96 A <br />k~FiEREAS, .other short-term alternatives fall short of the projected <br />water needs of the entire County (Capacity Use, p~31); and <br />WHEREAS, the Orange County Planning Board has stated as a general <br />policy that, "prime reservoir sites should be designated, based on an <br />evaluation of water resources throughout the County..." (O.C. Water and <br />Sewer Policy, 12/10/87); and <br />WHEREAS, the Orange County Water Supply Study has observed that only <br />two sites have the potential for meeting the future raw water needs of the <br />County: Corporation Lake. Expansion, and Eno River above McGowan Creek <br />(Water Supply Study, S-3); and <br />WHEREAS, the cost of expansion of reservoir holding capacity at <br />Corporation Lake is estimated to be $24,600,000, resulting in a cost per <br />gallon of $2.89 (compared to a total cost of $14,600,000 for the Revised <br />Seven Mile Creek Reservoir plan, at a cost per gallan yield of $2.12); and <br />WHEREAS, the building of an enlarged facility at Corporation Lake <br />would require the purchase of 1150 acres of land and the removal of <br />several structures recognized as having historical signif icance (Water <br />Supply Study, p.5-12); and <br />WHEREAS, the effective capacity of a reservoir at Corporation Lake is <br />expected to decrease over the safe yield period due to build up of <br />siltation caused by relative lack of forestation along its perimeter; and <br />WHEREAS, the construction of a new reservoir above McGowan Creek is <br />estimated to cost $24,600,000, which does not include costs of purchasing <br />existing Corporation Lake facilities, nor daes it take into account-the <br />likelihood of costly and time-consuming litigation to achieve the removal <br />of several historically significant structures (Water Supply Study, <br />p.5-25); and <br />WHEREAS, the maximum capacity of the expansion of a reservoir above <br />McGowan Creek is 4500 MG, with a 20 year safe yield of 12 MGD, at a cost <br />per gallon of $2.43 (compared with a maximum storage of 4900 MG and a 20 <br />year safe yield of 8 MGD, at a cast of $2.12 per gallan yield for the <br />Revised Seven Mile Creek Reservoir); and <br />WHEREAS, the Revised Seven Mile Creek Reservoir is designed in such <br />a manner as to provide significantly greater storage capacity (4900 MG <br />compared to 2070 MG) than the previously proposed concept; and <br />WHEREAS, the Revised Seven Mile Creek Reservoir will insure the <br />natural habitat of the area by a wildlife mitigation plan, which entails <br />the acquisition of easements to Duke Forest lands, thus preserving them <br />for ecological posterity; and <br />
