In considering whether to make an agreement as an alternative to reserving land within the site which will remain the primary requirement the authority will have to consider a number of important issues, the most important of which will be the need to counteract undue social segregation in the area. Social integration does not mean making people live side by side. Some voluntary housing bodies argue against "pepper potting" houses through estates for management reasons. It does mean ensuring all the people of a community, of all kinds, are represented within a locality, going to the same shops and schools, benefiting from the same community facilities and transport links.
