Box 478 Coppell, Texas 75019-4409 Re: Slope repair behind homes on Parker Drive Dear Ken: As I mentioned to you this week, as described on the two phone messages I left with you, I am very concerned about the potential slope failure upstream of the repair we are now installing behind our properties. When I first reviewed with you three months ago the proposed repair that is now underway, I conveyed to you my concern as to the repair being vulnerable to eddy erosion upstream from our northern most property line. Now that our repair is well underway, I can now clearly see the weak point in our collective fix. I requested or'you at that time to take this potential failure into consideration during the approval process of Windsor Estates. Our soil engineer, John Bryant (972-713-9109, Cell 214-207-5980) performed extensive hydrologic work along the entire cut bank, including Windsor Estate, which flagged this concern early on. I would suggest that you give John a call as he may have some suggestions regarding the mitigation of the risk while Kelly Jordan is involved in the development of the site. I hope to work with you in addressing this issue. the alternatives later on. Please give me a call at your convenience. 977 Parker Drive 972-304-3260 E-mail: Steve~psycor.com It is best to deal with this pow as opposed to
