vegetation that blend the property into the hillside landscape. Visitors move through a meandering driveway flanked by wood split-rail fencing and planted berms. A large lawn event space accommodates informal gatherings and family softball games overlaid by a grove of trees. Terraces and gardens bound the residence providing areas for outdoor dining and lounging.
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.
Folsom, CA
Quadriga was hired by the City of Folsom to work with Chong Partners Architecture in the preparation of a long-term master plan for the Railroad Block. The design intent of the Railroad Block is to honor and reflect this area’s extensive past from the days of the Gold Rush including the engineering of the Sacramento Valley Railroad in 1856, the terminus of the Pony Express, and the Folsom Powerhouse. This specific block stands in the precise location that the Sacramento Valley Railroad occupied and its recognition is emphasized in the design of this space; it is acknowledged with a commemorative rail line that follows its original path.
Quadriga prepared design and construction documents for the plaza adjacent to the new light rail station at the western side of the block. This area includes the commemorative rail line that will continue further as the rest of the block is developed. The plaza is meant to accommodate large numbers of commuter and tourist visitors coming to Folsom via light rail. A simple plant palette dominated by a grid of large canopy trees creates a shaded urban plaza. Materials used in the plaza match those in the light rail station, as well as elements in the existing district. This design process took us through several productive meetings with the City’s Historic District Commission, ending in their final approval.
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.
Roseville, CA
Quadriga assisted the City of Roseville in Master Planning for a 7.8-acre neighborhood park adjacent to Fiddyment Farm Elementary School. The park includes soccer fields, exercise stations, a comfort station, parking, a picnic area and a playground. A planted storm water retention area helps to reduce drain inlets, other storm water structures, and improves water quality.
The park design incorporates elements that honor the agricultural history of the area, specifically pistachio farming. The playground features custom climbers like stacked pistachio crates, sheep, pistachio nut crawl-throughs, and a tractor. To evoke the orderly layout of an orchard, many of the trees are arranged in distinct rows.
Following the master planning effort, Quadriga completed construction documents for the park. Laurel T. Stizzo Park was dedicated on June 30, 2018 and is open to the public to enjoy.
Santa Rosa, CA
Quadriga led the site design and implementation efforts for the relocated Luther Burbank Savings headquarters in downtown Santa Rosa. As part of the urban revitalization developments in Santa Rosa, the project involved treatment of the street frontage, courtyard and parking area. A private courtyard, framed by a custom steel and wood enclosure, provides visitors a respite from the adjacent transit mall. Locally sourced materials include salvaged granite stones from San Francisco’s Union Square. Granite cobbles demarcate parking stalls, and underground structural soil reserves support a robust tree canopy, providing ample shading for the parking area. Storm water management strategies include bio-swales and rain gardens to capture and treat urban runoff and planting selections consist of native and adapted species.
Stockton, CA
An urban infill project, Zettie Miller’s Haven provides affordable housing within an existing Stockton neighborhood. In addition to housing units, the project includes a common space with picnic and barbecue areas and a multi-functional lawn that also serves as storm water detention and emergency vehicle access. Additional storm water treatment is provided by swales around the perimeter of the site that are planted with vegetation that thrives in both wet and dry conditions. In addition to creating vibrant and functional planting areas throughout the site, Quadriga made it a priority to establish a tree canopy that will eventually shade much of the outdoor space and provide natural cooling for the building.
Fair Oaks, CA
In 2003, the Fair Oaks Horticultural Center added a new half-acre water efficient landscape demonstration garden to their community garden complex. The garden introduces home gardeners to water efficiency concepts and native plant and landscape materials. An arbor-circled open space serves as a classroom for the many instructional events held at the center, and meandering pathways lead visitors to a California-based native plants garden, a Mediterranean-style garden, perennial flowerbeds, and herb garden. The pathways and other hardscape in the garden display a mix of poured-in-place permeable paving, permeable unit pavers, and colored concrete. Curvilinear low walls allow visitors to interact with both surface-level and raised planting areas, and also serve as seat walls. Quadriga researched, wrote, and designed the graphics for the demonstration garden’s original comprehensive signage.
San Mateo, CA
In collaboration with Jon Worden Architects and the Mid-Peninsula Housing Coalition, Peninsula Station is a high density, transit oriented, affordable multifamily housing project located in San Mateo, CA. Resting atop of an underground parking garage, the design responds to an “on podium” condition with raised planting areas and integrated storm water treatment system. Semi-private patios, outdoor common areas, a community garden, commercial street frontage, and play areas support various amenities for residents.
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.

