southeasterly trending direction(Figure 4.2-1).These irrigation canals supply the existing agricultural operations <br /> on the project site, as well as agricultural operations downstream and southeast of the project site. <br /> EXISTING AGRICULTURAL PRACTICES <br /> The two on-site dairies operate 24 hours a day, seven days a week.The dairies are often the source of cow and <br /> wastepond-related odors, carried by prevailing winds going toward the east. See Section 4.12,"Air Quality,"for <br /> further discussion. <br /> The Mountain House Master Plan(MHMP)area,including the College Park project site,includes agricultural <br /> lands planted with alfalfa,beans,wheat,and Sudan grass,and irrigated and non-irrigated pasture.These lands <br /> have been chemically sprayed for pest control in the past.The types of chemical applications are directly related <br /> to the type of crop.The chemical properties and the methods of application vary; some crops are treated with <br /> aerial application,by helicopter or fixed-wing aircrafts; others are treated with a ground application. Generally, <br /> the frequency of pesticide spraying for alfalfa is two to four times per growing season. Other crops, such as oats, <br /> beans,and wheat,are not usually sprayed(SJCCDD 1994).Pesticides typically used for these crops include <br /> paraquat(herbicide),2,4-D (herbicide), Roundup (herbicide),and Sevin(insecticide). Other pesticides, including <br /> herbicides and rodenticides,may be used(Lanigan 2004).Frequency of spraying varies from year to year, <br /> depending on whether there are problems with pests such as weevils.Use of restricted pesticides is required to be <br /> reported to and approved by the San Joaquin Agricultural Commissioner's Office,which enforces U.S. <br /> Environmental Protection Agency's requirements, and the California State Agricultural Commission. See Section <br /> 4.9, "Public Health and Safety,"for further discussion. <br /> EXISTING IMPORTANT FARMLAND <br /> As indicated in Figure 4.2-2,the Farmland Mapping and Monitoring Program of the California Resources Agency <br /> designates approximately 55%of the 815-acre College Park project site and the off-site infrastructure site <br /> location as Prime Farmland, 35%as Farmland of Local Importance, 5%as Urban and Built-Up Land, and 5% <br /> (Pombo property)as Other Land(California Department of Conservation[CDC]2000).Prime Farmland is <br /> defined as land that has the best combination of physical and chemical characteristics for the production of crops, <br /> including the soil quality, growing season, and moisture supply needed to produce sustained high yield crops,and <br /> must have been used for irrigated agricultural production at some time during the 4 years before the mapping date. <br /> Farmland of Local Importance is defined as land of importance to the local agricultural economy, as determined <br /> by each county(CDC 1994).Together,the Prime Farmland and Farmland of Local Importance on the project site <br /> (730 acres total)represents"Important Farmland." <br /> EXISTING WILLIAMSON ACT LANDS <br /> T <br /> Several parcels within the project site and off-site infrastructure locations are currently under Williamson Act <br /> contracts(Figure 4.2-2). The Williamson Act is state legislation that allows landowners to enter into an agreement <br /> ., with counties whereby the property owners agrees to maintain the land in agriculture for a period of at least 10 <br /> years.In exchange,the landowners are allowed a reduction in property taxes for the subject parcel. Since the early <br /> 1980s,approximately 16 million acres of land statewide have been enrolled under Williamson Act contracts <br /> (CDC 2004). For the 2001 tax year(the most recent data available), San Joaquin County had 542,916 acres of <br /> farmland under Williamson Act contracts,including continuing contracts and nonrenewals.This is 738 more <br /> acres than the previous year,but a decrease of 16,871 acres from 1991.The CDC estimates San Joaquin County <br /> had 542,178 acres of land under Williamson Act contract in 2000 and 559,787 acres in 1991 (CDC 2004).The <br /> ` long-term trend is thus a decrease in farmland and farmland under Williamson Act contracts Countywide. <br /> As indicated in Figure 4.2-2, six project parcels are still under active Williamson Act contracts.These include <br /> k' Assessor Parcel Numbers(APNs)209-450-14 and 209-450-15 (Souza),209450-16(Teixeira),209-060-11 and <br /> College Park at Mountain House Spec'rfic Plan 111 Draft EIR EDAW <br /> San Joaquin County 4.2-3 Land Use and Agriculture <br />
