Storm Damage Assessment Protocol

Storm Damage Assessment Protocol

• Data Collection and Reporting

2
Overview

• Data Collection
• Estimating Engine
• Report Means
• Storm Damage Brochure

3
Overview Pre-storm setup

• Create random sample
• Before emergency!
• Use electronic or manual means
• Measure tree density and size class
• Within ROW
• Also 50 back from ROW edge
• Take final steps
• Pre-Storm report form useful estimate
• Storage for future use

4
Overview Post-storm work

• Revisit sample segments
• Debris choose estimation method
• Indirect by average crown loss class
• 0-25, 26-50, etc.
• Loss category images available from FS
• All trees within 50 of ROW
• Direct as CY of debris
• Only trees within ROW
• Hazard pruning by size class
• Hazard removal by size class
• Enter data, report results

5
Validity from random sampling

• General discussion earlier
• Storm type factor
• Tested for ice storms
• Low variance
• 2 sample got within 5 of true value in field
  test
• Not tested for wind storms
• Larger variance
• May affect required sample size
• Area of ongoing i-Tree research

Data Collection
7
Paper forms

• In disaster work, good reason to keep paper as
  option
• Electricity not a concern
• Damage possibility minimal
• Reduces training needed
• Forms for many different situations
• In Manual, also can be downloaded from website

Spreadsheet

• Estimator built as Excel spreadsheet
• 6 worksheets
• Home/ReadMe navigation, help
• PreStorm Data setup data
• PreStorm Analysis preliminary analysis
• PostStorm Data damage data
• PostStorm Analysis report form
• Codes, lookup tables functional elements
• Use of Excel based on user survey

Procedure

• Estimation
• Starts with field data
• Uses local costs
• Scales up with simple formulas
• Calculation page report
• Credibility
• Ease, speed

20
Validation

• Sampling indicated on report
• Means of random sampling
• Percent of street miles sampled
• Numbers derived right on sheet
• Debris
• Pruning, removal
• Local costs shown

21
These values can be adjusted by end user
