Project Details

Keller Engineers performed various survey and environmental services on this 170-acre site in the historic lakebed of the South Fork Dam and Conemaugh Lake.

All services were completed using the protocols and procedures specified by the United States Army Corps of Engineers.  The wetland boundaries were located by field survey and acreage determined of individual wetlands and of Cowardin types.  GIS data layers were developed for all delineated wetlands then geo-referenced onto an aerial photograph.

I probably don’t say this enough, but we so appreciate the quality of work Keller Engineers does. The fact that they include building footprints and natural features makes these surveys super useful. I’m reminding my colleagues in other counties that their surveyors need to up their quality. F. Mark Schiavone, Executive Director Berkeley County Farmland Protection Board
