Is this the best we can do?

What is URSULA?
• Urban River Corridors and Sustainable Living Agendas
• EPSRC* funded research project
• A consortium of researchers and stakeholders
• Support for the Waterways Strategy Group and partners
• £2.5M over 4 years from January 2008
• 310 man-months of researcher time
• An opportunity!
*EPSRC = Engineering & Physical Sciences Research Council
URSULA Hypothesis
• There are significant social, economic and environmental gains to be made by integrated and innovative interventions in urban river corridors.
• Can the river improve the city,and the city improve the river,and both improve life for all?

Integrated and Innovative Interventions
• To be determined in alliance with stakeholders What is happening? What are they interested in testing What can we do? What novel ideas do we have?
• Some possibilities …
Sheffield’s Rivers
3 scales – 3 case studies
• Site (building) scale Vulcan House / Kelham Island Goyt
• Reach (street) scale Nursery Street
• Corridor (strategic planning) scale Upper & Lower Don valley regeneration corridors
1. Vulcan House (site) 2. Nursery Street
(reach)
3. Blue-green spaces (corridor)
Site scale – Vulcan House
Vulcan House (Home Office)
• Exceeds BREEAM ‘excellent’ rating Carbon neutral in use water use 20% < than government target
• BUT – how does building design make use of river setting?
The river as an asset
• Vulcan House could be anywhere …
• Some interventions to study: River as heat source or sink Flood-proofing Microhydro
• Once again harness Sheffield’s rivers?• Modern day water wheels?
Kelham Island Goyt
Reach scale – Nursery Street
Nursery St - June 2007
A vision of Nursery St
Multi-functional design of spaces
• Could Nursery Street provide: Flood storage capacity A high quality setting for investment An image changing ‘landmark’ An event space Improved local quality of life Reconnection to the core of the city?
Corridor scale
“The redevelopment of urban river corridors provides us with a once in a lifetime opportunity to recreate open space networks penetrating the heart of the city, and sustainable transport links joining communities with key economic centres” (TW)

Sustainable design
• Maximises Environmental
• Biodiversity
• Pollutant processing
• Flood management
Social• Health and well-being
• Community
• Landscape
Economic• Productivity
• Land values
• Flood damage
• values
• What is the appropriate ratio of Blue : Green : Grey
• How do land values respond to more blue-green space?
• Can flood capacity be built in without losing other values?
• How do we negotiate these trade-offs?

Summary
• The opportunity of urban river corridors
• Sustainable design for social – environmental – economic values
• Investigate interventions at all scales
