Quadriga is providing design and construction document services for the renovation of Sutter’s Emergency Department Expansion new landscape and plazas in Roseville, California. The focus of the design studies will be to provide healing and contemplation gardens and plazas that incorporate existing drainage features and water use concerns while providing a unique landscape identity for the site that responds to the natural oak woodland surroundings. The concept includes a linear plaza zone, terminal plaza zone, multi-level interior courtyards, elements of a healing garden and contemplation garden, extensive bio-swale features, low water use and native plantings, and a high efficiency irrigation system.
Santa Rosa, CA
The #MIDTOWN4TH community outreach campaign is a YIMBY (Yes In My Backyard) 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.
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.
Town of Windsor, CA
Russian River Brewing Facility is a fully operational brewery and customer experience destination. Located in an industrial zone outside of the Town core, the landscape architectural approach echoes that of the architectural itinerary. An edible garden, hop growing and fermentation viewing areas honor the brains of the building – the functioning brewery; bike parking, queuing, outdoor welcome and dining areas reflect the owner’s commitment to hospitality; use of existing and new native oaks paired with enhanced wetland areas and storm water retention reinforce responsible sustainability practices.
West Sacramento, CA
River Edge 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.
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.
Quadriga worked with the developers of the Mill at Broadway community to create a comprehensive visioning plan that explores the overall connectivity of the development as well as the integration and function of four crucial site elements: the park, the farm, the farm walk, and Setzer run. Expanding on this initial visioning document, Quadriga is currently developing a master plan for the site as a whole as well as for each of the main program areas. By maintaining a flexible approach and working closely with the Client we are able to respond to development design changes as they occur, ensuring that the master plan continues to provide the best possible solutions for the various spaces that are part of the tight urban infill site.
One of the main focuses of the master plan is the neighborhood park. It is a unique opportunity in that it is a small area (under 4 acres) centered around an existing building and has a prospective user population that is largely made up of adults. As a result the master plan prescribes a number of flexible, multi-functional spaces that are unique to the context of this particular site.
The 16th Street Light Rail Station rests at the nexus of Sacramento’s Midtown District. Steps away, the R Street is a burgeoning street with bustling nightlife and cultural offerings. The 16th Street Light Rail Station has the highest traffic of any stop in the system, yet the station is perceived as unsafe, uncomfortable for both riders and passerbys, and poorly maintained. After several site visits it is clear that there is inadequate amount of maintenance, seating and lighting and unlawful activities occurring regularly, including public urination and unlicensed vending.
For the purposes of this conceptual re-design, it is important to focus on improvements that improve the aesthetic/physical environment of the station in order to communicate a sense of community and cultural richness in a contemporary way. In addition to that, the improvements must also address the underlying conditions in a way that is both functional and resourceful. The master plan proposal includes unified paving systems, vertical seating, shipping container kiosks, murals and custom light fixtures.
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 circulation system is designed to function as a campus thoroughfare yet maintain primary 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, yet enclosed, gathering areas for students to study and socialize. The smaller
two courtyards provide 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. Selected shrub and grass plantings, a palette of both native and adapted species, evoke the aesthetic of the nearby California foothills. Trees are placed to help frame preferred views, screen undesirable views and abate strong delta winds.
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.
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.
In honor of Margrit Mondavi’s love and passion for art, the Margrit Mondavi Art Garden seeks to inspire people to consider life’s beauty. A former parking area, the space has been transformed into a mosaic of diverse and colorful flower beds mimicking floral paintings drawn by Margrit Mondavi herself. The flowers serve as the backdrop for works of art such as William Tucker’s Leda, John Connell’s Earth-Touching Buddha, and Dan Snyder’s The Restoration of Hope II. Curvilinear, low garden walls frame the garden and invite visitors to pause, enjoy and contemplate. Quadriga worked collaboratively with campus landscape architecture staff to develop the design and construction documents. Adjacent to the newly constructed Manetti Shrem Art, the materials and design of the garden compliment the museum and showcase’s the university Fine Arts collection.
West Sacramento, CA
The Moderns at Eames Walk is part of a burgeoning district in West Sacramento, CA along the Sacramento River. The 21 single-family homes are positioned around a shared “walk” that serves as a core common space for the neighborhood block. A central walk – Eames Walk, moves residents through a grove of shade and flowering trees and drought adapted plantings. The proposal seeks to integrate and blend outdoor and indoor spaces. A series of boardwalks bridge residents from the Eames Walk to individual units. Individual private courtyards are framed by low concrete walls and specialty paving and are designed for flexible space for outdoor dining, gardening and lounging.
Architect: Studio Skaggs Kennedy
PORTAL is a temporary installation designed to bring life to dormant spaces within Sacramento’s urban fabric and engage the local community through programming that celebrates the region. Open to the community for a one-month period, PORTAL anchored over twenty events, supported by over twenty-five local businesses and organizations. Events included community focused lectures, author talks, performance showcases, pop-up shops, yoga classes, a drought tolerant planting exhibit, a movie night, and a silent disco. The installation concluded at TBD Fest, Sacramento’s 3-day music and arts festival. In addition to community activation through programing, PORTAL also promotes social media engagement through the use of the custom hashtag, #portalsac. PORTAL photos, stories, and ideas were posted by the community via Twitter, Instagram, and Facebook, with each post triggering the installation to change the color of its LED lighting.
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.
Situated within the historic State Capitol Park and located directly across the street from the State Capitol entrance, this existing memorial is slated for embellishment. The original monument, a lone soldier known as “El Soldado”, was dedicated to honor the devotion, dedication, and sacrifice of California’s Latino Veterans to state and country. Quadriga was retained by the California Mexican American Veteran’s Beautification and Enhancement Committee to develop a design which will compliment and elevate 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.
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.
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.
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.
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. We were integral to the design including grading, planting and irrigation.
Working closely with the Audubon Society, the Audubon Area serves as a habitat for birds and bats, while providing users a peaceful and contemplative space within the greater context of Whitney Ranch’s Community Park. Winding paths framed by interpretive signage lead visitors through the Audubon, inviting visitors to pause and learn about California native plant species and encourage the use of water sensitive landscapes. Stacked bluestone walls support perimeter seating spaces for visitors to relax and enjoy the views of the garden and larger park.
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.
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.
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 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.
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.
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.
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.
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.
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.
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.
