Tim, Did the flood study from Halff provide you with the information you needed or are there additional plans that you need? Thanks, Clay Barnett, P.E.

However, we usually just use Carrollton’s. I will have Dave Wilde see what he can dig up in the way of plans. If you need anything else, just let me know.

Again, if it helps I can send one of our EIT’s down there to dig thru archives. Nancy, How about the Drainage Manual? Thanks. P.

Has the manual been updated since then? Or is the 1990 version still current? Clay, We talked about as-built’s and drainage maps some time back. Specifically, we’re looking for info on the basin that drains into the Million Air ditch. Based on what we’ve gathered to date, anything north & east of Westgrove (as far north as Trinity Mills and as far east as Addison Road) would be helpful. If it helps, I can send one of our EIT’s down to search thru archives. Let me know. Thanks. P.
