Lick Run Conveyance Project

Cardno provided stream restoration and native landscape installation services for a large green infrastructure project separating stormwater (stream flow) and waste water from a legacy combined sewer system.

The Lick Run Valley Conveyance Project in Cincinnati will eliminate nearly 400 million gallons of combined sewer overflow annually and ensure that 88 percent of the flows during a typical year of rain will either reach the nearby treatment plant or be discharged as unpolluted stormwater to the Mill Creek.

The undertaking is the largest green infrastructure project ever completed in the City of Cincinnati. The project serves as a national model incorporating sustainable stormwater management, neighborhood redevelopment, transportation improvements, historic property reuse, neighborhood parks, and a new greenway.

Cardno teamed with Allison Landscaping, Kokosing Construction Contractors, and the Metropolitan Sewer District of Greater Cincinnati to fully deliver all native landscape installation and erosion control services along the approximately 1-mile long urban bio-engineered waterway as well as enhancement services for multiple bio-infiltration basins and water quality pond features within the greenway “treatment train.”

The new stream channel includes areas projected to contain hydrology for wetland habitats as well as riparian buffer and upland prairie habitats. The installation included:

  • 12.1 acres seeded with native riparian and upland seed mixes
  • 6.1 acres of native seeding protected with a TRM/Coir matting system to withstand high flow events
  • 6 acres of native seeding was protected with coconut fiber erosion control matting.

Additionally, more than 92,000 native species plugs were installed along the realigned stream corridor, within bio-infiltration basins, and along pond margins. These green infrastructure plantings are adapted for wetland conditions expected and intended to assimilate pollutants from more frequent urban stormwater runoff events. The wetland and riparian plants provide increased native habitat, particularly for pollinators, within the project corridor.

All plugs for the project were custom grown for the project by the Cardno Native Plant Nursery, in close collaboration with the project’s landscape architect (Human Nature). Cardno will provide maintenance services for one year after the final installation.

Local media coverage from the ABC and FOX media stations in Cincinnati spotlighted the project’s aesthetics and environmental benefits.
