Greenworks is honored to be working with the City of Independence to implement the vision set forth in the Open Space Master Plan completed in 2015. The current work on Independence Landing improves a key piece of public waterfront located immediately south of Riverview Park, the flagship of the Independence park system. Designed in tandem with the with the large waterfront re-development on the old Valley Concrete Site, Independence Landing  is one piece in a larger orchestrated effort to revitalize downtown Independence and support commercial growth.

Conceived of a an extension of Riverview Park, Independence landing will offer users a number of passive recreation opportunities. Included in the plan are a waterfront multi-use trail with a river overlook, a shaded patio and lawn space able to accommodate flexible programming, a sizeable restoration planting area braided by soft surface trails and a grove of shade trees in which the user can find informal, private seating areas. This implementation of the Open Space Master Plan sets the stage for the continued expansion of improved public waterfront southward along the Willamette River and strengthens the downtown, pedestrian connections to the waterfront.

The success of this project has been a measure of how well the project team has worked together. Shawn Irvine and David Clyne with the City of Independence and Steve Ward with Westech Engineering have been instrumental in guiding the design process, representing the diverse community of Independence and streamlining the construction of this exciting new park space.

Spring Park

North Clackamas Parks and Recreation District and the City of Milwaukie partnered to improve in-stream and riparian areas and a new trail access at Spring Park in Milwaukie, Oregon. As the project Landscape Architect, GreenWorks analyzed the topography and sensitive areas to find the ideal location for a soft surface trail, boardwalk, and overlook that would improve access and provide excellent user experience within the restored riparian landscape.


Canemah Bluff

Canemah Bluff is a 300-acre natural area owned and maintained by Metro within Oregon City. GreenWorks worked with Metro to develop public access to the sensitive oak savannah and woodland, which included improving hiking & walking trails, new boardwalk, foot-bridge, and scenic overlook.

During the Public Involvement phase, GreenWorks helped engage the community and gain support from a highly motivated neighborhood group. We prepared a design that reflected both Metro’s and the neighborhood’s goals for minimal impact to natural resources, yet provided for a safe place for users to enjoy the natural area. GreenWorks produced graphic presentation materials that helped convey the design so both the client and community could fully understand and appreciate what the end product would look like once built.


Ridgewood View Park Reservoir

GreenWorks aided Tualatin Valley Water District (TVWD) in replacing an outdated reservoir with a new one adjacent to Ridgewood View Park in Beaverton. The new water project required extensive piping and construction staging on the Tualatin Hills Parks and Recreation District (THPRD) park site. In turn, TVWD needed to upgrade the amenities in Ridgewood View. GreenWork’s proposed new park elements including open lawn, paths, parking, picnic shelters, access to natural areas, playgrounds, and a bocce ball and tennis court on top of the reservoir. Innovative elements for the project included terraced rain gardens that treat and convey stormwater from the roof of the reservoir. The park’s new rain gardens help screen the 15’ wall of the reservoir in the park and provide an educational resource for TVWD, THPRD, and the residents of the neighborhood.

Gresham Center for the Arts Plaza

 GreenWorks designed the new Center for the Arts Plaza in downtown Gresham for the city and its non-profit partners. The plaza is the new “living room” for Gresham and features a dramatic integration of the arts using light, water and sound. Key features include “art pillars” dedicated to literature, music, performance and fine art. Additionally, an interactive public fountain, large gathering space for concerts and dynamic lighting effects enhance nighttime activity. The plaza spills out into a “festival street” along Third Street and is host to many community events such as farmer’s markets, civic ceremonies and patrons of the Center for the Arts.


Fernhill Wetland Mitigation & Master Plan

Fernhill Wetlands is part of a 748 acre parcel near Forest Grove, OR, owned by Clean Water Services and managed in partnership with Forest Grove.  The site, located within the Tualatin River Watershed, consists of agricultural fields, wastewater treatment and other public utility facilities, and several pristine wetlands which are open to the public and draw birders from far and wide who come to observe the many rare migratory bird species that stop at the wetlands during their journey.
With future plans to integrate the wetlands into the wastewater treatment process as part of a natural and sustainable cleansing and cooling approach that preserves the site’s ecological and recreational significance, Clean Water Services commissioned GreenWorks as consultants who bring extensive experience in constructed wetland and green infrastructure design.  In collaboration with CWS, GreenWorks developed a master plan vision for the site which included an overall site layout consisting of treatment wetlands, roads, trails, overlooks and other public spaces; a graphic representation of the water circulation path from wastewater treatment facility all the way to the Tualatin River; accompanied by a collection of artistic photorealistic renderings from various vantage points, which will collectively be used to clearly convey design intent throughout future project phases.

The Unified Sewerage Agency contracted with GreenWorks as part of a team of engineers, biologists, and hydrologists, to develop wetland development concepts for a large-scale wetland mitigation bank, along Gales Creek in Forest Grove. The concept plan recommendations included the establishment of ash forest wetland, emergent marsh and scrub-shrub wetland, wet meadows, and oak woodland upland buffers.

Zidell Green Infrastructure

The 33-acre Zidell Yards site offers the first holistic, comprehensive opportunity in Portland, Oregon to identify solutions for applying green infrastructure to manage stormwater on one of the largest brownfield remediation and redevelopment sites in Portland.  The goal of this effort was to develop a range of comprehensive green infrastructure scenarios consistent with the constraints of a recently remediated brownfield that can be implemented within the framework of a 15- to 20-year development master plan.

