Summary
This tool uses the Target Hazard Value tool to calculate the weighted hazard score for each of the hazard criteria (fire flow, occupancy type, life safety, building height, building area, and economic impact). This tool then sums these values to calculate the total hazard value for the property.
Usage
- Use the Populate Hazard Criteria tool to calculate the fire flow, occupancy type, life safety, building height, building area, and economic impact of each property.
- To compute a meaningful target hazard value, the sum of the weights of the criteria should be 100.
- This tool assumes the structure of the Target Hazard feature class is consistent with the feature class provided in the Local Government Information Model. To use alternate fields, edit the model.
Parameters
| Parameter | Explanation | Data Type |
| Target Hazard Feature Class | Feature class used to assess the target hazard value of a property | Feature Layer |
| Fire Flow Spreadsheet | Excel spreadsheet containing a numeric classification of ranges of fire flow values. Fire flow ranges are inclusive, and the upper and lower values must be separated by a dash (-). | Table |
| Fire Flow Weight | Value from 0 through 100 representing the importance of fire flow relative to the other criteria used to calculate the target hazard value. | Long |
| Occupancy Type Spreadsheet | Excel spreadsheet containing a numeric classification of occupancy types. Occupancy types may be: An inclusive range of values separated by a dash (-), for example, 3-5, or A comma-separated list of values, for example, Utility, Storage |
Table |
| Occupancy Type Weight | Value from 0 through 100 representing the importance of occupancy type relative to the other criteria used to calculate the target hazard value. | Long |
| Life Safety Spreadsheet | Excel spreadsheet containing a numeric classification of life safety types. Life safety types may be: An inclusive range of values separated by a dash (-), for example, 3-5, or A comma-separated list of values, for example, Utility, Storage |
Table |
| Life Safety Weight | Value from 0 through 100 representing the importance of life safety relative to the other criteria used to calculate the target hazard value. | Long |
| Building Area Spreadsheet | Excel spreadsheet containing a numeric classification of ranges of building areas. Building area ranges are inclusive, and the upper and lower values must be separated by a dash (-). | Table |
| Building Area Weight | Value from 0 through 100 representing the importance of building area relative to the other criteria used to calculate the target hazard value. | Long |
| Building Height Spreadsheet | Excel spreadsheet containing a numeric classification of ranges of building heights. Building height ranges are inclusive, and the upper and lower values must be separated by a dash (-). | Table |
| Building Height Weight | Value from 0 through 100 representing the importance of building height relative to the other criteria used to calculate the target hazard value. | Long |
| Economic Impact Spreadsheet | Excel spreadsheet containing a numeric classification of ranges of the economic impact of the property. Economic impact ranges are inclusive, and the upper and lower values must be separated by a dash (-). | Table |
| Economic Impact Weight | Value from 0 through 100 representing the importance of economic impact relative to the other criteria used to calculate the target hazard value. | Long |
