STUDIO for Creative Inquiry
In partnership with
Pittsburgh Department of City Planning
NMR Greenway community design workshop
Vision:
Use community input and involvement to achieve a healthy urban ecosystem, improving
recreational, educational and aesthetic values and finally resolving the century
old problems of water quality
Goals:
1. Clean the stream and keep it clean.
2. Manage the stormwater
3. Restore and support a healthy diverse ecoystem
4. Link Frick park to the Monongahela
5. Provide recreational opportunities
6. Provide educational opportunities
7. Provide a model of institutional partnerships, involve municipalities and
communities.
8. Enhance regional and neighborhood assets, quality of life and property values.
I. Braddock Ave. Node
Vision:
Cultural Restoration, images of a new relationship to stormwater and lost streams
Issue:
Water flow is a safety concern - Invitation for more people to view a natural
phenomenon, means we have to address the safety concerns.
Goals:
- Celebrate the water
- Create cultural connections
- Increase/Expand access to the park
- Encourage community education through pro-active signage and icons
Opportunities:
- Culvert steps should be designed for siting and watching and access for
maint vehicles.
- Establish a warning system for storm surge, provide points of egress.
- Public art opportunity whereby/bells or other devices can be activated
by Stormflow.
- Establish a "stream mark" beginning at Braddock Ave. which can be used
to outline the culverted stream in the upper watershed communities.
- Public / community art opportunity.
- Create community ed center/info at foodland entrance.
- Target homeowner retrofit education to benefit the stream.
Connect to the community explore corporate sponsorship of homeowner retrofit
• Municipal partnerships should be highlighted here.
Challenges:
- Address difficult storm events,
- Constrain access to the culvert.
- Floatables control - Collect debris, allowing for the flow of water.
- Traffic at the entrance is a problem,
- Action: Focus on the design as a local PEDESTRIAN access point.
- Should allow maint sequipment, and cleanout access to the stilling pond.
Maintain parking for business
II. Frick Park Node
Vision:
- Ecological restoration which seperates the stream ecosystem from sewer infrastructure.
Restore the floodplain, stabilizes waterflow and minimizes sewage impact.
- Restoration model for region
- CSO management model for country
Goals:
- Transform the lower Frick Experience
- Create a better ballfield in a new location
- Add stream meanders and flood plain
- Use natural materials and minimize concrete wherever possible.
- Design, plan and institutionalize sustainability
Opportunities:
- Interpret, information- education and establishing signage
- Design for mtn bikers do not ignore them
- Create limited walkways in sensitive areas for ADA access and education
Challenges:
- Reconsider parking- Fern Hollow Creek relationship
- make sure peak parking use is accomodated
- Design with permeable surface or other appropriate stormwater apps.
III. Commercial Avenue Node
Vision:
A meadow restoration would provide the best possible design solution given
the greenway goal of restored and supported healthy diverse ecosystem.
Conflict and Resolution:
While the preference is for a meadow restoration the community planners recognize
the value of diverse human uses and recognize the need for ballfields in Pittsburgh.
If there is to be a ballfield at this site it must consider the following goals
and guidelines.
Goals:
An integrated design including a ballfield, a meadow restoration and an interpretive
center on this singular site. Each element should embrace multi-benefit solutions
and a green design program targeting innovative structure, utilities and systems.
Guidelines:
- Construct a Commercial Avenue pedestrian crossway just south of the
parkway bridge with user activated traffic control.
- Use the Summerset entrance and its periphery for vehicular access and parking.
- Create a sidewalk on the URA (slag) side of the road.
- Put the interpretive center close to the stream but visible from the pedestrian
crossing.
- If the Commercial Avenue bridge is reconstructed, refurbish the underpass
in such a way as to be wildlife friendly.
- Design the playing field to mitigate stormwater flow.
- Preserve as much meadow as possible.
- Develop the interpretive center with an onsite steward and integrate the
ecological reality of the site into the body of the architecture.
- Explore the possibility of removing the concrete fill, and dropping the
entire field to its historic floodplain.
- Use no pesticides or herbicides in the management of the site.
- No ballfield lighting, no sound sytem.
III. Commercial Avenue Node (Continued)
Opportunities:
- Design the site for multi-benefit use, realize diverse human needs and
create a threshold for the diverse audience to access an ecosystem based experience.
- Explore the potential for the existing field to be lowered, allowing for
dual function as playing field and ecologically designed flood plain.
- Design the ballfield and its meadow environ in such a way that stormwater
runoff from the Parkway and Commercial Avenue can be detained, cleaned and
infiltrated into the groundwater.
Challenges:
- Pedestrian crossing the road is a problem
- Parking and vehicular entry onto Commercial is an issue
- Anything that adds to the traffic will negatively affect the wildlife.
- The playing field will interrupt the ecosystem, and minimize biological
connectivity at a key point in the greenway. This is counter to the greenway-plans
stated vision and goals.
IV. Mid Slag Node
Vision:
Restore the site through a mix of ecological and cultural processes. Target
education, art and revegetation.
Issue:
Maintaining silence in the quietest point in the greenway.
Goals:
- Renovate the existing bridge for pedestrians.
- Provide public access to the stream.
- Revegetate steep slopes using natural succession processes.
- Celebrate the heart of the greenway with ecological art.
Opportunities:
- The stream (clean and ecologically restored!).
- Existing bridge and its downstream area,
- Two areas of existing floodplain
Shale cliffs, natural soils and Trillium on the North facing bank.
Challenges:
- Equitable handicap access.
- Integrating the Summerset bridge into the intent of the greenway.
V. Duck Hollow Node
Vision:
Restored riparian ecosystem, minimal effort maximum benefit.
Issue:
- Safe pedestrian connectivity between the slag entry and Duck Hollow.
- Bus service to residents and recreational users.
Goals:
- Celebrate the entry to the slag site/trail.
- Enable public access to the stream and river.
Opportunities:
- Army Corp of Engineers project to improve the aquatic habitat in the NMR
embayment.
- Duck Hollow/flood plain wildlife sanctuary (complimenting the above).
- Celebrate the Greenway entry with a butterfly-habitat garden.
- Simple kiosk with water, toilets, fishermans sink, info board, locking
bike rack.
Challenges:
- Mon-Fayette Expressway (Potential public trail investment opportunity)
- Pedestrian safety under the existing RR bridge.
- Property ownership.
