TEMPORARY KING TIDE FLOOD CONTROL BARRIERS TESTED IN KEY LARGO’S TWIN LAKES AREA

KEY LARGO, FL – Monroe County is testing a temporary flood control barrier in the Twin Lakes community in Key Largo to help alleviate recent king tide road flooding. As one of the County’s pilot road elevation projects not yet constructed, this interim measure will provide relief to residents from the current tidal flooding.

On Friday, Oct. 2, temporary 24-inch high water-filled flood control barriers were installed by County staff and the vendor, U.S. Flood Control. The barrier provides a dam between the road and the tidal waters of Florida Bay. The barrier did contain the rainwater that fell last weekend on the road, but Monroe County Roads Department staff pumped the freshwater off the road once it stopped raining.

“This isn’t a permanent fix, but as of today, the barrier has been successful in holding back the high king tides from entering the road in all but one low-lying area where seawater was seen bubbling up through the ground near the road,” said Monroe County Engineering Services Director Judy Clarke. “We are in the process of securing additional barriers for neighboring Stillwright Point, and we hope to have them installed as soon as possible.”

After reviewing the Stillwright Point area, the barriers will provide a temporary solution to tidal flooding at the entrance of that community.

The barriers can be used during king tide season, which typically runs September through November and again in the spring, and then removed once the king tides or extreme high tides no longer cause roadway flooding. Once removed, they can be stored and refilled and reused the next season or in other areas.

U.S. Flood Control Barrier

Being Prepared for Flooding is More than Half the Battle.

Prepared for Flooding

A good flood protection strategy can not only save millions when it comes to cities and municipalities but it also saves residential property and lives.

U.S. Flood Control and Tiger Dam™ work with cities, municipalities and home owners not only to protect their citizens and property but to help them develop effective strategies to stop flooding from Hurricane, Storms Surges, Overflowing Rivers, Melting Snow and Ice and much more.

U. S. Flood Control provides direction for a good flood prevention plan and supplies training courses for large cities, towns, large properties and individual properties such as at-risk, low laying neighborhoods, standalone box stores like Walmart, Power Stations and Schools.

Tiger Dams can protect and act as:

  • Homeland Security
    The Tiger Dam™ system may be able to contain spilled bio-hazardous materials, wastewater and terrorist intended chemical liquids. The 90 second rapid deployment diversion Tiger Dam™ weighs 65 lbs. when empty, can be immediately filled to 50 feet holding 6300 lbs. of chemical liquid or slurry type mixtures. Simply use a 2″ pump to pump the sand/debris into the tube. The tube becomes an airtight holding tank, with over 6000 lbs. capacity –remove as weight capacity changes with the density of what it is filled with. Once contained in the holding tank, the spill can be pumped out at a safe and convenient time into a bio-hazardous tank truck/water truck and disposed of according to environmental standards.
  • Retention Ponds
    The Tiger Dam™ system can be used as an alternative to reduce the number of acres required for storm water retention and the costs associated with excavating and removing fill material from subdivisions.

  • Telephone, Fiber Optics, Hydro Dams and Utilities
    The Tiger Dam™ system can replace the use of sandbags and crews needed to man the sandbag walls to protect the utility and the employees in a time of flooding.See Tiger Dams Jackson Mississippi » https://bit.ly/2S0Qyhj
  • Chemical Plants / HAZMAT
    The Tiger Dam™ system can be used as containment or secondary containment to mitigate spills versus expensive earth works and containment membranes.
    The Tiger Dam™ system can also be used to protect refineries from threatening flood water.
  • Containment for Sewage
    Many cities in older areas have combined sewer systems (sewage and storm water). During peak rain events, the system cannot handle the capacity and spills directly into the river system, bypassing the sewage treatment. Containment, specifically placed could control large volumes of water accumulation to reduce the threat of the combined system reaching its capacity causing raw sewage from going into the river system.
  • Golf Courses
    The Tiger Dam™ system can be used to protect golf course fairways and greens from costly damages caused by flooding by diverting rivers and other threatening water sources.See Tiger Dams South California » https://bit.ly/3cx3ZPo
  • Personal Property
    The Tiger Dam™ system can quickly protect your property from the onset of floods. By strategically placing the flexible barrier around your home you can prevent floodwaters from destroying your property and assets.
  • Road Ways
    Tiger Dam™ can be used to keep roadways open during flood events, and can be used when constructing roadways, crews can effortlessly implement the Tiger DamTM system to prevent runoff issues. This enables a hassle free environment to easily and efficiently complete a project.See Tiger Dams Detroit Flooding » https://bit.ly/2G7M85A
  • River Crossings
    Whether the need is to contain parts of a river for environmental reasons or simply to repair walkways or bridges, the Tiger Dam™ system is an economical and environmentally friendly product that assists in making any project easier.
  • Bridge Repair
    The Tiger Dam™ system can assist in creating safe work areas for crews working on jobs such as major bridge repairs. It can be used to create coffer dams and as temporary river diversion to keep the work area accessible.
  • Water Storage
    Some floods cause irreparable damages, possibly even to a town’s water supply. When the Tiger Dam™ system is filled with clean water it can be used for safe drinking water in case of emergencies.
  • Irrigation Ditches
    The Tiger Dam™ system can be used to transport or divert water from rivers similar to irrigation channels. The product can be used to contain or channel water to agricultural areas versus excavating costly irrigation ditches, used only in low precipitation years.
