Pendleton Westgate Gateway

This project implemented a high-priority project identified in the Pendleton Court Avenue/River Parkway Master Plan prepared by Greenworks.

The goal of this project was to create a meaningful gateway at the Westgate entrance to downtown Pendleton. The previous conditions at the Westgate Intersection were a confusion of unsafe vehicle traffic circulation, a multitude of cluttered overhaul utilities and barren landscape slants. The City of Pendleton and ODOT reconfigured the intersection to provide safer traffic movements and reduced utility pole/lightpole clutter to create a simpler and safer intersection solution.

GreenWorks worked with the proposed intersection improvements to enhance the visual gateway aspect of the project. GreenWorks designed landscape and interpretive improvements and displayed decorative wall features to create a strong sense of arrival at this intersection. The decorative wall design was reputed at the Riverfront Park location to help tie together corridor improvements

Fernhill Wetland Master Planning and Design

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.

Lake Oswego 2nd Street Green Street

This green street project is located in the heart of downtown Lake Oswego. With the slight narrowing of the curb to curb width of the street, the City transformed the street into a beautiful modern streetscape within the core of the downtown business district. Widened sidewalks, street lights, benches, driveways, street trees, and unique stormwater planters were all delicately knitted together by the design team to deliver a streetscape project that benefits the surrounding business community while protecting the urban watershed.

Lake Oswego Demonstration Street Project

GreenWorks closely collaborated with an engineer and urban designer to develop a prototype street reconstruction plan that emphasized a pedestrian friendly environment. Design solutions included narrowing of lane width, replacing left turn lane with landscape median, addition of a rich variety of paving materials in pedestrian zones and placement of street furniture, ornamental street lights, street trees, and annual color accent planting. Our specific responsibilities included final design and specifying of cobblestone paving in crosswalks, pre-cast concrete pavers in parking zone, patterned concrete in pedestrian and furniture zones, as well as landscaping improvements.

Chambers Creek Wastewater Treatment Facility

As part of ongoing development at the 930-acre Chambers Creek Properties, GreenWorks developed schematic design and construction documents for long-term sustainable stormwater strategies integrated with perimeter landscape buffers for the existing Chambers Creek Wastewater Treatment Plant (CCWTP) wastewater treatment plant and planned expansions. Working closely with Pierce County staff, Brown & Caldwell engineers, and Michael Willis Architects, GreenWorks developed the landscape buffer concept to visually and physically screen the treatment plant.

The buffer serves to blend the treatment plant area harmoniously with the dramatic landscape of south Puget Sound, surrounding land uses and future development on and off the plant site. The design incorporates stormwater management facilities that treat plant runoff, provide new recreation trails that connect with existing trail networks, and improve wildlife habitat. The buffer must also accommodate support facilities for bus traffic and large crowds attending the 2010 PGA US Amateur’s Open and the 2015 US Open to be held on the adjacent Chambers Creek Golf Course. In addition to the perimeter buffer, GreenWorks is working on the redevelopment of the plant entrance to improve visibility and enhance circulation.

Headwaters at Tryon Creek

GreenWorks provided landscape architecture services in master planning a new 2.8 acre mixed residential development near the headwaters of Tryon Creek. The project includes a variety of residential types including elderly housing, town homes, and a Portland Development Commission (PDC) built low-income apartment building. All of the new residential developments, along with an existing apartment building, were designed to be integrated with the daylighting of a tributary of Tryon Creek. The development was coordinated with many local agencies (PDC, Portland Department of Transportation, Portland Parks and Recreation Bureau, and Bureau of Environmental Services) to extend the daylighting project from the headwaters of the tributary in a park adjacent to the site, through the site and adjacent neighborhood to Tryon Creek. The goal of the developer and the design team was to incorporate the buildings, parking, plazas, bridges, and other site elements into a cohesive sustainable site development that takes full advantage of this daylighting opportunity. GreenWorks services include schematic design, design development, construction documentation, and services during construction. This project is certified LEED Silver.

