<br />4th Street Floodwall Project <br /> <br />City of Fargo <br /> <br />BACKGROUND <br /> <br />During spring flooding in 1969, the City of Fargo constructed an emergency earth dike <br />along 4th Street between 9th Avenue & 14th Avenue South. The "temporary" dike was <br />left in place after the flood event serving to protect the area from flood events occurring <br />in 1975,1978,1979,1989 and 1993. City attempts to upgrade this dike to a permanent <br />certified dike were stymied for many years by building encroachments, right-Qf-way <br />limitations, riverbank stability concerns and funding availability. Following the 1993 <br />flood disaster declaration, FEMA approved a conceptual plan to upgrade this dike. <br /> <br />PROJECT <br /> <br />The dike upgrade project included a river hydraulic analysis to determine flood plain <br />in1pacts, reconstruction of existing "temporary" dike, relocation of one house, dike <br />raising to levels appropriate for certification through use of concrete and segmented <br />block retaining walls, and storm sewer lift station enhancements for storm sewer <br />penetrations through the dike! floodwall. <br /> <br />BENEFITS <br /> <br />The existing temporary dike was unstable and not high enough to provide flood <br />protection to the area. Upgrading the dike has provided permanent and secure flood <br />protection for the City's new $70 million watertreatrnent and distribution facilities and <br />public sewer facilities along with approximately $75 million of private facilities in the <br />area. The permanent facility will prevent the need for extensive emergency flood <br />protective measures required during the spring flood of 1997. It is estimated that the <br />Improvements will prevent future flood damages of approxlmately $3.8 million for <br />flood events slmilar to 1997. <br /> <br />PROJECT COST <br />$804,000 <br /> <br />FUNDING SOURCES <br />FEMA- HMGP <br />North Dakota <br />CDBG <br />
