Building Safe Communities - From the Ground Up

- by Clifford Oliver, CBCP

Hurricanes, tornadoes, floods, wildfires, earthquakes -- rural communities hit by natural disasters are often the hardest hit. The impact on individuals can be devastating, with significant loss of property and even lives.

Severe weather can affect all communities whether large or small, rural or urban. The fact is, regardless of what type of natural disaster threatens a community, creating a disaster-resistant community is possible by incorporating prevention as part of the planning process. Building new structures or enhancing existing structures is a key component in reducing the potential damage that may result when a disaster hits a community. And it’s been proven - prevention works!

The Federal Emergency Management Agency (FEMA) estimates that every dollar spent on disaster prevention efforts yields two dollars saved in repairing damage caused when a disaster hits. Through FEMA’s Project Impact, an initiative to make America’s communities disaster resistant, the agency encourages local community officials, businesses and residents - including developers - to take responsibility for preparing their communities to safely weather a disaster.

Against the Wind
The high-speed winds and airborne debris that come with tornadoes and hurricanes can cause extensive damage to homes and buildings, and threaten the lives of those inside. The residents of Tulsa, Oklahoma know this all too well. The community has been hit by several powerful and damaging tornadoes in the past. As a partner with FEMA’s Project Impact, the Home Builders Association of Greater Tulsa (HBA) has played an instrumental role in planning for and installing safe rooms in Tulsa residences and informing the community about their importance.

Safe rooms are hardened structures, often built of concrete, built within a home or public building that provide a ‘safe-place’ people can go to during severe weather to survive with little or no injury. Safe rooms are designed to withstand winds of up to 250 miles per hour, particularly important in tornado prone areas where most building code requirements for high winds are set significantly lower than the wind speeds typically associated with a tornado or hurricane.

Recognizing the importance of these structures, several of Tulsa’s HBA members are incorporating prevention measures into the initial design of the homes and including safe rooms as a standard feature in housing communities under construction in that region.

Rising Waters
With wind speeds of at least 74 miles per hour and rapidly rising surf, hurricanes pound coastal areas with a one-two punch of damage. Kenny and Diane Gregory’s Virginia Beach, Va. house stood up to the test-literally. After Hurricane Bonnie dropped a tree through the roof of their home just three days before the closing date, the Gregory’s decided to start from scratch and build a new, disaster-resistant home. The Gregory’s new house is now an additional 16 inches off the ground for additional flood protection that proved valuable after hurricane Floyd hit last September.

Innovations in design and the demands of homeowners encourage contractors build homes like the Gregory’s. In addition, the foresight of builders to offer safer, more disaster-resistant homes at the outset will help communities minimize the damage from a flood or rising waters from a hurricane.

Elevating structures in hurricane and flood prone areas is only one way builders and community planners can ensure homes are disaster resistant. Others include:
 Building homes and business on higher ground so they remain above the flood plain when inclement weather strikes.
 Constructing homes and public buildings on sturdy foundations and taking precautions to ensure that those foundations will not settle or sink if flooding occurs.
 Making provisions during the planning stages for fuse boxes, ventilating, heating and cooling equipment to be elevated above ground level to reduce the risk of electrical failure and danger from electric circuits.

On a Fault
Reviewing where a home or business will be located is one of the first steps to making a home disaster resistant. In recent years, there is a better understanding of the seismic threat in the U.S. Many parts of the country have recently been identified as having a higher seismic threat than previously thought, making earthquakes more than “just” a West Coast problem.

Whether in a rural or urban area, the best protection for homes in earthquake prone areas is to brace structures for the seismic shifts that might occur. Bolting wood frame houses to concrete foundations can avoid pulling apart if an earthquake hits. For structures with tile roofs, use of mechanical fastening ensures the tiles will not slide off and become falling debris.

Additionally, all major appliances and heavy objects should be securely attached to a supporting wall. Anchoring heavy furniture also eliminates the danger of shifting and falling objects. Shatter-resistant glass, especially when used in entranceways or other escape routes, protects residents from being injured from cracked and broken glass.
Finally, a thorough structural inspection of buildings and necessary repairs helps to ensure that safe buildings stay safe and can vastly reduce the amount of damage caused by earthquakes.

Snuffing out the Flames
After one of the worst wildfire seasons in history, people in rural areas are well aware of the massive destruction fires can wreak. Wildfires usually occur in areas with a high concentration of dry vegetation and areas that often have seasons of drought combined with high temperatures. While these are considered ideal conditions, wildfires can erupt under other conditions as well.
Instituting safety precautions when building can reduce the danger of wildfires. Ideally, buildings developed in fire-prone areas will be built using flame-retardant materials. However, protecting homes and businesses can also mean building within, or creating, a 25’ safety zone separating them from all combustible vegetation. This zone reduces the spread of fires by eliminating their fuel and keeping them away from buildings.

Taking Action
Acknowledging that natural disasters occur in all regions of the United States is the first step in creating disaster resistant communities. Determine what type of disaster poses the greatest risk to your community, then build smarter such that homes and buildings can withstand a variety of disasters. By thinking about disaster resistance in the planning stages, you have the power to make a difference.
