The primary concern is having a 4” water line buried 20’ deep and being able to get to it for repairs if ever needed in the future and how to accomplish the bores for this line; it shows to cross the creek in two locations. As I stated in an earlier e-mail, NTC and American is saying that there was not a line item in the bid for the bores and they did not show up on the bid set up plans. However, they did show up on the construction set and have a note “By Others”. Who are the others? In addition, the plans only have notation for bore sizes that would be too small for a 4” pipe. No additional controllers would be needed on the project. Monies would be saved with smaller mainline pipe sizes and not having to bore the creek (whoever is responsible for doing this). Most likely, one additional tap on the Ponte stub-out on the far side of the creek would be needed. Can we have a meeting to set down and talk about this?

They are as follows: My understanding from Bruce Dunne is that we must have a well in order to obtain the water rights permit for the impoundment. Because we are going to have to have a water well anyway, it might as well serve the irrigation too and save us the expense of using city water. I am not absolutely sure on this, but if we split the irrigation system into two or four separate systems does that double or quadruple the number of controllers that we have? I am not sure if we have space sufficient to place these. Additionally, they cost $8,000 apiece not including the conduits and wiring for the electrical and telephone services. Because the original engineering/landscape architecture contract has been expended and UDR has contracted directly to provide any additional design costs, any future changes would need to be done through another contract/account or we would need to ask UDR to cover the cost. If the concern is with the boring of the creek and electrical wires being damaged, wouldn’t a better option be to hang the controller wires in a conduit off the bottom of the bridge and leave the rest of the irrigation system as is?

Is a well still in the mix? If so, this will have an influence of the size of the mainline.

Little; Jennifer Haynes; Bruce Dunne; Seth Heidman Subject: Vitruvian Park Ron – Do you want to go ahead and schedule a meeting with Irri-tech for this Thursday or Friday? I can do Thursday afternoon after our tree field trip, or we could meet with Seth at 10 and then do the trees immediately after. Or I can do Friday AM at 10 or 11. I am not sure of the time line on this issue, but I don’t want to drag it out another 10 days as I am out tomorrow and on vacation next week. Thanks. All – Who (in addition to Ron, Irri*tech and me) needs to attend this meeting? ________________________________ From: Seth Heidman [mailto:SethH@irri-tech.com] Sent: Tuesday, November 16, 2010 3:07 PM To: Robyn Jacobson Subject: Vitruvian Park Robyn, It will be feasible for the Town of Addison to isolate the irrigation system into four independent systems per their request. According to my records, the static pressure at the site is 81 psi, which is very good. We would need to adjust some rotary zone sizes throughout the project, add new 1-1/2” water meter on northeast side, and possibly add a second 1-1/2” water meter on northwest side. Still have not consulted with Rainmaster rep on what it would take to isolate the controllers, but will keep pursuing. PS. One question I have is if Addison still wants the mainline to be oversized to allow for future well and pump station. We can discuss this with Ron Lee at the appropriate time.
