_ 1 KLE/NFELDER a„9n, Bowe. a;9n«auvom 1 . Norman 's Nursery is located in a rural area of San Joaquin County, east of the City of Linden , California . The site is bordered on the north by Potter Creek, on the west by Escalon Bellota Road , and on the east and south by hills used for cattle grazing . The nursery property totals approximately 450 acres of land of which approximately 200 acres are used for production of trees and shrubs. Nursery stock is in 1 -gallon cans to large box trees . Approximately 95 percent of the production acreage is drip irrigated . Irrigation water used on site for nursery production purposes has been injected with a liquid fertilizer mix. 2 . The production area of the nursery exists at an elevation of approximately 125 feet msl . A survey of the property, including some topography is underway, but was unavailable by the production date of this report. According to the U . S . G . S . topographic map for the area , an intermittent stream and numerous drainages appear to flow across the Norman's Nursery site. According to the U . S . D .A. soil survey for the area , the near-surface soil on the nursery property and the adjacent Barbagelata orchard is unsuitable or poorly suited for hardwood trees . 3. According to the Fall 1996 Groundwater Report by the San Joaquin Flood Control and Water Conservation District, groundwater beneath the Norman's Nursery site exists at a depth of approximately 150 to 160 feet (elevation of - 28 to -28 feet msl) and flows towards the southwest. According to the U . S . D .A, soil survey perched water conditions may exist in the area. Perched water conditions were encountered by Kleinfelder during the installation of Monitoring Well MW-2 (upslope from the nursery operations , to the east) and in Monitoring Well MW-5 downslope of nursery operations , near the northwest corner of the property) . Perched water existed at a depth of approximately 5 feet (within and above a gravel stratum) in both borings . The gravel stratum is underlain by a sandy clay/clayey sand layer. 4 . Perched groundwater was not detected in Monitoring Well MW-4 adjacent to Basin B . Because of the lack of water present at that location , and the concerns expressed by third parties over potential percolation of water from the pond , a double-nested monitoring well was constructed in the location (Monitoring Well MW-4D and MW-4S) . 5. Six soil borings were advanced in mid-December 1997 on the Norman's Nursery property. Perched groundwater was encountered in two of the six boring locations (B-2/MW-2 and B-5/MW-5) . Perched water was not encountered in the other four borings. However, a double-nested monitoring well (MW-4S and MW-4D) was installed adjacent to the north side of Basin B . 6 . Soil beneath the site can be very generally summarized as a clayey gravel (with an inconsistently present 2-foot thick interbedded layer of sandy clay or clayey sand present to a depth of approximately 17 feet) . The clayey gravel is generally underlain by an approximately 5- 10 foot thick layer of silt or clayey silt. The silt layer is underlain by silty sand which may contain interbedded layers of clay or clayey silt. 117226.E021STO13R0176 Page 8 of 40 January 31 , 2013 Copyright 2013 Kleinfelder
