To investigate this new alternative, further review of the location of the Hydro One’s high voltage oil-filled transmission lines was undertaken with test pits to locate the lines. This investigation has provided new information that the double staging areas to the north alternative is feasible. In addition, an underwater marine archaeological assessment has cleared the area of archaeological potential. The additional review and recommendations were presented to the City of Ottawa, NCC and Parks Canada to confirm the viability and support was received for both the staging areas being located to the north with temporary closures of the two NCC parkways. This new preferred alternative reduces permanent property impacts to 221 Echo Drive and 3/5 Hawthorne Avenue and does not require crossing the City’s watermain.
