We integrate green infrastructure into our sites including parks, playing fields, woodlands and gardens, sustainable drainage features and planting, alongside roads and streets. This helps create a strong sense of place, supports water management, reduces flood risk and helps to enhance biodiversity.
We launched our Guide to Green Infrastructure in 2018, which incorporates recommendations from the Wildlife Trust. It aims to support our teams to plan and implement effective green infrastructure that supports biodiversity. Next we are developing a Home for Nature Toolkit, a compendium of practical measures which can be implemented on our sites to enhance biodiversity.
Recent examples include our site in Stepps, West Scotland, where we have improved local marshland, with the creation of new ponds and channels and refuge areas for amphibians, as well as bird and bat boxes and a new butterfly meadow and bare ground areas. Two nature trails have been added to encourage residents to get out and enjoy the natural environment. The site also includes amphibian tunnels under the new roads, enabling frogs, toads and newts to migrate safely from the marshland to the neighbouring loch.
At Cambourne, six hectares of new lakes and wetlands were created providing areas for recreation and bringing new species of birds, mammals and insects onto the site. At The Chilterns development we have incorporated wildlife-friendly planting such as mature trees and native shrubs. And at Chase, in partnership with the Wildlife Trust, we developed a comprehensive landscape strategy to enhance its nature conservation value.
Brown and green living roofs have vegetation planted or allowed to grow on them. They provide a range of benefits including reducing stormwater run-off and wildlife habitats. Our City Mills development in London is being built with green and brown roofs, our Chobham Manor development is integrating brown roofs and green walls and Academy Central in London also includes green roofs.