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.
Yuba City, CA
Shortly after the Tierra Buena neighborhood was annexed into Yuba City, Quadriga facilitated the development of a new park in the annexed area. The City identified three prospective sites for a park with the goal of creating a space that serves both the residents of the historically under-served Tierra Buena area as well as greater Yuba City.
Once the City considered the community feedback and made a site selection, Quadriga prepared a master plan that incorporated many of the amenities desired by the community.
Quadriga is currently preparing construction documents which include two phases of development. Funding has been secured for phase 1 development. With help from Quadriga in preparing grant documents, the City is in the process of securing funding for phase 2 development.
Roseville, CA
Quadriga assisted the City of Roseville in Master Planning for a 5.2-acre neighborhood park within the Westpark community. The park includes a walking trail, picnic area, a 5-12 age-group play area and a basketball half-court. A central lawn area, designed to accommodate soccer practice, drains to the southern portion of the site. Bioswales, planted with a native hydroseed, form gentle depressions in which stormwater can infiltrate. Grading and drainage were designed to omit drainage infrastructure within the park.
A bike trail forms the southern border of the park. Beyond the trail exists preserved open space running along a branch of the Antelope Creek. Trees and low water use shrubs and ground covers selected for the park plant palette complement the adjacent landscape.
Following the master planning effort, Quadriga produced construction documents for R.G. Phillips Park.
Santa Rosa, CA
Not your average storage facility, this 95,000 sf building nestles into a site home to native heritage oaks and border by Santa Rosa Creek. Our goal was to provide thoughtful site planning assistance and to honor the natural systems on site as much as possible. Luckily the Owner was supportive of the team’s efforts and the resulting building and landscape resemble a nature preserve rather than a storage facility. Pavement is minimal, trees are large and the building is multi story and faced with ample glass - a very welcome site from the street.
Santa Rosa, CA
The Midtown 4th Community Outreach Campaign is a pro bono effort Quadriga is pursuing, with local design professionals and business owners, to improve the section of 4th Street between Brookwood Ave and Farmers Lane in Santa Rosa, an area we have lovingly dubbed "Midtown 4th." As design professionals we hope to help empower the local community to make 4th Street a better place to walk, bike, drive and patron.
Oakland, CA
Gallot Lofts is a 41 unit multifamily, urban-infill housing project situated within Oakland’s vibrant Jingletown District, near the Fruitvale BART station. The units frame a large, on-podium, communal courtyard filled with shade tolerant plantings, with weaving paths and seating areas. Large, raised planters filled with colorful vines engage the building’s architectural ‘fins’ that echo the neighborhoods colorful palette of diverse landscape arrangements and murals. Likewise, storm water planters collect and treat all rooftop runoff, and drought tolerant plantings fill the common areas and streetscape frontage unit.
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.

West Sacramento, CA
Riveredge is a mixed use housing project located along the Sacramento River. Walking distance from Sacramento’s cultural epicenters, including: Raley Field, Tower Bridge, Capitol Mall, and Crocker Art Museum, to name a few, the River Edge project holds the unique opportunity to draw and re-connect residents and the regional community to the river. Currently, properties along the river front do little to engage the river. The master plan for River Edge reconceives the edge of the river as a lively and articulated edge that supports a range of programming and recreational amenities. First of its kind in the region, Quadriga have proposed an urban beach along the River Walk Trail to re-engage the community with the river. The urban beach is a place to play in the sand, lounge under sun umbrellas, soak up river views, work out, and engage with the community in a new way that is embedded into the city fabric. The master plan also speaks to the historical inland sand dunes that once existed in our Delta and sand bar island that once emerged during low tide at the mouth of the American River. In addition to the beach, the edge includes outdoor gym and educational gardens. Quadriga crafted the master plan, including private interior courts, streetscapes, and recreational amenities with the public right of way.

Sacramento, CA
Quadriga worked with the developers of The Mill at Broadway community to create a comprehensive master plan for an urban infill site located near downtown Sacramento, CA. The plan explores overall connectivity within the development and delves into the planning of four specific open spaces: The Park, The Farm, The Farm Walk and Setzer Run. By maintaining a flexible approach and working closely with the Client, Quadriga can respond to development design changes as they occur and ensure that the master plan continues to provide the best possible solutions for the community.
One of the main focuses of the master plan is the development of a neighborhood park. The allotted area is small, under 4 acres, and is centered around an existing building. The park’s prospective user population reflects The Mill at Broadway Community and is largely made up of adults. The master plan includes several flexible, multi-functional spaces that are unique to the context of this site.
Sacramento, CA
Quadriga worked with the developers of The Mill at Broadway to create a comprehensive master plan for an urban infill site located near downtown Sacramento, CA. Floyd Farm and Community Garden form a 2-acre area within The Mill at Broadway community.
Floyd Farm is an urban farm programmed as a production garden and educational hub for members of The Mill community as well as youth and adults throughout the Sacramento region. The Farm will be operated by an educational non-profit group who will host nutrition programs in which people can learn how to grow and prepare nutritious food.
The Community Garden is a 0.4-acre area within the overall farm that will be operated by the Sacramento Youth, Parks, & Community Enrichment department. Like other city community gardens, the public will be able to apply for and operate a plot. With 73 plots, 4 ADA plots, and an orchard area, The Mill at Broadway Community Garden will be the City’s largest.
As of spring 2020, construction has begun.
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.
East Bay, CA
Designed as mitigation for the Bay Bridge Project, the San Pablo Avenue Green Stormwater Spine consists of eight sites that collectively treat more than six acres of urban runoff. Quadriga, as part of the project team, collaborated with multiple city jurisdictions and CALTRANS to introduce a green stormwater system that will function within the existing infrastructure framework. The system includes stormwater planters and rain gardens which have been verified by the EPA in their effectiveness to remove pollutants from stormwater. Quadriga has been involved throughout the conceptual design and construction administration process. The project is on track to be Bay Friendly certified and is expected to be complete by Spring 2017.
