<br />Floodwalls and Levees <br />Floodwalls and levees are free standing structures that prevent floodwaters from encroaching into <br />the protected buildings. They may completely surround the building or protect only the low side of <br />the property. Construction of floodwalls and levees may require local, state, and/or federal permits <br />in order to protect other properties from adverse impacts, to avoid filling in wetlands, and to <br />maintain regulatory floodways. The desired aesthetics of the neighborhood should also be taken <br />into account when considering a floodwall or levee. The most important consideration is that <br />property owners who have constructed a floodwall or levee should not have a false sense of security <br />about their property protection. The protected area should always be evacuated prior to flooding. <br /> <br /> <br />Dry Flood Proofing <br />This technique involves sealing building walls with waterproofing compounds, impermeable <br />sheeting, or other materials and using shields for covering and protecting openings form <br />floodwaters. Dry flood proofing works best on structures in the flood fringe where the flows are <br />shallow with low velocities. It is not generally recommended for buildings with a basement or a <br />crawl space due to underseepage problems that can occur. Building walls can be protected to a <br />height of about three feet, depending on building construction. <br /> <br />C. NON- STRUCTURAL MITIGATION <br />Mitigation can and should also include equally effective non-structural measures such as flood <br />insurance, emergency preparedness, public education and awareness, and acquisition and relocation <br />of structures. These measures are briefly described below. There are numerous mitigation <br />documents available, and the CWCB can provide further information and assistance to interested <br />parties, The Colorado Office of Emergency Management and the Federal Emergency Management <br />Agency have information and expertise in these areas as well. <br /> <br />Flood hlsurance <br />The National Flood hlsurance Program (NFIP) is a federally subsidized program that is available to <br />any property owner whether or not the building is in a floodplain. Insurance is sold through a <br />private insurance agent who wants to sell it in a community who has joined the program. As of <br />August 5, 1986, Jefferson County has been participating in this program. The NFIP is based on an <br />agreement between local communities and the federal government which states that if a community <br />will implement measures to reduce future flood risks to new construction or substantial re- <br />construction, the federal government will make flood insurance available within the community as <br /> <br />10 <br />
