STREAM, BANK STABILIZATION

By Chris McGovern

Akron, Ohio

Worked with engineers and landscaping firm to repair country club stream on holes 4 and 10 that were damaged by a volatile adjacent stream. We used matting to ensure the surrounding area was not damaged by our equipment as we excavated and widened the creek. Stream restoration, we rebuilt the channel and waterfall using placed rock and added j-hooks and v-weir structures to control the future stream water flow. In order to stabilize the banks (Bank Stabilization) and existing golf course greens we installed compost filter socks impregnated with aggregate and seed, and by installing weep holes in the existing sheet piled wall.

DAM REMOVAL, GOB FIRE

By Braeden Hurley

Coal Gob Fire Quenching – Wellston, Ohio

Removal of a dead lake from a former coal mine in Southern Ohio. While working on removal of a dead lake we uncovered a burning gob fire. We moved 45,000 cubic yards of cut to fill and cut to waste, installed 36" reinforced concrete pipe to relieve the dam, and dewatered over 100 million gallons. We moved over 16,000 cubic yards of earth to expose the gob fire, we extinguished,quenched, and then capped the site. To complete the project we seeded and mulched, returning the area to a grassy field as designed and nature intended.

LEAD AND ARSENIC REMOVAL

By Chris McGovern

City of Cincinnati

The Airport was built on a former military firing range and apple orchard. To complete the removal of all the lead and arsenic, we excavated and removed over 20,000 tons of treated and non-treated contaminated soil. Then we stabilized 11,000 tons of hazardous soil on site. We graded and capped the site all while complying with FAA, City and Airport Officials. Once the lead and arsenic we completely removed, the area was safe to put in a playground.

Blacklick Creek – Reynoldsburg, Ohio

Through stream restoration and bank stabilization, as the Environmental General Contractor, we were able to repair a dangerous situation facing an apartment complex in Central Ohio. The adjacent Blacklick Creek had eroded the bank to the point that a 40 foot cliff endangered both people and property. We cleared the area, relocated utilities, and diverted the stream. Next, we built a reinforced modular block wall, filled and graded the area, and placed rock channel protection in the creek to protect the bank. After completing the stream restoration and bank stabilization, the area is now safe leading to a fenced creek overlook.
