Reed's Crossing Greenway Park

Reeds_View_00_Birdseye.jpg

Reed’s Crossing is a master planned community developed by Newland Communities. The community will be constructed over the next 15 years and will comprised of single and multi-family residential, commercial, mixed use and high-density residential development with associated roadways, utilities, stormwater facilities, trails and open space. Reed’s Crossing community is approximately 460 acres and it is part of the South Hillsboro Community Plan, Hillsboro, Oregon.

GreenWorks has been working collaboratively with Newland and project civil engineers to design the heart of the development— the 23-acre greenway. The greenway is comprised of approximately 12-acres of stormwater facilitates that will cleanse stormwater running off roads and rooftops of the new development. These stormwater treatment facilities will be seamlessly incorporated into the landscape and design of neighborhoods and civic spaces.

The greenway will link both the community internally and adjacent neighborhoods by the multimodal trail network traversing the site. The greenway will also support riparian habitat, passive and active recreation, and open space preservation. A variety of planting types are displayed throughout the greenway from wetland habitat to oak savannah and meadows.

Greenworks worked with Newland from concept through permitting and construction documentation. Throughout the process, Greenworks coordinated with nurseries to grow the 300,000 plugs that were planted in the stormwater facilities as well as all the shrubs and trees that will surround the stormwater facilities and the trails.

During construction, Newland Communities hired GreenWorks landscape construction manager full-time to oversee and coordinate the construction of the greenway, as well as the streetscape design.

River Island

River_Island_sm.jpg

Situated along the Clackamas River near Barton County Park, River Island is 240 acres of natural area that provides habitat for native species including endangered salmon and steelhead, native turtles and migratory birds. The main portion of the site in the middle of the river was a gravel mining operation until the 1996 flood, which greatly altered the natural area's landscape by breaching man-made levees and shortened the main channel of the Clackamas River. GreenWorks and Inter-Fluve worked with Metro to help create a vision and concepts for restoring natural channel processes and supporting multiple values including fish and wildlife habitat, riparian and upland forests, water quality and recreation.

 

GreenWorks assisted with public outreach and prepared presentation materials to easily convey complex engineering concepts into understandable, photo realistic graphics that help the public and stakeholders understand the opportunities and what the site could look like once it is restored. Conceptual design alternatives were created for restoration of riparian-forested wetlands at the gravel mine site as well as design and restoration of Goose Creek, reconnecting it to the Clackamas River mainstem for cool water rearing habitat for juvenile salmonids. Inter-Fluve is currently developing a site conservation plan and permit-level designs.

Willamette Riverbank Design Notebook

Hired by the City of Portland, GreenWorks led a team of biology, engineering, and erosion consultants to investigate existing bank conditions along the Willamette River in downtown Portland. The banks were inventoried by category and then color maps were created using ArcView GIS. A “Design Notebook” containing innovative design options for the Willamette riverbank was developed for the use of both public and private developers. The options were designed to create new models for an urban riverfront while protecting threatened fish species. Incorporated into the analysis of existing conditions is a description of the defining characteristics of the Willamette River Downtown area. The notebook consists of 4 major chapters: Inventory and Background, Operating Instructions, The Design Worksheet, and Design Solutions. The Design Notebook process was carefully coordinated with the National Marine Fisheries Service, US Army Corps of Engineers, Oregon Division of State Lands and various bureaus within the City of Portland. This project received a National ASLA Honor Award in 2002 and an Oregon Chapter ASLA Merit Award in 2000.

Gabriel Park Water Quality Project

The Fanno Creek watershed is heavily impacted by urbanization. Urban streams are suffering from increasing impervious surfacing that results in increased runoff and higher stream velocities. Gabriel Park is symptomatic of these factors: swales have become unsafe gullies; forest groundcover vegetation is absent; park lawns have become severely compacted through overuse and provide little infiltration. The Vermont Tributary of Fanno Creek, which runs through the park has been severely impacted by those factors. GreenWorks developed several concepts to improve water quality for surface runoff in the park and presented these to three neighborhood groups. We provided schematic designs for various stormwater mitigation options, including: a wet pond/marsh treatment system; forest ground-floor revegetation; biofiltration swales; and creation of a wet meadow. GreenWorks provided final design and bidding documents.

Farewell Bend State Park

GreenWorks was part of a multi-disciplinary team working for Idaho Power to conduct a site assessment and prepare conceptual alternatives to stabilize bank erosion occurring along a half mile section of the west bank of the Snake River in Farewell Bend Sate Park. The primary goals were to identify causes of erosion and develop concepts that would stabilize the shoreline and control the active erosion of the river bank. Additional sub goals included minimizing impact to cultural features, accommodate park use and integrate and enhance habitat elements to the extent possible. During the construction documentation phase, GreenWorks, working with Inter-fluve, researched and developed an innovative method for establishing planting within the rock revetment bank stabilization design.

Albany Stormwater Standards

GreenWorks has worked over the past several years with City of Albany staff to develop stormwater quality standards for development to meet DEQ regulatory requirements.  The products include new and  updated sections of City Administrative Codes, Development Codes, Engineering Standards, Standard Construction Specifiations, and Standard Drawings.   The draft products are currently in the public review process, with adoption and implementation tentatively planned by the end of 2014.  Draft documents are all available for review on the City of Albany/Public Works/Engineering web page.

Human Access Project

With the completion of the Big Pipe in 2011, water quality in the Willamette has improved by leaps and bounds. In the wake of this achievement, Will Levenson, head of the non-profit Human Access Project, is leading an effort to change people’s perceptions of the river and encourage recreation in the water and along the waterfront.
GreenWorks became involved in the Human Access Project in November 2012, bringing our extensive experience designing places for people within sensitive natural environments, which focus on balancing access with habitat conservation.
This balance is certainly a key consideration as the Human Access Project gains momentum through additional community outreach and scaled interventions along the Willamette’s shores. Greenworks is honored to be contributing to this worthy cause and looks forward to witnessing the transformation of Portland’s largest public open space in the years to come.
