This best describes the bustling region of South Florida, which theoretically encompasses 24 counties and more than two-thirds of the state's population. Its growth, however, is constantly stunted by its geography. As a result, hurricanes and storms can easily take pot shots at major cities like Miami that are just five feet above sea level.
Coupled with overdevelopment, the region’s geographical disadvantage makes it constantly vulnerable to floods. Rising sea levels as a result of climate change aren't making its precarious situation any better.
Local governments have resorted to creativity in creating solutions. For Ken Todd, chair of the Palm Beach County Water Resources Task Force's technical group, storage is key.
"For water management in South Florida now, the mantra is, 'Storage, storage, storage.' You're going to get the rain, and you don't want that in someone's house, so where do you put that water? You've got to create storage, and it has to be in a place that nobody cares about."
Take note that detention basins aren't the same as retention basins. Both are widely used for flood control, but the former only holds water for a short period.
Although detention basins use the lay of the land to contain runoff, some have concrete linings. This is normally the case when the runoff contains contaminants that must not sink into the soil. One example exists in the Port of Seattle with a capacity of 1.6 million gallons to be retreated for reuse or discharge into natural bodies of water.
Aluminum concrete forming systems can make these basins possible. The wall forms can be set around the planned basin before pouring cast-in-place concrete. Not only does the plan create robust foundations and walls, but it also promotes green construction practices. For starters, these wall forms can be used up to 2,000 pours, greatly cutting costs for massive purposes like the above.
Cast-in-place concrete itself is also green thanks to waste minimization. Today's concrete mixes are largely composed of recycled content, yet still produce hardy concrete. As the term implies, the concrete is poured into the concrete forms, which are preset as walls. Cast-in-place concrete can be transported more easily (via cement truck) than formed panels. Contractors can find these aluminum concrete wall forms for sale at Southeast manufacturers like Leco Concrete Forms & Supply.
