Evaluation of Potential Impacts to Groundwater Basin • Evaluated potential impacts at a range of basin storage conditions (from 200,000 acre-feet to 500,000 acre-feet accumulated overdraft) • Utilized basin computer model to conduct 14 different model runs, evaluating a number of different conditions (for example, different BPPs, different amounts of assumed annexation pumping) • Modeling results used for Draft EIR 9
Example Uses of Model Results in EIR • Evaluated potential groundwater impacts with respect to changes in groundwater elevations • Evaluated if changes in groundwater elevations could impact groundwater quality • In summary, model results indicate requested annexations will not have a significant impact on the groundwater basin 10
