Mowing. <br /> <br />One annual mowing at $30 per acre for <br />80 acres. <br /> <br />3. Routine Erosion Damage <br /> <br />Estimated erosion loss equals ] ton per <br />acre per year (0.75 c.y./acre per year). <br /> <br />Total annual loss : 80(0.75) : 60 cy. <br /> <br />Unit cost estimated at $40.00 per cubic <br />yard ($17.50 for hand excavation, $0.50 <br />transportation, $]1.00 placement and <br />compaction, and $1.00 for reseeding). <br />This amount is multiplied by ].33 to <br />allow for wet years. <br /> <br />Erosion repair cost = 60 cy at $40.O0/cu.yd. <br /> <br />4. Vegetation and Soil Amendments <br /> <br />Assure 10 percent area amendments per <br />year for the five year period. The <br />cost for repair of vegetation will be <br />$100 per acre. <br /> <br />83 acres (0.10) $1,000 : <br /> <br />5. Fence Replacement <br /> <br />Replace five (5) percent of the total <br />length of fence at the site every year. <br />Estimated total required length of <br />fence at the site is about $7,500 feet. <br /> <br />7,500 feet (0.05) x $5/foot <br /> <br />6. Groundwater Monitoring Well Replacement <br /> <br />Assume that two monitoring wells would <br />be damaged to the degree that they <br />would require replacement within the <br />five year period. <br /> <br />[2/5] $1,000 per well <br /> <br />7. Groundwater Nonitoring Program <br /> <br />Sampling will be required 4 times per year <br />for the Table ! parameters.
