Storm Damage Assessment Protocol

Analysis and Reporting


Overview l.jpg
Overview

  • Estimating Engine

  • Report Means

  • Resources


Estimating engine l.jpg
Estimating engine

  • Engine 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 l.jpg
Procedure

  • Methods I

    • Starts with field data

    • Simple scaling by street miles

    • Relies on sample size being sufficient for damage variance

    • No statistics applied for emergency use


Procedure6 l.jpg
Procedure

  • Methods II

    • Pruning, removals: straightforward

    • Debris: depends

      • Pre-storm data

        • Uses calculated tree density

      • No pre-storm data

        • Uses estimated tree density (Very low, Low, etc.)

        • Based on data from 13 Northeastern communities

    • Local costs used, tho averages suggested



Report l.jpg
Report

  • = Calculation page (PostAnalysis tab)

  • Methods visible

  • Advantages

    • Credibility

    • Ease, speed



Validation l.jpg
Validation

  • Sampling indicated on report

    • Means of random sampling

    • Percent street miles sampled

  • Numbers derived right on sheet

    • Debris

    • Pruning, removal

  • Local costs shown

Future l.jpg
Future

  • Wish list

    • Add 6-mo. damage inventory

      • Tree-by-tree

      • Inspired by FS method after Katrina

    • Convert to single VB app

    • Integrate with STRATUM

  • Will depend on available time and money
