12th Avenue Green Street

  • Location: Portland, Oregon
  • Designer: Kevin Robert Perry, ASLA
  • Client: Cith of Portland Oregon
  • Last Updated: Feb 22 2007

The 12th Avenue Green Street project disconnects street stormwater runoff from a storm sewer that drains directly into the Willamette River and manages it on-site using a landscape approach. Stormwater runoff from SW 12th flows downhill along the existing curb until it reaches the first of four stormwater planters.  A 12-inch curb cut channels the street runoff into the first stormwater planter. Once inside the planter, the water is allowed to collect until it reaches a depth of six inches. The landscape system within each planter allows the water to infiltrate in the soil at a rate of four inches per hour. If a rain event is intense enough, water will exit through the planter’s second curb cut, flow back out into the street and eventually enter the next downstream stormwater planter.

The SW 12th Avenue Green Street Project has received a national award of honor from the American Society of Landscape Architects (ASLA). Bureau of Environmental Services green street specialist Kevin Robert Perry designed the innovative street stormwater project.

Stata Center Outwash Basin

  • Location: Cambridge, MA
  • Designer: Olin Partnership and Nitsch Engineering
  • Client: MTI
  • Last Updated: Feb 20 2007

 The designed the landscape for this Frank Gehry building on the MIT campus.  Nitsch Engineering designed the storm water bioretention system. Wendy Goldsmith Bioengineering did the planting design.  This system is multi functional: it is a constructed wetland that detains runoff to reduce peak downstream flow, the wetland's plants and planting medium cleanses the runoff, it allows some ground water infiltration, and a solar powered pump pushes the water back up to the wetland after its first pass through the water quality polishing cycle.  This pumping not only cleanses the water a second time it also maintains the wetland moisture level required for plant health and vigor.  The Olin concept was based of creating a "slice of new England," a piece of a riverine and wetland system.  MIT was not very interested in green design when these ideas were put first forth by the landscape architects and engineers. Once the university realized that the EPA would reduce some of their pending fines for other violations, they became supporters of these ideas! (Tim Baird)

10th @ Hoyt

  • Location: Portland, Oregon
  • Designer: Steven E. Koch, ASLA, KLA - Koch Landscape Architecture
  • Client: Rob Hinnen of Trammell Crow
  • Last Updated: Feb 16 2007

10th@ Hoyt is the interior courtyard of an apartment complex in Portland, Oregon’s Pearl District. The design, by Koch Landscape Architecture is inspired by forms, textures, and colors of Persian gardens, presents an inward-oriented private oasis focused on a playful-yet-elegant illustration of stormwater collection, storage, and reuse.  Stormwater from the roof travels down into the courtyard via copper downspouts in three locations; in each spot the water then travels via eye-catching chutes, runnels, and level spreaders of concrete, copper, and Cor-ten steel, eventually disappearing into raised basins filled with river stones.  The water is then stored for up to 30 hours in a 4000 gallon cistern below grade.  During the storage interval, the water is recirculated into elegant Cor-ten fountains in the courtyard.  Detained runoff is then slowly released to the city stormwater system.  Benjamin Rodes from Department of Landscape Architecture at University of Idaho has provided a wonderful Case Study of 10th@Hoyt.

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.

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.

Liberty Centre

  • Location: Portland, Oregon
  • Designer: Portland Bureau of Environmental Services
  • Client: Portland Bureau of Environmental Services
  • Last Updated: Feb 4 2007

Stormwater planters are constructed in existing landscape areas next to the parking deck. Half of the runoff from the parking deck discharged to the eastern planter and half is discharged to the western planter.The planters slope to one end, where runoff ponds to a depth of 11 in. before overflowing into the combined sewer via a raised drop inlet.Colorful bioretention plantings includes a variety of native trees and vegetation, improving the urban environment and aesthetic appeal of the property and surrounding commercial area.

110 Cascade

  • Location: Seattle, WA
  • Designer: Mara Rogers - mara.rogers@seattle.gov
  • Client: Seattle Public Utilities and Seattle Department of Transportation
  • Last Updated: Feb 4 2007

Seattle Public Utilities and Seattle Department of Transportation replaced the existing ditch and culvert system along 4 blocks of Northwest 110th Street, between Greenwood Avenue North and Third Avenue Northwest in the Piper's Creek Watershed with a "Cascade" model natural drainage system as part of the Street Edge Alternatives program.  An online tour of the Street Edge Alternatives program is provided by the City of Seattle. Vegetation and swales that form part of the system help to filter out and break down polluted runoff, before the water reaches Pipers Creek.  The project is a series of stair-stepped natural pools that slow damaging stormwater flows, reduce flooding, and trap pollutants before they reach Piper's Creek. Stormwater flow from approximately 21 acres is managed through this natural infrastructure. (from Seattle Public Utilities)
