17.128.010 Purpose.
The purpose and intent of the acreage residential zone is to provide appropriate regulations governing the division and development of lands designated rural residential in the Marion County Comprehensive Plan. Acreage residential zones are areas that are suitable for development of acreage homesites. Such areas are necessary to meet the housing needs of a segment of the population desiring the advantages of a rural homesite. It is the intent that residential sites be provided with adequate water supply and wastewater disposal without exceeding the environmental and public service capability of the area or compromising the rural character of the area. [Ord. 1271 § 5, 2008; Ord. 1227 § 4, 2006; Ord. 1168 § 5, 2002; Ord. 1125 § 7, 2000. RZ Ord. § 128.010.]

2. The location of the home site ensures that adverse impacts on forest operations and accepted farming practices on the tract will be minimized.
3. The amount of agricultural and forestlands used to site access roads, service corridors, the dwelling and structures is minimized.
4. The risks associated with wildfire are minimized.
B. The owner of a proposed dwelling to be located within 500 feet of the EFU, SA, FT, or TC zones shall be required to concur in the filing of the declaratory statement prescribed in the respective resource zone.
