Dave and Dale agreed that it would be best to construct a 5'to 10' long rampjust behind the 1'sill of the low flow barrel to prevent a waterfall effect. Dave also mentioned thatthe ramp will help aquatic life moving upstream. With the amount of sand lining the banks ofthe existing stream, Dave feels thatthe streambed ofthe low flow barrel will naturally establish itself pretty quickly. Dale asked if cnaterial ex�avated for the �ulvert site �ould be used for the high flow barrels, if it is socnewhat sandy, Dave felt that it should have a sandy texture and agreed, On�e �onstru�tion starts and ex�avation begins, Stephanie will return to the site to view the ex�avated cnaterial and �onfircn the texture, � The field of Par�el # 4 has an 8" drain pipe ecnpting into the �reek, Water was �onstantly flowing during the cneeting, As shown on the roadway drawing, the pipe will have to be extended when the existing �hannel is filled in, � Onsite rain gauges will be used for NPDES reporting, Stephanie asked that the NPDES reports not be signed until all inforcnation for the week had been entered, If you have any questions, please let cne know, Larry B.
