Standing water from melting snow or heavy rains can flood basements and damage yards, wells, feed supplies, machinery and other property. Flooding is more apt to occur in areas with poor surface drainage, malfunctioning drainage systems or ice dams.
A 1- to 3-foot-high sandbag or earth dike offers protection from shallow flooding (water depth less than 3 feet). Contact a construction firm, lumberyard or your county emergency government office for information on where to obtain sandbags.SITE SELECTION
Select the site for the dike, making the best use of natural land features to keep it as short and low as possible. Avoid trees or other obstructions which would weaken the structure. Do not build the dike against a basement wall. Leave about 8 feet of space to maneuver between the dike and buildings. Remove ice and snow, down to the bare ground if possible, from the strip of land you've selected.SANDBAG NEEDS
The number of bags required for 100 linear feet of dike is as follows:
See diagrams on the back side. If you are building the dike on a lawn you may omit the bonding trench shown in the diagram on Stacking Sandbags.
Seal the finished dike to increase its watertightness. To seal the dike:
Your local emergency government office, your county agricultural agent, the American Red Cross, the Federal Emergency Management Agency
