  2. 2. Background Information<br />My name is David Renna. I am a GIS Analyst hired by Florida Power & Light Company to analyze a proposed new transmission line.<br />The Bobwhite – Manatee Transmission line is to cover a corridor just to the Southeast of Tampa/St. Petersburg area.<br />This project began back in the Spring 2006 and is set for completion in late 2011.<br />Letters were sent out in November 2006 to provide needed information to customers who were going to be affected by the construction of the new transmission line. These letters were also to find out some of the concerns of property owners affected by project.<br />I have included a timeline of the project in order to let you get familiar Florida Power & Light’s plans.<br />This is analysis directly related to concerns of clients to which letters were sent out. <br />

  32. 32. Notice yellow shades in NW and SE Region of study area.
  33. 33. Yellow regions show areas of soil composition not suitable for construction (Muck)</li></li></ul><li>Cost Analysis<br />Transmission line length = approximately 52 miles<br />Cost of installing a Single Circuit Tubular Steel Pole 230KW transmission line = approx. $57 million<br />Cost of tying line into grid at each end of transmission = $2.3 million<br />Total Estimated Cost (TEC)= $62 million<br />
  34. 34. Conclusion: Bobwhite-Manatee Transmission Project<br />Overall concerns have been addressed. Proposed site seems to fit all criteria.<br />Conservation areas and wetlands are not affected.<br />Number of homes affected is low<br />Number of property parcels affected is very low percentage of total parcels<br />No schools or daycares are affected<br />Construction cost are reasonable<br />Objectives complete: Transmission of power to Sarasota County <br />
