A <br />large portion of the site is irrigated for that purpose. In the <br />extreme northeast corner of the site, two houses are rented and occu- <br />pied by the former landowner and family. Other structures in that <br />portion of the site include two barns adjacent to the homes, several <br />corrals, and a high-voltage transmission line traversing the site in a <br />southeast/northwest direction approximately 1,300 feet from the north- <br />east corner of the property boundary. <br />The San Joaquin County Land -Use Map designates the site and its sur- <br />roundings as general agriculture land (GA -40 zoning designation). In <br />addition to livestock grazing, several areas are developed for the <br />cultivation of crops, chiefly grapes. Approximately 20 residences are <br />within 1 mile of the site; the majority are near either Tully Road or <br />Harney Lane. <br />at .0 0. 00r <br />
