A major South Jersey energy provider needed to upgrade outdated transmission lines and substations between the Delaware Bay area and the Jersey Shore. Replacement of hundreds of lattice towers with steel monopoles and expansion of existing substations required large-scale archaeological and historic architectural studies in order to comply with state and federal regulations.
The transmission corridors passed through diverse environmental settings, some of which were particularly sensitive with regard to prehistoric archaeological sites. A number of the proposed monopoles fell within previously identified archaeological sites. Additionally, the corridors crossed areas of early settlement, intersecting possible historic archaeological sites and passing within view of over 200 potentially historic buildings. The longest of the transmission corridors was itself a potential historic resource, having played a role in the initial electrification of southern New Jersey.
