Site work for a water / sewer project in Frankfort, Kentucky. Completed plans call for site work for a water / sewer project.

The proposed Clara Lutz Drainage, approximately 1/2 acre, consists of an acidic seep, high in iron in Hopkins County.at Barnsley. The site is located at 37 15' 23" N, 87 29' 20" W. To reach the site from Madisonville, follow US 41 South for 5.9 miles. The site is at the intersection with US 41 and Barnsley Loop. Laboratory samples show the seep at its source is extremely high in Iron and elevated Manganese. The aluminum levels were not elevated. The site is being designed to control and treat the iron discharge. The site will be accessed from US 41. There is an existing culvert in the ditch line. Proposed at the source of the seep is an Anoxic Limestone drain. The limestone drain is 60' x 30' x 5' and covered with a minimum of 1' of soil. The drain will be lined with 20 mil pvc liner and wrapped burrito style. The rock in the drain will be high purity limestone sized 2" to 6". The anoxic limestone drain is proposed to discharge into an aerobic filter wetland. The wetland will be lined with 20 mil pvc liner anchored into the soil. A 6" layer of no. 2 stone will be placed then a 12" layer of hardwood bark will be placed. Wetland species such as cattails will be planted in the wetland. The water depth in the wetland will be 6" to 12". The wetland discharges into the roadside ditch. The seep drainage will need to be temporarily routed around the construction area via a diversion ditch. Limestone sand is specified to treat the water in the ditch while construction is ongoing. Construction disturbances will be kept to a minimum with a stringently formulated sediment and erosion control program. Prior to beginning any disturbance (excluding initial site preparation for access only), all silt control measures will be installed. Silt control measures include straw bales and/or silt fence. Most of the site is clear and has been maintained. However, there are two or three trees greater than 3" diameter at breast height that will be cut. All disturbed areas will be promptly revegetated at the end of construction. Project Estimate: $103,315
