Thanks Walter, I appreciate you looking into it. I have left you a voice mail requesting a brief phone conversation to help me finalize the scope of work for this study.

The main thing that we were trying to do is determine what was happening at the north end of the site and along Lindbergh to the west. I think that Shannon would have come to the same conclusions had he extended his study thru Lindbergh and to the north a sufficient distance. Hope that this helps, Walter E.

I'd like for us to be on the same page as far as models go. Thanks for your help. Regards, D. Ryan Plasse, P.E., CFM Director of Water Resources 8350 N.
