The purpose of this chapter is to provide a way to develop land needed for and adapted to residential use at a population density requiring both public water supply and sanitary sewer system, but which area does not contain one or both of these utilities at the time of development. It is necessary that Utility Transition Areas be confined to undeveloped areas adjacent to existing urban areas containing the needed utility services so that in due time these services will be available. The provisions are made allowing a resubdivision of the original plat at a later date when utility lines are available so as to induce development in an economical manner and orderly arrangement rather than unsound scattered type of development.
