To develop a pipeline route that minimizes overall impact on landowners, the environment and cultural resources, we first conduct a series of civil and environmental surveys within a preliminary study corridor. Throughout the survey process, our survey teams evaluate the proposed route for constructability and environmental impacts, and also work closely with landowners to address their concerns.

The initial study corridor will be approximately 600 feet wide, which allows room for route adjustments to address landowner, environmental and construction related concerns. Once surveys are complete and a final route has been determined, the pipeline route will be reduced to a much narrower width – approximately 100 feet for construction and 50 feet for the permanent easement.

NEXUS works collaboratively with each landowner to perform surveys in a minimal amount of time with little to no inconvenience to their daily lives. While some states have existing laws that allow companies to access private properties for surveys, our preference is always to conduct these surveys with the landowner’s permission. Providing survey access to the property does not authorize NEXUS to build a pipeline on the property, nor does it imply that the landowner supports or agrees with the project. 

Below is a brief explanation for each of the main types of surveys we will perform.

Civil Surveys

Civil Surveys

Civil surveys involve small crews of four or five personnel walking along the study corridor to identify physical features such as homes and buildings, as well as delineate the boundaries of the study corridor with wooden stakes. Depending upon the length of the proposed study corridor on the property being surveyed, this activity should take no longer than two days for each property that will be surveyed.

Additionally, small teams of geologists perform geotechnical investigations to support the engineering design for the crossing of certain sensitive resources, roads and railroads located along the proposed pipeline route. The duration of geological surveys will vary depending on the conditions of each property; however, preliminary survey activity is usually completed in one or two days for each property.



Our specialized teams of environmental scientists perform in-depth surveys to evaluate certain environmental features within the study corridor.

For stream and wetland surveys, small crews of two or three environmental scientists will walk along the study corridor to identify wetland areas and surface waters, such as streams and rivers. In addition to marking wetland areas with small colored flags, the crews will measure certain water body features, such as width, depth, and ordinary high water mark. Depending on the length of the proposed route on a given property, this activity should take no longer than three days for each property that will be surveyed.

For plant and animal species surveys, small crews of ecologists, biologists and botanists will walk along the study corridor to identify and analyze the presence of any threatened or endangered species, if a suspected habitat is located within the staked area. Depending on the length of the proposed route of the pipeline on the property being surveyed, this activity should take no longer than three days for each property that will be surveyed.



Cultural resources surveys entail a team of two to four trained archeologists and architectural historians walking within the staked study corridor to identify historic structures such as homes and barns, as well as indicators of potential archaeological resources. If a site is suspected of archeological resources, then the archaeologists would return to that location with spade shovels to perform a limited excavation of a test hole measuring approximately 2×2 feet square and approximately 2 to 3 feet deep. Any area that is excavated for this type of survey will be restored to its preexisting condition once surveying is complete. Depending on the length of the proposed route of the pipeline on the property being surveyed, the archaeological walkover will take less than one day. If a limited archaeological excavation is necessary, it should take no longer than two days, weather permitting.
