West Jefferson Hills High School

West Jefferson Hills School District selected a 161-acre site for the future home of their high school complex. The proposed development will cover approximately 45 acres and include a 269,000-SF school building and district administration offices. Langan conducted natural resource services to aid in the selection of the most appropriate location for the complex within the 61-acre site. Our environmental team conducted a Phase II Environmental Site Assessment (ESA), which included soil sampling at 20 soil boring locations and soil vapor sampling at four locations. Langan subsequently completed a Human Health Risk Assessment (HHRA) to evaluate the risk posed by existing site conditions to potential future site receptors associated with the school, which showed no unacceptable carcinogenic or non-carcinogenic risks to future receptors.
