Document Description
Request to expand the herd of an existing dairy facility located on two parcels across a total of 124± acres, in the A-2-40 (General Agriculture) zoning district. The applicant proposes to expand the herd from 1,076 to 2,200 mature cows, which includes an increase of 1,020 milk and 85 dry cows. Under this request, the applicant also proposes to increase support stock numbers by 1,280 for a total of 1,900 heifers. The increase to support stock will consist of 600 heifers 15-24 months old; 600 heifers 7-14 months; 350 calves 4-6 months old; and 350 calves 0-3 months. Additionally, the applicant proposes to construct two shade barns on APN: 057-013-019 and two free stall barns on APN 057-022-012 totaling 146,650 square-feet of building space within the existing dairy production area boundary. The applicant anticipates an increase of 3,135 cubic feet of additional manure per day generated from the proposed herd expansion, for a total of 5,889 cubic feet of manure per day. Nutrients produced from the herd will be utilized to fertilize irrigated cropland on parcels surrounding the existing dairy operation owned by the property owner as well as two parcels located to the north and east of the dairy that are not owned by the dairy property owner. Hours of operation are 24-hours a day, seven days a week. There are currently four single-family dwellings onsite which are occupied by employees. The proposed request is expected to increase the number of employees by one for a total of six employees on a maximum shift. No additional housing is proposed as part of this request. The applicant does not anticipate any customers onsite. The dairy currently receives three visits for tallow and veterinary services every two weeks, and a combined total of four milk and feed truck trips per day. The proposed request is expected to increase the number of feed truck trips from one to two per day, and milk truck trips from three to six per day for a new combined total of eight feed and milk truck trips per day. The existing facility is currently improved with 306,674± square feet of dairy and residential building space and approximately 26± acres of corrals, storage ponds, and feed storage. Both parcels used for the dairy are served by private wells and septic systems. APN 057-013-019 has access to County-maintained Elaine Road and APN 057-022-012 has access by way of South Faith Home Road, a County-maintained road.
