|
|
Making changes to an existing building to protect it from flooding or other hazards such as high winds and earthquakes. |
|
|
Changing the appearance of your house to fit the neighborhood. |

Storm surge is: |
|
|
High winds associated with hurricanes |
|
|
The rise in the level of the ocean that results from the decrease in atmospheric pressure associated with hurricanes and other storms. |
|
|
High winds associated with tornadoes. |

In Fig 2.6 the 100-year flood elevation for the house shown is 391.6 feet. According to survey the elevation of the lowest floor of the house is 389.3 feet. The flood depth above the lowest floor is therefore equal to: |
|
|
2.3 feet during the 100-year flood. |
|
|
7.8 feet any time it rains and flood the area |
|
|
10.1 feet during the 100-year flood |
| 5. |
In fig 2-7; during a flood hydrostatic pressure acts on walls and the bouncy force pushes against slab from underneath. In homes with a basement, saturated soils add to the pressure on basement walls and concrete slab. |

According to table 3-2 the cost of elevating a frame house 2 feet off the ground on Slab-on-grade foundation is approximately: |
|
|
$47.00 ft.2 |
|
|
$17.00 ft.2 |
|
|
$35.00 ft.2 |
| 7. |
Wet flood proofing a house is modifying |
|
|
A house against the rain |
|
|
The uninhibited section of the house such as crawlspace or unfinished basement so that the flood waters will enter but not cause significant damage to either the house or its contents. |
| 8. |
Fig 3.7 and 3.8 show two examples of wet floodproof house. The purpose of allowing water enter into portions of the house is to ensure that the interior and exterior hydrostatic pressure on the walls will be equal. |
|
|
True |
|
|
False |
| 9. |
According to table 3.4, the cost of wet flood proofing a masonry house up to 8 ft above the ground/basement floor with a basement foundation is : |
|
|
$1.70 ft.2 |
|
|
$3.50 ft.2 |
|
|
$10.00 ft.2 |

Dry floodproffing is completely sealing the exterior of a building to prevent the entry of floodwaters. Successful dry flood proofing involves which one of the following: |
|
|
Sealing the exterior walls of the house |
|
|
Covering openings bellow the flood level |
|
|
Protecting interior of the house from seepage |
|
|
Protecting service equipment outside the house |
|
|
All of the above |
