The selected lines will appear highlighted in light blue. If needed, choose Select by Rectangle from the drop-down menu.Ĭlick and drag a rectangular selection over the sewer line adjacent to Charleston Blvd. Step 2:select the desired area for buffering.Ĭlick on the select features button to turn it on. Right click on the Sewer Manhole layer, then Selection -> Make this the only selectable layer Step 1: create a separate layer for sewer main adjacent to Charleston Blvd.

In this part, you'll learn how to separate parts of a layer into sub-layers, and then create a different buffer for each sub-layer.įor this hypothetical project, we will create a buffer of 150 ft around the main sewer lines that are adjacent to Charleston Blvd and a buffer of 50 ft around the main sewer lines adjacent to Oakey Blvd. In some instances, you will have a single layer with different buffer requirements. The blue round shapes are the buffer areas around the sewer mains.
In the buffer window input the following: We'll first start with creating a buffer zone for all elements within a layer. We assume that, in our hypothetical project, a buffer was put as a constraint on the project to prevent any ground drilling from damaging the mains this means that we would have to mark the buffer on our map so that we know the area to avoid.
