The purpose of good subdivision and site design is to create a functional and attractive development, minimize adverse impacts, and ensure that a project will be an asset to the City. To promote this purpose, the subdivision shall conform to this article's standards which are designed to result in a well-planned community without adding unnecessarily to development costs. These design controls shall help insure creation of convenient and safe streets, usable lots, space for public purposes, and will minimize the undesirable features of unplanned, haphazard growth. The Planning Commission has the responsibility for reviewing the design of each subdivision early in its design development to insure that all the requirements of these Regulations are addressed.
