How to Read a Flood Plane Map
A Flood Plane Map contains valuable information that is pertinent to industries such as oil and gas, construction, Pipeline construction, as well as industrial construction. Flood Maps may incorporate these jurisdictions: Counties, Townships, Towns, as well as Cities. FEMA allocates each a six-digit Community Identifier (CID).
There are two common types, Flat Flood Maps and Z-Fold Flood Maps. The flat flood map includes one, sometimes more, 11”x17” pages, while the Z-Fold Flood Map is larger and folds up as a road map commonly would. Every flood map has the basic essentials, including the index map, panel, title box, legend and standard symbols that remain consistent from map to map. Regardless of what kind of map is being used, most will only cover one jurisdiction at a time.
Flood Map Overview.
The Index: acts as a guide to map sheets found on a Flood Map. As the geographic coverage of a Flood Map is often quite huge, FEMA splits the range into segments named panels.
The Panel: The Community might contain more than one individual maps. Each map is a panel.
The Title Block: Available on each Panel (or page), and the community name, date, the panel/page number.
Community Name: The title block portrays name of the mapped community, the county, and the state.
Community Number: the community identification number (CID), allocated to the mapped community.
The Body: Presents the map contents. Within the body, there are places of reference to pinpoint specific locations.
Corporate Limit or County Line: identifies the jurisdictional boundaries of the community’s regulatory authority over constructing or land development.
The Legend: Z-fold Flood Maps, the Legend features data for determining the risk zones and/or floodway on the Flood Map.
North Arrow: This arrow orients the Flood Map.
Panel Limit Line: outlines the section covered by each panel presented on the index.
Flood Maps possess flood hazard data on one or more communities. Before beginning any project or development, a company may need to identify Special Flood Hazard Areas (SFHA) or undeveloped coastal barriers, wherein flood insurance is not available. Businesses, organizations or individuals concerned with flood control will also find flood maps valuable.

What Makes The Aqua-Barrier® Cofferdam Design So Effective?
Many people look for flood control and dewatering solutions that are safe, effective, and easily installed. Since 1996, Hydrological Solution’s Aqua-Barrier® Cofferdams have been manufactured in Texas and sold throughout the United States. Hydrological Solutions offers a unique patented cofferdam design making it the most effective dewatering solution on the market.
The Key to the Design: A Three Component Stabilization System
Internal Baffling System
The first component in our stabilization system is the Internal Baffling System. Without the Internal Baffling System, the cofferdam would not be able to withstand the pressure against invasive waters. Our patented internal baffle system will lock into place when the barrier is exposed to uneven water pressure. The Aqua-Barrier® system gains its stability through the tension of the inner restraint baffle(s). Once the system is inflated the baffles prevent the barrier from rolling. As the barrier is exposed to water pressure there is a natural adjustment towards the side of the least hydrostatic (water) pressure.
The next stabilization component is the use of Freeboard. Freeboard refers to the amount of inflated barrier above the surrounding water level. A minimum of at least 25% freeboard is required in all Aqua-Barrier® installations. Freeboard requirements may increase if the barrier is exposed or has the potential to being exposed to high water velocities (3-ft or more per second), slick soil conditions and other relevant hydrostatic conditions.
Lastly, the Aqua-Barriers® are engineered to utilize surface friction in order to stabilize when exposed to uneven hydrostatic pressures. If exposed to weak soils or other surfaces, the barrier may slide and require additional pipe support, a wider footprint, or freeboard.
Our cofferdams are constructed from industrial grade vinyl coated polyester. This fabric is laminated with a base of woven polyester between two layers of flexible polyvinyl chloride. This material makes handling, maintenance, storage, and repair of the barrier quick and easy. Combined with a stabilization system comprising of Internal Baffling, Free Board, and Surface Tension, the Aqua-Barrier® Cofferdam becomes one of the most uniquely engineered cofferdams available.

Several major storm systems have moved through the central part of North America, with Texas and Oklahoma being the most severely affected. Tornadoes and flooding have caused major damage, especially in Texas, where the death toll is now over 20. And it’s not over yet; another round of storms is expected to hit over the weekend in these areas. Hundreds have already been evacuated, and more may have to be evacuated as well in this next round.
This is where we at Hydrological Solutions can help. We have flooding and dewatering solutions to help keep damaging water at bay. Our Aqua-Barrier® is a water-inflated cofferdam with a patented internal baffle system that can keep water at bay around water-sensitive work areas. It is designed to be portable and is made from materials that make it easy to be reused, stored in small spaces, or repaired if necessary.
We also have a product designed specifically for flood protection for residential or commercial areas: our Water Inflated Property Protector, or WIPP® system. It is a better solution than sandbags because it is reusable, environmentally friendly, and does not require Hazmat procedures for disposal. And, like the Aqua-Barrier®, it is also water-inflated and designed for easy transportation, storage and repair.
Don’t let your property or work space be invaded with water, which can be quite destructive and cause costly damage. Protect your property with our flooding and dewatering solutions. For more information about our products and services, contact Hydrological Solutions today!

It is that time of year when the pool covers start to come off and people start to jump in for some fun in the sun.
However, sometimes when that pool cover comes off, damage is discovered that needs repair. If you have pool damage but do not want to go through the cost and hassle of draining the entire pool just to fix one little spot, we may have something that can help.
Our Aqua-Barrier cofferdam can provide a dry work space to make repairs and perform pool maintenance that will not require draining the entire pool. It is a tool designed specifically for the purpose of creating a dry space in an aquatic environment.
The Aqua-Barrier has several features that set it apart:
- It has added stability due to its patented internal baffle system that locks into place when it is exposed to uneven water pressure, allowing it to keep water out, even when the water is not still.
- It is also easy to handle and easy to store, even in a compact area, for further use because it is made from a base of woven polyester between two layers of flexible polyvinyl chloride.
- And, if it should get damaged, it is also easy to repair.
- Finally, we will provide a representative to help you to install and dismantle the Aqua-Barrier® and provide you with an instruction manual for further assistance.
