Bobwhite-Manatee Transmission Line Project

Background Phase

Arbor Day Foundation

Project Goals and Objectives• Goal: Select optimal

transmission line route based on four primary factors:• Proximity to schools and

daycares• Environmental impact• Proximity to individual homes

and land parcels• Length and cost of line

Study Area and Data• Role of GIS •Manatee and Sarasota Co.• Basemap layers• Data needs• Data acquisition and source• Data limitations

Cartographic Model• Defines goals and objectives• Broken down by criteria• Lists data requirements• Lists GIS approaches and

tools• Illustrates feedback loops,

including public comment

Analysis and Results Phase

Arbor Day Foundation

Environmental Analysis•Minimize impact• Study area location• Impacted conservation lands• Impacted uplands• Impacted wetlands• GIS process and tools• Other potential analysis

Schools and Daycare• Research on adverse effects

on children• Avoid locating line within

400ft• GIS process and tools• No schools or daycares

within 400ft of line

Impacted Homes•Minimize impact• Balancing act• 20 houses within corridor• 26 houses within 400 Ft.

buffer•Most homes along current

lines and right-of-ways

Impacted Parcels•Minimize number impacted• Future value• Current land uses• GIS processes and tools• 162 within corridor• 93 within buffer

Estimated Line Length• Use of existing Roads•Manatee River/Lake• Engineering/cost related to

line length• Estimated length = 24.5 • Cost per mile

Conclusion•Were overall goals and objectives met?•Balancing the four criteria•Community participation and buy-in•Conservation opportunities•Additional capabilities•Role of GIS and ArcMap software
