GEOGHEC# ' = PHYSICALS"�TTlNG,SOURGE SUMMARY <br /> GROUNDWATER FLOW DIRECTION INFORMATION <br /> Groundwater flow direction for a particular site is best determined by a qualified environmental professional <br /> using site-specific well data.If such data is not reasonably ascertainable,it may be necessary to rely on other <br /> sources of information,such as surface topographic information,hydrologic information,hydrogeologic data <br /> collected on nearby properties,and regional groundwater flow information(from deep aquifers). <br /> TOPOGRAPHIC INFORMATION <br /> Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to <br /> assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, <br /> should contamination exist on the target property,what downgradient sites might be impacted. <br /> USGS TOPOGRAPHIC MAP ASSOCIATED WITH THIS SITE <br /> Target Property: 2438121-A4 TERMINOUS,CA <br /> Source:USGS 7.5 min quad index <br /> GENERAL TOPOGRAPHIC GRADIENT AT TARGET PROPERTY <br /> Target Property. General SW <br /> Source:General Topographic Gradient has been determined from the USGS 1 Degree Digital Elevation Model and <br /> should be evaluated on a relative(not an absolute)basis.Relative elevation information between sites of <br /> close proximity should be field verified. <br /> HYDROLOGIC INFORMATION <br /> Surface water can act as a hydrologic barrier to groundwater flow. Such hydrologic information can be used to assist <br /> the environmental professional in forming an opinion about the impact of nearby contaminated properties or,should <br /> contamination exist on the target property,what downgradient sites might be impacted. <br /> Refer to the Physical Setting Source Map following this summary for hydrologic information(major waterways <br /> and bodies of water). <br /> FEMA FLOOD ZONE <br /> FEMA 03 Flood <br /> Target ProCounty Data Electronic Cove�e <br /> SAN JOAQUIN,CA YES <br /> Flood Plain Panel at Target Property: 060299026081 CBPP <br /> Additional Panels in search area: 0602990120B 1 CBPP <br /> 0602990140B I CBPP <br /> 060299028081 CBPP <br /> NATIONAL WETLAND INVENTORY <br /> NWI Electronic <br /> NWI Quad at Ta et Prope Coverage <br /> k <br /> TERMINOUS YES <br /> f <br /> HYDROGEOLOGIC INFORMATION <br /> Hydrogeologic information obtained by.installation of wells on a specific site can often be an indicator <br /> of groundwater flow direction in the immediate area.
