Clay, Attached is an exhibit that will help explain a couple comments about construction staging, detention, and releasing existing drainage easements: 1. As we discussed, I’m trying to figure out how to get the City to formally “accept” drainage improvements that allow for the Fedex and State Farm surface drainage easements to be released prior to digging the pond (or, worst case scenario, prior to digging part of the pond). Highlighted in blue is the series of storm sewer that David Meyers believes will handle the off-site drainage from Fedex and State Farm. Once we put this storm sewer in, will the city issue an “acceptance letter” that I can present to State Farm and Fedex to get them comfortable that their surface drainage easements are no longer necessary? We don’t believe we need either State Farm or Fedex to formally sign-off on the release of the easements, but we’d like to have a letter from the City acknowledging that the work has been accepted just in case someone asks. 2. We talked about construction staging and I got a little too aggressive in my comments about putting our construction trailer and storage yard in the detention pond. My guys noted that while we may not flood the trailer it will be a major mess to try to navigate through slop when we get a little rain and anything stored in the area has the potential to be damaged by sitting water. It will also be very hard to navigate trucks and bobcats through the mess to get to materials. So, we’d kindly ask you to consider 2 options: a. Option 1 would be to allow us to build the pond at the end of the construction process to give us maximum area to park, store materials, and locate a construction trailer. If you can’t get comfortable with that option, then: b. Option 2 would be to allow us to dig +/- 50% of the pond up front and leave the balance of the pond (outlined in red) at current grade to give us some level area for trailer and material storage. We would then come back and complete the balance of the pond towards the end of construction. The area shown follows the 640 contour line. When you’ve had a chance to review, would you call me to discuss your thoughts? I’d appreciate it. 210-386-0062.

You were going to forward to Clay with further explanation. I am working on Dennis’ idea on the dog park.
