Featured Experience
The South Valley Parkway Project has provided a solution to concerns of residents along Middle Road regarding the compromised vehicular and pedestrian safety along this narrow corridor due to significant increase in traffic over the years.
The overall project is comprised of a new roadway alignment totaling 2.5 miles, one split interchange, five single lane roundabouts and one double lane roundabout to the South Valley Region in lower Luzerne County, PA. The project included the construction of a six-span two-lane bridge, carrying the parkway over Nanticoke Creek, Dundee Road and State Route 29, a single span two-lane bridge, carrying Main Street over State Route 29, and seventeen stormwater management basins which facilitated the separation of onsite stormwater and offsite watercourses to the highest standard. Safety and traffic congestion were the driving forces for PennDOT Engineering District 4-0’s purpose and need to move forward with the project. In addition, the project utilized what was otherwise abandoned coal land and transformed it into a viable traffic calming solution for the surrounding community. The new parkway connects Hanover Township with the City of Nanticoke, alleviating congestion to the residents along State Route 2008 (Middle Road) due to the commuters to Luzerne County Community College Campus and now restricted truck traffic.
Our team was the prime design consultant for this project completing Preliminary Engineering, Final Design, and Consultation during construction on behalf of the project owner PennDOT Engineering District 4-0.
Project Features:
- Selecting alignment of 2.5-mile new roadway while minimizing impacts and cost containment to fall within allotted funding.
- Excavation = 1.4M cubic yards, Rock blasting
- Six (6) Roundabouts - Five (5) Single Lane, and One (1) Double Lane
- Six (6) Span Concrete Bridge, One (1) Single-Span Concrete Bridge
- One (1) Box Culvert
- Four (4) Rock Structure Habitat created for Eastern Small-Footed Myotis Bats
- Seventeen (17) Storm Water Management Basins
- (2) Utility Main Relocations
- Acid Bearing Rock (ABR) – rock containing the sulfide-bearing mineral pyrite represents a potential source of Acid Rock Drainage (ARD). As a result, the construction specification required to minimize exposure to air and water without being covered to 5 days, and required an ABR disposal at the project’s approved waste site.

Penn Mag Inc. approached Verdantas to provide a geotechnical evaluation for a former industrial site located at the Port of Wilmington. Their goal was business expansion in the form of a new bulk material processing facility.
Penn Mag’s idea was to obtain high quality steel processing waste slag from Japan, ship it to Wilmington Delaware, refine it, and sell it to local ready mic concrete plants. The refined slag can replace virgin cement. The environmental benefits of the project included reuse of a former industrial site reuse of a recycled material in lieu of a completely manufactured product.
We were able to offer additional services, beyond geotechnical engineering, to help Penn Mag complete their project including critical environmental permitting that threatened to stop the project.

Building a new global waste material reuse business on the Delaware waterfront

The City of Philadelphia was more progressive than most older northeastern cities when addressing confined sewer overflow issues that are typical of aging and outdated underground infrastructures. Instead of the usual downgradient treatment plants, they decided to capture and infiltrate rainwater near the source, thereby mitigating flows into the already full sewers which were leaking into their streams and rivers. Such an undertaking relies not only on one big project, but on a multitude of smaller successes. Verdantas has been working with the City for over a decade, initially in reviewing private sector plans for upgrading detention and infiltration opportunities, to working with the City for the identification and design of City projects for the same purpose.
