John, Attached is an exhibit from Andres showing what they would like to do in the right of way. My concern is that if someone went trenching into the right-of-way, be it the Town to repair a line or another utility provider, they could cut these soil nails and compromise the integrity of the retaining wall. This could result in the failure of the wall and the roadway. The roadway, although expensive could be repaired. A larger concern is if anyone is working in the area beneath the retaining wall. Although the odds of this occurring all at the same time is extremely slim, the risk does exist. What would our liability be in that case? Is it something that can be addressed in an indemnity statement in the license agreement? The retaining wall is temporary until the foundation is complete. I will get an estimate of how long it will take to complete the foundation and backfill the wall. Thanks, Clay Barnett, P.E. Town Engineer Town of Addison 16801 Westgrove Drive Addison, TX 75001-2818 Office: (972) 450-2857 From: Jared Powell [mailto:Jared@andresconstruction.com] Sent: Thursday, August 25, 2011 2:01 PM To: Clay Barnett Cc: Jeff Kempf; Tanner Whitson Subject: VP 206--Soil Retention System Clay— I have attached the drawings we briefly discussed this morning. The drawing shows the basic concept of the soil retention system we plan to install along Vitruvian Way and Bella Lane to protect the new roads and utilities while we excavate and build foundations for Vitruvian Block 206. We are in the process of releasing Craig Olden, Inc. to begin engineered shop drawings that will include exact dimensions, but we wanted to make T.o.A. aware that the soil retention nails will extend past the property line and into the public right of way. These nails will be below the existing utilities in this area, and we will perform exploratory work to determine actual depths prior to placement of the nails. This is a system that is commonly used in urban setting and the nails are temporary Please let me know if you see any issues with this, or if there are any additional permits, ROW rental fees, etc. that may be required.
