It's very good, but I still need information about the creek channel. Would you let me know who performed L-pile analyses on the piers for supporting retaining walls? He should have such information. Thanks!

I will send you a cross section of the creek wall and proposed grading for the entire park area that will include all the grades that you are requesting. Is there anything else you need at this time? Do you want PDF’s, AutoCad files or Microstation files? ________________________________ From: Eric T.
