Tom, As you are aware I was requested my Mr. Spencer from the EPA to send him all of the correspondence that I had concerning the additional silt fence the town requested at the Vitruvian Park project. 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. Thanks, Clay Barnett, P.E.
