2004 -2005 Hurricanes Do you have a plan?
What is i-Tree Storms n Spreadsheet-based interactive tool ¨ Pre-storm analysis for planning purposes Tree removal and pruning hours and costs n Debris amounts and hauling costs n Potential based on number of trees and size per total street miles n ¨ Post-storm analysis Estimation of number of trees needing to be removed and pruned and hourly estimates n Estimation of debris volume and costs to haul n
What is i-Tree Storms Originally designed for ice storm debris n Debris generated by ice differs from wind n ¨ Ice – debris falls straight down / no C&D ¨ Wind – debris carries and not just vegetative n i-Tree Storms Hurricane adaptation ¨ Currently in beta testing ¨ Initiated by Escabedo and Marcus ¨ Uses real debris data from real FL cities
What is i-Tree Storms n Uses randomly selected street segments ¨ For tree counts by size class ¨ For debris volume estimates n Data collection ¨ Paper ¨ PDA n Calculations ¨ By hand using the supplied data sheets ¨ Excel spreadsheet template
Basic Steps in Developing an i-Tree Storms Project n Preliminary information n Creating the project in i-Tree Storms n Collecting field data n Transferring data to template n Communicate results
Basic Steps in Developing an i-Tree Storms Project n Preliminary information n Creating the project in i-Tree Storms n Collecting field data n Transferring data to template n Communicate results
Preliminary Information n ID your area of interest ¨ Region ¨ County ¨ City n Stratify area ? ¨ Residential ¨ Commercial ¨ Industrial
Preliminary Information Isolate affected area using GIS layer or paper map Stratify into land-use areas (i. e. residential, commercial, industrial, etc. ) if needed Randomly choose 10 -30 street segments from each stratum Obtain length of each street segment (ft) and total street miles in affected area
Preliminary Information n Pre-storm data collection ? ¨ Debris potential ¨ Potential clean up costs ¨ Development of storm plan n Who and How will data be collected? ¨ In-house n or contracted out Volunteer labor from tree boards? ¨ Paper or electronic (PDA)
Preliminary Information n Estimate time needed for pruning/removal ¨ By size class ¨ Storms uses default values if unknown Estimate cost of debris hauling per yard n Estimate hourly rates n ¨ Removals ¨ Pruning n Contractors will have this information

Creating the Project in i-Tree Storms n User’s Manual can be found ¨ C: Program Filesi-TreeSTORM ¨ i-Tree. Users. Manual_STORM. pdf n Create a new project for each stratum ¨ Save data in separate files St_Augustine_residential. xls n St_Augustine_commercial. xls n St_Augustine_industrial. xls n

Collecting Field Data n Tools to take in field ¨ Map of street segments ¨ Paper n data sheets One for each segment ¨ Clip board ¨ Biltmore or d-tape n For eye calibration ¨ Pencils

Communicating Results Now What?
Communicating Results n Present estimates to Mayor, City Council, City Manager ¨ Emphasize the need for a storm plan Temporary debris storage facilities n Develop storm fund reserves for clean up n n Find which departments have storm plans ¨ Where n do trees fit into those plans? Talk with county EMA about a storm plan ¨ Potential debris volume
