A. 
The agricultural use district (AG) is a primary zone classification permitting essentially open land uses such as grazing lands or pasture, agriculture, and development of part-time small tract farming and other compatible uses of an open nature such as a cemetery, park, and recreational or similar uses on land which has favorable combinations of slope, climate, availability of water, or soil conditions. This zoning classification is intended to be applied to some portions of the city that are designated as agriculture or as urban reserve under the city of Richland comprehensive plan.
B. 
The suburban agricultural use district (SAG) is a zone classification providing for residential areas, rural in nature, with sufficiently large lots to allow for the maintenance of certain animals and farm crops, while at the same time establishing and maintaining a living environment of high standards for residential uses. This zoning classification is intended to be applied to some portions of the city that are designated low-density residential (zero to five dwellings per acre) under the city of Richland comprehensive plan.

d. 
A maximum of two animal units (one animal unit equals approximately 1,000 pounds of animal weight) may be kept per one acre gross pasture area.

i. 
Horses and similar animals: one year from date of birth;
ii. 
Cattle and similar animals: one year from date of birth;
iii. 
Sheep, goats, and similar animals: six months from date of birth;

In addition, a fence must be constructed prior to the acquisition of any large livestock to ensure containment of the livestock on the premises;
4.

Standings under roofed stable must be made of material and which provides for proper drainage so as not to create offensive odors, fly or insect breeding, or other nuisances.
Manure must be collected at least once a week and shall be disposed of in one or more of the following manners:
i.
Placement of manure in a fly-proof container with periodic removal of manure from the lot;
ii.
Adequate burying of the manure;
