Natural Resource Assessment

Woodland Corporate Center
Provided due diligence of a natural and cultural resource assessment including: NEPA check, endangered threatened and rare species habitat investigation, floodplain assessment, archaeological Phase I survey and wetland delineation for a potential site for a Government Services Administration building which included Section 106.

Wetland Mitigation

Port Columbus Red Lot
In four months, obtained a U.S. Army Corps of Engineers Individual 404 Permit and Ohio EPA 401 Water Quality Certification for unavoidable impacts to a wetland at Port Columbus International Airport Red Lot Parking Lot Expansion project. Williams Creek coordinated with Friends of Big Walnut Creek and the City of Gahanna to find a wetland mitigation site within the Big Walnut Watershed. Mitigation involved environmental science students from four local schools with the planting of native wetland vegetation.

Wetland Monitoring

Beachwood City Park
Provided wetland monitoring services for two restored wetland areas as part of a passive use park in the Shaker Boulevard Median to provide recreation, habitat, and educational opportunities. The 28 acre city park is located in an area excavated in the 1920’s for a proposed rapid transit line that was never extended into Beachwood. Due to prior disturbances, the park contained a unique environment of native prairie species amongst areas dominated by invasive species.

Monitoring activities have demonstrated the development of the two restored areas into diverse plant communities including emergent wetland, messic prarie and upland prairie. Services included monitoring the vegetation, hydrology and soils of the wetland areas and provided recommendations for an invasive species management plan.

Stream Restoration

Tipton Cicero Creek
Used bio-engineered bank restoration for 450 linear feet of Cicero Creek to serve as demonstration project. The project reduced sediment loading into the creek, increased aquatic habitat produced from woody vegetation overhanging the creek, and reduced mowing due to the establishment of a buffer along the project area.

Stream Relocation

Fort Harrison State Park
Provided due diligence, redesign, consultation, permit obtainment, and construction activities required for the impacts to approximately 600 linear feet of urban drain. Williams Creek developed grading, planting, and erosion control plans for the 900 linear feet of mitigated streams. Required mitigation ratios were determined to design the restoration of the stream channels and obtain the permits needed taking into consideration such as slope of stream channel, placement of spoils, types of plant material, construction sequencing, and success monitoring criteria.
