RE Issues for the conference callMade progress with your siphon idea. People are in working today. Both
the City of Irving (Gary Fennell) and DCURD are verbally OK with the
concept. They would like to see a written plan explaining how it would
be put into place. Gary is the contact at the City. His only real
concern is confirming a plan to shut it off when it’s raining. He’d like
to see the size of your pipe relative to the capacity of the storm
sewer. He only needs to see a written plan. 972-721-3721
I talked to Jacky Knox at DCURD. He’s ok in principle, but pointed me
to Dallas Burk. Dallas would be your contact at DCURD. They oversee the
canals that the storm drain will drain into before it goes into the
river. Dallas said his primary concern is silt and erosion so he’d like
to see the line go all the way to the drain. He’s not worried about
capacity but wants to see the info on discharge rate for confirmation.
He’d like to meet you out there to discuss it. 972-978-8671.
I told both of them that we were likely looking at 15 to 20 cfs (10-13
MGD) and that didn’t concern either one.
I’m glad to see one idea getting some traction.
Thanks,
John

Subject: Issues for the conference call
Here are a couple things I would like to discuss.
1. Dewatering thru Billingsley property
a. Permits required?
b. Route for drainage channel that Billingsley wants. Billingsley
thinks Coppell is to provide a drawing
c. Wetland issues
2. Dewater thru 42” pipe
a. Can tie-in be made on Luminant property?
b. 42” pipe drawings, who can locate these?
c. Contact for Luminant, Kyle Ray
d. What is required for TCEQ approval to excavate thru main dam?
3. Dewater thru 30” storm drain
a. Who has contact with Irving to get permission?
b. What is max flow through a 30” RCP? 12” siphon around 8 mgd
and 18” siphon around 20 mgd
c. Need to get pipe drawings from Irving. Does the 30” go
directly to Grapevine creek or does it feed some of the ponds in the
neighborhood?
4. Complete intake and conduit without lowering the lake
a. Is this a feasible option?
b. Water seepage issues during construction
c. Still need to release onto Billingsley land once intake is
complete
5. Any other options for removing the water?
