Background InformationMy name is David Renna. I am a GIS Analyst hired by Florida Power

& Light Company to analyze a proposed new transmission line.The Bobwhite – Manatee Transmission line is to cover a corridor

just to the Southeast of Tampa/St. Petersburg area.This project began back in the Spring 2006 and is set for

completion in late 2011.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.

I have included a timeline of the project in order to let you get familiar Florida Power & Light’s plans.

This is analysis directly related to concerns of clients to which letters were sent out.

Project Timeline

Proposed Bobwhite –Manatee Project Study Area

•13 sites considered.•Transmission line route crossing Manatee and Sarasota county lines•Energy source located in Manatee County.•Line runs south approximately 25 miles(52 miles total).•End in Sarasota county at new proposed substation.•Public Concerns Analysis over two year period from Spring 2006 – 2008.

Critical Public Concerns Addressed1. Conservation Areas Preserved2. Wetlands Preserved3. Homes affected during construction4. Number of county parcels affected during

project5. Schools and Daycare within corridor6. Construction Cost kept to minimum

Conservation Areas

•Nine Conservation Areas within study area•Only three conservation areas affected1. Lake Manatee Lower

Watershed (5796 Acres).2. Lake Manatee State Park

(549 Acres).3. Heritage Ranch

Conservation Easement (1972 Acres)

• Lines do not cross over Conservation areas.

• Run tangent along conservation area boundaries.

• Very little affect on proposed project

Wetlands Affected

Total AreaToal WetlandsTotal DrylandsAffected Wetlands

• 3403 total wetland areas•Total Area: 137719.85 Acres•Wetland Acres: 19053.94 12%•Dryland Acres: 118665.91 88%•Affected Wetlands Acres: 398.14 <1%

Individual Homes Affected

•Approximately 70 total homes affected.•23 inside transmission line corridor.•47 within 400 ft buffer of corridor.•Most of area used for farm land.

County Parcels Affected Manatee/Sarasota Counties•12360 total parcels within study area•255 Total parcels affected.•202 parcels in Manatee County•53 parcels in Sarasota County•33 parcels contained within 400 ft buffer zone.•222 parcels affected by intersection by transmission line•.02 % of total parcels affected

Schools and Daycares Manatee/Sarasota Counties•No schools or daycares within 400 ft. of transmission line.•1 school within half mile (Robert Wells Elementary: Manatee County)•2 Daycares within half mile 1. Sprouts Child

Development Center2. Children of Faith Child

Development Center• All schools and daycare

within half mile of line are located in SW region of study area.

Soil CharacteristicsBobwhite – Manatee Line

•FS = Fine Sand•LFS = Light Fine Sand•MK-FS = Muck/Fine Sand•Muck= Muck

•Notice yellow shades in NW and SE Region of study area.•Yellow regions show areas of soil composition not suitable for construction (Muck)

Cost AnalysisTransmission line length = approximately 52

milesCost of installing a Single Circuit Tubular

Steel Pole 230KW transmission line = approx. $57 million

Cost of tying line into grid at each end of transmission = $2.3 million

Total Estimated Cost (TEC)= $62 million

Conclusion: Bobwhite-Manatee Transmission ProjectOverall concerns have been addressed. Proposed

site seems to fit all criteria.Conservation areas and wetlands are not

affected.Number of homes affected is lowNumber of property parcels affected is very low

percentage of total parcelsNo schools or daycares are affectedConstruction cost are reasonableObjectives complete: Transmission of power to
