L.K. Metzger Dam Rehabilitation Project
Ferguson Township Centre County, PA

A private landowner had a desire to repair and make necessary upgrades to the 2.0 acre Class C dam on his property. After receiving an inspection report from the DEP, the landowner contacted WHM to provide him with services to rehabilitate and upgrade the dam. The project will improve water quality in Spruce Creek by bank grading reducing erosion and sedimentation. The project will also improve safety and aesthetic value of the dam providing needed upgrades to ensure a properly functioning and aesthetically pleasing dam for future generations.

The project addressed concerns in the DEP inspection report and other goals set forth by the landowner. A summary of work includes: the repair of the primary spillway, backfill animal burrows or holes and patch with low permeability soil (LPS) to prevent seepage, grading and armoring the banks surrounding the impoundment to prevent erosion, dredging, backfilling downstream face of dam to eliminate backwater area, and the installation of a bridge spanning spillway to allow access to north side of landowners’ property.

During the design and permitting process, the flowing work was performed:

• Set up and attend a pre-application meeting with regulatory agencies to review project goals;

• Prepare appropriate permit applications required by regulatory agencies;

• Assist with field topographic survey;

• Conduct bathometric survey;

• GIS and CAD mapping;

• Review of PNDI (Pennsylvania Natural Diversity Index) for Threatened and Endangered Species and Cultural Resource Review;

• Develop plans for construction including, grading, spillway and bridge design, Erosion and Sediment Control, cut and fill volumes.

The completed permits are currently being reviewed by the PaDEP and pending approval. WHM has maintained close contact with the client to suit his need. Plans are to being construction of the rehabilitation project in the Spring of 2010.
