1. C51 RESERVOIR PROJECT UPDATE Design, Permitting and Coordination NOVEMBER 10, 2014

2. C51 RESERVOIR LOCATION

3. C-51 Reservoir Benefits ►Existing rock mine with unique geological features ►Location is ideally suited for a multitude of water resource benefits ►Utilizes existing infrastructure for conveyance with some improvements

4.  Augmenting existing water supplies  Improving flood control in western Palm Beach County  Enhancing water quality protection for the Everglades  Reducing harmful discharges to Lake Worth Lagoon  Mitigating saltwater intrusion  Protecting against drought  Mitigating climate change impacts C-51 Reservoir Benefits

5.  The project could be eligible for a long-term permit (S. 373.236(5), F.S. and as a Preferred Water Source (S. 373.2234 F.S.)  As a multi-jurisdictional project, it is expected that the C-51 Project would rank highly for alternative water supply funding under the "Water Protection and Sustainability Program" (S. 403.890, F.S.)  Potential for permit modifications vs. a new permit C-51 Reservoir Benefits
