I've asked the same of 2 other local civil engineers and they are also shrugged their shoulders. Is it possible I am misunderstanding your request on this item? Won't the City curb, gutter and install storm drainage system and carry the water to the creek at that time? Looking forward to getting this started, we have a decent chance of rain next week and I have contractors on standby!

Provide additional flowline shots : ditch west towards and including main culverts at Greens Prairie and Royder, ditch eastward . 2. Design and construction should include ditch improvements all the way to noted western main culverts. 3. Backwater impact from the creek. 4. A profile of the ditch improvements would be beneficial. 5. Confirm there is not additional eastern area draining into subject ditch improvements. 6. Velocity for sheet flow of 0 .25 ft/s appears low, increasing to 1 or 1.5 ft/s would likewise increase the flow. 7. Berms of 302.8 and 304.1 do not appear to be depicted with the proposed contours. 8. Provide proposed min finished floors for lots adjacent to the ditch in future phase. 9. This submittal did not provide analysis of the private drainage system installed in the rear of the lots. 10. This should be an NO! not Site Notice to TCEQ . 11. There should be a freeboard from the 100 yr water surface elevation to the berm and adjacent f i nish floors to account for a margin of error, clogging factor debris in culverts, etc. 12.A consideration for how the future expansion of Greens Prairie Trail would accommodate this proposed drainage design. 13. Confirm compaction and vegetation specs .

The most significant of which is we think the regrading work should be extended all the way to the creek. We'd like to sit down and discuss the comments with you if you have some time tomorrow morning. Would 10 or l l work for you? 2 Thanks, Erika From: Rabon Metcalf [ mailto:rabon@rmengineer.com] Sent: Tuesday, June 03 , 2014 5:02 PM To: chris@oldhamgoodwin.com; 'Travis Nance' Cc: Erika Bridges; Alan Gibbs Subject: RE: Complete Memo Greens Prairie Trail Bar Ditch (DP)# 14-141 Ericka: Attached is the fully executed DP.
