Mirror Pond Bank and Trail Improvements

GreenWorks with sub-consultants, Inter-fluve, Inc and HDR, are working with Bend Park and Recreation District (District) on the Mirror Pond Trail and Bank Improvement Project. In 2013, GreenWorks worked on a Visioning Plan for Mirror Pond from the Galveston Bridge downstream to the Portland Bridge including both sides of the river. In early 2017, the GreenWorks team moved forward with design to repair failing systems along the river, connect and extend the Deschutes River Trail, address ADA, mobility and access and create and enhance habitat.

The project site is in the heart of downtown Bend and spans from Drake Park through private land to Pacific Park along the right bank of the Mirror Pond and the Deschutes River. Drake Park is a popular downtown community gathering place and is highly used by floaters, runners, cyclists, pedestrians and others. There are user conflicts between floaters and pedestrians and cyclists and pedestrians.  Drake Park, on the upstream end, is also the hop-out site to take the River Shuttle. Due to the high traffic, GreenWorks is designing a large waiting plaza with restrooms and benches across from the shuttle parking. In addition, the team is working to expand and enhance the beach, making this location a more enjoyable and safe location for users. 


There are sections along Drake Park that preclude cyclists, strollers and wheel chairs as well as areas where there are user conflicts between pedestrians and cyclists. The GreenWorks team has creatively designed an accessible route to connect the Deschutes River Trail from Pioneer Park downstream through Pacific Park where it meanders on back surface streets until it reaches a new boardwalk at Newport Bridge. The boardwalk will span from Newport Bridge along the edge of Mirror Pond to the plaza in the center of Drake Park. Once users get to the plaza, there will be spilt in the trail, cyclists will traverse toward the road and meet back with the original alignment of the DRT and pedestrians will along the water edge. 


Banks along the river are eroding and there is constant maintenance. The GreenWorks team along with stakeholders worked together to determine that the banks were not to be armored with rip rap but where to address erosion as well as create habitat. The solution involves the removal of the concrete cap on top of the wall, deconstruction of banks and reuse the rock in place, adding large wood a few strategic locations as well as riparian plantings. In two sections of the project where the large wood will be located, split rail fence will be installed to deter the trampling of vegetation that will allow for the vegetation to remain in place for the enhancement and creation of habitat.  


Currently, GreenWorks is beginning to move the design from 30% to 100% and eventually through construction. 

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.

GreenWorks is part of a multi-disciplinary team that renovated this regional wastewater treatment facility in historic downtown Oak Harbor, Washington. Situated in Windjammer Park, on the shores of Oak Harbor, the facility takes advantage of technological updates to modernize the facility, integrate it with the surrounding environment, and reduce its visual and olfactory impacts.  

the facility takes advantage of technological updates to modernize the facility, integrate it with the surrounding environment, and reduce its visual and olfactory impacts.  

Routes for cars and people on either side of the facility provide easy access from downtown Oak Harbor to Windjammer Park and the waterfront. The site plan requires the creation of strong physical and visual links along these axes. The planting and hardscape reflect the coastal setting, with the inclusion of rolling dunes planted with coastal grasses and perimeter sidewalks, emulating local wooden docks. Parts of the facility are exposed to the public, offering opportunities for interpretation along the two main thoroughfares.

Washougal Town Square

Located at the City Center, this mixed use office/retail project was envisioned to be a catalyst for town center redevelopment. GreenWorks designed the site improvements to reinforce pedestrian and visual connections to the urban fabric and to the Columbia River Gorge area as a demonstration project. GreenWorks implemented goals for a sustainable development model by creatively designing stormwater solutions, rainwater harvesting, a central courtyard, and native plantings in an urban context for the one block development. GreenWorks used 3-D modeling to enable the design team, developer and local staff to visualize design solutions. This project is one of the 10 LEED-ND pilot projects by the USGBC for the nation.

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.

Chambers Creek Wastewater Treatment Facility

DSC_0996.JPG

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.

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.

Blue Heron Mill Site

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.

Eastbank Crescent Habitat Restoration

The Eastbank Crescent Project is located between the Hawthorne and Marquam bridges on the eastbank of the Willamette River. The purpose of the project is to create a recreational destination and a fish and wildlife habitat refuge.  The project is a collaborative effort between City of Portland’s Bureau of Planning and Sustainability, Bureau of Environmental Services (BES), Portland Development Commission, Portland Parks and Recreation, GreenWorks, Mayer-Reed, and Flowing Solutions. Based on existing conditions analysis, constraints and opportunities, three concepts were developed including maximizing recreation, maximizing habitat and a hybrid of the two.  GreenWorks, with sub consultant, Inter-fluve Inc., was task by BES to enhance in-water nearshore habitat for ESA-listed fish, restore riparian and upland habitat for birds and wildlife, and incorporate river habitat education opportunities. An array of habitat treatments were considered including laying back the riverbank to create more habitat by vegetating with native plants, undulating the shallow water area with alcoves or backchannels to enhance fish habitat and creating viewpoints and access for education.  The concepts were presented to stakeholders and the public and a preferred alternative will be developed based on public input.

Mirror Pond Visioning Project

GreenWorks has started consulting work with Bend Parks and Recreation District on alternatives that will provide four different solutions for the community to consider for the iconic Mirror Pond on the Deschutes River in Bend, Oregon. Each option, ranging from taking out a dam to dredging or something in between, will illustrate the visual impact, cost estimates, regulatory requirements, challenges and opportunities.

Clackamas Head Start Facilities

GreenWorks developed a Site Master Plan for the new Head Start Facilities in Clackamas County. Through creative treatment and handling of stormwater the Playground and Outdoor Courtyard Classroom on site create learning opportunities related to water and the environment. The Playground features a variety of outdoor activities for active play and discovery, including a play structure, tricycle track, and fossil themed sand box. The nature trail, along with raised garden beds, provides lessons in science, observation and stewardship. The Outdoor Classroom, or courtyard, focuses on connecting students with the physical properties of the water cycle; falling rain, run off as stormwater, evaporation, and transpiration. The courtyard is a place of dynamic activity highly influenced by the environment, the sun and the rain, and easily visible to students from inside the building.
