This study is based on identifying and analysing the problems which arise from suburban expansion into the urban fringe; and on suggesting certain policy measures which could serve as a basis for directing development in such a way as to avoid these problems. The urban fringe is recognized as the contact zone between the city and the countryside. As such, it experiences the major development forces which arise from the growth of the metropolitan population. It is characterised by change and instability; which are reflected in unrealistic land values, speculative land holding, and unproductive use of much of the land. As suburban development encroaches into this zone, so the forces which precede it reach further out into the countryside. Many fringe areas comprise prime farmland and, in some instances, the environmental characteristics of the l and are scenically attractive and offer great opportunities for meeting the outdoor recreational needs of the metropolitan population. The threat to these attributes. constitutes the major problem associated with suburban expansion.

Having established that Constantia exhibits certain problems which are characteristic of the suburbanization of the urban fringe in general, it is necessary to consider how these problems could be resolved. In seeking such solutions, it is not only useful, but imperative, to determine sane framework of what the desired future state of the Valley should be and what role it should perform in the metropolitan context. In other words, what goals should be strived for and what objectives should be aimed at in order to facilitate the resolution of these goals. In establishing this framework, one returns to the basic underlying reasons for public sector intervention in the free market process - as outlined in Section 7.0 of Part One. This being "to regulate individual activity in the interests of the safety, health, morals and general well-being of the whole population" .
