Slide1: 

Overview of the FEMA Tornado BCA Module

Tornado Mitigation Projects: 

Tornado Mitigation Projects The primary impacts (or damages) are injuries and casualties The most common type of project involves shelters or safe-rooms for life-safety

Tornado Mitigation Projects (continued): 

Tornado Mitigation Projects (continued) Lack of warning time requires that the: Shelter MUST be very close to the residents or occupants. Shelter occupancy (sq ft / person) is less than for a hurricane shelter (due to shorter time of sustained high winds)

BCA Module Installation: 

BCA Module Installation Open the “Read Me First!” file (found in: BCA Software and Technical Manuals / BCA Tornado folder on the FEMA 2003 Mitigation BCA Toolkit CD) Installation for different Windows platforms (a) Windows 3.1, 95, & 98 (b) Windows 2000 and later

Data Entry: 

Data Entry The current module is for both Tornado and Hurricane shelter mitigation measures – users need to select the hazard-specific features throughout the data entry process

Data Entry (continued): 

Data Entry (continued) MUST have state and county selected on the Project Descriptive Information screen (to activate the historical tornado data) Requires data from the building footprint – longest length and longest width

Data Entry (continued): 

Data Entry (continued) Note 1: The “shelter area” is usually smaller than the normal “occupancy area”: Shelter Area: area set aside for the shelter protection project within the building Occupancy Area: usable area of the entire building

Data Entry (continued): 

Data Entry (continued) Note 2: Average shelter areas per person are different for hurricane and tornado shelters: Tornado: 5 sq ft / person Hurricane: 10 sq ft / person

Data Entry (continued): 

Data Entry (continued) Use the updated (2004) values for: Minor injury: $1,705 Major injury: $17,047 Death: $2.96m