Expo Center Stormwater Green Wall

The new stormwater green wall recently installed at Portland’s Expo Center is the first of its kind in the United States to integrate sustainability, art, and science for managing stormwater runoff.

The Portland EXPO Center Stormwater Green Wall, designed by a team led by GreenWorks, PC, is an innovative and unique project that represents the next step in creative stormwater management solutions, by taking roof-runoff and routing it through a series of vegetated planters mounted to a vertical wall structure. The Expo Center Stormwater Green Wall isn’t a traditional bioswale or garden. Instead, it effectively uses the available vertical square footage of the existing building to provide stormwater filtration for the 9,400 square foot roof.

Standing 30-feet tall and 60-feet long, the free-standing, artistic structure is made of steel and aluminum and is adorned with soil and vegetation native to Oregon, particularly the Columbia River Gorge. Because of the stormwater wall’s prominent location, it was important that the design fit within the context of the existing site and complement the existing postmodern style of architecture. This was accomplished by giving particular attention to forms and materials that were used. The form of the stormwater channels relate to forms evident on the existing building and the hexagons provide a decorative element that ties in subtly to the EXPO’s logo and branding effort. This project was constructed in 2014.


Kenton Denver Avenue

Portland’s first green main street, the Denver Avenue Green Street extends along the four-block historic Kenton business district in north Portland. The initial phase of the streetscape design developed an overall concept for the street section, including the widening of sidewalks, addition of bike lanes, and the restructuring of existing parking, drive lanes and medians. The design developed through input from a Citizen Advisory Committee, a Technical Advisory Committee, and with extensive public involvement at open house meetings. GreenWorks, as part of a multi-disciplinary team, prepared an overall street layout for the corridor that defined paving patterns, materials, street trees, site furniture, ornamental light fixtures, and the design of gateways at either end of the corridor. An important component was the integration of green street stormwater solutions within the right-of-way. This project was completed on time and on budget.

Our initial design work moved successfully into a constructed streetscape project in 2010 with GreenWorks providing construction documentation led by the Portland Bureau of Transportation. As a main street and ODOT-designated freight route, we successfully integrated sustainable design with main street design to create a vibrant streetscape. Long suffering from a high storefront vacancy rate, the Kenton downtown now has experienced a boom in new businesses and its local economy.


BES Johnson Creek Oxbow Restoration

In November of 2014 GreenWorks began a site assessment and preliminary design for the Johnson Creek Oxbow Enhancement Project. The central feature of the site is the namesake “Oxbow” meander, which is bounded on the south by a bypass channel that truncates the oxbow creating an island. The by-pass channel was constructed by the Works Progress Administration (WPA) in the 1930’s and included armoring the creek bed and banks, and creating a fish ladder in the oxbow to maintain fish passage. The goal of the WPA work was to convey flood flows efficiently downstream. It resulted in a confined channel, which is hydrologically disconnected from adjacent floodplains and wetlands, and exacerbates flooding. GreenWorks was charged with providing design strategies for improving floodplain hydrology, riparian and in-stream habitat, and local flood impacts.
To support these goals, GreenWorks held a one day charrette, which included members from BES, ESA-Vigil Argimis, and KPFF to discuss and recommend a variety of design strategies for improving the inherent conditions found within the Johnson Creek Oxbow. Recommendations were collected and vetted amongst the consultants and further discussed with BES to determine a set of design alternatives for specific sites within the project area. Project sites were mapped, along with support graphics and images, and cost-estimates, to BES in a comprehensive Pre-Design report, thus allowing BES to prioritize future improvement projects for the Johnson Creek Oxbow area.


BES Flyway Wetlands Enhancement

GreenWorks provided landscape architecture services for Portland’s Bureau of Environmental Services Flyway Wetland property located between the Columbia Slough and the Columbia River near the Portland airport. GreenWorks led a team to provide several wetland restoration concepts and a wetland delineation report. GreenWorks headed several workshops with the consultant and team to develop the preferred concepts based on goals for the project including: water quality improvement; vegetation and habitat restoration; wetland hydrology improvement; and floodplain wetland hydrology improvements. Wetland and Stream Delineation Reports and Wetland Restoration Concepts were created for internal analysis related to bureau’s goals for restoring the site and their overarching restoration goals for bureau’s environmental group.

BES Columbia Slough Stormwater Retrofit Inventory

In January 2010, GreenWorks and BES staff conducted intensive field work locating and documenting potential locations for stormwater facilities throughout the Columbia Slough Watershed in North Portland. The Columbia Slough has been designated a high priority area by the City of Portland for improving watershed health and reducing pollutants. The project team focused on four target areas where green street facilities would maximize stormwater quality treatment and capture contaminated sediment before being discharged into the Slough. Each potential green street facility was ranked based on its potential performance, feasibility, and cost. GreenWorks assisted BES in project prioritization and provided an overall ranking using Geographic Information Systems (GIS). Over 150 potential green street facilities were identified, which would potentially result in stormwater treatment from over 35 acres of impermeable surfaces.

Empire Boulevard

The City of Coos Bay received federal funding to install bike lanes, landscape strips, and sidewalks to Empire Boulevard between Newmark Avenue and Wisconsin Avenue to provide alternative transportation opportunities along this heavily traveled corridor.

Improvements include widening the existing two-lane road to make room for on-street parking and bike lanes, installing curb, gutter, landscape strips with street trees, and sidewalk on both sides of the road. Stormwater / water quality facilities are constructed to manage stormwater on-site, converting Empire Boulevard into a ‘green street’. Other project elements include interpretive overlooks with site furniture, illumination, signing, striping, and numerous driveway connections.
