Selecting the most cost efficient route may be the most important part of the pipeline phase. In order to select a route from point A to point B, the company needs to be familiar with the area between the two stations. What is out there? K and M pulls all aerial maps for the area locating rivers, marshes, lakes, and any wetlands. Next, we look for federal lands, state lands, and cemeteries. Then, we locate rights-of-way for roads, railroads, and any other pipelines in the area before researching tax ownership maps and information to plan the most cost efficient route.
