I think the bit about 'Investment in new services and infrastructure....' is not strong enough and suggests housebuilding comes before these services and may not happen at all if the 'investment' doesn't materialise. Services and infrastructure such as schools and healthcare should be the first consideration for housing plans and developers should be required to build these things first rather than an afterthought.
Should we also go further and imagine a Medway where residents are in housing sufficient for their needs - for instance older residents in larger properties are encouraged/supported to downsize for both energy efficiency and to provide houses for growing families.
The vision should also go further on waste and explain what is meant by the waste hierarchy as most won't understand this. We should be envisaging a Medway where people are encouraged/supported to re-use and share items rather than just buy and chuck them away. Residual waste levels reduce and we have streets free from litter and other types of antisocial behaviour.
