G&A provided multi-disciplinary engineering services for a new maintenance facility and associated improvements. G&A assisted with land acquisition to support the expansion required to accommodate the new features. Working closely with the Architect and University, G&A developed an optimal site layout and improved function for personnel and equipment. A significant project component involved a new culvert spanning a tributary of the Tookany Creek, historically separating the area from the main campus. An existing pipe conveyance limited vehicular access and created a bottleneck in the stream, with associated backwater flooding. G&A performed a hydraulic analysis and developed streambank restoration plans for wider access to the maintenance area, eliminating flooding and establishing riparian protections. G&A obtained all necessary regulatory permits and approvals. Stormwater management features include a rain garden, underground detention bed, and green roof. The design, construction and green infrastructure practices demonstrate Arcadia University’s commitment to environment and place for staff and students alike.
Update: After a couple seasons and some significant rain events this culvert replacement and riparian improvement project is performing very well. The Client reports that the prior flooding, stream bank erosion, and scour issues are resolved and everyone is pleased with the improved look of the stream and this portion of campus in general. While this is only a localized section of stream, and with more work to do, this is not a signature project. However, initial high visibility restorations like this energize and engage folks, which opens the door to similar efforts. We are currently preparing a scope of work for a ~200 foot restoration/stabilization of this same tributary just downstream from this location.
