In practice, the delivery of a quality green and blue infrastructure network is likely to involve a combination of the options that have been outlined. Option 3 is particularly supported as this offers the most potential to deliver the infrastructure due to developments being specifically required to make on and/or off-site provision. However, to be effective this would need to be supported by a robust green and blue infrastructure strategy which identifies strategic projects that developments will be expected to deliver directly or contribute towards. The Local Plan will also need to consider how to integrate the emerging South Essex Estuary Park proposals that are being prepared by ASELA as their delivery will need to be supported by local plan policies and proposals.
