The San Joaquin Community Development Department requires that Nitrate Loading/Soil <br /> Suitability Studies be submitted to EHD before submitting the Zone Reclassification <br /> Application. These Studies have been completed and were submitted to EHD on March 22, <br /> 2018 (SR0078905). <br /> § 1.1 The SJC District Viewer Map indicates the subject Parcel is currently 13.09 acres <br /> 'net. The new Tentative Map indicates the property is 11.54 after the LLA. Each proposed <br /> Parcel acreage is illustrated on the Tentative Map. Proposed Parcels 1 and 2 currently <br /> contain a single family residential (SFR) structure. Present land use of the property can be j <br /> observed by the aerial Google Map and consists of open space, numerous trees and wooded <br /> areas. <br /> § 1.2 The Tentative Map has been prepared by Wong Engineers, Inc. and illustrates the <br /> aforementioned existing structures, including: water wells, storage sheds/out building <br /> structures, and other structures itemized in the Legend on the Tentative Map. <br /> As referenced, a description of proposed development is to create four Parcels and a <br /> Designated Remainder from the original 13.09 acre Parcel,through a Minor Subdivision, Lot <br /> Line Adjustment and Zone Reclassification. <br /> § 1.3 The District Viewer Map denoting the location of the property is found in the Appendices. <br /> § 1.4 The Tentative Map illustrates the locations of items currently on the Parcel. Soil Map <br /> historical aerial photos illustrate the property to be vacant. Attached photographic plates show <br /> the actual property and surrounding properties. <br /> §2.0 PAST,PRESENT AND PROPOSED FUTURE USES OF THE SITE <br /> § 2.1 Past utilization of the property has been as residential and a Christmas Tree production farm <br /> up until 2010. <br /> §3.0 IDENTIFICATION OF ALL PAST AND CURRENT SOURCES OF <br /> CONTAMINATION <br /> § 3.1 Discussion of the methods used to research and investigate the potential or known above- <br /> ground and below ground sources of contamination at the site include the following: <br /> The first informational gathering source was direct observation of the entire property, <br /> which is documented in the attached photographic plates. <br /> Nitrogen fertilization of surrounding pasture land, confined animal facilities and row crop <br /> production, probably have contributed nitrogen to the underlying aquifer(s). The on-site <br /> water well was sampled for the Nitrate Loading Study and has a nitrate as nitrate <br /> concentration of 15 ppm and no DBCP/EDB. <br /> Page -3- <br /> Chesney Consulting <br />
