Land subdivision is the first step in the process of community development. Once land has been cut up into streets, lots and blocks, and publicly recorded, the correction of defects is costly and difficult. Subdivision of land sooner or later becomes a public responsibility, in that roads and streets must be maintained and various public services customary to urban areas must be provided. The welfare of the entire community is thereby affected in many important respects. It is, therefore, to the interest of the public, the developer and the future owners that subdivisions be conceived, designed and developed in accordance with sound rules and proper minimum standards.
The following subdivision regulations guiding the planning commission are designed to provide for the harmonious development of the regional area and its environs; to secure a coordinated layout of roads with other existing or planned roads in or near the region; for adequate open space for traffic, light, air, and recreation; for the conservation of or production of adequate transportation, water, drainage and sanitary facilities; for the avoidance of population congestion; and for the avoidance of such scattered or premature subdivision of land as would involve danger or injury to health, safety, or prosperity as set forth under the provision of Section 13-303, Tennessee Code Annotated.
