Learning Point 98 Liveable Places: Green Networks
1
INTRODUCTION
“Resilience is the capacity of a system to deal with negative change without collapsing, to withstand shocks, and to rebuild itself and learn”; places which go ‘boing!’
WHAT ARE LEARNING POINTS? Learning points share what people have learned from their experience in regeneration - from people working or talking together, or from research into issues and evaluation of what is happening. Learning points can help people and organisations to improve their practice through identifying what works and what doesn’t. The views described in learning points do not mean that the Scottish Centre for Regeneration (SCR) or the Scottish Government necessarily support them. They simply reflect what has been debated and what those involved in the event considered useful learning and lessons from their perspectives. WHAT IS THIS LEARNING POINT ABOUT? This Learning Point captures the key points from the presentation given at the Design Skills Symposium in Stirling on 27 September 2011 by Max Hislop. Max is Programme Manager at GCV Green Network Partnership. GCV (Glasgow Clyde Valley) Green Network Partnership is one of four partnerships delivering aspects of the Central Scotland Green Network, which is part of the National Planning Framework.

Green Networks The Central Scotland Green Network defines a green network as ‘a strategic network of woodland and other habitats, active travel routes, green space links, watercourses and waterways, providing an enhanced setting for development and other land uses, and improved opportunities for outdoor recreation and cultural activity.’ The purpose of a green network – • Landscape enhances a place’s identity • The provision of walking and cycling routes • It links habitats together • A good environment can attract investment

GCV Network describe these as the outcomes of a green network such as theirs • Can make stronger communities • Leads to health improvements • Creates biodiversity • Helps the development of enterprise Government (Scottish Government in Delivering Better Places and A+DS) say that green infrastructure should be an integral part of the development process and that the design of external spaces is as important as of the buildings, but green organisations have not articulated the case for this strongly enough, and green infrastructure and landscape are still often an afterthought.

There are 5 design elements to an Integrated Green Infrastructure (IGI)1. Habitat networks. These can improve the environment for development, not constitute a restraint on it. 2. Access networks. GIS in particular can be used to help focus on opportunities for improving access 3. Stewardship over time. Resources are needed to maintain and manage IGI 4. Green and open space, including both formal and informal spaces. Connecting these into a green network enhances their individual benefits. Greenspace Scotland’s new Greenspace map of Scotland is an excellent startingpoint for this. 5. Water management. SUDS is the law now, so there is an automatic opportunity to create a ‘naturalised SUDS’ using, for example, green roofs, swales, ponds and wetlands, and mimicking nature through use of open streams, rather than culverts.
Integrating Green Networks 5 Design elements:

BCV have commissioned Collective Architecture and AECOM to do four studies showing how water management can be used as the basis for development of IGI. In the study for the Jackton and Gill Burn Valley community growth area, the process started by mapping the water journey, and proceeded to build physical infrastructure around this in support of that. Final master-plan incorporates the same number of houses, but has a much richer environment.
Key Lessons 1 IGI delivers green spaces which are multifunctional and valued 2 There are lots of spatial analyses and tools available to inform the design process of IGI 3 Surface water management should be the starting-point for a development, not the road layout. 4 Access and habitat networks can be aligned with ‘naturalised’ SUDS 5 Stewardship should be designed in to sustain quality and outcomes. Key message of presentation A green infrastructure can deliver unique benefits to a place; the integration of a green infrastructure in the urban development process, in particular one based on the management of water, should be a key driver of a masterplan for the creation or the regeneration of a place.
