<br />Yellowstone Mitigation Project <br /> <br />BACKGROUND <br /> <br />Park County experienced a record flood on the Yellowstone River in June of 1996. The <br />River stayed at a very high flow for over a week causing massive bank erosion and a <br />number of houses being flooded. In June 1997, the Yellowstone River decided to pro- <br />duce yet another record flood. More bank erosion occurred, and the same houses were <br />flooded again. Both floods were equal to the lOa-year, 1% frequency flood. Mitigation <br />was obviously needed for the residential structures, yet relocation was out of the <br />question due to the price of land/lots in this area, which is known as Paradise Valley. <br />Many property owners did not have the resources necessary to mitigate the flooding <br />problem But thanks to FEMA and the Flood Mitigation Assistance Program (FMAP), <br />funding was available to assist in mitigating hazards. One property owner, Mr, Jerry <br />Centers, took advantage of this program He worked with the Couni}J who acted as <br />the applicant and applied for a grant to elevate his house. Park County applied for a <br />FMAP grant to the DNRC Floodplain Management Program The Grant was awarded <br />in the middle of February, 1998. <br /> <br />PROJECT <br /> <br />The project consisted of simply elevating the house to the standards identified in the <br />Park County Floodplain Management Ordinance, The structure was elevated so the <br />lowest floor was at least two feet above the BFE. The Centers contracted with a house <br />mover to elevate the structure and place a new foundation under the structure, Once <br />the foundation was completed, the house was set back down and the fill material was <br />placed around the structure for foundation protection, The project was completed in <br />less than a month, except for final landscaping. <br /> <br />BENEFITS <br /> <br />The benefits are simple, The structure, now elevated two feet above the lOa-year flood <br />elevation, will not experience flood damage to the structure, even during a 500-year <br />event. Thus, there should be no future flood insurance claims, The Benefit Cost Ratio <br />should prove to be greater than 1:1. <br /> <br />PROJECT COST <br />$18,304 <br /> <br />FUNDING SOURCE <br />Flood Hazard Mitigation Program (FMAP) Grant funds of $13,728; Property <br />owner match of $4,576, <br />
