Indian River County <br /> File No . 06 - 5699 - 1 - <br /> 1 . 0 INTRODUCTION <br /> 1 . 1 Site Location <br /> It is our understanding that the project limits consist of the vacant , undeveloped land west of the <br /> existing alignment of 20th Avenue SW , between 17th Place SW to the north and 25th Street SW to <br /> the south , in Indian River County , Florida . The project limits are located within Section 35 of <br /> Township 33 South , Range 39 East. <br /> The approximate project limits are shown superimposed on a reproduction of the 1949 Oslo , <br /> Florida , USGS Quadrangle map presented as Figure 1 . <br /> 1 . 2 Project Considerations <br /> Based on information provided to us by GL Homes , and on review of records available from the <br /> Indian River County Engineering Department , we understand that 201h Avenue SW currently <br /> consists of a one lane , one-way ( northbound ) , undivided rural section with stormwater run - off <br /> typically sheet flowing to adjacent grassed areas and drainage ditches . <br /> Based on our understanding and review of the " Falcon Trace Survey Control" sheets prepared for <br /> the project by Knight , McGuire & Associates , Inc . , dated April 27 , 2005 , the proposed <br /> improvements consist of constructing two new travel lanes west of the existing travel lane of 20th <br /> Avenue SW between 17th Place SW and 25th Street SW . We further understand that the proposed <br /> new centerline - of 201h Avenue SW will be approximately 28 feet west of the existing western edge <br /> of pavement of 201h Avenue SW . We have assumed that a curb-and-gutter system and stormwater <br /> pipes will direct stormwater runoff to nearby stormwater ponds and drainage ditches . <br /> 1 . 3 Purpose and Scope of Project <br /> The purposes of this project were to explore shallow subsurface conditions within the roadway <br /> improvement areas and to provide a geotechnical engineering evaluation ofethe conditions <br /> encountered . We accomplished these purposes by: <br /> 1 . Obtaining .and evaluating readily available geologic and soil survey data . <br /> 2 . Conducting auger borings at selected locations within the roadway improvement areas and <br /> measuring groundwater levels where encountered . <br /> 3 . Observing recovered soil samples in our laboratory and performing tests on selected <br /> samples to aid in classification . <br /> 4 . Analyzing and interpreting the field and laboratory data . <br /> 5 . Performing engineering analyses to develop recommendations for site preparation . <br />
