Mr. Spencer, my name is Tom Forrest and I work for the Town of Addison. I serve as a project coordinator on various Town projects, including the construction of Vitruvian Park. I recently learned that you had a telephone conversation this past Friday afternoon with the Town Engineer, Clay Barnett, during which you requested some information concerning the Town’s involvement in storm water management for the Vitruvian Park project. Specifically, my understanding is that you asked for information about silt fencing that was in addition to the silt fencing shown in the approved Storm Water Pollution Prevention Plan. In response to your request, I am forwarding an email from Clay to me, which provides the explanation about silt fencing and which includes as attachments copies of the documentation you requested. Please be assured that compliance of the Vitruvian Park project with all U.S. Environmental Protection Agency (EPA) and U.S. Army Corps of Engineers (USACE) requirements is being given our utmost attention. We desire to fully cooperate with the EPA and USACE and to ensure that the project construction activities remain in compliance with the USACE permit dated August 5, 2009. We are available at any time to meet and discuss the project with you; we would welcome the opportunity to do so and any direction you may have regarding it. As the project coordinator, I would appreciate it if you would please direct any further requests for information, and any questions you may have, to me in writing (email is sufficient). My contact information is below. We will make every effort to promptly provide you with all information requested and to answer all questions. Thank you for your consideration. If you have any issues or concerns, please let me know. Thomas L.

Those emails are attached. When I spoke with Mr. Spencer on Friday, I mentioned that the silt fence I had requested was not shown on the SWPPP and was requested in a limited area. I stated that it was shown on the SWPPP in the correspondence, however, I stated this in error. It was shown in the bid documents for the project. Therefore, I was requesting a measure beyond that shown in the SWPPP, which generated some discussion also included in the emails. The problem was that at that time the creek area lake was being excavated. UDR and the contractor felt that the silt fence would have inhibited construction traffic and the erection of the lake edge walls. The precipitating question was why would we add something that would inhibit construction if it was not indicated on the SWPPP. My response to this question was that it would offer some sediment control while allowing construction of the creek area park and that it could be added along the top of bank in order to avoid becoming dislodged and sent downstream during a rain event. Additionally, I recommended adding some openings in the fence with some rock at ground level in the openings in order to give the contractor an area to enter and exit the construction site. The silt fence was erected shortly after I had explained this to all parties. Additionally, I have attached an email dated May 18 concerning some silt fence that had been removed during construction. As the email indicates, repair of the silt fence was already scheduled when I had sent my request to have it repaired. Thanks, Clay Barnett, P.E.
