If such data is not reasonably ascertainable,it may be necessary to rely on other <br /> sources of i <br /> nforM2tion,:such as surface topographic information,hydrologic information,hydrogeologic data <br /> collected on nearby prp:perties,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�l 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 /> TARGET PROPERTY TOPOGRAPHY <br /> USGS Topographic Map: 2438121-B1 CLEMENTS, CA <br /> General Topographic Gradient: General NW lY <br /> Source: USGS 7.5 min quad index <br /> SURROUNDING TOPOGRAPHY:ELEVATION PROFILES <br /> o 11 <br /> Ca <br /> W <br /> North South <br /> TIP <br /> J <br /> it <br /> Z. <br /> 2!- <br /> IiS <br /> West i East q <br /> TP <br /> 0 112 1 Miles <br /> Target Property Elevation: 13.9 ft. <br /> ih <br /> Source:Topography has been determined from the USGS 7.5' Digital Elevation Model and should be evaluated. <br /> on a relative(not an absolute)basis.
