The Non-Urban District encompasses areas within which rough natural topography, surface or subsurface geological conditions or location in relation to developed areas creates practical difficulties in providing and maintaining public roads and public or private utility service and facilities including sewage treatment, water and power supply. The Non-Urban District also encompasses areas in which significant non-urban uses have been established. The purpose of the "NU" Non-Urban District regulations is to guide and coordinate development within the City of Lake Saint Louis in order to secure the appropriate development of the physical environment.
