provided a disclosure that indicates that the property offered for sale is located in an area subject to aircraft flyover noise(MHMP Section 11.3.5,Implementation[b]). Agricultural Activity Noise The College Park project would not create new agricultural areas,and thus would not generate new agricultural- related noise(e.g.,tractors,field hands).However,the project would result in the development of new noise- sensitive land uses(e.g.,residential,school,park,place of worship)in an area that would continue to be affected on an intermittent basis by noise generated by agricultural activities.Both on-and off-site agricultural activities would be permitted to continue under the County's Right-to-Farm Ordinance. Agricultural activities on and near the project site would continue to include the use of various types of heavy equipment.The operation of heavy agricultural equipment can generate noise levels of approximately 85-dBA Lq at 50 feet(EPA 1971).Noise generated by agricultural machinery would not be transportation related and,therefore,would be subject to the San Joaquin County Development Title's maximum noise standards for stationary sources of 50 dBA Lq and 70 dBA L.,during daytime hours,and 45 dBA Lq and 65 dBA L.during nighttime hours at the property line of the nearest sensitive land use.Depending on the duration and time when these activities occur,resultant noise levels at nearby proposed noise-sensitive receptors could potentially exceed the standards of the San Joaquin County Development Title. The College Park project includes edge treatments that would prevent noise from off-site agricultural operations near the eastern and western boundaries of the project site.The treatment along the west edge would address the areas where residential uses would directly abut the Alameda County line,where the nearest agricultural activities could occur.This treatment would consist of a minimum 100-foot setback from the community boundary to the nearest dwelling,the setback occurring in the rear yard of the residential properties, and a continuous security fence or wall along the property line with planted vines.The treatment along the west edge where the proposed community college would directly abut the County line would have a minimum 100-foot building setback from the community boundary to the nearest building.The treatment along the east edge of the project site would be defined by the Mountain House Parkway right-of-way,plus a minimum 32-foot additional setback.The edge treatments incorporated into the College Park project are pursuant to the"Agricultural Equipment—Community Edges"policy of the MHMP(previously described)and would help to reduce off-site agricultural noise as perceived at proposed noise-sensitive land uses.The industrial,office,and commercial land uses proposed along the west side of Mountain House Parkway would provide additional noise shielding, although these land uses are not likely to be developed until after the proposed project's residential neighborhoods are developed and inhabited. Despite the above,agricultural operations would continue on undeveloped portions of the project site while development occurs.Machinery operating as close as 50 feet to the nearest property line of a newly inhabited residence or school could exceed County noise standards. Such exceedances would occur infrequently and intermittently,only when agricultural machinery is operated in close proximity to newly inhabited residences, and would eventually be eliminated as agricultural uses on the site are replaced by urban development. Still,a potential would exist for exceedance of the County noise standards at the proposed residences associated with existing agricultural activity.A significant impact could occur. Industrial and Commercial Noise The area adjacent to the southeast portion of the project site and the interchange of I-205 and Mountain House Parkway is the future site of an industrial park/freeway/commercial area.The specific types of land use to be developed at this site and the timing of its development have not been determined.Potential sources of noise associated with these types of land uses can vary substantially.Commercial and industrial land uses may include noise sources, such as the use of forklifts for loading and unloading materials, and the use of machinery associated with light manufacturing or industrial processes.Although not part of the College Park project,this area is inside the Mountain House community and subject to the MHMP's maximum allowable exterior noise College Park at Mountain House Specific Plan III Draft EIR EDAW San Joaquin County 4.13-29 Noise
