5:119. Intent.

This chapter is intended to require city review and approval of the development of certain buildings, structures and land uses and the creation of new lots, all of which can be expected to have a significant impact on adjacent parcels and land uses, traffic patterns, natural features and the character of future development. It is further the intent of this chapter to provide for the preservation and management of significant natural features through city review, as well as to achieve harmonious relationships of buildings, structure and uses, both within a site and with adjacent sites; safe and convenient traffic movement, both within a site and in relationship to access streets; and appropriate public and private infrastructure.
