Our work efforts on land development applications in the Township are comprehensive, including pre-application meetings with applicants, technical review, escrow review, construction inspection, and final walk through/punch list creation. In addition to the development plan review services, Princeton Hydro provides routine construction oversight and erosion and sediment control inspections for the large-scale construction projects within the Township. Implemented BMPs include green roofs, porous pavement, and various infiltration/detention BMPs. Many projects have challenging existing site conditions including carbonate geology, floodplains, and historic fill. Furthermore, many of the ongoing projects are redevelopment projects which have semi-urban characteristics in terms of existing site constraints.
