Page 3. Mined La• Reclamation Board. • i 6. We request that water-and-energy-conserving procedures be used during revegetation. We note that the sprinkler system used on the Turnpike Pit property has resulted in overwatering of adjacent residential lawns and gardens. �. We request the immediate planting of topsoil stockpiles which will be left in existence beyond one planting season to control their erosion by wind or water. 8. We ask that environmentally-safe planting and growing procedures be used which will preclude growth of Russian thistle or other noxious weeds . Our experience with the Turnpike Pit revegetation program provides proof that unless proper planting techniques are used carefully, grasses and weeds from adjacent property will invade neighboring lawns and gardens , to the detriment of those residential property owners. 9. Equine encephalitis is a disease which has occurred in Boulder County and is transmitted by mosquitoes to human beings , with undesirable consequences for the victims. The proposed reclamation plan includes several lakes covering a total of approximately 41.5 acres . Their nearness to heavily-populated residential areas could pose a health hazard should these lakes and associated marshy areas provide breeding areas for mosquitoes . Therefore , we request that the slope of the lakes for 10 feet below the water line be no less than 4:1 , and that the mosquito- larva-eating fish Gambusia a£finis be stocked annually in these lakes . The fish must be stocked annually because it does not reproduce well in such lakes . We ask that other environmentally- safe control measures be required if necessary. 10. The Flatiron Sand and Gravel Company has received Boulder County ' s permission to operate on the Deepe Farm site for a period of ? years (beginning Jan. 11 , 1982) or through the completion of the first two stages of mining, whichever comes first. Whether or not subsequent mining occurs will be determined by how the initial 7 years of mining affect nearby neighborhoods . Therefore , we request that the permit issued by the Mined Land Reclamation Board be so worded that should subsequent mining not be approved, prompt completion of reclamation will be required so that the land will be ready to become Open Space within 2 years of the expiration of the current Boulder County Special Use permit. We have been working with the relevant City and County Departments , the County Planning Commission, and the company for five months to define conditions which will permit us to retain the desirable characteristics of our residential areas and at the same time , make mining of the Deepe Farm site feasible for Flatiron Sand
