1 0 • <br /> ' 3.1.2 Adjacent Properties <br /> The area known as the Gleason Park Neighborhood (named for the public park located <br /> immediately north of the Site) has been a middle to lower socio-economic neighborhood <br /> since the early 1900's. The neighborhood is bordered on the south by Mormon Slough <br /> ' which flooded several years in a row around the beginning of the 1900's. In 1911,these <br /> floods were contained by a newly constructed diverting canal (Jones and Stokes,2005). <br /> As determined from the Sanborn Fire Maps,the block to the north of the Site on which <br /> Gleason Park is now located was partially filled with residential homes in 1895. By <br /> 1917,Lafayette Grammar School had been built in the southeast comer along with <br /> ' several new homes. To make way for the school,at least 5 other residential structures <br /> were removed. By 1950,all the houses on the block had been removed except one. The <br /> 1972 United States Geological Services Topographical Map labels the school as vacant <br /> and the remaining home on the block is not pictured.The demolition date of the school is <br /> unknown. The city block was vacant and used as a city park until 1995. <br /> ' The City of Stockton added public sewers and water mains to the area in the 1910's. <br /> Subsequent use of the windmills and associated water wells and tanks was eliminated <br /> thereafter. The 1917 Sanborn Fire Maps do not show the windmills or associated tanks <br /> ' on the maps. <br /> The adjacent properties contain numerous windmills with tanks. See Table 1 below. All <br /> ' of these wells are again absent from the 1917 maps. Their current existence or <br /> destruction status is unknown. <br /> Table 2: Adjacent 1895 Prope Water Wells <br /> Sanborn Maps Block# Number of Wells Direction from Site <br /> 233 1 Northwest <br /> 232 (Gleason Park) 1 North <br /> 231 3 Northeast <br /> ' 264 1 East <br /> 575 0 Southeast <br /> 574 0 South <br /> 573 0 Southwest <br /> 262 5 West <br /> Total 11 <br /> ' 3.2 Hazardous Substance/Waste Management Information <br /> 3.2.1 The Site <br /> A Phase I Environmental Site Assessment(Phase I) was completed by Aperio Inc. titled <br /> ' Phase I Environmental Site Assessment, Proposed Spanos Elementary School Site, dated <br /> May 16, 2005 previously submitted to the DTSC.
