Hampden Marketplace

Advantage Engineers is providing ecological consulting services for the proposed Hampden Marketplace, a 74 acre retail development located in Cumberland County, Pennsylvania. The development includes a 74,000 sf Giant Food Store, 12,800 sf of retail establishments, and a 2,000 sf car wash with a fueling facility.

Our services include:

  • Wetland delineation 
  • Coordination of pre-application meetings with state and federal agencies 
  • Obtained a preliminary Jurisdictional Determination (JD) from the U.S. Army Corps of Engineers (USACE) Baltimore District 
  • Wetland replacement design
  • Prepared & coordinated Chapter 105/Section 404 Joint Permit submission

The site had many development constraints including two streams, three wetlands (including one large wetland complex), and a pond. In addition, sewer rights-of-way traverse two property boundaries for access and maintenance to its existing sanitary sewer facilities. The original proposed plan involved the total fill of the existing pond, 0.822 ac of wetland impacts, and a 97 ft stream enclosure for a road crossing.

Advantage coordinated a series of pre-application meetings with the civil engineer, the USACE, and PA Department of Environmental Protection (DEP) and provided an integral mediary role in implementing additional avoidance and minimization measures of the initial proposed impacts.

Advantage completed the geotechnical design of a retaining wall that made avoiding some of the wetland impacts possible.  Advantage also successfully obtained a preliminary JD during this process. A Phase I Bog Turtle Habitat Assessment was also completed, resulting in no potential bog turtle habitat.  A concurrence letter from the U.S. Fish & Wildlife Service was obtained.  

Once impacts were adequately avoided and minimized, Advantage evaluated the functions and values of the existing wetlands and analyzed existing hydrologic and soil conditions. A location was selected and more detailed site analysis performed. Advantage utilized this data to develop a wetland replacement design, construction sequence, and planting plan in coordination with the civil engineer.
