[ARCHIVED] City of Key West to Conduct Road Elevation Survey

City Seal

From September 18 through October 6, specialized trucks with the name “wood” on the side will be driving Key West streets, collecting LiDAR data to evaluate the city's road elevations.  LiDAR stands for Light Imaging Distance and Ranging and will enable the City to better plan, prioritize, and budget elevation projects by vastly improving its street elevation data.  The effort is part of a larger strategy to strengthen and harden the City's infrastructure and facilities in accordance with anticipated sea level rise as well as storm surge and flooding.  Staff is preparing to use the data to further stormwater, tidal, and sea level rise planning projects.

“We want the citizens of Key West to be fully informed about our efforts to protect the City and anticipate future areas of concern,” said Key West Sustainability Coordinator Alison Higgins.  “These maps are important groundwork for our upcoming Climate Adaptation Plan.” 

Wood Environmental and Infrastructure Solutions Inc. has performed LiDAR surveys for Monroe County and all other incorporated areas, working north to south.  In Key West, Wood will evaluate 72 miles of road and the first-floor elevations for critical facilities.  Wood crews will set up the control survey for Key West in mid-September by either painting or taping temporary arrow-like markings onto City streets.  These markings help the scanner match images, enabling a centimeter's accurate picture of our road elevations.