Lane Community College Health & Wellness Center

GreenWorks provided site design for the new Health and Wellness Building and surrounding open space on the Lane Community College campus in Eugene, Oregon. The team was tasked with creating a dramatic, attractive and sustainable environment for the new academic building’s site. The resulting design demonstrates responsible environmental practices and creates an active “living” classroom for educational opportunities. Rainwater is captured and conveyed into bioswales, translating health and wellness to the physical landscape. The Health and Wellness Facility is located at a major entrance point to campus, making clear circulation and a sense of arrival essential to the design concept. The design connects the multiple levels and pathways surrounding the Health and Wellness Center to the rest of the campus, creating a clear entry sequence that maintains accessibility for all. The result is activated exterior spaces that engage and connect.

Expo Center Stormwater Green Wall

The Portland Expo Center Stormwater Green Wall is the first of its kind in the United States. It integrates sustainability, art, and science for managing stormwater runoff.

Designed by a team led by GreenWorks, PC, it’s an innovative and unique project representing 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 Portland Expo Center Stormwater Green Wall, designed with many partners including Oregon Metro, 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. 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 Center’s logo and brand. This project was constructed in 2014.

“There’s an educational component going on here… We want to explain how this structure is more than architecture. It’s connected to good, sustainable practices and mitigates the Expo’s footprint.” - Lydia Neill, Oregon Metro

A female mallard duck was recently photographed enjoying the Wall’s lush vegetation. Since opening in 2014, the Stormwater Green Wall has flourished. After a few winters that have broken rainfall records in the Portland Metro area, the ferns, star jasmine, sedge, and other plants are thriving. We are delighted to learn that besides processing stormwater, it provides urban wildlife habitat too!

Sandpoint Downtown Reversion

Blue Heron Mill Site Visioning

GreenWorks conducted a preliminary investigation on the Blue Heron Paper Mill site, which included research on the site’s history, river access investigations, preliminary concepts, and magnitude of cost estimate. The purpose of this work was to gain a better understanding of the potential to provide public river access, as well as for other recreational, interpretive, open space amenities and economic redevelopment features.  Celebration of the Willamette Falls and its cultural significance over the decades is also an integral component of the concept.  GreenWorks built off this initial effort to develop a vision for the site that is inspired by the 3 main eras evident on the site—the Natural Era, Cultural Era, and Industrial Era—all interweaving to become an expression of a new era of sustainability for Oregon City. New initiatives will target public open space, economic redevelopment, interpretive facilities, Falls overlooks, and riverbank restoration.

Russellville Commons

Russellville Commons, located adjacent to the TriMet MAX stop at E Burnside and SE 102nd Avenue, is a three- to four-story assisted living facility with group care units for Alzheimer patients built atop an underground parking garage. It is one of the first multi-family developments in Portland’s Gateway District, part of the 1996 Outer Southeast Communtiy Plan’s densification initiative.

GreenWorks is designing streetscape improvements for Phase III, as well as an interior courtyard space that includes a memory care courtyard and a fountain. Significant streetscape elements include flow through planters that manage the building’s roof runoff along E Burnside and SE Ankeny Streets, and an entry plaza with special paving along and across SE 103rd Avenue extending to the Phase II section of the project. The interior courtyard space includes sculptural walls that provide a variety of spaces for individuals and for group interaction, as well as a tree-covered outdoor dining area. A circular vegetated swale handles courtyard stormwater runoff and provides a central landscape feature that echoes notions of healing and tranquility for the building’s residents.

Mt. Scott Creek Oak Bluff Reach

GreenWorks, with subconsultant, Inter-fluve Inc. are working with Clackamas County WES on the Mt. Scott Creek Oak Buff Reach project to enhance in-stream habitat and stabilize cut banks, reduce peak flows and improve water quality, control invasive species and improve public assess and opportunities for environmental education. The team is currently designing different projects along Mt Scott Creek and conducting a no rise analysis as well as a cost benefit analysis to determine the overall project design.

