College Township, adjacent to State College and Penn State University Park’s campus, has experienced significant urban growth. Due to its location in the Spring Creek watershed and Chesapeake Bay watershed, sedimentation control due to stormwater runoff is important. This project involves retrofitting a 1.38-acre stormwater management basin in Penn Hills to include a runoff reduction function. The existing basin was originally constructed in the mid 1980’s to provide peak runoff control from 70 acres of the subdivision. Approximately 17% of the drainage area (12 acres) is impervious. The basin is currently vegetated with meadow grasses and wildflowers and consists predominantly of Hagerstown and Opequon Soils. These soils (Hydrologic Soil Group B) are well drained and have good infiltration characteristics. The township is interested in converting the basin from a peak-rate design to an infiltrating design that would provide significant sediment reductions. Preliminary analysis indicates that the basin can be retrofit to provide a minimum of 2.4 ac-ft. of runoff reduction from the 12 acres of tributary impervious area in Penn Hills. The Project would involve stormwater analysis, swale analysis, etc.
