Lodi City Landfill November 16,2011 . North of Awani Drive,Lodi,California Project No. 104690061 • The City of Lodi 3.7-acre land parcel corresponding to the Lodi City Landfill is a "penin- sula" that extends northerly into the Mokelumne River. The landfill is gated and fenced to restrict access. • The 3.7-acre site owned by the City of Lodi appeared to be secured, covered, graded, vege- tated and well maintained. • Evidence of trespassing during the site reconnaissance was observed and included transient living/camping primarily on the north side of the City of Lodi parcel, closest to the Moke- lumne River. Minor recent illegal dumping was also observed. • Wastes were observed (e.g., concrete, asphalt, glass) on the slope of the railroad bridge abutment and suggests that they may extend from the 3.7 acre City of Lodi site to beneath the elevated railroad tracks and to areas west of the tracks. • Portions of the gated residential community west of the railroad tracks (River Pointe com- munity), appear to have been constructed at locations that may have had waste disposal and/or contamination from winery/previous industrial operations. `Industrial Waste Ponds" are noted on the topographic map, historical aerial photographs indicate what appear to be surface impoundments in areas currently overlain by residences, and "waste water pond"is • noted in the WJH report for the site(WJH, 1993). • Based on the site reconnaissance and review of historical aerial photographs, there is the po- tential for the waste disposal footprint to extend west of the 3.7 acre City of Lodi Landfill (Figures 4a, 4b and 5a, 5b). • Although not known, it is possible that some residences of the gated private River Pointe community overlie areas of previous waste disposal.Based on review of aerial photographs, it is possible that if wastes were disposed of west of the tracks and north of the winery buildings that the construction of surface impoundments/waste ponds may have caused some of the ini- tially disposed wastes to have been removed and/or re-deposited. Based on review of aerial photographs and site reconnaissance, some residences northeast of the intersection of Awani and Mokelumne River Drives may be underlain by wastes. While in the field, it was decided that because of the restricted access and the potential for buried wastes at the private gated River Pointe community, available documentation pertaining to the history of the site should be obtained. Of particular interest would be information pertaining to the previous assessments and remediation of soils impacted with petroleum hydrocarbons as a result of previous use of the site as a winery, information pertaining to the former industrial waste ponds, and if possi- ble,subsurface data that may indicate the presence or absence of wastes in this area. ion6"lRSml.&c 14 f hqy *nnCE
