Siskiyou Green Street

  • Location: Portland, OR
  • Designer: Bureau of Environmental Services
  • Client: City of Portland
  • Last Updated: Mar 11 2007

Siskiyou Green Street Project in a leafy residential neighborhood of Portland, Oregon.  This "stormwater curb extension" as described by the Portland Bureau of Environmental Services adds "bump-outs" to extend the curb line into the neighborhood street near an intersection.  Thickly planted with multi-textural sedges and ferns, and intersected by river rock dams and weirs, these right-of-way extensions catch street runoff and serve as biofilters. A simple sign standing in one of the landscaped extensions clearly shows, with brief text and images, how the system works and what it accomplishes.  This humble project provides a noteworthy example of multi-function: the extensions not only filter and slow runoff, but they also serve as traffic calming devices by narrowing the roadway while the lush plantings provide streetscape beautification that is compatible with residential plantings in the area.  The project also stands as a virtual exemplar of transferability, as it's very easy to see how this strategy could be used in other neighborhoods.  Indeed, according to Tom Liptan, Environmental Specialist for the City of Portland's Bureau of Environmental Services, residents of other Portland neighborhoods are now requesting the addition of this feature to their own streets, and are willing to open their own wallets to pay for this streetscape amenity.

Willow Run Park

  • Location: Camp Hill, PA
  • Designer: Chris
  • Client: Camp Hill
  • Last Updated: Feb 13 2007
Willow Run is located in Camp Hill Borough, Cumberland County Pennsylvania along 1,400 feet of an unnamed tributary of Cedar Run.These ground-fed, cold water streams are perfect habitats for trout.The area abounds with springs that once made Cedar Run one of the finest trout streams in Pennsylvania.

In the top portion of the park, water will naturally flow towards a low point in an ongoing attempt to find the fastest way across the land.This process often times results in organic shapes and forms and fluid landscapes.Over the course of time Willow Run has become a circuitous, meandering stream and provided the inspiration for the design in the northern third of the park.This area of the park allows visitor to see how organic, flowing, and at times untamed forms can be utilized in mitigation of storm water.The organic forms created in this area provide basis for comparison to the two other areas of the park.

Contrasting the first area of the park, the middle section is created with the interaction of humans and natural processes in mind.Humans influence on nature can be seen at Willow Run in the bank erosion, sedimentation and erosion.The design in the middle section demonstrates alternative ways to the mitigation of stormwater as a fusion between natural forms and constructed forms takes shape.This area creates a transition between the organic section of the park and the urban section of the park.

The third area is designed with an urban setting in mind as it played into its adjacency to Camp Hill's main street.This area of the park utilizes rigid forms and materials (juxtaposing the first section of the park) to demonstrate that the mitigation and cleansing of water will work despite the form that is used or the setting.

Tanner Springs Park

  • Location: Portland, OR
  • Designer: Dreiseitl, GreenWorks
  • Client: Portland Parks and Recreation
  • Last Updated: Feb 4 2007

GreenWorks collaborated with Atelier Dreiseitl of Germany to design an urban park in Portland's Pearl District. Envisioned as an urban park with a wetland focus, the park serves many residents in the newly developing Pearl District neighborhood. The design features innovative uses of water and stormwater, creating a refuge for people and wildlife in the midst of this bustling downtown neighborhood. The design process was highly interactive and involved the citizens of Portland through a series of interactive public workshops. (from GreenWorks)

  • Location: Maplewood, MN
  • Designer: Joan Naussauer, Chris Cavett
  • Client: City of Maplewood
  • Last Updated: Mar 11 2007
The City of Maplewood, Minnesota, working with designer Joan I. Nassauer, Professor of Landscape Architecture at the University of Michigan, created lovely formal homeowner rain gardens that set a new standard for attractiveness. This 1996 project took the rain garden movement even farther by making a rain garden, and stormwater management, part of an accepted formal landscape element for residences. Joan Nassaur's professional skills, and interests in both landscape design and in watershed planning, resulted in lovely garden designs that are very well accepted in Maplewood. The project was funded in part by Legislative Commission on Minnesota Resources.

Cedar River Education Center

  • Location: Cedar Falls, WA
  • Designer: Jones & Jones Architects and Landscape Architects, Ltd.
  • Client: Cedar River Watershed Education Center
  • Last Updated: Feb 14 2007

At the Cedar River Watershed Education Center runoff is conveyed from the roof via downspout into a sculpted basin; from that point the water traverses a stone terrace in a most elegant meander.  That water trail is clarified, enhanced, and made safe by a cover of steel grating perforated with lilting curves that extend the "liquid" theme, alternating with river pebble fill.  Whatever the compositional decision, manipulation of the line of the water trail is a great design opportunity in artful rainwater design.  Mark Puddy from Department of Landscape Architecture at University of Idaho has provided a wonderful A Case Study: Cedar River Watershed Education Center.
