2.1.2 Landfall and Overland Area

The landfall and overland constraints analysis assumes the use of existing ROWs for potential co-location

with OSW cables due to the extent of developed land and associated spatial limitations. The four

categories of existing ROWs considered include:

• Existing electric transmission lines, both aboveground and underground;

• Arterial roadways;

• Metropolitan Transportation Authority passenger lines; and

• Natural gas pipelines.

Other ROWs may be suitable, for example, defunct aqueducts, although available GIS data do not address

status or feasibility of reuse. Freight lines were excluded because of the increased safety and security

challenges associated with siting a transmission line parallel to those lines. In addition, the ROW category

for arterial roadways reflects avoidance of small roads or roads with only one lane in either direction;

however, smaller roads may represent the preferred option in some cases. Within the arterial roadway

category, NYSDOT identified the following parkways with requiring FHWA approval for an exception to

the NYSDOT Utility Accommodation Plan for non-transportation uses that may require consultation with

FHWA: Bethpage, Heckscher, Loop, Ocean, Sagtikos, Sunken Meadow, Wantagh, Meadowbrook,

Northern State and Southern State Parkways, and the Robert Moses Causeway.

The analysis assumes use or expansion of existing ROWs and not the creation of new ROWs from the

identified undersea landing zones to one or more POIs. Table 2-2 identifies the 21 POIs included in one

or more of the onshore zones, which were representative substations considered potentially feasible POIs

in the New York Power Grid Study analysis.
