2 Scottish Natural Heritage Green Infrastructure Design for Multiple Benefits 1. Design for multiple functions and uses 2. Design for connectivity 3. Consider opportunities across the grey-to-green continuum 4. Take a place-based approach 5. Design for the long-term

3 Adapted from: Green Infrastructure Design and Placemaking, 2011: 17 Scottish Natural Heritage 1. Design for Multiple Functions and Uses Single space Single purpose Single space Designed for multiple functions/uses Single space Delivers multiple benefits INCREASING VALUE

4 Even in a small space you can combine functions water attenuation; amphitheatre for local events; space for learning; a local pocket park in the heart of the city; access to a hidden watercourse; Scottish Natural habitat value; Heritage seasonally Dualchas responsive Nàdair planting na h-alba design.

5 Combines recreation and leisure; access to a previously hidden watercourse; additional water attenuation at times of peak flow; sport facilities; running circuits; ecological value Scottish Natural Heritage SUDS located within the park boundary. Design picks up on the naturalistic character of flood alleviation scheme. Grassland management within the wider park also appears to be influenced by the flood alleviation scheme, with longer, meadow areas.

Design for Connectivity Single space Single purpose Single space Designed for multiple functions/uses Single space Delivers multiple benefits Single spaces Designed for multiple functions/uses Connected and linked as part of a network INCREASING VALUE

10 Combines: access; seating; sustainable drainage; planting design; overlooked by a development frontage; creates a green setting for development; habitat value Scottish Natural Heritage Plan for people and wildlife!

11 3. Think about opportunities across the Grey-to-Green Scottish Natural Heritage Continuum Trees for shade Cycle storage Placemaking street trees Bug-friendly Bollards Permeable paving Trees as speed calming Green roofs Green walls Green walls Flood storage

12 Scottish Natural Heritage Repaired river wall of low aesthetic value with the addition of timber cladding to provide some habitat value. Simple re-structuring: truncated river wall with timber edging, creating a 7m-wide saltmarsh terrace. High aesthetic value, seasonally responsive, additional flood storage and storm surge protection, ecologically valuable one of the most important Sea Bass nurseries in the southeast of England.

13 4. Take a place-based approach: Scottish Natural Heritage Understand existing place assets how can they shape place character? Think about users of all ages and abilities where they want to go, what they want to be able to do Look closely at topography and drainage Identify natural assets and work with nature Integrate the green infrastructure vision with the overall place vision Green infrastructure & built form work together

14 5. Design for the long-term: Scottish Natural Heritage Plan for long-term stewardship and place-keeping from the outset! Working with nature is often cheaper and more sustainable
