Ecological and environmental work was completed to assist utility siting and the land acquisition process for the Mid-Atlantic Power Pathway (MAPP) Project, a 150-mile corridor proposing 500 kilovolt (kV) aerial transmission and 640-kV DC aerial, underground, & submarine transmission proposed by Pepco Holdings, Inc. (PHI) to improve reliability and increase energy imports into the Mid-Atlantic Region.  Lead biologists were responsible for documenting the presence or absence of the Federally-endangered Delmarva fox squirrel within forested landscapes within Dorchester County, Maryland.  County-wide photo monitoring surveys provided pertinent information regarding Delmarva fox squirrel distribution trends and mitigation locations.  Rare, threatened and endangered (RTE) species habitat evaluations and directed RTE plant species surveys were performed from Calvert County, Maryland east to the Maryland/Delaware border.

PHI/Exelon Avian Protection Investigations  

Various Locations in DE, MD & NJ

Investigations along the Easton-Bozman transmission right-of-way in Talbot County, Maryland included raptor nest surveys, carcass surveys in outage areas, avian monitoring in high risk areas and pole configuration risk assessments.  Investigated outages from potential avian electrocution and recommended proper retrofitting measures including the installation of grounding conductor covers and jumper covers where inadequate phase-to-phase and phase-to-ground separation distances were encountered.  Bald Eagle and other avian monitoring are conducted along PHI/Exelon transmission lines along various routes through NJ, MD, and DE.  Tasks includes nest surveys, nest relocation and platform construction, and construction monitoring.

NJNG Southern Reliability Link - Ocean and Burlington Counties, NJ

Investigations along the NJNG Southern Reliability Link right-of-way through Burlington and Ocean Counties, inclusive of portions of the Lakehurst Naval Air Station property.  Biologists performed various threatened and endangered species habitat evaluations and species specific surveys.  Surveys included red-headed woodpecker call playback surveys, comprehensive floral surveys, target snake species nest surveys/habitat evaluations, grassland bird surveys, barred owl surveys, Phase I and II bog turtle surveys, northern long eared bat acoustic survey, and swamp pink evaluation.  Comprehensive final reports were prepared to address all Federally listed species (bog turtle, northern long eared bat, Knieskern's beaked rush, swamp pink), and to include all habitat evaluations and species specific surveys throughout NJDEP and NJ Pinelands Commission jurisdiction, inclusive of presentation of survey results, and recommendations for best management practices to ensure minimization of impacts to threatened and endangered species habitat.


Pennsy Supply Co. Mineral Quarry Expansion – Luzerne County, PA

Conducted summer mist-net Indiana Bat surveys and developed an Indiana Bat Habitat Mitigation Plan for a mineral quarry in Luzerne County, Pennsylvania.  The quarry is located within the area of a known Indiana bat hibernaculum and the Plan was developed to ensure protection of this endangered species pursuant to the Endangered Species Act of 1973.  The measures within the Plan satisfied USFWS concerns regarding expansion of quarry operations and Indiana bat protection.

Shulton Quarry Habitat Conservation Plan & Quarry Expansion
– Ocean County, NJ

Directed snake surveys on former quarry lands revealed the presence of hibernacula (dens), nests and critical foraging areas for a population of the state-threatened northern pine snake.  Staff at DuBois Environmental developed a Habitat Conservation Plan which secured Green Acres designation upon lands containing critical habitat for the northern pine snake.  Through coordination with the New Jersey Department of Environmental Protection and the New Jersey Pinelands Commission, this tract of land is now preserved in perpetuity for northern pine snake.  The client was permitted to pursue continued resource extraction on lands outside of critical habitat areas.


Collected field data, prepared application submissions and secured environmental permit approvals for numerous residential development projects throughout New Jersey.  Some of the residential projects where environmental services were provided include:

The Reserve at Pleasant Grove, Jackson Township, Ocean County, NJ

Prepared and received approvals for NJDEP Wetlands letter of Interpretation, NJDEP Wetlands Transition Area Waiver and Township Environmental Impact Statement for a 33-lot single-family residential subdivision.  The project also incorporated approval for 126+ acre portion of the site to be set aside for mitigation from unavoidable impacts to wetlands, open waters, and riparian zones associated with the Garden State Parkway-Interchange improvement project.  The breakdown of the mitigation area included approximately 51 acres of forested riparian zone enhancement, 14 acres of wetland enhancement and 61 acres of high quality forest/wetland preservation.  Combining the large scale restoration/mitigation project with a clustered development of the proposed development type resulted in creating a “regenerative development”.  These projects leave a softer touch on the landscape by integrating habitat restoration into residential living, creating an ecologically friendly project and resulting in a higher quality of life for residents. 


Route 301 Expansion Project - Section 29E and 29W, New Castle County, DE

Conducted an extensive trapping survey for the federally-threatened bog turtle and the possible occurrence of a number of other T&E species within or proximate to the proposed road expansion project.  Documentation obtained from completion of the survey was included in a required NEPA document.  Coordinated with the USFWS and DE Department of Natural Resources and Environmental Control to ensure compliance with all applicable regulations.  All studies were conducted in accordance with USFWS Section 7 consultation and State protocols for the species studied.  When applicable, the DE Department of Transportation (DelDOT) procedures manual was followed to the required standards.

Creek Road Bridge Replacement, Chadds Ford, Delaware County, PA

Trapping, nesting and visual site inspections were conducted for the Red-bellied Turtle (PA State-threatened) within and around the proposed area of disturbance associated with the Creek Road Bridge Replacement (Section DRB) Project over the Brandywine Creek in Chadds Ford Township.  Survey result satisfied PA Fish and Boat concerns regarding project activities and protection of the Red-bellied Turtle.
