Cambourne A ‘Best Practice’ New Development
“we can build to the of Cambourne… or the standard of Slough”
Jon Rouse, Chief Executive CABE. The Times 2004

“Cambourne has successfully built in biodiversity as an integral part of the Masterplan”
English Nature, Memorandum to the ODPM, 2004
“This good practice example shows how the existing biodiversity was protected and how new wildlife interest can be created”

Cambourne Masterplan
Masterplan drawn up in 1995 by multidisciplinary team led by Terry Farrell
Vision included the following aims (amongst others):• Protect & enhance features of landscape value• Protect & enhance features of ecological value• Enhance biodiversity through habitat creation• Facilitate & encourage movement by foot, cycle & other non-
vehicular forms
• Together these enable the creation of the Landscape Structure Plan (Green Infrastructure for Cambourne).

Cambourne’s Green Infrastructure
Open spaces designed to be multifunctional:
Ecological enhancement
Engineering requirements
Waste disposal
Education
Screening
Shelter
Informal recreation
Formal recreation
Food production
Sense of place / local character
Aesthetic delight
Movement
Range of linked habitats and public realm that provide benefits that far exceed the sum of the individual parts
Cambourne’s Green InfrastructureRange of Green Infrastructure assets at a variety of scales
Inter-relationship of GI with the movement network
• Primary roads and Green Infrastructure• Green Infrastructure and movement• Non vehicular routes and Green

Primary Roads & Green Infrastructure
•Vision:
•Protect and enhance existing features of landscape or ecological value
Primary Roads & Green Infrastructure
•Vision:
•Protect and enhance existing features of landscape or ecological value
Green Infrastructure adds value to the highway design by
• Adding aesthetic delight• Adding wildlife interest/value• Creating natural gateway
features• Creating traffic calming features• Providing highway drainage
Designing the highways and GI together adds value to the development
• Maximises the value of existing features
• Enhances the sense of place• Improves navigability• Improves marketability• Reduces build costs
GI enhances the movement network

Monkfield Wood
•Vision:
•Protect and enhance existing features of landscape or ecological value
Problem:
Existing woodland in centre of development
•Potential to be lost, unloved, uncared for and
a burden on the development
Solution:Maximised it’s exposure•Get people to know its there•Get it overlooked•Get people to see it and use it on a daily basis
Result: Highway and pedestrian network have had a positive effect on the value of this piece of GI
•Well used•Well loved•Well managed•Adds to sense of place•Improves permeability•Improves navigability
The movement network enhances GI
Non vehicular routes•Vision:
•Movement by foot, bicycle and other non-vehicular forms will be facilitated and encouraged
System of safe non-vehicular routes;
•footpaths, cycle ways and bridleways
•Link centres of villages with each other
•Link centre of villages with
schools, shops and business park
•Link centre of villages with
surrounding open spaces
•Use existing landscape features
as basis for greenways
•Incorporate new landscape features
•Incorporate new ecological features
•link the places where people live
with the places people want to and need to visit
•Creates attractive, multi-functional routes
•Maximises value of open space and routes
Increases biodiversity, enhances community – decreases carbon use…
Non vehicular transport
Decreasing car dependency

Lessons to be learnt
Masterplan Lessons
•Create a strong vision
•Ensure client understanding and support for the vision
•Assemble a good design team who understand the vision and support each other
•Create a strong and flexible landscape structure
Green Infrastructure and Movement
•GI can enhance highways
•Highways can enhance GI
•The movement network should be inexorably linked to the GI network
The Value of Green Infrastructure
GI can reduce build costs
GI can improve marketability (residents favourite thing about Cambourne is ‘the environment’)
GI can increase monetary values (premium on property next to open space is 0.44 – 19.97 %)
GI and movement networks can enhance sustainability
Lessons can be summed up by The Cambridgeshire Wildlife Trust…
Natural World MagazineBrain Eversham, Director: Wildlife Trust for Cambridgeshire
“We hope that developers elsewhere will learn lessons from Cambourne and realize that places that are good for wildlife are places people want to live”
