The Village of Cadiz, Ohio is located in Harrison County, Ohio. The village is in the midst of the shale oil activity in Ohio. Two shale oil plants have been constructed in the village, along with two new motels. In June of 2012, Ohio EPA mandated the village make improvements to their wastewater system. A tight timeline was included in the mandate from Ohio EPA.

The village’s wastewater system was constructed in 1939. No significant improvements or extensions were made to the system before issuance of the Finding and Orders by Ohio EPA. The system consisted of 197,684 linear feet of gravity lines ranging from 4-inches to 15-inches, 22,069 linear feet of 1.5-inch to 6-inch force mains, 794 manholes, 14 cleanouts, and 9 pump stations. The collection system was constructed primarily of clay pipe. The system surcharged during wet weather events. Resulting untreated wastewater flowing into nearby creeks and onto private properties.

Ohio EPA required the village to submit monthly reports and to participate in a monthly conference call with staff from Ohio EPA’s Columbus and Southeast District offices. E.L. Robinson Engineering staff drafted monthly reports for the village and participated in the conference calls. The reports and calls focused progress made on wastewater system improvement. The village was placed under a “connection ban.” No new wastewater customers were permitted to connect to the village wastewater system without approval from Ohio EPA. E.L. Robinson Engineering developed a report that tracked elimination or reduction of inflow and infiltration to the wastewater system. As I&I was eliminated by the village, Ohio EPA granted credits for new connections. It was critical for the village to maintain report and document elimination of I&I. The credits generated permitted new shale oil industries and supporting businesses locating in the village to connect to the wastewater system.

The North Trunk Collection System project is the third project completed by the village in an effort to improve their wastewater utility. This project involves replacement or rehabilitation of the many of the most problematic collection lines, manholes and other appurtenances. Work includes nearly 3,700 feet of pipe lining, 1,200 linear feet of 8-inch gravity line and 1,400 linear feet of 4-inch service laterals.

This project has a budget of $870,000. Funding for this work was provided by Ohio EPA’s Water Pollution Control Loan Fund (WPCLF). E.L. Robinson Engineering staff is currently completing planning and design of the next phase of collection system improvements. This phase is significantly larger in scope than the current project. Anticipated cost for the next phase is expected to be $8-milllion. A funding package is being developed at this time for those improvements. It is anticipated that funding will be provided by USDA-Rural Development, USACE, Appalachian Regional Commission and possibly Ohio EPA’s WPCLF program.

E.L. Robinson Engineering staff has worked with the village to complete a rate analysis to appropriately set wastewater user charges at levels that provide adequate revenues to cover operation, maintenance, capital improvements, debt service and reserve accounts.

E.L. Robinson Engineering, working as the designer for The Ruhlin Company, was successful in winning the $40,000,000 Design-Build Willow Island Power Plant Site Development Project. The project, currently under construction, involves diverting water from the locks and dam through a powerhouse to generate an average annual output of approximately 195 GWh. ELR Engineering designed and coordinated the layout and arrangement of the cellular and land-slide earthen cofferdam, perimeter slurry cut-off wall, powerhouse excavation, instrumentation, dewatering system, and temporary roads.

In addition, ELR was responsible for the preparation of all design criteria, analyses and design calculations, specifications, construction drawings, and quality control and quality assurance. The design includes construction, operation, and maintenance of the necessary facilities, including groundwater seepage cut-offs, required for dewatering the construction areas, and insuring that the completed excavation is free from running or standing water. The system incorporates pumping wells, sumps and drainage ditches to allow all work within the cofferdam to be accomplished in the dry.

The design also includes an instrumentation system to monitor the performance of the cofferdam excavation and dewatering system. During the drilling for establishing the base elevations for the dam structure within the first stage of cofferdam, a fault under existing Pier 9 and weir area was discovered resulting in changes in the footing design of the pier. The fault-shattered rock was removed, excavation was cleaned and backfilled with concrete, and the concrete gravity monolithics were replaced with circular sheetpile cells and connecting arcs. Slush grouted rock berms were placed downstream for stability and a grout curtain constructed under the weir.

