said the operation maintenance cost and capital costs were rolled into a production cost, which <br />would be paid for over 20 -years, with seven percent (7%) interest. <br />D. IMPLEMENTATION SCHEDULES <br />Dr. Gleason used a PowerPoint schedule to explain each option, the estimated <br />years for implementation, and the actions that would be required. <br />E. INTERIM NEEDS (LE. CONTINUED UPPER FLORIDANAQUIFER) <br />Dr. Gleason informed the Board that upon completion of the current expansion, it <br />would meet demands through 2011. He noted that if the County would implement an alternative <br />source, such as surface water, it could take approximately ten years to complete it. Since an <br />interim source would be needed between now and the next ten years, he proposed installing the <br />final three Upper Floridan Aquifer wells at the North County to bridge the gap, and once a new <br />source is constructed and on line, the Upper Floridan Aquifer withdrawals could be reduced, <br />with the difference being supplied by the alternative source. <br />F. RECOMMENDATIONS <br />Dr. Gleason recommended the long term source to be surface water, and <br />emphasized the County should work closely with SJRWMD. He suggested using aquifer storage <br />and recovery to minimize drought impacts, and to use additional Upper Floridan Aquifer wells to <br />bridge the gap for implementation. He recounted the development of a new surface water <br />treatment plant and said it would be desirable to submit a permit application to SJRWMD as <br />soon as possible to begin the ten-year process. <br />G. NEXT STEP <br />Dr. Gleason summarized his presentation by suggesting the Board approve the <br />recommended option. He wanted to receive public comments, then finalize the Alternative <br />5 <br />June 21, 2007 <br />ALTERNATIVE WATER SUPPY <br />MASTER PLAN PUBLIC WORKSHOP <br />
