Structural Drying >> Ceiling Leak From Storm

Coastal A zones are not shown on present day Flood Insurance Rate Maps (FIRMs) or mentioned in a community's Flood Insurance Study (FIS) Report. Those maps and studies show zones VE, AE, and X (or older designations V1-30, A1-30, B, and C). Therefore, until Coastal A Zone designations Ceiling Leak From Storm or wave height contours are incorporated into Flood Insurance Studies.

The community official, designer, or owner will have to determine whether or not a site will be subject to Coastal A Zone conditions during the base flood. In order for a Coastal A Zone to be designated, Ceiling Leak From Storm two conditions are required: 1) a water depth sufficient to support waves between 1.5 and 3.0 feet high, and 2) the actual presence of wave heights between 1.5 and 3.0 feet. 

Condition 1 requires stillwater depths (vertical distance between the 100-year stillwater elevation and the ground elevation) of 2 to 4 feet at the site. Condition 2 requires wave heights at the shoreline greater than 1.5 to 3.0 feet (under the 100-year flood conditions), sufficient water depth between the shoreline and the site Ceiling Leak From Storm and few, if any obstructions (buildings, dense tree stands, etc.) that may block or dampen the waves, between the shoreline and the site. 

Figures illustrate the relationships between the stillwater flood elevation, ground elevations, associated 1 percent annual chance (100-year) stillwater flood depths, ABFEs, Ceiling Leak From Storm and associated flood hazard zones (see Hurricane Katrina Recovery Advisory Reconstruction Guidance Using Hurricane Katrina Surge Inundation and ABFE Maps).

Cross-section showing 1 percent annual chance stillwater elevation, stillwater depth and ABFE, and inland limits of V Zone and Coastal A Zone.Communities, designers, Ceiling Leak From Storm and owners can obtain the information necessary to make a post-Katrina Coastal A Zone determination by observing the site and its surroundings.

Knowing site ground elevations, Ceiling Leak From Storm and using 1 percent annual chance stillwater elevations from the Advisory Base Flood Elevation (ABFE) guidance (see Table 2). Figure 10 shows how site and surrounding conditions would influence a Coastal A Zone determination.Table 2. Updated 1 Percent Annual Chance (100-Year)

Although the site on the left is mapped Zone AE, proximity to the Gulf of Mexico shoreline Ceiling Leak From Storm and limited obstructions to waves indicate the site could be classified as a Coastal A Zone. The site on the right is over 4,000 feet from the Gulf shoreline and over 1,000 feet from the bayou, mapped as Zone AE, and has a base flood stillwater level sufficient to support >1.5-foot wave heights.

Obstructions to waves (e.g., trees and other buildings between the site and the shoreline), Ceiling Leak From Storm and distance from the sources of flooding would indicate the area is not a Coastal A Zone. The ABC's of Returning to Flooded Buildings Hurricane Katrina Recovery Advisory FEMA October 2005

Hurricane Katrina produced widespread flooding from both storm surge and levee breaches. The combination of water intrusion and delayed re-entry due to evacuation requirements Ceiling Leak From Storm and power interruption has created a situation that demands careful planning by individuals returning to flood damaged buildings. The following tips are designed to assist impacted individuals when they are able to reach their flooded property. 

Additional information can be found in the Hurricane Katrina Recovery Advisory, Ceiling Leak From Storm Initial Restoration for Flooded Buildings.Anticipate what you will need Personal protective equipment including safety shoes or boots (rubber boots may be best if you are not sure if the water has been pumped out), work gloves, eye protection, rubber gloves for cleaning.

When using sanitizing chemicals, a hard hat, and respiratory protection in case there is mold or bacteria contamination (respirators with HEPA cartridges Ceiling Leak From Storm or dust masks with a rating of N-95 or higher should be used). These can be obtained from hardware stores or home improvement stores. 

If materials containing asbestos are suspected, it will be necessary to use a respirator with a HEPA cartridge in accordance with Federal requirements.Tools for entry Ceiling Leak From Storm and cleaning such as a pry bar, shovel, and a flashlight with extra batteries (Figure 1)Camera or video recorder for recording conditions for use in insurance claims

Hand and face cleaning supplies such as alcohol swabs or hand sanitizer gelCleaning supplies for salvagable materials including potable water, chemical cleaners/sanitizers, sponges, buckets, Ceiling Leak From Storm and wiping ragsPacking supplies to protect fragile salvaged items during transportFirst aid kit

Pen and paper, tape, scissors, and small plastic storage bags for writing down serial numbers and saving samples of discarded materials to support insurance claims Be realistic about your limitations Even initial assessment and salvage can be hot, Ceiling Leak From Storm heavy work.If at all possible, work with another person while in the house. Unforeseen hazards can exist, so having help nearby is prudent.

Avoid entry, even with personal protective equipment, if you have serious pre-existing health issues: -Asthma/allergies -Heart problems -Compromised immune system -Open cuts or wounds Get help moving large items such as furniture and appliances.Do not underestimate the impact of psychological shock Ceiling Leak From Storm and physical effort: 

Identify someone in advance who you can talk to about your situation and feelings -See the resource section for some potential contacts Check the situation for hazards Downed power lines Gas leaks Evidence of structural damage such as sagging ceilings, large wall or floor cracks, Ceiling Leak From Storm walls out of plumb, etc.

Unstable materials -Furniture and even vehicles can be stacked in hazardous positions (Figure 2)Figure 2 caption. Furniture stacked by flood waters creates a safety hazard. [end caption]Chemical spills -Paints, solvents, lawn fertilizers, pesticides Vermin such as snakes, rats, fire ants, bee colonies, Ceiling Leak From Storm etc. Other hazards -Rotting food -Dead animals Document conditions

Photos or Ceiling Leak From Storm videos are best -Shoot multiple pictures of each room from different corners -Make sure the photos will be clear before changing the conditions -Use a camera with a time/date stamp for photos if possibleMake written notes of the dates that you were at the buildingSave samples of high-quality contents such as carpets to support insurance claimsExtract the salvageable items
