Request to expand an existing dairy facility located on a parcel of 79.74 ± acres, in the General Agriculture (A-2-40) zoning district. The applicant proposes to expand the herd from 1035 to 2300 mature cows, which includes an increase of 1065 milk and 230 dry cows. Additionally, the applicant proposes to increase support stock numbers by 740 for a total of 1690 heifers, 15-24 months old. The project also proposes the construction of three new animal housing structures (roof only) totaling 236,000± square feet in size within the existing dairy production area boundary. The applicant anticipates an increase of 3,385 cubic feet of additional manure per day generated from the proposed herd expansion for a total of 6,094 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. Hours of operation are 24-hours a day, seven days a week.
There are currently six single-family dwellings onsite occupied by dairy workers. The proposed request is expected to increase the number of employees from eight to twelve and 8 employees will live on site. No new employee housing is proposed as part of this request. The applicant does not anticipate any customers or visitors onsite. The proposed request is expected to increase the number of feed truck trips from four to six per week and from two milk truck trips to three per day. The number of tallow truck, and veterinary trips are not expected to increase as part of this request. The existing dairy facility is currently improved with 312,285± square feet of building space. The project site is served by private well and septic system and has access to County-maintained Central Avenue. Confined Animal Facilities (CAF), which include dairies, are considered to be permitted agricultural uses in the A-2 zoning district; however, a use permit is required for new or expanding CAFs requiring a new or modified permit waiver, order, or Waste Discharge Requirements (WDRs) from the Regional Water Quality Control Board (RWQCB), where the issuance of such permit, waiver, order, or WDR requires compliance with the California Environmental Quality Act (CEQA) (Section 21.20.030 (F) of the Stanislaus County Zoning Code). The County adopted the use permit requirement in 2003 in order to allow the County to facilitate the environmental review (in accordance with CEQA) required for issuance of any permit, waiver, order, or WDR by the RWQCB.
