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 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?

URSULA aim & methodology Recommendations Assessment of interventions Indicators Interventions, innovations New tools Data & models Stakeholders

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 …

Sheffields 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 Sheffields 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) Dortmunds green radial plan

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?

Maximum blue-green

Compromise?

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