Subsidence project is in Port Clinton in Ottawa County, Ohio.  The site is located approximately 0.41 miles south of the intersection of E. State Rd. and S. Plasterbed Rd. The scope and intent of this project is to drill and grout an area of abandoned underground gypsum mine(s) to remediate a subsidence feature that has impacted a small area of S. Plasterbed Rd. Proposed reclamation shall include approximately: * 950 cubic yards of concrete, * 300 cubic yards of grout, * 650 linear feet of drill holes (vertical/angled), * 500 linear feet of casing, * 4 square yards of asphalt, * 200 linear feet of existing fence dismantling and resetting, * Site surveying. Temporary erosion and sedimentation controls including silt fence and straw bale dikes shall be implemented.  Following drilling and grouting operations, the applicable site areas will be limed, fertilized, seeded and mulched for permanent stabilization. The project officer for this project is Rachel Lumpcik in the New Philadelphia Office (614) 623-0206, and the project engineer is Scott McDiffitt, P.E. in the New Philadelphia Office (740) 248-8609.

MANDATORY PRE-BID MEETING ON JUNE 25, 2024 at 10:00 AM. The Pre-bid meeting location coordinates are 38.951136 N, -82.562780 at the intersection of S.R. 93 and Roscoe Road. Project Name: Cooper Hollow Waterloo Dam Removal Project Description: The Cooper Hollow Waterloo Dam Removal Project is located in the Division of Wildlife's (DOW) Cooper Hollow Wildlife Area, approximately 3.15 miles south of Winchester, Ohio, in the Madison Township of Jackson County, Ohio. From Oak Hill Middle/High School, turn left onto OH-93 North for 1.9 miles. At the intersection of Ohio State Route 93 and Pyro Road, turn right onto Pyro Road and continue straight for 0.1 miles. Next, turn left onto Zoar Church Road and continue for 1 mile before turning right onto Mining Haul Road. Continue on Mining Haul Road for 0.1 miles and turn right to stay on Mining Haul Road. Continue for 0.6 miles before reaching a left turn onto the access road leading up to the Cooper Hollow Waterloo Dam. The coordinates of the project area are 38°56'24.24"N, 82°32'31.38"W. The Pre-bid meeting location coordinates are 38.951136 N, -82.562780 at the intersection of S.R. 93 and Roscoe Road. This project shall reduce the overall capacity of the Cooper Hollow Waterloo Dam, formerly known as the Waterloo Coal Company Dam (IM-0978). The dam was originally constructed to aid in mining activities. An ODNR Division of Geologic Survey Records indicated that the closest mine was approximately 1000 ft. North of the dam. These are the Waterloo Coal Co. C- 0854 and C-0370 mines, permitted in 1981 and 1942, respectively. The primary coal seam mined was the Lower Kittanning No. 5 seam. Additionally, the 1961 Oak Hill Quadrangle USGS map indicated that extensive strip mining also took place in the 1940s or 1950s as well. The project proposed to reduce the dam height to less than 10 ft. and decrease the storage capacity to less than 50 ac-ft. exempting it from Dam Safety Jurisdiction. Additional work will include removing the principal spillway pipe, addressing the erosion issues on the dam crest / embankments, and clearing the area of trash/debris. A design requirement is to maintain drivable access across the dam post-construction. All spoil will be placed at the DOW’s existing borrow area. This project will require excavation and disposal, compacted embankment, riprap fill, the removal of the existing principal spillway pipe, and installation of two proposed principal spillway pipes to reduce the capacity of the dam from its currently listed height of 18.8 ft. and storage of 51 ac-ft. to less than 10 ft. and less than 50 ac-ft. This will also require construction of a new emergency spillway with appropriate riprap protection and to correct damaged drainage patterns due to erosion and sedimentation. The project also proposes improvements to the existing access road and installation of a construction entrance that will provide access to the dam. These improvements will require the use of aggregate base, subgrade compaction, and the use of a longitudinal channelizing device to create ditches on each side of the access road. A kayak/canoe launch point will also be installed as part of the project. The project will also make appropriate use of silt fence, straw wattles, and reseeding practices as erosion and sediment control practices.