E.L. Robinson Engineering teamed with the joint venture of the Beaver Excavating Company and Mosser Construction, Inc. to develop a Value Engineering Change Proposal (VECP) for the LUC-24-1272 (US 24 over Norfolk Southern Railroad) and LUC 24-1293 (US Route 24 over Ramp D) structures for the LUC-24-6.19 project in District 2. This VECP resulted in a project savings of over $3 million dollars. The VECP included the realignment of Ramp D closer to the Norfolk Southern Railroad. This allowed for the elimination of the 306 foot long precast concrete arch structure over the Norfolk Southern Railroad and the 330 foot long precast concrete arch structure over Ramp D.

The two eliminated structures were replaced with a two span rigid frame/slab structure with a 57 degree +/- skew and average length of approximately 213 feet. The structure was then classified as a buried structure and was no longer classified as a tunnel as it was now less than 300 feet in length. Tunnel lighting was replaced with standard underpass lighting and the fire suppression system and advance tunnel signing was eliminated. A strut and tieback system was provided for the two span structure to provide footing lateral stability thereby permitting the footing size and pile pattern to be reduced.

The main slab reinforcing steel was designed and detailed to be perpendicular to the substructure units. The roadway barrier was designed to be integral with a substantial reinforced concrete edge beam. The two span structure was designed for overloads as applied per the contractor’s earth moving equipment. In addition, the area of mechanically stabilized earth walls was reduced by approximately 21,000 square feet. This VECP resulted in a savings of just over $3 million dollars.

LUC-24-6.19 VECP

Project involved the replacement of the SR 109 over the Maumee River. As part of the project, alignment alternatives were developed to realign SR 109 to eliminate the existing offset intersection. The intersection with SR 109 with CR 424 was designed to change SR 109 to the predominant movement and make CR 424 a stop condition. The proposed bridge will be a 12 span prestressed concrete I-beam structure and will have aesthetic enhancements including bicycle friendly railing. The project also involved design of guardrail to provide access to a future bikepath, drainage improvements, ROW plans, traffic control, and MOT. Extensive environmental coordination was completed as the Maumee River at this location is classified as a recreational river.

This project involves the major pavement rehabilitation of I-71 from State Route 665 to Stringtown Road. The project involves full depth pavement and an additional third travel lane in each direction that will be added to the median. ELR completed a MOTAA where several concepts were evaluated, leading to the selection of a part-width MOT plan. The FRA-71-0903 L/R structures over White Road will be replaced with single span prestressed concrete I-beam structures. All existing signs and guardrail will be replaced and the drainage was evaluated for replacement, repair, or reuse. In addition, the project involved 5 noisewalls and lighting design.

FRA-71-5.29

The proposed Exchange Road Waterline Extension Phase I project is being implemented by the Flatwoods-Canoe Run (FCR) Public Service District and is necessary to provide quality and dependable potable water and fire protection service to approximately 59 residences in the Holly and Otter Magisterial Districts of Braxton County, West Virginia. This project will be supplied via the FCR PSD’s Water Treatment Plant. The project includes upgrading an existing booster pump station and the construction of a water storage tank that will be sized to provide water to future phases of expansion of the system.

The Exchange Road Phase I project would tie-in at the existing Pressure Reducing Station near the intersection of State Route 4 and County Route 19/22. The Exchange Road Phase I project would serve residents along County Routes 19/22, 19/26 and 19/16.

The proposed project is estimated to cost $3,136,600 and is being funded by a $1,853,500 Appalachian Region Commission Grant; a $570,000 USDA Rural Development Grant; a $570,000 USDA Rural Development Loan and $142,500 in private contributions.

This Phase I Project will provide water to the planned Phase II Project that will serve an additional 39 customers. The Phase II Project is estimated to cost $2,498,027 and will be funded by an already committed $1,698,027 Abandoned Mine Lands Grant and a requested Small Cities Block Grant in the amount of $800,000.

Exchange Road Waterline Extension Phase 1

This award winning design build project with Schirmer Construction and Cleveland Metroparks was prompted by the necessary removal of the original Fort Hill steps due to severe erosion of the over 100’ high cliff adjacent to the Rocky River, next to the Rocky River Nature Center. ELR proposed a unique set of timber stairs connecting landings set on “tree” like support navigating the popular trail to 100’ above the valley. The stairs feature 2 overlooks and singular column foundations to minimize the impacts to the surroundings and view shed. This design won the 2018 ABCD award for Outstanding Special Purpose Bridge.
