4 Stockton Unified School District <br /> t Geological and Environmental Hazards Assessment <br /> ' CSU-Stanisiaus,Stockton Campus School Site <br /> tPage 15 <br /> �r•� Sanborn maps, dating from 1895, 1917, and 1950 were reviewed. The 1895 map indicates the site as <br /> Grounds of the Slate Insane Asylum with two Male Wards buildings located north of;flora Street and one <br /> Male Wards building on the west side of Grant Street. Five smaller buildings are-unlabeled- and one <br /> t labeled building, located along the site's eastern boundary, is partially legible. The 1917 map indicates the <br /> site as California State Hospital and shows four of the smaller buildings have been removed and the two <br /> Male Wards buildings north of Flora Street have been;altered. Four streets have been indicated.on the <br /> 1917 map. The 1950 map could not be downloaded due to technical difficulties on the website. A Station <br /> l 9 Fire Department was indicated on the southwestern corner of the site and a domicile was indicated <br /> across the street and to the east of the fire station. Sanborn Map information was acquired from an on-line <br /> source and is presented in Appendix F. <br /> 4.5 HISTORICAL USE INFORMATION FOR ADJOINING PROPERTIES <br /> Historical use information for the adjoining properties was researched using aerial photographs, historical <br /> USGS topographic maps, and the Polk City Directories at the Stockton Public Library located in <br /> Stockton, California and Sanborn Fire Insurance Maps available for the adjoining properties from.an on- <br /> 'line source. <br /> In the 1938 photograph, a farm complex with an orchard and what appear to be equipment storage areas <br /> are located <br /> adjacent to the site's eastern border and infringes within the site's eastern limits. A railroad <br /> spur appears to connect this eastern adjacent property to the railroad tracks that parallel the property's <br /> eastern boundary. A commercial complex appears to be located across and southeast from the paved and <br /> tree-€ined east-west road that is the site's southern boundary. A vacant lot with',trails and several <br /> ' buildings, and some possibly residential complexes, appear to be located directly south of the site. To the <br /> west of the site, there appear to be residences with a common driveway and a large, treed acreage area. A <br /> large complex of several buildings surrounded by open, treed acreage appears to be located north"of the <br /> site, and a road appears to separate the site from this property. The 1952 aerial photograph shows that the <br /> railroad spur, the farm complex, and most of the orchard on the adjacent eastern property have been <br /> removed, although a few rows of trees remain along the site's southeastern border. The majority,of the <br /> orchard appears to have been replaced by several long structures with an internal parking area sand a <br /> vacant area to the south. The adjacent property located south of the site's southern boundary road appears <br /> to have been filled in by an additional building and parking area to the"southeast and additional housing to <br /> the west. The road along the western border of the property has been altered; the southwestern portion of <br /> the road has been improved and developed with new structures outside the site boundary, after which the <br /> road then gently curves to the northwest away from the site. The large complex of buildings located to the <br /> north appears to have been expanded. <br /> There are no apparent changes in the 1963 and 1973 aerial photographs. The 1983 photograph was.taken <br /> at a lower altitude in comparison with the 1975 photograph, thus showing greater detail and more easily <br /> observed changes. Three buildings appear to have been added to the eastern adjacent property. The <br /> property across the road and to the southwest has been changed to support a block hof interconnecting <br /> buildings with two defined parking areas; one parking area is located in the southwestern corner of the <br /> block, and one in the northwestern corner of the block. A large building and associated parking lot <br /> appears to have been added to the land adjoining the southwestern site quadrant, north of the paved road. <br /> No other changes are apparent. <br /> USGS topographic maps from 1952, 1968, 1976, and 1987 were reviewed forthe adjacent properties. The <br /> 1952 map indicates no structures to the south of the site; these properties are shown as developed. Three <br /> structures are located on the adjacent southwestern corner. Three structures are located on the northern <br />` R <br /> i CONDOR <br />
