2) "Retain existing boundary features where possible": This should be priority, for example in the Westgate development proposal: A functional green space between the new and existing urban edge should be retained as a green link to other green spaces. It would serve as a public footway, a visual enhancement for exisiting residents, and a wildlife corridor. This would go some way to retaining wildlife habitat and biodiversity which will be lost to development. It would also contribute to soil water retention and the carbon sink which all to be lost if farmland were developed.
