• the pond which are 2.85:1. A crack was observed in the top of the <br />embankment and the pond appears to be leaking near the toe. <br />2-B -- The elevation of the spillway crest needs to be reduced by <br />at least 0.84 feet. The spillway needs to be extended 20 feet below <br />the toe of the dam and this extension will require erosion control <br />material. All side slopes of this pond appear to meet the 3:1 <br />requirement. <br />BR-F -- Currently this pond has an 18" culvert installed for the <br />primary spillway. This needs to be removed and a spillway at least <br />8 feet wide should be installed at an elevation at least 1.32 feet <br />below the bottom of the existing culvert. This new elevation will <br />also correct the inadequate residual freeboard at peak flow that <br />currently exists. This spillway should be extended 20 below the toe <br />of the dam and this extension requires erosion control material. <br />The south side slopes need repaired as they are currently as steep <br />as 1.7:1. <br />1-C -- The elevation of the spillway crest needs to be reduced by <br />at least 1.97 feet in order to meet the 4 foot requirement. <br />However, when this modification is completed the bottom of the pond <br />and the spillway crest will be the same elevation. Therefore, the <br />pond should be removed or rebuilt as per the permit requirements. <br />U-A -- The elevation of the spillway crest needs to be reduced by <br />• at least 1.8 feet. This modification will also correct the <br />inadequate residual freeboard at peak flow that currently exists. <br />The spillway needs to be extended 20 feet below the toe of the dam <br />and this extension will require erosion control material. All side <br />slopes of this dam appear to meet the 3:1 requirement. <br />U-B -- The elevation of the spillway crest needs to be reduced by <br />at least 1.99 feet. This modification will also correct the <br />inadequate residual freeboard at peak flow that currently exists. <br />The spillway needs to be extended 20 feet below the toe of the dam <br />and this extension will require erosion control material. while the <br />majority of the side slopes meet the 3:1 requirement, material' <br />obtained from the spillway modification should be used to repair <br />the west side slope of the pond which is 2.83:1. <br />U-G -- The elevation of the spillway crest needs to be reduced by <br />at least 2.88 feet. This modification will also correct the <br />inadequate residual freeboard at peak flow that currently exists. <br />The spillway needs to be extended 20 below the toe of the dam and <br />this extension will require erosion control material. All side <br />slopes appear to meet the 3:1 requirement. <br />N-C -- The elevation of the spillway crest needs to be reduced by <br />at least 2.48 feet. This modification will also correct the <br />inadequate residual freeboard at peak flow that currently exists. <br />The spillway needs to be extended 20 below the toe of the dam and <br />• this extension will require erosion control material. All side <br />slopes appear to meet the 3:1 requirement. <br />
