City Zoning Code

PART 6

ER ESTATE RESIDENTIAL DISTRICT

§ 1-601 Intent.

[8/11/2009]
1. 
To provide areas for medium low-density residential homesites, on land that has minimal farming or ranching value, that create country living in a rural atmosphere while preserving the vegetation, significant geological features, wildlife habitat/corridors, views and privacy, and provide an appropriate transition from urban development to large-lot residential or agricultural areas. The density range is from one dwelling per 4.9 acres to one dwelling per 2.5 acres. Adequate facilities, such as roads, water and sanitation, fire protection, emergency service, and public utilities shall be available to serve these areas.
2. 
Expansion of urban development into rural areas is a matter of public concern because of the potential of unnecessary increases in service costs, conflicts between agricultural and urban activities, and the loss of open space and the natural landscape. Medium low-density residential homesites may be appropriate when located outside the highway corridor viewsheds, depicted on the Douglas County Open Lands Opportunity Map, and when adjacent to residential development of similar or greater density. Development consideration may be given where it would serve to preserve agricultural land or open space, and promote a design that is sensitive to the natural land features in accordance with the intent of the Douglas County Comprehensive Master Plan, as amended.
3. 
Development within this district should provide road connections, between developments, that provide adequate response time for sheriff/fire protection and medical support, and more efficient service delivery such as school busing.
4. 
The ER zone district is characterized by residential homesites and other accessory uses which enhance the basic elements of a balanced residential area such as schools, parks, neighborhood recreational facilities, and open space. Development or use of land in this district is permitted only in accordance with the provisions herein. Land disturbance activities may require permit(s).
