OBJECTIVE OF THE ONGOING PROCESS

Reduce the risk emergency shelters are facing in order to ensure the safety of the population

• Carry out a process for the prioritization of interventions (funding limitations)

• Coordinate amongst a multitude of ministries (Ministries of Local Government, Works, Education, ODM, Red Cross, etc.)

COMPONENT II: EXPOSURE AND VULNERABILITY

A) LOCATION & BUILDING CHARACTERISTICS:

• A shelter assessment is carried every year prior to the hurricane season in which all shelters are visited and structurally assessed

• Before 2013, no GPS coordinates were collected

• Before 2013, the assessment was not digitized

COMPONENT I: EXPOSURE AND VULNERABILITY

12

COMPONENT II: EXPOSURE AND VULNERABILITY

A) LOCATION & BUILDING CHARACTERISTICS:

• The surrounding topography in which the shelter is located

• The physical characteristics of the building (the number of

stories, roof type, openings, etc.)

• Floor area to house occupants during and after the event

13

B) PHYSICAL VULNERABILITY EVALUATION:

Key Components that govern building vulnerability to hurricane wind:

• The area of openings

• Shutters

• Roof cover

• Exterior wall and wall cracks

• Number of stories

• Surrounding topography (steepness of the slope)

B) PHYSICAL VULNERABILITY EVALUATION:

COMPONENT II: EXPOSURE AND VULNERABILITY

• Buildings with un-shuttered large openings AND

• metal roof in dubious condition

Worst combination of characteristics

• Buildings with un-shuttered large openings OR

• metal roof in dubious condition• Steep terrain• Multiple stories

Worse combination of characteristics

• Buildings with un-shuttered large openings OR

• metal roof in dubious condition
