<br />Canon City Flood Hazard Mitigation Plan <br /> <br />8/25/98 <br /> <br /> <br />Figure 15 - Sandbagging Steps <br /> <br />For most flooding situations, a homeowner <br />should consult with a professional engineer to <br />be certain that the closure system being <br />planned can withstand the hydrostatic and <br />hydrodynamic pressures that will be involved. <br /> <br />Low Profile Permanent Closures <br /> <br />For cases involving flood levels of up to two <br />feet, a type of "mini-flood wall can be used to <br />permanently protect various types of open- <br />ings. Possible materials for this use include <br />brick, concrete block and poured concrete.

Though the "mini"-walls <br />may not require the d,!lgree of reinforcing of <br />larger flood walls, they should be supported <br />by and securely tied onto a footing so that they <br />will not be undercut by scouring. <br /> <br />Sandbagging <br /> <br />As a last resort or during emergencies, sand- <br />bags can keep water away from vulnerable <br />property. However, flood proofing measures <br />and moving contents out of the way are much <br />more secure methods to accomplish the same <br /> <br />Flooctside <br /> <br />House side <br /> <br /> <br />Figure 17 - Sandbag Wall Cross-Section <br /> <br />15 <br />
