<br />derived from coal end vater interactions. In addition, there are several <br />clay and gravel mines in the project area that'vould be eyesores if they <br />vere left untouched. There are also one or more exposed shafts or holes <br />that vould be a safety hazard in a public use area. Also, a cessation <br />, of mining vi thin project boundaries could cause an increase in mining <br />activity on adjacent lands. The impact of this is the possible creation <br />of neli eyesores vhich, vithout the project, probably vould not have <br />occurred until a much later time, or not at all. <br /> <br />2. Recreation - An adverse effect associated vith recreation <br />is the heavy impact of human traffic on semi-arid vegetation. Excess <br />traffic on these plant types will compact and Year dovn the vegetation <br />in much the s wne yay that overgrazing does. <br /> <br />D. Remedial, protective and mitip;ative P.'.!'~es. <br /> <br />1. Relocations - More than 3,000 acres of land, including 228 <br />surface acres of vater, vould be devoted to public use. This viII offset <br />the fact that several farmsteads, residences, a mobile home trailer court, <br />and some businesses "ill have t" be relocated. Earth formation plus <br />strategic tree and shrub plantings vould be considered for a noise <br />barrier between the proposed 1-470 right-of-way and public use areas <br />of the project. <br /> <br />2. Loss of Vegetation - In order to partially mitigate the loss <br />of trees along streambanks the existing trees, whenever possible, would be <br />moved back to the lake edge with large tree moving equipment. Trees <br />and shrubs lost to construction would be replaced by new plantings. <br /> <br />The present highway ',system has been designed to accommodate <br />projected increases in traffic associated "ith the proposed project and <br />its effects on the surrounding areas. <br /> <br />3. Mineral Reserves - Present mining vould continue until land' <br />acquisition takes place and then would cease. Upon conversion to Federal <br />ownership, any mining which is considered to be in the best interest of <br />the country, and which would not create any significant adverse impacts <br />on the project ,could be continued. It would be conducted in such a yay as <br />to minimize site alterations and to provide adequate erosion control <br />and revegetation. <br /> <br />Acid mine water drainage problems are not anticipated from coal <br />mines outside of the project boundary because these mines are small, <br />distances from the project are great, they apparently are not causing <br />problems now, and they are not expected to be affected by any changes in <br />ground vater levels near the lake. <br /> <br />8 <br />