Red Electric Trail

Together with a team of engineers, GreenWorks is providing design, environmental, right of way, and construction engineering services for ODOT. The project includes the design and construction of two segments of a trail that will be a 12-15’ wide, shared pedestrian and bicycle bridge crossing over a ravine in the public right of way between SW Bertha and SW Capitol Highway.

When complete, the Red Electric Regional Trail will provide an important multi-modal link to other pedestrian and bicycle facilities in Southwest Portland. This off-street trail will connect residential areas with the Hillsdale Town Center and other destinations in SW Portland, and provide a safe alternative to bicycling and walking on SW Beaverton-Hillsdale Highway and SW Capitol Highway.

City of Dallas Streetscape

The City of Dallas Streetscape Design Concepts and Toolkit provides an adaptable strategy for downtown Dallas to take advantage of existing opportunities and assets to improve and expand the quality of the central district and streetscape conditions. The aim is to re-establish the central area as a pedestrian-friendly, safe, and economically viable district that is reflective of the unique identity of the residents of Dallas. GreenWorks worked with a diverse group of stakeholder from the City of Dallas and the Urban Renewal Agency to develop consensus on a design concept, materials toolkit, and street tree selection criteria which will guide the downtown core as well as provide additional guidance for future projects. Specific activities included ODOT coordination, visualization, and development and refinement of multiple concepts. The City is currently going forward with an initial pilot project, and is developing funding sources for the initial three-block catalyst project to be constructed in 2011.

Mt. Hood Campus Creek Clean Water Retrofit

Estacada Library

GreenWorks engaged with the design team and Estacada residents to develop a new two acre library site that serves as a community hub. The new library took advantage of its location on a former mill pond that was becoming a new community public open space. Our team designed the site to: take advantage of views along the pond edge; connect to a public trail system and parkland; create outdoor courtyard space for library users; and treat and infiltrate stormwater using ecological principles. Stormwater collection and conveyance features were designed to be visible to the public and help to create identity. The site design incorporated native plant communities in the overall planting design.

Tigard Library

GreenWorks, in collaboration with SRG Architecture, was hired by the City of Tigard to site the city’s new library and community center on one of the most pristine and pastoral pieces of property remaining in the tri-county area. The property is wedged between an existing state highway, which will be widened in coordination with this project, and a virtually untouched segment of Fanno Creek. As part of the overall site design, we were responsible for siting the building, parking, adjacent plazas, and stormwater facilities in such a manner as to protect the existing landscape forms and several significant trees. We were challenged with integrating the significant site characteristics and the proposed buildings and support facilities together into a cohesive, sustainable, and attractive development.

Sustainability issues included: preservation of existing landforms/ enhancement of views, preservation of existing vegetation, creation of Fanno Creek riparian buffers, provision of stormwater infiltration/ treatment facilities, reduction of effective impervious surfacing, and design of ecological landscaping.

Lake Oswego and Tigard Water Treatment Plant

The Lake Oswego – Tigard Water Treatment Plant is being expanded  to serve future demands forecasted for the Lake Oswego and Tigard service areas. GreenWorks provided landscape design for stormwater management and to address visual impacts for components of the plant that could be seen in residential areas as well as providing amenities for neighborhood use. Amenities included a neighborhood trail, public open space for neighborhood use,  and native woodland enhancement. GreenWorks  actively met with the adjacent neighbors to hear their concerns about the project and with the broader community at workshops to describe landscape / site design elements for public comment.

Milwaukie Public Safety Facility

GreenWorks designed a planting plan for this facility to provide an attractive, low maintenance setting, and to create a pocket park for neighborhood enjoyment in a redeveloping area of Milwaukie. The plan also included hardscape layout / entry courtyard and overall landscape treatment. GreenWorks prepared concept plans for public review and construction drawings for planting and irrigation improvements.
