The East and West of Algiers Canal Project provided Standard More...

Bank Stabilization and Wetland Terrace Creation at the Charles River Park

The Army Research Laboratory – Watertown (ARL-WT) was used as a munitions testing, manufacturing, and storage site from 1816 until 1995. In 1994, it was placed on the EPA Superfund National Priority List, with the Record of Decision calling for the remediation of soil and groundwater including organic and radioactive contaminants. The site encompasses a popular urban park designed by More...

Broad Meadows Marsh Restoration

At Broad Meadows Marsh in Quincy, MA, approximately 106 acres of tidal salt marsh habitat had been utilized as a dredging spoils disposal area at various times in the past. The Bioengineering Group was retained by the U.S. Army Corps of Engineers to study the feasibility of various alternatives under Section 1135. The intent was to restore marshland in a More...

Cane Ridge Wildlife Management Area, Least Tern Habitat Restoration

The Cane Ridge Wildlife Management Area (WMA) is a 474-acre property adjacent to the 3,000-acre Gibson Lake, an artificial cooling pond in Indiana. The Interior Least Tern is a migratory species that nests in shallow depressions on open sandy or gravel substrates naturally found in the Upper Mississippi Valley and Great Lakes Region. Due to the flood control and navigation More...

Emergency Riverbank Stabilization for Natural Gas Pipeline Protection

Riverbank erosion threatened to expose a regional main natural gas pipeline at a bend of the Manhan River in western Massachusetts. This constituted a potential emergency which needed an immediate solution; however, because of the presence of five endangered species, regulators denied the initial proposal for rock armor and required an ecologically sensitive treatment. More...

Hearthstone Quarry Brook Riparian Restoration Project

Due to heavy stormwater runoff from its urban surroundings, the Hearthstone Quarry Brook in Chicopee, MA suffered from severe erosion and channel incision. The brook runs through dense residential area and receives stormwater runoff from area roads, highways, homes, and parking lots. When a planned road expansion caused even more stormwater flow to the brook, the City of Chicopee recognized More...

Herrick Hollow Creek - Richardson Hill Road Landfill SFS, EPA Region 2 Superfund Site

The Bioengineering Group was retained by Amphenol Corporation to develop design measures to restore Herrick Hollow Creek at the Richardson Hill Road Landfill Superfund Site. Herrick Hollow Creek eventually discharges via Trout Creek to the West Branch of the Delaware River and the Cannonsville Reservoir operated by the New York City Department of Environmental Protection (NYCDEP). Previous stream restoration measures More...

Hop River Bank Stabilization

The Hop River is an important coldwater fishery and habitat to the wild brown trout, Salmo trutta. However, straightening and shortening of the channel two decades earlier in order to accommodate a state highway had triggered stream instability. Erosion was undercutting banks and increasing downstream sediment loading which in turn was smothering vital macro-invertebrate habitat and fish spawning grounds with More...

Mill Creek at Center Hill Landfill

The Bioengineering Group was requested by the City of Cincinnati, Office of Environmental Management to identify a cost-effective, environmentally sensitive bank stabilization plan for a portion of Mill Creek to halt erosion threatening to uncover waste materials contained in the Center Hill Landfill. The eroding bank was approximately 27 feet high and 600 feet long with clay strata overlain by More...

Neponset River Dam Removal Feasibility Study

The objective of the proposed project was to assess options for restoring fish passage, aquatic habitat and riparian habitat upstream of the Baker and T&H Dams on the Neponset River, located in Milton and Boston, Massachusetts. Although in the Algonquian Indian language, Neponset means the "Harvest River," referring to the exceptionally rich stock of shellfish and finfish in the river's More...

New Bedford Harbor Salt Marsh Restoration

New Bedford Harbor supports a large saltmarsh complex ringed by dense urban and industrial development. In 1983 New Bedford Harbor and some adjacent upland areas were added to the Superfund National Priorities List, and a Record of Decision adopted in 1998 directed its cleanup by the U.S. Environmental Protection Agency, implemented by the US Army Corps of Engineers. In this More...

Pope Branch and Lower Anacostia Park

The Pope Branch and Fort Dupont Creek tributaries of the Anacostia River in socio-economically challenged Northwest Washington, DC are heavily degraded urban streams partially buried in culverts. Urban development has caused substantial incision and habitat loss in the streams owing to flashy hydrology, deferred sewer maintenance, and contaminated storm water. Specific project objectives included daylighting the culverted streams and providing More...

Schoharie Creek Stream Assessment and Flood Mitigation Study Including Restoration Design

Schoharie Creek flows from the foot of Indian Head in the Catskill Mountains of New York and is twice impounded north of the Town of Prattsville to create New York City’s Schoharie Reservoir, and the New York Power Authority’s Blenheim-Gilboa Pumped Storage Power Project. During some winter storms, high stream flow and high reservoir levels cause a backwater area within More...

Shelby Bottoms Park Riverbank Protection Project

The Shelby Bottoms Greenway and Nature Park is one of the true jewels of Nashville’s Park and Greenway system. This 810-acre park offers 5 miles of paved multi-use trails and another 5 miles of primitive hiking trails. The area is well known as a haven for migrating birds and other wildlife.
